Segmenting the body into parts: Evidence from biases in tactile perception

How do we individuate body parts? Here, we investigated the effect of body segmentation between hand and arm in tactile and visual perception. In a first experiment, we showed that two tactile stimuli felt farther away when they were applied across the wrist than when they were applied within a single body part (palm or forearm), indicating a “category boundary effect”. In the following experiments, we excluded two hypotheses, which attributed tactile segmentation to other, nontactile factors. In Experiment 2, we showed that the boundary effect does not arise from motor cues. The effect was reduced during a motor task involving flexion and extension movements of the wrist joint. Action brings body parts together into functional units, instead of pulling them apart. In Experiments 3 and 4, we showed that the effect does not arise from perceptual cues of visual discontinuities. We did not find any segmentation effect for the visual percept of the body in Experiment 3, nor for a neutral shape in Experiment 4. We suggest that the mental representation of the body is structured in categorical body parts delineated by joints, and that this categorical representation modulates tactile spatial perception.     

Similarity is closeness: Metaphorical mapping in a conceptual task

The conceptual metaphor theory states that abstract concepts are represented by image schemas from concrete domains. In the present study we investigated the mapping for SIMILARITY IS CLOSENESS using tasks with nonlinguistic materials. In Experiments 1 and 2 participants decided whether two squares were similar or dissimilar in colour. The spatial distance between the squares was varied. Performance to similar colours was better at shorter distances, whereas performance to dissimilar colours was better at longer distances. In Experiments 3 and 4 participants made distance decisions to similar and dissimilar colours squares. Performance was not affected by similarity. These results show that metaphorical mappings can be found even beyond the context of linguistic metaphors and that the mapping between SIMILARITY and CLOSENESS is asymmetrical.

Can men talk about problems with weight? The therapeutic implications of a discourse analytic study

This paper discusses the implications for counsellors of a discourse analytic study examining men's talk about body weight. It is argued that research in the area of problems with body has neglected the growing pressures on men to manage body as a feature of self. This research perpetuates the dominant discursive construction of men's relationship to body as unproblematic — a construction that may present many barriers to men in seeking help for any distress encountered. An analysis of men's talk is discussed in terms of the expectation that body is not problematic and the observable downplaying of any concerns acknowledged. The accountability of body as a site of regulation also emerges within the extracts presented. It is argued that this property within the accounts resonates with work highlighting the growing pressures on men to exercise control over body. The contradictions between the two discourses identified are discussed in terms of their therapeutic implications. It is postulated that male distress emerging from the growing pressures to maintain body weight may be neglected within primary care and therapeutic domains if discourses formulating such difficulties as not relevant to men remain dominant.     

When Subjectivism Matters

Abstract: In this article I consider when the question of whether entities exist subjectively (only in the minds of subjects) or objectively (in themselves, independently of the minds of subjects) is important, both theoretically and practically. I argue that when it comes to the metaphysics underlying three types of moral questions, broadly conceived, the subjectivity question does not matter practically, although it is widely thought to matter. Subjectivism does not matter in these moral questions in the same way(s) it matters in some nonmoral metaphysical issues. The moral questions I consider are the meaning of life, normative ethics, and the free‐will problem. The nonmoral issues I address are the existence of God, the traditional mind/body problem, and personal identity. I explain the difference by noting that certain metaphysical issues on the fact side of the fact/value distinction impinge on persons' lives more prominently than do the metaphysics behind the three moral questions.     

Contextual and Cognitive Determinants of Procedural Justice Perceptions in Promotion Barriers for Women

The relationships between procedural justice in promotion decisions for women and contextual factors deemed as contributing to glass ceilings were examined. The contextual factors examined were a lack of female role models, limited networking opportunities for women, gender segregation, and formal career ladders. It was found that gender schema is a moderator between procedural justice and the perceived number of female role models and between procedural justice and the perception of formal career ladders. Although gender schema was not a moderator in the relationship between procedural justice and gender segregation, nor in the relationship between procedural justice and networking opportunities for women, a significant main effect was found. These results are consistent with the notion that organizational justice perceptions are products of individual cognitive processes, which develop in response to cultural expectations.     

The hijab as a protective factor for body image and disordered eating: a replication in French Muslim women

We examined differences in body image and disordered eating between Muslim women who do and do not wear the hijab in France, a nation marked by religious-based sartorial censorship. In an online survey, 450 French Muslim women completed measures of hijab use, weight discrepancy, disordered eating, body image-related constructs, religiosity, perceived support from Allah, and perceived discrimination. Controlling for religiosity and support from Allah, women who wore the hijab reported significantly lower weight discrepancy, body dissatisfaction, drive for thinness, social physique anxiety, internalisation of the thin and muscular ideals, and pressure to attain ideals from peers and the media, though they also reported significantly higher perceived discrimination than those who did not wear the hijab. Further analyses showed that use of the hijab was significantly associated with weight discrepancy and disordered eating. Our results suggest that use of the hijab may offer a protective element for French Muslim women.     

Sex differences in trauma symptoms,body image and intensity of pain in a Polish sample of patients suffering from chronic pain

The main goal of the current study was to investigate sex differences in the relationship between the level of trauma symptoms appearing in posttraumatic stress disorder (PTSD) and intensity of pain in a sample of 300 Polish patients suffering from chronic pain, specifically rheumatoid arthritis and lower back pain. We also focused on participants’ body image with body esteem as a mediator. To assess the intensity of pain among participants, we used the Numerical Rating Scale. The level of trauma symptoms was assessed with the PTSD Factorial Version Inventory. To measure body image among participants, we used the Body Esteem Scale. The results of our study suggest that trauma symptoms and body image dimensions were significant predictors of pain intensity among men suffering from chronic pain. Moreover, trauma symptoms and age were significant predictors of pain intensity among women suffering from chronic pain. Finally, we demonstrated that sex differentiates the reaction to chronic pain.
