Discusses the keyword method, which divided vocabulary learning into two stages: (1) the subject associates the spoken foreign word with the keyword, and association that is formed quickly because of the acoustic similarity between the words, and, (2) the subject forms a mental image of the keyword "interacting" with the English translation.…

Individual differences in the ordered recall of list of digits are examined experimentally. The resulting evidence argues that neither differences in rehearsal strategies nor differences in the tendency to group and chunk the digits are major determinants of differences in digit span size. Further experiments attempt to pinpoint the source of…

Taking as the point of departure the landmark work, "A Study of Thinking" (Bruner et al. 1956), this research attempts an analysis of the notion of problem-solving strategy, suggests criteria that may be employed to validate the claim that a certain type of behavior is a strategy, and illustrates the use of the criteria.

Reports on three experiments that: (1) extend the findings of Scarborough et al. (1977) that exposure to single words facilitates lexical judgments of single words, and (2) suggest that recency of exposure may contribute to word "frequency" effects in reading and in learning from written material. (Author/AM)

Like many forms of Pavlovian conditioning, eyelid conditioning displays robust extinction. We used a computer simulation of the cerebellum as a tool to consider the widely accepted view that extinction involves new, inhibitory learning rather than unlearning of acquisition. Previously, this simulation suggested basic mechanistic features of…

An experiment designed to test the generality of Paivio's two factor theory of meaning to sentence comprehension was carried out, and two scoring procedures were investigated: a verbatim score in which sentence elements had to be recalled exactly as they appeared in the original, and a substance score in which synonyms were accepted. The subjects…

This essay introduces a series of studies developing a statistical theory of elementary learning processes. An attempt is made to derive relations among commonly used measures of behavior and quantitative expressions describing simple learning phenomena. Laws of the theory state probability relations between momentary changes in behavioral and…

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 lack of standardization in research involving pictorial variables has made it difficult to clarify the functions of pictorial stimuli in learning. This study sought to determine whether selected methods of rendering pictorial illustrations influenced the number and type of descriptive words evoked in a verbal association task. Normally the…

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)

Reviews recent experimental and theoretical analyses of the relationship between level of processing and retention, and reports on two studies which tested predictions about the effects of orienting activities on retention. (AM)

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 booklet is intended to provide a number of experiments and demonstrations in each area of psychology which may be carried out in situations where the instructor wishes to provide class involvement and some understanding of experimental procedure, but does not have access to the apparatus generally used in experimental psychology. The 75…
