Going beyond the specifics: Generalization of single actions, but not temporal order, at 9 months

We examined generalization in 9-month-old infants after a 24-h delay using deferred imitation. Infants flexibly applied their knowledge of sequence actions across changes in props even though they had no opportunity for immediate imitation.     

Changing “us” and hostility towards “them”—Implicit theories of national identity determine prejudice and participation rates in an anti-immigrant petition

National identity definitions determine who belongs to the national ingroup (e.g., “us Germans”) versus the “foreign” outgroup prone to hostile outgroup bias. We conducted five studies in two countries investigating if viewing the ingroup's national identity as fixed exacerbates the perceived divide between ingroup and outgroup and thus increases anti-immigrant hostility, while a malleable view blurs the divide and reduces anti-immigrant hostility. In a Prestudy (58 participants), an Implicit Theory of National Identity Scale was developed. In Studies 1 (154 participants) and 2 (390 participants), our scale predicted individuals’ prejudice and participation rates in a hypothetical referendum and a real petition against immigrants. In Studies 3 (225 participants) and 4 (225 participants), experimental evidence was obtained. Leading participants to believe that the definition of “a true compatriot” changes over time (rather than remaining the same) resulted in lower levels of prejudice and participation rates in an anti-immigrant petition.     

The Role of Maternal Verbal, Affective, and Behavioral Support in Preschool Children's Independent and Collaborative Autobiographical Memory Reports

The authors investigated the individual and relative contributions of different aspects of maternal support (i.e., verbal, affective, and behavioral) in relation to children's collaborative and independent reminiscing. Four-year-old children discussed personal past experiences with their mothers and with a researcher. In collaborative recall with their mothers, children's narrative behavior was regulated best by maternal use of specific elaborative components, such as affirmations. In contrast, in children's independent recall, affective and behavioral qualities of maternal support were related to children's memory performance. Specifically, during free-recall, the dimensions of quality of instruction and respect for autonomy were significant predictors of children's narratives. In the context of prompted recall (supported by wh-questions), respect for autonomy was the only significant predictor of children's involvement in the conversations and of the amount of unique content they provided. The findings suggest that different aspects of maternal behavior facilitate different components of children's reminiscing skills, which children might apply depending on demands of the autobiographical memory conversation.     

The memory is in the details: Relations between memory for the specific features of events and long-term recall during infancy

The second year of life is marked by pronounced changes in the length of time over which events are remembered. We tested whether the age-related differences are related to differences in memory for the specific features of events. In our study, 16- and 20-month-olds were tested for immediate and long-term recall of individual actions and temporal order of actions of three-step sequences in an elicited imitation paradigm as well as for forced-choice recognition of the specific feature of the props used to produce the sequences. Memory for the props was related to long-term recall of the events only for the 20-month-olds. It accounted for unique variance above and beyond the variance explained by immediate recall of the individual actions and the temporal order of actions of the sequences. The different pattern of relations in the older and younger infants seemingly reflects a developmental difference in the determinants of long-term recall over the second year of life.     

A Field Study of the Role of Big Five Personality in Applicant Perceptions of Selection Fairness,Self, and the Hiring Organization

Although there is a growing applicant reactions literature, relatively little work has addressed the role of personality in applicant perceptions. Using a sample of actual law enforcement applicants (N=120), we studied the relationship between Big Five personality measured before a written test and applicants' post‐test fairness perceptions, perceptions of themselves, and perceptions of the hiring organization. Personality was related to applicant perceptions after controlling for gender and test score. Personality also accounted for significant variance in self‐perceptions and perceptions of the hiring organization beyond that accounted for by fairness perceptions. Neuroticism and agreeableness were the most consistent predictors of applicant perceptions. Our discussion focuses on the consideration of individual differences in applicant reactions research.     

The dawning of a past: the emergence of long-term explicit memory in infancy.

The ability to recall information about the past is thought to emerge in the 2nd half of the 1st year of life. Although there is evidence from both cognitive neuroscience and behavioral psychology to support this hypothesis, there is little longitudinal evidence with which the question can be addressed. Infants' memory abilities were tested between the ages of 9 and 16 months using elicited and deferred imitation. Infants' memory for events was tested after delays ranging from 1 to 6 months. The results suggest that at 9 months of age, infants are able to store and retrieve representations over delays of as many as 4 weeks but not over long delays. In contrast, 10-month-olds have at their disposal a system that allows encoding and retrieval of event representations over delays of up to 6 months. These results support the idea that the system that underlies long-term ordered recall emerges near the end of the 1st year of life.
