The diversity advantage: An explanatory framework for personality traits

Why do human beings exhibit enduring personality differences, and to what extent are these differences shaped by biological and cultural evolution? Despite ongoing efforts, a consensus framework remains elusive. This paper introduces the Diversity Advantage Theory, partially shifting the focus from how personality impacts individuals to its influence within groups. Through an evolutionary lens, connections among personality, collective cognition, and group dynamics are explored, revealing that diversity in personality traits would tend to enhance collective intelligence and foster deliberation, mitigating group biases. The framework proposes that biologically evolved psychological mechanisms underlying personality, including individual niche-finding, adapt and conform to culturally evolving heuristic personality traits. This co-evolution stabilized the Big Few personality traits in western, educated, industrialized, rich, and democratic (WEIRD) societies, addressing recurring group challenges related to engagement, closure, task, risk, and change. The Diversity Advantage Theory offers a novel explanatory framework for stable personality traits, aligning with biology and testable in contemporary group contexts. At least three novel perspectives are introduced: (1) personality trait dimensions have emerged, in part, to establish normative behavior for functional group processes; (2) normative diversity along trait dimensions enhances collective intelligence; and (3) such diversity should also promote deliberation, mitigate group biases, and improve group decision-making.

Drought response in herbaceous plants: A test of the integrated framework of plant form and function

Abstract Multidimensional trait frameworks are increasingly used to understand plant strategies for growth and survival. However, it is unclear if frameworks developed at a global level can be applied in local communities and how well these frameworks—based largely on plant morphological traits—align with plant physiology and response to stress. We tested the ability of an integrated framework of plant form and function to characterise seedling trait variation and drought response among 22 grasses and forbs common in a semi‐arid grassland. We measured above‐ground and below‐ground traits, and survival to explore how drought response is linked to three trait dimensions (resource conservation, microbial collaboration, and plant size) associated with the framework as well as non‐morphological dimensions (e.g. physiological traits) that are under‐represented in global trait frameworks. We found support for three globally‐recognised axes representing trade‐offs in strategies associated with tissue investment (leaf nitrogen, leaf mass per area, root tissue density), below‐ground resource uptake (root diameter, specific root length), and size (shoot mass). However, in contrast to global patterns, above‐ground and below‐ground resource conservation gradients were oppositely aligned: root tissue density was positively correlated with leaf N rather than leaf mass per area. This likely reflects different investment strategies of annual and perennial herbaceous species, as fast‐growing annual species invested in lower density roots and less nitrogen‐rich leaves to maximise plant‐level carbon assimilation. Species with longer drought survival minimised water loss through small above‐ground size and low leaf‐level transpiration rates, and drought survival was best predicted by a principal component axis representing plant size. Contrary to our expectations, drought survival in seedlings did not align with the conservation or collaboration axes suggesting that seedlings with different functional strategies can achieve similar drought survival, as long as they minimise water loss. Our results also show that within local communities, expected trait relationships could be decoupled as some plant groups achieve similar performance through different trait combinations. The effectiveness of species mean trait values in predicting drought response highlights the value of trait‐based methods as a versatile tool for understanding ecological processes locally across various ecosystems.

Do millennials’ personalities and smartphone use result in materialism? The mediating role of addiction

PurposeThis paper aims to use the five-factor model’s (FFM: emotional instability, introversion, openness to experience, agreeableness and conscientiousness) personality traits and the need for arousal to explain millennials’ habitual and addictive smartphone use and resultant materialistic inclinations. The study also test the mediating role of addictive use in the relationship between habitual use and materialism.Design/methodology/approachParticipants’ self-reported data (n = 705) from a sample of millennials were gathered using a cross-sectional survey approach conducted in Malaysia and studied using structural equation modelling with partial least squares (PLS-SEM).FindingsThe results discover that emotional instability, openness to experience, agreeableness and need for arousal have a significant influence on habitual smartphone use. Conversely, introversion and conscientiousness have no significant impact on habitual use. Fascinatingly, millennials’ habitual use positively influences their materialism. Furthermore, addictive smartphone use positively affects materialism and mediates the relationship between habitual use and materialism.Originality/valueThe FFM, a prominent personality trait model, has been used in numerous studies to predict usage intention. However, the particular dimension of the FFM personality traits that drive habitual and addictive smartphone use to trigger materialistic tendencies among millennials needs to be exposed in an emerging market context. The results emphasise the need to consider this demographic’s personalities when attempting to comprehend how habitual use and materialism occur. This study also provides practitioners with helpful information in creating targeted interventions to encourage healthy smartphone use behaviours and reduce possible adverse effects related to addictive smartphone use and materialistic attitudes.

Parenting Characteristics and Callous-Unemotional Traits in Children Aged 0-6 Years: A Systematic Narrative Review.

There has been a growing interest in research examining the relationship between parenting and child callous-unemotional (CU) traits, particularly in early childhood. This study reviewed evidence from studies that investigated the relationship between parenting characteristics (e.g., caregiving beliefs, attitudes, behaviour or quality, or parental mental health) and callous-unemotional traits in children aged 0 to 6years. A systematic search conducted according to PRISMA guidelines yielded 27 peer-reviewed articles. Analysis of the included articles suggested that there was strong evidence to support links between child CU traits and parenting characteristics (particularly, parental feelings about their child, warm parenting, and harsh/ inconsistent parenting). Taken together, the results of this review demonstrate the links between both positive and negative dimensions of parenting and CU traits in early childhood; however, mixed findings highlight the need for further research.

‘Warming up’ to populist leaders: A comparative analysis of Argentina and Spain

What makes populist leaders, responsible for many episodes of democratic backsliding, especially appealing to a significant part of the electorate? In the following pages we argue that the effect of perceptions regarding leaders’ ‘warmth’ causes them to be perceived as having good intentions toward and even being part of ‘the people,’ resulting in a more positive overall evaluation among citizens with more critical views of democratic representativeness (external political efficacy). We test this hypothesis in two very different political systems, Argentina and Spain, using data from original surveys that contain batteries of questions on warmth and competence trait dimensions for multiple leaders in both countries. The results show that while perceptions of traits along both warmth and competence dimensions are important for the evaluation of all leaders in democratic systems, the interactive effect between external political efficacy and perceptions of warmth is important for explaining more positive evaluations of populist leaders.

The personal cost of psychopathy: Impacts of triarchic psychopathy traits on impairment, internalizing, and life satisfaction

Although psychopathic traits have long been acknowledged as a public health concern, a growing body of evidence suggests there is a significant personal cost to living with psychopathy. However, much of the current literature on psychopathy impairment appears mixed in findings, varying by the traits examined and measured outcomes. The current paper aims to contribute to this field of research by examining how a triarchic model of psychopathy relates to a wide variety of potential consequences, including impairment, personality functioning, interpersonal functioning, internalizing, and perceived quality of life. Through two studies utilizing the Triarchic psychopathy model in undergraduate samples, significant psychopathy impairment was identified. Broadly, disinhibition was related to the most significant impairments across functioning domains. Boldness was more variable and elicited both positive (e.g., higher quality of life, lower self-harm) and negative (impairments in empathy and intimacy) outcomes. Meanness was primarily related to interpersonal difficulties; however, differences in measuring meanness led to different findings on its connection to personality functioning. By better understanding the consequences of psychopathy and how they vary by dimensional traits, interventions can be better tailored to alleviate both individual and societal suffering.

The mediating effect of perceived stress on the relationship between big five personality traits and suboptimal health status in Chinese population: a nationwide survey in the framework of predictive, preventive, and personalized medicine.

The effects of psychological factors on suboptimal health status (SHS) have been widely described; however, mechanisms behind the complex relationships among the Big Five personality traits and SHS are unclear. Identifying people with specific traits who are susceptible to SHS will help improve life quality and reduce the chronic disease burden under the framework of predictive, preventive, and personalized medicine (PPPM/3PM). This study investigated the relationships among personality traits and SHS. It also explored whether perceived stress plays a mediating role in SHS development. A nationwide cross-sectional survey based on multistage random sampling was conducted in 148 cities in China between June 20 and August 31, 2022. Personality traits, perceived stress, and SHS were evaluated using the Big Five Inventory-10 (BFI-10), the 4-item Perceived Stress Scale (PSS-4), and the Short-Form Suboptimal Health Status Questionnaire (SHSQ-SF), respectively. Pearson's correlation analysis was employed to examine the associations between personality traits, perceived stress, and SHS. Structural equation modeling (SEM) was used to discern the mediating role of perceived stress in the relationships among personality traits and SHS. A total of 22,897 participants were enrolled in this study, among whom the prevalence of SHS was 52.9%. SHS was negatively correlated with three trait dimensions (i.e., extraversion, agreeableness, and conscientiousness) but positively correlated with neuroticism. Meanwhile, stress was negatively correlated with extraversion, agreeableness, conscientiousness, and openness, whereas it was positively correlated with neuroticism. The SEM results showed that, when adjusting for covariates (i.e., gender, age, BMI, educational level, current residence, marital status, and occupational status), higher agreeableness (β = - 0.049, P < 0.001) and conscientiousness (β = - 0.103, P < 0.001) led to lower SHS prevalence, higher neuroticism (β = 0.130, P < 0.001), and openness (β = 0.026, P < 0.001) caused SHS to be more prevalent. Perceived stress played a partial mediating role in the relationships among personality traits and SHS, respectively, contributing 41.3%, 35.9%, and 32.5% to the total effects of agreeableness, conscientiousness, and neuroticism on SHS. Additionally, the mediating impact of stress was significant even though extraversion had no direct effect on SHS. This study revealed a high prevalence of SHS in Chinese residents. Personality traits significantly influenced SHS rates, which perceived stress tended to mediate. From a PPPM perspective, early screening and targeted intervention for people with neuroticism (as well as stress alleviation) might contribute to health enhancement and chronic disease prevention.

Psychopathy and gaze cueing

Background and objectivesPsychopathic traits – and especially callous affective features – have been linked to altered processing of others’ emotional expressions, and to reduced attention to the eyes. Despite the importance of gaze cueing (i.e., the tendency to orient attention toward where someone else is looking) for social functioning, few studies have investigated relationships between psychopathic traits and gaze cueing, and whether facial emotional expression influence these relationships, obtaining mixed results. To address this gap, the present study aimed to evaluate associations between psychopathic traits and gaze cueing for emotional and neutral expressions. Methods65 non-clinical male participants (Mage = 27.3 years) completed two self-report measures of psychopathy and performed laboratory tasks to assess gaze-cueing for emotional vs. neutral faces and an arrow-cueing task as a comparison. ResultsLinear mixed models showed no significant associations of emotional (versus neutral) expressions, or psychopathy trait dimensions, with either gaze cueing or arrow cueing. LimitationsReliance on a convenience sample of non-clinical men, assessed with self-reports measures of psychopathy, and using static emotional stimuli limit the generalizability of our findings. ConclusionsFindings suggest that psychopathic traits are not associated with individual differences in following others’ gaze to direct attention, and that there was no advantage for affective relative to neutral expressions.

Trait dimensions of abiotic stress tolerance in woody plants of the Northern Hemisphere

AbstractAimTrade‐offs among tolerances to different abiotic stressors limit polytolerance in woody plants. However, the general trait syndromes that underlie large‐scale tolerance patterns of woody plants remain controversial. Here, we tested if the leading trait dimensions that define the global spectrum of plant form and function capture the underlying trait trade‐offs limiting woody plant polytolerance.LocationNorthern Hemisphere.Time PeriodPresent.Major Taxa StudiedWoody plants.MethodsWe used a dataset of 779 species to link the trait dimensions defining the global spectrum of plant form and function with two dimensions summarizing tolerance syndromes to drought, shade, cold and waterlogging. Stress tolerance dimensions were a trade‐off between drought and cold/waterlogging tolerance strategies, and a shade tolerance spectrum. Relationships among trait and stress tolerance dimensions were evaluated using general additive models separately for deciduous and evergreen angiosperms, and evergreen gymnosperms.ResultsDrought‐tolerant angiosperms showed greater specific stem density (SSD) and seed mass (SM), and lower specific leaf area (SLA) and leaf nitrogen content per mass (LN), compared to the cold/waterlogging‐tolerant species. Shade‐tolerant angiosperms displayed greater SSD and SM and lower SLA and LN compared to intolerant angiosperms. Highly contrasting trait adaptations also distinguished drought‐ (greater SSD, SM and lower SLA, LN) from shade‐tolerant evergreen gymnosperms.Main ConclusionsThe ‘SSD–SM’ and the ‘SLA–LN’ dimensions mainly distinguish cold or drought‐tolerant woody angiosperms and shade‐ or drought‐tolerant gymnosperms. Our results also support a conservative trait strategy for shade‐tolerant compared to shade‐intolerant species, with some differences between plant functional types probably due to contrasting leaf lifespans. Overall, our findings identify some leading functional constraints on polytolerance in woody plants and provide a framework to integrate additional trait dimensions to fully elucidate such constraints.

Exaggerating differences back and forth: Two levels of intergroup accentuation.

Social perceivers tend to exaggerate existing differences between groups, a phenomenon known as intergroup accentuation. In two preregistered experiments, we tested the hypothesis that accentuation originates in the initial learning of information about a novel group. In both experiments, perceivers exaggerated differences between two fictitious social groups that differed probabilistically in two dimensional traits. As hypothesized, accentuation was stronger for the group encountered second, confirming that accentuation originates partly in processes operating during the acquisition of group information. However, accentuation was also robust for the group encountered first, suggesting that it also occurs 'backward' even when group learning was unbiased. We discuss implications for stereotype formation generally and the perception of social minorities and out-groups specifically. As these groups are often encountered second in social reality, stereotypes of them might be particularly polarized.

The structure of aggressive personality.

We sought to factor analyze a broad array of aggression measures to identify a comprehensive, coherent factor structure for this construct. Measures and models of trait aggression have multiplied to the point of incoherence. In Study 1, a diverse sample of 922 undergraduates completed a battery of items acquired from 42 self-report aggression questionnaires. In Study 2, we administered a curated item pool to another diverse sample of 1447 undergraduates, alongside criterion measures. We curated an initial item pool of 734 items down to 289 items that exhibited sufficient variability, were not redundant with other items, and possessed strong loadings onto a central 'trait aggression' factor. These remaining items were best characterized by a six-factor structure, which captured relational, angry, violent, retaliatory, intimate partner, and alcohol forms of aggression. We estimated their hierarchical structure, correlations with their original aggression scales, Five Factor Model trait dimensions, impulsivity facets, and found them to be robust to gender composition and the inclusion of alcohol-naive and intimate-partner-naive participants. This factor structure mostly supported widely-accepted models of aggressive personality that focus on its overt and relational forms and reactive functions, though proactive aggression only loosely emerged as a distinct entity. We retained the final items as the Comprehensive Aggression Scale (CAS).

The Effect of Dark Personality Traits on The Tendency of Accountants Towards Accounting Fraud

It is known that the personality traits of professional accountants affect their attitudes towards fraud and unethical behavior. In this study, it is aimed to examine the effect of dark triad personality traits of accounting professionals on their tendency to commit accounting fraud. The research is important in terms of bringing a psychology and accounting-based study to the literature of our country, which is widely seen in the international literature. Data were collected from 307 professional accountants registered in the Chamber of Certified Public Accountants of Balıkesir through the questionnaire developed within the scope of the research. Obtained data were analyzed by using structural equation model through IBM SPSS 25 and AMOS programs. As a result of the research, it has been concluded that the psychopathy and Machiavellian dimensions of the dark personality traits of the professions affect the internal and external motivations of their tendency to commit accounting fraud, but the narcissism dimension from the dark personality traits does not influence the tendency of accounting professionals to commit fraud. By identifying individuals with dark triad personality traits, it is possible to reduce negative situations in the business environment, tendencies towards accounting fraud, unethical behaviors and actions.

Life history strategies of soil bacterial communities across global terrestrial biomes.

The life history strategies of soil microbes determine their metabolic potential and their response to environmental changes. Yet these strategies remain poorly understood. Here we use shotgun metagenomes from terrestrial biomes to characterize overarching covariations of the genomic traits that capture dominant life history strategies in bacterial communities. The emerging patterns show a triangle of life history strategies shaped by two trait dimensions, supporting previous theoretical and isolate-based studies. The first dimension ranges from streamlined genomes with simple metabolisms to larger genomes and expanded metabolic capacities. As metabolic capacities expand, bacterial communities increasingly differentiate along a second dimension that reflects a trade-off between increasing capacities for environmental responsiveness or for nutrient recycling. Random forest analyses show that soil pH, C:N ratio and precipitation patterns together drive the dominant life history strategy of soil bacterial communities and their biogeographic distribution. Our findings provide a trait-based framework to compare life history strategies of soil bacteria.

Morality in middle childhood: the role of callous-unemotional traits and emotion regulation skills

BackgroundThe development of morality is vital for fostering prosocial behavior and enhancing both individual and societal well-being. Clarifying what contextual and individual factors play a role in moral processes during childhood can contribute to our understanding of the development of morality. Given the previous acknowledgment of importance, yet lack of existing empirical findings, the study focused on the significance of callous-unemotional traits (i.e., an affective-interpersonal personality trait, related to psychopathy in adulthood) and emotion regulation (i.e., an essential part of socio-emotional competence, and a transdiagnostic factor in the development of psychopathology) for moral emotions and cognitions during middle childhood. The concrete aim was to examine direct and indirect effects of callous-unemotional trait dimensions (callousness, uncaring, unemotionality) onto immoral emotional attribution (i.e., feeling good after immoral decisions) and admissibility of immoral actions (i.e., evaluating immoral actions as being okay) via emotion regulation skills.MethodsA cross-sectional study was conducted with 194 children attending Grades 1 to 4, and their primary caregivers. The children completed the Inventory of Callous-Unemotional Traits and caregivers completed the Emotion Regulation Checklist. The children were also presented with a set of moral dilemma vignettes, and asked about the emotions of protagonists who acted immoral, and the admissibility of their actions.ResultsPath-model analysis revealed (1) negative direct effects of emotion regulation skills onto immoral emotional attribution and admissibility of immoral actions, (2) positive direct effects of the dimensions callousness and uncaring onto immoral emotional attribution and admissibility of immoral actions, and (3) negative direct effects of dimensions callousness and uncaring onto emotion regulation skills. Indirect effects, indicating that emotion regulation skills mediate the association between the callous-unemotional trait dimensions and morality, were also found.ConclusionThe findings address a knowledge gap and indicate that emotion regulation skills, callousness, and uncaring play an important role in morality in middle childhood and should be included in frameworks of moral decision-making and development.

Impacts of psychopathic traits dimensions on the development of indirect aggression from childhood to adolescence.

Children who show elevated levels of indirect aggression (IA) from childhood to adolescence are at increased risks of experiencing detrimental outcomes. Some studies suggest that psychopathic traits could act as a predisposing vulnerability in the development of IA, but the contributions of all three dimensions of psychopathic traits in explaining developmental trajectories of IA from childhood to adolescence remain unclear. This study aimed to determine if the three dimensions of psychopathic traits during childhood (i.e., callous-unemotional, narcissism-grandiosity, and impulsivity-irresponsibility at 6-9 years old) increase the risk of following a high IA trajectory across preadolescence, and whether sex moderated these associations. Participants were 744 children (47% girls; 93% born in Quebec, Canada, and over 50% from low socioeconomic backgrounds) assessed annually over 5 years. Approximately half of them (n = 370; 40.3% girls) were referred to school-based services for conduct problems (CP) at study intake. Latent class growth analyses revealed four developmental trajectories of IA, which were regressed on psychopathic traits dimensions using a three-step approach. After adjusting for demographic confounders, CP, and other dimensions of psychopathic traits, only narcissism-grandiosity traits significantly predicted memberships to a high and stable trajectory of IA use. The associations between the other dimensions of psychopathic traits and IA trajectories were not significant when considering confounders. No moderating effects by child sex were observed. These results suggest that narcissism-grandiosity traits could be of use for clinicians aiming to detect children most at risk of showing high and persistent levels of IA.

What drives social co-creation in tourism? An empirical study

Purpose As competition in the industry intensifies, companies must use market-oriented approaches to gain competitive superiority; one of the approaches that can lead to the success of companies in the competitive market is to undertake social co-creation with the help of customers. Although the use of social media for the development of social interactions has expanded, very little attention has been paid to how the concept of social co-creation is formed on social media by users. Therefore, this study aims to investigate the effect of personality traits and website quality on social co-creation, with the mediating role of trust in tourism websites. Design/methodology/approach This research, in terms of purpose, is practical, and in terms of information collection, it is a descriptive survey. The research statistical population is all users of active tourism sites in Iran. The sampling method is non-probability and available sampling. The questionnaire was designed based on the Likert scale and was distributed electronically among the statistical sample. After collecting and reviewing the questionnaires, 203 were used for analysis. The data analysis method in this study is hierarchical multiple regression. Findings The results indicated that personality traits and website quality are correlated with trust and social co-creation. The dimensions of website quality, including quality of information, quality of system and quality of service on tourism websites, have considerable and positive effects on trust. Also, all dimensions of the personality traits, except extraversion and neuroticism, have a considerable and positive effect on trust. Moreover, the correlation between trust and social co-creation is positive. Originality/value According to the review of the digital marketing literature, some researchers examined the influential factors in co-creation, but there is little research about how the interaction of these three concepts (personality traits, website quality and trust) enhances co-creation. This study contributes to the existing literature with empirical evidence of how personality traits and website quality influence co-creation by mediating the role of trust.

Quasi-neutral dynamics in a coinfection system with N strains and asymmetries along multiple traits.

Understanding the interplay of different traits in a co-infection system with multiple strains has many applications in ecology and epidemiology. Because of high dimensionality and complex feedback between traits manifested in infection and co-infection, the study of such systems remains a challenge. In the case where strains are similar (quasi-neutrality assumption), we can model trait variation as perturbations in parameters, which simplifies analysis. Here, we apply singular perturbation theory to many strain parameters simultaneously and advance analytically to obtain their explicit collective dynamics. We consider and study such a quasi-neutral model of susceptible-infected-susceptible (SIS) dynamics among N strains, which vary in 5 fitness dimensions: transmissibility, clearance rate of single- and co-infection, transmission probability from mixed coinfection, and co-colonization vulnerability factors encompassing cooperation and competition. This quasi-neutral system is analyzed with a singular perturbation method through an appropriate slow-fast decomposition. The fast dynamics correspond to the embedded neutral system, while the slow dynamics are governed by an N-dimensional replicator equation, describing the time evolution of strain frequencies. The coefficients of this replicator system are pairwise invasion fitnesses between strains, which, in our model, are an explicit weighted sum of pairwise asymmetries along all trait dimensions. Remarkably these weights depend only on the parameters of the neutral system. Such model reduction highlights the centrality of the neutral system for dynamics at the edge of neutrality and exposes critical features for the maintenance of diversity.

Big Five Traits of Sir Walter Elliot in Jane Austen’s “Persuasion”

Big five personality traits known as five factor model (FFM) is a set of five broad trait dimensions or domains to describe the one’s traits of personality. In this research, the researcher examined big five traits’ aspects from Sir Walter Elliot on the novel of “persuasion” Jane Austen, using McCrae theory. The researcher also used documentation techniques and qualitative methods to collect data on the peripheral characters in this movie. The researcher managed to find 8 data: The data found were Conscientiousness (1), Extroversion (3), Agreeableness (2), Shallow Neuroticism (1), Openness to Experience (1) in Sir Walter Elliot big five traits. Extroversion gives big impact to his personalities compared the other aspects

Responses of economic and anatomical leaf traits to soil fertility factors in eight coexisting broadleaf species in temperate forests

The multidimensionality of leaf traits allows plants to have diverse survival strategies to adapt to complex living environments. Whether the anatomical traits of leaves are associated with leaf economic traits and which group of traits are more strongly correlated with soil fertility factors remains unclear. We measured four leaf economic traits, four anatomical traits, and five soil fertility factors of eight coexisting broadleaf species distributed in mixed broadleaved-Korean pine (Pinus koraiensis) forests located in Northeast China. Results show a strong interdependence between economic and anatomical traits (p &amp;lt; 0.05). The range of variation between economic and anatomical traits were almost equal, but the causes of variation were different. Specific leaf area was positively correlated with the abaxial epidermis, negatively correlated with the ratio of spongy tissue to leaf thickness (ST/LT), and not correlated with adaxial epidermis. Leaf dry matter content was negatively correlated with the abaxial epidermis and adaxial epidermis, positively correlated with ST/LT. Specific leaf area, palisade tissue, and ST/LT showed stronger correlation with soil fertility factors than other traits. Soil fertility factors dominating trait variation were dependent upon the trait. Our results suggest anatomical traits can be considered in economic trait dimension. The coupled relationship between anatomical and economic traits is potentially a cost-effective adaptation strategy for species to improve efficiency in resource utilization. Our results provide evidence for the complex soil-trait relationship and suggest that future studies should emphasize the role of anatomic traits in predicting soil fertility changes.

Relationship between context‐free/in‐context spatial color preferences and color constructs: The extraversion personality trait dimension

AbstractPersonality traits are considered the primary determinants of emotional and behavioral patterns of individuals within the built environment, influencing the experience of architectural space over their cognitive representation. Specifically, the dimension of extraversion within an individual's personality holds considerable predictive value in determining their attitudes toward the environment. Consequently, this study aims to investigate the influence of personality traits on color preference by comparing preferences for context‐free color samples and in‐context spatial colors among individuals exhibiting varying levels of extraversion. It also aims to ascertain the most accurate color‐construct scale for delineating individuals' preferences for in‐context spatial color. The study employed the International Personality Item Pool (IPIP) representation of lexical factor markers for the Big‐Five structure. For the study, 11 colors, referred to as basic color terms, were selected as stimuli. Data on color preference were obtained through a rank order test for 11 context‐free color samples and 11 virtual images of in‐context spatial colors, as well as ratings of in‐context spatial colors based on 14 color‐construct scales. Findings reveal the relationship between extraversion personality trait and color preferences, revealing distinct patterns between context‐free and in‐context color preferences. They also suggest the possibility of divergent preferences for in‐context spatial colors among individuals with varying levels of extraversion, with certain colors eliciting significantly different ratings on color‐construct scales. The study's findings shed light on the importance of personality traits in predicting the relationship between architectural spaces and colors, depending on individuals' personalities, particularly within design disciplines such as interior architecture.
