Word list generation (WLG) was examined among clinical samples of individuals with Alzheimer's disease (AD) (n = 73) or ischemic vascular dementia (IVD) (n = 85), equivalent in age, education, current and estimated premorbid intellectual functioning, and proportion of men and women. The AD group performed significantly better than did the IVD group on lexical WLG, and a trend was observed indicating superior performance among the IVD group on categorical WLG. Within-groups, comparisons of group means, and profile analyses of individual performance patterns all indicated that persons with AD demonstrated a lexical > categorical pattern significantly more often than did IVD participants. The absolute difference in average performance between the AD and IVD groups on lexical and categorical WLG was small; the findings, however, generally support the clinical utility of the lexical > categorical WLG pattern in the differential diagnosis of AD and IVD. The patterns of performance support the presence of relative impairment in semantic processing among the individuals with AD and global deficits in retrieval and processing speed in individuals with IVD. 相似文献

The current study presents the test–retest reliability data for the ECO (Examen Cognitif par Ordinateur) computerised cognitive battery developed by Ritchie et al. (1993). Repeat testings were conducted using a sample of 36 healthy elderly with normal cognitive functioning. Sixteen of the battery’s 23 subtests yielded significant correlation coefficients ranging from .42 to .90 (Pearson’s r). A mild practice effect was detected with two of the seven memory tests and two of the seven visuospatial tests (p <.05). Comments about the sources of measurement error and recommendations for further test development are made. 相似文献

The present study explores the indirect effect of job stress on attitudes toward change through individuals’ psychological attachment (organisational commitment mindsets and job embeddedness). The sample comprised N = 350 employees (black African: 67%; males: 69%; 26–40 years: 67%) who were affected by organisational change in the South African fast-moving consumer goods sector. The participants completed self-report measures on their job stress and psychological attachment experiences and their attitudes towards organisational change. The analysis applied structural equation modelling to test for the mediation effect of psychological attachment on the link between job stress and attitudes toward change. The findings suggest job stress to have a direct negative effect on job embeddedness and a positive, direct effect on attitudes toward change. Low levels of job embeddedness had a direct effect on positive attitudes toward change and mediated the link between job stress and attitudes toward change. The study contributes to organisational change theory by suggesting that experiences of job stress lower employees’ job embeddedness and this lowered sense of attachment translates into change-supportive attitudes. 相似文献

A survey study design was used to determine the knowledge of a sample of South African university students regarding the Choice on Termination of Pregnancy (CTOP) Act and their beliefs and attitudes toward abortion. A total of 146 (110 female, 36 male) undergraduate psychology students participated in the study. As part of a larger study participants were given a questionnaire on knowledge, beliefs, attitudes and practices regarding sexuality among young South Africans. The results showed that most of the students were unaware of key provisions of the Act. The data also indicated opposition to abortion except in the case of rape or when the pregnancy posed a threat to the health of the woman. It is concluded that increasing public awareness of the Act is vital not only in improving access to abortion services but also in terms of reducing the stigma that seems to be associated with abortion in South Africa. 相似文献

This study examined the subdimensional structure of the Hogan Personality Inventory (HPI). A sample of 200 Spanish applicants completed the HPI as a requirement of a selection process for several jobs at a large international company. Exploratory factor analyses were conducted with the homogenous item composites (HIC) included in the HPI. Globally, the results indicated that the Big Five are divided into 13 subdimensions, which explained the variance of the HICs. Based on these results, we suggest that the HPI can be described as a personality inventory consisting of a hierarchical structure of three levels (Big Five – subdimensions – HICs). 相似文献

Female U.S. Air Force (USAF) pilots represent a unique group of women in a challenging, high-risk, and male-dominated profession. Aside from ability and motivation, personality characteristics are considered to play a key role in succeeding as a military pilot (Paullin, Katz, Bruskiewicz, Houston, & Damos, 2006). This study evaluated psychological baseline test scores from the NEO Personality Inventory–Revised (NEO PI-R) on the current inventory of rated USAF female (n = 512) and male (n = 9630) pilots in an effort to (a) provide modern normative data on the personality traits of current USAF female pilots, (b) identify personality traits that distinguish female pilots from male pilots and non-pilot females in the civilian normative sample, and (c) assess for meaningful personality differences within female pilots across specific airframes (e.g., fighter/bomber, reconnaissance/surveillance, tanker/transport, and helicopter). The results of the study aim to shed light on objective personality traits and differences and assist clinical psychologists with the interpretation of NEO PI-R psychological test scores when evaluating USAF female pilots. A case vignette is provided to illustrate practical application of study findings. 相似文献

The ability to filter distracting information and selectively attend to relevant information is critical to effective performance on the battlefield. In addition to the cognitive processing burden imposed upon modern warfighters, the effects of stress upon cognition and action must also be accounted for in evaluating individual warfighting capabilities. The current study examines the relationship between stress and cognition by measuring performance on a multiple object tracking (MOT) task after exposure to stress-inducing photographs. Postexposure performance revealed significant decrements in MOT accuracy relative to a nonstressed control group. Implications are discussed regarding the impact of stress on attentional selection for operational scenarios where it is difficult to distinguish friendly individuals from those with hostile intentions, as well as for the development of technology for command, control, communications (computers), and intelligence (C4I) systems. 相似文献

Because military work environments have unique contexts, characteristics, and challenges, military policymakers need to understand how personnel perceive the work environment and how this affects individual and organizational outcomes. This study describes the development and testing of the Navy Climate Index (NCI), a new measure comprising items from the Navy-wide Personnel Survey (NPS) that captures eight aspects of psychological climate: advancement/promotion, autonomy/challenge, leadership, communication, fairness, job security, Tempo, and work group. Using NPS data for 3,610 active duty personnel, confirmatory factor analyses support the validity of the NCI. NCI scores were positively associated with job satisfaction, morale, organizational commitment, and retention intentions. 相似文献

Neuropsychological test interpretation rests upon the assumption that the examinee has exerted full effort. If an individual provides inadequate effort during exam, the resulting data will be invalid and represent an underestimate of the person's true abilities. Although youth have been assumed historically to be less capable of deception than adults, acts of deception in childhood are not uncommon, even in normative populations. Yet, very few cases of children who have provided suboptimal effort during neuropsychological exam have appeared in the scientific literature. We present six clinical cases illustrating that children down to at least age 8 years can present with noncredible performance. The cases include those in which clear external incentives could be identified to those in which intrinsic or psychological factors were presumed to predominate. The fairly diverse nature of the presented cases, along with other recent work, suggests that suboptimal effort in children is apt to occur more frequently than previously recognized, even if it might occur less often than in comparable adult samples. In most of the presented cases, noncredible performance would not have been detected definitively by clinical judgment alone, reinforcing the value of routinely incorporating symptom validity tests into the neuropsychological assessment of school-aged children. The number of effort tests that have demonstrated utility in children pales in comparison to those available to the adult practitioner, although recent research now supports the use of several standalone measures with pediatric patients. 相似文献
