The process of describing an object's location relative to another object results in ambiguity. How do people handle this ambiguity? The present studies examined spatial language processing when use of different reference frames results in ambiguity. We investigated whether electrophysiological (ERP) measures of cognitive processing may elucidate underlying reference frame processing; in particular, we were interested in semantic integration. ERP results showed a larger N400, peaking between 300 and 375 ms, when the intrinsic frame was not used. Behavioural results mirrored this finding, indicating a reduced cognitive processing requirement for the intrinsic reference frame. Previous work has not definitively tied spatial reference frame processing to specific ERP components and their associated cognitive processes. Although the N400 peak seen in this data is early, additional work supports the N400 interpretation, thereby linking spatial frame processing to semantic integration. Results are discussed within the larger context of spatial reference frame processing. 相似文献

Institutional ethics committees (lECs) in health care facilities now create moral policy, provide moral education, and consult with physicians and other health care workers. After sketching reasons for the development of IECs, this paper first examines the predominant moral standards it is often assumed lECs are now using, these standards being neo-Kantian principles of justice and utilitarian principles of the greatest good. Then, it is argued that a feminine ethics of care, as posited by Carol Gilligan and Nel Noddings, is an unacknowledged basis for /EC discussions and decisions. Further, it is suggested that feminine ethics of care can and should provide underlying theoretical tools and standards for lECs. 相似文献

Major behavioral features of Rett syndrome are the loss of instrumental reaching and grasping and the presentation of some variant of hand-hand or hand-mouth stereotypy. As part of an experimental home intervention program, a 3-year-old girl with Rett syndrome was exposed to four types of contingency games designed to elicit instrumental reaching, kicking, vocalization, and eye movement, respectively. Parent and subject performance were videorecorded on seven occasions over the initial 2-month period. Evaluation of these records provided evidence of contingency learning in all but the vocalization games. Stereotypic hand clasping was examined in relation to the performance of instrumental behavior (reaching, kicking, looking). Coincidental (short-term mutual inhibition arising by chance co-occurrence), associative (short-term mutual inhibition arising by having elicitor in common), and foundational (long-term mutual inhibition arising by having neural network in common) forms of specific behavioral competition were defined and examined. Evidence for coincidental and foundational competition was found in the relation between reaching and hand clasping. Implications for the support of functional hand use are discussed. 相似文献

In order to assess the hypotheses that Alzheimer′s disease (AD) results in a property level restructuring, loss, or degradation of lexical-semantic knowledge, Alzheimer′s patients and normal elderly subjects were presented with a property verification task in which they were asked to judge the truth value of telegraphic statements which paired objects with their properties (e.g., "Apple is red"). Objects with either high- or low-typical exemplars of categories (e.g., "oak" is a high typical exemplar of the category "tree," while "palm" is a less typical item). Properties were varied with respect to normatively determined dominance (e.g, "fins" is a high dominant property of "trout," while "slimy" is a less dominant property) and whether they were distinctive (i.e., served to distinguish between subsets of exemplars within a category) or shared among most or all category members (e.g., "stem" for the category "fruit"). Analyses of accuracy and reaction time data suggested that AD results in neither a loss per se of representation of properties, nor a reorganization of relations between objects′ properties. However, results were consistent with a property level degradation of AD patients′ object concepts. While there was no evidence for a differential degradation of distinctive vs shared properties, results suggested that AD patients have degraded representations of lower dominant properties and properties of low-typical category exemplars. 相似文献

Strong empirical evidence was obtained in support of the proposition that nonabsolute/relativistic (N/R) thinking is a unifying commonality underlying four postformal models of higher-order thinking, namely, problem finding, dialectical reasoning, relativistic operations, and reflective judgment. Within the construct of N/R thinking, two dimensions—the basic form and the epistemic view—and two levels—the formal form and the postformal form—were differentiated as hypothesized. The findings clarify logical relationships among the models as well as provide a common link unifying their diversity. Implications and suggestions for future research are provided. 相似文献

This study was part of an ongoing investigation into four of the potential challenges confronting women and men in cross-sex fiendships (O’Meara, 1989). Unlike previous research, which explored the perspective of only one member of each cross-sex fnendship, this study examined the perspectives of both individuals in cross-sex fienhhips. The levels of actual and perceived agreement and understanding were investigated through utilization of a variation of Heiderian Balance Theory and Laing’s Interpersonal Perception Method. Seventy three pairs of cross-sex fiends completed a survey examining direct perspectives, metaperspectives, and meta-metaperspectives, on the four challenges. Over 92% of the participants were heterosexual, 68% were Caucasian, 10% were Afican American, 10% were Hispanic, 3% were Asian, 4% were Native American, and 5% indicated “other.” Results indicate that cross-sex fiends generally agree that O’Meara’s four challenges present only minimal problems in their individual relationships, and that balance theory provides a viable explanation of how perceived agreement and understanding concerning challenges are arrived at within cross-sex fnendships. Additionally, results illustrating disagreements and misunderstandings within cross-sex friendships highlight the importance of looking at the perspectives of both individuals within a dyad. 相似文献

A heterogeneous sample of adult women and men responded to a Photo Choice Task (PCT) in which they were asked to make 24 choices between two persons for a hypothetical interaction; eight of the choices were between a woman and a man. Participants also responded to a measure of adherence to Sex Role Stereotypes and to a measure of Adversarial Sexual Beliefs. On the eight choices between a woman and a man on the PCT, men over 30 and younger than 30 chose women below chance level. Women over 30 made other-gender and same-gender choices that did not differ from chance, but the women under 30 chose women over men reliably more than chance. Small but significant positive correlations were found among the scores on the PCT and the belief measures; for the total sample, the greater the choice of men over women for hypothetical interactions, the greater the agreement with sex role stereotypes and with adversarial sexual beliefs. An examination of mean differences in belief scores among groups of persons whose PCT scores (choice of men over women) were low, medium, and high revealed that men who were more likely to turn away from women in hypothetical situations were also more likely to adhere to stereotyped beliefs about sex roles and to view relationships between women and men as adversarial. This same pattern of individual differences was found among women but, for women, only the relationship between PCT scores and sex role stereotyping was significant. 相似文献
