More Effective Consolidation of Episodic Long‐Term Memory in Children Than Adults—Unrelated to Sleep

Abilities to encode and remember events in their spatiotemporal context (episodic memory) rely on brain regions that mature late during childhood and are supported by sleep. We compared the temporal dynamics of episodic memory formation and the role of sleep in this process between 62 children (8–12 years) and 57 adults (18–37 years). Subjects recalled “what–where–when” memories after a short 1‐hr retention interval or after a long 10.5‐hr interval containing either nocturnal sleep or daytime wakefulness. Although children showed diminished recall of episodes after 1 hr, possibly resulting from inferior encoding, unlike adults, they showed no further decrease in recall after 10.5 hr. In both age groups, episodic memory benefitted from sleep. However, children's more effective offline retention was unrelated to sleep.     

Education the Foundation for Freedom and National Strength

One of the most pressing problems facing the nation today is the need to improve and enlarge our higher education system. Many of our college facilities and faculties are already overburdened, yet the number of students seeking higher education will double in the next decade. This paper points out the steps that must be taken to increase the number of potential teachers and to induce sufficient numbers of them to choose teaching as a career. A greater effort must also be made to see that more of our most able high school graduates have an opportunity to pursue a higher education; at present, one third of the top quarter of our high school graduates do not go on to college. A recent study of Russian education made by the U. S. Office of Education is reported and the relative emphasis which Russia and America are placing on education is discussed. The cost of meeting the increased educational needs in America will be immense by current standards, but the cost of not meeting these needs will be far greater.     

Relating self reports of writing behaviour and online task execution using a temporal model

Current theory about writing states that the quality of (meta)cognitive processing (i.e. planning, text production, revising, et cetera) is, at least partly, determined by the temporal distribution of (meta)cognitive activities across task execution. Put simply, the quality of task execution is determined more by when activities are applied than by how often they are applied. Planning and revising are two extreme writing styles, in which (meta)cognitive activities are temporally differently distributed across the writing process. Planners are writers who generate plans before text production. Revisers use text production as a means to arrive at a content plan. The present study investigates the question whether the online (meta)cognitive processing of secondary school students during writing tasks, as measured by think aloud techniques and keystroke logging, can be predicted by their responses to an offline questionnaire which measures to what degree students considered themselves to be planners and revisers. It was expected that different reported writing styles would entail different temporal distributions of six (meta)cognitive activities: reading the assignment, planning, text production, reading own text, evaluating own text and revising. This hypothesis was partly confirmed. The results show that the online temporal distributions of reading the assignment and planning are different for different degrees of reported writing styles. On the basis of these results, the validity of both the questionnaire and the concept of planner and reviser styles are discussed.     

An observational study of social exclusion under varied conditions: gender and developmental differences

To investigate social exclusion, 146 dyads of close friends (N = 292, ages 10, 12, and 14) were observed as they played a board game with a same-gender confederate actor, trained to be a difficult play partner. Verbalizations and gestures were coded for verbal and nonverbal social exclusion, verbal aggression, and verbal assertion. The results indicated few developmental differences. For verbal responses in the presence of the actor, boys were more socially exclusive and verbally aggressive than were girls. Girls engaged in more nonverbal social exclusion in the presence of the actor than did boys. Girls' socially exclusive behaviors were unrelated to other negative behaviors and more strongly related between friends in the actor's absence.
