Different types of well-being are likely to be associated with different kinds of behaviors.
The first objective of this study was, from a subjective well-being perspective, to
examine whether harmony in life and satisfaction with life are related differently to
cooperative behaviors depending on individuals’ social value orientation. The second
objective was, from a methodological perspective, to examine whether language-
based assessments called computational language assessments (CLA), which enable
respondents to answer with words that are analyzed using natural language processing,
demonstrate stronger correlations with cooperation than traditional rating scales.
Participants reported their harmony in life, satisfaction with life, and social value
orientation before taking part in an online cooperative task. The results show that the
CLA of overall harmony in life correlated with cooperation (all participants: r = 0.18,
p < 0.05, n = 181) and that this was particularly true for prosocial participants (r = 0.35,
p < 0.001, n = 96), whereas rating scales were not correlated (p > 0.05). No significant
correlations (measured by the CLA or traditional rating scales) were found between
satisfaction with life and cooperation. In conclusion, our study reveals an important
behavioral difference between different types of subjective well-being. To our knowledge,
this is the first study supporting the validity of self-reported CLA over traditional rating
scales in relation to actual behaviors.

INTRODUCTION
Different types of well-being are proposed to be associated with different kinds of behaviors
(e.g., Ryan and Deci, 2001; Kjell, 2011). Individuals associate the pursuit of harmony in life with
cooperation and related words (e.g., together, unity, and mutual), whereas the pursuit of satisfaction
with life is associated with words relating to self-fulfilment (e.g., achievement, goals, and winning;
Kjell et al., 2016). This distinction is also found when having participants describe their level (rather
than pursuit) of harmony in life versus satisfaction with life using open-ended language-based
measures, but not when using traditional numeric rating scales (Kjell et al., 2019). The present
study allowed individuals to describe their well-being in their own words and had two objectives.
The first objective was related to well-being and cooperation, i.e., to examine if two cognitive

Kjell et al. Computational Language Assessments: Harmony and Cooperation
components of subjective well-being namely, overall harmony
in life and overall satisfaction with life as reported prior to a
social dilemma game are related to cooperative behaviors [while
also controlling for values in the form of their social value
orientation (SVO)]. The second objective was related to the
assessment method, i.e., to examine whether quantitative open-
ended language-based assessments (referred to as computational
language assessments) more clearly than rating scales distinguish
between harmony in life and satisfaction with life in relation to
the behavioral outcome of cooperation. These objectives were
examined in a social dilemma game where cooperating increased
the joint outcome and not cooperating gave one the chance to
personally achieve the highest outcome.
Satisfaction, Harmony, and Cooperation
The definitions of satisfaction with life and harmony in life as
well as related empirical research suggest that harmony in life is
more related to cooperative behaviors than satisfaction with life.
Diener et al. (1985) highlight that satisfaction with life concerns
a “cognitive, judgmental process (p. 71) regarding a person’s
evaluation of their life situation as a whole. As such, satisfaction
with life is defined as having surroundings and circumstances
according to ones expectations and ideals and in accordance
with ones own criteria (Diener et al., 1985). Harmony in life,
on the other hand, relates to being in balance and fitting in with
ones surroundings and circumstances (e.g., see Kjell et al., 2016;
Kjell and Diener, 2020). Li (2006) stresses that harmony entails
favorable relationships, and Li (2008) points out that “harmony
is by its very nature relational. It is through mutual support and
mutual dependence that things flourish (p. 427). Considering the
different definitions, harmony in life and satisfaction with life are
likely to be associated with different actions and behaviors (e.g.,
see Kjell, 2011).
Indeed, empirical research demonstrates differences in how
individuals view their pursuit of harmony in life and satisfaction
with life. In a direct comparison between harmony in life
and satisfaction with life, Kjell et al. (2016) revealed that
participants describe their pursuit of harmony in life with words
relating to interconnectedness with other people (e.g., peace,
balance, cooperation, unity, agreement, accord, concord, together,
friendship, and forgiveness). Meanwhile, the pursuit of satisfaction
with life is described with words relating to self-centered (cf.
ones own criteria) mastery (e.g., money, achievement, wealth,
gratification, goals, work, career, winning, success, and job).
Similarly, Kjell et al. (2019) demonstrate that many of these
aspects can also be seen in participants descriptions of their
personal state of harmony in life versus satisfaction with life.
Cooperation in the Give-Some Dilemma
Game
Degree of cooperation in this study was measured in a one-
shot give-some dilemma game (GSDG; e.g., see Van Lange and
Kuhlman, 1994). In this dilemma game participants are given
an amount of money and grouped into pairs. In a simultaneous
interaction, they choose to keep their money or give some or
all of it to the other person. Participants are informed that any
money that is given away doubles in value for the receiver. Hence,
keeping the money increases the chance to personally get the
highest amount (cf. satisfaction with life), while giving the money
to the other person increases the joint outcome (cf. harmony
in life). Participants are informed about the other’s decision at
the same time. Degree of cooperation is thus operationalised as
the amount of money each participant decides to give away. The
amount of money participants give is hypothesized to be related
to their reported level of harmony in life and satisfaction with life
in addition to other factors such as their SVO as discussed next.
Prosocials and Proselfs
An individual’s SVO is a stable characteristic that predicts
the degree of cooperation in social dilemmas (Van Lange and
Kuhlman, 1994; VanLange et al., 1997; Balliet et al., 2009), and
it is defined as an individual’s preference for a specific resource
allocation between others and oneself (McClintock, 1972). Even
though individuals can be categorized into several different
SVOs, at least three are typically identified: (1) individuals with a
cooperative SVO who focus on maximizing the joint outcome for
self and others, (2) individuals with a competitive SVO who focus
on maximizing their own outcome relative to others, and (3)
individuals with an individualistic SVO who focus on maximizing
their own outcome with little or no consideration of the outcome
for others (VanLange et al., 1997). Individuals categorized with
a cooperative SVO are often referred to as prosocials, while
individuals categorized with an individualistic or competitive
SVO are referred to as proselfs.
Because SVOs are found to be stable motivations, this
distinction has played an important role in research investigating
various situational and contextual variables in relation to
cooperation. For example, it was demonstrated that inducing
guilt (as compared with a neutral state) in participants
categorized as proselfs increases cooperation in a prisoner’s
dilemma game (Ketelaar and Au, 2003) and a GSDG (de Hooge
et al., 2007). In another study using a GSDG, it was demonstrated
that inducing fear (as compared with a neutral state) decreases
cooperation in prosocials (Nelissen et al., 2007). Further, Kjell
and Thompson (2013) compared joy, guilt, and a neutral
condition within a prisoner’s dilemma game. That study revealed
a significant relationship between cooperation and SVO, but no
significant differences in regard to the emotional conditions.
It was suggested that cognitive resources and strategies (cf.
the cognitive subjective well-being components of harmony
in life and satisfaction with life) rather than experimentally
induced emotions may have a stronger influence on cooperation.
To our knowledge, there are no studies comparing the effect
of the cognitive components of subjective well-being (i.e.,
harmony in life versus satisfaction with life) and their respective
relationship to cooperation.
Open-Ended Computational Language
Assessments Versus Numerical Rating
Scales
Subjective well-being is typically measured using scales
comprising items (e.g., I am satisfied with life; Diener et al., 1985)
Frontiers in Psychology | www.frontiersin.org 2 May 2021 | Volume 12 | Article 601679

Kjell et al. Computational Language Assessments: Harmony and Cooperation
with a closed-ended response format (e.g., ranging from
1 = Strongly disagree to 7 = Strongly agree). In contrast, Kjell et al.
(2019) developed computational language assessments that allow
respondents to answer questions about psychological constructs
with words that are analyzed using natural language processing.
This method enables both measuring as well as describing
the psychological construct under investigation. Importantly
it was shown that computational language assessments, as
compared to traditional numerical rating scales, discriminate
more clearly between harmony in life and satisfaction with
life. For example, the numerical rating scales Harmony in Life
Scale (HILS; Kjell et al., 2016) and Satisfaction With Life Scale
(SWLS; Diener et al., 1985) were strongly correlated, whereas
the computational language assessments of harmony in life
and satisfaction with life were only moderately correlated.
Furthermore, plotting the word responses demonstrated
clear differences between words relating to harmony versus
satisfaction when plotting according to the computational
language assessments. That is, covarying the computational
language assessments of harmony in life with satisfaction with
life (or vice versa) when plotting significant words yielded a
clear independence between the constructs. Interestingly, these
differences between harmony and satisfaction were not clear
when discriminating between the words using numerical rating
scales rather than semantic similarity scales, nor were they clear
when covarying the corresponding numerical rating scales. This
discriminative property of computational language assessments
suggests that they more clearly than numerical rating scales can
predict behavioral outcomes that are relevant for one, but not
another, psychological construct such as harmony in life and
satisfaction with life.
Objectives and Hypotheses
The study had two objectives. The first objective was to
examine if overall harmony in life and overall satisfaction
with life reported before a social dilemma game are related to
cooperative behaviors (while also controlling for values in the
form of their SVO). The hypotheses related to this objective
concerned how differently the pre-interaction language-based
and numerical measures of harmony in life and satisfaction with
life are related to cooperation in the GSDG depending on the
individual’s SVO.
H
1
. Level of overall harmony in life correlates positively
with cooperation, especially in those categorized
as prosocial.
H
2
. Level of overall satisfaction with life correlates
negatively with cooperation, especially in those
categorized as proself.
The second objective was to examine whether computational
language assessments, as compared with rating scales, more
clearly distinguish between harmony in life and satisfaction
with life in regard to cooperation in the GSDG. This is,
for example, based on evidence showing that computational
language assessments, as compared with numerical rating scales,
discriminate more clearly between constructs (Kjell et al., 2019).
Therefore, it was hypothesized that:
H
3
. Computational language assessments discern the
predictions in H
1
and H
2
more strongly than numerical
rating scales (i.e., they reveal stronger correlations).
H
4
. The relationships in H
1
and H
2
are also discerned
using keyword plots based on the computational language
assessments. Descriptive words that participants use to
describe their overall harmony in life (e.g., peaceful and
balance) are associated with high cooperation, whereas
words describing their overall satisfaction with life (e.g.,
happy and fulfilled) are associated with low cooperation.
MATERIALS AND METHODS
Participants
Participants were recruited from Amazon’s Mechanical Turk, a
website that enables one to pay participants to partake in studies
(Paolacci et al., 2010; Mason and Suri, 2012). A total of 200
participants were recruited at once, before starting the analyses.
The size of the sample was based on an 80% power to detect a
correlation of r = 0.2 (alpha level = 0.05, two-sided), which is
a correlational size that can be considered theoretically relevant
for the investigated hypothesized positive correlation between
harmony in life and cooperation. Four participants were removed
due to failing to correctly respond to control items (a method that
has been shown to increase the statistical power and reliability of
datasets; e.g., see Oppenheimer et al., 2009), two were removed
for raising suspicion of responding insincerely and not answering
the questions independently
1
, and 13 were removed for being
suspicious about the authenticity of the interaction in the last
feedback question (see section “Material”). The final sample
consisted of 181 participants (female = 86; male = 94; other = 1)
with a mean age of 34.34 (SD = 10.21; range = 19–63) years and
a mean of 4.6 (SD = 1.7) on the perceived financial situation
scale (range 1 = “Our income does not cover our needs, there
are great difficulties” to 7 = “Our income covers our needs, and
we can save”). Participants mainly came from the United States
(United States = 156; India = 20; other countries = 5).
1
The two participants were removed for raising suspicion of not completing
the study independently. The two participants answered all the word-response
questions identically three of the four questions they answered by repeatedly
writing “yes, and in response to the overall harmony in life question both had,
in the same order, answered: good, marvelous, kudos, extraordinary, elegant,
resplendent, enormous, glory, stupendous, sumptuous.” On the HILS and the SWLS,
one reported a total score of 35 on both scales, and the other a score of 33 on
both scales. Further, both reported the same on the demographic questions, gave
$1 in the interaction, and answered the third presented alternative on the Triple-
Dominance Measure (hence the potential insincerity). They reported different
worker IDs but had very similar, overlapping start and submit times. Although
keeping these participants in the study lowered the overall correlation between the
computational language assessment of overall harmony in life and cooperation, it
did not considerably affect the other correlations. Further it did not change the
remaining parts of the results as the participants SVOs were uncategorized (i.e.,
not categorized as prosocial or proself).

Material
Rating Scales Measures
The HILS (Kjell et al., 2016) consists of five items (e.g., “I am in
harmony”) answered on a 7-point scale ranging from 1 = Strongly
disagree to 7 = Strongly agree. Cronbachs alpha in the current
study was 0.94 (Mc Donald’s ω total = 0.96).
The SWLS (Diener et al., 1985) comprises five items (e.g.,
“I am satisfied with my life”) answered on the same scale
as the HILS. Cronbachs alpha in the current study was 0.92
(McDonalds ω total = 0.95).
The Triple-Dominance Measure (TDM; VanLange et al., 1997)
was used to assess SVO. The TDM comprises nine items, which
each present three distributions of “valuable points” that are
differently shared between the respondent and a hypothetical
unknown other person. Distributions with equal division of
valuable points are categorized as prosocial, and distributions
where respondents get more than the other are categorized as
proself. If six or more answers consistently fall within one of the
categories, the respondent are classified accordingly.
Demographic questions included gender, age, first language,
and country of origin as well as perceived financial situation (i.e.,
“Does the total income of your household allow you to cover
your needs?”; answered on a scale ranging from 1 = “Our income
does not cover our needs, there are great difficulties” to 7 = “Our
income covers our needs, and we can save”).
The control items On this question please answer the
alternative ‘neither agree nor disagree”’ and “Answer ‘disagree
on this question” were included with the numerical rating scales
to ensure that the participants had read the questions within the
survey. Participants that did not answer these items correctly
were removed from the analyses. This kind of method has been
demonstrated to ensure high statistical power and reliability (e.g.,
see Oppenheimer et al., 2009).
Word and Text Measures
The Word-Response Harmony Question (Kjell et al., 2019) is stated
as “Overall in your life, are you in harmony or not?” The Word-
Response Satisfaction Question (Kjell et al., 2019) reads “Overall
in your life, are you satisfied or not?” These word-response
questions are presented with the instructions to answer using 10
descriptive words for each question (for full instructions, see Kjell
et al., 2019).
A Feedback Question asked participants to provide a brief
description of their thoughts regarding the GSDG. Three
psychology researchers (two with a Ph.D. and one Ph.D. student)
not involved in the study, and blind to how the participants
responded to other questions, evaluated the answers based on
whether they raised any suspicion that the interaction did not
involve another person. Participants were removed when at least
two out of the three assessors indicated raised suspicion. In total
13 participants were removed (all three assessors agreed on 12
answers and on 1 answer two raters indicated suspicion; only one
other answer was indicated as raising suspicion by one assessor,
which was thus kept).
The Affective Norms for English Words (ANEW; Bradley and
Lang, 1999) enabled the construction of language predicted
valence scales (see the section on “Natural Language Processing
and Statistical Analyses”). These affective norms comprise a large
number of words that have been rated by individuals in terms
of valence, arousal, and dominance. The valence model used in
this study to predict the valence of responses demonstrated a
cross-validated Pearson r of 0.73 (p < 0.001, N = 1025).
Intervention
The GSDG (Van Lange and Kuhlman, 1994; de Hooge et al.,
2007) involved giving each participant $1.0 and the option to
give the money to an interacting partner who simultaneously
had the same opportunity. However, the experiment involved a
deception in which the “partner” consisted of a computer that
randomly responded by either giving $0 or $1. Participants were
informed that the amount they decided to give away would
double in value for the receiver but that none of the parties in
the interaction would know in advance what the other decided
to give. The available alternatives to give ranged from $0 to $1,
with $0.1 increments. The degree of cooperation was measured
as the amount of money the participant decide to give. This was a
“one-shot” interaction, meaning that it only took place once.
Procedure
Participants were informed that the study required English as the
first language, that it was voluntary to partake, and that they had
the right to withdraw at any time. Further, they were informed
that the experiment involved interacting with another person
regarding money, and this description was aimed to be as neutral
as possible by avoiding more value-laden words such as being
cooperative or about winning or losing. Participants were paid
$0.5 to complete the study and told that they would keep any
money from the interaction task.
After having agreed to partake in the study, participants
were informed about how the interaction task (i.e., the GSDG)
works and that both parties had to submit their response
before they were shown the others response. To ensure that
the participants had understood the task, they had to answer
hypothetical questions correctly before being able to continue
(see Supplementary Material Appendix I). Subsequently,
participants were presented with the demographic questions,
followed by the well-being questions. Participants were randomly
assigned to either answer the word-response questions in random
order first or the rating scales in random order first.
Before the interaction task started, participants were presented
with a message reading, “Searching for another person. Please
wait, and after 16 s another sign popped up reading, “Connecting
you with another person.” Participants were then presented with
a summary of the instructions of the game and the response
alternatives regarding the amount to give to the other person.
When they had answered, the participants were presented with
the text reading, “Please wait while processing. The other person
cannot see your response.” This was followed by the message:
“Please wait for the other person to submit their decision.”
Subsequently, they were presented with the result of the task (e.g.,
“The other person decided to give you $0. You gave $0. In total,
you get $1 and the other person gets $1.”).
After the interaction, participants answered two questions
about their momentary experience of harmony in life and

Kjell et al. Computational Language Assessments: Harmony and Cooperation
satisfaction with life (which were not analyzed or reported in
this study due to its exploratory nature) followed by the TDM.
Lastly, before being debriefed, the participants were asked to
leave feedback about the interaction. The study took on average
16 min to complete.
Ethical Considerations
The studies received ethical approval from the Regional
Ethical Committee in Lund, Sweden. Prior to participating, all
participants received information about the study and were asked
for consent to participate. They were informed that participation
was anonymous and voluntary and that they could withdraw
at any time without having to give a reason. At the end of the
study, the participants were given more information about the
study and were informed about the deception and why it was
important, and they were informed that because of this deception
they received the maximum possible amount from the GSDG.
Natural Language Processing and
Statistical Analyses
The Semantic Space and Representations
The word data were analyzed with the r-package Text 0.9.0
2
(Kjell et al., 2021). The words generated in the current
study were given their semantic representations (i.e., vectors
of numeric values describing each word) from a previously
created semantic space (used and described in Kjell et al.,
2021). The semantic space was created using latent semantic
analyses (Landauer and Dumais, 1997) based on singular
values decomposition (Golub and Kahan, 1965) on the co-
occurrences of 1.7 × 10
9
words from the English Google 5-g
database. The semantic space includes semantic representations
for the 120,000 most frequent English words, in which each
word is described in 512 dimensions (for more details, see
Kjell et al., 2016).
Word responses were cleaned in accordance to the procedures
put forward in Kjell et al. (2019). Words were spelled according
to American spelling, and misspelled words were corrected
only when the meaning was clear, otherwise they were ignored.
Successively repeated words or instances of “NA” or similar were
removed. Answers comprising sentences or strings of words
rather than one descriptive word in each response box were
removed. And words that did not have a semantic representation
in the semantic space were returned as missing values.
Because the responses to the word-response questions
comprised several words, the semantic representations of the
words were added together using the mean of each dimension
to create one representative semantic representation for each
word-response question. These semantic representations were
subsequently used to create semantic similarity scales, language
predicted valence, and the word plots as specified below.
Semantic Similarity Scales (SSS)
The values that compose the semantic representations can be
seen as coordinates in a high-dimensional space, and the closer
together the semantic representations of two words/texts are
the more semantically similar they are. Hence, the semantic
2
www.r-text.org
similarity between two words/texts can be represented by the
cosine of the angle between the two semantic representations
(Landauer and Dumais, 1997). In the current study, we measured
the level of a psychological construct by measuring the semantic
similarity between responses to the word-response questions
and the corresponding word-norms. For example, if a person’s
response to the harmony in life question was semantically similar
to the harmony in life word-norm, this person was considered
to have a high level of overall harmony in life. High unipolar
semantic similarity is the semantic similarity to the targeted
construct (e.g., harmony in life), low unipolar semantic similarity
scales are the opposite of the target constructs (e.g., disharmony
in life), and bipolar semantic similarity scales are the low unipolar
scale subtracted from the high unipolar scale (e.g., the harmony
in life SSS minus the disharmony in life SSS).
Language Predicted Scales
The values in the semantic representations can also be used in
multiple regressions to create models predicting certain semantic
characteristics of a word/text. In the current study, we employed
language predicted valence scales. These are based on the ANEW
word list where approximately 1,000 words have been rated by
individuals in terms of their negative or positive valence. In the
multiple regression (y = c
x), the semantic representations (x; i.e.,
vectors) of the words were used to predict the valence (y) rated by
participants, in which the coefficient (c) describes the relationship
between the words and the valence. This regression model was
applied to the word responses in the current study to estimate
their valence (i.e., the regression model was a language predicted
valence scale). This model was created using ridge regression
(with a penalty grid ranging from 10
16
to 10
16
), where cross-
validation was used to evaluate the model (for more details, see
Kjell et al., 2021).
The SSS and the language predicted scales were used in the
correlations to understand their relationship to rating scales
and cooperation.
Supervised Dimension Projection Plots
Plots were used to visualize words that were statistically
significant in relation to the specified categories or dimensions
(i.e., axes) under investigation. In the current study words that
significantly differed in their semantic representation between
responses to the harmony in life versus the satisfaction with life
questions were plotted on the x-axis, and on the y-axis the words
were plotted according to the degree of cooperation. Words that
statistically significantly differed on a specified dimension, were
plotted in color (rather than in gray), and the font size of the word
indicated its frequency in the data.
The supervised dimension projection plot compares two
groups responses to different questions (e.g., harmony in
life versus satisfaction with life responses) or low versus
high cooperation on a scale using mean split. To achieve
this, a semantic representation is first constructed to capture
the difference between the two groups, and this semantic
representation (point in space) can be seen to form a line through
the origo (and is referred to as the aggregated direction embedding
line). The aggregated direction embedding is constructed by taking

Kjell et al. Computational Language Assessments: Harmony and Cooperation
the mean of all semantic representations in each group and then
subtracting the two representations.
Finally, all the individual words in the word responses
are “projected onto the aggregated direction embedding line.
The projection is achieved by first “anchoring” all of the
individual words representations in space by subtracting the
second group’s aggregated semantic representation from each
words representation and then using the dot product to
project each words anchored representation (for more details,
see Kjell et al., 2021). To statistically test the words, a dot
product null distribution is created by calculating the dot
product among randomly selected semantic representations
and an aggregated direction embedding created from randomly
swapping words semantic representations from the two groups.
Multiple comparisons are corrected using the false discovery rate
(FDR) correction.
Statistical Analyses
To examine the relationships between variables, Pearson r
are used when both variables are normally distributed, and
Spearman’s rho are used when at least one of the variables are
not normally distributed. To examine the relationship between
two variables whilst controlling for other variables we use partial
correlation (e.g., see Kim, 2015).
R-Packages
All analyses were carried out in R (R Core Team, 2020) using
RStudio (RStudio Team, 2020). Apart from the text package
(Kjell et al., 2021), the following packages were used: tidyverse
(Henry and Wickham, 2020), Hmisc (Harrell et al., 2020),
dplyr (Wickham et al., 2020), ppcor (Kim, 2015), psychometric
(Fletcher, 2010), reshape2 (Wickham, 2007), ggplot2 (Wickham,
2016, p. 2), data.table (Dowle and Srinivasan, 2019), lm.beta
(Behrendt, 2014), lattice (Sarkar, 2008), effsize (Torchiano, 2020),
and WRS2 (Mair and Wilcox, 2019).
RESULTS
Descriptive Statistics
Ninety-six participants (53%) were categorized as prosocials,
70 (39%) were categorized as proselfs, and 15 (8%) were
uncategorized. On average the participants gave $0.45 (SD = 0.41;
prosocials: Mean = $0.52, SD = 0.41; proselfs: Mean = $0.34,
SD = 0.39). The cooperation variable exhibited a bimodal,
rather than a normal, distribution, and the semantic similarity
scales contained some considerable outliers. Because a few
participants had, for example, just replied yes or no to the
word-response questions, and because both of these opposing
answers yielded outliers of low semantic similarity, outliers
with a z-score more extreme than ±3.29 were removed for
all semantic similarity scales (see Table 1). Table 2 presents
correlations among the included well-being measures. The
highest correlation was between the HILS and SWLS (r = 0.84,
p < 0.001), whereas the computational language assessments
showed lower intercorrelations (e.g., the semantic similarity score
of the harmony in life responses and norms with the satisfaction
with life responses and norms yielded an r of 0.59, p < 0.001).
The Well-Being and Cooperation
Objective
In accordance with H
1
, the CLA of overall harmony in life (i.e.,
the SSS between the word-responses of the harmony question
and the harmony in life word-norm) was positively correlated
with cooperation, and this was strongest in prosocials (r = 0.35,
p < 0.001; see Table 3). However, in contrast to H
1
, this
relationship was not found with the HILS. In contrast to H
2
,
measures of overall satisfaction with life were not significantly
related to cooperation. Figure 1 shows these correlations, where
the correlations were controlled for age, gender, perceived
financial situation, and all the other well-being-related measures
(all presented in Table 3), and only the correlation between
the computational language assessment of overall harmony in
life and cooperation was significant (r = 0.41, p < 0.001).
It is also worth noting that there is a significant positive
correlation between the Disharmony semantic similarity scale
and cooperation among proselfs (r = 0.39, p < 0.001).
The Methodological Objective
In support of H
3
, the distinct prediction of cooperation was
shown with computational language assessments but not with
numerical rating scales. The computational language assessment
of harmony in life also clearly supported the prediction in H
1
,
but this was not the case for the HILS. However, in relation to H
2
there were no significant correlations among the satisfaction with
life measures and cooperation (see Figure 1).
The Computational Language
Assessment-Based Plot
Figure 2 shows the statistically significant word responses
according to the type of open-ended question (x-axis) and to the
level of cooperation (y-axis). In regard to H
4
, the relationships
hypothesized in H
1
and H
2
were observed considering that there
were more words that were significantly more closely related to
high harmony in life that were also significantly related to a high
level of cooperation, as compared with high satisfaction with life.
That is, 10 words are significant in the right upper corner (see
legend; including peace, happiness, balance, harmony, and unity)
whereas there are 0 significant words in the right lower corner.
On the other side, there are only 2 words (fulfilled and annoyed)
related to overall satisfaction with life and high cooperation, but
4 words related to satisfaction with life and low cooperation
(including happy, proud, unhappy, and satisfied).
DISCUSSION
Well-Being and Cooperation Objective
We have demonstrated a clear link between subjective well-
being and cooperation. Specifically, the computational language
assessment of harmony in life yielded a moderately strong
significant positive correlation with degree of cooperation in

prosocials, while the computational language assessment of
overall satisfaction with life did not. This held true even
when controlling for all other studied well-being measures
(including the traditional numeric rating scales and the predicted
valence of the word responses), gender, age, and perceived
financial situation.
The word figures further support the importance of harmony
in life in relation to cooperation. The statistically different word
responses between the harmony in life and satisfaction with life
are consistent with previous research; for example, peaceful and
calm are related to harmony in life, and happy and fulfilled are
related to satisfaction with life (Kjell et al., 2019). Importantly,
the Cooperation-axis further supports that overall harmony in
life, but not overall satisfaction with life, is positively related
to cooperation, considering that words such as peace, balance,
harmony, and unity are related to both high harmony in life
and cooperation, whereas words such as happy, proud, and
satisfied are related to satisfaction with life responses and low
levels of cooperation.
Different conditions and situations that support and promote
cooperation have been extensively researched (see e.g., Calcott,
2008). Cooperation is a particularly integral part of human
society, where human cooperation can be attributed to well-
developed cognitive resources (Stevens and Hauser, 2004).

Kjell et al. Computational Language Assessments: Harmony and Cooperation
FIGURE 1 | Partial Spearman’s rho correlation (with 95% confidence interval)
between each well-being measure and cooperation. The data were controlled
for the three remaining well-being measures, language predicted valence,
perceived financial situation, gender, and age for the various groups. Only
H-SSS for prosocials was significant (r = 0.41; p < 0.001); n = 69 prosocials,
n = 59 proselfs. SSS, Semantic Similarity Scale; H, harmony; S, satisfaction;
HILS, Harmony in Life Scale; SWLS, Satisfaction with Life Scale. Note that the
n differs from Table 3 because partial correlation requires no missing values
on all variables.
However, previous research has particularly examined whether
certain emotions (e.g., Ketelaar and Au, 2003; de Hooge et al.,
2007; Nelissen et al., 2007; Kjell and Thompson, 2013) or positive
mood (Proto et al., 2019) lead to increased cooperation, and less
focus has been put on the cognitive component of subjective well-
being. To our knowledge, this is the first experiment that tests and
demonstrates an association between cooperation and harmony
in life measured as the cognitive component of subjective
well-being.
Considering the importance of cooperation for societies, we
believe that the current results warrant further research interest
to deepen the understanding of the link to harmony in life and
to satisfaction with life. The results may be seen as particularly
important for the subjective well-being literature because there
currently is a rather narrow understanding of well-being that
predominantly focuses on satisfaction with life. This relates to
Kjell’s (2011) concern that a one-sided satisfaction with life focus:
“Appears likely to encourage the individual to put
themselves and their expectations first rather than
allowing for an adaptive balance of both satisfaction and
balance/harmony. Furthermore, measuring satisfaction
while neglecting balance/harmony, might crucially relate to
the issue that one person’s satisfaction can result in another
person’s dissatisfaction.” (p. 260).
Thus, overall, the results give support to the concerns that an
overemphasized focus on satisfaction with life can be considered
to one-sidedly reflect self-regard and self-centeredness (e.g., see
Christopher, 1999; Kjell, 2011), and they suggest that harmony in
life is important in complementing satisfaction with life within
the subjective well-being approach (see also Kjell et al., 2016).
Prosocials and Proselfs
Whereas there was a positive correlation between harmony
semantic similarity scores and cooperation among prosocials
as expected; the results revealed a positive correlation between
disharmony semantic similarity scores and cooperation among
proselfs. That is, among proselfs higher levels of cooperation
was related to higher semantic similarity between their harmony
in life word-responses and the disharmony word norm (i.e., a
negative valenced word norm). This finding may perhaps be
compared with how inducing proselfs with guilt (i.e., a negative
valenced emotion) increases their cooperation (Ketelaar and Au,
2003; de Hooge et al., 2007). However, to further understand this
relationship among proselfs require further research.
The Methodological Objective
From a methodological perspective, this study shows that open-
ended, computational language assessments of well-being are
distinctly related to a theoretically relevant behavioral outcome,
whereas standard, closed-ended numerical rating scales are not.
As previously discussed, these differences are also discerned
in the word figures, where the rating scales method lack an
equivalent descriptive analytic method (since rating scales do not
allow for descriptive word responses).
To our knowledge this is the first research study that
supports the validity of self-reported computational language
assessments over traditional rating scales in relation to actual
behaviors. Research has, for example, shown that self-reported
computational language assessments demonstrate very high
convergence with rating scales (Kjell et al., 2021) and that
computational language assessments yield higher validity in
categorizing external stimuli, including facial expressions (Kjell
et al., 2019). There is also evidence that computational language
assessments based on individuals social media texts (rather than
question-based, prompted, self-reports) can predict personality
(Schwartz et al., 2013) and are correlated with depression in
medical records (Eichstaedt et al., 2018).
Thus, the results presented here add to the research
literature demonstrating the validity of computational language
assessments. We suggest that future research should attempt to
identify the boundary conditions of the computational language
assessments (e.g., identifying conditions when ratings scales may
have higher validity than computational language assessments
and where a combination might be preferred). It would also be
valuable to examine respondents preferences for the different
response formats. For example, which format do respondents

prefer in regard to how easy it is to use or how well they can
describe their mental states.
Limitations
The current study has some limitations. It examined only
a specific type of cooperation that was constrained to one
interaction with an “anonymous” person about money, and
participants only received the extreme amounts (i.e., all or
nothing). Future studies could also examine harmony versus
satisfaction in social dilemmas that, for example, include repeated
interactions concerning more aspects than just money. In
addition to replicating the current results, future research could
examine whether the cooperative link between well-being and
cooperation differs in different contexts and situations.
Buhrmester et al. (2011) demonstrated that using Mechanical
Turk to collect data produces comparable results as more
conventional and standard methods, while also ensuring good
generalisability. However, future studies could examine these
effects when participants are recruited from other, more social
contexts. Further, the analyses statistically controlled for several
factors, including perceived financial situation and other well-
being measures; however, to further our understanding of
the computational language assessments, future studies could
control for participants’ current emotional state as well as
personality traits. Lastly, the current study did not record the
time required to answer the different assessment methods.
Whereas Kjell et al. (2019) found that it took longer time for
participants to answer the open-ended word format than the
rating scales format when describing facial expressions; they also
found that only using one rather than ten descriptive words
when describing their own mental health produced reliable,
although somewhat less accurate, predictions. Future studies
could examine how many responses that are necessary while
preserving high validity and reliability, how long time each
method take to complete and whether respondents prefer one
assessment method over the other.
CONCLUSION
From a methodological perspective, the results support
the validity of computational language assessments, and
computational language assessments can distinctly reveal the
theoretically relevant behavioral outcome of cooperation within
a social dilemma game in relation to subjective well-being, while
traditional rating scales cannot. From a well-being perspective,
the results reveal a distinct behavioral difference between
harmony in life and satisfaction with life, with harmony in life
being to a higher degree related to cooperative behavior.
