The results of studies designed to evaluate individual vs group productivity, problem solving, etc., are often inconsistent andor incomparable. Lack of specification and control of task properties is a major factor contributing to this condition. To study the effects of task properties on group performance the authors propose the use of a vigilance or monitoring task. The present report documents the development of such a task. Thirty-six line and 36 random forms were constructed, and two experiments were conducted to provide a basis for selecting a set of 18 forms having the characteristics of many vigilance tasks, i.e., ease of discrimination and identification. A set of random line forms generated as described in the report can be used in vigilance tasks and permits the specification and control workload in the study of individual and group behavior.
