This paper describes some of the more spectacular range effects reported in the literature. (Author)

The role of variation as a determinant of infant categorical responding was investigated in three studies of infants 7 to 7 1/2 months of age. Sixty-three infants, divided into groups of 21 each, were habituated to color slide poses of either one, two, or six different adult female faces. Their responses to a novel pose of a familiar face and a…

Eight experiments are reported: the first four demonstrate the context effects in short-term-memory (that retrieval from STM improves as the context for learning is made more similar to the context for retrieval), and four more experiments examine the mechanism by which the context effect might operate.

In a permanently changing environment, it is by no means an easy task to distinguish potentially important events from negligible ones. Yet, to survive, every animal has to continuously face that challenge. How does the brain accomplish this feat? Building on previous work in "Drosophila melanogaster" visual learning, we have developed an…

Effect of instructional conditions on the nature of memory errors was studied using a false recognition procedure. (Authors)

The possible interaction between age-relevant facilitative instructions and the occurrence of phonetic and semantic generalization was investigated. (Author)

Examined effect of emotion on recall of self-generated paired associates under conditions of immediate and delayed retention. Results showed that, with immediate retention, recall of associates to emotional stimuli was significantly lower than to neutral stimuli and, with delayed retention, associations to emotional stimuli were better recalled.…

The purpose of this study was to determine the effects of age differences and differences in memory load on concept identification (CI) tasks of varying levels of complexity. Previous studies with young children found increasingly better performance on CI tasks with increasing age. This was in part due to the fact that older subjects categorize…

Two studies examined the impact of temporal synchrony on infants' learning of and memory for sight-sound pairs. Findings indicated that 7-month-olds had no difficulty learning auditory-visual pairs regardless of temporal synchrony, remembering them 10 minutes later and 1 week later. Three-month-olds showed poorer learning in no-synchrony than in…

A dominant theme in cognitive psychology is that prior knowledge in long-term memory has a strong influence on an individual's cognitive processing. Citing numerous memory studies with children, knowledge base effects are presented as part of a broader picture of memory development. Using the sort/recall procedure (asking subjects to group sets of…

Projects that soon a complete mechanistic understanding of simple forms of learning will be available. Describes some of the recent advances in neuroscience and psychology in understanding the changes in neural circuits that occur during certain behavioral situations. Suggests that learning involves the activation of second messenger systems. (TW)

Describes recent research findings in the area of neurobiology and its relationship to learning and memory. The article provides definitions of associative and nonassociative learning, identifies essential memory trace circuits of the mammalian brain, and discusses some neural mechanisms of learning. (TW)
