An experiment was conducted on the hypothesis that the differences in personality and behaviour of various groups of psychiatric patients would be reflected in a serial visuo-motor task. The patients' errors, blocks and RT variability were ascertained and significant differences emerged between the groups. All of the experimental groups—chronic schizophrenic, brain-injured psychotics, brain-injured non-psychotics—differed from the disturbed, non-psychotic control group on all of the variables tested. A group of paranoid schizophrenic patients, however, differed from the controls in only two respects, i.e. variability and number of responses per minute. The paranoid schizophrenic group produced a strikingly different performance from that of the chronic schizophrenic group. The latter group exceeded all other groups in both the frequency and duration of blocks. 相似文献

We are standing on the edge of a new era in the development of school psychology programs and training. It is expected that if such training is related to high level certification standards, there will be a smoother course for both training programs, state certifying agencies, and those certified. This cannot be left merely to chance, or to the whims of state governing bodies. Universities polled have generally played an important part in setting high standards in the past, although some have merely imitated lower existing state standards. Universities, assisted by the suggested certification standards of Division 16, should be active in presenting their point of view at the local level regarding future standards. 相似文献

Resource allocation during spoken discourse processing: Effects of age and passage difficulty as revealed by self-paced listening 总被引:2,自引:0,他引:2
The allocation of processing resources during spoken discourse comprehension was studied in a manner analogous to self-paced reading using the auditory moving window technique (Ferreira, Henderson, Anes, Weeks, & McFarlane, 1996). Young and older participants listened to spoken passages in a self-paced segment-by-segment fashion. In Experiment 1, we examined the influence of speech rate and passage complexity on discourse encoding and recall performance. In Experiment 2, we examined the influence of speech rate and presentation mode (self-paced vs. full-passage presentation) on recall performance. Results suggest that diminished memory performance in the older adult group relative to the young adult group is attributable to age-related differences in how resources were allocated during the initial encoding of the spoken discourse. 相似文献

When asked to recall the words from a just-presented target list, subjects occasionally recall words that were not on the list. These intrusions either appeared on earlier lists (prior-list intrusions, or PLIs) or had not appeared over the course of the experiment (extra-list intrusions). The authors examined the factors that elicit PLIs in free recall. A reanalysis of earlier studies revealed that PLIs tend to come from semantic associates as well as from recently studied lists, with the rate of PLIs decreasing sharply with list recency. The authors report 3 new experiments in which some items in a given list also appeared on earlier lists. Although repetition enhanced recall of list items, subjects were significantly more likely to make PLIs following the recall of repeated items, suggesting that temporal associations formed in earlier lists can induce recall errors. The authors interpret this finding as evidence for the interacting roles of associative and contextual retrieval processes in recall. Although contextual information helps to focus recall on words in the target list, it does not form an impermeable boundary between current- and prior-list experiences. 相似文献

Factors predicting the use of technology: findings from the Center for Research and Education on Aging and Technology Enhancement (CREATE) 总被引:4,自引:0,他引:4

The successful adoption of technology is becoming increasingly important to functional independence. The present article reports findings from the Center for Research and Education on Aging and Technology Enhancement (CREATE) on the use of technology among community-dwelling adults. The sample included 1,204 individuals ranging in age from 18-91 years. All participants completed a battery that included measures of demographic characteristics, self-rated health, experience with technology, attitudes toward computers, and component cognitive abilities. Findings indicate that the older adults were less likely than younger adults to use technology in general, computers, and the World Wide Web. The results also indicate that computer anxiety, fluid intelligence, and crystallized intelligence were important predictors of the use of technology. The relationship between age and adoption of technology was mediated by cognitive abilities, computer self-efficacy, and computer anxiety. These findings are discussed in terms of training strategies to promote technology adoption. 相似文献

Inhibition of return (IOR) has long been viewed as a foraging facilitator in visual search. We investigated the contribution
of IOR in a task that approximates natural foraging more closely than typical visual search tasks. Participants in a fully
immersive virtual reality environment manually searched an array of leaves for a hidden piece of fruit, using a wand to select
and examine each leaf location. Search was slower than in typical IOR paradigms, taking seconds instead of a few hundred milliseconds.
Participants also made a speeded response when they detected a flashing leaf that either was or was not in a previously searched
location. Responses were slower when the flashing leaf was in a previously searched location than when it was in an unvisited
location. These results generalize IOR to an approximation of a naturalistic visual search setting and support the hypothesis
that IOR can facilitate foraging. The experiment also constitutes the first use of a fully immersive virtual reality display
in the study of IOR. 相似文献

To study the social-emotional development of triplets, 23 sets of triplets, 23 sets of twins, and 23 singleton infants (N=138) were followed from birth to 2 years. Maternal depression and social support were assessed in the postpartum period, mother-infant and father-infant interaction and the home environment were observed at 3 months, a separation-reunion episode and a maternal interview were conducted at 12 months, and infant behavior problems were evaluated at 24 months. Lower parent-infant synchrony was observed for triplets. Triplets showed less distress during maternal separation and less approach at reunion. Mothers reported lower adjustment and differentiation among siblings for triplets than for twins. Higher internalizing problems were reported for triplets, and the triplet with intrauterine growth retardation showed the poorest outcomes. Behavior problems were predicted by medical risk, maternal depression, parent-infant synchrony, infant approach, and mother adjustment. Discussion focuses on developmental risk when the exclusivity of the parent-infant relationship is compromised. 相似文献

Tests of the null hypothesis for comparisons involving sample means use the t test when the conditions of the z test cannot be met. The 2 tests have different rationales and can lead to different conclusions regarding significance. In the present study, the authors compared the properties of t and z in simulation runs. The differences in the results are a result of fluctuations in the t test sample variances that do not exist in the z test, and those differences lead to differences in designating the significance of comparisons. 相似文献
