Abstract
AbstractThe link between personality and fertility is relatively underexplored. Moreover, there are only a few studies focusing on the prospective association between personality and childbearing. However, none of these studies considered the Five-Factor Model (FFM), which is the most widely accepted measurement of personality. The present study fills this gap by examining the prospective association between the FFM and the hazard ratio of the first and the second childbirth in Germany. Analyses are based on recent data (2005–2017) from the Socio-economic Panel Study. Cox proportional hazard models are applied. Findings demonstrate that personality traits are associated with fertility. Extraversion is positively linked with the first childbirth, but is negatively associated with the second childbirth. These findings are mainly driven by males. Agreeableness is positively linked with the first childbirth across the total sample. Again, this correlation is mainly based on the findings for men, among whom a positive association between agreeableness and the second childbirth is also found. Among women, personality does not seem to be linked with the first childbirth. However, the risk of having a second child is found to be negatively associated with conscientiousness. My study adds to the current understanding of the personality–fertility association by exploring the impact of personality trait scores from the FFM on subsequent fertility behavior. However, further research is needed on the association between personality and childbearing; on the mechanisms through which personality affects fertility; and on how these links differ across cultures, among higher parities, and for births after re-partnering.

Consistency of noncognitive skills and their relation to educational outcomes in a UK cohort. Transl Psychiatry 2021; 11:563. [PMID: 34741011 PMCID: PMC8571267 DOI: 10.1038/s41398-021-01661-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Revised: 09/22/2021] [Accepted: 10/01/2021] [Indexed: 11/27/2022] Open
Abstract
Noncognitive skills have been shown to associate with a range of health and socioeconomic outcomes. Many studies have relied on cross sectional data and have been unable to assess the longitudinal consistency of noncognitive skill measures. Using data from a UK birth cohort, we investigated a range of noncognitive skills: behavioural problems, social skills, communication, self-esteem, persistence, locus of control, empathy, impulsivity and personality. We assessed their consistency over a 17-year period throughout childhood and adolescence (age 6 months to 18 years), their genomic architecture, and their associations with socioeconomic outcomes. We found high longitudinal measurement consistency for behavioural and communication skills, but low consistency for other noncognitive skills, suggesting a high noise to signal ratio. We observed consistent non-zero heritability estimates and genetic correlations for only behavioural difficulties. Using aggregate measures of each skill over time, we found evidence of phenotypic correlations and heritability ([Formula: see text] = 0.1-0.2) for behaviour, communication, self-esteem and locus of control. Associations between noncognitive skills and educational outcomes were observed for skills measured in mid to late childhood but these were at most a third of the size of IQ-education associations. These results suggest that measures designed to capture noncognitive skills may be subject to considerable response heterogeneity or measurement error. Aggregate measures that leverage repeat responses from longitudinal data may offer researchers more reliable measures that better identify underlying noncognitive skills than cross sectional measures.

Abstract
Openness to experience (OTE) has relatively stable and heritable characteristics. Previous studies have used candidate gene approaches to explore the genetic mechanisms of OTE, but genome-wide polygenic scores have a greater genetic effect than other genetic analysis methods, and previous studies have never examined the potential effect of OTE on this cumulative effect at the level of the brain mechanism. In the present study, we aim to explore the associations between polygenic scores (PGSs) of OTE and brain structure and functions. First, the results of PGSs of OTE at seven different thresholds were calculated in a large Chinese sample (N = 586). Then, we determined the associations between PGSs of OTE and cortical thickness and functional connectivity. The results showed that PGSs of OTE was negatively correlated with the thickness of the fusiform gyrus, and PGSs of OTE were negatively associated with the functional connectivity between the left intraparietal sulcus (IPS) and the right posterior occipital lobe. These findings may suggest that the brain structure of fusiform gyrus and brain functions of IPS and posterior occipital lobe are partly regulated by OTE-related genetic factors.

Abstract
AIMS We investigated the mediating role of leisure activity engagement in the longitudinal relation between openness to experience and subsequent change in executive functioning over 6 years as measured through performance changes in the Trail Making Test (TMT). METHODS We analyzed longitudinal data from 897 older adults (mean = 74.33 years in the first wave) tested on TMT parts A and B in two waves 6 years apart. Participants reported information on leisure activity engagement and openness to experience. RESULTS Latent change score modeling revealed that 37.2% of the longitudinal relation between higher openness to experience in the first wave of data collection and a smaller subsequent increase in TMT completion time from the first to the second wave (i.e., a smaller decline in executive functioning) was mediated via a higher frequency of leisure activities in the first wave. CONCLUSION Individuals with higher openness to experience show greater activity engagement in old age. By enhancing their cognitive reserve, this activity engagement may finally result in smaller subsequent decline in executive functioning.

Abstract
Abstract. In this study, we examine the associations of the scales of the California Psychological Inventory (CPI; a measure of personality traits) with intelligence measured by four cognitive ability tests, completed by a sample of 4,876 working adults. We framed our analyses of the correlations around the investment perspective on the personality-intelligence relationship that proposes traits are associated with investment in intellectual activity, which develops cognitive abilities over time. In particular, we report associations between investment-related scales (Intellectual Efficiency, Flexibility, Achievement via Independence, Psychological-mindedness, and Tolerance) and a higher-order personality factor (Originality) of the CPI with intelligence measured at broad and narrow levels of abstraction. We found positive associations between investment-related scales, and Originality with observed ability test scores and factor g extracted from test scores. We found positive associations of traits with unique variance in verbal ability measures, but negative with measures of quantitative and visuospatial abilities. Our study extends the literature on investment theories of intelligence-personality relations, is the first study to examine the associations of multiple scales of the CPI with intelligence measures, and adds much needed data to the literature from a working adult sample.

Abstract
The investment theory of adult intelligence posits that individual differences in knowledge attainment result from people's differences in cognitive ability and their propensity to apply and invest that ability, which is referred to as investment personality traits. Here, we differentiated intellectual (i.e., intellectual curiosity) and nonintellectual investment (i.e., openness to experience), and we tested their respective predictive validity for knowledge attainment in four independent lab-based studies (overall N = 649). Openness to experience was positively associated with knowledge attainment across all four studies, and this effect was by and large independent of cognitive ability. By contrast, intellectual curiosity was not related to knowledge attainment. The findings suggest that openness to experience, rather than intellectual curiosity, is the investment personality trait that broadly benefits learning and adult intelligence.

Abstract
The complex nature of human cognition has resulted in cognitive genomics lagging behind many other fields in terms of gene discovery using genome-wide association study (GWAS) methods. In an attempt to overcome these barriers, the current study utilized GWAS meta-analysis to examine the association of common genetic variation (~8M single-nucleotide polymorphisms (SNP) with minor allele frequency ⩾1%) to general cognitive function in a sample of 35 298 healthy individuals of European ancestry across 24 cohorts in the Cognitive Genomics Consortium (COGENT). In addition, we utilized individual SNP lookups and polygenic score analyses to identify genetic overlap with other relevant neurobehavioral phenotypes. Our primary GWAS meta-analysis identified two novel SNP loci (top SNPs: rs76114856 in the CENPO gene on chromosome 2 and rs6669072 near LOC105378853 on chromosome 1) associated with cognitive performance at the genome-wide significance level (P<5 × 10-8). Gene-based analysis identified an additional three Bonferroni-corrected significant loci at chromosomes 17q21.31, 17p13.1 and 1p13.3. Altogether, common variation across the genome resulted in a conservatively estimated SNP heritability of 21.5% (s.e.=0.01%) for general cognitive function. Integration with prior GWAS of cognitive performance and educational attainment yielded several additional significant loci. Finally, we found robust polygenic correlations between cognitive performance and educational attainment, several psychiatric disorders, birth length/weight and smoking behavior, as well as a novel genetic association to the personality trait of openness. These data provide new insight into the genetics of neurocognitive function with relevance to understanding the pathophysiology of neuropsychiatric illness.

Abstract
Researchers and the general public have become increasingly intrigued by the roles that systematic tendencies toward thinking, feeling, and behaving might play in academic achievement. Some measures of constructs belonging to this group have been well studied in genetics and psychometrics, while much less is known about measures of other such constructs. The current study focuses on 7 character traits prominently featured in influential intervention-oriented and/or socialization theories of academic achievement: grit, intellectual curiosity, intellectual self-concept, mastery orientation, educational value, intelligence mindset, and test motivation. In a population-based sample of 811 school-aged twins and triplets from the Texas Twin Project, we tested (a) how each measure relates to indices of the Big Five personality traits, (b) how the measures relate to one another, (c) the extent to which each measure is associated with genetic and environmental influences and whether such influences operate through common dimensions of individual differences, and (d) the extent to which genetic and environmental factors mediate the relations between fluid intelligence, character measures, verbal knowledge, and academic achievement. We find moderate relations among the measures that can be captured by a highly heritable common dimension representing a mixture of Openness and Conscientiousness. Moreover, genetically influenced variance in the character measures is associated with multiple measures of verbal knowledge and academic achievement, even after controlling for fluid intelligence. In contrast, environmentally influenced variance in character is largely unrelated to knowledge and achievement outcomes. We propose that character measures popularly used in education may be best conceptualized as indexing facets of personality that are of particular relevance to academic achievement.

What Explains the Heritability of Completed Fertility? Evidence from Two Large Twin Studies. Behav Genet 2016; 47:36-51.

Abstract
In modern societies, individual differences in completed fertility are linked with genotypic differences between individuals. Explaining the heritability of completed fertility has been inconclusive, with alternative explanations centering on family formation timing, pursuit of education, or other psychological traits. We use the twin subsample from the Midlife Development in the United States study and the TwinsUK study to examine these issues. In total, 2606 adult twin pairs reported on their completed fertility, age at first birth and marriage, level of education, Big Five personality traits, and cognitive ability. Quantitative genetic Cholesky models were used to partition the variance in completed fertility into genetic and environmental variance that is shared with other phenotypes and residual variance. Genetic influences on completed fertility are strongly related to family formation timing and less strongly, but significantly, with psychological traits. Multivariate models indicate that family formation, demographic, and psychological phenotypes leave no residual genetic variance in completed fertility in either dataset. Results are largely consistent across U.S. and U.K. sociocultural contexts.

The association of educational attainment, cognitive level of job, and leisure activities during the course of adulthood with cognitive performance in old age: the role of openness to experience.

Abstract
BACKGROUND The relevance of mental health for everyday life functioning and well-being is crucial. In this context, higher educational attainment, higher cognitive level of one's occupation, and more engaging in stimulating leisure activities have been found to be associated with better cognitive functioning in old age. Yet, the detailed pattern of the potential interplay of such a cognitively engaged lifestyle with personality dimensions, such as openness to experience, in their relations to cognitive functioning remains unclear. METHODS Two thousand eight hundred and twelve older adults served as sample for the present study. Psychometric tests on verbal abilities and processing speed were administered. In addition, individuals were retrospectively interviewed on their educational attainment, occupation, and regarding 18 leisure activities that had been carried out in mid-life. Moreover, openness to experience was assessed. RESULTS We found that the effect of openness to experience on cognitive functioning was mediated by educational attainment, cognitive level of job, and engaging in different leisure activities. Data were not better described by alternative moderation models testing for interactive (i.e. dependent) effects of openness to experience and cognitively stimulating engagement. CONCLUSIONS To explain interindividual differences in cognitive functioning in old age, present data are in line with a mechanism in which individuals with high openness to experience may have been more engaged in stimulating activities in early and mid-life. Possibly by increasing their cognitive reserve throughout adulthood, this may finally enhance their cognitive performance level later in old age.

Abstract
Background:
Several studies in the new field of cognitive epidemiology have shown that higher intelligence predicts longer lifespan. This positive correlation might arise from socioeconomic status influencing both intelligence and health; intelligence leading to better health behaviours; and/or some shared genetic factors influencing both intelligence and health. Distinguishing among these hypotheses is crucial for medicine and public health, but can only be accomplished by studying a genetically informative sample.
Methods:
We analysed data from three genetically informative samples containing information on intelligence and mortality: Sample 1, 377 pairs of male veterans from the NAS-NRC US World War II Twin Registry; Sample 2, 246 pairs of twins from the Swedish Twin Registry; and Sample 3, 784 pairs of twins from the Danish Twin Registry. The age at which intelligence was measured differed between the samples. We used three methods of genetic analysis to examine the relationship between intelligence and lifespan: we calculated the proportion of the more intelligent twins who outlived their co-twin; we regressed within-twin-pair lifespan differences on within-twin-pair intelligence differences; and we used the resulting regression coefficients to model the additive genetic covariance. We conducted a meta-analysis of the regression coefficients across the three samples.
Results:
The combined (and all three individual samples) showed a small positive phenotypic correlation between intelligence and lifespan. In the combined sample observed
r
= .12 (95% confidence interval .06 to .18). The additive genetic covariance model supported a genetic relationship between intelligence and lifespan. In the combined sample the genetic contribution to the covariance was 95%; in the US study, 84%; in the Swedish study, 86%, and in the Danish study, 85%.
Conclusions:
The finding of common genetic effects between lifespan and intelligence has important implications for public health, and for those interested in the genetics of intelligence, lifespan or inequalities in health outcomes including lifespan.

Abstract
OBJECTIVES Openness to experience (O) is a well-established personality factor and is associated with cognitive performance. Little is known about the personality-cognitive relationship in bipolar disorder, an illness with significant variability in mood. Cognitive evaluation is essential in psychopathology assessment as it may reflect underlying disease processes and psychosocial functional capacity. Screening using a proxy personality variable may identify those in need of comprehensive cognitive testing. We hypothesized that O and measures of cognition would associate in both the Bipolar Disorder (BD) and healthy control (HC) samples, whereas neuroticism and extraversion would correlate with cognition only in the BD sample. METHODS Data from a longitudinal study of BD were used to study the association between personality factors and cognitive measures of attention, executive functioning, memory and fine motor skills. Regression analyses were used to determine the variables that account for the association between personality and cognition. RESULTS Aspects of O explained significant cognitive variance (~5%) in both groups; this persisted when demographic variables (including BD versus HC status) were considered. Neuroticism and extraversion did not consistently correlate with cognitive performance in either group. LIMITATIONS There were more females in the HC group who were slightly younger compared to the BD group. We lack direct measures of positive affect, and there is a reliance on a single measure of personality. CONCLUSIONS BD Individuals scoring low on self-reported Openness are potential candidates for more comprehensive cognitive assessments (which represent a limited resource).

Abstract
Timing permeates everyday activities such as walking, dancing and music, yet the effect of short-term practice in this ubiquitous activity is largely unknown. In two training experiments involving sessions spread across several days, we examined short-term practice effects on timing variability in a sequential interval production task. In Experiment 1, we varied the mode of response (e.g., drumstick and finger tapping) and the level of sensory feedback. In Experiment 2 we varied the interval in 18 levels ranging from 500 ms to 1624 ms. Both experiments showed a substantial decrease in variability within the first hour of practice, but little thereafter. This effect was similar across mode of response, amount of feedback, and interval duration, and was manifested as a reduction in both local variability (between neighboring intervals) and drift (fluctuation across multiple intervals). The results suggest mainly effects on motor implementation rather than on cognitive timing processes, and have methodological implications for timing studies that have not controlled for practice.

Abstract
Little is known about the relationship between neuropsychological functioning and normal personality in sex offenders. The aim of this study was to examine the relations between personality traits and executive functioning in child molesters. The NEO-Five Factor Inventory was used to assess personality, and the Trail Making Test (parts A and B) was used to assess executive functioning in a sample of child molesters (n = 33). We found the time required to complete Trail Making Test part A significantly predicted Extraversion scores, whereas the time to complete Trail Making Test part B significantly predicted Openness scores. Brief measures of executive functioning can thus predict the score in Extraversion and Openness in child molesters. These personality traits may be related to the functioning of brain areas implicated in having to complete the Trail Making Test.

Abstract
To assess genetic and environmental contributions to personal goals, 1279 twins aged 20-26 filled in Personal Project Analysis and NEO-FFI inventories. Personal goals relating to education, the respondent's own family, friends, property, travel and self showed primarily genetic and unique environmental effects, whereas goals related to parents and relatives showed both shared and unique environmental effects. The variation in goals related to health, work, hobbies and life philosophy was attributable to non-shared environmental effects. Openness to experience and personal goals related to family, education and property shared a significant amount of genetic influence. The same was true for extraversion and self-related goals, and agreeableness and goals related to property.

Abstract
This study investigated the phenotypic, genetic, and environmental relationships between Big Five personality traits and temperamental traits on the basis of the regulative theory of temperament (RTT) using a multitrait-multimethod twin dataset. This allowed us to test specific hypotheses of the five factor theory (FFT) and the RTT. The Big Five personality factors were measured with the Neuroticism-Extraversion-Openness Five-Factor Inventory (NEO-FFI). The six regulatory temperamental traits were captured by the Formal Characteristics of Behavior-Temperament Inventory (FCB-TI). We analyzed self-reports as well as averaged peer ratings from 737 monozygotic and 395 dizygotic twins. Results showed phenotypic links between Big Five and RTT traits that could be attributed mainly to genetic factors. Genetic influences on the variance in Big Five personality traits did not account for the vast majority of genetic variance in all temperamental traits of the RTT contradicting the hypothesis of the FFT that the Big Five exhaustively cover basic temperamental traits. In line with the RTT, the FCB-TI scales showed large genetic links to Neuroticism and Extraversion and rather small links to Openness, Agreeableness, and Conscientiousness, supporting the idea of a differentiation between regulative and integrative aspects of personality.

Abstract
We examined associations between Five Factor Model personality traits and various outcomes of reproductive behavior in a sample of 15 729 women and men from the Wisconsin Longitudinal Study (WLS) and Midlife Development in the United States (MIDUS) survey. Personality and reproductive history was self–reported in adulthood (mean age: 53 years). High extraversion, high openness to experience, and low neuroticism were associated with larger number of children in both sexes, while high agreeableness and low conscientiousness correlated with larger offspring number in women only. These associations were independent of marital status. There were also more specific associations between personality and timing of childbearing. The findings demonstrate that personality traits of the Five Factor Model are systematically associated with multiple reproductive outcomes. Copyright © 2011 John Wiley & Sons, Ltd.

Abstract
Over the past century, academic performance has become the gatekeeper to institutions of higher education, shaping career paths and individual life trajectories. Accordingly, much psychological research has focused on identifying predictors of academic performance, with intelligence and effort emerging as core determinants. In this article, we propose expanding on the traditional set of predictors by adding a third agency: intellectual curiosity. A series of path models based on a meta-analytically derived correlation matrix showed that (a) intelligence is the single most powerful predictor of academic performance; (b) the effects of intelligence on academic performance are not mediated by personality traits; (c) intelligence, Conscientiousness (as marker of effort), and Typical Intellectual Engagement (as marker of intellectual curiosity) are direct, correlated predictors of academic performance; and (d) the additive predictive effect of the personality traits of intellectual curiosity and effort rival that the influence of intelligence. Our results highlight that a “hungry mind” is a core determinant of individual differences in academic achievement.
