判断与决策研究纵观:基于模糊痕迹理论的视角(英文)

模糊痕迹理论是用于解释记忆、判断与决策的综合性理论,该理论的提出和发展主要基于对信息存储、表征、提取和加工过程的研究。本文首先介绍了模糊痕迹理论的基本原则,在此基础上重点讨论了其要义(gist)如何发挥核心作用,使得模糊痕迹理论有别于其他传统的决策模型。该理论将高级直觉与原始冲动性进行了区分,并且预测决策误差来源于判断与决策的各种不同成分,如背景知识、信息表征、提取和加工过程等。模糊痕迹理论不仅可以解释诸如框架效应、合取谬误等传统决策与判断文献中常讨论的误差现象,同时基于该理论的研究还得到了一些与传统决策理论相悖的新发现。此外,对脑与行为如何发育性变化的研究为我们了解成人的认知过程提供了至关重要的新视角,这些对脑与行为的发育性研究和对特殊人群的研究结果也都支持了模糊痕迹理论对要义加工依赖的预测。     

Intersectional experiences of discrimination in a low‐resource urban community: An exploratory latent class analysis

There have been increasing calls for the application of an intersectionality framework to understand and address discrimination and health inequities among diverse communities. Yet there have been theoretical debates regarding to whom intersectionality applies and how intersectional experiences of discrimination are associated with health outcomes. The current study aimed to contribute to these theoretical debates and inform practical applications to reduce health inequities. Data were drawn from a community health survey in New Haven, CT (N = 1,293 adults) and analysed using latent class analysis. Results yielded 4 classes. Members of the 4 classes were similar sociodemographically. Three classes of participants reported experiencing discrimination, and members of these classes had greater stress, higher rates of smoking and sleep disruption, and worse overall health than members of the class reporting no discrimination. Members of 2 classes made multiple, or intersectional, attributions for discrimination, and members of these classes reported the most frequent discrimination. Findings suggest that community members who are sociodemographically similar may have diverse discrimination experiences. Multilevel interventions that address multiple forms of discrimination (e.g., racism and sexism) may hold promise for reducing discrimination and, ultimately, health inequities within low‐resource urban community settings.     

Mental health consequences of weight cycling in the first-year post-treatment for breast cancer

Objectives: Weight cycling is linked with advanced breast cancer diagnosis, increased risk of cancer reoccurrence and cancer-related mortality. While women treated for breast cancer report challenges with navigating their post-treatment body shape and weight, the effects of weight cycling on body image and mental health have not been elucidated. This study examined associations between weight changes and weight cycling on psychological health (i.e. weight-related guilt, shame and depressive symptoms) among women in the first-year post-treatment.

Design and Outcome Measures: Self-reported assessments of pre-cancer weight cycling, post-treatment weight-related guilt, shame and depressive symptoms, and objective assessments of weight were assessed in a longitudinal sample of 173 women treated for breast cancer (M_age = 55.01 ± 10.96 years).

Results: Based on findings from multilevel models, women experienced the most weight-related shame when their weight was heavier than their personal average. Additionally, heavier weight was associated with worse psychological health, particularly for women with a history of stable (vs. cycling) weight pre-cancer.

Conclusions: Weight cycling pre-cancer and post-treatment weight change have important implications for psychological well-being. Due to the potential psychological consequences associated with a history of weight cycling, targeted strategies are needed to improve overall health outcomes for women’s survivorship after breast cancer.     

Relating Coalition Capacity to the Adoption of Science-Based Prevention in Communities: Evidence from a Randomized Trial of Communities That Care

Coalition‐based efforts that use a science‐based approach to prevention can improve the wellbeing of community youth. This study measured several coalition capacities that are hypothesized to facilitate the adoption of a science‐based approach to prevention in communities. Using data from 12 coalitions participating in a community‐randomized trial of the prevention strategy Communities That Care (CTC), this paper describes select measurement properties of five salient coalition capacities (member substantive knowledge of prevention, member acquisition of new skills, member attitudes toward CTC, organizational linkages, and influence on organizations), as reported by coalition members, and examines the degree to which these capacities facilitated the community leader reports of the community‐wide adoption of a science‐based approach to prevention. Findings indicated that the five coalition capacities could be reliably measured using coalition member reports. Meta‐regression analyses found that CTC had a greater impact on the adoption of a science‐based prevention approach in 12 matched pairs of control and CTC communities where the CTC coalition had greater member (new skill acquisition) and organizational capacities (organizational linkages).     

Perceived relationship with God moderates the relationship between social comparison and body appreciation

Social comparison has been shown to contribute to the negative attitudes that most Western women have towards their bodies. However, minimal research has addressed the relationship between social comparison and body appreciation, which entails holding favourable opinions towards the body, accepting the body along with its deviations from societal beauty ideals, respecting the body by engaging in healthy behaviours, and protecting the body by rejecting unrealistic media appearance ideals. This study tested whether feeling loved and accepted by God would weaken the inverse relationship between social comparison and body appreciation among a sample of 186 female undergraduates. Results showed that frequent body-related comparisons were related to lower body appreciation, but this relationship was conditional upon the quality of women's perceived relationship with God. Results suggest that future research should explore interventions designed to create improved secure attachment relationships between clients and God.     

Looking deathworthy: perceived stereotypicality of Black defendants predicts capital-sentencing outcomes

Researchers previously have investigated the role of race in capital sentencing, and in particular, whether the race of the defendant or victim influences the likelihood of a death sentence. In the present study, we examined whether the likelihood of being sentenced to death is influenced by the degree to which a Black defendant is perceived to have a stereotypically Black appearance. Controlling for a wide array of factors, we found that in cases involving a White victim, the more stereotypically Black a defendant is perceived to be, the more likely that person is to be sentenced to death.     

Children's understanding of reputations

In the present study, the authors investigated age differences in children's understanding (a) that a person's behavior may contribute to the formation of a shared opinion within the peer group and (b) that origins of a reputation can be direct or indirect. The authors read stories in which a target character engaged in either prosocial or antisocial interactions with peers to children in kindergarten, 2nd, and 4th grade. They then asked the children to judge how various peers viewed the target character. Children's explanations indicated that children in all of those age groups understood that firsthand experience influenced peers' opinions, and by 2nd grade, children understood that indirect experience or gossip also might have contributed to an individual's reputation.     

Turning configural processing upside down: part and whole body postures

Like faces, body postures are susceptible to an inversion effect in untrained viewers. The inversion effect may be indicative of configural processing, but what kind of configural processing is used for the recognition of body postures must be specified. The information available in the body stimulus was manipulated. The presence and magnitude of inversion effects were compared for body parts, scrambled bodies, and body halves relative to whole bodies and to corresponding conditions for faces and houses. Results suggest that configural body posture recognition relies on the structural hierarchy of body parts, not the parts themselves or a complete template match. Configural recognition of body postures based on information about the structural hierarchy of parts defines an important point on the configural processing continuum, between recognition based on first-order spatial relations and recognition based on holistic undifferentiated template matching.     

Grief Therapy and the Reconstruction of Meaning: From Principles to Practice

Viewed from a constructivist perspective, grieving is a process of reconstructing a world of meaning that has been challenged by loss. Although most people successfully navigate bereavement and retain or return to pre-loss levels of functioning, a significant proportion struggle with protracted grief, and are unable to find meaning in the wake of an unsought transition. For these individuals, constructivist therapists have a number of strategies at their disposal that foster meaning making and help clients reestablish a coherent self-narrative that integrates the loss, while also permitting their life story to move forward along new lines. After reviewing theory and evidence that scaffolds this constructivist conceptualization, this article draws on excerpts of therapy with two bereaved clients to illustrate how narrative retelling, therapeutic writing, a focus on metaphorical language, and the use of visualization can all be viable strategies in helping individuals reconstruct meaning in the wake of bereavement.     

Maternal Depressed Mood and Perceptions of Child Temperament

Research has suggested that women who experience postpartum depression are subsequently more likely to perceive their preschool-aged children as temperamentally difficult and maladjusted. However, previous studies have not controlled for the effects of concurrent depression levels on maternal ratings of child temperament or evaluated the accuracy of maternal reports. In the present study we assessed maternal and paternal ratings of child temperament 2 years after subjects had participated in a study of postpartum depression. The findings indicate that correlations between postpartum depression and subsequent child temperament ratings were accounted for statistically by concurrent levels of depression. Although fathers' ratings corroborated some aspects of maternal perceptions, levels of parental agreement were only moderately high. Moreover, discrepancies between the parents' reports were significantly associated with maternal depression, indicating that parental disagreement is more likely when the wife is dysphoric.
