Intraindividual variability (IIV) in cognitive speed, or moment-to-moment changes in ability, is a developmental phenomenon indicative of neurological integrity that increases gradually across adulthood. Past research has shown that IIV negatively covaries with cognitive performance, in which higher IIV at one occasion is associated with poorer…

Fifth grade students completed ten trials of recalling familiar nouns plus two summary trials. Alpha factor analysis indicated that the measurement procedures may be conceived of as derived from a single domain and the use of a summary trial was a simple way to increase the generalizability of a particular measurement procedure.

A case is made for the construction of nomothetic theories that can also explain individual differences. The discussion uses examples from the memory area and presents an approach to memory that explains individual findings and individual differences in the context of a single model. (SLD)

The purpose of this investigation was to test the efficacy of a study method which was designed to reduce or eliminate verbal learning differences between high and low learning ability Ss. (Authors)

The method of organization in free recall in the form of either clustering or subjective organization is explored in this study. This is just one of the possible forms of retrieval that may be employed. Other possibilities include serial recall, alphabetization, and imagery. To the extent that subjects employ such other strategies, correlations…

Tested the hypothesis that individual differences in immediate-verbal-memory span predict success in second-language vocabulary acquisition. In the two-session study, adult subjects learned 56 English-Finnish translations. Tested one week later, subjects were less likely to remember those words they had difficulty learning, even though they had…
