Friendship and social competence in a sample of preschool children attending Head Start

Relations between friendship (operationalized as reciprocated or nonreciprocated sociometric choices) and social competence were studied for children (mostly African American) attending Head Start. Initial analyses showed that children with reciprocated friends had higher social competence scores than children without reciprocated friends. Correlations suggested that the number of reciprocated friendships was associated with the social competence indicators studied here. Beyond the cost of having no reciprocated friends, having nonreciprocated friendships was not a liability. Cross-time analyses suggested differing patterns of relations for boys and girls. Having versus not having a reciprocated friend was unstable across time, because there was a trend toward participating in reciprocated friendships from 3 to 4 years of age (most older children had at least 1 reciprocated friend). For girls there was a positive relation between the number of reciprocated friendships at Time 1 and at Time 2. No benefit (in terms of social competence) was found for children making the transition from 1 classroom to the next with a friend.     

Relations of familiarity with reasoning strategies in conspiracy beliefs

The prevalence and resilience of conspiracy beliefs suggest that such beliefs may derive in part from general information-processing mechanisms. Two predictions were tested: conspiracy beliefs would increase as familiarity with the conspiracy increased, and conspiracy beliefs would rest in part on the perception of the alleged conspirators' motive. Participants read condensed versions of four real-life conspiracy theories of varying familiarity, rated their belief in the conspiracies, and explained their ratings. Although belief was not associated with familiarity, participants used different justifications for their beliefs about familiar and unfamiliar conspiracies, relying prominently on motive when the conspiracy was unfamiliar. Preliminary data suggested that participants' beliefs in conspiracies may have been equally strong when they reasoned only in terms of motive as when they reasoned in terms of documented evidence. An additional finding suggested also that beliefs in conspiracies may increase as affiliation with the victim of the alleged conspiracy increases.     

Parental involvement, child temperament, and parents' work hours: Differential relations for mothers and fathers

This study examined how child temperament was related to parents' time spent accessible to and interacting with their 2-year-olds. Bivariate analyses indicated that both fathers and mothers spent more time with temperamentally challenging children than easier children on workdays, but fathers spent less time with challenging children than easier children on non-workdays. After accounting for work hours, some associations between temperament and fathers' workday involvement dropped to non-significance. For fathers, work hours also moderated the relation between irregular temperament and workday play. For mothers, work hours moderated the relation between both difficult and irregular temperament and workday interaction. Mothers also spent more time with girls (but not boys) who were temperamentally irregular. Results speak to the influence of child temperament on parenting behavior, and the differential construction of parenting roles as a function of child characteristics and patterns of work.     

The effects of study-task relevance on perceptual repetition priming

Repetition priming is easily elicited in many traditional paradigms, and the possibility that perceptual priming may be other than an automatic consequence of perception has received little consideration. This issue is explored in two experiments. In Experiment 1, participants named the target from a four-item category search study task more quickly than the nontarget study items at a later naming test. Experiment 2 extended this finding to conditions in which stimuli were individually presented at study. In three different study tasks, stimuli relevant to study-task completion elicited priming on a later test, but stimuli presented outside the context of a task did not. In both experiments, recognition was above chance for nonrelevant stimuli, suggesting that participants explicitly remembered stimuli that did not elicit priming. Results suggest that priming is sensitive to study-task demands and may reflect a more adaptive and flexible mechanism for modification of perceptual processing than previously appreciated.
