Like all behaviour, personality traits are substantially heritable, but their genetic background is poorly understood. Investigating traits’ genetic background could help explain disparities in health and other life outcomes they contribute to. We describe two cohorts of the Estonian Biobank for whom, besides self- and informant-rated personality t...
The study aims to disentangle the effects of human development and gender egalitarianism on the differences between men and women in personality traits across various countries. It examined this phenomenon in four countries with differing levels of human development and gender egalitarianism: Burkina Faso (low human development/low gender egalitari...
Despite numerous meta-analyses, the true extent to which life satisfaction reflects personality traits has remained unclear due to overreliance on a single method to assess both and insufficient attention to construct overlaps. Using data from three samples tested in different languages (Estonian, N = 20,886; Russian, N = 768; English, N = 600), we...
As COVID-19 vaccines’ accessibility has grown, so has the role of personal choice in vaccination, and not everybody is willing to vaccinate. Exploring personality traits’ associations with vaccination could highlight some person-level drivers of, and barriers to, vaccination. We used self- and informant-ratings of the Five-Factor Model domains and...
Like all behaviour, personality traits are substantially heritable, but their genetic background is poorly understood. Investigating traits’ genetic background could help explain disparities in health and other life outcomes that the traits likely contribute to. We describe two cohorts of the Estonian Biobank for whom, besides self- and informant-r...
Affective aspects of a stimulus can be processed rapidly and before cognitive attribution, acting much earlier for verbal stimuli than previously considered. Aimed for specific mechanisms, event-related brain potentials (ERPs), expressed in facial expressions or word meaning and evoked by six basic emotions - anger, disgust, fear, happy, sad, and s...
Culture-and-personality studies were central to social science in the early 20th century and have recently been revived (as personality-and-culture studies) by trait and cross-cultural psychologists. In this article we comment on conceptual issues, including the nature of traits and the nature of the personality-and-culture relationship, and we des...

Little research has examined age differences by using more than one source of information. We compared age differences in Five-Factor Model (FFM) facets and nuances in self-reports and ratings by knowledgeable informants using samples from three countries (Estonia, Germany, and the Czech Republic; N=5,624). We hypothesized that age differences woul...
The ability to evaluate the number of elements in a set—numerosity—without symbolic representation is a form of primitive perceptual intelligence. A simple binomial model was proposed to explain how observers discriminate the numerical proportion between two sets of elements distinct in color or orientation (Raidvee et al., 2017, Attention Percepti...
Visual perception is capable of pooling multiple local orientation signals into a single more accurate summary orientation. However, there is still a lack of systematic inquiry into which summary statistics are implemented in that process. Here, the task was to recognize in which direction, clockwise or counter-clockwise, the mean orientation of a...
There are considerable individual differences in remembering past episodes. The current study aimed to examine the link between episodic memory reliving and the Five-Factor Model personality traits. Altogether 422 participants (67% women) described an autobiographical episode and rated the vividness and clarity of that recollection. Next, they asse...
This article presents an overview of the current state of knowledge in personality judgment research. We discuss accuracy and bias in personality judgments, including types of inter-rater agreement and elements of criteria used to determine levels of agreement and accuracy. We then address 1) the words and phrases that people use to describe one an...
This study mapped the personality and genetics of risky excitement-seekers focusing on skydiving behavior. We compared 298 skydivers to 298 demographically matched controls across the NEO Personality Inventory-3 domains, facets, and 240 items. The most significant item-level effects were aggregated into a poly-item score of skydiving-associated per...
Introduction
Diurnal preferences have been linked to personality but often with mixed results. The present study examines the relationships between sleep timing (chronotype), diurnal preferences and the Five‐Factor Model of personality traits at the phenotypic and genetic level.
Methods
Self‐ and informant‐reports of the NEO Personality Inventory‐...

The occupancy model (OM) was proposed to explain how the spatial arrangement of dots in sparse random patterns affects their perceived numerosity. The model’s central thesis maintained that each dot seemingly fills or occupies its surrounding area within a fixed radius ro and the total area collectively occupied by all the dots determines their app...
People differ in their sleep timings that are often referred to as a chronotype and can be operationalized as mid-sleep (midpoint between sleep onset and wake-up). The aims of the present studies were to examine intraindividual variability and longer-term temporal stability of mid-sleep on free and workdays, while also considering the effect of age...
In ensemble displays, two principal factors determine the precision with which the mean value of some perceptual attribute, such as size and orientation, can be discriminated: inefficiency and representational noise of each element. Inefficiency is mainly caused by biased inference, or by inattentional (feature) blindness (i.e., some elements or th...
This article presents an overview of the current state of knowledge in personality judgment research. We address (1) the words and phrases that people use to describe one another and themselves, (2) research in the “variable-centered” tradition, which investigates judgments of targets by perceivers on single traits, and (3) research investigating j...
Age differences in personality traits can inform us on the magnitude and qualities of personality development and describing them accurately is therefore of utmost importance. Little research yet has examined age differences by combining more than one source of information, despite many psychologists knowing that any one assessment method is prone...
The disciplinary profiles of the mean citation rates across 22 research areas were analyzed for 107 countries/territories that published at least 3,000 papers that exceeded the entrance thresholds for the Essential Science Indicators (ESI; Clarivate Analytics) during the period from January 1, 2009 to December 31, 2019. The matrix of pairwise diffe...
It has been repeatedly demonstrated that economic affluence is one of the main predictors of the scientific wealth of nations. Yet, the link is not as straightforward as is often presented. First, only a limited set of relatively affluent countries is usually studied. Second, there are differences between equally rich countries in their scientific...
In this age of data visualization, it is important to understand our perception of the symbols that are used. For example, does the perceived size of a disc correspond most closely to its area, diameter, circumference, or some other measure? When multiple items are present, this becomes a question of ensemble perception. Here, we compare observers’...
Culture is well recognized as an important basis for understanding psychological processes and behavior. Culturally informed research in psychology continues to supplement and challenge traditional knowledge in mainstream psychology in many ways, making culture a major topic of relevance for students and professionals in all areas of psychology. Th...
Personality researchers often supplement or substitute self-reports with ratings from knowledgeable informants, at least implicitly assuming that the same constructs are measured regardless of the source of ratings. However, measurement invariance (MI) of personality constructs across these rating types has rarely been empirically tested. Here, thi...
Humans modify their facial expressions in order to communicate their internal states and sometimes to mislead observers regarding their true emotional states. Evidence in experimental psychology shows that discriminative facial responses are short and subtle. This suggests that such behavior would be easier to distinguish when captured in high reso...
Participants (N = 10,672 with the mean age of 20.7 years) of the Russian Character and Personality Survey (RCPS), involving 40 universities or colleges from across the Russian Federation, rated their happiness and satisfaction with life; the ratings were combined into an index of subjective well-being (SWB). Using the National Character Survey (NCS...
Objectives
We tested predictions about the structure and magnitude of method biases in single‐source personality trait assessments. We expected a large number of distinct biases that would parallel the observed structure of traits, at both facet and item levels.
Method
We analyzed multi‐method ratings on the Estonian NEO Personality Inventory‐3 in...
Objective

Design
Prospective cohort study.
Setting
The Estonian Biobank of the Estonian Genome Centre, University of Tartu.
Participants
814 women a...
Emotion recognition has a key role in affective computing. Recently, fine-grained emotion analysis, such as compound facial expression of emotions, has attracted high interest of researchers working on affective computing. A compound facial emotion includes dominant and complementary emotions (e.g. happily-disgusted, sadly-fearful), which is more d...
It is widely accepted that the Five Factor Model (FFM) is a satisfactory description of the pattern of covariations among personality traits, which supposedly fits, more or less adequately, every individual. As an amendment to the FFM, we propose that the customary five-factor structure is only a near-universal, because it does not fit all individu...
The main aim of the current study was to examine the role of co-occurring emotions and their interactive effects with the Big Five personality traits in anger expression. Everyday anger expression (“anger-in” and “anger-out” behavior) was studied with the experience-sampling method in a group of 110 participants for 14 consecutive days on 7 random...
Only sufficient economic wealth can produce science with the highest quality. However, there is room for many intervening factors, which can moderate the process of how money invested into research transforms into a bibliometrically measurable outcome. In this paper, based on the latest update of the Essential Science Indicators (ESI), covering the...
We analyze the results of the 2017 ChaLearn Looking at People Challenge at ICCV. The challenge comprised three tracks: (1) large-scale isolated (2) continuous gesture recognition, and (3) real versus fake expressed emotions tracks. It is the second round for both gesture recognition challenges, which were held first in the context of the ICPR 2016...
Humans modify facial expressions in order to mislead observers regarding their true emotional states. Being able to recognize the authenticity of emotional displays is notoriously difficult for human observers. Evidence in experimental psychology shows that discriminative facial responses are short and subtle. This suggests that such behavior would...
Heritable variance in psychological traits may reflect genetic and biological processes that are not necessarily specific to these particular traits but pertain to a broader range of phenotypes. We tested the possibility that Five-Factor Model personality domains and their 30 facets, as rated by people themselves and their knowledgeable informants,...

However, measurement invariance (MI) of personality constructs across these rating types has rarely been empirically tested. Here, thi...
Researchers seem to believe that accepting the reality of personality traits inevitably leads to a dogma about the incredible complexity of these traits and their judgment. This paper challenges this thesis and its assertion that the accuracy of personality judgment can only be achieved when a "good target" or a "good trait" is being judged using "...

Previous studies have documented links between sub-clinical narcissism and the active pursuit of short-term mating strategies (e.g., unrestricted sociosexuality, marital infidelity, mate poaching). Nearly all of these investigations have relied solely on samples from Western cultures. In the current study, responses from a cross-cultural survey of...
The Revised NEO Personality Inventory (NEO-PI-R) and its latest version, the NEO-PI-3, were designed to measure 30 distinctive personality traits, which are grouped into Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness domains. The mean self-rated NEO-PI-R scores for 30 subscales have been reported for 36 countries or cultu...

According to a dominant view, Emil Kraepelin (1856–1926) was the founder of modern psychiatry, but his contribution to the history of experimental psychology was insignificant. This interpretation contradicts Kraepelin’s own view during his stay in Tartu (1886–1891) because at that time he was more interested in psychology than in his not very sati...
In order to commemorate Kraepelin’s 160th birthdate and the 130th year from his first professorship, a conference “Emil Kraepelin 160/130” was held in the same Aula of the University of Tartu where 130 years earlier Kraepelin expressed his views about the relationship between psychiatric illnesses and brain functions. This special issue is composed...
Objective:
Our study aims to estimate the proportion of the phenotypic variance of Neuroticism and its facet scales that can be attributed to common SNPs in two adult populations from Estonia (EGCUT; N = 3,292) and the Netherlands (Lifelines; N = 13,383).
Method:
Genomic-Relatedness-Matrix Restricted Maximum Likelihood (GREML) using Genome-wide...
The use of reliability estimates is increasingly scrutinized as scholars become more aware that test–retest stability and self–other agreement provide a better approximation of the theoretical and practical usefulness of an instrument than its internal reliability. In this study, we investigate item characteristics that potentially impact single-it...
Spearman’s hypothesis tested at the level of items states that differences between ethnic groups on the items of an IQ test are a function of the g loadings of these items, such that there are small differences between ethnic groups on items with low g loadings and large differences between ethnic groups on items with high g loadings; this has been...
Observers discriminated the numerical proportion of two sets of elements (N = 9, 13, 33, and 65) that differed either by color or orientation. According to the standard Thurstonian approach, the accuracy of proportion discrimination is determined by irreducible noise in the nervous system that stochastically transforms the number of presented visua...
Spearman's hypothesis tested at the level of items states that differences between ethnic groups on the items of an IQ test are a function of the g loadings of these items, such that there are small differences between ethnic groups on items with low g loadings and large differences between ethnic groups on items with high g loadings, and it has be...
Agreement between the self and other rated personality profiles was studied in two samples involving 11,096 speakers of two languages, Dutch and Estonian, who completed two different personality questionnaires, the NEO-PI-3 and HEXACO-PI-R. An outstanding agreement was achieved in the most occasions: in only 4-6% of dyadic pairs was the correlation...
The aim of this paper is three-fold. First, we identified self- and informant-rated Five-Factor Model (FFM) personality domains and facets associated with diabetes diagnosis. Second, we tested whether the associations were independent of the rater method-specific variance. Lastly, we examined whether the observed associations were mediated by BMI,...
Remembering the emotions we have experienced in the past is the core of one's unique life-experience. However, there are many factors, both at the state and trait level that can affect the way past feelings are seen. The main aim of the current study was to examine the impact of individual differences on systematic biases in retrospective ratings c...
and Keywords Personality psychologists—perhaps even more than in some other disciplines—are deeply interested in what is common to personality descriptions in all cultures and societies. The purpose of this chapter is to discuss the potential universality of the Five-Factor Model (FFM) of general personality structure. The chapter begins with a dis...
Intraindividual variability, along with the more frequently studied between-person variability, has been argued to be one of the basic building blocks of emotional experience. The aim of the current study is to examine whether intraindividual variability in affect predicts tiredness in daily life. Intraindividual variability in affect was studied w...
The current study examined the relationship between the Five-Factor Model personality traits and physician-confirmed peptic ulcer disease (PUD) diagnosis in a large population-based adult sample, controlling for the relevant behavioral and sociodemographic factors. Personality traits were assessed by participants themselves and by knowledgeable inf...
Extraversion is a relatively stable and heritable personality trait associated with numerous psychosocial, lifestyle and health outcomes. Despite its substantial heritability, no genetic variants have been detected in previous genome-wide association (GWA) studies, which may be due to relatively small sample sizes of those studies. Here, we report...
In personality research, trait–outcome associations are often studied by correlating scale sum scores with an outcome. For example, an association between the NEO Impulsiveness scale and body mass index (BMI) is often interpreted to pertain to underlying trait Impulsiveness. We propose that this expectation can be corroborated by testing for Spearm...
It is argued that if we compute self-other agreement on some personality traits then we possess no or very little information about the individuals who are the targets of this judgment. This idea is largely based on two separate ways of computing self-other agreement: trait agreement (rT) and profile agreement (rP), which are typically associated w...
