Geheugenonzekerheid door perseveratie van motorisch gedrag

Abstract

Introduction Perseveration of motor behavior leads to memory uncertainty. Research shows that when a word must be repeated thirty times compared to three times semantic satiation occurs after thirty times repeating. This study has investigated whether the satiation effect found also occurs when performing motor activities. It also examines the influence of motor perseveration on dissociation and memory uncertainty. Method Dutch students (N = 41) performed twenty motor activities, ten times using a long condition (fifteen times repeating the same operation) and ten times using a short condition (thirteen times repeating an operation and two times another operation). After each trial the students decided as quickly as possible if a presented image was related or unrelated to the last performed action. Based on the 'Clinician-Administered Dissociative State Scale’ participants answered questions about dissociation using VAS scales. Results Relatedness to the image appeared to affect the response time, the number of repetitions did not. There was, contrary to expectations, an interaction effect between both factors: people reacted significantly faster in the long condition when the image was related. Only the number of repetitions appears to affect dissociation. Discussion The study design should control for extra fatigue, however, it creates fatigue in the short condition. In future research OCD patients should be used for a higher generalizability of the study.
