We evaluated the relationship between motor and neuropsychological deficits in subjects affected by amnestic Mild Cognitive Impairment (aMCI) and early Alzheimer's Disease (AD). Kinematics of goal-directed movement of aMCI and AD subjects were compared to those of age-matched control subjects. AD showed a slowing down of motor performance compared to aMCI and controls. No relationships were found between motor and cognitive performances in both AD and aMCI. Our results suggest that the different motor behaviour between AD and aMCI cannot be related to memory deficits, probably reflecting the initial degeneration of parietal-frontal circuits for movement planning. The onset of motor dysfunction in early AD could represent the transition from aMCI to AD. 相似文献

To assess use of imagery intervention in performance of two tennis motor skills the quasi-experimental design included a pre- and posttest and a control group. The tennis service shot and service receiving skill were selected as representative of open and closed skills, respectively. 48 subjects, male tennis players, whose ages ranged from 16 to 18 yr. (M = 17.2), were divided into two groups: (1) Technical practice only which was used as control group and (2) Imagery group who received both imagery and technical practice. Analysis of covariance showed a significant main effect for the imagery intervention on the closed skill (p = .002). Findings suggest that imaging a positive outcome may be more powerful in improving performance of closed skill movements than of open skill movements. 相似文献

Although the sunk-cost effect is a well-documented psychological phenomenon in monetary investments, existing literature investigating behavioral investments (e.g., time, effort) has not replicated this effect except when such investments relate to monetary values. The current explanation for this discrepancy proposes that purely behavioral sunk-cost effects are unlikely to be observed because they are difficult to book, track, and balance in a mental account. Conversely, we argue that, through an effort-justification mechanism, people account for the amount of behavioral resources invested when selecting an alternative, in which case they may fall prey to purely behavioral sunk-cost effects. The results of two experiments support this prediction. Because many decisions involve behavioral investments, behavioral sunk-cost effects should be pervasive psychological phenomena. 相似文献

In this article we strive to provide a detailed and principled analysis of the role of beliefs in goal processing—that is,
the cognitive transition that leads from a mere desire to a proper intention. The resulting model of belief-based goal processing has also relevant consequences for the analysis of intentions, and constitutes the necessary core of a constructive theory of intentions, i.e. a framework that not only analyzes what an intention is, but also explains how it becomes what it is. We discuss similarities
and differences between our approach and other standard accounts of intention, in particular Bratman’s planning theory. The
aim here is to question and refine the conceptual foundations of many theories of intentional action: as a consequence, although
our analysis is not formal in itself, it is ultimately meant to have deep consequences for formal models of intentional agency. 相似文献

Interest in the phenomenon of workplace violence has increased in recent years because such violence is evident in the healthcare sector. The prevalence and consequences of victimization among healthcare professionals have been well-investigated but not in volunteers who have direct and prolonged contact with patients and visitors. The aim of this study was to investigate the prevalence of physical and psychological workplace violence, the psychological and emotional consequences for hospital staff and volunteers, and the coping strategies that they adopted. In the current study, both of these groups worked with patients suffering from chronic diseases in a hospital in northern Italy. The participants included 108 hospital staff and 96 volunteers in cardiology and oncology units. The results revealed that for the staff victims of physical or psychological violence, the increase in depressive and anxiety symptoms (both state and trait) corresponded to a greater use of coping strategies to avoid facing the event. For the volunteer victims of physical violence, an increase in state anxiety was associated with an attempt to cope with the discharge of emotion, whereas trait anxiety was associated with a coping strategy that represents a positive interpretation of life events. A worrisome finding was the number of staff and volunteer victims of physical and psychological violence who did not report these occurrences: only one third of staff and volunteers reported these events to management or to the police. 相似文献

Several studies have demonstrated that the processing of visuospatial memory for locations in reaching space and in navigational space is supported by independent systems, and that the coding of visuospatial information depends on the modality of the presentation (i.e., sequential or simultaneous). However, these lines of evidence and the most common neuropsychological tests used by clinicians to investigate visuospatial memory have several limitations (e.g., they are unable to analyze all the subcomponents of this function and are not directly comparable). Therefore, we developed a new battery of tests that is able to investigate these subcomponents. We recruited 71 healthy subjects who underwent sequential and simultaneous navigational tests by using an innovative sensorized platform, as well as comparable paper tests to evaluate the same components in reaching space (Exp. 1). Consistent with the literature, the principal-component method of analysis used in this study demonstrated the presence of distinct memory for sequences in different portions of space, but no distinction was found for simultaneous presentation, suggesting that different modalities of eye gaze exploration are used when subjects have to perform different types of tasks. For this purpose, an infrared Tobii Eye-Tracking X50 system was used in both spatial conditions (Exp. 2), showing that a clear effect of the presentation modality was due to the specific strategy used by subjects to explore the stimuli in space. Given these findings, the neuropsychological battery established in the present study allows us to show basic differences in the normal coding of stimuli, which can explain the specific visuospatial deficits found in various neurological conditions. 相似文献
