Computer-mediated communication and interpersonal attraction: an experimental test of two explanatory hypotheses.

The aims of this study were (a) to investigate the influence of computer-mediated communication (CMC) on interpersonal attraction and (b) to examine two underlying processes in the CMC-interpersonal attraction relationship. We identified two variables that may mediate the influence of CMC on interpersonal attraction: self-disclosure and direct questioning. Focusing on these potential mediating variables, we tested two explanatory hypotheses: the CMC-induced direct questioning hypothesis and the CMC-induced self-disclosure hypothesis. Eighty-one cross-sex dyads were randomly assigned to one of three experimental conditions: text-only CMC, visual CMC, and face-to-face communication. We did not find a direct effect of CMC on interpersonal attraction. However, we did find two positive indirect effects of text-only CMC on interpersonal attraction: text-only CMC stimulated both self-disclosure and direct questioning, both of which in turn enhanced interpersonal attraction. Results are discussed in light of uncertainty reduction theory and CMC theories.     

Social roles and social perception: individual differences in attribution and error

In a replication of the social roles experiment by Ross, Amabile, and Steinmetz (1977), 103 male and female 14-year-olds viewed a brief videotape that showed a randomly assigned "questioner" asking general knowledge questions of a "contestant," who answered most of them incorrectly. Subjects subsequently manifested the role-based attribution error of attributing significantly more knowledge and ability to the arbitrarily designated questioner than to the arbitrarily designated contestant, and this effect was stronger among girls than boys. Personality data were available on the subjects for when they were in nursery school and again at age 14 in the form of independent Q-sort ratings. Personality correlates of the role effect were stronger among boys but manifested a basically similar pattern among girls and suggested that those most prone to make this attribution error, far from being disadvantaged in social judgment, tended to be more socially engaged and competent as well as emotionally well adjusted. The role effect was also positively associated with self-esteem. Personality correlates of attributional generosity and the tendency to attribute high ability to stimulus persons were associated with generally positive interpersonal qualities and attitudes. Results were interpreted in terms of usually appropriate heuristic social competencies that, in special circumstances, may sometimes underlie attribution errors. The general usefulness of examining individual differences in research on social cognition was noted.     

A watched pot sometimes boils: a study of duration experience

The ‘watched pot’ phenomenon — the lengthening of duration experience when one is attentively and perhaps impatiently waiting for some event to occur — was studied in three experiments. In them, each observer attended for a duration of 270 sec to a liquid-containing beaker on an electrical burner. Observers who were told that the experiment concerned time perception (prospective paradigm) reproduced the duration as longer than those told that it concerned visual perception (retrospective paradigm). In the prospective paradigm, reproductions were longer if the liquid did not boil than if it did, and an interruption (task-unrelated questioning) shortened reproductions if the liquid did not boil but had no effect if it did. In the retrospective paradigm, if there was boiling or questioning or both, reproductions were longer than if there was neither. Results have implications for hypotheses about duration experience.     

Memory and the experience of duration in retrospect

Two experiments investigated the relationship between long-term memory for events occurring during an interval and the experience of duration of the interval in retrospect. In both, Ss attended to a sequence consisting of a standard, an experimental, and a second standard interval. Then unexpected comparative duration and memory judgments were requested. In Experiment I, either 30 or 60 unrelated words occurred during the 180-see experimental interval. When more words had occurred, judgments of duration of the experimental interval, judgments of number of words presented, and number of words recognized all increased, but free recall of words was unaffected. In Experiment II, 80 categorized words occurred during the 160-see experimental interval, with category instances in either blocked or random order. When words were blocked by category, judgments of duration of the experimental interval, free recall, and recognition all increased, but judgments of number of words were unaffected. Results were discussed in terms of Ornstein’s (1969) “storage size” hypothesis.     

Perceptual consciousness overflows cognitive access

One of the most important issues concerning the foundations of conscious perception centers on the question of whether perceptual consciousness is rich or sparse. The overflow argument uses a form of 'iconic memory' to argue that perceptual consciousness is richer (i.e., has a higher capacity) than cognitive access: when observing a complex scene we are conscious of more than we can report or think about. Recently, the overflow argument has been challenged both empirically and conceptually. This paper reviews the controversy, arguing that proponents of sparse perception are committed to the postulation of (i) a peculiar kind of generic conscious representation that has no independent rationale and (ii) an unmotivated form of unconscious representation that in some cases conflicts with what we know about unconscious representation.
