The Role of Context Dependent Memory on Perceptual Motor Learning in a DSP go/nogo Task

El-Sourani, Nadiya (2010) The Role of Context Dependent Memory on Perceptual Motor Learning in a DSP go/nogo Task.

Abstract:The present study was designed to address the role of context on perceptual –motor learning.. Former studies have only concentrated on the influence of context on perceptual motor learning with regard on task difficulty, this is why this study put emphasis on something different. It was intended to see whether Practice plays a mediating role in the development of contextual dependencies. In line with former investigations the following hypothesis were made: 1.Context will have an influence on the performance of perceptual motor learning. 2.Practice will have a positive influence on motor performance 3. With increasing practice the dependency on contextual cues might diminish. 48 students with a mean age of 22 were subject to the study. A 2x3design was used with context and practice as the between-subject variables (independent) and Reaction time and amount of correct responses as within-subject variables (dependent). The experiment was a DSP go/no task. Subjects had to remember 2 fixed sequences à six and subsequently execute them. The experiment was divided into acquisition phase and retention phase. Amount of practice was altered during Acquisition (one versus five practice blocks) whereas context was altered during retention (same context condition, switched context condition and intentional only context condition). Thus subjects were subject to one of 6 test conditions: short-practice same-context; short-practice switched context, short-practice intentional-only context, long-practice same context, long-practice switched context, long-practice intentional only context. It was found that context had an effect on performance but only if context was switched rather than changed completely. Further practice had enhancing effects on performance. However practice did not act as a mediating factor in the development of contextual dependencies as it did not interact with context.
