The factor structure of the Reynolds Child Depression Scale (RCDS; Reynolds, 1989), analyzed by confirmatory factor analysis and the scale's psychometric characteristics in a sample of 315 participants (140 boys and 175 girls) and a clinical sample of 62 participants (37 boys and 25 girls) between 10 and 12 years old, are presented. Two models are tested with confirmatory factor analysis: a one-factor model and a five-factor model. Both models show a good fit, but the one-factor model was chosen because it is the most parsimonious. The reliability coefficient ranged from .87 (at test) to .89 (at retest) in the community sample, and was .90 in the clinical sample (at test). Test-retest reliability was .66 in the community sample. Concurrent validity with other self-reports that measure depressive symptomatology was high, both in the community sample (.76) and the clinical sample (.71). There were no significant sex differences but there were differences due to age (school grade). 相似文献

We report the naming performance of an early and highly proficient Spanish-Catalan bilingual (JPG) suffering from Primary Progressive Aphasia (PPA). JPG's performance revealed a grammatical category-specific deficit, with worse performance in naming verbs than nouns. This dissociation was present in oral and written naming and in his two languages, and it seems to stem from damage to, at least, the lexical level. Despite the fact that JPG's performance was qualitatively very similar across languages, his second language seemed to be more affected than his first language. These results indicate that the cortical organization of the two languages of highly proficient bilinguals follow similar organizational principles, one of this principles being grammatical class. 相似文献

We investigated the right-left prevalence effect in spatial compatibility tasks by assessing subjects’ performance on a two-dimensional task in which both the horizontal and vertical spatial dimensions were task relevant. Two experiments were performed, in which stimulus-response mappings were one-dimensional (Experiment 1) and two-dimensional (Experiment 2). The subjects responded by using either horizontal or vertical effectors to stimuli appearing in four possible locations. With the one-dimensional mapping, the spatial compatibility effect was present only in the dimension relevant to the mapping. With the two-dimensional mapping, the horizontal compatibility effect was always present, whereas the vertical compatibility effect was present only when vertical effectors were used. This pattern of results indicates that horizontal coding takes place with either horizontal or vertical effectors, whereas vertical coding takes place only when vertical effectors are used. 相似文献

A field study (n = 61) was performed in a Via Ferrata to explore how affective response influences time perception during an arousing activity in a real‐life setting (passing through a 69‐m‐long, 20‐m‐high, two‐rope bridge). Two questionnaires were administered (i) at the end point of the bridge (high‐arousing condition) and (ii) close to the end of the Via Ferrata (low‐arousing condition). Participants assessed their affect (arousal, valence, and dominance) and provided retrospective (duration estimation and passage of time judgments) and prospective (to produce a subjective minute using a stopwatch) temporal judgments. The results showed that the actual performance mediated the relationship between affect and retrospective time perception measures, with the exception of dominance, which directly predicted passage of time judgments. Regarding prospective measures, an increase in arousal was parallel to shorter temporal productions. The results are discussed in terms of the emotional factors underlying time perception in ecological contexts.Copyright © 2017 John Wiley & Sons, Ltd. 相似文献

Amyotrophic lateral sclerosis (ALS), frontotemporal degeneration and Parkinson’s disease may be different expressions of the same neurodegenerative disease. However, association between ALS and parkinsonism-dementia complex (ALS-PDC) has only rarely been reported apart from the cluster detected in Guam. We report a patient presenting with ALS-PDC in whom pathological mutations/expansions were investigated. No other family members were reported to have any symptoms of a neurological condition. Our case demonstrates that ALS-PDC can occur as a sporadic disorder, even though the coexistence of the three clinical features in one patient suggests a single underlying genetic cause. It is known that genetic testing should be preferentially offered to patients with ALS who have affected first or second-degree relatives. However, this case illustrates the importance of genetic counseling for family members of patients with sporadic ALC-PDC in order to provide education on the low recurrence risk. Here, we dicuss the ethical, psychological and practical consequences for patients and their relatives. 相似文献

Little is known about cultural variation in perceptions about the age when youngsters should be regarded as competent to make decisions. This is of particular importance as research has shown the significant effect of parental influence on their children’s decision-making. A public survey of 400 adults from diverse socio-cultural backgrounds in the UK and Spain was carried out. Their attitudes regarding adolescents’ ability with regard to common areas of decision-making were assessed using case vignettes including discontinuing family traditions and religious practice. It was found that White British adults agreed for younger adolescents to make decisions about themselves compared with the other ethnic groups. High religious practice was associated with later age to make decisions. The paper argues that there is socio-cultural variation in adults’ attitudes regarding the age when youngsters should make decisions about themselves and for the need of professionals to take this into account. 相似文献

The shoal-choice test is a popular method to investigate quantity discrimination in social fish based on their spontaneous preference for the larger of two shoals. The shoal-choice test usually requires a long observation time (20–30 min), mainly because fish switch between the two shoals with low frequency, thus reducing the possibilities of comparison. This duration limits the use of the shoal-choice test for large-scale screenings. Here, we developed a new version of the shoal-choice test in which the subject was confined in a large transparent cylinder in the middle of the tank throughout the experiment to bound the minimum distance from the stimulus shoals and favour switching. We tested the new method by observing guppies (Poecilia reticulata) in a 4 versus 6 fish discrimination (experiment 1). The new method allowed for a faster assessment of the preference for the larger shoal (<5 min), resulting in potential application for large population screenings. Guppies switched five times more frequently between the two shoals and remained close to the first chosen shoal ten times less compared to experiments with the old method. In experiment 2, we found that with the new method guppies were able to discriminate up to 5 versus 6 fish, a discrimination that was not achieved with the classical method. This last result indicates that minor methodological modifications can lead to very different findings in the same species and suggests that caution should be exercised when interpreting inter-specific differences in quantitative abilities. 相似文献

Noise-masking experiments are widely used to investigate visual functions. To be useful, noise generally needs to be strong enough to noticeably impair performance, but under some conditions, noise does not impair performance even when its contrast approaches the maximal displayable limit of 100 %. To extend the usefulness of noise-masking paradigms over a wider range of conditions, the present study developed a noise with great masking strength. There are two typical ways of increasing masking strength without exceeding the limited contrast range: use binary noise instead of Gaussian noise or filter out frequencies that are not relevant to the task (i.e., which can be removed without affecting performance). The present study combined these two approaches to further increase masking strength. We show that binarizing the noise after the filtering process substantially increases the energy at frequencies within the pass-band of the filter given equated total contrast ranges. A validation experiment showed that similar performances were obtained using binarized-filtered noise and filtered noise (given equated noise energy at the frequencies within the pass-band) suggesting that the binarization operation, which substantially reduced the contrast range, had no significant impact on performance. We conclude that binarized-filtered noise (and more generally, truncated-filtered noise) can substantially increase the energy of the noise at frequencies within the pass-band. Thus, given a limited contrast range, binarized-filtered noise can display higher energy levels than Gaussian noise and thereby widen the range of conditions over which noise-masking paradigms can be useful. 相似文献

Recent research has found that people with Irritable Bowel Syndrome (IBS) and those with Inflammatory Bowel Disease (IBD)
show a relative deficit in verbal IQ, compared to their own performance IQ, and the IQ of a healthy comparison group. It has
been suggested that the elevated prevalence of left-handedness shown in previous studies investigating people with IBD is
due to compromised left-hemisphere development. This may be associated with a decrement in certain cognitive functions such
as verbal IQ. A shift in brain dominance from left to right has been found in many atopic and immunological diseases as well
as in autonomic dysfunctions. It was uncertain whether this would apply to people with IBS, a functional disorder in which
the cause or causes remain unclear. Therefore, the aim of this preliminary study was to investigate whether people with IBS
have an increased prevalence of left-handedness. It was found that there was an association between IBS and left-handedness,
showing that further research on this association both in IBS and other functional disorders (as well as on the similarities
between IBS and IBD) is warranted. 相似文献
