The five papers presented in this volume discuss the relationship between the psychomotor domain and instructional technology and are intended to serve as resource materials for instructional technologists. The first chapter focuses upon a consideration of the senses of reality and the second upon some general considerations of the psychomotor domain. The third paper offers a classification of educational objectives in this area, and the fourth considers some educational implications of the structure and measurement of psychomotor abilities. The concluding chapter, a joint effort of four authors, examines the impact of four major factors upon psychomotor performance effectiveness. These factors are environmental stressors, time/work fatigue, toxic and drug effects, and task loading. (LB)
