It has long been known that eye movements are functionally involved in the generation and maintenance of mental images. Indeed, a number of studies demonstrated that voluntary eye movements interfere with mental imagery tasks (e.g., Laeng and Teodorescu in Cogn Sci 26:207–231, 2002). However, mental imagery is conceived as a multifarious cognitive function with at least two components, a spatial component and a visual component. The present study investigated the question of whether eye movements disrupt mental imagery in general or only its spatial component. We present data on healthy young adults, who performed visual and spatial imagery tasks concurrently with a smooth pursuit. In line with previous literature, results revealed that eye movements had a strong disruptive effect on spatial imagery. Moreover, we crucially demonstrated that eye movements had no disruptive effect when participants visualized the depictive aspects of an object. Therefore, we suggest that eye movements serve to a greater extent the spatial than the visual component of mental imagery.  相似文献

It is still controversial to what extent neocortical consolidated memories are susceptible of change by processes of reconsolidation and transformation throughout experience, and whether the medial temporal lobes are necessary for this update of semantic consolidated memories, as they are for episodic remembering. We hypothesize that patients with amnestic mild cognitive impairment (aMCI) who have deficits in episodic memory may also have difficulties in updating information on added new features of objects. Sixteen participants with aMCI and 20 healthy control participants performed a semantic word-to-picture task, in which they were asked to identify as belonging to a given semantic category NEW objects, that have incorporated novel features, as well as OLD items, semantically and visually SIMILAR items and UNRELATED items. Patients with aMCI made a greater percentage of errors than healthy controls. Participants globally made greater percentages of errors in difficult types of items, namely NEW and SIMILAR, as compared to easier ones, OLD and UNRELATED. Importantly, an item by diagnostic group interaction effect was observed, and post hoc analysis showed that patients with aMCI made a higher percentage of errors than controls in NEW items only. In conclusion, patients with aMCI had a particular difficulty in identifying the NEW items of the word-to-picture task as compared to the control participants, supporting the concept of a flexible and dynamic conceptual knowledge system, involving the update of semantic memories and the integration of new attributes in a constant transformation process, which is impaired in these patients.  相似文献

Dental education programs are known to be highly stressful and stress can affect general health. The aims were to identify sources of stress among preclinical students and to evaluate their perceived levels of stress, self-efficacy and effective coping strategies in a private dental school. One hundred preclinical students in a Turkish private dental school were surveyed using dental environment stress (DES), perceived stress (PSS), general self-efficacy (G-SES) and brief coping scales (Brief-COPE). Age, gender, history of psychiatric treatment, factors that affected the choice of dentistry, choice rank of dental school, scholarship and income was recorded. ‘Exams and grades’ followed by ‘Fear of failing course or year’ were found to be the most stressprovoking factors. The most and the least stressprovoking DES domains were ‘Workload’ and ‘Social stressors’, respectively. ‘Social stressors’ affected male more than female (p < .05). The most and the least common coping strategies were found to be ‘Planning’, and ‘Drug’, respectively. Female used ‘Instrumental support’ more than male (p < .05). Demographic factors had impact on the perceived stress factors and levels, as well as coping strategies. Unlike previous studies establishing high stress levels in dental students, preclinical students displayed moderate level of stress. Clinical dental education might be more responsible for creating stress.  相似文献

Rheumatoid arthritis (RA) prevalence increases with age and old people are special patient population. The recognition of functional disability related to RA could be challenging in elderly patients because aging itself and potential co-morbid disease may also cause functional disability. In this study, we aimed to look at the correlation between disease activity and functional disability in elderly RA patients. Elderly RA patients, ≥65 years old at their routine visits were included in the study. The composite ‘disease activity score’ in 28 joints (DAS-28) was used to determine disease activity groups. Health assessment questionnaire (HAQ) scores were calculated to describe the functional disability and compared across the disease activity groups. Two hundred and fifty-eight RA patients with the mean age of 71 ± 5 (65–90) and a total disease duration of 8.4 ± 8.5 (.5–50) years were recruited. The proportion of patients with high and moderate disease activity was 70%. HAQ scores were significantly correlated with disease activity (p < .05). Functional disability estimated by HAQ was correlated with disease activity in elderly patients with RA  相似文献

Abstract

Over the last two decades, Worldview Approach has been mentioned in the field of religious education and spirituality. This article aims to determine the effects of creative drama on teaching worldviews and religions. The main purpose of Worldview Education is to assist individuals to have a broader and deeper understanding on self-identity, worldviews of others, and on the meaning and purpose of life. It also helps individuals to think on ontological, epistemological and ultimate questions about life, values and beliefs. The spiritual development of individuals has a need for several guidelines from the fields of philosophy, theology, and education. As an educational tool, creative drama increases imagination, creativity, problem-solving and critical thinking skills and assists students’ personal and emotional development. Combining Worldview Education with creative drama creates a multidimensional educational environment for a meaningful learning on religions, worldviews, and spirituality.  相似文献

A limited number of measures assess young adults’ perceptions of childhood disorganized and controlling attachment, and although they are empirically strong, the use of these measures can be time consuming and financially straining. The current study aimed to add to the attachment literature by developing a self-report measure, the Childhood Disorganization and Role Reversal Scale (CDRR), to assess for the complexity of those attachment constructs in young adults. This study aimed to assess the psychometric properties of the CDRR using two separate samples of 750 and 656 undergraduate students (601 females; Mage?=?18.68, 66.4% Caucasian; 531 females; Mage?=?18.68 years, 63.6% Caucasian; respectively), and a community sample of 96 participants (81 females, Mage?=?19.27, 65.6% Caucasian). The results of the Principal Component Analysis (PCA) revealed a four-factor structure for both CDRR parent versions. The CDRR mother version includes the Disorganization/Punitive, Mutual Hostility, Affective Caregiving, and Appropriate Boundaries scales, while the CDRR father version includes the Disorganization, Affective Caregiving, Appropriate Boundaries, and Punitive scales. Overall, support was provided for the psychometric properties of the CDRR. For instance, the CDRR scales demonstrated adequate structural stability (confirmatory factor analyses), internal consistency (Cronbach’s coefficient alphas ranged from .78–.95 for mother scale, and .75–.96 or father scale), temporal reliability (intraclass correlation coefficient ranged from .68–.89 for mother scale, and .69–.87 for father scale), criterion-related validity, convergent validity, and discriminant validity. The CDRR will assist researchers in broadening the understanding of psychological outcomes of disorganized and controlling attachment representations in young adulthood.  相似文献
