Infants exposed to a set of artificially-created face stimuli having distinct mean and modal prototypes showed a pattern of behavior predicted by category abstraction models. Infants appeared to abstract, at the time of learning, a feature-count summary of the category displayed. (Author/RH)

Compared the effects of depression and brain damage on the Wechsler Adult Intelligence Scale Digit Span subscale and the Wechsler Memory Scale-Revised Logical Memory subtest. Performance on both tests was substantially affected by brain damage, but not by depression. Implications regarding neuropsychological assessment and rehabilitation are…

In a study involving eight mildly mentally retarded and ten CA-matched nonretarded Ss, retarded Ss demonstrated slower overall choice mean reaction times than nonretarded Ss. Results also suggested that the processing difference lies in the memory scanning as opposed to the encoding decision/response of the linear model. (Author/CL)

Two experiments investigated the ability of 3-month-olds to acquire generalized expectancies of reward and the role of these expectancies in memory retrieval. In both experiments, infants exhibited positive transfer over invariant and variable stimulus series; however, in the second experiment, violations of either expected order produced a…

Two experiments examined the effects of a change in a reinforcing stimulus's color on memory for an operant response in three- to four-month-old infants. (Author/RH)

The paper describes recent research investigating the relationship between speed with which individuals can execute basic cognitive processes and performance on tests of intelligence and mental ability. Results are discussed in terms of three properties of the working-memory system which limit the amount of information for simultaneous storing and…

This booklet allows parents to participate in the special education process to encounter an unfamiliar language often referred to as ?acronyms.? It may seem like a foreign language, but it is really just a language of initials, which this booklet explains and defines. Often during school meetings, many of these acronyms are used frequently, and it…

The author reports on European research concerned with the isolation of pituitary products associated with learning, memory and behavior and suggests implications for further research. (CP)
