Subjects (n = 246) were asked to identify the trait(s) measured by Rotter's Interpersonal Trust Scale with and without filler items, either by responding freely or by circling traits listed on a sheet. Half the subjects were informed prior to filling out the questionnaire that their task was to identify the traits being measured by the questionnaire; the remaining half of the subjects were informed of their task after they completed the questionnaire. Very few subjects were able to identify correctly the trait being measured by Rotter's scale regardless of the experimental condition. Most subjects named multiple traits. It was concluded that the use of filler items per se was not the key factor in disguising the true purpose of Rotter's test; rather item wording may have produced multiple interpretations. 相似文献

This study examines profile, research area, research activities, perception of psychology, self-image and profession-related satisfaction doctoral students of psychology in India. Seventy-seven participants responded to a mailed questionnaire. It has subsections related to self-image as researcher, student-supervisor relationship, research process, profession-related satisfaction, and status of psychology in India. It was observed that most participants belonged to urban background, middle class, and nuclear family. They perceived job opportunities in various fields and aspired most for teaching and research. Further, gender and financial assistance did not influence self-image and student-supervisor relationship. However, financial assistance influenced satisfaction with different aspects of profession. Implications of the findings are discussed in light of doctoral training of psychology in India and reorientation of psychology as a profession. 相似文献

The significance of the role of Neuroticism (N) as an important determiner of learning and performance was investigated. The relation of N to performance on intelligence tests was analyzed and it was predicted that as item difficulty increased high N subjects would perform progressively worse and low N subjects would perform better. This type of analysis was shown to demonstrate the Yerkes-Dodson phenomenon better than a single total test score. In the present investigation, 400 subjects were selected for a 2 × 2 design consisting of two personality groups (neurotics vs. stables) and two sexes. Subjects were administered the Standard Progressive Matrices, an intelligence test having five progressively more difficult stages. The findings were that neurotics performed better on the simpler set, but as items became more difficult the stables performed significantly better than neurotics. A correlational analysis also showed a positive relation between N and the first set of items, and a negative relation between N and the other four sets. 相似文献

Although social justice is an integral component of medical professionalism, there is little discussion in medical education about how to teach it to future physicians. Using adult learning theory and the work of Brazilian educator Paulo Freire, medical educators can teach a socially-conscious professionalism through educational content and teaching strategies. Such teaching can model non-hierarchical relationships to learners, which can translate to their clinical interactions with patients. Freirian teaching can additionally foster professionalism in both teachers and learners by ensuring that they are involved citizens in their local, national and international communities. 相似文献

Canavan disease: a white matter disorder 总被引:1,自引:0,他引:1
Kumar S Mattan NS de Vellis J 《Mental retardation and developmental disabilities research reviews》2006,12(2):157-165
Breakdown of oligodendrocyte-neuron interactions in white matter (WM), such as the loss of myelin, results in axonal dysfunction and hence a disruption of information processing between brain regions. The major feature of leukodystrophies is the lack of proper myelin formation during early development or the onset of myelin loss late in life. These early childhood WM diseases are described as hypomyelination or dysmyelination arising from a primary block in normal myelin synthesis because of a genetic mutation expressed in oligodendrocytes, or failure in myelination secondary to neuronal or astroglial dysfunctions (van der Knaap 2001 Dev. Med. Child Neurol. 43:705-712). Here, we describe the pathophysiological parameters of Canavan disease (CD), caused by genetic mutations of the aspartoacylase (ASPA) gene, a metabolic enzyme restricted in the central nervous system (CNS) to oligodendrocytes. CD presents pathophysiological dysfunctions similar to diseases caused by myelin gene mutations, such as Pelizaeus-Merzbacher disease (PMD) and several animal models, such as myelin deficient rat (md), jimpy (jp), shiverer (sh), and quaking (qk viable) mutant mice. These single gene mutations have pleiotropic effects, whereby the alteration of one myelin gene expression disrupts functional expression of other oligodendrocyte genes with an outcome of hypomyelination/dysmyelination. Among all of the known leukodystrophies, CD is the first disorder, which was approved and tested for the adeno-associated virus vector (AAV)-ASPA gene therapy (Leone et al. 2000 Ann. Neurol. 48:27-38; Janson et al. 2001 Trends Neurosci. 24:706-712) without much success following the first two attempts. ASPA gene delivery attempts in animal models have shown a lowering of N-acetyl L-aspartate and a change in motor functions, while sponginess of the WM, a characteristic of CD remained unchanged (Matalon et al. 2003 Mol. Ther. 7 (5, Part 1):580-587; McPhee et al. 2005 Brain Res. Mol. Brain Res. 135:112-121) even with better viral serotype and delivery of the gene during early phase of development (Klugmann et al. 2005 Mol. Ther. 11:745-753). While different approaches are being sought for the success of gene therapy, there are pivotal developmental questions to address regarding the specific regions of the CNS and cell lineages that become the target for the onset and progression of CD symptoms from early to late stages of development. 相似文献

Despite the growing number of organizations interested in the use of asynchronous video interviews (AVIs), little is known about its impact on interviewee reactions and behavior. We randomly assigned participants (N = 299) from two different countries (Switzerland and India) to a face-to-face interview, an avatar-based video interview (with an avatar as a virtual recruiter), or a text-based video interview (with written questions) and collected data on a set of self-rated and observer-rated criteria. Overall, we found that whereas participants reported more negative reactions towards the two asynchronous interviews, observer ratings revealed similar performance across the three interviews and lower stress levels in the two AVIs. These findings suggest that despite technology-mediated interview methods still not being well-accepted, interviewees are not at a disadvantage when these methods are used in terms of how well interviewees perform and how stressed they appear to external observers. Implications are discussed. 相似文献

Using cross-sectional data from N = 4274 young adults across 16 countries during the COVID-19 pandemic, we examined the cross-cultural measurement invariance of the perceived vulnerability to disease (PVD) scale and tested the hypothesis that the association between PVD and fear of COVID-19 is stronger under high disease threat [that is, absence of COVID-19 vaccination, living in a country with lower Human Development Index (HDI) or higher COVID-19 mortality]. Results supported a bi-factor Exploratory Structural Equation Modeling model where items loaded on a global PVD factor, and on the sub-factors of Perceived Infectability and Germ Aversion. However, cross-national invariance could only be obtained on the configural level with a reduced version of the PVD scale (PVD-r), suggesting that the concept of PVD may vary across nations. Moreover, higher PVD-r was consistently associated with greater fear of COVID-19 across all levels of disease threat, but this association was especially pronounced among individuals with a COVID-19 vaccine, and in contexts where COVID-19 mortality was high. The present research brought clarity into the dimensionality of the PVD measure, discussed its suitability and limitations for cross-cultural research, and highlighted the pandemic-related conditions under which higher PVD is most likely to go along with psychologically maladaptive outcomes, such as fear of COVID-19. 相似文献

To provide information on the use of the Beck Depression Inventory-II (BDI-II) with adolescents, the BDI-II was administered to 105 male and 105 female outpatients between 12 and 18 years old who were seeking psychiatric treatment. The internal consistency of the BDI-II was high (coefficient = .92). The mean BDI-II total score of the girls was approximately 5 points higher than that of the boys (p < .001), and age (years) was positively correlated with the BDI-II total scores (r = .18, p < .01). An iterated principal-factor analysis identified three factors, but only the Cognitive and Somatic-Affective factors were generalizable. 相似文献

We investigated the relationship between changes in perceptions of competence and changes in achievement goals across a college
semester for students enrolled in an introductory psychology course. Two types of competence perceptions were examined: self-efficacy
for learning and normative perceived ability. Changes in normative perceived ability were predicted to relate to changes in
performance goals, but not mastery goals. Because mastery goals rely on self-referent standards to evaluate ability, we predicted
changes in self-efficacy for learning would relate to changes in mastery goals. We also expected changes in self-efficacy
for learning to relate to changes in performance goals because learning can lead to the demonstration of superior competence.
The predictions were supported for mastery and performance-approach goals, but not for performance-avoidance goals. Very little
change in performance-avoidance goals was observed. Scores on the first course exam also predicted change in performance-approach
goals, with this effect partially mediated by competence perceptions. 相似文献
