The aim of this study was to investigate the accuracy of the Portuguese version of Addenbrooke’s Cognitive Examination–Revised (ACE-R) in detecting and differentiating early stage subcortical vascular dementia (SVD) from early stage Alzheimer’s disease (AD). Ninety-two subjects (18 SVD patients, 36 AD patients, and 38 healthy controls) were assessed using the ACE-R. Between-group’s differences were evaluated using the Quade’s rank analysis of covariance. The diagnostic accuracy and discriminatory ability of the ACE-R were examined via receiver operating characteristic (ROC) analysis. The ACE-R was able to successfully discriminate between patients and healthy subjects. The mean ACE-R total scores differed between SVD and AD patients; there were also significant differences in attention and orientation and in memory measures between the groups. An optimal cut-off of 72/73 was found for the detection of AD (sensitivity: 97%; specificity: 92%) and SVD (sensitivity: 100%; specificity: 92%). 相似文献

Trust plays a crucial role in interpersonal relationships, including customer–company relationships, where the customer expects that a company will behave predictably in any particular situation. Companies do not always fulfill customers' expectations and thereby breach the trust relationship. To avoid negative consequences of this trust violation, companies may issue a formal apology as one possible path to regaining customer trust. In the same way, a previous social interaction, which can increase the customer's levels of oxytocin, can help to recover trust after service failures. In this study, three experiments were conducted as follows: the first manipulating a simulated social interaction with images; the second manipulating a physical social interaction, (i.e., a hug); and the third with exogenous oxytocin administration. The results showed that both physical interaction, (i.e., a hug) and simulated social interaction, (i.e., images of people interacting with each other) had a positive effect on customer trust recovery and provided support for oxytocin release as the underlying mechanism in this process. This research contributes to understanding of the link between social interactions and trust by elucidating the effects of both simulated and physical interactions on trust recovery. 相似文献

This work presents an analysis of the role of animacy in attachment preferences of relative clauses to complex noun phrases in European Portuguese (EP). The study of how the human parser solves this kind of syntactic ambiguities has been focus of extensive research. However, what is known about EP is both limited and puzzling. Additionally, as recent studies have stressed the importance of extra-syntactic variables in this process, two experiments were carried out to assess EP attachment preferences considering four animacy conditions: Study 1 used a sentence-completion-task, and Study 2 a self-paced reading task. Both studies indicate a significant preference for high attachment in EP. Furthermore, they showed that this preference was modulated by the animacy of the host NP: if the first host was inanimate and the second one was animate, the parser's preference changed to low attachment preference. These findings shed light on previous results regarding EP and strengthen the idea that, even in early stages of processing, the parser seems to be sensitive to extra-syntactic information. 相似文献

This study describes the validity and reliability evidence of the multidimensional measure of employability (MME) based on the internal structure and relations to career self-efficacy and career success. Two hundred forty seven Portuguese persons (75.7% women) aged from 21–73 years old (M = 39.9, SD = 10.9) participated. Confirmatory factor analysis suggested adequate fit in the correlational and hierarchical models. Measurement reliability was good for total score and each factor. Correlations with the additional measures provided evidence of validity. MME provides a tool for research and career counseling, enabling comprehensive employability assessment and personalized interventions, while recognising the interplay between employability dimensions. 相似文献

In a large, community-based sample of women (N = 750), the authors examined the nature of associations between dysfunctional attitudes and depression. Dysfunctional attitudes were evaluated both as a vulnerability factor for depression and as a consequence of depression. A link was found between past depression and baseline elevations in dysfunctional attitudes that was independent of current subsyndromal symptoms, but intensification of dysfunctional attitudes following prospectively evaluated episodes of depression (depressive "scarring") was not observed. Although baseline dysfunctional attitudes predicted an episode of major depression over 3 years of prospective study, this prediction, considered alone or in interaction with negative life events, was redundant with that offered by history of past depression. Further, no significant prediction was evident for the Dysfunctional Attitude Scale (A. N. Weissman & A. T. Beck, 1978) when the formerly depressed and never-depressed cohorts were considered separately. Implications for cognitive theories are discussed. 相似文献

Self‐monitoring to increase the on‐task behavior of students with learning disabilities has been the focus of numerous studies in the literature. This study examined the effectiveness of computer aided self‐monitoring of academic task completion to reduce self‐injurious behavior in a 13‐year‐old male student with autism. Using an ABAB design, data were collected over 22 sessions in a resource‐reading classroom. Visual and statistical analyses indicated that when self‐monitoring of activity completion was implemented, rates of completion increased and maladaptive behaviors such as self‐injurious behavior and tantruming decreased. Discussion follows for implications for self‐monitoring with students with autism. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

Word-finding deficits are a common problem in aphasic patients. One hypothesis suggests that the difficulty that patients experience in naming objects or pictures is related to a disruption in the ability to access the lexicon. Another hypothesis suggests that these problems are caused by a disruption of the mental dictionary and the semantic representations contained in it. The main purpose of this study is to assess whether nonverbal factors such as the ability to distinguish between similar attributes of objects is related to word-use problems in aphasia. 14 adults with left hemisphere cerebrovascular accidents and some word use deficit were administered the first 30 items of the Boston Naming Test and the Conceptual Matching subtest of the Detroit Test of Learning Aptitude. Errors on the Conceptual Matching subtest correlated significantly with the number of semantic paraphasias. 相似文献

This article presents a model of interaction of personal and contextual variables in the prediction of academic performance and psychosocial development of Portuguese college students. The sample consists of 560 first-year college students of the University of Minho. The path analysis results suggest that initial expectations of the students' involvement in academic life constituted an effective predictor of their involvement during their first year; as well as the social climate of the classroom influenced their involvement, well-being and levels of satisfaction obtained. However, these relationships were not strong enough to influence the criterion variables integrated in the model (academic performance and psychosocial development). Academic performance was predicted by the high school grades and college entrance examination scores, and the level of psychosocial development was determined by the level of development showed at the time they entered college. Though more research is needed, these results point to the importance of students' pre-college characteristics when we are considering the quality of their college adjustment process. 相似文献

The objective of the present study was to observe the effects of pre-training or post-training administration of dicyclomine, a M1 muscarinic antagonist, on inhibitory avoidance (IA) and contextual fear conditioning (CFC) and to investigate if the effects observed with the pre-training administration of dicyclomine are state-dependent. For each behavioral procedure (IA and CFC) groups of Wistar male rats were treated with saline or dicyclomine either 30 min before training (pre-training), immediately after training or 30 min before training/30 min before test (pre-training/pre-test). The animals were tested 24 h after training. The acquisition of IA and CFC was impaired by pre-training administration of dicyclomine. The consolidation of both tasks was not affected by dicyclomine given immediately after training. Pre-training/pre-test administration of dicyclomine impaired both tasks, an effect similar to that observed in the group which only received pre-training administration. Pre-test treatment induced dissociation between both tasks, impairing CFC retrieval, without interfering with the animals avoidance response. These results show that the dicyclomine did not affect IA and CFC consolidation, suggesting specific involvement of M1 muscarinic receptor only in acquisition these tasks, and these effects was not state-dependent. However, it is possible that the retrieval of these tasks may be mediated, at least in part, by different neurochemical mechanisms and may be dissociated by dicyclomine. 相似文献
