Five experiments were conducted comparing performance on paired-associate lists of stimuli that rhymed with lists of stimuli that did not rhyme. Results are discussed in terms of the role of input position cues in aiding discrimination among items. (Editor/RK)

It has been suggested that retrieval during a nonreinforced test induces reconsolidation instead of extinction of the mnemonic trace. Reconsolidation would preserve the original memory from the labilization induced by its nonreinforced recall through a hitherto uncharacterized mechanism requiring protein synthesis. Given the importance that such a…

The theoretical and methodological concepts for research on aptitudes as cognitive processes are discussed. Individual differences constructs are reviewed in relation to cognitive processing models, and studies of short-term memory are reviewed. A coordinated approach to the study of aptitude as information processing is recommended. (Author/RD)

The present experiment was designed to vary observation and evaluation independently of each other in an orthogonal design. (Author)

This paper briefly reviews how subjects enhance performance by favoring some stimuli over others. The author calls the mechanism by which this is achieved "expectancy", a generic term including preparatory set, behavioral hypotheses, orienting reflex, and anticipatory goal responses. Temporal and event expectancy are contrasted. Verbal prediction…

Cannabinoid receptors type 1 (CB1) play a central role in both short-term and long-term extinction of auditory-cued fear memory. The molecular mechanisms underlying this function remain to be clarified. Several studies indicated extracellular signal-regulated kinases (ERKs), the phosphatidylinositol 3-kinase with its downstream effector AKT, and…

Reports on research showing that when an event, or a problem, is repeated, the processing of that event is not necessarily repeated. Instead, sometimes the solution is remembered, and this is shown to influence subsequent retention, as well as such tasks as word perception. (AM)

This issue presents the original English version and a French translation of a text written at the Sofia Institute of Suggestology around April 1971. The document defines suggestology and suggestopedia, and traces the development of the suggestopedic method, from the first collective experiments aimed at attaining suggestive hypermnesia carried…

Reports on a study that sought to test theories which predict that spacing between two items to be learned improves the probability of remembering at least one of the items. (AM)

Computational models of infant categorization often fail to elaborate the transitional mechanisms that allow infants to achieve adult performance. In this article, we apply a successful connectionist model of adult category learning to developmental data. The Supervised and Unsupervised Stratified Adaptive Incremental Network (SUSTAIN) model is…

Reviewed in seven author contributed chapters are findings of experimental psychology relevant to the education of handicapped children in the areas of sensory processes, visual perception, memory, cognition and language development, sustained attention and impulse control, and personality and social development. Noted in an introductory chapter…

This volume contains 19 scholarly essays on current research in representative areas of the field of psychology. Topics of the essays include the following: relations between psychology and other sciences, origins of psychology as a science, human memory, cross-cultural cognitive psychology, biology of motivation, organizational behavior, social…
