Individual differences in the rubber-hand illusion: Predicting self-reports of people's personal experiences

Can we assess individual differences in the extent to which a person perceives the rubber-hand illusion on the basis of self-reported experiences? In this research, we develop such an instrument using Rasch-type models. In our conception, incorporating an object (e.g., a rubber hand) into one's body image requires various sensorimotor and cognitive processes. The extent to which people can meet these requirements thus determines how intensely people experience and, simultaneously, describe the illusion. As a consequence, individual differences in people's susceptibility to the rubber-hand illusion can be determined by inspecting reports of their personal experiences. The proposed model turned out to be functional in its capability to predict self-reports of people's experiences and to reliably assess individual differences in susceptibility to the illusion. Regarding validity, we found a small, but significant, correlation between individual susceptibility and proprioceptive drift. Additionally, we found that asynchrony, and tapping rather than stroking the fingers constrain the experience of the illusion.     

我们应该“创造生命”吗？

人造细胞是现代生物科学技术中的热点问题之一,由人造细胞及其衍生出来人造生命的伦理问题也备受关注,关于是否应该继续研究人造生命,支持者和反对者之间各执其词。以克莱格·文特“创造人造细胞”事件为切入点,回顾了人造生命的历史,简要介绍人造细胞的产生过程,分析人造细胞的正面和负面影响;同时提出马克思主义哲学可以为医学伦理问题的研究提供不同的维度与角度,让人们对人造细胞产生的道德问题做出更全面的判断。     

Capturing Children's Response to Parental Conflict and Making Use of It

To read this article's abstract in both Spanish and Mandarin Chinese, please visit the article's full-text page on Wiley InterScience ( http://interscience.wiley.com/journal/famp ).
The aim of our study is to examine the interface between children's physiological changes and the specificities of parental conflict, and to develop a procedure in which such information can be shared with the family for therapeutic change. Children from 20 families were exposed to parental conflict discussion (CD) while their arousals were measured through skin conductance and heart rate sensors. It was found that regardless of the subject of the argument, 80% of the time they were complaining about each other. Likewise, 80% of the time the children were responding to the parents' own interpersonal tension, including moments of silence. The protocol established for the study, consisting of CD and debriefing, was found to be a powerful tool in moving parents toward conflict resolution.

The impact of violations on uncertainty and the consequences for attractiveness

This investigation aimed at extending past research on expectation violations by arguing that violations vary both in valance and in their influence on uncertainty and that the combination of valence and uncertainty states conjointly influences judgments of a violator's social attractiveness. In explaining the predicted variance in uncertainty following violations, a distinction is proposed between congruent violations (i.e., behaviors that are more intense instantiations of a previously displayed message) and incongruent violations (i.e., behaviors that are opposite in meaning from previously displayed messages). Five models for explaining violation effects are contrasted. Results (a) confirm that violations differ in their impact on uncertainty, (b) generally support the validity of the proposed distinction between congruent and incongruent violations, and show that the inclusion of uncertainty and valence in models of violation outcomes accounts for greater variance in social attraction than either one separately.     

Reality check: the role of realism in stress reduction using media technology.

There is a growing interest in the use of virtual and other mediated environments for therapeutic purposes. However, in the domain of restorative environments, virtual reality (VR) technology has hardly been used. Here the tendency has been to use mediated real environments, striving for maximum visual realism. This use of photographic material is mainly based on research in aesthetics judgments that has demonstrated the validity of this type of simulations as representations of real environments. Thus, restoration therapy is developing under the untested assumption that photorealistic images have the optimal level of realism, while in therapeutic applications 'experiential realism' seems to be the key rather than visual realism. The present paper discusses this contrast and briefly describes data of three studies aimed at exploring the importance and meaning of realism in the context of restorative environments.     

The effect of similarities in skin texture and hand shape on perceived ownership of a fake limb

In the rubber-hand illusion (RHI), people attribute an artificial object to their own body. In the present study, we investigate the extent to which RHI is affected by visual discrepancies between the artificial object and a human hand. We tested Armel and Ramachandran's (2003) hypothesis that people will experience a stronger RHI when the artificial object is a skin-like textured sheet instead of a tabletop. We did not find support for their hypothesis, but the strength of the RHI diminished when the texture of a hand-shaped object did not resemble the human skin (manipulated by putting a white glove over the cosmetic prosthesis). We provide an alternative explanation for this finding, based on a skill-based sensorimotor account of perceived body ownership. Such an explanation supports Armel and Ramachandran's more general claim that discrepancies in the nature of expected and felt touch diminish the RHI.
