Motivating and reinforcing functions of the male sex role: Social analogues of partial reinforcement,delay of reinforcement,and intermittent shock

After listening to a masculine male, female subjects learned an instrumental escape response reinforced by the opportunity to listen to an androgynous male. The results of three experiments revealed a striking correspondence between conventional learning variables and social analogues of acquisition, partial reinforcement, delay of reinforcement, and intermittent shock. Subject responses to a postconversation questionnaire indicated that the comments made by the androgynous male were judged as more appropriate and more honest, and he was rated as more likable, more intelligent, more moral, and more mentally healthy, than his masculine counterpart. Discussion focused on the importance of investigating male sex role action using additional theoretically relevant social analogues of conventional learning variables and other familiar learning paradigms.     

Relationships among affective and cognitive factors in humor

One hundred and twenty-five college students rated a total of 74 jokes, chosen by stratified sampling, on funniness and on 13 other scales suggested by humor theories. Highly similar factor structures were found with two sets of jokes. Ratings of surprise, resolution, and originality correlated strongly with funniness and helped define a factor on which funniness ratings loaded. Scales pertaining to painfulness, anxiety, or importance of joke topic were positively correlated with funniness but defined a factor essentially independent of it. Partial correlations suggested that these scales were related to funniness through their common relationship with incongruity and resolution scales. Ratings of how much a joke made subjects “feel free” correlated much more highly with ratings of incongruity and resolution than with ratings of painfulness, anxiety, or importance of joke topic. Results were interpreted as providing support for an incongruity-resolution theory of humor, and for the interdependency of affective factors with incongruity-resolution mechanisms.     

The social environments of early infancy in Japan and the United States

The social environments of early infancy in Japan and the United States were compared in terms of the context of caregiving and the quality of the month-infant interaction. Mothers of 17 Japanese infants and 17 infants in the United States were interviewed in their homes about the experiences that they provided for their 4-month-old infants, and mother-infant interactions were recorded on videotape. Levels of parents' education were similar in both countries. The context of the infant's development varied substantially with culture. Mothers in the United States provided a greater variety of experiences on the HOME and care of Japanese infants tended to be more exclusively provided by mothers whereas care of infants in the United States was shared by fathers and other caregivers to a greater extent. Examination of behaviour frequencies during mother-infant interaction indicated that mothers in Japan provided their infants with more vocal input and more physical play than mothers in the United States and Japanese mothers were more vocally responsive to their infants' vocalizations.     

Neurophysiological evidence for disturbances of conflict processing in patients with schizophrenia

Deficits in cognition are a hallmark of schizophrenia. In the present study, the authors investigated the effects of schizophrenia on the neural correlates of conflict processing in a single-trial version of the Stroop task by using event-related brain potentials. Relative to matched controls, patients with schizophrenia showed increased Stroop interference in response time, but this effect was eliminated when the effect of response slowing was controlled. In controls, conflict processing was associated with a negative wave peaking between 400 and 500 ms (N450) and conflict sustained potential (SP) peaking between 600 and 800 ms after stimulus onset. In patients with schizophrenia, the amplitude of the N450 was significantly attenuated and the conflict SP was absent. These results provide evidence for the existence of altered neural processes associated with conflict processing that may be associated with dysfunction of the anterior cingulate and prefrontal cortex in patients with schizophrenia.     

An Evaluation of the Rorschach Method for the Study of Brain Injury

Hospitalized psychiatric patients (n = 115) completed either Form A or Form B of the Whitaker Index of Schizophrenic Thinking, along with the Beck Depression Inventory, State Anxiety Inventory, and the MMPI. Only error scores on the WIST were calculated in an effort to assess validity of the WIST for use in group testing situations where individual timing and administration is cumbersome. Results supported the convergent and discriminant validity of Form A where significant correlations were found with measures of thought disorder (M M PI F, Pt, Sc and Pa) but not with indices of other symptomatology, such as depression and anxiety. Form B did now show such validity, with only one significant correlation with other measures (MMPI Pd). Both WIST Forms correctly identified nonschizophrenics (76% for Form A and 73% for Form B) more often than schizophrenics (57% for each form). Also, Form A was found to be negatively related to years of education. Suggestions for further research on the influence of intelligence and social class variables on WIST scores were made. Overall, Form A emerged as the most valid WIST form, with suggestions for its clinical use being offered.     

Seeing the beauty in everyday people: a qualitative study of young Australians' opinions on body image, the mass media and models

While governments have called for greater body size diversity in media imagery to promote positive body image and prevent disordered eating, the fashion and advertising industries often argue that average-size models do not appeal to consumers. Focus groups were conducted with 76 young Australian women and men to provide a previously neglected consumer perspective on this debate. Thematic analysis identified dissatisfaction with the restricted range of body sizes, and the objectification of women, in media imagery. Participants indicated a desire for change and positive reactions to average-size models in advertising, but also suggested barriers to their increased use, including concerns about the promotion of obesity. The results suggest that there is some consumer support for increased body size diversity in media imagery. Consumer and industry barriers, however, will need to be addressed in the future if this is to be an effective public health intervention to promote positive body image.     

Intimacy, identity and status: Measuring dating goals in late adolescence and emerging adulthood

Individuals?? goals can direct their own social behavior and development. We extended and validated a social dating goals measure (SDGS-R) to assess identity, intimacy and status goals, and compared goals by age, gender, sexual orientation and romantic status. Participants were 121 adolescents and 249 emerging adults (age M?=?20.6). The expected 3-factor structure of the SDGS-R was found and confirmed (18 items). Identity, intimacy and status goals had small correlations with each other and analyses validated the meaning and uniqueness of each goal. Participants reported more identity and intimacy goals than status goals. Intimacy goals were more prominent among older compared to teenage participants and those with a partner rather than without one. Females reported more identity dating goals than males. There was no difference in the goals of same-sex and other-sex attracted youth. The availability of the SDGS-R will allow further study of romantic development and relationship functioning.
