Burger or yogurt? Indulgent consumption in impression management contexts

We conducted three studies to investigate indulgent choice in settings with and without impression management by public–private manipulation with evaluation. Study 1 showed that the participants were less indulgent under public scrutiny due to the employment of impression management. Study 2 focused on the impression management context to test the moderate effect of self‐consciousness in two impression managed contexts. Study 3 focused on context without impression management to test the moderate effects of self‐awareness on choices. We found that depending on differences in primed personality, individuals tended to make choices other than those they favoured privately when anticipating that others might form impressions of them based on the decisions made. The findings of all three studies support our basic prediction that people are less indulgent under impression management and suggest that people tend to manage their impression by eating healthier (less indulgently) in public.     

Aging and the perception of 3-D shape from dynamic patterns of binocular disparity

In two experiments, we investigated the ability of younger and older observers to perceive and discriminate 3-D shape from static and dynamic patterns of binocular disparity. In both experiments, the younger observers' discrimination accuracies were 20% higher than those of the older observers. Despite this quantitative difference, in all other respects the older observers performed similarly to the younger observers. Both age groups were similarly affected by changes in the magnitude of binocular disparity, by reductions in binocular correspondence, and by increases in the speed of stereoscopic motion. In addition, observers in both age groups exhibited an advantage in performance for dynamic stereograms when the patterns of binocular disparity contained significant amounts of correspondence "noise." The process of aging does affect stereopsis, but the effects are quantitative rather than qualitative.     

Perceptions of Children Who Lie: Influence of Lie Motive and Benefit

KILMARTIN (1994) suggested that masculine traits may result from externalizing defense style and that when unconscious and unwanted feminine traits about the self occur, they are dealt with in an external way, radier man being directiy resolved by the individual. However, this dieory has received little empirical support. Lobel and Winch (1986) measured defense style among male college students; they found mat men who scored higher in masculinity tended to score higher on acting out (finding an object to attack) and splitting (separating affect from content). Lobel and Winch concluded mat use of diese defense styles reflects avoidance of emotional expression. In turn, diese findings have been supported by research that has suggested mat men use avoidance coping strategies more man women do (McCall &; Struthers, 1994).

Children's Mechanistic Reasoning

Reasoning about mechanisms is one of the hallmarks of disciplined inquiry in science and engineering, but comparatively little is known about its precursors and development. Children at grades 2 and 5 predicted and explained the motion of simple mechanical systems composed entirely of visible linkages (levers). Students' explanations of device behavior suggested four forms of knowledge: simple recognition of device components, noting of structural relations among components, construction of cause-effect rules derived by observation of regularities in device behavior, and identification of essential system components and interactions among components that accounted for cause–effect rules. Only a few children coordinated multiple essential components to constitute a mechanistic causal scheme. Mechanistic causal schemes, in turn, were associated with successful prediction of the output motion of a system. Device tracing via gesture and talk appeared to support this form of knowledge development, and hence may inform future instructional design.     

Prior experience with negative spectral correlations promotes information integration during auditory category learning

Complex sounds vary along a number of acoustic dimensions. These dimensions may exhibit correlations that are familiar to listeners due to their frequent occurrence in natural sounds—namely, speech. However, the precise mechanisms that enable the integration of these dimensions are not well understood. In this study, we examined the categorization of novel auditory stimuli that differed in the correlations of their acoustic dimensions, using decision bound theory. Decision bound theory assumes that stimuli are categorized on the basis of either a single dimension (rule based) or the combination of more than one dimension (information integration) and provides tools for assessing successful integration across multiple acoustic dimensions. In two experiments, we manipulated the stimulus distributions such that in Experiment 1, optimal categorization could be accomplished by either a rule-based or an information integration strategy, while in Experiment 2, optimal categorization was possible only by using an information integration strategy. In both experiments, the pattern of results demonstrated that unidimensional strategies were strongly preferred. Listeners focused on the acoustic dimension most closely related to pitch, suggesting that pitch-based categorization was given preference over timbre-based categorization. Importantly, in Experiment 2, listeners also relied on a two-dimensional information integration strategy, if there was immediate feedback. Furthermore, this strategy was used more often for distributions defined by a negative spectral correlation between stimulus dimensions, as compared with distributions with a positive correlation. These results suggest that prior experience with such correlations might shape short-term auditory category learning.     

Mental health attitudes among Middle Eastern/North African individuals in the United States

ABSTRACT

Middle Eastern/North African (MENA) individuals may have heightened risk for developing mental health problems due to unique cultural stressors. However, traditional cultural and religious practices and beliefs socialised within the family environment may reduce the likelihood of seeking mental health services. This qualitative study aimed to better understand the intersection of cultural, religious, and mental health attitudes among MENA individuals. Semi-structured telephone interviews were conducted with MENA adults who had received therapy services (N?=?13) and were analysed for emergent themes. Respondents reported lack of understanding of mental illness within their communities, and prominent levels of perceived and self-stigma. Families and religious practices/beliefs played an important role in responding to mental illness. Results suggest that incorporating psychoeducation and community awareness campaigns alongside religious services may help to reduce barriers to receiving mental health treatment.     

The Role of Attachment Styles and Interpersonal Problems in Suicide‐Related Behaviors

The relationships among adult attachment styles, interpersonal problems, and categories of suicide‐related behaviors (i.e., self‐harm, suicide attempts, and their co‐occurrence) were examined in a predominantly psychiatric sample (N = 406). Both anxious and avoidant attachment styles were associated with interpersonal problems. In turn, specific interpersonal problems differentially mediated the relations between attachment style and type of suicide‐related behaviors. These findings suggest the importance of distinguishing between these groups of behaviors in terms of etiological pathways, maintenance processes, and treatment interventions.     

Self-Reported Parenting of Clinic-Referred and Non-referred Mexican American Mothers of Young Children

Behavioral parent training (BPT) interventions for child behavior problems have been based on decades of research that demonstrate links between particular parent behaviors and child externalizing problems. However, the majority of this research has been conducted with European-American (EA) families, and less is known about whether these findings can be generalized to Mexican Americans (MAs). In the current study, we investigated self-reported parenting practices that have been associated with externalizing behavior problems among EA families (harsh parenting, inconsistency, and low parental warmth), to determine if those practices can also differentiate MA mothers whose young children have clinically significant behavior problems from MA mothers whose children do not have behavior problems. Participants were 115 MA families with young children, 58 with a child with clinically significant behavior problems and 57 with a child in the normal range for such problems. Results indicated that MA mothers whose children have behavior problems self-reported significantly less warmth and consistency and more harsh parenting compared to parents whose children’s behavior was in the normal range. These findings indicate that parenting behaviors that are associated with externalizing behavior problems among EA families are associated with the same problems among MA families with young children, suggesting that parent training interventions designed to target these behaviors are also likely to be relevant to MA families with children in this age range. However, findings also indicate that parenting behaviors differ depending on acculturation level, suggesting that BPT programs must respond to variation in normative parenting practices for MA families.
