45 university Ss practiced balancing on a stabilometer to a performance criterion (Day 1) and then were designated as fast, medium, and slow learners based on the number of trials needed to attain it. Each S received an additional number of trials the following day (Day 2) equal to the number needed to reach the criterion (100% overlearning). Absolute and relative retention scores were calculated following a retention interval of 1 wk. No significant difference was found between the fast and slow learners on absolute recall, although the results favored the fast learners. The fast learners showed significant reminiscence between Day 1 and Day 2 and following the 1-wk. retention interval. It was concluded that the "equal amount learned" method did not discriminate against the fast learner and that speed of learning may be an important factor in determining whether or not reminiscence occurs following the attainment of a performance criterion.
120 male university students were tested on a Koerth pursuit rotor. One group of 60 Ss was tested on each of 6 days spaced throughout a 3-wk. period. Another group of 60 Ss performed the same task in an identical manner for test-retest days only, with the retest day following by 3 wk. One group had a large amount of practice while the other did not within a comparable time period. Each practice session consisted of 60 15-sec. trials. The effects of both practice and layoff on intertrial correlations separated by increasing remoteness was investigated. The findings indicated, as others have found, that correlations decrease in size as remoteness increases. Adjacent trial correlations were found to increase as practice increased.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
