Why did it happen to me? Social cognition processes in adjustment and recovery from criminal victimisation and illness

This article reviews the theoretical framework and empirical evidence for the hypothesised relationship between self-blame attributions and psychological adjustment. In doing so, an argument is presented that poses an alternative interpretation to that which is widely accepted regarding the complex relationship between blame attributions, perceived control, self-esteem, and recovery. A number of fundamental issues concerning the assumptions underlying Janoff-Bulman’s model are identified and explored. In particular, attention is given to the importance of distinguishing perceived control from likelihood of recurrence, and perceived control from outcome expectancy. Finally, the possibility that attributions may not play as fundamental a role in adjustment as first thought is considered, and future lines of enquiry are identified.     

Sex differences in impulsivity: a meta-analysis

Men are overrepresented in socially problematic behaviors, such as aggression and criminal behavior, which have been linked to impulsivity. Our review of impulsivity is organized around the tripartite theoretical distinction between reward hypersensitivity, punishment hyposensitivity, and inadequate effortful control. Drawing on evolutionary, criminological, developmental, and personality theories, we predicted that sex differences would be most pronounced in risky activities with men demonstrating greater sensation seeking, greater reward sensitivity, and lower punishment sensitivity. We predicted a small female advantage in effortful control. We analyzed 741 effect sizes from 277 studies, including psychometric and behavioral measures. Women were consistently more punishment sensitive (d = -0.33), but men did not show greater reward sensitivity (d = 0.01). Men showed significantly higher sensation seeking on questionnaire measures (d = 0.41) and on a behavioral risk-taking task (d = 0.36). Questionnaire measures of deficits in effortful control showed a very modest effect size in the male direction (d = 0.08). Sex differences were not found on delay discounting or executive function tasks. The results indicate a stronger sex difference in motivational rather than effortful or executive forms of behavior control. Specifically, they support evolutionary and biological theories of risk taking predicated on sex differences in punishment sensitivity. A clearer understanding of sex differences in impulsivity depends upon recognizing important distinctions between sensation seeking and impulsivity, between executive and effortful forms of control, and between impulsivity as a deficit and as a trait.     

Gender symmetry in intimate aggression: an effect of intimacy or target sex?

Men's greater use of direct aggression is not evident in studies of intimate partner aggression. In previous research, the effects of target sex and relationship intimacy have frequently been confounded. This study sought to examine these effects separately. One hundred and seventy-four participants (59 male and 115 female) read vignette scenarios in which they were provoked by a same-sex best friend, an opposite-sex best friend, and a partner. For each target, participants estimated their likely use of direct physical and verbal aggression as well as noninjurious forms of anger expression. Results showed that men lower their aggression in the context of an intimate partnership and that this is an effect of the target's sex. In contrast, women raise their aggression in the context of an intimate partnership and this is an effect of intimacy with the target. The use of noninjurious angry behavior did not vary between targets for either sex of the participant, which suggests that the effects of target are confined to behaviors which carry an intention to harm. Possible effects of social norms and oxytocin-mediated emotional disinhibition on intimate partner aggression are discussed.     

Specialised use of working memory by Portia africana,a spider-eating salticid

Using expectancy–violation methods, we investigated the role of working memory in the predatory strategy of Portia africana, a salticid spider from Kenya that preys by preference on other spiders. One of this predator’s tactics is to launch opportunistic leaping attacks on to other spiders in their webs. Focussing on this particular tactic, our experiments began with a test spider on a ramp facing a lure (dead prey spider mounted on a cork disc) that could be reached by leaping. After the test spider faced the lure for 30 s, we blocked the test spider’s view of the lure by lowering an opaque shutter before the spider leapt. When the shutter was raised 90 s later, either the same lure came into view again (control) or a different lure came into view (experimental: different prey type in same orientation or same prey type in different orientation). We recorded attack frequency (number of test spiders that leapt at the lure) and attack latency (time elapsing between shutter being raised and spiders initiating a leap). Attack latencies in control trials were not significantly different from attack latencies in experimental trials, regardless of whether it was prey type or prey orientation that changed in the experimental trials. However, compared with test spiders in the no-change control trials, significantly fewer test spiders leapt when prey type changed. There was no significant effect on attack frequency when prey orientation changed. These findings suggest that this predator represents prey type independently of prey orientation.     

The relations between cognitive ability and personality: Convergent results across measures

Several studies have investigated the relations between cognitive ability and Big Five personality constructs. The present study extended previous research by (a) examining these relationships in large samples (total N = 120,014), (b) including several measures of cognitive ability and personality, (c) examining both domain and facet-level personality scores, (d) expanding the personality domains studied to include Machiavellianism, and (e) correcting the observed correlations for range restriction and reliability to provide a better statistical estimate of the relations between the cognitive and personality scores and constructs. Results were consistent with prior research showing a positive relationship between cognitive ability and Openness and negative relationships between cognitive ability and Neuroticism and Conscientiousness. Negative relations between cognitive ability and Extraversion and Agreeableness also were observed. Machiavellianism, not part of the Big Five was found to have a positive correlation with cognitive ability. Of particular interest was the finding that the relations between cognitive ability and personality were affected by the specific content of the cognitive and personality measures. Cognitive measures with verbal content were more strongly correlated with personality than were cognitive measures with math or nonverbal content for all of the samples. Also, there was considerable variability in the cognitive-personality correlations for the facets underlying each personality domain. The variability in correlations at the facet-level implies that cognitive-personality relationships at the domain-level will vary as a function of the specific content of the cognitive and personality measures. Overall, the results provide support for cognitive-personality association at the measurement level.     

Naturalist Political Realism and the First Political Question

Many political realists reject the idea that the first task for political philosophy is to justify the existence of coercive political institutions (CPIs). Instead, they say, we should begin with the factual existence of CPIs, and ask how they ought to be structured. In holding this view, they adopt a form of political naturalism that is broadly Aristotelian in character. In this article, I distinguish between two forms that this political naturalism might take ‐ what I call a ‘strong’ form, and a ‘weak’ form ‐ and argue that both ought to be rejected. 1     

A temporally distinct role for group I and group II metabotropic glutamate receptors in object recognition memory

Recognition memory, involving the ability to discriminate between a novel and familiar object, depends on the integrity of the perirhinal cortex (PRH). Glutamate, the main excitatory neurotransmitter in the cortex, is essential for many types of memory processes. Of the subtypes of glutamate receptor, metabotropic receptors (mGluRs) have received less study than NMDA receptors; thus, the reported experiments examined the role of mGluRs in familiarity discrimination in the rat PRH. Experiments 1 and 2 assessed the effects of systemic administration of MPEP, a group I mGluR (specifically mGluR5) antagonist, and/or LY341495, a group II mGluR antagonist, on a spontaneous object novelty preference task. Simultaneous antagonism of both group I and II mGluRs impaired familiarity discrimination following a 24-h but not a 15-min delay, while antagonism of either mGluR subtype alone had no effect at either delay. The impairment was in acquisition, as in Experiment 3 coadministration of MPEP and LY341495 did not affect recognition memory performance when administered either after the sample phase or prior to test. The impairment in long-term recognition memory was mediated by mGluRs in the PRH, as localized intracortical antagonism of group I and II mGluRs also produced a deficit (Experiment 4). No evidence was found for an involvement of group III mGluRs in the acquisition of long-term familiarity discrimination (Experiment 5). These findings establish that glutamatergic neurotransmission in the PRH via group I and II mGluRs is crucial for the acquisition, but not for the consolidation or retrieval of long-term object recognition memory.
