Tactile perception depends on the contributions of four psychophysical tactile channels mediated by four corresponding receptor systems. The sensitivity of the tactile channels is determined by detection thresholds that vary as a function of the stimulus frequency. It has been widely reported that tactile thresholds increase (i.e., sensitivity decreases) as a function of age. However, there is controversial evidence with regard to the progressive loss of sensitivity starting from childhood. In this study, the tactile thresholds of children (n=9, ages 7-11 years) were measured and compared with the thresholds of young adults (n=11, ages 21-27 years). The stimuli consisted of sinusoidal bursts of mechanical displacements, which were applied to the left index fingertips of the participants by using a cylindrical probe (base area=0.126 cm2) without a contactor surround. Absolute thresholds were measured at frequencies of 2, 10, 40, 100, 250, and 500 Hz without masking. The absolute thresholds decreased at high frequencies and were similar to data from the literature except for some discrepancy because of methodological differences. In addition, the threshold of the non-Pacinian I channel was measured at 40 Hz by elevating the thresholds of the Pacinian channel by forward masking. The effects of forward masking in children were similar to results in young adults. In conclusion, there were no significant differences between the tactile thresholds of children and those of young adults at key frequencies: 40 Hz for the Pacinian and non-Pacinian I channels and 250 Hz for the Pacinian channel. These findings contradict the hypothesis that there is gradual loss of tactile sensitivity starting from childhood to early adulthood. The loss of sensitivity due to aging probably is more abrupt and occurs at a later age. 相似文献

The authors report the results of two studies in which they explored the relationship of related and individuated self-construals, as suggested by the balanced integration-differentiation (BID) model (E. O. Imamo?lu, 2003), with (a) general attachment security in the first study (N = 168 Turkish university students) and (b) relationship-specific attachment security with the family, peers, and romantic partners in the second study (N = 110 Turkish university students). Results indicated that attachment security tended to be associated with the relational self-orientation; however, when relatedness was complemented with individuation, there was a trend toward enhanced attachment security that reached significance when multiple measures of attachment across relationship contexts were considered. The authors discuss results with reference to their implications for attachment theory and the BID model. 相似文献

The aim of this study was to investigate the dynamic nature of the cortical visuospatial attention processes during the line bisection test, which is sensitive to perceptual asymmetries. EEGs of 26 normal volunteers were recorded during the administration of a computerized line bisection test, which requires participants mark the midline of lines using a mouse. Two event-related potentials subsequent and time locked to the line presentations, namely, P300 and a positive slow wave, were obtained. Findings suggested that both potentials were related to the test performance, and the right hemisphere was more active. Analysis suggested a right parietotemporal and superior parietal locus for the P300 and right prefrontal activity for the positive slow wave. A dynamic asymmetrical activity was identified, such that after primary visual perception, spatial processing is then initiated in the right parietotemporal cortex and then proceeds to the right prefrontal cortex. 相似文献

So far, women’s involvement in honor killings has been attempted to explain with the emphasis on either patriarchy or the concept of hegemonic masculinity. However, the current conceptualization of women involved in honor killings is not completely representative of all of the cases. The accurate portrayal of women’s involvement in such killings requires a broader understanding of particular circumstances of the female perpetrators, the whole dynamic behind honor killings, and of the particular relationship between victim and the perpetrator. Through reflecting on the narratives of five female perpetrators, this article aims to provide this missing focus. 相似文献

Two experiments were conducted among Turkish students to explore the effects of team or personally oriented expressions of pride or shame for joint success or failure on evaluations of the outcome, team, and partner; causal attributions were also explored. In the second experiment, complying with a partner's choice of task and influencing the preference for future partners under high or low pressure were examined. Results indicated that for success outcomes, team expressions (relative to personal ones) caused more favorable evaluations of the outcome, team harmony, and the partner, and more causal attributions to the team as a unit. Nonsignificant but consistent opposite tendencies were observed for failure outcomes. The results of the second experiment further indicated that low pressure was more effective than high in increasing preference for personally oriented partners and was marginally effective in increasing agreement for future tasks under the personal expression condition. 相似文献

This contribution examines the emotional engagement of men and women when reading narrative texts, aiming to see under which textual conditions men and women turn out to be different from or similar to each other in what they think and feel during reception. As part of an experimental mixed-methods study, male and female readers are asked to read either experience-type texts (focusing on inner experiences of characters) or action-type texts (focusing on actions as part of a suspenseful plot) and report their engagement on questionnaire scales and in written protocols. Results show that men and women differ in their engagement when reading action texts and in their emotional affinity to plots. They are highly similar when reading the experience texts, however, and in their affinity to characters. This study underlines that the emotional responses of males and females during reading are highly dependent on (con)textual cues. 相似文献

Most approaches to iterated belief revision are accompanied by some motivation for the use of the proposed revision operator (or family of operators), and typically
encode enough information in the epistemic state of an agent for uniquely determining one-step revision. But in those approaches describing a family of operators there is usually little indication of how to proceed uniquely after the first revision step. In this paper we
contribute towards addressing that deficiency by providing a formal framework which goes beyond the first revision step in
two ways. First, the framework is obtained by enriching the epistemic state of an agent starting from the following intuitive
idea: we associate to each world x two abstract objects x
+ and x
−, and we assume that, in addition to preferences over the set of worlds, we are given preferences over this set of objects
as well. The latter can be considered as meta-information encoded in the epistemic state which enables us to go beyond the
first revision step of the revision operator being applied, and to obtain a unique set of preferences over worlds. We then
extend this framework to consider, not only the revision of preferences over worlds, but also the revision of this extended
structure itself. We look at some desirable properties for revising the structure and prove the consistency of these properties
by giving a concrete operator satisfying all of them. Perhaps more importantly, we show that this framework has strong connections
with two other types of constructions in related areas. Firstly, it can be seen as a special case of preference aggregation which opens up the possibility of extending the framework presented here into a full-fledged framework for preference aggregation
and social choice theory. Secondly, it is related to existing work on the use of interval orderings in a number of different contexts. 相似文献
