The hierarchical order of processes underlying the direction illusion and the direction aftereffect

Motion perception involves the processing of velocity signals through several hierarchical stages of the visual cortex. To better understand this process, a number of studies have sought to localise the neural substrates of two misperceptions of motion direction, the direction illusion (DI) and the direction aftereffect (DAE). These studies have produced contradictory evidence as to the hierarchical order of the processing stages from which the respective phenomena arise. We have used a simple stimulus configuration to further investigate the sequential order of processes giving rise to the DI and DAE. To this end, we measured the two phenomena invoked in combination, and also manually parsed this combined effect into its two constituents by measuring the two phenomena individually in both possible sequential orders. Comparing the predictions made from each order to the outcome from the combined effect allowed us to test the tenability of two models: the DAE-first model and the DI-first model. Our results indicate that DAE-invoking activity does not occur earlier in the motion processing hierarchy than DI-invoking activity. Although the DI-first model is not inconsistent with our data, the possible involvement of non-sequential processing may be better able to reconcile these results with those of previous studies.     

“I have paid my dues”: When physical pain reduces interpersonal justice motivations

In this study we show that experiencing physical pain interacts with justice related cognition and serves to reduce justice-restoring behavior in the context of interpersonal moral transgressions. This is because concepts of punishment and justice are embodied within the experience of pain, allowing for a sense of atonement from one’s wrongdoings. Two thirds of the participants were induced to feel that their performance in a two player game was unfair. Half of those participants were then asked to engage in a physically painful task, and were afterwards less likely to make amends for past poor performance compared to players who completed a similar, but non-painful task. This effect was only evident for participants who are particularly sensitive to personal injustices and therefore sensitive to the justice restoring qualities of pain.     

Remedial responsibilities beyond nations

David Miller's theory of nationalism and national responsibility offers the leading alternative ‘anticosmopolitan’ theory of global justice. His theory claims that ‘nations’ may be held responsible for the benefits and harms resulting from their collective decisions. Nations may be held remedially responsible to help nations in need even where the former lack causal or moral responsibility, for example. This article critically examines Miller's position that remedial responsibilities – the responsibilities of nations to remedy others in need – can and should only be satisfied by nations. I argue that the characteristics that define and justify a particular understanding of nationalism extend to further constructions of identity, such as religious affiliation and other connections. The problem with Miller's position is that it is overly narrow by focusing solely on our national identities as the characteristic most relevant for determining remedial responsibilities. It is possible and desirable to widen our focus, enriching our understanding of global justice and remedial responsibility. Moreover, this wider perspective is an extension, and not a break from, Miller's position. Our shared identities should have significance for considerations of global justice and they can help us to develop a more robust view of anticosmopolitanism.     

Virtual Reality and Cognitive-Behavioral Therapy for Driving Anxiety and Aggression in Veterans: A Pilot Study

Within the U.S. military, motor vehicle accidents (MVAs) are the leading cause of preventable morbidity and mortality. Prior combat exposure and anxiety symptoms are associated with risky and aggressive driving, which is responsible for over half of MVA fatalities. Therefore, interventions are needed to reduce driving anxiety and aggression in veterans in order to mitigate the public health impact of MVAs. Virtual reality exposure therapy (VRET) offers safe, controlled exposure to distressing stimuli. The current study piloted a novel virtual reality and cognitive behavioral intervention (VRET + CBT) for veterans that integrated both anxiety and anger management components. Virtual reality driving scenarios were delivered in a driving simulator and tailored for the military population. Six previously deployed veterans completed eight intervention sessions, as well as pre/post, one month follow-up and six to nine month follow-up assessments. Repeated measures ANOVAs demonstrated significant decline and large effect sizes for PTSD symptoms, driving phobia, hyperarousal in driving situations, anxiety/anger-related thoughts and behaviors, and risky driving. Hyperarousal in driving situations declined by 69%, aggressive driving declined by 29%, and risky driving declined by 21%. Treatment gains were maintained at follow-up. Recruitment, retention, immersion, simulator sickness scores, and qualitative feedback demonstrated feasibility of the intervention. Implications for future research and adaptation are discussed.     

Keeping It Going: Evidence of Long-Term Improvements After Implementation of the 1-2-3 Magic Parenting Program

This study builds upon a pilot evaluation of the 1-2-3 Magic Program (Bailey, van der Zwan, Phelan, &; Brooks, 2012 Bailey, E. L., van der Zwan, R., Phelan, T. W., &; Brooks, A. (2012). The 1–2-3 Magic Program: Implementation outcomes of an Australian pilot evaluation with school-aged children. Child &; Family Behavior Therapy, 34(1), 53–69. doi:10.1080/07317107.2012.654455[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]), by investigating its long-term efficacy as a brief parenting intervention for families with a school-aged child. Twelve Australian families participated in a randomized controlled trial, assigned either to a wait-listed control group or to one that received immediate training. Consistent with the pilot evaluation, only families who had received training reported significant improvement in child and parenting behavior at an 8-week follow-up assessment. These improvements were maintained for 12-month posttraining, supporting the long-term efficacy of the 1-2-3 Magic Program for Australian families.
