Zusammenfassung:	This study investigated a visual choice reaction time task to determine its suitability for repeated measures experimentation. Fifteen men served as subjects for one-, two-, and four-choice reaction time conditions. Fifty trials on each condition were administered for 15 days. Results indicated that across all RT conditions, intersession correlations were differentially stable by about Day 8, with reliabilities around .71. Means and variances remained unchanged over the stable days for the RT measure. It was concluded that studies using RT as the dependent variable should allow for at least 1000 practice trials prior to using RT as a performance assessment tool. (Author)
