Post-Knowledge of Results Delay: Effects of Interpolated Activity on Learning and Performance

Abstract

The present experiment investigated the effects of interpolated processing activity (IPA) during the post knowledge of results (KR) interval. The study attempted to correct some of the problems inherent in previous research by using a ballistic timing criterion task and assessing the effects of interpolated processing activity (IPA) on both acquisition and No KR transfer trials. To insure that the efficacy of the IPA manipulation, a paced task was used and performance was assessed. Two levels of post-KR delay (5 and 10 s) were factorially combined with two levels of IPA (IPA or No IPA) to yield four experimental groups. Each subject completed 30 KR acquisition trials and 20 No KR transfer trials. Interresponse interval was held constant. In contrast to many previous studies, IPA interfered with the subjects' ability to learn and perform the criterion movement time of 150 ms. Both the memory trace and the perceptual trace were similarly affected. The detrimental effects of IPA on absolute error and objective-subjective error differences found during acquisition persisted during KR withdrawal.     

What Does the Examination for Professional Practice in Psychology Step 2 (EPPP Step 2) Mean for College Counseling: The ASPPB Perspective

We appreciate the opportunity to respond to the Editorial in this issue of the Journal of College Student Psychotherapy by editors Philip Rosenbaum and Ryan Weatherford, who express concerns about the new Examination for Professional Practice in Psychology Step 2 (EPPP Step 2). Our discussion describes the constellation of factors that influenced ASPPB’s decision to develop the EPPP Step 2 at this point in time. We also respond to the concerns expressed about the increasing costs of graduate training and the timing of the EPPP Step 2. Finally this commentary will highlight the difference between the training and licensing processes and will describe how the EPPP Step 2 will help licensing boards fulfill their mandate to protect a vulnerable public.
