Roache’s Argument against the Cohabitation View

Rebecca Roache’s recent critique of David Lewis’s “cohabitation” view assumes that a person cannot be properly concerned about something that rules out that she ever exists. In this brief response, I argue against this assumption.     

The effect of psychological distance on perceptual level of construal

Three studies examined the effect of primed psychological distance on level of perceptual construal, using Navon's paradigm of composite letters (global letters that are made of local letters). Relative to a control group, thinking of the more distant future (Study 1), about more distant spatial locations (Study 2), and about more distant social relations (Study 3) facilitated perception of global letters relative to local letters. Proximal times, spatial locations, and social relations had the opposite effect. The results are discussed within the framework of Construal Level Theory of psychological distance ( Liberman & Trope, 2008 ; Trope & Liberman, 2003 ).     

Short- and Long-Term Effects of Video Game Violence on Interpersonal Trust

Two studies investigate the psychological processes underlying short- and long-term effects of video game violence on interpersonal trust. Study 1 demonstrates that interacting with physically aggressive virtual agents decreases players' trust in subsequent interactions. This effect was stronger for players who were dispositionally sensitive to victimization. In Study 2, long-term effects of adolescents' frequent exposure to video game violence on interpersonal trust and victim sensitivity were investigated. Cross-lagged path analyses show that the reported frequency of playing violent video games reduced interpersonal trust over a period of 12 months, particularly among victim-sensitive players. These findings are in line with the sensitivity to mean intentions (SeMI) model, and they suggest that interpersonal mistrust is a relevant long-term outcome of frequent exposure to video game violence.     

Interference and Facilitation in Spoken Word Production: Effects of Morphologically and Semantically Related Context Stimuli on Picture Naming

We report two picture–word interference experiments investigating conceptual and lexical activation, and response selection, in speaking. We varied stimulus onset asynchrony to investigate potential fine-grained activation and competition effects. Morphologically related existing and pseudoword adjectives, as well as associatively related adjectives, served as context stimuli in Experiment 1. In Experiment 2, we focused on semantic interference by using morphologically related and unrelated subordinates of the target concept as context stimuli. Morphologically complex pseudowords were also included as context stimuli. Pseudowords should not interfere, given that they have no lexical or conceptual representation. We consistently obtained facilitation with all morphologically related context stimuli, irrespective of their lexical status. We argue that effects originate at the word-form level, and discuss how our results may help decide among the many explanations of semantic interference in picture naming.     

Internet-based parent management training: a randomized controlled study

ObjectiveThe current study evaluated the efficacy of an Internet-based parent-training program for children with conduct problems. Dose–response ratio and costs for the program were also considered.MethodParents of 104 children (aged 3–12 years) were randomly allocated to either parent training or a waitlist control condition. Diagnostic assessment was conducted at baseline and parent ratings of child externalizing behaviors and parent strategies were completed before and after treatment and at 6-month follow-up.ResultsAt post-treatment assessment, children whose parent(s) had received the intervention showed a greater reduction in conduct problems compared to the waitlist children. Between group intent-to-treat effect sizes (Cohen’s d) on the Eyberg Intensity and Problem scales were .42 and .72, respectively (study completers .66 and 1.08). In addition, parents in the intervention group reported less use of harsh and inconsistent discipline after the treatment, as well as more positive praise. Effects on behavior problems were maintained at 6-month follow-up.ConclusionsThe results support the efficacy of parent training, administered through Internet, with outcomes comparable to many of the group-based parent training programs. The efficacy, low cost, and higher accessibility make this intervention a fitting part in a stepped-care model.     

The relationship between acculturation preferences and prejudice: Longitudinal evidence from majority and minority groups in three European countries

A longitudinal field survey tested the reciprocal effects of acculturation preferences and prejudice among ethnic minorities and majorities. Data were collected at two points in time from 512 members of ethnic minorities and 1143 majority members in Germany, Belgium and England. Path analyses yielded not only the lagged effects of prejudice on acculturation preferences but also the reverse for both majority and minority members. The mutual longitudinal effects between prejudice and desire for culture maintenance were negative, and the mutual effects between prejudice and desire for culture adoption were positive for majority members. The reverse was the case for minority participants. Moreover, the two acculturation dimensions interacted in their effect on prejudice for majority participants but not for minority participants. The effect of desire for culture adoption on prejudice was moderated by perceived intergroup similarity. Theoretical and practical implications of the findings are discussed.

Relationships and the social brain: integrating psychological and evolutionary perspectives

Psychological studies of relationships tend to focus on specific types of close personal relationships (romantic, parent-offspring, friendship) and examine characteristics of both the individuals and the dyad. This paper looks more broadly at the wider range of relationships that constitute an individual's personal social world. Recent work on the composition of personal social networks suggests that they consist of a series of layers that differ in the quality and quantity of relationships involved. Each layer increases relationship numbers by an approximate multiple of 3 (5-15-50-150) but decreasing levels of intimacy (strong, medium, and weak ties) and frequency of interaction. To account for these regularities, we draw on both social and evolutionary psychology to argue that relationships at different layers serve different functions and have different cost-benefit profiles. At each layer, the benefits are asymptotic but the costs of maintaining a relationship at that level (most obviously, the time that has to be invested in servicing it) are roughly linear with the number of relationships. The trade-off between costs and benefits at a given level, and across the different types of demands and resources typical of different levels, gives rise to a distribution of social effort that generates and maintains a hierarchy of layered sets of relationships within social networks. We suggest that, psychologically, these trade-offs are related to the level of trust in a relationship, and that this is itself a function of the time invested in the relationship.
