Drug use and deviation from self-concept norms

The more the deviation from a sex-and-grade, self-concept score norm (as indexed on a pair-comparisons, adjectival inventory), the greater the incidence of reported drug use. This assertion applies (a) to both sexes (teenagers) for beer and wine, cigarettes, hard liquor, and marijuana, and (b) to males alone for speed and LSD.The first-named author developed the deviancy scale; both authors processed data. In the latter task, they were assisted by Mrs. Edith P. Ferguson, wife of second-named author.     

Independent effects of achievement motivation and overt attribution on achievement behavior

The cognitive attribution theory of achievement motivation was examined in a series of three studies. The persistence of performance under failure feedback was investigated, with improvement over trials on a digit-symbol substitution task constituting the measure of persistence. Although evidence was obtained relating overt causal attributions of failure to persistence, partial correlation statistics indicated that this relationship was independent of achievement motivation. Partial correlation statistics also revealed that the relationship between achievement motivation and persistence was independent of attributional variables. In addition, greater persistence was exhibited by high- than by low-achievement subjects in the absence of attribution differences between these groups. Additional evidence was collected suggesting that the act of overt attribution was an ego-involving operation that led to these achievement differences in improvement. In general, achievement classification and overt causal attributions had separate effects on persistence, precluding the interpretation of achievement-related behavior in terms of attribution theory. Overt causal attributions were found to be, in part, a function of the ego-involving character of the task instructions, as was improvement.Portions of this research were conducted while L. A. White was supported by a Purdue University David Ross Research Fellowship; Kay Deaux, principal investigator.     

Laterality differences and practice effects under central backward masking conditions

Two experiments were conducted to examine laterality differences and practice effects under various central backward masking conditions. Critical stimulus onset asynchrony (SOA) was determined for subjects on 3 consecutive days using single letters as target stimuli (TS) and a pattern masking stimulus (MS). There was a right visual field (RVF) advantage on Day 1 but no difference between the visual fields on following days. The decline in the RVF advantage appeared to be dependent upon prior experience with laterally located letters, to be independent of initial experience with a particular set of letters, and to be more pronounced for females than for males. In addition, large improvements in performance were found, particularly between the first and second testing sessions. These practice effects were discussed in terms of the possible development of strategies for enhancing TS features or attenuating MS features.     

Delayed effects of practiced versus unpracticed responses after observation of movie violence

University men participating in an ostensible study of “impression formation” first received either an insulting or neutral evaluation of themselves from their supposed partner and then watched either a prize fight or an exciting but nonaggressive scene. After this, they either had an opportunity to evaluate their partner right away or they had to wait an hour before evaluating him. On scoring the subjects' written statements about the partner (to be seen by him and the experimenter), it was found that (1) for those given the immediate opportunity to be aggressive, the violent movie increased the strength of the angered subjects' initial attack on their partner over that displayed by the similarly insulted men shown the nonaggressive film; (2) if the angry subjects had to wait an hour before evaluating their partner, there was no difference between the aggressive and nonaggressive movie groups; (3) the aggression-heightening effect of the violent scene did carry over the intervening hour, however, if the insulted men had been given the earlier opportunity to evaluate their partner. It is suggested that the performance of an aggressive response soon after seeing an aggressive film increases the persistence of the aggressive reactions over time.     

Physical attractiveness and its relationship to sex-role stereotyping

On the basis of recent findings showing that physical attractiveness serves as an important evaluative cue in person perception, the present paper reviews evidence which indicates that physical attractiveness differentially affects the judgments of males and females. Recent research seems to indicate that the physical-attractiveness stereotype — which holds that attractive individuals are more positively evaluated across a wide range of dimensions than unattractive individuals — is more potent when applied to women than to men. The origins of this differential stereotyping are discussed in terms of the historically defined roles of men and women in our society. In addition, the paper discusses the implications of the physical-attractiveness stereotype for the general problem of sex-role stereotyping.     

The effects of gormone manipulations on aggressive target-biting in mice

Aggressive biting of an inanimate target by mice was studied. Males attacked the bite-target more frequently than females, but this difference disappeared after castration when the response rate of the males approached that of the females. Ovariectomizing the females had little effect on their bite-attack frequencies. Subsequent androgen injections restored the biting-attack frequency of the castrated males to preoperative levels but had little effect on the intact males. Estrogen had little effect on the response frequency of the females, whereas androgen produced a slight increase in their bite-attack frequency. Results indicate that androgen is critical for the maintenance of this aggressive response and that the single subject paradigm utilized in this study was a sensitive measure of aggressive tendencies in mice.
