Translating cognitive neuroscience to the driver's operational environment: a neuroergonomic approach

Neuroergonomics provides a multidisciplinary translational approach that merges elements of neuroscience, human factors, cognitive psychology, and ergonomics to study brain structure and function in everyday environments. Driving safety, particularly that of older drivers with cognitive impairments, is a fruitful application domain for neuroergonomics. Driving makes demands on multiple cognitive processes that are often studied in isolation and so presents a useful challenge in generalizing findings from controlled laboratory tasks to predict safety outcomes. Neurology and the cognitive sciences help explain the mechanisms of cognitive breakdowns that undermine driving safety. Ergonomics complements this explanation with the tools for systematically exploring the various layers of complexity that define the activity of driving. A variety of tools, such as part task simulators, driving simulators, and instrumented vehicles, provide a window into cognition in the natural settings needed to assess the generalizability of laboratory findings and can provide an array of potential interventions to increase driving safety.     

Watching films with magical content facilitates creativity in children

Two experiments examined the possible link between magical thinking and creativity in preschool children. In Exp. 1, 4- and 6-yr.-old children were shown a film with either a magical or nonmagical theme. Results indicated that the mean scores of children shown the magical film was significantly higher than that of children watching the nonmagical film on the majority of subsequent creativity tests for both age groups. This trend was also found for 6-yr.-olds' drawings of impossible items. In Exp. 2, Exp. 1 was replicated successfully with 6- and 8-yr.-old children. Exposing children to a film with a magical theme did not affect their beliefs about magic. The results were interpreted to accentuate the role of magical thinking in children's cognitive development. Classroom implications of the results were also discussed.     

Adaptive and maladaptive personality traits as predictors of violent and nonviolent offending behavior in men and women

The aim of this study was to assess both violent and nonviolent offending behavior in a single, mixed‐sex population. The rationale for this is that the two types of offending are usually researched separately, despite evidence that they overlap. A comprehensive measure of general violence, intimate partner violence (IPV), and nonviolent offending behavior was administered to 116 men and 181 women, together with measures of personality and personality disorder (PD) traits, to investigate whether predictors of violent and nonviolent offending were similar or different for men and women. Men were found to perpetrate higher levels of general violence and nonviolent offenses than women, but women perpetrated significantly more IPV than men. Cluster B PD traits predicted all three offense types for women and also men's general violence and nonviolent offending. Women's general violence and men's non‐violence also had one unique risk factor each, low agreeableness, and low conscientiousness, respectively. The main difference was for IPV, where men's IPV was predicted by cluster A PD traits, indicating that men's and women's risk factors for IPV may be different, although their risk factors for the other offense types were fairly consistent.

Local and global processing in savant artists with autism

We explored the hypothesis that an enhanced local processing style is characteristic of both art and autism spectrum disorder (ASD) by examining local and global processing in savant artists with ASD. Specifically, savant artists were compared against non-talented individuals with ASD or mild/moderate learning difficulties (MLD), as well as artistically talented or nontalented students, on the block-design task and meaningful and abstract versions of the embedded figures test (EFT). Results demonstrated that there were no significant differences between the meaningful and abstract versions of the EFT, in any of the groups. This suggests that the primary process governing performance on this task was perceptual (local), rather than conceptual (global). More interestingly, the savant artists performed above the level of the ASD and MLD groups on the block-design test, but not the EFT. Despite both the block-design task and the EFT measuring local processing abilities, we suggest that this result is due to the block-design task being an active construction task (requiring the conversion of a visual input into a motor output), whereas the EFT is a passive recognition task. Therefore, although an enhanced local processing style is an important aspect of savant artistic talent, motor control also appears to be a necessary skill.     

THE MIDDLE AGES: CHANGE IN WOMEN'S PERSONALITIES AND SOCIAL ROLES

It has been argued that the predominant focus of midlife personality development is generativity; other research has found that social roles influence both its onset and its expression. In this article, we examine women's midlife personality development and its relationship to career and family commitments. Results for a sample of 90 women indicated that commitment to particular social projects in early midlife was associated with different patterns of identity, intimacy, and generativity levels at age 62. In addition, women who added social projects to existing projects during adulthood expressed similar levels of identity, intimacy, and generativity at age 62 as women whose social project commitments had stayed the same. For smaller subsamples of women in the study, longitudinal analyses assessed changes in personality development within middle age as well as the relationship between personality and the maintenance or addition of social projects. These results highlight important variation among women who followed different adult life paths.     

Coherence shifts in probabilistic inference tasks

The fast‐and‐frugal heuristics approach to probabilistic inference assumes that individuals often employ simple heuristics to integrate cue information that commonly function in a non‐reciprocal fashion. Specifically, the subjective validity of a certain cue remains stable during the application of a heuristic and is not changed by the presence or absence of another cue. The parallel constraint satisfaction (PCS) model, in contrast, predicts that information is processed in a reciprocal fashion. Specifically, it assumes that subjective cue validities interactively affect each other and are modified to coherently support the favored choice. Corresponding to the model's simulation, we predicted the direction and the size of such coherence shifts. Cue validities were measured before, after (Experiment 1), and during judgment (Experiments 2 and 3). Coherence shifts were found in environments involving real‐world cue knowledge (weather forecasts) and in a domain for which the application of fast‐and‐frugal heuristics has been demonstrated (city‐size tasks). The results indicate that subjective cue validities are not fixed parameters, but that they are interactively changed to form coherent representations of the task.

Subtly offending feedback

Providing acceptable negative feedback is difficult because it may threaten the receiver's self‐esteem. Studies have established that destructive feedback elicits stronger negative reactions than constructive feedback. However, these destructive conditions were quite strong, implying a clear threat to the self. Because of the importance of protecting one's self‐concept, negative evaluations might be provoked by more subtle cues. Such cues should also be detected by observers. We developed three variants of subtly offending feedback in which mistakes appeared disproportionately serious. In an experimental pilot study, 132 student observers judged the fairness of feedback given to another student. The subtly offending conditions were evaluated as less fair than constructive feedback but as more fair than destructive feedback.     

Mechanisms of Moral Disengagement in the Endorsement of Asylum Seeker Policies in Australia

Moral disengagement is a process whereby the self-regulatory mechanisms that would otherwise sanction unethical conduct can be selectively disabled. The present research proposed that moral disengagement might be adopted in the endorsement of asylum seeker policies in Australia, and in order to test this, a scale was developed and was validated in two studies. Factor analysis demonstrated that a 2-factor, 16-item structure had the best fit, and the construct validity of the scale was supported. Results provide evidence for the use of moral disengagement in the context of asylum seekers as a means of rationalizing conduct that may otherwise be sanctioned.
