Gambling near‐misses are non‐rewarded events that resemble a winning configuration. Past research using slot machines has shown that moderate rates of near‐misses increase gambling persistence, but the mechanisms supporting this persistence are unclear. One hypothesis is that near‐misses are mistakenly interpreted as signals of skill acquisition, supporting learning and fuelling the ‘illusion of control’. A slot machine simulation was administered to 60 volunteers, with ratings of the perceived chances of winning, pleasure and motivation to play following particular outcomes. Psychophysiological measures (electrodermal activity and heart rate) were taken, and gambling persistence was measured after 30 trials. Near‐misses were similar to full‐miss outcomes in that they were regarded as unpleasant. However, near‐misses were akin to win outcomes in that they increased motivations to play and electrodermal activity. Learning was evidenced by the expectancy of winning increasing following wins and decreasing after losses. Although there was no overall change in expectancy of winning after near‐misses across all participants, those subjects reporting a greater increase in the expectancy of winning following a near‐miss showed more persistent play, consistent with the learning hypothesis. Greater heart rate acceleration following near‐misses was also associated with persistence. We also observed differential effects of near‐misses where the reel stopped either side of the winning position (‘payline’): motivational effects were restricted to near‐misses stopping before the payline, whereas near‐misses that stopped after the payline were primarily aversive. The payline effects are not predicted by the learning hypothesis and may indicate an affective component to near‐misses, possibly linked to counterfactual processing.

This work examines ways to make the best use of limited resources when selecting individuals to follow up in a longitudinal study estimating causal effects. In the setting under consideration, covariate information is available for all individuals but outcomes have not yet been collected and may be expensive to gather, and thus only a subset of the comparison participants are followed. Expressions in Rubin and Thomas (1996) show the benefits that can be obtained, in terms of reduced bias and variance of the estimated treatment effect, of selecting comparison individuals well matched to those in the treated group compared with a random sample of comparison individuals. We primarily consider nonexperimental settings but also consider implications for randomized trials. The methods are illustrated using data from the Johns Hopkins University Baltimore Prevention Program, which included data collection from age 6 to young adulthood of participants in an evaluation of 2 early elementary-school-based universal prevention programs. 相似文献

Adolescent sexual assault survivors are more likely to seek support from peers and families than to formal help systems, such as the medical and legal systems. In this study, we conducted in-depth qualitative interviews with N = 20 adolescent sexual assault survivors aged 14–17 who obtained services from Sexual Assault Nurse Examiner Programs to understand the pathways that led them to seek formal help. Our goal was to examine how survivors’ initial disclosures to peers, families, and schools facilitated adolescents’ access to formal help systems. Additionally, we explored how peer, family and school systems interact as mesosystems to effect subsequent disclosures. Results show that the peer and family microsystems were decisive in survivors’ willingness to enter formal systems. Disclosure became more complex when peer, family, and school personnel all became aware of the assault. When these mesosystem interactions occurred with survivors’ consent and produced a helpful response, they were perceived as positive. Alternatively, mesosystem interactions in which survivors had minimal control resulted in greater reluctance to enter formal systems. These conclusions highlight the need educating informal support providers about community services in order to make the disclosure process easier and beneficial for survivors’ recovery and well-being. 相似文献

Implementation intentions, plans relating to when and where behaviours will be performed, have been effective in increasing health behaviour. Two studies are reported that test the impact of this strategy in promoting breast self-examination (BSE), a behaviour shown to aid the early detection of tumours. In study 1, 457 participants were randomly allocated to either implementation intention or control conditions. Implementation intentions significantly increased the likelihood of BSE at one month. The effect of the intervention was marginally significant at six months. Study 2 (N?=?101) tested the efficacy of a collaborative implementation intention intervention that required female participants to plan, with a partner, collaborative BSE performance. Results indicated that both implementation intentions and partner involvement were associated with BSE performance at one month, whilst the collaborative implementation intention intervention showed a 100% success rate. Collaborative implementation intentions may reduce forgetfulness. Interventions that encourage partner involvement in planning and enacting behaviour appear to enhance implementation intention utility. 相似文献

The demise of Christendom is of fundamental significance in understanding the present and future relationship between the churches and European culture. Attempts to develop post-Christendom perspectives are hindered by linguistic and conceptual confusion. This article explores misleading implications of the terms ‘post-Constantinian’ and ‘post-Christian’ and argues for the consistent use of the term ‘post-Christendom’. Use of the terms ‘Christendom’ and ‘post-Christendom’ has been criticised for failing to differentiate between different kinds of Church–state partnerships, some of which may be less problematic than others. This article acknowledges such historical differences but argues that there is an underlying ideological unity susceptible of being described and investigated under these labels. It argues further that attempts to promote a benign expression of Christendom as a possible future for Europe are unwise. It summarises the transitions occurring as Europe journeys beyond Christendom and argues for creative engagement with post-Christendom as an opportunity for ecclesial renewal. 相似文献

Parent–child reminiscing conversations in early childhood have received theoretical attention as a forum for children's self‐concept development, but this has been little addressed in empirical work. This study examines associations between emotion reminiscing and children's self‐concepts and, building from the reminiscing and personality development literatures, also explores the role of children's coping. Sixty 4‐ and 5‐year‐old children and their mothers completed reminiscing conversations about events in which the child had experienced negative emotion, children completed an age‐appropriate assessment of their self‐concept, and mothers and teachers reported on children's coping strategies. Children's self‐perceived timidity was associated with their explanations for negative emotions during reminiscing. Children's self‐perceived negative affect was associated with fewer emotion resolutions during reminiscing, and with distinctive patterns of coping. Both reminiscing and coping made unique contributions to children's self‐concepts, and findings also suggest that coping may in some contexts indirectly connect reminiscing with self‐concept. These findings suggest that reminiscing conversations both reflect children's characteristics and provide a context for learning about their characteristics, along with strategies for emotion management.

Abstract This paper investigates athletes' perception of the relationship between cognitive interference and its effects on concentration and effort during sport performance. The sample consisted of 115 volleyball players that took part in a national university tournament. Three different kinds of thoughts were investigated: ‘performance worries’, ‘situation-irrelevant thoughts’, and ‘thoughts of escape’. Path analysis was used to examine the relationships. All kinds of thoughts were reported to be detrimental to concentration, whereas different patterns of associations emerged between different thoughts and subsequent effort. ‘Performance worries’ were reported to be related to increases in effort for athletes holding higher goal attainment expectancies and decreases in effort for athletes holding lower goal attainment expectancies. ‘Thoughts of escape’ were reported to be related to decreases in effort, while no significant relation between ‘situation irrelevant thoughts’ and effort emerged. Results stress the importance of further examining the role of interfering thoughts athletes experience during competition. 相似文献

Childhood abuse and dating violence victimization are prevalent and devastating problems. Although there has been an abundance of research on these topics in recent years, researchers and institutional review boards often struggle with determining whether asking respondents questions on previous violence will result in increased emotional distress or other negative research outcomes. Empirical data are therefore needed that examine the research reactions of individuals who participate in research on childhood abuse and dating violence. This study examined this topic among a sample of male college students (N?=?193). Results showed that victims of childhood sexual abuse had more negative emotional reactions and victims of physical dating violence had more negative perceived drawbacks to research participation than nonvictims. However, victims and nonvictims did not differ on positive research reactions. These findings suggest that there are few differences between victims and nonvictims on research reactions. 相似文献

Abstract This study, derived from the work of Hinkle (1965), explored the short-term test-re-test stability of two forms of Implications for Change grids. In the Single Self implications task, persons considered whether a general self change on one personal construct dimension would influence change on their other dimensions. The Multiple Self implications task followed the same form of questioning. However, in this latter procedure, persons were asked about self change within more specific contexts of activity (e.g., self as friend, self at play). Average consistency levels were calculated for the Single Self and the Multiple Self grids. Predictions were made regarding which subjects would show more or less consistency using measures of self meaningfulness and construct organization at first testing 相似文献

A gap exists in the literature with regard to the theoretical conceptualization of nonoffending parental and other caregiver (NOC) support of sexually abused children. Measures need to be developed that appropriately capture this construct. The purpose of this article is to present a qualitative study that asked 17 NOCs in different ways how they supported their sexually abused children after the disclosure of the sexual abuse. The multiple different types of support were coded and, using grounded theory, the structure of NOC support emerged from the data. The final structure of NOC support had 8 dimensions, including basic needs, safety and protection, decision making, active parenting, instrumental support, availability, sensitivity to child, and affirmation. 相似文献
