This study was aimed at examining whether pitch height and pitch change are mentally represented along spatial axes. A series of experiments explored, for isolated tones and 2-note intervals, the occurrence of effects analogous to the spatial numerical association of response codes (SNARC) effect. Response device orientation (horizontal vs. vertical), task, and musical expertise of the participants were manipulated. The pitch of isolated tones triggered the automatic activation of a vertical axis independently of musical expertise, but the contour of melodic intervals did not. By contrast, automatic associations with the horizontal axis seemed linked to music training for pitch and, to a lower extent, for intervals. These results, discussed in the light of studies on number representation, provide a new example of the effects of musical expertise on music cognition. 相似文献

Increasing evidence indicates the importance of environmental variables in explaining physical activity. This study evaluated sex differences in perception of home and neighborhood environmental support and assessed which neighborhood environmental variables were associated with reported physical activity of elderly people. A sample of 126 women (M age = 79.1 +/- 6.6 yr.) and 55 men (M age = 76.6 +/- 7.7 yr.) were healthy, community-dwelling individuals. A questionnaire about environmental variables was administered. Physical activity was assessed on the Baecke Questionnaire. Logistic regression analysis showed that Neighborhood Safety was related to total physical activity, activity in leisure time, and sport activities. Men were also likely to be more active in leisure time than women. Neighborhood Personal Safety was associated with physical activity of these elderly people, showing a potential influence of the environmental domain in physical activity. 相似文献

Subjective memory complaint is a self-reported memory impairment which affects elderly people. This problem does not interfere with daily living activities but could decrease quality of life. This study's purpose was to verify whether a specific, newly developed, autobiographical recall training could modify self-perception of memory of subjects with subjective memory complaint. Seven elderly subjects (4 women and 3 men; mean age 65.5 yr., SD=11) with such complaint, evidenced through a specific questionnaire, attended the training course and were prospectively assessed on standard neuropsychological tests, depressive symptomatology, and self-perception of memory. Self-perception of memory, as assessed by scores on a formalized questionnaire, improved significantly after the training, while depressive symptoms did not change. Neuropsychological performances were normal before and after the training, but a statistically significant improvement was observed only on the phonological fluency test. Thus the present pilot study suggested that the training may be effective in improving self-perception of memory and metamnestic capacity in elderly people with subjective memory complaints but not in changing subjects' depressive symptoms. This requires replication of this work with a much larger sample so statistical power is adequate. 相似文献

To assemble a calibrated set of compassion-eliciting visual stimuli, 60 clinically healthy Mexican volunteers (36 women, 24 men; M age = 27.5 yr., SD = 2.4) assessed 84 pictures selected from the International Affective Picture System catalogue using the dimensions of Valence, Arousal, and Dominance included in the Self-assessment Manikin scale and an additional dimension of Compassion. Pictures showing suffering in social contexts and expressions of sadness elicited similar responses of compassion. The highest compassion response was reported for pictures showing illness and pain. Men and women differed in the intensity but not the quality of the compassionate responses. Compassion included attributes of negative emotions such as displeasure. The quality of the emotional response was not different from that previously reported for samples in the U.S.A., Spain, and Brazil. A set of 28 pictures was selected as high-compassion-evoking images and 28 as null-compassion controls suitable for studies designed to ascertain the neural substrates of this moral emotion. 相似文献

Cognitive styles in the context of modern psychology: toward an integrated framework of cognitive style 总被引:5,自引:0,他引:5
Kozhevnikov M 《Psychological bulletin》2007,133(3):464-481
The goals of this article are to elucidate trends and perspectives in the field of cognitive style research and to propose an integrated framework to guide future research. This is accomplished by means of a comprehensive literature review of the major advances and the theoretical and experimental problems that have accumulated over the years and by a discussion of the promising theoretical models that can be further developed, in part, with modern neuroscience techniques and with research from different psychological fields. On the basis of the research reviewed in this article, the author suggests that cognitive styles represent heuristics that individuals use to process information about their environment. These heuristics can be identified at multiple levels of information processing, from perceptual to metacognitive, and they can be grouped according to the type of regulatory function they exert on processes ranging from automatic data encoding to conscious executive allocation of cognitive resources. 相似文献

Strength‐based cultural considerations for counseling Latina/o children and adolescents are not well articulated in the literature. Furthermore, research and demographic data indicate concerns for Latinas/os, such as acculturative stress and discrimination. This article describes treatment applications focused on Latina/o youth's cultural strengths, including family bonds, bilingual abilities, and bicultural skills. Métodos de conserjería basados en rasgos positivos de niños y adolescentes Latinos no se han articulado en la literatura. Además, las investigaciones y los datos demográficos presentan problemas con respeto a presión de acultivación, discriminación, y habilidad limitada en Ingles. Este artículo describe tratamiento centrado en los rasgos culturales positivos de la juventud Latina incluyendo enlaces de la familia, las capacidades bilingües, y las habilidades biculturales. 相似文献

Small G proteins including Rac are mediators of changes in neuronal morphology associated with synaptic plasticity. Previous studies in our laboratory showed that Rac is highly expressed in the adult mouse hippocampus, a brain area that exhibits robust synaptic plasticity and is crucial for the acquisition of memories. In this study, we investigated whether Rac was involved in NMDA receptor-dependent associative fear learning in the area CA1 of adult mouse hippocampus. We found that Rac translocation and activation was increased in the hippocampus following associative fear conditioning in mice, and that these increases are blocked by intraperitoneal injection of the NMDA receptor channel blocker MK801 at the acquisition stage. Our data indicate that NMDA receptor-dependent associative fear learning alters Rac localization and function in the mouse hippocampus. 相似文献

We previously showed that a systemic administration of the selective non-peptide neurokinin-1-receptor (NK-1-R) antagonist SR140333 increases hippocampal acetylcholine levels and facilitates long term memory. In the present study, we investigated whether systemic SR140333 has beneficial effects on episodic-like memory for unique experiences. Rats received either no injection, a vehicle injection or SR140333 at doses of 1, 3 and 9 mg/kg (i.p.) prior to the acquisition of an object memory for what, where and when. In line with previous results, untreated rats showed episodic-like memory, while vehicle-injected rats were impaired. A low dose of 1mg/kg SR140333 reinstated episodic-like memory. This result might be related to the effects of SR140333 on hippocampal cholinergic transmission and/or on the stress-response elicited by the injection procedure. Higher doses of SR140333 (3 and 9 mg/kg) induced psychomotor effects, including stereotypic behaviors and arched posture. Since NK-1-R antagonists have anxiolytic and promestic properties and induce hippocampal acetylcholine release at lower doses, they might be effective in the alleviation of the cognitive deficits and increased anxiety seen in early stages of Alzheimer's disease. 相似文献
