Abstract
A well‐trained panel is a valuable tool for describing and quantifying characteristics of a food product. This research was undertaken to study the effects of feedback during panel training. A computerized system was designed using the Macintosh computer to gather data and provide panelists with individualized instruction and immediate graphic feedback. Two levels of feedback (with or without) were delivered to the panelists over a 2‐week training period. Feedback consisted of correct response for discrimination testing and a graph displaying means and deviations for scaled data. Results showed an expansion in the use of the line scale and an increase in precision across trials. No notable change in magnitude estimation sample scores was observed across feedback conditions; however, deviations were lower following feedback. Although exposure/practice alone provided similar changes, further differences were affected with graphic feedback. Results suggested individualized computer assisted instruction with graphic feedback may provide an efficient and effective tool to complement existing panel training techniques.
