Background: With the ever-increasing political, ideological and social tension which followed 9/11, crime prevention stands as an issue of major relevance. The development of the ability to accurately detect statements of false intent is of great societal and legal value. It could aid intelligence services in preventing crimes (e.g., terrorist threats) and security services in reinforcing their protocols (e.g., airport security checks, parole hearings, and border control).Goals: To examine the associations between hand movements and false intentions in adults.Methods: Using a laboratory-based variation of the ‘Portsmouth design’, 23 students completed a questionnaire about their intentions to travel in the near future. Participants with a planned trip were placed in the truth tellers’ condition (n = 12). Those who did not have a planned trip were placed in the liars’ condition (n = 11). Based on the main theoretical approaches, three hypotheses were proposed. Hypothesis 1 advocated a decrease in the three categories of illustrators (movements interconnected to speech that serve to illustrate what is being verbally said) in liars, as compared to the truth tellers. Hypothesis 2 also suggested a decrease in the category of subtle hand and finger movements in the lying condition, comparatively with the truth condition. Finally, hypothesis 3 proposed a lack of significant differences between liars and truth-tellers in the five categories of self-adaptors (movements in which one part of the body does something to another body part, such as scratching the ear or squeezing the hands).Results: Hypothesis 1 was partially supported. The general and the unilateral categories of illustrators decreased in the case of the liars, as compared to the truth tellers; however, the bilateral category of illustrators slightly increased in the lying condition, in comparison with truth telling. Hypotheses 2 and 3 were fully supported. Discussion: Apart from the slight increase of bilateral illustrators in the case of the liars, all the results are in accordance with the empirical findings on deception research about past events. This similarity is noteworthy, considering the cognitive differences between lies about past events and lies about future events.

Young children asked to make hand movements which cross the body are likely to respond with a movement confined to the same body side as the hand used. This crosslateral inhibition effect (CIE) features in Kephart's (1971) perceptualmotor theory; there is an extensive, earlier, literature on CIE in adults following cerebral insult; since the twenties, attempts have been made to relate developmental, clinical and neuropathological findings. In the present study 120 children aged from 3 to 8 years faced and copied hand movements of a model in a procedure following Head's (1920) Hand, Eye and Ear Test. CIE was confirmed, but differences between groups did not convincingly relate to age. CIE was greatest not at 3, 4 or 5 but at 6 years; further, 4-year-olds subjects made more preferred hand crosslateral responses than any other group. Analysis of imitation performance showed that older subjects applied a “proximity” strategy to both body part touched and hand use, whereas younger subjects disregarded the latter. It is argued that developmental CIE stems from procedural constraints and an agerelated choice of response strategy, and not learning related to a lateral bifurcation of perceptual-motor organization.

AbstractBody ownership concerns what it is like to feel a body part or a full body as mine, and has become a prominent area of study. We propose that there is a closely related type of bodily self-consciousness largely neglected by researchers—experiential ownership. It refers to the sense that I am the one who is having a conscious experience. Are body ownership and experiential ownership actually the same phenomenon or are they genuinely different? In our experiments, the participant watched a rubber hand or someone else’s body from the first-person perspective and was touched either synchronously or asynchronously. The main findings: (1) The sense of body ownership was hindered in the asynchronous conditions of both the body-part and the full-body experiments. However, a strong sense of experiential ownership was observed in those conditions. (2) We found the opposite when the participants’ responses were measured after tactile stimulations had ceased for 5 s. In the synchronous conditions of another set of body-part and full-body experiments, only experiential ownership was blocked but not body ownership. These results demonstrate for the first time the double dissociation between body ownership and experiential ownership. Experiential ownership is indeed a distinct type of bodily self-consciousness.

The Impact

The objective of this case study was to experimentally manipulate the impact on arousal and recall of two characteristics frequently occurring in gruesome depictions of body parts in smoking cessation advertisements: the presence or absence of an external physical insult to the body part depicted; whether or not the image contains a clear figure/ground demarcation. Three hundred participants (46% male, 54% female; mean age 27.3 years, SD = 11.4) participated in a two-stage online study wherein they viewed and responded to a series of gruesome 4-s video images. Seventy-two video clips were created to provide a sample of images across the two conditions: physical insult versus no insult and clear figure/ground demarcation versus merged or no clear figure/ground demarcation. In stage one, participants viewed a randomly ordered series of 36 video clips and rated how “confronting” they considered each to be. Seven days later (stage two), to test recall of each video image, participants viewed all 72 clips and were asked to identify those they had seen previously. Images containing a physical insult were consistently rated more confronting and were remembered more accurately than images with no physical insult. Images with a clear figure/ground demarcation were rated as no more confronting but were consistently recalled with greater accuracy than those with unclear figure/ground demarcation. Makers of gruesome health warning television advertisements should incorporate some form of physical insult and use a clear figure/ground demarcation to maximize image recall and subsequent potential advertising effectiveness.

Body Image Disturbances

Despite much recent interest in the objective measurement of body image in anorexia nervosa, many questions remain regarding basic mechanisms responsible for the findings as well as their meaning in the disorder. It is unclear if “whole body” measures assess the same underlying phenomena as the “body part” method, and it is unclear if body image disturbances are etiologic or a byproduct of anorexia nervosa. The possible association between self-esteem and body satisfaction and the relationship of the latter variable to actual size estimation supports the hypothesis that size perception may be closely tied to satisfaction with non-physical aspects of self. Finally it must be determined if over estimation is a function of a general psychological disturbance or of a deficit of specific interest in this disorder. Despite these questions, the way in which anorexic patients see themselves as well as the cognitive and affective responses to this perception remains an interesting and potentially fruitful area of study with this disorder.

Health Eating

Employing a variety of theoretical approaches, feminist researchers have critiqued the fitness industry of its singular emphasis on the impossible, narrowly defined feminine body ideal that is likely to cause more mental (e.g., body dissatisfaction) and physical ill health (eating disorders, injuries) than improve fitness. With the focus on social construction of gendered identities, there has been less problematisation of the materiality of the fitness practices and their impact on the cultural production of the moving body. In this article, I adopt a Latourian approach to seek for a more complete account of the body in motion and how it matters in the contemporary world. A barre class as a popular group exercise class that combines ballet and exercise modalities offers a location for such an examination due to the centrality of a non-human object, the barre, that distinguishes it from other group exercise classes. I consider how exercise practices may be constituted in relation to a material object, the barre, and how the physical and material intersect, historically, with the cultural politics of fitness and dance from where the barre originates. To do this, I trace the journey of the barre from ballet training to the fitness industry to illustrate how human and non-human associations create a hybrid collective.

Epilepsia partialis continua manifests as low-frequency, rhythmic involuntary movements of a focal body part. We report a young man, HIV-positive and with syphilis, who developed right-hand epilepsia partialis continua associated with a small left-sided cortico-subcortical frontal lesion. A pen and paper test provided ‘mechanographic’ data on frequency, amplitude and rhythmicity of the hand movements, helping distinguish it from other causes of low-frequency repetitive hand movements.

The article presents the analysis of the onomasiological structure of the metaphorical somatonyms of Northern Samogitians, focusing on the indicators of the source of metaphors. Based on the explicit semantics of the source (lexical motivators), the metaphorical somatonyms of Northern Samogitians belong to several motivational models, the most productive of which is the artefactual motivational model. The basis of the artefactual metaphor is the associative similarity of the object (artefact) and the body part according to various parameters – shape, size, features of structure and materiality, actions, especially repetitive movements.

Introduction: Protracted physical exertion leads to the development of fatigue. The development of fatigue has previously been associated with increased effort costs, influencing decisions to engage in further physical activity. However, whether fatigue-associated changes to effort-based decisions are reflective of a global aversion to effort in response to fatiguing physical exertion, affecting the decision to engage in physical action performed in other parts of the body, is unclear. Methods: To investigate this, we tested whether effort-based choice behaviour was altered by fatigue, pre-induced through physical exertion of a different body part. Twenty-two healthy male participants made a series of choices between two rewarded actions, which varied in both the level of effort required (relative duration of a submaximal contraction of the dominant knee extensors) and reward obtained (monetary incentives). Participants made their choice under two conditions: 1) a pre-induced state of fatigue and 2) a rested (control) state. Results: Across conditions, participants’ choice behaviour demonstrated the anticipated aversion to effort that interacted with the level of reward on offer. However, though prior physical exertion increased the perception of fatigue, prolonged choice selection-time and reduced self-reported confidence in ability to perform chosen effort-demanding actions, participants choice behaviour did not significantly differ between the two conditions. Conclusions:. The findings suggest that a subjective state of fatigue does not increase the general cost of exerting effort across the body but does increase uncertainty within decision-making processes which may alter evaluative processes that precede changes in cost/benefit computations.
