An analysis of the experiential and behavioral consequences of self-directed attention is proposed, based on cybernetic or information-processing ideas. The proposed model includes the following assumptions: When attention is directed to environmental stimuli, those stimuli are analyzed and categorized according to the person's preexisting recognitory schemas. Self-directed attention often leads to a similar analysis of ^//-information; experientially, such a state of self-focus comprises an enhanced awareness of one's salient self-aspects. In some cases categorization-either of one's context or of some self-elementelicits a response schema, which constitutes a behavioral standard. If a prior categorization has evoked such a behavioral standard, subsequent self-attention engages an automatic sequence in which behavior is altered to conform more closely with the standard. This matching-to-standard is construed as the occurrence within a psychological system of a test-operate-test-exit unit or a negative feedback loop-a cybernetic construct applicable to many different phenomena both within and outside of psychology. More specifically, self-focus when a standard is salient is seen as the "test" or comparison phase of that feedback loop. If the matching-to-standard process is interrupted by one of several specified classes of events, subsequent behavior depends on an outcome expectancy judgment. A favorable outcome expectancy causes a return to the matching-to-standard attempt; an unfavorable expectancy results in behavioral withdrawal. Research support for the model is discussed, and comparisons are made with self-awareness theory, Bandura's theory of fear-based behavior, helplessness theory, and social comparison theory. Psychological theorizing in this century has been characterized by the occasional emergence of quite general theories of behavior (such as psychoanalytic theory and learning theory), with intervening periods in which no general theory has seemed universally applicable and problem-specific theories instead have predominated. In recent years yet another general approach to understanding behavior has begun to coalesce, an approach usually identified with the terms informationprocessing, cybernetic, or control theory (e.g.,
