Remembering Early Childhood: How Much, How, and Why (or Why Not)

In this article, we consider recent research on three questions about people's memories for their early childhood: whether childhood amnesia is a real phenomenon, whether implicit memories survive when explicit memories do not, and why early episodic memories are sketchy. The research leads us to form three conclusions. First, we argue that childhood amnesia is a real phenomenon, as long as the term is defined clearly. Specifically, people are able to recall parts of their lives from the period between ages 2 and 5 years, but they recall less from that period than from other periods. Second, we conclude that implicit memories from early childhood may be evident even when explicit memories are not, a finding that suggests early experience may affect behavior in ways that people do not consciously recognize. Third, we argue that although young children are well known to be wonderfully efficient learners of semantic information, they have difficulty in either encoding or retrieving the interlinked aspects of events that lend them their autobiographical character. Although more evidence is needed, the relative lack of episodic memories of early childhood may be linked to maturation of prefrontal cortex.     

Promoting the Transition from Implicit to Explicit Understanding: A Training Study of False Belief

Ninety‐one children aged between 2;10 and 5;0 participated in a training study of false belief. Children were assigned to either an explanation condition, a practice condition or a control condition where children heard two stories unrelated to false belief. Children’s eye movements in anticipation of the protagonist reappearing were monitored at pre‐test. Only the explanation condition led to improvements in judgement and justification of a protagonist’s future action based on false belief. Children who looked in anticipation to where the protagonist thought the object was at pre‐test were more likely to give a correct judgement at post‐test than those who did not. Those children in the explanation group who gave a correct judgement at pre‐test were more likely to give an appropriate justification at post‐test than those who did not. Three main conclusions are drawn: (1) providing explanation about the underlying principles of a task is more likely to lead to improvements in performance than merely informing children of whether their response is correct; (2) the nature of improvements in performance will depend on the level of knowledge of the child at pre‐test; (3) training will only be beneficial for those children who demonstrate evidence of implicit understanding.     

Does Social Drinking Affect Memory in Older Adults?

The present study examines the possible impact of drinking status on objective memory performance in older adults. Subjects were 214 seniors who were participating in a memory research project and had been screened for cognitive impairment. Cognitive measures included the California Verbal Learning Test (CVLT) and the visual reproduction subtest of the Wechsler Memory Scale–Revised. Drinking status classification (i.e., abstinent, past drinker, light drinker, moderate drinker, and problem drinker) was based on the Alcohol Use Disorder Identification Test scores for the past year and report of past drinking history. Very few subjects were classified in the problem group, with the majority abstaining in the past year. Findings indicated that problem drinkers differed from moderate social drinkers on immediate visual memory, and also had a trend for more retroactive interference on the CVLT. There was no evidence that moderate social drinking (average 13.6 standard drinks) had an adverse impact on memory in this population.     

Home literacy activities and their influence on early literacy skills.

The relationship between the home environments of 66 children and their language and literacy development was examined. After accounting for child age, parent education, and child ability as indexed by scores on a rapid automatized naming task and Block Design of the WPPSI-R, shared book reading at home made no contribution to the prediction of the literacy skills of letter name and letter sound knowledge in kindergarten. In contrast, home activities involving letters predicted modest and statistically significant amounts of variance. For the areas of receptive vocabulary and phonological sensitivity, neither shared book reading nor letter activities were predictive. Follow-up to mid-Grade 2 underscored the importance of letter name/sound knowledge and phonological sensitivity in kindergarten in accounting for individual differences in later achievement in reading comprehension, phonological spelling, and conventional spelling.     

ON MOTIVATED ROLE SELECTION: GENDER BELIEFS, DISTANT GOALS, AND CAREER INTEREST

Despite widespread changes in occupational opportunities, men and women continue to show divergent preferences for careers. This research invoked a motivational framework to explain sex-differentiated career interest. From a role congruity perspective ( Diekman & Eagly, 2008 ), the internalization of gender roles leads people to endorse gender-stereotypic goals, which then lead to interest in occupations that afford the pursuit of those goals. Three studies provided evidence for the hypotheses. Study 1 found that male- and female-stereotypic careers were perceived to afford different goals. Studies 2 and 3 found that men and women endorsed different goals and that this gender-normative goal endorsement predicted gender-stereotypic career interest. In addition, structural equation modeling (Study 3) indicated that internalization of gender roles fully accounted for sex-differentiated goal endorsement. These findings thus extend the social role theory framework to consider processes related to self-selection into specific social roles.
