Individual Differences in Risky Decision Making: A Meta‐analysis of Sensation Seeking and Impulsivity with the Balloon Analogue Risk Task

To represent the state‐of‐the‐art in an effort to understand the relation between personality and risk taking, we selected a popular decision task with characteristics that parallel risk taking in the real world and two personality traits commonly believed to influence risk taking. A meta‐analysis is presented based on 22 studies of the Balloon Analogue Risk Task from which correlations with sensation seeking and impulsivity assessments could be obtained. Results calculated on a total of 2120 participants showed that effect size for the relation of sensation seeking with risk taking was in the small–moderate range ( = .14), whereas the effect size for impulsivity was just around the small effect size threshold ( = .10). Although we considered participants' demographics as moderators, we found only significantly larger effect sizes for the older adolescents and young adults compared with other ages. The findings of the present review supported the view that inconsistencies in personality–risk research were mostly due to random fluctuations of specific effect sizes, rather than to lack of theoretical ties or to measurement unreliability. It is also concluded that studies aimed at relating individual differences in personality to performance in experimental decision tasks need an appropriate sample size to achieve the power to produce significant results.

Ownership Status and the Representation of Assets of Uncertain Value: The Balloon Endowment Risk Task (BERT)

Owners tend to overvalue possessions relative to non‐owners: a phenomenon known as the endowment effect. In three experiments, using markets for goods of uncertain value, we investigated whether this can be partly attributed to misperceiving an asset's profitability or to uncertainty about a good's utility. To test our hypotheses, we devised the Balloon Endowment Risk Task, in which participants can sell or buy their right to participate in the Balloon Analogue Risk Task. Once purchased/retained, a virtual balloon is pumped to accrue money, which is lost if the balloon bursts. Participants first learn about the risky asset (balloon) by observing others playing the Balloon Analogue Risk Task before they enter the market. In Experiment 1, we replicated the endowment effect; yet, owners and non‐owners predicted pumping the same number of times and subsequently did so when given that opportunity. In Experiments 2 and 3, the level of uncertainty about the balloon's profitability was manipulated by modifying the number of bursts that participants viewed in the initial learning stage. When more diagnostic information was provided, making the average burst point easier to estimate and reducing value uncertainty and increasing confidence in valuation, the endowment effect diminished although mean estimates of the average burst point did not differ between owners and non‐owners. Thus, endowment effects were partly attributable to value uncertainty but could not be explained by owners and non‐owners having divergent perceptions of the asset's payoff distribution.

Effects of adaptive cruise control and highly automated driving on workload and situation awareness: A review of the empirical evidence

Adaptive cruise control (ACC), a driver assistance system that controls longitudinal motion, has been introduced in consumer cars in 1995. A next milestone is highly automated driving (HAD), a system that automates both longitudinal and lateral motion. We investigated the effects of ACC and HAD on drivers’ workload and situation awareness through a meta-analysis and narrative review of simulator and on-road studies. Based on a total of 32 studies, the unweighted mean self-reported workload was 43.5% for manual driving, 38.6% for ACC driving, and 22.7% for HAD (0% = minimum, 100 = maximum on the NASA Task Load Index or Rating Scale Mental Effort). Based on 12 studies, the number of tasks completed on an in-vehicle display relative to manual driving (100%) was 112% for ACC and 261% for HAD. Drivers of a highly automated car, and to a lesser extent ACC drivers, are likely to pick up tasks that are unrelated to driving. Both ACC and HAD can result in improved situation awareness compared to manual driving if drivers are motivated or instructed to detect objects in the environment. However, if drivers are engaged in non-driving tasks, situation awareness deteriorates for ACC and HAD compared to manual driving. The results of this review are consistent with the hypothesis that, from a Human Factors perspective, HAD is markedly different from ACC driving, because the driver of a highly automated car has the possibility, for better or worse, to divert attention to secondary tasks, whereas an ACC driver still has to attend to the roadway.     

Iowa Gambling Task performance and executive function predict low-income urban preadolescents’ risky behaviors

This study examines preadolescents’ reports of risk-taking as predicted by two different, but related inhibitory control systems involving sensitivity to reward and loss on the one hand, and higher order processing in the context of cognitive conflict, known as executive functioning (EF), on the other. Importantly, this study examines these processes with a sample of inner-city, low-income preadolescents and as such examines the ways in which these processes may be related to risky behaviors as a function of children’s levels of both concurrent and chronic exposure to household poverty. As part of a larger longitudinal study, 382 children (ages 9–11) provided a self-report of risky behaviors and participated in the Iowa Gambling Task, assessing bias for infrequent loss (preference for infrequent, high magnitude versus frequent, low magnitude loss) and the Hearts and Flowers task assessing executive functioning. Results demonstrated that a higher bias for infrequent loss was associated with higher risky behaviors for children who demonstrated lower EF. Furthermore, bias for infrequent loss was most strongly associated with higher risk-taking for children facing highest levels of poverty. Implications for early identification and prevention of risk-taking in inner-city preadolescents are discussed.     

Work engagement during life-span: The role of interaction outside the organization and task significance

Growing proportion of older employees in the workforce has pushed scholars and managers to examine the changes of individual work-related attitudes and behavior during the life-span and accordingly reconsider work design to sustain the engagement of aging workforces. This study contributes to ambiguous previous findings by investigating age–work engagement linkage and moderating effects of such job characteristics as employees' perceived task significance and interaction outside organization. Survey of bank employees revealed an overall positive linear effect of age on work engagement; task significance was further positively related to work engagement. Although the direct impact of interaction outside the organization to work engagement was not found, the interaction outside the organization moderated the relationship between age and work engagement: older employees with more external interactions reported higher engagement levels than older employees with fewer interactions. Work engagement was highest for older employees who experienced more interaction outside the organization, or perceived their work as significant or both. There was no positive effect of age on work engagement for employees with both lower levels of interaction outside organization and lower task significance.     

How providing more or less time to solve a cognitive task interferes with upright stance control; a posturographic analysis on healthy young adults

Contrasted postural effects have been reported in dual-task protocols associating balance control and cognitive task that could be explained by the nature and the relative difficulty of the cognitive task and the biomechanical significance of the force platform data. To better assess their respective role, eleven healthy young adults were required to stand upright quietly on a force platform while concomitantly solving mental-calculation or mental-navigation cognitive tasks. Various levels of difficulty were applied by adjusting the velocity rate at which the instructions were provided to the subject according to his/her maximal capacities measured beforehand. A condition without any concomitant cognitive task was added to constitute a baseline behavior. Two basic components, the horizontal center-of-gravity movements and the horizontal difference between center-of-gravity and center-of-pressures were computed from the complex center-of-pressure recorded movements. It was hypothesized that increasing the delay should infer less interaction between postural control and task solution. The results indicate that both mental-calculation and mental-navigation tasks induce reduced amplitudes for the center-of-pressure minus center-of-gravity movements, only along the mediolateral axis, whereas center-of-gravity movements were not affected, suggesting that different circuits are involved in the central nervous system to control these two movements. Moreover, increasing the delays task does not infer any effect for both movements. Since center-of-pressure minus center-of-gravity expresses the horizontal acceleration communicated to the center-of-gravity, one may assume that the control of the latter should be facilitated in dual-tasks conditions, inferring reduced center-of-gravity movements, which is not seen in our results. This lack of effect should be thus interpreted as a modification in the control of these center-of-gravity movements. Taken together, these results emphasized how undisturbed upright stance control can be impacted by mental tasks requiring attention, whatever their nature (calculation or navigation) and their relative difficulty. Depending on the provided instructions, i.e. focusing our attention on body movements or on the opposite diverting this attention toward other objectives, the evaluation of upright stance control capacities might be drastically altered.     

True self-alienation positively predicts reports of mindwandering

Two studies assessed the relationship between feelings of uncertainty about who one truly is (i.e., true self-alienation) and self-reported task-unrelated thoughts (i.e., mindwandering) during performance tasks. Because true self-alienation is conceptualized as the subjective disconnect between conscious awareness and actual experience, we hypothesized that greater feelings of true self-alienation would positively relate to subjective reports of mindwandering. Two convergent studies supported this hypothesis. Moreover, this relationship could not consistently be accounted for by the independent influence of other aspects of authenticity, negative mood, mindfulness, or broad personality dimensions. These findings suggest that individual differences in true self-alienation are reliably associated with subjective reports of mindwandering. The implications of these findings for the true self-alienation construct, the ways that personality relates to mindwandering, and future research directions focused on curtailing mindwandering and improving performance and achievement are discussed.     

Examining the relationship between athletes' achievement goal orientation and ability to employ imagery

ObjectiveImagery ability may be cognitively regulated by motivational states, thus it is important to determine the relationship between goal orientations and imagery ability. Design/Method: Participants were 272 male and female athletes, representing nine sports. Goal orientations and cognitive and motivational imagery abilities were assessed via questionnaires. Task and ego goal orientations were examined via a two-step cluster analysis procedure, resulting in the identification of four goal orientation clusters. Separate multivariate analyses were conducted to assess differences in cognitive imagery ability and motivational imagery ability for the clusters, with gender and sport type entered as covariates. Results: For cognitive imagery ability, gender had a significant effect for athletes with low task/low ego orientation; female athletes rated their internal imagery perspective as clearer and more vivid. Regarding motivational imagery ability, when sport type was controlled for, cluster membership demonstrated a significant multivariate effect. Goal orientations have a relationship with motivational imagery ability but this same relationship was not evident with cognitive imagery ability. Athletes with high task/high ego or high task/low ego goal orientations scored significantly higher on their ability to feel emotions and their ease of generating motivational general-mastery images compared to athletes with low task/high ego or low task/low ego orientations. No differences between goal orientation clusters were found for motivational general-arousal imagery ability. Conclusion: Athletes who have a high task orientation are very motivated and have an easy time forming mastery images and a high ability to experience the emotion of these images.     

Imagery and self-efficacy in the injury context

ObjectivesTo develop and test the factorial validity of an adapted version of the Athletic Injury Imagery Questionnaire (AIIQ-2: Sordoni, Hall, & Forwell, 2002). To explore the effect of an imagery intervention on self-efficacy in the sport injury context.DesignStudy 1, cross-sectional; Study 2, multiple-base line.MethodIn Study 1 the AIIQ-2 was adapted to include a pain management subscale. This adapted imagery questionnaire (AIIQ-3) was then administered to 291 injured athletes (M age = 28.64 years, SD = 14.30). In Study 2 using a multiple-baseline single subject design, the effects of an imagery intervention on self-efficacy prior to physiotherapy treatment of five athletes with a Type B malleolar fracture (M age = 49.50 years, SD = 16.56) was examined. A follow-up post-experimental interview explored participants' perceptions of the intervention.ResultsStudy 1, confirmatory factor analysis revealed evidence for the factorial validity of the AIIQ-3. Study 2, results from the multiple-base line design demonstrated that for two out of the five participants there were observable and statistically meaningful increases in task efficacy, with the same result in three out of five participants for coping efficacy. The post-interview results revealed that all intervention participants perceived the intervention to be beneficial and effective beyond the general information provided.ConclusionsThe results are discussed in terms of overcoming an inherent weakness in previous injury-related imagery research and the applied implications for the time-course of rehabilitation.     

Lady Liberty and Godfather Death as candidates for linguistic relativity? Scrutinizing the gender congruency effect on personified allegories with explicit and implicit measures

Linguistic relativity—the idea that language affects thought by way of its grammatical categorizations—has been controversially debated for decades. One of the contested cases is the grammatical gender of nouns, which is claimed to affect how their referents are conceptualized (i.e., as rather female or male in congruence with the grammatical gender of the noun), especially when used allegorically. But is this association strong enough to be detected in implicit measures, and, if so, can we disentangle effects of grammatical gender and allegorical association? Three experiments with native speakers of German tackled these questions. They revealed a gender congruency effect on allegorically used nouns, but this effect was stronger with an explicit measure (assignment of biological sex) than with an implicit measure (Extrinsic Affective Simon Task) and disappeared in the implicit measure when grammatical gender and allegorical associations were set into contrast. Taken together, these findings indicate that the observed congruency effect was driven by the association of nouns with personifications rather than by their grammatical gender. In conclusion, we also discuss implications of these findings for linguistic relativity.
