Traditionally, near-miss events in games of skill provide feedback to an individual regarding his or her performance. However, in games of chance, like slot machine gambling, the use fails to carry over. A near miss in slot machine gambling may still be endorsed when most of the symbols falling on a payline match, though technically this arrangement provides no real measure of skill or progress. To date, attempts to study the near miss in slot machine gambling have used resistance to extinction and preference assessment preparations, both of which unsuccessfully capture any putative reinforcement properties. The current investigation introduces a new methodology to assess putative conditioned reinforcement properties of stimuli correlated with the near miss in simulated slot machine gambling by incorporating the observing response with concurrently available schedules, termed simultaneous observing. Successful tests of the methodology regarding schedule-correlated stimuli in relation to win rates demonstrate its potential use, and failure to identify a near-miss event as producing reinforcing effects for schedule-correlated stimuli adds credibility to its ability to discriminate between functions.

The theorization and empirical exploration of contextual effects is a long‐standing feature of public opinion and political behavior research. At present, however, there is little to no evidence that citizens actually perceive the local contextual factors theorized to influence their attitudes and behaviors. In this article, we focus on two of the most prevalent contextual factors appearing in theories—racial/ethnic and economic context—to investigate whether citizens' perceptions of their local ethnic and economic contexts map onto variation in the actual ethnic composition and economic health of these environments. Using national survey data combined with Census data, and focusing on the popular topics of immigration and unemployment, we find that objective measures of the size of the immigrant population and unemployment rate in respondents' county and zip code strongly predict perceived levels of local immigration and assessments of the health of one's local job market. In addition to demonstrating that citizens are “receiving the treatment,” we show that perceptions of one's context overwhelmingly mediate the effect of these objective contextual factors on relevant economic and immigration attitudes. The results from our analyses provide scholars with unprecedented evidence that a key perceptual process presumed in various contextual theories of political attitudes and behavior is, in fact, valid.  相似文献

Research has demonstrated strong but independent attention to the role of self-control and street code attitudes in predicting criminal and violent behavior. Yet, there are good theoretical notions to believe that street code attitudes may be a salient mechanism in the self-control–offending relationship. Specifically, the present study investigates: (1) the extent to which self-control predicts adopting street code attitudes and (2) whether street code attitudes mediate the effect of self-control on criminal behavior. Using data collected from a multisite sample of over 900 young adults, we assess this mediation hypothesis for three distinct types of criminal activity: violent, property, and drug use. Our results reveal that individuals with lower self-control are more likely to adopt street code attitudes, that self-control is related to all three forms of offending, and that street code attitudes fully mediate the effect of self-control on violence, partially on property crime, but not in the case of drug use. Findings and directions for future research are discussed.  相似文献

With data gathered from 47 university counseling centers in the United States, this study addresses both inter- and intra-group differences in symptomatology at intake among international students. In Study 1, symptomatology among international students was explored in comparison to US ethnic groups. In Study 2, intra-group differences in symptomatology among international students were examined. In Study 1, data consisted of 14,421 international, White American, African American, Asian American, and Latina/Latino American counseling center clients who completed the CCAPS-62 at intake. Partially supporting our hypothesis, results indicate significant findings among international students in the social anxiety and academic distress domains of the CCAPS-62. Contrary to our expectations, Asian American students reported significantly greater concerns across many domains when compared to other groups. In Study 2, international students (n = 607) were further divided into five continents of origin: Asia, Africa, North America, South America, and Europe. Results indicate that in multiple domains, international students from Asia and Africa reported significantly greater concerns than those from Europe, North America, or South America. Implications of findings for university counseling centers and universities at large are discussed.  相似文献

Problematic drinking has long been established as an important antecedent to the perpetration of intimate partner violence (IPV). As little research has evaluated individual differences beyond anger in this association, this research examines problematic drinking and IPV perpetration through the lens of self-determination theory (SDT), the relational perspective suggesting individuals are motivated to be in their relationship for autonomous (i.e., self-driven) and controlled (i.e., guilt-driven) reasons. We test the hypothesis that problematic drinking is more strongly associated with IPV among those who are controlled in their motivation in four independent samples (N?=?617). College students in relationships completed measures of alcohol consumption, negative alcohol-related consequences, relationship motivation, and IPV perpetration. Results generally suggested that the association between both alcohol consumption and negative alcohol-related consequences and IPV perpetration is only significant among those endorsing greater controlled motivation. This study supports problematic drinking as not being an equal risk factor for all individuals, and suggests that some people may be more vulnerable to problematic drinking resulting in relationship aggression.  相似文献

This article explores how gender shapes patterns of interaction in webcam sex work. Analysis of 40 hours of cyberethnographic data shows that workers’ degree of professionalism, rather than their gender, shapes behavior in webcam sex work. This article identifies three patterns exhibited by both female and male professional broadcasters but not by their less professional counterparts: sharing personal information, deferring to the wishes of clients, and conducting dynamic performances. This article contributes to sex work literature by documenting webcam sex work as a new sector of the sex industry and by reassessing how gender matters in sex work.  相似文献

The lexicality effect in verbal short-term memory (STM), in which word lists are better recalled than nonwords lists, is considered to reflect the influence of linguistic long-term memory (LTM) knowledge on verbal STM performance. The locus of this effect remains, however, a matter of debate. The redintegrative account considers that degrading phonological traces of memoranda are reconstructed at recall by selecting lexical LTM representations that match the phonological traces. According to a strong version of this account, redintegrative processes should be strongly reduced in recognition paradigms, leading to reduced LTM effects. We tested this prediction by contrasting word and nonword memoranda in a fast encoding probe recognition paradigm. We observed a very strong lexicality effect, with better and faster recognition performance for words as compared to nonwords. These results do not support a strong version of the redintegrative account of LTM effects in STM which considers that these LTM effects would be the exclusive product of reconstruction mechanisms. If redintegration processes intervene in STM recognition tasks, they must be very fast, which at the same time provides support for models considering direct activation of lexico-semantic knowledge during verbal STM tasks.  相似文献

Despite interest in psychosocial vulnerabilities to depression, little is known about reliable and valid individualized risk profiles that can be used to match individuals to evidence-based interventions for depression. This study investigated well-established cognitive and interpersonal vulnerabilities to depression among youth to discern an evidence-based risk classification approach which is being used in a personalized depression prevention randomized clinical trial. Data were drawn from a general community sample of adolescents (N?=?467; ages 10–16, mean 13.14, SD?=?1.62; 57% females) who were followed prospectively for 3 years. Youth completed measures of cognitive (negative cognitive style, dysfunctional attitudes, rumination) and interpersonal (support and conflict with peers and parents, excessive reassurance seeking, social competence, co-rumination) risks to depression, and then were followed longitudinally for onset of depression. Principal axis factor analyses showed that three latent factors--cognitive vulnerability, interpersonal support, and interpersonal conflict--optimally represented the structure of these risk factors. Clinically practical and meaningful cutoffs, based on tertile cut-off scores on cognitive and interpersonal risk measures, were used to categorize youth into relatively balanced high and low cognitive and interpersonal risk groups. These risk classification groups exhibited validity (AUC?>?0.70) by predicting prospective onsets of depressive episodes at 18-months follow-ups. These findings demonstrate a reliable and valid approach to synthesize psychosocial vulnerabilities to depression, specifically cognitive and interpersonal risks. Results are discussed in terms of using these risk classifications profiles to test personalized prevention of depression during adolescence.  相似文献
