Prior research has used several indicators to represent parenting, from dyadic interactions between mothers/fathers and children (e.g., parenting styles, parental involvement) to triadic mother-father-child interactions (e.g., coparenting). This study applies network analysis to explore the interrelations between maternal and paternal coparenting,…

When semantically-related photos appear with true-or-false trivia claims, people more often rate the claims as true compared to when photos are absent--"truthiness." This occurs even when the photos lack information useful for assessing veracity. We tested whether truthiness changed in magnitude as a function of participants' age in a…

We tested 6- to 7-year-olds, 18- to 22-year-olds, and 67- to 74-year-olds on an associative memory task that consisted of knowledge-congruent and knowledge-incongruent object-scene pairs that were highly familiar to all age groups. We compared the 3 age groups on their memory congruency effect (i.e., better memory for knowledge-congruent…

Children encounter moral norms in several different social contexts. Often it is in hierarchically structured interactions with parents or other adults, but sometimes it is in more symmetrically structured interactions with peers. Our question was whether children's discussions of moral norms differ in these two contexts. Consequently, we had 4-…

Although children often believe an adult's claims, they may have opportunities to check these claims by gathering relevant empirical evidence themselves. Here, we examine whether children seize such opportunities, especially when the claim is counterintuitive. Chinese preschool and elementary schoolchildren were presented with five different-sized…

The specific strategies that individuals use to regulate their emotions have shown strong associations with various indices of well-being. However, theoretical accounts suggest that strategy use, and the associations between strategy use and well-being, may change across the life span. Attempts have been made to assess whether levels of strategy…

Four studies explored developmental changes in attitudes toward boasting. Overall, 5- to 7-year-olds (N = 130) were more likely than 8- to 11-year-olds (N = 126) and adults (N = 263) to view characters who boasted about valued traits as likable. In Study 1, younger children, unlike the older participants, liked and morally valued boasters who were…

The ability to act jointly with another person is a fundamental requirement for participation in social life. The current study examines the development of action planning in a joint action context. In 4 experiments, 3-, 5-, and 7-year-old children as well as a group of adults (n = 196) interacted with another person to operate a novel apparatus.…

In previous studies, older as compared with younger individuals were more strongly motivated to regulate their momentary affect toward pleasant and calm states. Whether these motivational differences are also reflected in regulatory behavior and whether this behavior is efficient in terms of affect change, however, is unclear. To address these…

Intraindividual variability (IIV) in cognitive speed, or moment-to-moment changes in ability, is a developmental phenomenon indicative of neurological integrity that increases gradually across adulthood. Past research has shown that IIV negatively covaries with cognitive performance, in which higher IIV at one occasion is associated with poorer…

Ageism is recognized as a significant obstacle to older people's well-being, but age discrimination against younger people has attracted less attention. We investigate levels of perceived age discrimination across early to late adulthood, using data from the European Social Survey (ESS), collected in 29 countries (N = 56,272). We test for…

We investigate how the mental lexicon changes over the life span using free association data from over 8,000 individuals, ranging from 10 to 84 years of age, with more than 400 cue words per age group. Using network analysis, with words as nodes and edges defined by the strength of shared associations, we find that associative networks evolve in a…

An ability to perceive tactile and visual stimuli in a common spatial frame of reference is a crucial ingredient in forming a representation of one's own body and the interface between bodily and external space. In this study, the authors investigated young infants' abilities to perceive colocation between tactile and visual stimuli presented on…

Frequent social interactions are strongly linked to positive affect, longevity, and good health. Although there has been extensive research on changes in the size of social networks over time, little attention has been given to the development of contact frequency across the life span. In this cohort-sequential longitudinal study, we examined…

A crossmodal effect has been observed in the processing of facial and vocal emotion in adults and infants. For the first time, we assessed whether this effect is present in childhood by administering a crossmodal task similar to those used in seminal studies featuring emotional faces (i.e., a continuum of emotional expressions running from…
