Does activating justice help or hurt in promoting forgiveness?

Do justice values promote or obstruct forgiveness? This question has received virtually no empirical attention, even though past theorizing suggest two different answers. The literature on forgiveness suggests that justice constitutes a barrier to forgiveness, suggesting that the activation of justice values should decrease the probability of forgiveness. Conversely, the literature on justice and human values indicates that justice and forgiveness are positively associated, suggesting that the activation of justice should enhance the probability of forgiveness. Consistent with the latter line of reasoning, three studies, using complementary priming methods, provide converging evidence for the prediction that the activation of justice promotes (rather than obstructs) forgiveness. Implications for extant theory regarding forgiveness and justice are discussed.     

The pantomime of persuasion: Fit between nonverbal communication and influence strategies

How can we be more successful in persuading others and increase the odds of behavioral compliance? We argue that when a verbal influence strategy is embedded in a nonverbal style that fits its orientation, this boosts the strategy's effectiveness, whereas a misfit attenuates its impact. In field-experiment 1, agents tried to persuade participants in buying a candybox by using an approach-oriented strategy (Door-In-The-Face, DITF). An eager nonverbal style increased the impact of the DITF, whereas vigilant nonverbal cues rendered it ineffective. Conversely, field-experiment 2 showed that an avoidance-oriented strategy (Disrupt-Then-Reframe) benefited from being presented in a vigilant, rather than an eager nonverbal style, which similarly attenuated its impact. Hence, eager nonverbal cues promote the effectiveness of approach-oriented influence strategies whereas vigilant cues do the opposite and increase the impact of avoidance-oriented influence strategies.     

Model checking propositional dynamic logic with all extras

This paper presents a model checking algorithm for Propositional Dynamic Logic (PDL) with looping, repeat, test, intersection, converse, program complementation as well as context-free programs. The algorithm shows that the model checking problem for PDL remains PTIME-complete in the presence of all these operators, in contrast to the high increase in complexity that they cause for the satisfiability problem.     

Okasha on Inductive Scepticism

In a recent paper replying to the inductive sceptic, Samir Okasha says that the Humean argument for inductive scepticism depends on mistakenly construing inductive reasoning as based on a principle of the uniformity of nature. I dispute Okasha's argument that we are entitled to the background beliefs on which (he says) inductive reasoning depends. Furthermore, I argue that the sorts of theoretically impoverished contexts to which a uniformity-of-nature principle has traditionally been restricted are exactly the contexts relevant to the inductive sceptic's argument, and ( pace Okasha) are not at all remote from actual scientific practice. I discuss several scientific examples involving such contexts.     

Interapy: treatment of post-traumatic stress via the internet

This paper describes the theoretical background and procedures (including psycho-education, screening, treatment protocol and outcome measurement) involved in a protocol-driven internet treatment of post-traumatic stress and grief in a group of people who have suffered from mild to relatively severe trauma. The paper examines the results of 3 outcome and process studies, which were carried out initially in a student population and subsequently in the general population of highly traumatized people. In the latter study, participants in the experimental condition (n = 69) improved significantly more than participants in the waiting list control condition (n = 32), with respect to trauma-related symptoms and general psychopathology. The effect sizes were large. More than 50% of the participants treated showed reliable change and clinically significant improvement after treatment for avoidance and depression. Treatment proved most beneficial for participants who had suffered from intentional trauma and those who had not previously discussed the traumatic events with significant others. Content analysis of the publications indicates a remarkable increase in cognitive coping during treatment. The possibilities for future research into internet-driven treatment of post-traumatic stress symptomatology are discussed, including the proposal to study the effects of sending a final written letter to a significant other person.     

Parents' personality and infants' temperament as contributors to their emerging relationship

The authors examined the contributions of infant's temperament and parent's personality to their relationship. In Study 1, 102 infants, mothers, and fathers were studied when infants were 7 months; in Study 2, 112 infants and mothers were followed from 9 to 45 months. Infants' temperament (joy, fear, anger, and attention) was observed in standard temperament paradigms. Parents' personality measures encompassed the Big Five traits and Empathy in Study 1 and Mistrust, Manipulativeness, Aggression, Dependency, Entitlement, and Workaholism in Study 2. Parent-child relationship (shared positive affect and parental responsiveness in Studies 1 and 2 and parental tracking of the infant in Study 1) was observed in naturalistic contexts. In Study 1, mothers' Neuroticism, Empathy, and Conscientiousness and fathers' Agreeableness, Openness, and Extraversion related to the relationship with the infants. All measures of infant temperament also related to the emerging relationship. In Study 2, maternal Mistrust, Manipulativeness, Dependency, and Workaholism predicted the relationship with the child.     

How to cope with "noise" in social dilemmas: the benefits of communication

Interactions in social life may be seriously affected by negative noise, whereby actual or perceived behavior is less cooperative than was intended (e.g., arriving late due to an unforeseen traffic jam). The present research examines whether negative noise exerts detrimental effects on impressions and cooperation and whether such effects could be reduced by communication. Consistent with hypotheses, Study 1 revealed that negative noise exerts detrimental effects on both impressions of partners' benign intent and cooperation and that these detrimental effects could be effectively reduced by communication about noise. Study 2 replicated both findings but only for individuals with low trust. Mediation analysis revealed that impressions of benign intent and prosocial interaction goals underlie the positive effects of communication on cooperation.
