The Association between Attachment Styles and Physical Intimate Partner Violence Perpetration and Victimization: A Meta‐Analysis

In this meta‐analysis, we examine attachment styles—something commonly incorporated into couples therapy—and their association with physical intimate partner violence (IPV) perpetration and victimization among men and women. This meta‐analysis incorporated 33 studies that looked at the association between four different attachment styles and IPV. This study examined the strength of the correlation among different attachment styles and IPV perpetration and victimization, examined gender differences in the strength of the association among attachment styles and IPV, and compared the strength of the association with IPV among different attachment styles. We found that anxious attachment, avoidant attachment, and disorganized attachment styles were all significantly associated with physical IPV perpetration and victimization. Secure attachment was significantly negatively related to IPV perpetration and victimization. There was a significantly stronger association between avoidant attachment and IPV victimization for women compared to men. Clinical implications related to the importance of fostering secure attachments when working with couples or individuals who have experienced IPV are addressed.     

A preliminary exploration of predictors of outcome and cognitive mechanisms of change in cognitive behaviour therapy for psychosis in people not taking antipsychotic medication

BackgroundCognitive behaviour therapy (CBT) has been shown to be effective in an open trial for people with psychotic disorders who have not been taking antipsychotic medication. There is little known about predictors of outcome in CBT for psychosis and even less about hypothesised mechanisms of change.Method20 participants with schizophrenia spectrum disorders received CBT in an exploratory trial. Our primary outcome was psychiatric symptoms measured using the PANSS. Secondary outcomes were dimensions of hallucinations and delusions, self-rated recovery and social functioning, and hypothesised mechanisms of change included appraisals of psychotic experiences, dysfunctional attitudes and cognitive insight. We also measured patient characteristics that may be associated with outcome.ResultsT-tests revealed that several of the hypothesised mechanisms did significantly change over the treatment and follow-up periods. Correlational analyses showed that reductions in negative appraisals of psychotic experiences were related to improvements on outcome measures and that shorter duration of psychosis and younger age were associated with greater changes in symptoms.ConclusionsCBT based on a specific cognitive model appears to change the hypothesised cognitive mechanisms, and these changes are associated with good outcomes. CBT may be more effective for those who are younger with shorter histories of psychosis.     

When seeing is knowing: the role of visual cues in the dissociation between children's rule knowledge and rule use

The Dimensional Change Card Sort (DCCS) task requires children to switch from sorting cards based on shape or color to sorting based on the other dimension. Typically, 3-year-olds perseverate, whereas 4-year-olds flexibly sort by different dimensions. Zelazo and colleagues (1996, Cognitive Development, 11, 37-63) asked children questions about the postswitch rules and found an apparent dissociation between rule knowledge and rule use, namely that 3-year-olds demonstrate accurate knowledge of the postswitch rules despite sorting cards incorrectly. Here, we show that children's success with these questions is grounded in their use of available visual cues; children who fail sorting use the target cards to correctly answer questions, and when the cards are unavailable they guess. This suggests that there might not be a dissociation between children's rule knowledge and rule use in the DCCS.     

What ‘biological racial realism’ should mean

A curious ambiguity has arisen in the race debate in recent years. That ambiguity is what is actually meant by ??biological racial realism??. Some philosophers mean that ??race is a natural kind in biology??, while others mean that ??race is a real biological kind??. However, there is no agreement about what a natural kind or a real biological kind should be in the race debate. In this article, I will argue that the best interpretation of ??biological racial realism?? is one that interprets ??biological racial realism?? as ??race is a genuine kind in biology??, where a genuine kind is a valid kind in a well-ordered scientific research program. I begin by reviewing previous interpretations of ??biological racial realism?? in the race debate. Second, I introduce the idea of a genuine kind and compare it to various notions of natural and real biological kinds used in the race debate. Third, I present and defend an argument for my view. Fourth, I provide a few interesting consequences of my view for the race debate. Last, I provide a summary of the article.     

Schools as Ethical or Schools as Political? Habermas Between Dewey and Rawls

Education is oftentimes understood as a deeply ethical practice for the development of the person. Alternatively, education is construed as a state-enforced apparatus for inculcation of specific codes, conventions, beliefs, and norms about social and political practices. Though holding both of these beliefs about education is not necessarily mutually contradictory, a definite tension emerges when one attempts to articulate a cogent theory involving both. I will argue in this paper that Habermas’s theory of discourse ethics, when combined with his statements on constitutional democracy and law, manifests this tension for formal education. Through a contrast with Dewey’s social-liberal view of education on the one hand, and the procedural liberalism and its associated view of education, common to Rawls and others writing in the contemporary Anglo-American tradition on the other, the questions of what this means for education and why it matters are raised and addressed.     

Kv4.2 knockout mice have hippocampal-dependent learning and memory deficits

Kv4.2 channels contribute to the transient, outward K(+) current (A-type current) in hippocampal dendrites, and modulation of this current substantially alters dendritic excitability. Using Kv4.2 knockout (KO) mice, we examined the role of Kv4.2 in hippocampal-dependent learning and memory. We found that Kv4.2 KO mice showed a deficit in the learning phase of the Morris water maze (MWM) and significant impairment in the probe trial compared with wild type (WT). Kv4.2 KO mice also demonstrated a specific deficit in contextual learning in the fear-conditioning test, without impairment in the conditioned stimulus or new context condition. Kv4.2 KO mice had normal activity, anxiety levels, and prepulse inhibition compared with WT mice. A compensatory increase in tonic inhibition has been previously described in hippocampal slice recordings from Kv4.2 KO mice. In an attempt to decipher whether increased tonic inhibition contributed to the learning and memory deficits in Kv4.2 KO mice, we administered picrotoxin to block GABA(A) receptors (GABA(A)R), and thereby tonic inhibition. This manipulation had no effect on behavior in the WT or KO mice. Furthermore, total protein levels of the α5 or δ GABA(A)R subunits, which contribute to tonic inhibition, were unchanged in hippocampus. Overall, our findings add to the growing body of evidence, suggesting an important role for Kv4.2 channels in hippocampal-dependent learning and memory.
