Patterns of Responding on a Balloon Analogue Task Reveal Individual Differences in Overall Risk-Taking: Choice Between Guaranteed and Uncertain Cash

ABSTRACT. We explored the utility of analyzing within- and between-balloon response patterns on a balloon analogue task (BAT) in relation to overall risk scores, and to a choice between a small guaranteed cash reward and an uncertain reward of the same expected value. Young adults (n = 61) played a BAT, and then were offered a choice between $5 in cash and betting to win $0 to $15. Between groups, pumping was differentially influenced by explosions and by the number of successive unexploded balloons, with risk takers responding increasingly on successive balloons after an explosion. Within-balloons, risk takers showed a characteristic pattern of constant high rate, while non-risk takers showed a characteristic variable lower rate. Overall, results show that the higher number of pumps and explosions that characterize risk takers at a molar level, result from particular forms of adaptation to the positive and negative outcomes of choices seen at a molecular level.

Leveraged Resources and Systems Changes in Community Collaboration

Most models of community collaboration emphasize the ability of diverse partners to come together to enact systematic changes that improve the health of individuals and communities. The ability of these groups to leverage resources is thought to be an important marker of successful collaboration and eventual improvements in community health. However, there is a paucity of research addressing linkages between systems change activities and leveraged resources. This study used a sample of collaboratives (N = 157) that received technical assistance and funding through the Georgia Family Connection Partnership (GaFCP) between 2006 and 2007. Data were collected from collaborative report of activities and funding, member ratings of collaborative functioning, and characteristics of the communities served by the collaboratives drawn from US Census data. Cross-lagged regression models tested longitudinal associations between systems change activities and leveraged dollars. The results indicated that systems change activities predict increased leveraging of resources from state/federal and private partners. However, there was no evidence that systems changes were linked with leveraging resources from local groups and agencies. These findings have important implications for providing technical assistance and training to health partnerships. Furthermore, future research should consider the relative strength of different systems change activities in relation to the ability of coalitions to leverage resources.     

What Does Children's Spatial Language Reveal About Spatial Concepts? Evidence From the Use of Containment Expressions

Children's overextensions of spatial language are often taken to reveal spatial biases. However, it is unclear whether extension patterns should be attributed to children's overly general spatial concepts or to a narrower notion of conceptual similarity allowing metaphor‐like extensions. We describe a previously unnoticed extension of spatial expressions and use a novel method to determine its origins. English‐ and Greek‐speaking 4‐ and 5‐year‐olds used containment expressions (e.g., English into, Greek mesa) for events where an object moved into another object but extended such expressions to events where the object moved behind or under another object. The pattern emerged in adult speakers of both languages and also in speakers of 10 additional languages. We conclude that learners do not have an overly general concept of Containment. Nevertheless, children (and adults) perceive similarities across Containment and other types of spatial scenes, even when these similarities are obscured by the conventional forms of the language.     

Measurement invariance of the Satisfaction With Life Scale (SWLS) by gender and age in Angola

Subjective well-being is a research arena that has grown almost exponentially: over the last 20 years, the number of publications on subjective well-being has increased approximately 16-fold (Diener, 2009). The cognitive aspect of subjective well-being or life satisfaction is referred to a conscious cognitive judgment of life (Diener, Emmons, Larsen, & Griffin 1985), in which person’s quality of life is globally assessed (Shin & Johnson, 1978). The Satisfaction With Life Scale (SWLS, Diener et al., 1985) is the most widely used instrument for its measurement. A reliable, valid and invariant measurement is critical for meaningful comparisons. The aim of this study is to examine the configural, metric and scalar invariance across age in the Portuguese version of the SWLS with a sample of 5630 Angolans. A standard measurement invariance procedure has been applied both across gender and age. Results shown that scalar invariance of the SWLS held across gender and age. This strong invariance allowed for meaningful latent mean comparisons. There were latent mean differences due to gender and age, but while gender differences were modest, the age differences were larger. Results are discussed in their relation with existing literature.     

Do Bettors Correctly Perceive Odds? Three Studies of How Bettors Interpret Betting Odds as Probabilistic Information

This paper reports on three studies investigating how accurately bettors (=people who regularly bet on sports events) interpret the probabilistic information implied by betting odds. All studies were based on data collected by web surveys prompting a total of 186 experienced bettors to convert sets of representative odds into frequency judgments. Bayesian statistical methods were used to analyze the data. From the results, the following conclusions were made: (i) On the whole, the bettors produced well‐calibrated judgments, indicating that they have realistic perceptions of odds. (ii) Bettors were unable to consciously adjust judgments for different margins. (iii) Although their interval judgments often covered the estimates implied by the odds, the bettors tended to overestimate the variation of expected profitable bets between months. The results are consistent with prior research showing that people tend to make accurate probability judgments when faced with tasks characterized by constant and clear feedback.

The TRAMS: The Team-Referent Attributions Measure in Sport

ObjectivesTo provide initial evidence for the construct, concurrent, and predictive validity of the Team-Referent Attributions Measure in Sport (the TRAMS).DesignCross-sectional in Studies 1 and 2, and multiple time points in Study 3.MethodStudy 1 required participants (N = 500) to complete the TRAMS for their “least successful” and “most successful” performances in the preceding three months. In Study 2, after performance, participants (N = 515) completed the TRAMS and the Causal Dimension Scale for Teams (CDS-T; Greenlees et al., 2005). Study 3 required participants (N = 165) to complete a measure of pre-competition collective-efficacy prior to performance (Day 1, Time 1), the TRAMS following performance (Day 1, Time 2), and a measure of subsequent collective-efficacy prior to subsequent performance (Day 7–9, Time 3).ResultsStudy 1 supported the factor structure of the TRAMS across least successful and most successful conditions. Study 2 provided further support for the factor structure of the TRAMS, together with evidence of concurrent validity with subscales of the CDS-T. Study 3 revealed, following team defeat, interactions between controllability and generalisability dimensions: Controllability had a significant effect upon subsequent collective-efficacy when causes of team defeat were also perceived to generalise across situations and/or across teams. Following team victory, stable attributions were positively associated with subsequent collective-efficacy.ConclusionsThis article provides initial evidence for the validity of the TRAMS and demonstrates for team-referent attributions the theoretical advantages of examining a broader conceptualisation of generalisability attributions and interactive effects of attributions.     

Does habit strength moderate the intention–behaviour relationship in the Theory of Planned Behaviour? The case of fruit consumption

The present study examined if habit strength moderated the influence of intention on fruit consumption in a Dutch adult sample (N?=?521, 46.3% males, mean age?=?34.50, SD?=?10.87), using the theoretical relations of the Theory of Planned Behaviour (TPB). TPB variables and habit strength were assessed at baseline. Fruit consumption was assessed with a validated questionnaire five weeks later. Three groups were created: low habit strength (n?=?180), medium habit strength (n?=?185) and high habit strength (n?=?156). Confirmatory factor analyses and multi-group path analyses were performed using AMOS 4.0. A good fit was obtained for the overall measurement model and the structural models. Multi-group path analyses showed that intention was a significant predictor of fruit consumption in the low habit (β?=?0.36, p?<?0.001) and medium habit group (β?=?0.30, p?<?0.001), but a non-significant predictor in the high habit group (β?=?0.05, p?=?0.596). Implications for information-based and motivation-based interventions are discussed.     

Changes in Catastrophizing and Depressed Mood During and After Early Cognitive Behaviorally Oriented Interventions for Pain

Catastrophizing and depressed mood are risk factors for poor outcome in treatments for pain and appear to act as mediators for favorable outcome. However, little is known about how catastrophizing and depressed mood co-occur within individuals and how these patterns change during treatment, which is the focus of the current study. The study uses data from a randomized controlled trial about early cognitive behaviorally oriented interventions for patients with nonspecific spinal pain (N = 84). Cluster analyses were used to extract subgroups of individuals with similar scoring patterns on catastrophizing and depressed mood at pretreatment, mid-treatment, posttreatment, and at 6 months' follow-up. To track individual progress, the clusters were linked over time. The analyses revealed four clusters: “low depression and catastrophizing”, “high depression and catastrophizing”, “high depression”, and “high catastrophizing”. There was little individual transition from one scoring pattern to another across time, not at least for those scoring high on both depressed mood and catastrophizing. Moreover, high stability within this cluster was related to low levels of psychological flexibility at baseline. It is concluded that catastrophizing and depressed mood at the start of treatment were likely to remain high despite a cognitive behavioral intervention and that a lack of psychological flexibility may have a role.     

A Latent Variable Framework for Power Estimation Within Intervention Contexts

This paper presents a latent growth SEM approach for the estimation of treatment effects, and power to detect such effects, within a true experimental design setting in which subjects are randomly assigned to treatment and control conditions. Power estimation is a critical component of intervention experiment design and the testing of their results. Although researchers have become increasingly sophisticated in applying tests for statistical significance in intervention contexts, few are aware of the power of these tests. The issues raised in this paper are not new; however, reminding researchers to consider these points is important. Exactly how the researcher handles these issues will depend on the questions asked and the resources available, as well as other considerations. Discussion underscores the relationship between the reliability of a study's measures and concomitant increases in power obtained within the SEM framework.
