The association between body image and smoking cessation among individuals living with HIV/AIDS

Lower smoking cessation rates are associated with body image concerns in the general population. This relationship is particularly important to study in individuals living with HIV/AIDS due to alarmingly high smoking rates and considerable bodily changes experienced with HIV disease progression and treatment. The association between body image and smoking cessation rates was examined among individuals living with HIV/AIDS participating in a smoking cessation intervention. Body image concerns were significantly associated with depression, anxiety, stress, and social support, all variables known to affect cessation rates. However, reduced quit rates were found among individuals reporting elevated and low levels of body image concerns at the end of treatment. These findings suggest a unique relationship between smoking and body image among individuals living with HIV/AIDS. Further research is needed to examine these effects and whether moderate levels of body image concerns in this population reflect realistic body perceptions associated with positive mental health.     

Mind-set matters: exercise and the placebo effect

In a study testing whether the relationship between exercise and health is moderated by one's mind-set, 84 female room attendants working in seven different hotels were measured on physiological health variables affected by exercise. Those in the informed condition were told that the work they do (cleaning hotel rooms) is good exercise and satisfies the Surgeon General's recommendations for an active lifestyle. Examples of how their work was exercise were provided. Subjects in the control group were not given this information. Although actual behavior did not change, 4 weeks after the intervention, the informed group perceived themselves to be getting significantly more exercise than before. As a result, compared with the control group, they showed a decrease in weight, blood pressure, body fat, waist-to-hip ratio, and body mass index. These results support the hypothesis that exercise affects health in part or in whole via the placebo effect.     

Failure of positive but not negative emotional valence to enhance memory in schizophrenia

Abnormalities in the integration of emotion and cognition have long been considered hallmark characteristics of schizophrenia. Study authors used a well-established emotional memory model from the neuroscience literature to assess the facilitative impact of emotional valence of information on long-term memory consolidation in schizophrenia. Participants with schizophrenia (n=33) indicated somewhat higher levels of emotional intensity in response to emotional images than did healthy (n=28) participants. However, when recognition memory was tested 24 hr later, schizophrenia participants did not show enhancement of memory for positive images as was found in healthy participants. Their memory enhancement for negative images did not differ from that of healthy participants. Correlations between self-reported physical and social anhedonia were significantly inversely correlated with intensity ratings of positive stimuli during the encoding phase for healthy participants but were negligible for schizophrenia participants. These results suggest a failure to adequately integrate positive emotional experience in memory consolidation processes in schizophrenia participants, despite appropriate initial response to positive stimuli, which may contribute to symptoms such as anhedonia by reducing the long-term impact of positive experiences in motivating hedonic behavior in day-to-day life.     

In- and outgroup representation in a dynamic society: Hong Kong after 1997

Reunification with the People's Republic of China in 1997 draws attention to the identity of Hong Kong people along with their representation and perception of in- and outgroups. We gathered current data on in- and outgroup representations, self-categorizations, and the willingness to assimilate in this dynamic sociocultural environment. A new experimental method was developed to measure the structure and feature dimensions of in- and outgroup representation in 25 university students and 25 employees. Results showed that the structure of mental representations had changed after reunification. Interestingly, significant feature dimension of intergroup perception, such as modernity and Confucian values, proved to be consistent with earlier research. In the present study, it became obvious that such feature dimensions played an important role in discriminating between in- and outgroups.     

Attitudes and Beliefs About Suicidal Behavior When Coming Out Is the Precipitant of the Suicidal Behavior

Young persons who identify as lesbian, gay, or bisexual (LGB) have higher rates of nonfatal suicidal behavior than their heterosexual peers. It has been suggested that suicidal behavior may be a painful but unavoidable rite of passage for LGB youths at the coming out stage. Could this mean that suicidal behavior is considered understandable and even permissible behavior for LGB youths at this stage? In this study we explored reactions to a suicidal decision when coming out was the precipitant of the suicidal act. Specifically, we compared attitudes toward a suicidal decision after coming out and being rejected by one's parents with attitudes toward a suicidal decision after experiencing other stressors (i.e., a physical illness, a relationship loss, or an academic failure). Contrary to expectation, the decision to engage in suicidal behavior following coming out was not viewed in relatively accepting terms. Rather, it was perceived as unsound and weak. As in previous studies, physical illness was singled out as a relatively understandable motivation for suicidal behavior. In addition, we found that androgynous persons viewed the suicidal decision as more unsound than other gender-identity types, independent of precipitant. Given similar evidence from other studies, future research might explore the role of androgyny in the protection against suicidal behavior.

     

Emotional Responses to Pictures of Oneself in Healthy College Age Females

Emotional responses related to self-perceptions were investigated in healthy college-aged females using a picture-viewing paradigm that consisted of four categories of pictures (pleasant, neutral, unpleasant, and full body pictures of themselves). The startle eye-blink reflex, facial EMG, and self-reported valence, arousal, and dominance measures were recorded for each picture. Startle reflex and facial EMG measures exhibited decreased activation for self-pictures compared to the other affective categories. Self-reports indicated self-pictures were rated as moderately pleasant, low arousing, and moderately dominant relative to the other affective picture categories. The findings of reduced startle blink reflex coupled with decreased activation for all facial EMG measures and the moderate self-report ratings suggest increased attentional processing for self-pictures. These findings provide an understanding of emotional responses to self-perceptions in healthy young females.     

Connotative Interpretations of Sexuality-Related Terms

In this study we examined the connotative interpretations of selected sexuality-related terms by a cohort of university undergraduate students (n=567). Forty-two sexuality-relevant constructs were rated on thirty 7-point semantic differential scales. Means of the scale sum scores for men and women were compared using t tests. Among women the most favorably rated constructs were orgasm, vaginal sex, sexual intercourse, virginity, masturbation, oral sex, pro-choice, pregnancy, erection, and heterosexual. The most negatively evaluated terms were date rape, sexual abuse, rape, sexual assault, HPV, and HIV/AIDS. For men, the most favorably rated constructs were sexual monogamy, virginity, orgasm, vaginal sex, and heterosexual. The most negatively evaluated terms were rape, HPV, date rape, and sexual abuse. There were statistically significant gender differences in the evaluation of 12 terms (p<.05). The evaluations assigned to 30 possible attributes suggest that some sexuality-related terms elicit strong visceral responses from university students. A discussion of the psychological and emotional impact of sexuality-related terms (i.e., connotative meanings) may be warranted whenever dictionary definitions (i.e., denotative meanings) are presented to students, other groups of learners, and persons in health care and other settings. Moreover, a practitioner's use of language may elicit connotatively different responses for women and men.     

Relational and imageric recall in young and older adults under conditions of high task demand

Research indicates the presence of an age-related pictorial processing deficit, for which the elderly may attempt to compensate through the use of relational information. Cognitive asynchrony theory, a recent synthetic formulation which unites elements of the generalized slowing hypothesis, environmental support theory, and the item-specific/relational information distinction, has proven useful in a number of experiments in explaining these aspects of visual cognitive aging. The present experiments tested this theoretical formulation under high processing demand conditions in both the relational and the pictorial/item-specific realm. Young and older adults yielded a complex pattern of results consistent with the cognitive asynchrony synthesis of these theoretical considerations. The present experiments add to the growing body of findings indicating that the cognitive subsystems of memory decline at different rates, that the differences in cognitive processing between young and older adults tend to be more quantitative than qualitative, and that the global age-related memory deficits of popular belief are in fact relatively circumscribed and specific.
