Understanding Obsessive–Compulsive Disorder: Focus on Decision Making

Current approaches to obsessive-compulsive disorder (OCD) have suggested that neurobiological abnormalities play a crucial role in the etiology and course of this psychiatric illness. In particular, a fronto-subcortical circuit, including the orbitofrontal cortex, basal ganglia and thalamus appears to be involved in the expression of OCD symptoms. Neuropsychological studies have also shown that patients with OCD show deficits in cognitive abilities that are strictly linked to the functioning of the frontal lobe and its related fronto-subcortical structures, such as executive functioning deficits and insufficient cognitive-behavioral flexibility. This article focuses on decision making, an executive ability that plays a crucial role in many real-life situations, whereby individuals choose between pursuing strategies of action that involve only immediate reward and others based on long-term reward. Although the role of decision-making deficits in the evolution of OCD requires further research, the collected findings have significant implications for understanding the clinical and behavioral heterogeneity that characterizes individuals with OCD.     

Influence of the instructions on the performance and establishment of memorization strategies in space judgments

Studies of visual space perception have been assuming that people have an internal representation of the physical space that surrounds them. A variety of psychophysical procedures has been used in an attempt to measure the properties of visual space. The goal of the present study was to evaluate the accuracy of the mental representation and the strategies adopted to acquire and retain visuo-spatial information of a configuration as a function of two types of instructions. Thirty-eight undergraduate and graduate students participated in the study and were distributed in perceptive and mnemonic experimental conditions. The effect of the instructions (intentional and incidental) on the representation of the distances among the objects of the scene was estimated using exponents of power function, based on the reproduction of the distances among the stimuli of the scene. The results revealed that judgments made under intentional instructions were more frequently based on strategies related to the location of the stimuli, whereas judgments originating from incidental instructions were based on strategies related to the name of the stimuli. It was observed that the intentional instruction facilitated a more accurate mental representation of the observed experimental configuration, enhancing participants' performance.     

Masculine girls and feminine boys: genetic and environmental contributions to atypical gender development in early childhood

In this genetic study of atypical gender role development, parents of 5,799 twin pairs, ages 3 and 4, rated their twin children's masculinity and femininity. Boys were selected as gender atypical if they were highly feminine (top 5%, 10%, or 15%) relative to other boys, and girls were selected if they were highly masculine relative to other girls. Gender-atypical boys and girls were each divided into 2 groups: fully gender atypical (e.g., feminine boys also low on masculinity) and partially gender atypical (e.g., feminine boys who are not low on masculinity). DeFries-Fulker (DF; J. C. DeFries & D. W. Fulker, 1985, 1988) extremes analysis yielded moderate group heritability and substantial shared environment effects for atypical gender role behavior. However, for fully gender-atypical girls, group heritability accounted for most of the variance, and shared environment had no effect. The results are discussed in light of past studies and potential implications for atypical gender development.     

Research off the couch: Re-visiting the transsexual conundrum

This paper outlines the findings of a qualitative study involving interviews with eight transsexual individuals who had volunteered to take part in a television (TV) documentary about transsexuality. The participants were interviewed before taking part in the documentary and after its screening on national TV. The author proposes that for either biological and/or psychological reasons, some transsexual individuals experience early on a profound and disturbing incongruence at the level of the bodily self. In turn, this experience of incongruity is not contingently mirrored by primary attachment figures and remains unmentalized, thus disrupting self-coherence. In an attempt to restore self-coherence, the individual searches for the ‘right’ body that is anticipated to relieve the felt incongruity. The way this modified body relieves the incongruity is through the certainty it imparts that the image in the ‘mirror’ will match the subjective experience of the body. In this study, the experience of being mirrored through the group process during filming and the audience's response to the TV series, which was very positive, appeared to be associated with an attenuation in the urgency with which planned body modifications were being discussed post-TV screenings.     

Focused attention improves working memory: implications for flexible-resource and discrete-capacity models

Performance in working memory (WM) tasks depends on the capacity for storing objects and on the allocation of attention to these objects. Here, we explored how capacity models need to be augmented to account for the benefit of focusing attention on the target of recall. Participants encoded six colored disks (Experiment 1) or a set of one to eight colored disks (Experiment 2) and were cued to recall the color of a target on a color wheel. In the no-delay condition, the recall-cue was presented after a 1,000-ms retention interval, and participants could report the retrieved color immediately. In the delay condition, the recall-cue was presented at the same time as in the no-delay condition, but the opportunity to report the color was delayed. During this delay, participants could focus attention exclusively on the target. Responses deviated less from the target’s color in the delay than in the no-delay condition. Mixture modeling assigned this benefit to a reduction in guessing (Experiments 1 and 2) and transposition errors (Experiment 2). We tested several computational models implementing flexible or discrete capacity allocation, aiming to explain both the effect of set size, reflecting the limited capacity of WM, and the effect of delay, reflecting the role of attention to WM representations. Both models fit the data better when a spatially graded source of transposition error is added to its assumptions. The benefits of focusing attention could be explained by allocating to this object a higher proportion of the capacity to represent color.

On receiving what has gone astray, on finding what has got lost

Disturbing emotions that act as bodily cryptograms waiting to be deciphered are currently understood as intra-psychic trauma. The author briefly discusses Fordham's concepts of deintegration and primitive identity, as well as early patterns of mother-infant attunement to describe how the empathic capacity of the analyst is dramatically challenged in helping patients to give birth to unbearable emotions that remain an undifferentiated entity. Referring to Ogden's understanding of the mechanism of projective identification, the author will explore how unconscious mental processes in the analyst and the patient can work at re-activating failures in the deintegrative process. Clinical material is presented to show how unconscious psychic events that affect the patient but cannot be known consciously can be born into mind by the analytic couple.     

Transgenerational transmission of indigestible facts: from trauma,deadly ghosts and mental voids to meaning‐making interpretations

Abstract: In this paper¹ I will discuss clinical material and make some hypotheses on how to work with patients for whom trans‐generational transmission of trauma is an issue. Basing my hypothesis on two clinical cases, I will propose a way of dealing with undigested facts, the fabric of trauma, which generate deadly ghosts and mental voids that are transmitted from one generation to the next. I will propose a way of formulating interpretations for the unthinkable to become thinkable and find a representation in the mind of patients who suffer from transgenerationally transmitted trauma. Some thoughts will be given to the maternal and the paternal transmitters of trauma in relation to child development issues.
