One size does not fit all: face emotion processing impairments in semantic dementia, behavioural-variant frontotemporal dementia and Alzheimer's disease are mediated by distinct cognitive deficits

Patients with frontotemporal dementia (both behavioural variant [bvFTD] and semantic dementia [SD]) as well as those with Alzheimer's disease (AD) show deficits on tests of face emotion processing, yet the mechanisms underlying these deficits have rarely been explored. We compared groups of patients with bvFTD (n = 17), SD (n = 12) or AD (n = 20) to an age- and education-matched group of healthy control subjects (n = 36) on three face emotion processing tasks (Ekman 60, Emotion Matching and Emotion Selection) and found that all three patient groups were similarly impaired. Analyses of covariance employed to partial out the influences of language and perceptual impairments, which frequently co-occur in these patients, provided evidence of different underlying cognitive mechanisms. These analyses revealed that language impairments explained the original poor scores obtained by the SD patients on the Ekman 60 and Emotion Selection tasks, which involve verbal labels. Perceptual deficits contributed to Emotion Matching performance in the bvFTD and AD patients. Importantly, all groups remained impaired on one task or more following these analyses, denoting a primary emotion processing disturbance in these dementia syndromes. These findings highlight the multifactorial nature of emotion processing deficits in patients with dementia.     

Youth Psychopathic Traits Inventory-Short Version: A Further Test of the Internal Consistency and Criterion Validity

The Youth Psychopathic Traits Inventory-Short Version (YPI-S; van Baardewijk et al., 2010) is a self-report measure to assess psychopathic-like traits in adolescents. The aim of the present study is to investigate the factor structure, the internal consistency, and the criterion validity of the YPI-S in 768 Belgian community adolescents (45.4?% males). In general, our study supported the YPI three factor structure while relevant indices showed that the instrument is internally consistent. In addition, relations between the YPI-S total score and dimension scores on the one hand and external criterion measures (e.g. conduct problems and self-reported offending) on the other hand were generally in line with predictions. The present study replicated and substantially extended previous findings of the YPI-S in a sample of community youth. Future studies are needed to test whether findings from community samples can be replicated in clinical-referred and justice-involved boys and adolescents.     

Disturbance of Emotion Processing in Frontotemporal Dementia: A Synthesis of Cognitive and Neuroimaging Findings

Accurate processing of emotional information is a critical component of appropriate social interactions and interpersonal relationships. Disturbance of emotion processing is present in frontotemporal dementia (FTD) and is a clinical feature in two of the three subtypes: behavioural-variant FTD and semantic dementia. Emotion processing in progressive nonfluent aphasia, the third FTD subtype, is thought to be mostly preserved, although current evidence is scant. This paper reviews the literature on emotion recognition, reactivity and expression in FTD subtypes, although most studies focus on emotion recognition. The relationship between patterns of emotion processing deficits and patterns of neural atrophy are considered, by integrating evidence from recent neuroimaging studies. The review findings are discussed in the context of three contemporary theories of emotion processing: the limbic system model, the right hemisphere model and a multimodal system of emotion. Results across subtypes of FTD are most consistent with the multimodal system model, and support the presence of somewhat dissociable neural correlates for basic emotions, with strongest evidence for the emotions anger and sadness. Poor emotion processing is evident in all three subtypes, although deficits are more widespread than what would be predicted based on studies in healthy cohorts. Studies that include behavioural and imaging data are limited. Future investigations combining these approaches will help improve the understanding of the neural network underlying emotion processing. Presently, longitudinal investigations of emotion processing in FTD are lacking, and studies investigating emotion processing over time are critical to understand the clinical manifestations of disease progression in FTD.     

A lexical analysis of environmental sound categories

In this article we report on listener categorization of meaningful environmental sounds. A starting point for this study was the phenomenological taxonomy proposed by Gaver (1993b). In the first experimental study, 15 participants classified 60 environmental sounds and indicated the properties shared by the sounds in each class. In a second experimental study, 30 participants classified and described 56 sounds exclusively made by solid objects. The participants were required to concentrate on the actions causing the sounds independent of the sound source. The classifications were analyzed with a specific hierarchical cluster technique that accounted for possible cross-classifications, and the verbalizations were submitted to statistical lexical analyses. The results of the first study highlighted 4 main categories of sounds: solids, liquids, gases, and machines. The results of the second study indicated a distinction between discrete interactions (e.g., impacts) and continuous interactions (e.g., tearing) and suggested that actions and objects were not independent organizational principles. We propose a general structure of environmental sound categorization based on the sounds' temporal patterning, which has practical implications for the automatic classification of environmental sounds.     

Improving communicative understanding: The benefits of global processing

The current research investigated whether a global processing style, affording a focus on the broader context, promotes communicative understanding and, in turn, communicative success. Results confirmed that compared to priming local processing, priming global processing enhanced the deciphering of potentially sarcastic statements of which participants were the receivers (Experiment 1). Experiment 2 extended these findings to oral communication: Global processing increased the correct deciphering of meanings that speakers’ attempted to convey by ambiguous sentences to listeners. Overall ‘seeing the forest instead of the trees’ allowed receivers to attend more perceptively to the larger communicative context, thereby facilitating successful communication.     

L-eye to me: the combined role of Need for Cognition and facial trustworthiness in mimetic desires

Recent studies showed that stimuli are evaluated more favourably when they are perceived to capture others' attention, an effect coined "mimetic desire". The aim of the present research was to examine the combined role of Need for Cognition and target's facial trustworthiness in this effect. Participants saw movie excerpts of trustworthy and untrustworthy 3D faces (Oosterhof & Todorov, 2008) turning their attention towards one art painting and away from another art painting. Results showed that looked-at paintings were preferred to looked-away paintings when associated with a trustworthy face. However, the reversed finding was observed for paintings associated with untrustworthy faces. The latter interaction was in turn moderated by participant's Need for Cognition, with a larger reversal effect for participants scoring lower on the NFC scale. Theoretical implications of these findings are discussed.     

On Epistemological Shifts and Good Old French Wine (in New Bottles): Commentary on Elcheroth,Doise, and Reicher

In this article, we first suggest that the approach presented by Elcheroth, Doise, and Reicher is particularly relevant in view of the “neuroscientific turn” that faces political psychology. Thus, we note that the distinction between content and process and the predilection for general, intrapsychological, and content‐free explanations of political cognition and behavior are encouraged by these developments. We contrast the contribution of the social representations approach to the understanding of social conflict and social change with the approach promoted by these new perspectives. Next, we consider the four themes highlighted by Elcheroth et al. as distinctive of the social representations approach. We notice convergences between these themes and several areas of “mainstream” social and political psychology and show that several of these themes have surfaced in these fields without making reference to this approach.     

Preparation of forefinger’s sequence on keyboard orients ocular fixations on computer screen

This study examined the links between attention, hand movements and eye movements when performed in different spatial areas. Participants performed a visual search task on a computer screen while preparing to press two keyboard keys sequentially with their index. Results showed that the planning of the manual sequence influenced the latency of the first saccade and the placement of the first fixation. In particular, even if the first fixation placement was influenced by the combination of both components of the prepared manual sequence in some trials, it was affected principally by the first component of the prepared manual sequence. Moreover, the probability that the first fixation placement did reflect a combination of both components of the manual sequence was correlated with the speed of the second component. This finding suggests that the preparation of the second component of the sequence influence simultaneous oculomotor behavior when motor control of the manual sequence relied on proactive motor planning. These results are discussed taking into account the current debate on the eye/hand coordination research.     

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.
