The development and evaluation of systems for describing and classifying tasks which can improve generalization of research results about human performance is essential for organizing, communicating, and implementing these research findings. The present report describes research undertaken to develop one such system--a task characteristics approach. Basic objectives were to develop descriptive characteristics of tasks assess the reliability of rating scales devised to measure these characteristics and determine if these characteristics represented correlates of performance. Major components of a task were identified and treated as categories within which to devise task characteristics or descriptors. Multiple correlations were obtained between task characteristic ratings and the performance measures.
