hen an individual enters the presence of oth ers, they commonly seek to acquire information about him or to bring into play information about him already possessed. They will be interested in his general socio-economic status, his concep tion of self, his attitude toward them, his compe tence, his trustworthiness, etc. Although some of this information seems to be sought almost as an end in itself, there are usually quite practical reasons for acquiring it. Information about the individual helps to define the situation, enabling others to know in advance what he will expect of them and what they may expect of him. Informed in these ways, the others will know how best to act in order to call forth a desired response from him. For those present, many sources of information become accessible and many carriers (or “signvehicles”) become available for conveying this information. If unacquainted with the individual, observers can glean clues from his conduct and appearance which allow them to apply their previ ous experience with individuals roughly similar to the one before them or, more important, to apply untested stereotypes to him. They can also assume from past experience that only individuals of a par ticular kind are likely to be found in a given social setting. They can rely on what the individual says about himself or on documentary evidence he provides as to who and what he is. If they know, or know of, the individual by virtue of experience prior to the interaction, they can rely on assumptions as to the persistence and generality of psychological traits as a means of predicting his present and future behavior. However, during the period in which the indi vidual is in the immediate presence of the others, few events may occur which directly provide the others with the conclusive information they will need if they are to direct wisely their own activity . Many crucial facts lie beyond the time and place of interaction or lie concealed within it. For example, the “true” or “real” attitudes, beliefs, and emotions of the individual can be ascertained only indirectly , through his avowals or through what appears to be involuntary expressive behavior. Similarly , if the individual offers the others a product or service, they will often find that during the interaction there will be no time and place immediately available for eating the pudding that the proof can be found in. They will be forced to accept some events as con ventional or natural signs of something not directly available to the senses. In Ichheiser ’s terms, 1 the individual will have to act so that he intentionally or unintentionally expresses himself, and the others will in turn have to be impressed in some way by him.…
