Abstract
Three experiments that examined whether short-term practice would attenuate initial differences among coding conditions are reported. Experiment (Exp.) 1 showed that differences among coding conditions became less pronounced with practice for measures of response-time (RT) and accuracy. This was due primarily to a greater degree of improvement with achromatic shape-coding compared to color-coding. Exps. 2 and 3, which used a more difficult task, showed that for an identification task, practice generally improved RT and reduced differences among coding conditions. For a search task, practice enhanced RT with color-coding conditions, but impaired RT with shape-coding. This impairment presumably reflected fatigue effects induced by the most difficult coding condition.
