Gambling studies have described a “near-miss effect” wherein the experience of almost winning increases gambling persistence. The near-miss has been proposed to inflate the value of preceding actions through its perceptual similarity to wins. We demonstrate here, however, that it acts as a conditioned stimulus to positively or negatively influence valuation, dependent on reward expectation and cognitive engagement. When subjects are asked to choose between two simulated slot machines, near-misses increase valuation of machines with a low payout rate, whereas they decrease valuation of high payout machines. This contextual effect impairs decisions and persists regardless of manipulations to outcome feedback or financial incentive provided for good performance. It is consistent with proposals that near-misses cause frustration when wins are expected, and we propose that it increases choice stochasticity and overrides avoidance of low-valued options. Intriguingly, the near-miss effect disappears when subjects are required to explicitly value machines by placing bets, rather than choosing between them. We propose that this task increases cognitive engagement and recruits participation of brain regions involved in cognitive processing, causing inhibition of otherwise dominant systems of decision-making. Our results reveal that only implicit, rather than explicit strategies of decision-making are affected by near-misses, and that the brain can fluidly shift between these strategies according to task demands.  相似文献

Eye-tracking was used to investigate whether gaze direction would influence the visual scanning of faces, when presented in the context of a full character, in different social settings, and with different task demands. Participants viewed individual computer agents against either a blank background or a bar scene setting, during both a free-viewing task and an attractiveness rating task for each character. Faces with a direct gaze were viewed longer than faces with an averted gaze regardless of body context, social settings, and task demands. Additionally, participants evaluated characters with a direct gaze as more attractive than characters with an averted gaze. These results, obtained with pictures of computer agents rather than real people, suggest that direct gaze is a powerful attention grabbing stimulus that is robust to background context or task demands.  相似文献

This paper offers some speculative discussion about the current state of the “omnivore” debate, instigated by Richard A. Peterson. It argues that debates about the social patterning of tastes need to take greater account of changed practices of cultural production as well as consumption through the identification of two “stories of abundance” in the cultural realm. The first relates to accounts of the changing and expanding cultural industries, whilst the second considers the rich variety of widely available culture enabled by various technologies of distribution. Taking these stories into account, the paper argues that sociological analyses of cultural hierarchy might lag behind those that are mundane and everyday to both cultural producers and consumers and that an orientation to culture that ranges across established hierarchies is increasingly unremarkable. Such a change is related to the structural and discursive means through which culture is circulated. The paper concludes that cultural analysts need to modify their theoretical models and their methodological approaches to better reflect a variegated field of culture and a more fluid cultural hierarchy. In the tradition of both Peterson and Bourdieu, contemporary analyses of patterns of cultural consumption and taste need to take fuller account of the ways in which culture is produced, circulated and valued if they are to maintain their explanatory power.  相似文献

Abstract

This paper provides an overview of assessing the effectiveness of newly legislated social policies. In an era of growing public reliance on faith-based social services, it is imperative to be accountable and assess the efficacy and effectiveness of this set of providers. It discusses the paucity of such attempts and the complications involved in measuring effectiveness of social programs, especially when religion is involved. It then reviews the contributions provided in this volume and draws conclusions for future Studies.  相似文献

This article looks at the representation of scale in the 2014 film The Theory of Everything, identifying moments that relate to three concerns: firstly, how disabled people experience scale issues at an all too practical level in daily life; secondly, how Hawking’s experience of scale at the level of both body and mind is (a)typical of the way it is experienced by disabled people generally; and, thirdly, how a focus on the film can prompt some rethinking of perspectives both within disability studies and within the conceptualisation of scale more broadly.  相似文献

Abstract

The article presents a cross-cultural comparison of stepfamilies. Israeli and American stepfamilies were compared. The samples were similar in socio-demographic characteristics. Using translations of the same instruments, Israeli and American samples were compared for past orientation, acceptance/rejection of difference from non-stepfamilies, focal sub-system, satisfaction and functioning. Similarities and differences between American and Israeli stepfamilies are presented and their association to characteristics of the two societies are discussed. Methodological aspects of conducting cross-cultural research are addressed and directions for future research are suggested.  相似文献

This article gives an overview of research on Super's theory across cultures within the United States as well as internationally. Research indicates that the theory has some cross-cultural validity, yet there seem to be measurement concerns. The article also discusses two areas for future investigation: development of ethnic identity as a vocational task and research on developmental contextualism (Vondracek, Lerner, & Shulenberg, 1986).  相似文献

Constrict theory states that, in the short run, ethnic diversity in any context lowers both the quantity and the quality of interpersonal contacts. We test this theory in the school context, expecting that ethnic school diversity yields fewer and lower quality friendships. Moreover, we investigate whether the associations hold when controlling for the school's socioeconomic situation, and whether the relations between ethnic school diversity and the social outcomes differ between natives and immigrants. Multilevel analyses on data from the Flemish Educational Assessment, consisting of 10,546 natives and 1,324 immigrants in 85 secondary schools, show that ethnic diversity yields fewer friendships and a lower attachment to friends. However, this appears to be due to the schools’ socioeconomic composition. For immigrants, moreover, a higher ethnic diversity yields more friendships and a higher attachment to friends. Implications for theory and practice are discussed.  相似文献

The regulations of the Privacy Act of 1974 have had far-reaching effects on Federal Agencies and on their record keeping practices. This article discusses the impact on one counselor and the culminating development of the unique interviewing technique of openly sharing the written record with the client which answers the patient's age-old question of what the therapist is thinking about him and his problems.  相似文献

This article, and an earlier linked one, focus on the labour process of the modern Western female prostitute. Drawing on available qualitative research from the United Kingdom and Australia, and research undertaken by one of the authors in New South Wales, we argue here that the ways in which individual prostitutes understand themselves, the work that they do and their relationships with clients are at least partly informed by the discursive context of their labour. We seek to highlight the variety of discourses which currently give shape to prostitution in the modern West, and in so doing discuss the ways in which individual workers may engage with these discourses to make sense of their life‐world — for example, whether they understand themselves as victims of patriarchy or as feminist activists. In this second article, then, our focus moves from the encounter between the client and the prostitute to the prostitute's career, and we provide a discussion of the various ways of understanding how and why prostitutes enter the profession, how and why they stay in it, how and why they exit this occupational field and how and why they understand themselves in particular ways following such an exit.  相似文献

The persisting disparity in college graduation rates along racial and ethnic lines combined with growing Latina/o college‐age population has compelled an increasing number of researchers to examine inequalities in higher education outcomes. Some of these researchers have attempted to better understand Latina/o college experiences by researching Latina/o Greek life. In this article, I review the literature on Latina/o sororities and fraternities. I identify four approaches in the scholarship: Latina/o student development through campus involvement, Latina/o ethnic identity development through sorority or fraternity participation, finding cultural congruence in sorority and fraternity membership, and perceived discrimination and racial climates in college. This article reveals that scholarship about Latina/o Greek life examining race and racism is severely limited. Given the scope of existing work, I suggest that analysts have examined “everything but racism.” I conclude by highlighting some of the research on higher education that centers race and ethnicity as an analytical focus, demonstrating deeply embedded processes that impact Latina/o college student success. I argue that research about race and racism in college points to significant opportunities for researchers seeking to examine how Latinas/os navigate such environments, as Greek life is woven into the social and academic fabric of higher education institutions.  相似文献
