Social support,self-esteem and depression: Relationship with risk for sexually transmitted infections/HIV transmission

Sexually transmitted infections (STIs) and HIV are important health problems that affect adolescents. The aim of the present study was to analyze the relationship between 1) depression, self-esteem and perceived social support and 2) sexual risk behaviors according to gender. The sample used in this ex post facto study was composed of 1,005 adolescents of both sexes aged between 14 and 18 years. Participants completed several questionnaires in the classrooms of their secondary education schools. The questionnaires assessed depression, self-esteem and perceived social support and recorded information on sexual behavior and socio-demographic issues. Results showed that, among males, self-esteem predicted higher vaginal risk, depression was related to higher vaginal, anal and oral sexual risk, and perceived support from the family predicted lower vaginal and anal sexual risk. Among females, self-esteem was found to be associated with lower anal sexual risk and perceived support from friends predicted lower anal and oral sexual risk. The study highlights the importance of considering family and friends as well as gender differences in the prevention of STIs/HIV.     

Psychological and socio-demographic variables associated with sexual risk behavior for sexually transmitted infections/HIV

New diagnoses of sexually transmitted infections (STIs) and HIV are rising in the adult population. The main objective of this study was to analyze whether knowledge of STIs/HIV, worry about STIs/HIV and pregnancy, and self-efficacy to refuse sex are predictors of sexual risk behaviors among Spanish young and adults. The study sample was composed of 1,106 young and adults of both sexes aged between 17 and 55 years. Results showed that being single, homosexual, having been tested for HIV, having previously contracted an STI, having a college education and earning a monthly income of €900 or more were the characteristics associated with higher scores in knowledge of STIs/HIV. Self-efficacy to refuse sex predicted most vaginal and anal sexual behaviors (i.e., age at vaginal and anal sex initiation and the number of couples that have remained vaginal sex). We also found that participants with greater knowledge of STIs/HIV reported older age at vaginal sex initiation and higher condom use in the first vaginal sexual contact. We consider that these findings can be useful for the development of STI/HIV prevention programs.     

Metacognition, risk behavior, and risk outcomes: the role of perceived intelligence and perceived knowledge.

The present study explores 2 key variables in social metacognition: perceived intelligence and perceived levels of knowledge about a specific content domain. The former represents a judgment of one's knowledge at an abstract level, whereas the latter represents a judgment of one's knowledge in a specific content domain. Data from interviews of approximately 8,411 female adolescents from a national sample were analyzed in a 2-wave panel design with a year between assessments. Higher levels of perceived intelligence at Wave 1 were associated with a lower probability of the occurrence of a pregnancy over the ensuing year independent of actual IQ, self-esteem, and academic aspirations. Higher levels of perceived knowledge about the accurate use of birth control were associated with a higher probability of the occurrence of a pregnancy independent of actual knowledge about accurate use, perceived intelligence, self-esteem, and academic aspirations.     

Potential moral stigma and reactions to sexually transmitted diseases: evidence for a disjunction fallacy

Five experiments demonstrate how potential moral stigma leads people to underplay their susceptibility to sexually transmitted diseases (STDs) and dampens their interest in getting tested. After adding unprotected sex to a list of otherwise innocuous possible vectors for a disease, the authors found that infected people were perceived to be less moral (Experiment 1a), and individuals believed that if they had the disease, others would see them as less moral too (Experiment 1b). Adding this stigmatized vector also reduced reported testing intentions (Experiment 2) and perceived risk of exposure (Experiment 3)--a disjunction fallacy because adding a potential cause reduced estimated likelihood, in violation of basic probability rules. Finally, the authors replicated the effect in a computer virus analog (Experiment 4) and showed that it did not result from simply knowing that one has not engaged in the stigmatized behavior. Results suggest that avoidance of potential stigma can have dramatic health consequences, both for an individual's health decision and for health policy.     

Impact of a social influence intervention on condom use and sexually transmitted infections among establishment-based female sex workers in the Philippines: a multilevel analysis.

The authors assessed the relative impact of structural and social influence interventions on reducing sexually transmitted infections (STIs) and HIV risk behavior among female sex workers in the Philippines (N = 897). Four conditions included manager influence, peer influence, combined manager-peer influence, and control. Intervention effects were assessed at the establishment level in multilevel models because of statistical dependencies among women employed within the same establishments. Control group membership predicted greater perceived risk, less condom use, less HIV/AIDS knowledge, and more negative condom attitudes. Combination participants reported more positive condom attitudes, more establishment policies favoring condom use, and fewer STIs. Manager-only participants reported fewer STIs, lower condom attitudes, less knowledge, and higher perceived risk than peer-only participants. Because interventions were implemented at the city level, baseline and follow-up city differences were analyzed to rule out intervention effects due to preexisting differences.     

Ageism and death: effects of mortality salience and perceived similarity to elders on reactions to elderly people

The present research investigated the hypotheses that elderly people can be reminders of our mortality and that concerns about our own mortality can therefore instigate ageism. In Study 1, college-age participants who saw photos of two elderly people subsequently showed more death accessibility than participants who saw photos of only younger people. In Study 2, making mortality salient for participants increased distancing from the average elderly person and decreased perceptions that the average elderly person possesses favorable attitudes. Mortality salience did not affect ratings of teenagers. In Study 3, these mortality salience effects were moderated by prior reported similarity to elderly people. Distancing from, and derogation of, elderly people after mortality salience occurred only in participants who, weeks before the study, rated their personalities as relatively similar to the average elderly person's. Discussion addresses distinguishing ageism from other forms of prejudice, as well as possibilities for reducing ageism.     

Mood effects on eyewitness memory: Affective influences on susceptibility to misinformation

Does mood influence the accuracy of eyewitness recollections, and people’s susceptibility to misleading information in particular? Based on recent affect-cognition theories and research on eyewitness memory, three experiments predicted and found that positive affect promoted, and negative affect inhibited the incorporation of misleading information into eyewitness memories. This effect was obtained for both positive and negative events (Experiment 1), and for recorded as well as real-life incidents (Experiment 2). Participants had no meta-cognitive awareness of these mood effects, and affect-control instructions were ineffective in preventing them (Experiment 3). The cognitive mechanisms responsible for mood effects on eyewitness memories are discussed, and the implications of these findings for everyday memories, forensic practice and for current affect/cognition theorizing are considered.     

The effects of adaptation to gratings on the perceived orientation of single lines

Subjects were adapted for 45 s to a 5 cycle per degree grating, tilted 10° from the vertical, and at one of four levels of luminance contrast. Estimates of the slope of the grating, or of a single line which replaced the grating, were obtained before and after the period of adaptation by the subject's setting of a single reference line which was located 3° from the edge of the grating. In Experiment I the fixation area was at the centre of the grating, so that half of the grating fell on each retinal hemifield. The reference line was set to a tilt further from the vertical following the period of adaptation, indicating either a change in the apparent orientation of the grating or the reference line. In Experiment II, where the fixation area was midway between the grating and the reference line, so that line and grating appeared in different hemifields, settings indicated no change in the tilt of the grating. In Experiment III, where the fixation area was again midway between grating and setting line, but where the grating was replaced by a single line after the adaptation period, settings indicated that the line had decreased in apparent tilt. The results of the three experiments indicate that while gratings either do not normalize or do so to an insignificant extent they produce a substantial amount of normalization on a single line. Comparison of the results of Experiments I and II shows that spread of this effect outside the directly adapted area is less across the naso-temporal division of the retina than within the same hemifield.     

Coming to grips with weight perception: effects of grasp configuration on perceived heaviness

We investigated how changes in grasp configuration affect perceived heaviness in a weight discrimination task in which participants compared the weights of a series of test objects with the weight of a reference object. In different experiments, we varied the width of the grasp, the number of digits employed, the angle of the grasp surface, and the size of the contact area between the digits and the object. We show that objects are perceived to be lighter when lifting with (1) a wide grip in comparison with a narrow grip, (2) five digits in comparison with two digits, and (3) a large contact area in comparison with a small contact area. However, the angle of the contact surfaces did not influence perceived weight. We suggest that changes in central motor commands associated with grasp differences may influence perceived weight, at least under some conditions.     

Contextual connections within puns: effects on perceived humor and memory

The supposition that perceived humor or cleverness would be enhanced by adding separate content to the alternative meanings of a pun was explored, using Tom Swifties as the research vehicle. Because detecting a punning word relationship might induce arousal, requiring more effort and attentional resources for processing than noting a contextual connection, memory strength for adverbs was also examined using a recognition procedure. Five studies were conducted in which college students were asked to judge 24 Swifties (content counterbalanced across participants) in which presence of pun and context were manipulated. The punning relationship was primarily responsible for perceived humor and cleverness. Presence of a pun also enhanced memory strength (d') as long as the familiarization task focused on humor and cleverness. Coherent context enhanced perceived cleverness inconsistently. It was suggested that a coherent contextual connection may make a greater contribution in more lengthy forms of pun-based word play, such as fables or "shaggy dog" stories.     

Context effects on the perceived physical attractiveness of faces

Four experiments were conducted to study the nature of context effects on the perceived physical attractiveness of faces. In Experiment 1, photos of faces scaled on attractiveness were presented in sets of three, with target faces appearing in the middle flanked by two context faces. The target faces were of average attractiveness, with the context faces being either high, average, or low in attractiveness. The effect of the context was one of assimilation, rather than contrast, regardless of whether the persons in the photos were portrayed to be associated. This result was interpreted in terms of a “generalized halo effect” for judgments of the physical attractiveness of stimuli within a group. Presenting the persons of a set as friends enhanced the perceived attractiveness of the target face but only when the context did not contain a face of low attractiveness. In Experiment 2, the assimilation effect was observed to carry over to influence ratings of the target faces several minutes after the context faces had been removed. Experiment 3 showed the assimilation effect to be robust regardless of whether the context was composed of two faces or one, but Experiment 4 showed the assimilation effect to be evident only when the context faces were presented simultaneously with the target.     

Why it won't happen to me: perceptions of risk factors and susceptibility

Four studies were conducted with college student subjects to examine: (1) perceptions of susceptibility to health and safety risks; (2) factors that subjects see as important in determining their susceptibility; and (3) subjects' actual standing on objective risk factors. Subjects were generally unbiased about hereditary risk factors and were even somewhat pessimistic about environmental risk factors. Their views of their own actions and psychological attributes, however, were excessively optimistic. Few acknowledged actions or psychological attributes that increased their risk. This pattern of findings helps to explain why risks thought to be controllable (i.e., preventable by personal action) are likely to evoke unrealistic optimism about susceptibility. Family histories of health problems were incorporated into judgments of susceptibility, but, except for smoking, correlations between behavioral risk factors and judgments of susceptibility were surprisingly weak. Self-esteem enhancement is suggested as a motive that could explain many of the present findings. Several recommendations are offered for health campaigns that seek to produce more realistic perceptions of susceptibility to health and safety problems.     

Houses built on sand: effects of exemplar stability on susceptibility to attitude change

Attitude representation theory (C. G. Lord & M. R. Lepper, 1999) explains both attitude-behavior consistency and attitude change with the same principles. When individuals respond evaluatively to an attitude object, they activate and combine assumptions about the attitude object with perceptions of the immediate situation. The assumptions activated can vary across time, even without additional information. Previous research has shown that individuals activate exemplars when answering attitude questions, attitude reports vary with the valence of the assumptions activated, and activating differently liked exemplars reduces attitude-behavior consistency. The present research completed study of the theoretical implications of exemplar stability by showing that individuals with temporally unstable exemplars, whether spontaneous (Experiment 1) or manipulated (Experiments 2 and 3), are more susceptible to subsequent attitude change than are individuals with stable exemplars.     

Source expertise and persuasion: the effects of perceived opposition or support on message scrutiny

Compared to nonexperts, expert sources have been considered to elicit more processing of persuasive messages because of expectations that the information is likely to be valid or accurate. However, depending on the position of an advocacy, source expertise could activate other motives that may produce a very different relation from that found in past research. When messages are counterattitudinal (disagreeable), experts should motivate greater processing than nonexpert sources because of expectations that they will likely provide robust opposition to one's existing views. In contrast, when advocacies are proattitudinal (agreeable), nonexpert rather than expert sources should elicit more scrutiny because of perceptions that they will likely provide inadequate support to recipients' current views. Two studies offer evidence consistent with these predictions. Manipulations of source expertise created different expectations regarding the strength of opposition or support, and these perceptions accounted for effects of source expertise on the amount of message scrutiny.
