追寻生命的意义：积极心理学视野下的乐观主义价值

乐观是当前西方积极心理学的核心概念和研究热点,有关乐观主义的价值问题凸显出了积极和消极的乐观主义两种对立的解释取向。事实上,乐观往往与悲观并行存在,乐观主义能否促进健康关键取决于对危机源刺激的过程性判断。有限度的现实乐观能够赋予个体独特的生命意义和价值,有助于个体在乐观与现实之间寻求到心理和谐和平衡的支点。当前的乐观研究已汇成了一股强劲的乐观主义潮流,必将成为心理世界发展新的生长点。     

Inherent biases in decision support systems: the influence of optimistic and pessimistic DSS on choice,affect, and attitudes

This study investigates the influence of a decision aid on decision makers' model‐based choices, emotions during the use of the model, and attitudes towards the model. A time allocation decision model was biased to purposefully provide optimistic or pessimistic criterion levels, on which subjects based their allocations. The results of our experiment indicate that the degree of “optimism” and “pessimism” inherent in the decision model had a significant impact on the decision maker's choices of criterion values, with optimism leading to higher criterion level choices and pessimism to lower levels. Furthermore, compared to pessimistic models, optimistic models significantly improved the decision makers' emotional states and, to some degree, their attitudes towards the decision aid. The implications of these conscious and sub‐conscious influences on decision makers' choices, emotions, and attitudes are discussed and the need for model‐builders and users to be aware of them is highlighted.

Global Progress I: Empirical Evidence for ongoing Increase in Quality-of-life

This paper argues that both the relativist and the pessimist critiques of the idea of progress are inadequate. Progress is defined as increase in global quality of life (QOL). Such QOL is intrinsically subjective, but not relative. It can be reliably measured through life satisfaction-type questions. The World Database of Happiness provides extensive data on social, economic and psychological factors that correlate with overall QOL. They include wealth, health, security, knowledge, freedom and equality. Various statistical data suggest that all these QOL indicators have undergone significant improvements during the last half century, in most of the world. This gives strong support to the thesis that progress objectively occurs.     

Expect the Best and Prepare for the Worst: Anticipatory Coping and Preparations for Y2K

The Y2K Bug, the programming glitch expected to derail computerized systems worldwide when the year changed from 1999 to 2000, provided a rich context for examining anticipatory coping and preparatory behaviors. In the last 2 months of 1999, 697 respondents completed an online survey of proactivity, worry about Y2K, dispositional optimism, primary and secondary control-oriented coping efforts, estimates of Y2K-related disruptions, and household preparations. Higher levels of proactivity, worry, and optimism were independently associated with greater self-reported preparations. These predictors were positively associated with greater primary control-oriented coping efforts, but showed differential relations to secondary control efforts, such as accepting the situation or trusting a higher power, especially among participants who thought the damage would be severe and lasting. Implications for understanding multiple ways of coping with potential stressors are discussed.

Parent Expectancies for Child Therapy: Assessment and Relation to Participation in Treatment

Two studies examined parents' pre-treatment expectancies for their child's psychotherapy among children (N = 405, ages 2–15) referred for oppositional, aggressive, and antisocial behavior. Study I focused on the development of a measure to assess expectancies. The results indicated that the measure was internally consistent. Moreover, socioeconomic disadvantage and ethnic minority status, severity of child dysfunction, child age, and parental stress and depression were significant predictors of lower parent expectancies for child therapy. Study II examined the relation of parent expectancies and participation in therapy. The results indicated that parent expectancies predicted subsequent barriers to treatment participation, treatment attendance, and premature termination from therapy. Overall, these findings have implications for the study of expectancies for therapy, for identifying families at risk for premature termination from treatment, and for the development of interventions designed to increase parent participation in child therapy.     

Hope for the Worst: Occasional Reinforced Extinction and Expectancy Violation in the Treatment of OCD

An inhibitory learning conceptualization of treatment mechanisms in exposure-based therapy appears to better account for durability of symptom reduction and index overall learning. Presented here is an overview of two core elements of inhibitory learning, expectancy violation and occasional reinforced extinction, as they are thought to function in exposure and response prevention (ERP) for OCD. The overview is then followed by case examples illustrating these processes at work in a naturalistic clinical setting. Implications for treatment are broadly discussed.     

Two routes toward optimism: how agentic and communal themes in autobiographical memories guide optimism for the future

Autobiographical memories are particularly adaptive because they function not only to preserve the past, but also to direct our future thoughts and behaviours. Two studies were conducted to examine how communal and agentic themes of positive autobiographical memories differentially predicted the route from autobiographical memories to optimism for the future. Across two studies, results revealed that the degree to which participants focused on communal themes in their autobiographical memories predicted their experience of nostalgia. In turn, the experience of nostalgia increased participants’ levels of self-esteem and in turn, optimism for the future. By contrast, the degree to which participants focused on agentic themes in their memories predicted self-esteem and optimism, operating outside the experience of nostalgia. These effects remained even after controlling for self-focused attention. Together, these studies provide greater understanding of the interrelations among autobiographical memory, self-concept, and time, and demonstrate how agency and communion operate to influence perceptions of one’s future when thinking about the past.     

Individual differences in the preference for worked examples: Lessons from an application of dispositional learning analytics

Worked-examples have been established as an effective instructional format in problem-solving practices. However, less is known about variations in the use of worked examples across individuals at different stages in their learning process in student-centred learning contexts. This study investigates different profiles of students' learning behaviours based on clustering learning dispositions, prior knowledge, and the choice of feedback strategies in a naturalistic setting. The study was conducted on 1,072 students over an 8-week long introductory mathematics course in a blended instructional format. While practising exercises in a digital learning environment, students can opt for tutored problem solving, untutored problem solving, or call worked examples. The results indicated six distinct profiles of learners regarding their feedback preferences in different learning phases. Finally, we investigated antecedents and consequences of these profiles and investigated the adequacy of used feedback strategies concerning ‘help-abuse’. This research indicates that the use of instructional scaffolds as worked-examples or hints and the efficiency of that use differs from student to student, making the attempt to find patterns at an overall level a hazardous endeavour.     

Get the Message: Targeting Beliefs to Develop Risk Reduction Intervention Messages for African American Adolescents

Risk reduction interventions that promote condom use, a vital component of most HIV prevention interventions, have been successful in increasing condom use among African American adolescents. Understanding theoretical components that lead to behavior change and selecting relevant risk reduction messages remain important considerations for targeting new interventions and tailoring existing interventions. The present study sought to (1) identify the most important theoretical determinants of condom use intention in African American adolescent males and females, separately, using the integrative model of behavior prediction, and (2) identify underlying beliefs within the determinants that were good candidates for message development in similar interventions. Using 446 African American adolescents, multi‐group SEM indicated that the gender‐specific IM exhibited a better fit than the overall model. Specifically, the IM had a stronger capacity for predicting condom use intention and condom use behavior for adolescent boys. Using a specific criteria for message selection, specific condom use beliefs were discussed as potential candidate messages for both African American males and females.     

Optimism and Mental Health in Adolescence: a Prospective Validation Study of the Dutch Life-Orientation Test-Revised (LOT-R-A) for Adolescents

The study aimed to examine the psychometric properties of the Dutch Life Orientation Test-Revised for Adolescents (LOT-R-A), a self-report questionnaire assessing dispositional optimism, and to evaluate the two-factor structure (optimism, pessimism). The LOT-R-A and the questionnaires measuring well-being (MHC-SF-A) and psychological problems (SDQ) were completed by 459 Dutch adolescents (178 boys and 281 girls) between the ages of 11 and 18 years at baseline and 281 adolescents at a four-week follow-up. The results confirmed the two-factor structure (optimism, pessimism) of the LOT-R-A. The findings provided evidence of internal consistency of scores ranging from low to good, and evidence of good test-retest reliability of scores. Further, scores of optimism were cross-sectionally positively associated with scores of positive emotions and well-being and negatively with scores of psychological problems and negative emotions, providing evidence of convergent and divergent validity of optimism scores with emotions, well-being, and psychological problems. Lastly, scores of optimism were prospectively positively associated with scores of well-being and negatively with scores of psychological problems, providing evidence of criterion validity of optimism scores with well-being and psychological problems. Based on these findings it can be concluded that the LOT-R-A is a valid instrument to examine optimism among adolescents. Future research can help to elucidate the role of optimism in mental health interventions and can gather knowledge on how these interventions can be refined to optimally cultivate optimism during the developmental period of adolescence.     

Investing in the real me: Preference for experiential to material purchases driven by the motivation to search for true self-knowledge

One mechanism underlying the hedonic benefits of experiential purchases is that one’s core self is more centrally reflected in experiential purchases. However, little is known about whether people consume experiential purchases as a means of discovering their true self. The present research explored the possibility that people value experiential purchases as a potential tool for understanding their true self. Consistent with the hypothesis, Study 1 demonstrated that experiential purchases were perceived to be a more valuable source of gaining knowledge about one’s true self compared to material purchases. Using correlational methods, Study 2 found that the motivation to search for true self-knowledge positively predicted preference for experiential purchases over material purchases. Finally, Study 3 showed a causal effect of motivation to search for true self-knowledge on a tendency to prefer experiential purchases to material purchases. Implications and future directions for well-being research and marketing are discussed.     

Attending to emotional expressions: no evidence for automatic capture in the dot-probe task

Research on automatic attention to emotional faces offers mixed results. Therefore we examined validity effects for facial expressions of different emotions (compared to neutral faces) with a dot-probe paradigm in seven studies (total N?=?308). Systematic variations of type of emotion, CTI, task, cue size, and masking allow for a differentiated assessment of attentional capture by emotions and possible moderating factors. Results indicate a general absence of emotional validity effects as well as a lack of significant interactions with either of the manipulated factors, indicating that facial expressions of emotions do not capture attention in a fully automatic fashion. These findings suggest that situational and contextual factors have to be taken into account when investigating attentional capture of emotional faces.     

Social incentives for gender differences in the propensity to initiate negotiations: Sometimes it does hurt to ask

Four experiments show that gender differences in the propensity to initiate negotiations may be explained by differential treatment of men and women when they attempt to negotiate. In Experiments 1 and 2, participants evaluated written accounts of candidates who did or did not initiate negotiations for higher compensation. Evaluators penalized female candidates more than male candidates for initiating negotiations. In Experiment 3, participants evaluated videotapes of candidates who accepted compensation offers or initiated negotiations. Male evaluators penalized female candidates more than male candidates for initiating negotiations; female evaluators penalized all candidates for initiating negotiations. Perceptions of niceness and demandingness explained resistance to female negotiators. In Experiment 4, participants adopted the candidate’s perspective and assessed whether to initiate negotiations in same scenario used in Experiment 3. With male evaluators, women were less inclined than men to negotiate, and nervousness explained this effect. There was no gender difference when evaluator was female.     

Bystander training for faculty: A promising approach to tackling microaggressions in the academy

Microaggressions present significant barriers to entry and advancement for faculty from traditionally marginalized groups, yet workplace interventions to stymy them remain undocumented in the literature. The purpose of this study was to evaluate the impact of bystander training to deal with subtle expressions of bias in the academic workplace. We developed a 2-h interactive bystander training workshop that specifically addressed intervening in microaggressions university faculty experience; approximately 21% of the full-time faculty participated in the training. Results indicate that post workshop, participants endorsed higher levels of likelihood of bystander intervention and higher levels of bystander efficacy to deal with microaggressive events (compared to pre-test 4 days before the workshop); scores on these measures remained significantly greater than pre-test at both 6-week and 12-week follow-up. Furthermore, preliminary evidence suggests that both likelihood of bystander intervention and bystander efficacy scores predicted self-reported bystander behavior at both 6 and 12 week follow up. These findings suggest that bystander training may be a promising approach to tackling microaggressions faculty experience in higher education.     

Resort to faith-healing practices in the pathway to care for mental illness: a study on psychiatric inpatients in Orissa

Belief in supernatural causation of mental illnesses and resort to faith healing as the method of intervention continue in many parts of the world. This study intended to find out the belief and utilisation of faith-healing, its implications, and associated socio-cultural factors in a sample of psychiatric inpatients in Orissa, an eastern state of India. It was found that the majority (85.5%) of the patients believed in supernatural causation, 75% attended faith healing before seeking medical help, and a considerable proportion had related psychopathology and continued to believe in the therapeutic efficacy of the faith healing, even while continuing medicinal treatment. Resort to faith-healing effectively delayed medical intervention to an extent in many patients and some of the faith-healing methods were traumatising. These observations raised concern. A considerable proportion of patients and families found faith healing supportive, reassuring, and more acceptable in the community. Sensitivity to these belief systems and faith healing practices is important for practising mental-health professionals.     

Responding to the embodiment of distress in individuals defined as obese: Implications for research

This article examines the evidence for a relationship between body image distress (BID) and obesity, and between emotional eating and obesity. The need is highlighted for treatment programmes that are responsive to these complex issues and combine this with diet and physical activity. Weight loss programmes so far have had a poor success rate. They have often sought to capitalise on BID as a motivation to lose weight, but there is some evidence that such an emphasis may be self‐defeating, as seriously overweight individuals may eat either to self‐punish or self‐comfort and may also avoid social situations that could support healthy lifestyles. The case is made for new research that addresses the highlighted psychological aspects of obesity. There is a need for both a randomised controlled trial (RCT) that will enable a statistical inference of causality relating to new treatments and qualitative, interview‐based research to elicit information regarding individual responses to treatment. Dance Movement Therapy (DMT) is proposed as one new treatment option for those individuals whose obesity is linked to emotional eating. Theoretical support and empirical research evidence for DMT are explored. However, since this treatment has not so far been applied with obese individuals, a pilot study is proposed prior to a RCT.     

Council-Based Approaches to Intimate Partner Violence: Evidence for Distal Change in the System Response

Communities across the United States are collaborating to create a coordinated response to intimate partner violence (IPV); ideally, this involves promoting best practices in the justice and human service systems and engaging a broad array of community sectors (e.g., human service; criminal justice; faith; business; education) to promote victim safety and batterer accountability (Pence, 1999). The current study examined the extent to which Family Violence Coordinating Councils resulted in change in the systems’ response to IPV. Specifically, we examined judicial order of protection data from 1990 to 2005 to establish whether the formation and development of councils across the state of Illinois promoted the issuance of plenary orders of protection following the initial granting of emergency orders of protection. Such a pattern would indicate implementation of a best practice in the system response to IPV. Utilizing a multilevel logistic modeling approach, we found that the introduction and development of councils was indeed related to the accessibility of plenary orders of protection. The specific ways in which councils may have influenced such an outcome and the implications of this approach for research on council effectiveness are discussed.     

Hybrid search in context: How to search for vegetables in the produce section and cereal in the cereal aisle

ABSTRACT

The own race bias (ORB) refers to a finding that faces of members of one's own racial or ethnic group are easier to recognize. Holistic processing theories suggest that the ORB might be moderated by viewing distance. Participants studied photographs of own and other race individuals and then took a recognition memory test. Viewing distance was simulated by varying the degree to which photographs were blurred (Experiment 1) and by varying photograph size (Experiment 2). Findings indicated that own race faces were better recognized, that recognition was impaired by simulated viewing distance, but the size of the ORB was not contingent upon distance.
