Using a computer simulation of three slot machines to investigate a gambler’s preference among varying densities of near-miss alternatives

The present article describes a software program in Visual Basic .NET designed to simulate three slot machines on a computer screen. This software is described in detail regarding utility, downloading, and usage; and data are presented illustrating the software’s potential for researchers interested in gambling behavior. A simulation of multiple slot machines such as this enables researchers to evaluate players’ preferences across various machines. In the highlighted experiment, 18 recreational slot machine players played the software for extra course credit and a chance at cash prizes. All participants played a version of the simulation in which every 5th response on average was a win, whereas the remaining trials were a loss. However, on those loss trials, a varying distribution of almost wins or near misses (i.e., two winning symbols on the payoff line and the final winning symbol directly above or below the payoff line) were presented in percentages of 15, 30, or 45. While no preferences across the three options could be predicted on the basis of reinforcement history alone, deviations from equal choices across the games were noted and appeared to be the result of the presentations of near-miss losing trials. Implications for a greater understanding of pathological gambling are presented.     

Determinants of Depression Severity and Duration in Canadian Adults: The Moderating Effects of Gender and Social Support

This study examined the effects of 4 subtypes of social support (tangible, affective, positive social interaction, and emotional/informational) and gender on the severity and duration of depressive symptoms within the general adult Canadian population. Data were collected from the Canadian Community Health Survey (CCHS; Statistics Canada, 2002 ). Upon meeting predetermined criteria, 6,316 participants were included in the study. The findings suggest that, overall, positive social interaction was significantly associated with decreases in depression severity; while emotional/informational support was significantly associated with increases in depression severity. Positive social interaction and emotional/informational support appeared to significantly decrease the duration of depression. Interesting gender differences also emerged among the 4 subtypes of social support. Implications of the findings are discussed.     

Racial disparities in mental health service use by adolescents who thought about or attempted suicide

Differences in rates and predictors of mental health service use among 2,226 Black, Hispanic, and White adolescents (aged 12-17) who reported recent suicidal thoughts or an attempt were examined. Black adolescents were 65% (OR = .65, p < .05), and Hispanic adolescents were 55% (OR = .55, p < .001), as likely as White adolescents to report service use, even when controlling for need for care and ability to secure services. Suicide attempt and psychiatric symptoms each interacted with race to increase the odds of service use uniquely for White adolescents. Results indicate that racial disparities characterize adolescents' mental health service use even when suicide risk increases.     

The Multidimensional Scale of Perceived Social Support: Analyses of Internal Reliability,Measurement Invariance,and Correlates Across Gender

In this study, we examined estimates of internal consistency reliability, measurement invariance, and differential correlates of the Multidimensional Scale of Perceived Social Support (MSPSS; Zimet, Dahlem, Zimet, & Farley, 1988) in samples of undergraduate men (n = 270) and women (n = 340). The MSPSS is designed to assess 3 sources of perceived social support: family, friends, and significant others. The participants ranged in age from 18 to 24 years (M _age = 19.60, SD = 1.4 years). First, composite scale reliability and coefficient omega methods provided adequate estimates of internal consistency reliability for the original MSPSS total and subscale scores. Second, results of multiple-groups invariance confirmatory factor analysis provided support for configural and metric invariance. Partial measurement invariance was attained for scalar and strict measurement invariance across men and women. Additionally, given the high correlations among the first-order factors, we conducted multiple-groups bifactor item response theory (bifactor-IRT) analysis to evaluate further the performances of the individual MSPSS items across gender. Support for the bifactor model was strong. Third, we conducted a series of simultaneous regression analyses to identify potential correlates of the social support construct for women and men.     

The Effect of Component Meaningfulness on Global-Local Processing in Children and Adults

Global precedence (GP) occurs when individuals exhibit the tendency to notice global, or holistic, information before they notice local, or component, parts of a visual stimulus. Factors such as meaningfulness of components are held constant when measuring GP; however, varying such factors informs us about the underlying mechanisms of GP. In addition, investigating these effects developmentally has increased the understanding of global-local processing. This experiment examines the effect of meaningfulness (letters vs. nonletters) on adults' (n = 24) and 5-year-old children's (n = 23) GP. Adults and children were more accurate if there was one nonletter component, and children were more accurate when the target was located at the local level. However, adults and children were faster if both levels were letters. The developmental path of low-level sensory factors may differ from that of high-level cognitive factors in visual processing, and a general mechanism may account for this.     

Trait Resilience Fosters Adaptive Coping When Control Opportunities are High: Implications for the Motivating Potential of Active Work

Purpose

We examine the interaction between trait resilience and control in predicting coping and performance. Drawing on a person–environment fit perspective, we hypothesized resilient individuals would cope and perform better in demanding work situations when control was high. In contrast, those low in resilience would cope and perform better when control was low. Recognizing the relationship between trait resilience and performance also could be indirect, adaptive coping was examined as a mediating mechanism through which high control enables resilient individuals to demonstrate better performance.

Methodology

In Study 1 (N = 78) and Study 2 (N = 94), participants completed a demanding inbox task in which trait resilience was measured and high and low control was manipulated. Study 3 involved surveying 368 employees on their trait resilience, control, and demand at work (at Time 1), and coping and performance 1 month later at Time 2.

Findings

For more resilient individuals, high control facilitated problem-focused coping (Study 1, 2, and 3), which was indirectly associated with higher subjective performance (Study 1), mastery (Study 2), adaptive, and proficient performance (Study 3). For more resilient individuals, high control also facilitated positive reappraisal (Study 2 and 3), which was indirectly associated with higher adaptive and proficient performance (Study 3).

Implications

Individuals higher in resilience benefit from high control because it enables adaptive coping.

Originality/value

This research makes two contributions: (1) an experimental investigation into the interaction of trait resilience and control, and (2) investigation of coping as the mechanism explaining better performance.

     

Predicting Suicidal Tendencies Among High Risk Youth With the General Theory of Crime

This study examines whether suicidal tendencies among a group of juveniles who have come to the attention of Child Protective Services can be predicted by self-control theory. Using data from the National Survey of Child and Adolescent Well-Being, we find that self-control predicts suicidal tendencies. In addition, the effect of self-control remains significant even when controlling for the juveniles’ depression and previously reported suicidal thoughts and behaviors. This study lends further support to the claim that self-control serves as a general explanation for a wide range of problematic outcomes. In addition, these findings provide caseworkers with another tool for assessing the risk of suicide among high risk youth.     

Relational Spirituality and Forgiveness of Offenses Committed by Religious Leaders

In the present article, we extend a model of relational spirituality and forgiveness to the context of major offenses by clergy. In Study 1, undergraduate students (N = 208) described a major offense that they had experienced by a religious leader and then completed several questionnaires in relation to the offense and the religious leader. Appraisals of relational spirituality were significantly associated with forgiveness, after controlling for known predictors of forgiveness (i.e., hurtfulness, time since the offense, and commitment to God or another source of spirituality). In Study 2, we replicated and extended the findings from Study 1 using an independent sample of undergraduates (N = 365). In a series of structural equation models, we found that relational engagement of God (or another source of spirituality) partially mediated the relationship between anger toward God (or another source of spirituality) and unforgiving motivations. We conclude by discussing implications for future research.
