Die Veranstaltung beginnt um 15 Uhr im Von-Melle-Park 11, Hörsaal.

Abstract:
Response time (RT) is one of the most important variables in Psychology. In RT research and diagnostics, participants repeatedly perform a task, and the average duration between presentation of the stimulus and execution of the correct response is estimated. If incorrect responses occur, this estimation is difficult because the time between presentation of the stimulus and the execution of the correct response is not known in all task repetitions. The ad hoc solution of this problem is to determine RT solely on the basis of the correct responses, which yields an overly optimistic, and incomplete, picture of performance. In this presentation I investigate imputation methods for incorrect responses based on two canonical response time models for two-choice decisions. Using simulations and validation data from a Neuropsychological test battery I investigate reliability and validity of these different performance measures and make recommendations on the treatment of contaminated data in RT research and diagnostics. The improved estimates allow for flexible experimental designs with variable response deadlines.
