Wings of desire: Reflections on sexual desire,identity and freedom

The aim of this paper is to give a critical discussion of Sartre’s concept of sexual desire and its relation to self-identity and freedom. Why Sartre? Sartre is one of very few philosophers who offers a systematic account of sexual desire. He has influenced eminent philosophical concepts of sexual desire held by, for instance, de Beauvoir, Lacan, Foucault, Levinas, Irigaray and Butler, but not much is written about his own notion of sexual desire. This alone is reason to explore Sartre’s view. What makes his view of sexual desire particularly interesting is that it is framed by his theory of freedom. Sartre offers the original, radical notion that freedom is absolute. Because consciousness is never self-identical, he argues, human identity is not fixed. Instead, we are consequently nothing else but what we keep desiring to make of ourselves. He concludes that we are always free to choose our drives and desires, even what seem to be our most enslaving, natural sexual instincts. The question raised in this article, however, concerns what the nature of sexual desire is and how free we really are to choose our sexual desires. I first contextualise Sartre’s view of sexual desire within his notion of desire in general and its relation to instinct, drive, consciousness, freedom and identity. Then, I give a detailed discussion of his analysis of sexual desire, its relation to freedom, and, what Sartre calls its failures. Finally, I discuss a critique of, and alternative to, Sartre’s theory of sexual desire from the perspective of my own notion of heteronomous and autonomous desire and freedom.     

French Validation of the Overexcitability Questionnaire 2: Psychometric Properties and Factorial Structure

Overexcitability corresponds to an overall response to stimulations in 5 domains: psychomotor, sensual, intellectual, imaginational, and emotional. The aim of this study was to develop a French version of the Overexcitability Questionnaire 2 (OEQ2) and to expand its psychometric properties. Two studies were conducted: one with a sample of 474 adolescents and another with a sample of 436 adults. Internal consistency, factorial structure, and validity (correlations with intelligence, personality, and alexithymia) were examined. The French OEQ2 showed satisfactory psychometric properties, thus advocating for its use in further research on overexcitability and in clinical practice.     

Individuation training with other‐race faces reduces preschoolers’ implicit racial bias: a link between perceptual and social representation of faces in children

The present study examined whether perceptual individuation training with other‐race faces could reduce preschool children's implicit racial bias. We used an ‘angry = outgroup’ paradigm to measure Chinese children's implicit racial bias against African individuals before and after training. In Experiment 1, children between 4 and 6 years were presented with angry or happy racially ambiguous faces that were morphed between Chinese and African faces. Initially, Chinese children demonstrated implicit racial bias: they categorized happy racially ambiguous faces as own‐race (Chinese) and angry racially ambiguous faces as other‐race (African). Then, the children participated in a training session where they learned to individuate African faces. Children's implicit racial bias was significantly reduced after training relative to that before training. Experiment 2 used the same procedure as Experiment 1, except that Chinese children were trained with own‐race Chinese faces. These children did not display a significant reduction in implicit racial bias. Our results demonstrate that early implicit racial bias can be reduced by presenting children with other‐race face individuation training, and support a linkage between perceptual and social representations of face information in children.     

Hippocampal train stimulation modulates recall of fear extinction independently of prefrontal cortex synaptic plasticity and lesions

It has been shown that long-term potentiation (LTP) develops in the connection between the mediodorsal thalamus (MD) and the medial prefrontal cortex (mPFC) and between the hippocampus (HPC) and the mPFC following fear extinction, and correlates with extinction retention. However, recent lesion studies have shown that combined lesions of the MD and mPFC do not interfere with extinction learning and retention, while inactivation of the dorsal HPC disrupts fear extinction memory. Here we found in rats that immediate post-training HPC low-frequency stimulation (LFS) suppressed extinction-related LTP in the HPC-mPFC pathway and induced difficulties in extinction recall. HPC tetanus, applied several hours later, failed to re-establish mPFC LTP but facilitated recall of extinction. Delayed post-training HPC LFS also provoked mPFC depotentiation and difficulties with extinction recall. HPC tetanus abolished these two effects. We also found that damage to the mPFC induced fear return only in rats that received HPC LFS following extinction training. HPC tetanus also reversed this behavioral effect of HPC LFS in lesioned rats. These data suggest that the HPC interacts with the mPFC during fear extinction, but can modulate fear extinction independently of this interaction.     

Holistic processing is finely tuned for faces of one's own race

Recognizing individual faces outside one's race poses difficulty, a phenomenon known as the other-race effect. Most researchers agree that this effect results from differential experience with same-race (SR) and other-race (OR) faces. However, the specific processes that develop with visual experience and underlie the other-race effect remain to be clarified. We tested whether the integration of facial features into a whole representation-holistic processing-was larger for SR than OR faces in Caucasians and Asians without life experience with OR faces. For both classes of participants, recognition of the upper half of a composite-face stimulus was more disrupted by the bottom half (the composite-face effect) for SR than OR faces, demonstrating that SR faces are processed more holistically than OR faces. This differential holistic processing for faces of different races, probably a by-product of visual experience, may be a critical factor in the other-race effect.
