Lay theories and intergroup relations: A social-developmental perspective

Abundant research suggests that the study of lay theories helps to explain intergroup relations. Building on this work as well as “interactionist” theories for understanding social behaviour from developmental and social psychology, we propose an integrative social-developmental perspective examining how lay perceivers' characteristics (e.g., age, race, psychological motivations) interact with the environments in which they are nested to impact lay theory use over time and during life transitions. Using this perspective to guide our investigation of the Protestant work ethic (PWE) and colourblind theory, we show that a single lay theory can have a socially tolerant or intolerant meaning. We review work with US children and adults (Asians, Blacks, Latinos, Whites) as well as research with Colombian children and adults (Mestizos), showing similarities and differences in perceivers' uses of PWE and the colourblind theory. Even when both meanings are prevalent in a given culture, they are not necessarily equally emphasised in all environments or for all people living in those environments, nor are they responded to in the same way by all people. We discuss the implications of these results for theorising on lay theories and offer directions for future work in this area.     

BodiMojo: Effective Internet-based promotion of positive body image in adolescent girls

This study tested the efficacy of an Internet-based health promotion program, BodiMojo, designed to promote positive body image in adolescents. Participants were 178 students (mean age 15.2 years, 67.6% ethnic minority) in three public high schools. Intervention groups used BodiMojo for four weekly health class periods, while controls participated in their usual health curriculum. Body image measures were given at baseline, post-intervention, and 3 months. Girls reported decreased body dissatisfaction (p < .05), decreased physical appearance comparison (p < .05), and increased appearance satisfaction (p < .05), relative to controls. Effects were not maintained at 3-month follow-up. No significant differences were found between the intervention and control groups with boys. Moderation analyses suggested positive effects for diverse adolescents as well as those who were overweight or indicated baseline high body dissatisfaction. BodiMojo appears to be modestly effective in decreasing body image concerns among adolescent girls in the short term.     

No Time to Waste: Restricting Life‐Span Temporal Horizons Decreases the Sunk‐Cost Fallacy

In three studies, we examined the influence of restricted and expansive temporal horizons on the sunk‐cost fallacy. The sunk‐cost fallacy occurs when prior investments instead of future returns influence decisions about future investments. When making decisions about future investments, rational decision makers base decisions on future consequences, not already‐invested costs that are “sunk” and cannot be recovered. In Study 1, we restricted young adult college students' temporal horizons by instructing them to imagine that they did not have much longer to live; this manipulation decreased the sunk‐cost fallacy. In Study 2, we replicated Study 1 and also found that the consequences of manipulating temporal horizons were most pronounced for prior investments of time and that prior investments of time and money had different implications for the sunk‐cost fallacy, depending on the social or nonsocial decision domain. In Study 3, we manipulated temporal horizons by instructing students to imagine their time as a college student was coming to an end. Results were mostly similar to Study 2 but also suggested that focusing on one's mortality may have unique consequences. Implications of the three studies for understanding age differences in sunk‐cost decisions, interventions to improve sunk‐cost decisions, and the situations in which interventions might be most needed are discussed.

Attitudes Towards Potentially Carrying the FMR1 Premutation: Before vs After Testing of Non-Carrier Females with Diminished Ovarian Reserve

Diminished ovarian reserve (DOR) and premature ovarian failure are associated with elevated FMR1 CGG repeat alleles. We assessed pretest attitudes about potentially carrying the FMR1 premutation (FXP) (>55 CGG repeats) among reproductive age women compared with attitudes after learning their non-carrier status. Ninety-two women with DOR, regular menses and no family history of Fragile X Syndrome underwent FMR1 testing and completed attitudinal questionnaires before (T1) and 3 months after learning the test results (T2). The analysis utilized signed rank tests and α?=?0.05. Very few women thought they were likely to have a FXP (6.6 %). More participants thought FMR1 premutations were “serious” at T2 (62.9 %) than at T1 (46.1 %, p?p?相似文献

Multi-Informant Assessments of Adolescent Social Anxiety: Adding Clarity by Leveraging Reports from Unfamiliar Peer Confederates

Adolescent social anxiety (SA) assessments often include adolescent and parent reports, and low reporting correspondence results in uncertainties in clinical decision-making. Adolescents display SA within non-home contexts such as peer interactions. Yet, current methods for collecting peer reports raise confidentiality concerns, though adolescent SA assessments nonetheless would benefit from context-specific reports relevant to adolescent SA (i.e., interactions with unfamiliar peers). In a sample of 89 adolescents (30 Evaluation-Seeking; 59 Community Control), we collected SA reports from adolescents and their parents, and SA reports from unfamiliar peer confederates who interacted with adolescents during 20-minute mock social interactions. Adolescents and parents completed reports on trait measures of adolescent SA and related concerns (e.g., depressive symptoms), and adolescents completed self-reports of state arousal within mock social interactions. Adolescents’ SA reports correlated with reports on parallel measures from parents in the .30s and with peer confederates in the .40s to .50s, whereas reports from parent-confederate dyads correlated in the .07 to .22 range. Adolescent, parent, and peer confederate SA reports related to reports on trait measures of adolescent SA and depressive symptoms, and distinguished Evaluation-Seeking from Community Control Adolescents. Confederates’ SA reports incrementally predicted adolescents’ self-reported SA over and above parent reports, and vice versa, with combined Rs ranging from .51 to .60. These combined Rs approximate typical correspondence levels between informants who observe adolescents in the same context (e.g., mother-father). Adolescent and peer confederate (but not parent) SA reports predicted adolescents’ state arousal in social interactions. These findings have implications for clarifying patterns of reporting correspondence in clinical assessments of adolescent SA.     

Age differences in perceptions of memory strategy effectiveness for recent and remote memory

We examined whether young and older adults hold different beliefs about the effectiveness of memory strategies for specific types of memory tasks and whether memory strategies are perceived to be differentially effective for young, middle-aged, and older targets. Participants rated the effectiveness of five memory strategies for 10 memory tasks at three target ages (20, 50, and 80 years old). Older adults did not strongly differentiate strategy effectiveness, viewing most strategies as similarly effective across memory tasks. Young adults held strategy-specific beliefs, endorsing external aids and physical health as more effective than a positive attitude or internal strategies, without substantial differentiation based on task. We also found differences in anticipated strategy effectiveness for targets of different ages. Older adults described cognitive and physical health strategies as more effective for older than middle-aged targets, whereas young adults expected these strategies to be equally effective for middle-aged and older target adults.
