CONSPICUITY CODING OF UPDATED SYMBOLIC INFORMATION,
Abstract
The study is concerned with (1) the degree to which extraction and assimilation of information is affected by the amount of information presented in a slide and by the type and extent of change introduced in updating, and (2) the extent to which performance can be improved through various enhancement techniques such as coding updated for conspicuity or providing hard copy history-showing the situation before updating--for comparison with updated slides. If the extent of improvement to be attained by such techniques is known, the value of such improvement can be balanced against the cost of providing such aids. Specific objectives were: (1) To determine the separate and interactive effects on speed and accuracy of information extraction and assimilation of (a) three different amounts of information presented, (b) three types of updating change, and (c) three extents of updating change. (2) To determine the extent to which performance under the experimental conditions imposed can be enhanced by either of two methods of coding updates and by provision of hard copy.
