Infantile Amnesia: Through a Glass Darkly

Memory for former preschool classmates was examined in 9-and 10-year-old children using measures of both explicit and implicit memory. Yes-no recognition of faces was at low levels but was significantly above chance. Skin conductance data showed similarly low but above-chance differentiation between classmates and controls. A median split of children based on their recognition memory scores showed that children with little evidence of explicit memory for classmates were as likely to show differential skin conductance responding to faces of former classmates as were children with higher recognition scores. Infantile amnesia, like the clinical syndrome for which it is named, may not always involve complete loss of encoded information.     

Trajectories of Infants’ Biobehavioral Development: Timing and Rate of A‐Not‐B Performance Gains and EEG Maturation

This study examined how timing (i.e., relative maturity) and rate (i.e., how quickly infants attain proficiency) of A‐not‐B performance were related to changes in brain activity from age 6 to 12 months. A‐not‐B performance and resting EEG (electroencephalography) were measured monthly from age 6 to 12 months in 28 infants and were modeled using logistic and linear growth curve models. Infants with faster performance rates reached performance milestones earlier. Infants with faster rates of increase in A‐not‐B performance had lower occipital power at 6 months and greater linear increases in occipital power. The results underscore the importance of considering nonlinear change processes for studying infants’ cognitive development as well as how these changes are related to trajectories of EEG power.     

十大独具创意的约会

Go beyond the old standby-dinner and movie-with thesefun date ideas.这些妙趣横生的约会创意打破了以往那种吃完晚餐看电影的俗套,定会给你不同的感觉! The best part about dating-besides the prospect of zeroing in on your "soul mate" -is that you have the perfect excuse to plan interesting outings. True, the din-ner-and -a-movie gambit is a classic, but sitting silently in a theater cuts down on the chance to get to know one     

MICRO‐TEACHING AND STAFF DEVELOPMENT

One of the ways in which closed‐circuit television can contribute to staff development in higher education is through the various techniques associated with and developed from micro‐teaching. In this paper we shall suggest and illustrate ways in which some of the features of micro‐teaching can answer some of the problems of staff development.
