Prevalence of Types of Perpetration: Gender and Patterns of Intimate Partner Violence Within a Prison Sample in Singapore

It has been reported in Western research on intimate partner violence (IPV) that there are similar rates between males and females (Filbert, 2010). The objective of this study was to compare male and female prisoners from Singapore on rates of IPV as well as the Johnson (2006) types of IPV. Women (n = 75) self-reported higher rates of physical IPV perpetration in the past year (64.0%) than (n = 75) did men (46.1%). Women reported similar rates of IPV for themselves and their partners in the past year (64.0%), while men reported slightly more physical IPV for themselves (46.1%) than they did for their female partners (41.3%). In line with Johnson (2006), rates of intimate terrorism were calculated between 5% and 7% for themselves and their partners, with little variation due to gender. Violent resistance (VR) was calculated at between 2.1% and 7%, with more female than male VR reported for women. Much higher rates of situational couple violence was calculated for both males and females, ranging from 53.3% to 66.7% in the past year, while mutual violent control was significantly lower, ranging from between 14.8% to 20.0%, with data being discussed in relation to patriarchal and family violence perspectives. We concluded that the rates of IPV between males and females were very similar as were the types of IPV. Further research with other cultures should be encouraged for comparison with Western samples.     

Twin Inc.

This paper presents an account of how human spontaneous embryonic chimeras are formed. On the prevalent view in the philosophical literature, it is said that chimeras are the product of two embryos that fuse to form a new third embryo. We call this version of fusion synthesis. In contrast to synthesis, we present an alternative mechanism for chimera formation called incorporation, wherein one embryo incorporates the cells of a second embryo into its body. We argue that the incorporation thesis explains other types of chimera formation, which are better understood, and is more consistent than synthesis with what is known about embryological development. Incorporation also has different implications than synthesis and so avoids the philosophical puzzles that are often said to accompany embryonic chimera formation—puzzles which pose problems to the human embryo’s persistence from fertilization to the fetal stage of human development.     

Food approach conditioning and discrimination learning using sound cues in benthic sharks

The marine environment is filled with biotic and abiotic sounds. Some of these sounds predict important events that influence fitness while others are unimportant. Individuals can learn specific sound cues and ‘soundscapes’ and use them for vital activities such as foraging, predator avoidance, communication and orientation. Most research with sounds in elasmobranchs has focused on hearing thresholds and attractiveness to sound sources, but very little is known about their abilities to learn about sounds, especially in benthic species. Here we investigated if juvenile Port Jackson sharks could learn to associate a musical stimulus with a food reward, discriminate between two distinct musical stimuli, and whether individual personality traits were linked to cognitive performance. Five out of eight sharks were successfully conditioned to associate a jazz song with a food reward delivered in a specific corner of the tank. We observed repeatable individual differences in activity and boldness in all eight sharks, but these personality traits were not linked to the learning performance assays we examined. These sharks were later trained in a discrimination task, where they had to distinguish between the same jazz and a novel classical music song, and swim to opposite corners of the tank according to the stimulus played. The sharks’ performance to the jazz stimulus declined to chance levels in the discrimination task. Interestingly, some sharks developed a strong side bias to the right, which in some cases was not the correct side for the jazz stimulus.     

Liberating narratives and the play of unforbidden pleasures: In brief dynamic therapy

Drawing upon the work of Adam Phillips and Ronald Britton the author highlights the intimidating and fear-inducing nature of the super-ego and the role of the therapist in supporting the judgements of the ego and liberating it from the domination of the super-ego. He goes on to explore the proposition that moral principles do not need to be oppressive in nature and that they can emanate from objects that are more akin to sexual or aesthetic objects. These themes are linked to Woodmansey’s conceptualistion of the punitive and humiliating super-ego, and the origin of the super-ego as an internalisation of an external conflict is outlined. The role of identifying a Cyclical Maladaptive Pattern as a focus and its contribution in identifying the super-ego and how it manifests in the client’s narrative are explored, as well as the crucial contribution of a playful stance on the part of therapist in subverting and undermining the intimidating strictures of the super-ego.     

Motivational deficits in schizophrenia relate to abnormalities in cortical learning rate signals

Individuals from across the psychosis spectrum display impairments in reinforcement learning. In some individuals, these deficits may result from aberrations in reward prediction error (RPE) signaling, conveyed by dopaminergic projections to the ventral striatum (VS). However, there is mounting evidence that VS RPE signals are relatively intact in medicated people with schizophrenia (PSZ). We hypothesized that, in PSZ, reinforcement learning deficits often are not related to RPE signaling per se but rather their impact on learning and behavior (i.e., learning rate modulation), due to dysfunction in anterior cingulate and dorsomedial prefrontal cortex (dmPFC). Twenty-six PSZ and 23 healthy volunteers completed a probabilistic reinforcement learning paradigm with occasional, sudden, shifts in contingencies. Using computational modeling, we found evidence of an impairment in trial-wise learning rate modulation (α) in PSZ before and after a reinforcement contingency shift, expressed most in PSZ with more severe motivational deficits. In a subsample of 22 PSZ and 22 healthy volunteers, we found little evidence for between-group differences in VS RPE and dmPFC learning rate signals, as measured with fMRI. However, a follow-up psychophysiological interaction analysis revealed decreased dmPFC-VS connectivity concurrent with learning rate modulation, most prominently in individuals with the most severe motivational deficits. These findings point to an impairment in learning rate modulation in PSZ, leading to a reduced ability to adjust task behavior in response to unexpected outcomes. At the level of the brain, learning rate modulation deficits may be associated with decreased involvement of the dmPFC within a greater RL network.     

Using Relational-cultural Theory to Negotiate Relational Rebuilding in Survivors of Intimate Partner Violence

In this article, the authors describe the application of relational-cultural theory (RCT) for survivors of intimate partner violence (IPV). RCT’s philosophical foundation and core processes work effectively within the context of the counseling session. Through the RCT lens, the authors examine how the theory’s approaches can be utilized for relational rebuilding. Finally, RCT strategies are included for working with women who have experienced shame and relational disconnections as the result of IPV.     

Mental health practitioners' attitudes towards transgender people: A systematic review of the literature

Background: A systematic review was conducted to critically evaluate and synthesize literature investigating mental health practitioners' attitudes towards transgender people.

Objective: Three primary objectives were outlined; first, establish whether overall attitudes are positive or negative. Second, explore whether training, education or experience influences attitudes and finally, examine participant demographics in relation to attitude trends.

Method: A systematic electronic search was carried out in March 2017 using Medline, PsycINFO, PsycArticles, CINAHL, ASSIA, and Web of Science electronic databases. Manual citation and ancestral searches were conducted on identified papers. Qualitative, quantitative and mixed method studies were eligible for inclusion. A total of 13 papers of mixed quality were identified.

Results: Existing literature is limited to cross-sectional, quantitative data and fails to investigate differences between implicit and explicit attitudes. Small to moderate convenience samples reduce the generalizability of data. Overall attitudes were positive although negative attitudes were more frequent in male, Caucasian, heterosexual, religious, conservative mental health professionals.

Conclusions: Refined scales are needed to address the unique heterogeneity within transgender populations. Future research should focus on how attitudes impact care provided and employ longitudinal designs to explore the sustainability of targeted attitudinal training.     

Theory of mind: The state of the art*

Abstract

In this article, I reflect on theory of mind as a field (ToM), how it has developed over the years, and focally on the state of current research and theory. Having begun with preschoolers’ understanding of beliefs and desires, the field now includes research from infancy through late life, contributions and contributors from around the world, research on behavior, conversation, neural correlates, gene-environment contributions, evolution, and the social-behavioral antecedents and consequences of the unfolding trajectories of ToM understanding. Several topics in particular portray the current state of the art and my sense of where theory-of-mind research is likely to head in the near future: progressions of theory of mind achievement; cultural experiences plus experiential influences that shape developmental trajectories; developmental cognitive neuroscience; infant ToM insights; research on ToM developments beyond preschool, including children’s increasing interest in and wrestling with extraordinary minds, such as those of God and super-heroes.     

Multiple layers of information processing in deductive reasoning: combining dual strategy and dual-source approaches to reasoning

The idea that inferential performance cannot be analyzed within a single model has been suggested within two theoretical contexts. The dual strategy model suggests that people reason using different approaches to processing statistical information. The dual-source model suggests that people reason probabilistically using both statistical information and some intuition about logical form. Each model suggests that people have different approaches to processing information while making inferences. The following studies examined whether these different forms of information processing were equally present during reasoning. Participants were given a series of problems designed to distinguish counterexample from statistical reasoners. They were then given a series of MP or AC inferences for which identical statistical information was provided. Results show that MP inferences were considered to be deductively valid more often than equivalent AC inferences. The effect of logical form was independent of reasoning strategy, and of relatively equivalent size for both counterexample and statistical reasoners. The second study examined explicitly probabilistic inferences, and showed smaller effects of logical form and of reasoning strategy, although with a complex set of interactions. These results show that understanding the way that people use information when making inferences requires a multidimensional approach.
