The purpose of these experiments was to determine the effects of object weight and condition of weight presentation on the kinematics of human prehension. Subjects performed reaching and grasping movements to metal dowels whose visible characteristics were similar but whose weight varied (20, 55, 150, 410 g). Movements were performed under two conditions of weight presentation, random (weight unknown) and blocked (weight known). Three-dimensional movements of the thumb, index finger, and wrist were recorded, using a WATSMART system to obtain information regarding the grasp and transport components. The results of the first experiment indicated that object weight and condition of presentation affected the temporal and kinematic measures for both the grasp and transport components. In conjunction with the results of a second experiment, in which time in contact with the dowel was measured, it was shown that the free-motion phase of prehension (i.e., up to object contact) was invariant over the different conditions, however. The changes were observed in the finger-object interaction phase (when subjects applied forces after contact with the dowel), prior to lift-off. These results were interpreted as indicating (a) object weight does not influence the planning and execution of the free-motion phase of prehension and (b) there are at least two motor control phases involved in prehension, one for making contact with the object and the other for finger-object interaction. The changing contributions of visual, kinesthetic, and haptic information during these two phases is discussed. 相似文献

This study examined psychologists' views and practices regarding diagnostic classification systems for mental and behavioral disorders so as to inform the development of the ICD‐11 by the World Health Organization (WHO). WHO and the International Union of Psychological Science (IUPsyS) conducted a multilingual survey of 2155 psychologists from 23 countries, recruited through their national psychological associations. Sixty percent of global psychologists routinely used a formal classification system, with ICD‐10 used most frequently by 51% and DSM‐IV by 44%. Psychologists viewed informing treatment decisions and facilitating communication as the most important purposes of classification, and preferred flexible diagnostic guidelines to strict criteria. Clinicians favorably evaluated most diagnostic categories, but identified a number of problematic diagnoses. Substantial percentages reported problems with crosscultural applicability and cultural bias, especially among psychologists outside the USA and Europe. Findings underscore the priority of clinical utility and professional and cultural differences in international psychology. Implications for ICD‐11 development and dissemination are discussed. 相似文献

Two studies done from constructivist perspectives were considered for their complementarity in understanding the development of gifted young artists. Study 1 used Case's (1992) neo-Piagetian theory as a framework and investigated the developmental progression in ability to represent spatial relations in children aged 4,6,8, and I0 years. Children identified as gifted demonstrated some advancement in their use of perspective but were distinguished primarily by their elaborate and novel representations of space. An age-related progression in acquisition of ability to render perspective supports a general factor in development, whereas abilities unique to the artistic domain support the relevance of including domain-specific characteristics in developmental models of giftedness. Study 2 was done primarily from a structuralist perspective but also incorporated a postformal perspective on the problem-finding and problem-solving behaviors of young artists aged I3 to 18 years. There was support for age-related domain-general aspects of thought with discipline-specific skills in making multiple comparisons in proportional relations and coordinating multiple perspectives. This finding may be an extension of young children's intrastage elaboration of the spatial structures available to them. 相似文献

Three studies examined whether strategy utilization deficiencies emerge during transfer to two tasks that differ superficially from the main task but have the same underlying structural logic. In Experiment 1, children aged 4, 4½, and 5 spontaneously produced selective attention strategies (or were prompted to do so) on a selective memory task. Although children of all ages transferred this strategy, recall declined on the transfer tasks, a pattern indicating a “transfer utilization deficiency.” This pattern appeared whether children were initially strategic or became strategic after prompts. Individual and trial-by-trial analyses showed asynchronies between changes in strategic behavior and recall (e.g., increased strategy production but decreased recall), which indicate a utilization deficiency. Experiment 2 demonstrated this pattern in spontaneously strategic 4-year-olds, and, by systematically varying task order, eliminated the possibility that transfer tasks were simply more difficult. Experiment 3 eliminated the role of boredom or fatigue for spontaneously strategic 4- and 5-year-olds. Transfer tasks may generate uncertainty about whether and how to apply a strategy, leading to resource-demanding self-monitoring and thus utilization deficiencies. 相似文献

A range of negative health outcomes are associated with young adults’ drinking practices. One key arena where images of, and interaction about, drinking practices occurs is social networking sites, particularly Facebook. This study investigated the ways in which young adults’ talked about and understood their uses of Facebook within their drinking practices. Face-to-face, semi-structured interviews were conducted with seven New Zealand young adults as they displayed, navigated and talked about their Facebook pages and drinking behaviours. Our social constructionist thematic analysis identified three major themes, namely ‘friendship group belonging’, ‘balanced self-display’ and ‘absences in positive photos’. Drinking photos reinforced friendship group relationships but time and effort was required to limit drunken photo displays to maintain an overall attractive online identity. Positive photos prompted discussion of negative drinking events which were not explicitly represented. Together these understandings of drinking photos function to delimit socially appropriate online drinking displays, effectively ‘airbrushing’ these visual depictions of young adults’ drinking as always pleasurable and without negative consequences. We consider the implications of these findings for ways alcohol health initiatives may intervene to reframe ‘airbrushed’ drinking representations on Facebook and provoke a deeper awareness among young people of drinking practices and their online displays. 相似文献

Abstract Too often the human services dehumanize and depersonalize those who come to receive services, as well as those professionals who provide physical disabilities and people with psychiatric disabilities are frequently hurt by helping professionals, the phenomenon of “spirit breaking” is introduced. Suggestions for re‐humanizing the human services are made, including new models for clinical interaction that serve to empower rather than disempower service recipients, and the contributions that people with disabilities are making in their own state and national movements for social justice and the right to humane treatment and rehabilitation services. 相似文献

Few studies have examined whether certain coping behaviors are associated with physical outcomes following surgery. This prospective, longitudinal study investigated the effect of active and avoidant coping behaviors on two physical outcomes over time, pain and knee function, in a group of patients experiencing knee arthroscopic surgery (n = 81). Structured interviews and physician clinical assessments were conducted preoperatively and at 3 and 24 weeks postoperatively. Coping behavior was assessed during the preoperative interview, and patients were divided into high and low avoidant and active coping groups. Using repeated measures MANCOVA/ANCOVA, avoidant coping was significantly associated with knee pain and active coping was associated with knee function. Serum cortisol levels were available for a patient subset (n = 16); higher cortisol was related to both avoidant coping and poorer functioning during early recovery. Results suggest that these divergent coping behaviors are differentially associated with stress reactivity and physical outcomes in healthy patients undergoing minor knee surgery. 相似文献

Sentence completion scores for dependency, anxiety, and hostility were correlated with sentence completion measures of good flying attitude and omissions for 300 male airline pilot candidates. The scoring-by-example method used with the first three variables was highly reliable and avoided scoring overlap. All sentence completion scores were also correlated with 15 traditional measures of pilot qualification such as mechanical information and signal reaction time. While the proficiency measures were generally unrelated to the projective measures, a good attitude towards flying was positively associated with coping (not omitting sentence completion items) and the extreme suppression of anxiety and hostility under stress. Civilian airline pilots appear similar to military pilots in their exaggerated display of good adjustment. 相似文献

The newly developed Dissoziations-Spannungs-Skala (Dissociation Tension Scale; DSS) is a self-rating instrument for the assessment of psychological and somatoform dissociative features (ranging from normal up to pathological) as well as aversive inner tension occurring within the past 7 days. The DSS contains 21 items assessing dissociative symptoms and 1 additional item assessing aversive inner tension. Ratings are made on a time-oriented scale ranging from 0% (never) to 100% (constantly). We measured the psychometric qualities of the DSS in a total of 294 patients and healthy controls. Internal consistency of the DSS was high (Cronbach's α = .92; Gutmann's split-half r = .92). We found good support for convergent, discriminant, and differential validity. There was clear evidence for the DSS being a sensitive instrument for the assessment of changing symptomatology. Assessment of dissociation and other psychopathological features over the same period of time are now possible. 相似文献
