Inferring the preferences of others from spontaneous, low-emotional facial expressions

The present study investigates whether people can infer the preferences of others from spontaneous facial expressions alone. We utilize a paradigm that unobtrusively records people's natural facial reactions to relatively mundane stimuli while they simultaneously report which ones they find more appealing. Videos were then presented to perceivers who attempted to infer the choices of the target individuals—thereby linking perceiver inferences to objective outcomes. Perceivers demonstrated above-chance ability to infer target preferences across four different stimulus categories: people (attractiveness), cartoons (humor), paintings (decorative appeal), and animals (cuteness). While perceivers' subjective ratings of expressivity varied somewhat between targets, these ratings did not predict the relative “readability” of the targets. The findings suggest that noncommunicative, natural facial behavior by itself suffices for certain types interpersonal prediction, even in low-emotional contexts.     

Repeated Exposure to Forward Support-Surface Perturbation During Overground Walking Alters Upper-Body Kinematics and Step Parameters

Locomotion requires both proactive and reactive control strategies to maintain balance. The current study aimed to: (i) ascertain upper body postural responses following first exposure to a forward (slip) support-surface perturbation; (ii) investigate effects of repeated perturbation exposure; (iii) establish relationships between arms and other response components (trunk; center of mass control). Young adults (N = 11) completed 14 walking trials on a robotic platform; six elicited a slip response. Kinematic analyses were focused on extrapolated center of mass position (xCoM), bilateral upper- and forearm elevation velocity, trunk angular velocity, and step parameters. Results demonstrated that postural responses evoked in the first slip exposure were the largest in magnitude (e.g., reduced backward stability, altered reactive stepping, etc.) and preceded by anticipatory anterior adjustments of xCoM. In relation to the perturbed leg, the large contra- and ipsilateral arm responses observed (in first exposure) were characteristically asymmetric and scaled to the degree of peak trunk extension. With repeated exposure, xCoM anticipatory adjustments were altered and in turn, reduced posterior xCoM motion occurred following a slip (changes plateaued at second exposure). The few components of the slip response that persisted across multiple exposures did so at a lesser magnitude (e.g., step length and arms).     

Cross‐cultural,population‐based study on adolescent body image and eating distress in Japan and Finland

This cross‐sectional population‐based survey compares the prevalence of self‐reported body image and eating distress symptoms among adolescents in Japan and Finland, and associations between emotional/behavioral problems, body image and eating distress from a cross‐cultural perspective. The study included 1,840 Japanese and 1,135 Finnish 8th grade students. The self‐reported questionnaire included the Body Image and Eating Distress Scale and Strengths and Difficulties Questionnaire (SDQ). The female adolescents from both Finland and Japan reported much greater dissatisfaction with, and concern about, their bodies than the males and Japanese females expressed even higher distress than Finnish females. High levels of body image and eating distress were associated with psychiatric problems measured with the SDQ. There was a significant three‐way interaction effect of body image and eating distress, gender and country with SDQ peer problems and prosocial behavior.     

具身模拟在汉语肢体动作动词理解中的作用

通过3个实验, 考察具身模拟在汉语肢体动作动词理解中的作用。实验1考察在整字启动下具身模拟对运动通道中箭头方向判断的影响, 发现理解肢体动作动词在运动通道中存在着动作-汉字相容效应, 汉字的具身方向与箭头方向一致促进被试对箭头方向的判断。实验2考察在整字启动下具身经验对视觉通道中字母位置判断的影响, 发现理解肢体动作动词在视觉通道中存在着动作-汉字相容效应, 汉字的具身方位与字母方位一致促进对字母方位的识别。实验3采用义符启动范式考察义符与整字的具身模拟, 发现理解汉语肢体动作动词不仅在整字层次上存在着具身模拟, 在部件层次上也存在着具身模拟。义符在汉字加工中期被激活了, 并且持续到加工晚期。整个研究表明, 汉语肢体动作动词理解是一个跨通道的具身模拟过程, 具身模拟在汉语肢体动作动词的理解中起着非常重要的作用。     

‘I didn’t realise I was such a sausage’: men’s accounts of whole-body scanning,body image,and expected changes in health-related behaviours

Objective: Whole-body scanning is now available in stores to assist buyers in choosing well-fitting clothes. This study was designed to investigate men’s accounts of scanning, body image and expectations of behaviour change. Design: Ten men aged 18–39 years without histories of eating disorders or previous experience of whole-body scanning, took part in semi-structured interviews before and after scanning. Data were analysed using inductive thematic analysis. Results: Pre-scan, men’s body ideals were tall, slender and relatively muscular. Post-scan, seven reported looking shorter, fatter, thinner and/or less symmetrical than they hoped; three were pleasantly surprised by the images. Men were interested in scans as an objective view of their bodies and as a ‘wake-up call’ to motivate healthy behaviours. Five men intended to change their behaviour as a result of scanning, and repeat scanning was seen as a good way to monitor behavioural changes. Participants suggested that scanning may raise body concerns in other men, though downplayed impacts on their own body image. Conclusion: Whole-body scanning may encourage men to exercise and eat more healthily. However, men became more negative about their bodies as a result of seeing their body scans, so scanning needs to be carried out with supervision and support.     

The dynamic and recursive interplay of embodiment and narrative identity

Although there is an increase in research into how narrative identity interrelates with embodiment, the mechanisms underlying this interplay are hardly addressed. In this paper, I target this hiatus in the literature by proposing two mechanisms that can help to (non-exhaustively) elucidate the dynamic interplay of narrative identity and embodiment. I start by briefly sketching the debate so far and then go on to argue that the way narrative self-understanding affects our embodiment can be understood on the model of narrative self-programming. After that I turn to the other side of the interaction. Drawing on research in ecological psychology and phenomenology, I show how embodiment affects our narrative self-understanding through the way in which we engage with affordances in our narrative background. After that I highlight the dynamic and recursive character of this interplay. I end with some conclusions and unresolved issues.     

DOWN TO EARTH WITH NIETZSCHE: The ethical effects of attitudes toward time and body

This paper is about the effects on people's lives of their attitudes towards time and their own embodiment. People commonly see time as biform; there is the time of bodily life and the eternal time which transcends mortal life. This division is deeply implicated in the dualistic values that pervade western thought. So, when Nietzsche substitutes a monist notion of time, he profoundly unsettles our cherished values (which, of course, are gendered). Nietzsche's major thrust, I argue, is to elucidate and advocate the more appropriate values that emerge when human existence is understood as entirely earthborn.I use two contrasting literary characters to show concretely how people's lives and relationships are affected negatively or positively according to the temporal perspectives they adopt (and thus the significance they give to their corporeality). I explain how acceptance of human finitude enables a fruitful and rewarding life, while its refusal is life-diminishing. This also makes conceivable a realm beyond gender.     

Is `Property' Necessary? On Owning the Human Body and its Parts

Courts usually treat control over human bodies and body parts as a property issue and find that people do not have property rights in themselves. This contradicts the liberal philosophical principle that people should be able to perform any self-regarding actions that do not cause harm to others. The philosophical inconsistencies under pinning the legal treatment of body parts arguably stem from a misplaced judicial preoccupation with‘property’. A better approach would be to hold a policy inquiry into the degree of liberty a society wishes to grant its inhabitants. Only once this substantive issue has been addressed should property be raised as a possible method of implementing the policy. This revised version was published online in August 2006 with corrections to the Cover Date.     

Facial expressions modulate the gaze orienting effect on sound localization judgement

Recent studies have shown that cueing eye gaze can affect the processing of visual information, and this phenomenon is called the gaze-orienting effect (visual-GOE). Emerging evidence has shown that the cueing eye gaze also affects the processing of auditory information (auditory-GOE). However, it is unclear whether the auditory-GOE is modulated by emotion. We conducted three behavioural experiments to investigate whether cueing eye gaze influenced the orientation judgement to a sound, and whether the effect was modulated by facial expressions. The current study set four facial expressions (angry, fearful, happy, and neutral), manipulated the display type of facial expressions, and changed the sequence of gaze and emotional expressions. Participants were required to judge the sound orientation after facial expressions and gaze cues. The results showed that the orientation judgement of sound was influenced by gaze direction in all three experiments, and the orientation judgement of sound was faster when the face was oriented to the target location (congruent trials) than when the face was oriented away from the target location (incongruent trials). The modulation of emotion on auditory-GOE was observed only when gaze shifted followed by facial expression (Exp3); the auditory-GOE was significantly greater for angry faces than for neutral faces. These findings indicate that auditory-GOE as a social phenomenon exists widely, and the effect was modulated by facial expression. Gaze shift before the presentation of emotion was the key influencing factor for the emotional modulation in an auditory target gaze-orienting task. Our findings suggest that the integration of facial expressions and eye gaze was context-dependent.     

Across the Martian Frontier? Thoughts on Planet B,a Martian Safety Valve,and the Earth as Our Body

Even though we are on the precipice of a “bad Anthropocene,” humankind should not colonize Mars. Mars is often depicted as our “Planet B”—an evacuation plan for Earth. But in this time of ecological crisis, theologian Sallie McFague suggests that we think of the Earth as God’s body and take our obligation to care for our common home seriously. Likewise, in contrast to calls for colonization, I contend that two American historical anecdotes—the safety valve theory and the Yellowstone—illustrate why humanity should think less about becoming Martians and instead find meaning and purpose in remaining Earthlings.
