thesis / dissertation description
Giving employees information about their performance is a common method for employers seeking to improve or change performance. With the popularity of the internet and computers feedback today is often provided through emails, text messages, and video meetings. While feedback has continued to evolve within and across organizations little has been done to assess the impact its delivery through various modalities has. This study explored and evaluated the relationship between the modality which objective feedback is delivered, and the differential effects it produced on performance of a check entering task. This experiment was a laboratory study employing a between-group repeated measures design with random assignment to one of the following four experimental conditions; 1) no feedback, 2) computer delivered feedback, 3) feedback via cell phone text message and, 4) feedback via face-to-face interaction. Inspections of the graphic displays of results reveal unique response patterns, and notable differences in performance across the four conditions. The most prominent difference in performance is seen between the groups receiving objective feedback (through any modality) and the group which received no feedback.
