Each group practiced different tasks, each requiring a response when more than one alternative was available.

The fourth group acted as a comparison group and did not practice a reaction-time task; although they did perform a task on the computer and their reaction times were measured. Before and …

Accuracy Of Performance Measurement: An Investigation Of Training Method And Amount Of Practice, Salvatore J. Cesare
Psychology Theses & Dissertations
The purpose of this research was to investigate the effects of training method and amount of practice-and-feedback on the accuracy of performance ratings and behavioral observation. This research was a 3 x 3 factorial ANOVA design. Training method was comprised of frame-of-reference, cognitive modeling, and a no-training control group. Practice-and-feedback consisted of 0, 1, and 3 practice trials. Undergraduates (N = 99) were randomly assigned to one of nine experimental conditions. Each participant viewed and rated 7 videotaped interview simulations. The results for performance ratings indicated that (a) frame-of-reference training produced the most accurate ratings for elevation, differential elevation, and …
