What time travelers cannot not do (but are responsible for anyway)

The Principle of Alternative Possibilities is the intuitive idea that someone is morally responsible for an action only if she could have done otherwise. Harry Frankfurt has famously presented putative counterexamples to this intuitive principle. In this paper, I formulate a simple version of the Principle of Alternative Possibilities that invokes a course-grained notion of actions. After warming up with a Frankfurt-Style Counterexample to this principle, I introduce a new kind of counterexample based on the possibility of time travel. At the end of the paper, I formulate a more sophisticated version of the Principle of Alternative Possibilities that invokes a certain fine grained notion of actions. I then explain how this new kind of counterexample can be augmented to show that even the more sophisticated principle is false.     

Evidence for a response preparation bottleneck during dual-task performance: Effect of a startling acoustic stimulus on the psychological refractory period

The present study was designed to investigate the mechanism associated with dual-task interference in a psychological refractory period (PRP) paradigm. We used a simple reaction time paradigm consisting of a vocal response (R1) and key-lift task (R2) with a stimulus onset asynchrony (SOA) between 100 ms and 1500 ms. On selected trials we implemented a startling acoustic stimulus concurrent with the second stimulus to determine if we could involuntarily trigger the second response. Our results indicated that the PRP delay in the second response was present for both control and startle trials at short SOAs, suggesting the second response was not prepared in advance. These results support a response preparation bottleneck and can be explained via a neural activation model of preparation. In addition, we found that the reflexive startle activation was reduced in the dual-task condition for all SOAs, a result we attribute to prepulse inhibition associated with dual-task processing.     

Differentiation and Intimate Partner Violence

ABSTRACT

This study explored the impact of differentiation of self on Intimate Partner Violence (IPV). We sought to determine if an individual's level of differentiation of self in a relationship adds to the variance accounted for in IPV perpetration by known risk factors, i.e., relational satisfaction, marital conflict, romantic jealousy, depression, and anxiety. Results indicated that differentiation of self in a relationship is a predictor for perpetration of physical intimate partner violence even after controlling for other known risk factors.     

Fay Fransella: A Passionate,Productive Mentor

This article describes the author's experience of being mentored by Fay Fransella during a sabbatical leave and their subsequent 30-year collaboration. It characterizes Fransella's perspective on and contributions to personal construct theory in terms of her passionate commitment to the theory as a practical way of understanding human experience, her exceptionally effective collaborative productivity, and her deep curiosity and commitment to life-long learning.     

The Role of Peers in the Linkages Between Harsh Parenting and Mental Health Outcomes Among Adolescents from Families At-Risk

Harsh parenting is associated with adolescent mental health concerns. Peer relationships also importantly influence adolescent mental health outcomes. Although the direct associations between harsh parenting, peer relationships, and adolescent outcomes have been empirically established, less is known about the extent to which peer relationships mediate the associations between harsh parenting and adolescent outcomes. This study tested the links between harsh parenting, peer relationships, and adolescent outcomes among families at-risk for child maltreatment. With a sample of caregivers and adolescents (n = 218), the results of mediation analyses indicated that peer aggression partially mediated the pathway between harsh parenting and externalizing symptoms of both females and males. Additionally, peer rejection partially mediated the links between harsh parenting and internalizing symptoms of both females and males and peer rejection also was a partial mediator of male externalizing symptoms.     

The effects of mindfulness-based treatments for aggression: A critical review

Recently, there has been significant growth in the empirical literature on mindfulness and mindfulness-based treatments (MBTs). The purpose of the current review was to critically examine and critique eleven studies evaluating MBTs for reducing aggressive behaviors. Articles were divided based on design (i.e., group design vs. single subject). This review highlighted evidence supporting the efficacy of the use of mindfulness-based treatments in individuals with aggressive behavior problems. Many of the group studies had weak designs, limiting the validity of the stated results. Results from the single-subject studies were more promising, providing strong support for the use of MBTs in reducing aggression. However, despite recent advances in the use of MBTs with individuals with aggression problems, questions remain unanswered. Finally, suggestions for future research are made to improve and identify means of evaluating the effectiveness of mindfulness-based treatments in an aggressive population.     

Ideology,Fear of Death,and Death Anxiety

Ideological beliefs have long attracted the attention of social psychologists, who have investigated their genesis as well as their influence on a host of social phenomena. Conservatism, from the Motivated Social Cognition framework, stems from epistemic and existential needs of the individual, and notably the fear of death. However, Terror Management Theory proposes a view of conservatism and its contrary, liberalism, as equivalent cultural worldviews, equally fit to fulfill such needs. In the present contribution, results are presented from five studies, which test the contrasting hypotheses derived from these two perspectives. A new perspective is considered that accounts for these and previous findings.
