Impairments of word recognition in Alzheimer's disease (AD) have been less widely investigated than impairments affecting word retrieval and production. In particular, we know little about what makes individual words easier or harder for patients with AD to recognize. We used a lexical selection task in which participants were shown sets of four items, each set consisting of one word and three non‐words. The task was simply to point to the word on each trial. Forty patients with mild‐to‐moderate AD were significantly impaired on this task relative to matched controls who made very few errors. The number of patients with AD able to recognize each word correctly was predicted by the frequency, age of acquisition, and imageability of the words, but not by their length or number of orthographic neighbours. Patient Mini‐Mental State Examination and phonological fluency scores also predicted the number of words recognized. We propose that progressive degradation of central semantic representations in AD differentially affects the ability to recognize low‐imageability, low‐frequency, late‐acquired words, with the same factors affecting word recognition as affecting word retrieval. 相似文献

Status Incongruence and Supervisor Gender as Moderators of the Transformational Leadership to Subordinate Affective Organizational Commitment Relationship 下载免费PDF全文
Grounded in role congruity theory, we examine how status incongruence (when the subordinate is older, has more education, work experience, and/or organizational tenure than the supervisor) in subordinate–supervisor dyads affects transformational leaders’ ability to foster affective organizational commitment among their subordinates. Across two field studies, our findings show that the relationship between transformational leadership and subordinate affective organizational commitment is less positive when status incongruence is high. Furthermore, in both field studies we found a 3‐way interaction among transformational leadership, status incongruence, and supervisor gender predicting subordinate affective organizational commitment. Specifically, in Study 1 (pink‐collar employees in Turkey), low status incongruence strengthened the positive relationship between transformational leadership and subordinate affective organizational commitment for male leaders. In Study 2 (pink‐collar employees in the United States), low status incongruence strengthened the positive relationship between transformational leadership and subordinate affective organizational commitment for female leaders. Furthermore, Study 2 also revealed that collective identity was a mediator of both the significant 2‐ and 3‐way interaction effects on subordinate affective organizational commitment. 相似文献

The reaction time has been described as a measure of perception, decision making, and other cognitive processes. The aim of this work is to examine age‐related changes in executive functions in terms of demand load under varying presentation times. Two tasks were employed where a signal detection and a discrimination task were performed by young and older university students. Furthermore, a characterization of the response time distribution by an ex‐Gaussian fit was carried out. The results indicated that the older participants were slower than the younger ones in signal detection and discrimination. Moreover, the differences between both processes for the older participants were higher, and they also showed a higher distribution average except for the lower and higher presentation time. The results suggest a general slowdown in both tasks for age under different presentation times, except for the cases where presentation times were lower and higher. Moreover, if these parameters are understood to be a reflection of executive functions, these findings are consistent with the common view that age‐related cognitive deficits show a decline in this function. 相似文献

Black Mountain College is remembered as an artistic utopian alternative to institutional learning. Its faculty and students included some of the most important creative thinkers of the 20th century. Its foundation was built on the philosophy of “learning by doing.” But what made Black Mountain such a dynamic educational environment? Today, the financial burden of higher education places a lasting strain on students that inhibits creative growth. Does the educational structure of the college system impede our learning? Black Mountain was a legendary educational experiment, which offers a model for contemporary art education. 相似文献

This study examined the role of anxiety sensitivity as an explanatory variable in the link between two temperamental dimensions (i.e., behavioral inhibition and negative affect) and anxiety disorder symptom severity in a sample of children with anxiety disorders. Forty-four children (52?% African American) between 8 and 12 years of age and their mothers participated in this study. An assessment battery consisting of diagnostic interviews, questionnaires, and behavioral assessment of behavioral inhibition was administered. Findings revealed that anxiety sensitivity was a significant explanatory variable linking child self-reports of behavioral inhibition and negative affect to anxiety disorder symptom severity. For parent-completed measures, only direct effects of behavioral inhibition on anxiety disorder symptom severity were found. The clinical implications of our findings, including the importance and feasibility of anxiety sensitivity and behavioral inhibition assessments as part of routine clinical care of children with anxiety disorders are discussed, along with the limitations of our study. 相似文献

Mentoring can support all aspects of women's professional (and often personal) lives as students, educators, researchers, practitioners, and leaders in the counseling profession. So that female mentors and mentees know what to expect from each other, the authors draw upon the mentoring literature and their own experiences in mentoring relationships to provide guidelines for mentoring relationships by defining the means and ends that can be used to establish and maintain woman‐to‐woman professional mentoring in higher education. 相似文献

In this article, normative data on the familiarity and difficulty of 196 single-solution Spanish word fragments are presented. The database includes the following indices: difficulty, familiarity, frequency, number of meanings, number of letters given in the fragment, first and/or last letters given, and ratio of letters to blanks. A factor analysis was performed on difficulty, and two factors were obtained. Frequency, familiarity, and number of meanings loaded highly on the first factor, which we consider to measure lexical processes, whereas number of letters in the fragment, first and/or last letters given, and ratio of letters to blanks loaded highly on the second factor, which we judge to be determined by perceptual information. Regression analyses using factor scores as predictors showed that both factors accounted for a significant part of the completion probability scores.

Geoffrey Loftus, Editor of Memory & Cognition from 1994 to 1997, strongly encouraged presentation of figures with error bars and avoidance of null hypothesis significance testing (NHST). The authors examined 696 Memory & Cognition articles published before, during, and after the Loftus editorship. Use of figures with bars increased to 47% under Loftus's editorship and then declined. Bars were rarely used for interpretation, and NHST remained almost universal. Analysis of 309 articles in other psychology journals confirmed that Loftus's influence was most evident in the articles he accepted for publication, but was otherwise limited. An e-mail survey of authors of papers accepted by Loftus revealed some support for his policy, but allegiance to traditional practices as well. Reform of psychologists' statistical practices would require more than editorial encouragement. 相似文献

Researchers and educational writers provide many views on what characteristics and skills the college graduate should possess (P. D. Gardner, 1998). Given the rapidly changing nature of knowledge in all disciplines and the subjectivity of grading systems, we argue the best indicator of a successful college education is a student's ability to think complexly about difficult problems. In this paper we examine students' levels of intellectual development to inform our understanding of how college experiences affect students' abilities to think in complex ways about difficult problems. Using both qualitative and quantitative research techniques, we examine and compare the experiences of 19 senior college students who were rated at opposite ends of the Perry scheme of intellectual development. The 19 students were purposefully selected to represent the high and low ends of the Perry scale from an overall sample of 27 senior students at a large eastern university. Ten students from the original sample of 27 demonstrated the most advanced cognitive development with Perry scale ratings of 5–7. Nine students had Perry ratings below 4; this was the lowest rating represented in the sample. We examine the similarities and differences between these two sets of students' academic profiles, and their comments about their curricular experiences, and how the Perry scale reflects on these results. We then discuss how these similarities and differences relate to students' development of the desirable characteristics of a college graduate, implications for faculty and administrators, and the relationship of these results to prior studies using the Perry scheme. 相似文献
