On the need for longitudinal evidence and multiple measures in behavioral-genetic studies of adult personality

Parental marriage and the non-cognitive abilities of infants and toddlers: Survey findings from China Family Panel Studies

Early childhood is a critical period for developing children's abilities. Non-cognitive abilities are comparable to or even stronger than cognitive abilities in predicting many socioeconomic outcomes. Usually, most scholars take personality as the core indicator of non-cognitive abilities. While temperament is also an important component of children's non-cognitive abilities, it was often ignored in previous studies. Based on the panel data from the 2018 and 2020 China Family Panel Studies (CFPS), this study investigates the effects of parental marital satisfaction on the non-cognitive development of children aged one to three; meanwhile, the heterogeneous effects and mechanisms were also examined. The results show that young children exhibit more negative emotions when their parents reported dissatisfaction with their marriages. Parental depression was an important mechanism of parental marital satisfaction affecting children's non-cognitive development, while the frequency of parent-child interaction was not. The effects of marital dissatisfaction on non-cognitive abilities were heterogeneous across child age and gender, as well as parental genders and education levels. The findings shed some light on the early interventions and offer important reference values for public policies aimed at improving family welfare and children's non-cognitive development.

The Counterpoint of Personality Assessment: Self-Reports and Observer Ratings

In musical counterpoint, two or more different voices sound together in ways that illuminate the possibilities of the musical theme. Similarly, self-reports and observer ratings together may tell us more about personality than either could separately. This article reviews convergence between these two data sources and illustrates ways in which they can be used jointly in personality research to rule out response biases and estimate stability and heritability of personality traits. A measure of profile agreement is introduced and a rule of thumb is proposed for distinguishing agreement from disagreement on specific traits in individual cases. Averaging may be useful when there is agreement about individuals across observers; when there is disagreement, further information should be sought to resolve the competing hypotheses offered by the discrepant ratings.

Recalled parent-child relations and adult personality

Adult children's ratings of their parents' behaviors on the Parent-Child Relation Questionnaire II were correlated with self-reports and peer ratings of personality on the NEO Personality Inventory in a sample of 619 men and women aged 21 to 96. Individuals who reported that their parents were loving scored lower in neuroticism and higher in extraversion, openness to experience, agreeableness, and conscientiousness. Individuals, especially men, who described their parents as casual rather than demanding were lower in extraversion and conscientiousness, but higher in openness. Parental attention (i.e., spoiling) was associated with extraversion and low agreeableness. Several of these correlations were replicated when peer ratings of personality were examined. However, all the associations were modest, and several alternative explanations suggest that the correlations may exaggerate the influence of these child-rearing practices on adult personality. Parental behaviors and attitudes seem to have less effect on broad dimensions of adult personality than traditionally supposed.
