Temporal integration of patterned stimuli was investigated by introducing an interstimulus interval (ISI) between brief exposures of two matrices of illuminated squares. These matrices were identical except for their spatial displacement, arranged such that they could be superimposed to yield either horizontal or vertical stripes. Choice reaction times to the composite stripe orientation were a progressively increasing function of ISI, suggesting some integration over an ISI range in excess of 224 msec. Similar functions were obtained with both regular and irregular order of ISI presentation. The results from an additional experiment employing an extraneous warning signal discounted the possibility that preparatory factors developing over the ISI were responsible for the obtained reaction time functions. 相似文献

Displays of eight capital letters were presented in a circular arrangement around a central fixation point at tachistoscopic durations. Under different experimental conditions, one or two indicators, presented either 250 msec before, simultaneously with, or after the display, designated the letters that S was to report. The arrangement of conditions permitted inferences as to the order in 相似文献

The purposes of the present experiment were to provide information on rate of information processing in visual perception and to determine the degree to which the “sequential blanking” effect found by Mayzner. Tresselt, and Cohen (1966) constituted a limitation on rapid sequential input rates. A 10-channel tachisto scope was employed that permitted controlled durations of each of the 10 channels and the 9 inter channel intervals. The S’s task was one of visual search or detection in which he searched for a target letter among noise letters. A temporal interval forced-choice procedure was used. In addition to varying the rate at which letters were sequentially presented, various irregular temporal spatial orders of presentation of the letter sequences were employed and the direction and orientation of the display in the visual field was varied as was also the spacing between adjacent stimuli. No evidence of “sequential blanking” was found either in terms of the detection criterion or in the Ss’ phenomenal reports. Detection performance was as good at a rate of 2 1/2 msec per letter as it was at a rate of 30 msec per letter. 相似文献

Research since the 1960s has consistently found that lay volunteers are better at helping suicidal callers than professionals. Yet, professional degrees are increasingly becoming requirements for helpline workers. In our first study, we conducted post hoc comparisons of U.S. helplines with all professional paid staff, all lay volunteers, and a mix of both, using silent monitoring and standardized assessments of 1,431 calls. The volunteer centers more often conducted risk assessments, had more empathy, were more respectful of callers, and had significantly better call outcome ratings. A second study of five Quebec suicide prevention centers used silent monitoring to compare telephone help in 1,206 calls answered by 90 volunteers and 39 paid staff. Results indicate no significant differences between the volunteers and paid employees on outcome variables. However, volunteers and paid staff with over 140 hours of call experience had significantly better outcomes. Unlike the United States, Quebec paid employees were not required to have advanced professional degrees. We conclude from these results and previous research that there is no justification for requiring that suicide prevention helpline workers be mental health professionals. In fact, the evidence to date indicates that professionals may be less effective in providing telephone help to suicidal individuals when compared to trained lay volunteers. 相似文献

This paper describes an investigation into the function of child-directed speech (CDS) across development. In the first experiment, 10–21-month-olds were presented with familiar words in CDS and trained on novel words in CDS or adult-directed speech (ADS). All children preferred the matching display for familiar words. However, only older toddlers in the CDS condition preferred the matching display for novel words. In Experiment 2, children 3–6 years of age were presented with a sentence comprehension task in CDS or ADS. Older children performed better overall than younger children with 5- and 6-year-olds performing above chance regardless of speech condition, while 3- and 4-year-olds only performed above chance when the sentences were presented in CDS. These findings provide support for the theory that CDS is most effective at the beginning of acquisition for particular constructions (e.g. vocabulary acquisition, syntactic comprehension) rather than at a particular age or for a particular task. 相似文献

Although counselors receive training in both diagnosis and cultural foundations of human behavior, little literature or research integrates these 2 areas in order to facilitate culturally sensitive diagnostic practices. The authors attempt to rectify that lack by providing a review of the literature on the controversies associated with traditional diagnosis of cultural groups that differ from the dominant culture. Practical guidelines for culturally sensitive diagnosis are provided. 相似文献

The manifold functions of a supervisor in following the course of complex processes together with the trainee, are: ? to keep the goals of the supervision in view, ? to establish a teaching alliance and to support the wish and ambitions of the candidate to learn, ? to build a platform for the complex interactions with the trainee with regard to the dynamics of the training situation and keeping in mind the institutional influences, ? to lay down the setting for the work, ? to explore and to reflect how transference and counter-transference influence the interaction between patient and analyst as well as between trainee and supervisor, ? to examine these interactions together focussing continuously on the interaction between candidate and patient, and to encourage the candidate to do the same on his own, ? to continuously formulate hypotheses about the core conflict, the transference phenomena and resistance of the patient, ? to explore and reflect on the cooperative work. 相似文献

Research on vulnerability factors among ethnic groups, independent of primary psychiatric diagnosis, may help to identify groups at risk of suicidal behavior. French African Caribbean general psychiatric patients (N = 362) were recruited consecutively and independently of the primary psychiatric diagnosis. Demographic and clinical characteristics and lifetime history of suicide attempts were recorded. Sixty‐five patients (18%) had a history of at least one suicide attempt. Presence of professional qualifications, children, poor social contacts, treatment with benzodiazepine at inclusion, and poor treatment compliance were all associated with a lifetime history of suicide attempts. 相似文献
