Self-consciousness,evaluation of physical characteristics,and physical attractiveness

Results from an investigation of the relationship between habitual awareness of oneself as a social object (Public self-consciousness) and speed of processing information about the overt self are reported. Since high public self-consciousness subjects report themselves to be concerned about their physical appearance, they were expected to have more readily retrievable evaluative judgments concerning their physical characteristics. Consistent with this prediction, high compared to low public consciousness subjects required significantly less time to report their evaluations of eleven of their physical features. In a second study, high public self-consciousness was shown to be positively related to judged physical attractiveness in two geographically diverse samples. The quicker evaluations of the high public self-consciousness group were discussed in terms of information processing model recently described by Markus (1977).     

An informational analysis of actors' and observers' belief attributions in a role-playing situation

An actor's belief in a proposition was inferred by both the actor himself and an observer on the basis of information concerning (a) the actor's preparation and delivery of a speech on the proposition to an unseen audience, and (b) the audience's belief in the proposition. The availability of this information to judges was systematically varied. The position advocated by the actor in his speech and the audience's opinion affected both the actor's belief in the test proposition and the belief attributed to the actor by a disinterested observer. However, neither effect depended upon whether or not other belief-relevant information was also available. These results were interpreted as more consistent with a summative model of information integration than with an averaging model. Actors' behavior had similar effects upon both actors' estimates of how the audience would judge their beliefs and observers' actual estimates of these beliefs. However, these effects were both greater than the effect of their behavior on their own estimates of their beliefs. The apparent strength of the audience's belief in the target proposition had a positive influence upon both actors' beliefs in the proposition and observers' estimates of actors' beliefs, but had a negative, or contrast effect upon actors' expectancies for how the audience would judge their beliefs. Results were more consistent with the differential perspective hypothesis of actor-observer differences proposed by Jones and Nisbett than with the hypothesis that actors and observers differentially weight the implications of their past experience in formulating their judgments. Results had additional implications for the assumptions that persons make when using their behaviors as indications of their beliefs.     

The role of logical and nonlogical factors in making inferences about category membership

Three postulates are proposed concerning the manner in which persons infer the validity of propositions that do not necessarily follow logically from the information available. These postulates assume that subjects first attempt to identify the propositions that are most and least likely to follow from the information given. They then use their beliefs in these propositions as anchors, relative to which the validity of other propositions is evaluated on the basis of both logical and nonlogical criteria. Two experiments are reported in which these postulates are used successfully to diagnose the logical and nonlogical factors that underlie inferences based upon both single statements and sets of syllogistically related propositions. The implications of the proposed postulates for existing formulations of social inference and cognitive organization are discussed.     

Differential acquisition of conditioned suppression in rats with increased and decreased luminance levels as CS + s

Using a conditioned suppression procedure, it was demonstrated that suppression of responding was substantially enhanced when the CS signaling the occurrence of shock was an increment in luminance level (bright CS), relative to an equivalent decrement in luminance level serving as a signal for shock (dim CS). The results of a pseudoconditioning control procedure illustrated that the differential effectiveness of the bright and dim CSs was dependent upon explicit CS-US pairings. The bright and dim stimuli were found to produce equivalent rates of conditioning when they were used to signal the availability of reinforcing stimuli in an appetitive discrimination procedure. The interpretation considered to be most consistent with the data is associative in nature; rats may be brought into the experimental setting prepared to associate bright light with danger and contraprepared to associate dim light with danger.     

Social insulation, self-complexity, and social attraction: A theory chain

In a theory chain extending Byrne's theory of social attraction, links are described between breadth of social interaction and complexity of the self-concept as well as between complexity of the self-concept and social attraction. In the first series of studies, it was shown that communication-handicapped adolescents and physically handicapped children, as well as terminally ill patients, indicate lower self-complexity. In a second series of studies, it was found that persons with more complex self-concepts identify more closely with others, perceive themselves as more similar to objectively dissimilar others, and are more popular sociometrically.     

Individualism, Communitarianism and Consensus

There is a contemporary conflict between individualistic andcommunitarian conceptions of rationality. Robert Goodin describes it asa conflict between an enlightenment individualistic conception of a``sovereign artificer'' and ``a socially unencumbered self'' ascontrasted with the communitarian conception of a ``socially embeddedself'' whose identity is formed by his or her community. Should wejustify and explain rationality individualistically or socially? This isa false dilemma when consensus is reached by a model articulated byKeith Lehrer and Carl Wagner. According to this model, the consensusresults from the positive weights individuals give to others and use tocontinually average and, thus, aggregate their allocations. Aggregationconverges toward a consensus in which the social preference and theindividual preferences become identical. The truth of communitarianismis to be found in the aggregate and the truth of individualism in theaggregation. The original conflict dissolves in rational consensus.     

Skull size and intelligence, and King Robert Bruce's IQ

An estimate of someone's IQ is a potentially informative personal datum. This study examines the association between external skull measurements and IQ scores, and uses the resulting regression equation to provide an estimate of the IQ of King Robert I of Scotland (Robert Bruce, 1274–1329). Participants were 48 relatively healthy Caucasian men (age 71–76 years) resident in Scotland. Using magnetic resonance imaging data, intracranial volume estimated from external skull length and width correlated greater than .5 (p < .001) with measured intracranial area, which correlates very highly with brain volume. IQ scores estimated from the National Adult Reading Test (NART) correlated .56 (p < .001) with measured intracranial area, and .49 (p < .01) with estimated intracranial volume based on external skull width and length. The partial correlation coefficient of this latter association was .25 (p = .09) after adjustment for measured intracranial area. Thus, actual intracranial area accounts for about 74% of the variance shared by NART and estimated intracranial volume. A cast of the skull of Robert Bruce was measured and its intracranial volume estimated. A regression equation between IQ and estimated intracranial volume, based on data from the 48 subjects, estimated the IQ of Robert Bruce at about 128 (95% confidence interval 106 to  130), i.e. almost two standard deviations above the mean. NART scores show a ceiling effect, so this estimated IQ might be an underestimate. Robert Bruce's estimated high IQ is congruent with his military, political and other intellectual achievements.
