ABSTRACT Impairments in visual attention and visual information processing have been identified as part of the neuropsychological features of Alzheimer's disease (AD), even in its earliest stages. There is increasing recognition that these deficits may be selective rather than global, with some attentional subtypes being more vulnerable than others. The few studies that have investigated attentional deficits in mild cognitive impairment (MCI), a putatively prodromal phase of AD, have not satisfactorily addressed the possible selectivity in attentional deficits in MCI. This study examined potential dissociations in visual attention deficits in MCI using a measure that assesses simple, divided, and selective attention. The results indicated a hierarchy of attentional impairments, with divided attention being the most affected and simple attention the least. Among participants with MCI, 53% showed evidence of impairment in divided attention compared to 19% of controls (OR = 4.81, p < .001). Poorer visual attention was also associated with poorer overall cognitive status. The implications of these findings for early identification of MCI, prevention of functional decline in MCI, and delay/reversal of cognitive degradation in MCI are discussed. 相似文献

The purpose of this study was to examine the associations between reading motivation and inference generation while reading. Undergraduate participants (N = 69) read two science articles while thinking aloud, completed a standardized reading comprehension assessment, and self reported their habitual reading motivation. Findings indicate that overall reading motivation, one component of intrinsic motivation (reading as a sense of self), and one component of extrinsic motivation (reading to do well in other realms) were positively associated with text-connecting inference generation independent of reading comprehension skill. These findings are discussed in the context of standards of coherence. 相似文献

Reconceptualizing individual differences in self-enhancement bias: an interpersonal approach 总被引:4,自引:0,他引:4
Self-enhancement bias has been studied from 2 perspectives: L. Festinger's (1954) social comparison theory (self-enhancers perceive themselves more positively than they perceive others) and G. W. Allport's (1937) self-insight theory (self-enhancers perceive themselves more positively than they are perceived by others). These 2 perspectives are theoretically and empirically distinct, and the failure to recognize their differences has led to a protracted debate. A new interpersonal approach to self-enhancement decomposes self-perception into 3 components: perceiver effect, target effect, and unique self-perception. Both theoretical derivations and an illustrative study suggest that this resulting measure of self-enhancement is less confounded by unwanted components of interpersonal perception than previous social comparison and self-insight measures. Findings help reconcile conflicting views about whether self-enhancement is adaptive or maladaptive. 相似文献

In this study, 22 children with early left hemisphere (LHD) or right hemisphere (RHD) focal brain lesions (FL, n=14 LHD, n=8 RHD) were administered an English past tense elicitation test (M=6.5 years). Proportion correct and frequency of over-regularization and zero-marking errors were compared to age-matched samples of children with specific language impairment (SLI, n=27) and with typical language development (TD, n=27). Similar rates of correct production and error patterns were observed for the children with TD and FL; whereas, children with SLI produced more zero-marking errors than either their FL or TD peers. Performance was predicted by vocabulary level (PPVT-R) for children in all groups, and errors did not differ as a function of lesion side (LHD vs. RHD). Findings are discussed in terms of the nature of brain-language relations and how those relationships develop over the course of language learning. 相似文献

We used the Rasch (1980) model to develop new pictures for the Thematic Apperception Test (C. D. Morgan & Murray, 1938; McClelland, Atkinson, Clark, & Lowell, 1953) or picture story exercise to measure need for achievement (nAch). In Experiments 1 and 2, we analyzed stories to assess the difficulty level of a total of 8 pictures using the multifaceted Rasch model with picture difficulty, story probe difficulty, and participant ability as facets with a partial credit model (FACETS; Linacre, 2005). A total of 6 pictures were retained and 4 new ones added for Experiment 3 in which 201 participants wrote 6 stories to a random set of the 10 pictures. FACETS analysis revealed improved person separation reliability. In Experiment 4, 206 participants wrote 1 story to the Studying picture either before or after filling out a battery of achievement-related questionnaires. The 2 experimental groups did not differ in the amount of nAch in their stories. The coder facet was demonstrated with 2 independent coders using the revised coding system for nAch. 相似文献

The aim of this study was to provide insight into the contribution of marching band to overall physical activity. A convenience sample was recruited from the Arizona State University Marching Band. Participants logged their physical activity and step counts for seven days. Complete data were returned by 49 participants. Repeated measures analysis of variance (ANOVA) revealed that participants took significantly more steps per day on marching band days compared to days that did not involve marching band. These findings suggest that marching band can help to meet current physical activity recommendations when measured in steps-per-day using a pedometer. 相似文献

This study is based on a sample of 332 Argentinean teenagers in their last year of secondary school. In the context of the relational theory of motivation, an attempt is made to determine the motivational categories best predicting Future Time Perspective (FTP) extension. The influence of the sex, locus of control, social class, and school ethos variables on FTP extension is also explored. A scale measuring locus of control and the Motivational Induction Method (MIM) have been employed to obtain the data. Through stepwise multiple regression, a predictive set is determined, made up of life-meaning values, self-fulfillment, academic achievement motivation, locus of control, sensual values, and social contact. Significant differences are found in FTP extension and locus of control in relation to school ethos. The Mann-Whitney and Kruskal-Wallis tests are used as statistical proof. A one-way ANOVA is run to examine the relationship between locus of control and school ethos levels. The possibility of a motivational profile common to Argentinean teenagers is considered and the pedagogical consequences of the findings are discussed. 相似文献

Group psychotherapists in their everyday practice confront a series of ethical problems, some of which rise to the level of ethical dilemmas. This two-part special series will address how the group psychotherapist can address these problems and dilemmas in a way that leads to an ethical course of conduct. This article introduces the series by examining ethical principles and decision-making processes that are relevant to the wide range of issues that confront the group psychotherapist. The article also considers the person of the group psychotherapist him or herself and notes that certain personal qualities might create a foundation for ethical thinking and behavior. 相似文献

This paper investigates the relationship between resilience and positive/negative mental aspects of psychological well-being in formal caregivers for the elderly. The sample consisted of 265 caregivers who work in different residential homes in Extremadura and Castilla y León (Spain). The instruments used included the Connor-Davidson Resilience Scale , the Maslach Burnout Inventory-General Survey and the Utrecht Work Engagement Scale. The most significant findings show that caregivers with higher levels of resilience also have higher levels of professional efficacy and job engagement (vigor, dedication and absorption) and appear to be less emotionally exhausted or cynical than caregivers with lower levels of resilience. It cannot be concluded that more resilient caregivers will not get burned out, but they develop better engagement skills. As they strengthen these personal attributes, they become less vulnerable to burnout. 相似文献
