Knowing about the properties of objects by wielding them and knowing about the distances of surfaces by striking them with objects as probes are examples of dynamic or effortful touch. Six experiments focused on the invariant mechanical parameters that couple the time-varying states (displacements, velocities) of hand-held rods to the time-varying torques and forces imposed upon them by wielding and probing. There were three major conclusions. First, when a probe is wielded without contact, perceived probe length is a function of the probe’s rotational inertia; however, with contact, perceived probe length is affected by the rotational inertia and the distance of the point of contact from the probe’s center of percussion. Second, when a surface is struck with a probe, perceived surface distance is affected by the probe’s rotational inertia and the angle of inclination of the probe at contact. Third, under seemingly identical conditions of probing, either probe length or surface distance can be perceived selectively without confusion. Results were discussed in terms of haptic information, haptic attention, and the dynamics of probing. 相似文献

This study profiles the characteristics of adolescent suicide attempters and the treatment they received in a pediatric emergency room (ER). A retrospective chart review of 4,072 adolescents seen in the ER at a children's hospital (CH) from July 1984 to June 1985 was undertaken. Twenty-seven adolescents who had deliberately injured themselves were identified. The average age was 14 years 7 months (range 11-19 years). Fifty-two percent of the patients were white and 78% were female. Ingestion was the most common method (78%), followed by attempted hanging (11%), and wrist laceration (7%). After evaluation by a pediatrician in the ER, 30% of the patients were treated and released, 11% were transferred directly to a psychiatric hospital, and 59% were admitted to the CH, with an average hospital stay of 1.88 days. Once hospitalized, consultations from psychiatry (81%), social service (50%), psychology (19%), and neurology (6%) were obtained. At the time of discharge from either the ER or CH, the patients had a variety of plans for ongoing care, with 52% being referred to outpatient counseling, 37% being transferred to a psychiatric hospital, and 11% having no documented plan for ongoing care. These results demonstrate that the evaluation of suicidal adolescents cared for in a pediatric facility may be episodic and suggest the need for a comprehensive program to approach the problem. 相似文献

This research examined the influence of mood-congruent and mood-incongruent contexts on recognizing affective prosody after brain damage. Predictions stemmed from an associative network theory of learning and memory. Thirty-three male subjects, 11 each in right hemisphere damaged (RHD), left hemisphere damaged (LHD), and normal control groups judged moods from the prosody of semantically neutral phrases. In one task, the prosodic stimulus phrases were judged in isolation. In another task, the phrases were preceded by short paragraphs which were either congruent or incongruent in emotional tone with the prosodic stimuli. These paragraphs were designed to prime specific mood choices. As anticipated, LHD subjects' prosodic mood recognition was more accurate when given congruent rather than incongruent affective contexts. Congruent contexts facilitated, and incongruent contexts disrupted, their prosodic mood judgments to the same extent as normals. RHD subjects showed a partial context decrement. They were less accurate than normal or LHD subjects in the congruent condition, and were unaffected by incongruent contexts. When given congruent biasing paragraphs, however, RHD subjects did experience facilitation on a par with that found for the other groups, indicating spared sensitivity to certain contextual factors. The distinction between automatic and effortful processes is offered as a potential explanation for the RHD group's pattern of performance. 相似文献

Marilyn Frye's first book, The Politics of Reality: Essays in Feminist Theory, presents nine philosophical lectures: four on women's subordination, four on resistance and rebellion, one on revolution. Its approach combines a lesbian perspective with analytical philosophy of language. The major contributions of the book are its analysis of oppression, highly suggestive discussions of the roles of attention in knowledge and ignorance and in arrogance and love, a defense of political separatism not based on female supremacism, and a development of the idea of lesbian epistemology. Its proposal for resisting White racism will be controversial. Its treatment of gay rights is not balanced by an acknowledgement that drag queens, like “totaled women,” are products of oppression, not simply of intolerance. The most philosophically problematic aspect of the book is its analysis of coercion and of the roles of coercion in women's subordination. This creates an unresolved tension with the positive message of the second half of the book. Despite this difficulty, these essays are an outstanding contribution to contemporary feminist theory. 相似文献

Stimulated by publicity over lawsuits involving parents of children who had died from deprivation of medical care, this article is a survey of the beliefs of religious groups that refuse medical care on theological grounds and the legal principles designed to protect children from such abuse. Particular attention is given to whether or not child-neglect laws that carve out exceptions for spiritual healing groups are constitutional under the establishment clause of the First Amendment. Very recent cases, including some still in progress, are used for illustration. 相似文献

The study investigated interactions between learner expertise and task complexity evaluated from both cognitive and affective perspectives. One hundred and seventy-three students, both novices and advanced learners, were asked to learn Japanese writing in a pen-tablet-based digital learning environment with varying task complexity levels. Cognitive load and learning-centred emotions were measured at intervals during learning, while writing performance was monitored by runtime tracking. Results indicated that while advanced learners performed better than novices across the range of task complexity, the moderate task complexity was shown to be superior in enhancing performance for both levels of expertise. Results for learning-centred emotions showed that advanced learners reported lower enjoyment and higher frustration when completing the low complexity task, whereas the moderately complex task was reported to be the most enjoyable and less frustrating for these learners. No significant difference in emotions was found across levels of task complexity for novices. Finally, a constructed composite indicator of cognitive-affective efficiency of instructional conditions showed a significant interaction between levels of learner expertise and task complexity primarily caused by affective factors. 相似文献

No previous studies have analyzed values as qualities of relational microsystems, such as the romantic couple. Based on Schwartz's Theory of Human Values, this study examines the psychometric properties of the Portrait Couple Values Questionnaire (PCVQ). It measures four couple value dimensions: conservation, openness to change, self-enhancement, and self-transcendence. Five hundred and forty-six Italian respondents (54.1% women), aged 41.52 years (SD = 7.19; range 23–63) and having a couple relationship, have filled in an anonymous online questionnaire. The results show the good psychometric properties of the PCVQ. The Confirmatory Factor Analysis Magnifying Glass Strategy shows good indexes of fit for each value dimension, except for the Root Mean Square Error of Approximation (RMSEA) for openness to change, thus confirming that the PCVQ measures the four values with satisfactory internal consistency. The Multidimensional Scaling results, by showing a Stress-1 index of 0.07, confirm the circular structure of values because the four value dimensions are in the position predicted by Schwartz's model. Participants' personal and couple values are highly but not perfectly correlated, suggesting that couple values are a related but distinct construct compared to personal values. This study's contribution lies in introducing an innovative construct into the literature on values and couples, proposing a scale to assess it. 相似文献

This report tested whether those individuals with a cluster B DSM-IIIR personality disorder (narcissistic, borderline, antisocial or histrionic) had higher scores for aesthetic preference for visually complex drawings using the Barron-Welch Art Scale. In a sample of 141 patients and controls, the 56 subjects who met the criteria for one of the cluster B personality disorder diagnoses displayed higher Barron-Welch Art Scale Scores. A multiple regression analysis showed that narcissistic and borderline personality disorder contributed positively, while dependent personality disorder, negatively to preference for complexity. The findings support the notion that aesthetic choices and values reflected through the dimension of openness to experience may contribute to the behavioral manifestations of the personality disorders. 相似文献
