Knowledge of results and signal rate in monitoring: A transfer of training approach

Abstract

This study investigated the transfer effects of training with 3 signal rates and 3 levels of knowledge of results (KR) in a visual monitoring task. Each S monitored for 48 min. under 1 of 9 signal rate-KR conditions on Day 1. On Day 2 all Ss monitored under the medial signal rate with no KR. Results show: (a) on Day 1 mean probability of detection increased with signal rate and amount of KR, (b) these differences persisted on Day 2 when KR was withdrawn, and (c) commissive errors were higher with partial KR than with either full KR or none. It is concluded that training a monitor with KR and high signal rates may improve performance when he must monitor with low signal rates and no feedback. (28 ref.)
