Pettigrew's (1958) hypothesis that quality of psychological adjustment is partly a function of the fit between a person's political values and those of the surrounding social milieu was tested using student samples from Queensland and South Australia. The measures of psychological adjustment were two factors of locus of control (political and general) and general life satisfaction. As predicted, in the Queensland sample conservatism was positively associated with higher general life satisfaction while this correlation was reversed for the South Australian sample. Results for the locus of control measures failed to support the hypothesis. The results provided support for the general Person/Environment fit model and indicated the feasibility and value of studying regional differences in Australia. 相似文献

Two experiments were carried out in which reaction time for identification of words in sets of four was measured. The words were of three letters, with dichotomous variation of the first and third letters, in either upper- or lowercase, with letters chosen to give maximum variation in word configuration in lowercase. Four types of display were used, differing in size and masking. In Experiment 1, the words were easy to identify in uppercase as well as in lowercase, because the letters were easily discriminable in either case, and the results showed no advantage to lowercase words at any level of degradation. In Experiment 2, the letters were more difficult to discriminate in uppercase, and with the most severe degradation, the words in lowercase were identified more rapidly than those in uppercase. Thus the reaction time results showed an advantage of the configural properties available in lowercase only with words difficult to identify in uppercase and with extreme amounts of degradation. Error analyses of both experiments showed that errors were made to individual letters, not on the basis of the configuration, for words in both cases. It is concluded that letter processing occurs even when there is evidence for the use of configural information, thus implying a predominant role of letter perception in word identification. Some reservation is expressed whether whole-word configuration is the only pertinent configural property and whether the results from such simple identification tasks are appropriate to an understanding of natural reading. 相似文献

Previous results have implied that pattern goodness, as defined by rotation/reflection equivalence set size, is a determinant of encoding time. A direct test of this implication was made via a discrete RT task using good and poor dot patterns in a two-stimulus discrimination. The following discrimination conditions were used: (1) good vs good; (2) poor vs poor; and (3) good vs poor. Overall RTs for Conditions 1 and 3 were equal, but each was significantly faster than Condition 2. In the first two conditions, there was no difference in RT within pairs and no consistent transitive ordering of the patterns. In Condition 3, however, the good pattern consistently produced the smaller RT. These results indicate that patterns of equal goodness are equally encodable, and the better the pattern, the faster it is encoded. In addition, there was evidence that pattern similarity affects RT. 相似文献

Interobject visual similarity is often measured by the time that subjects require to say that two objects are not identical, with long RTs indicating high similarity. In Experiment 1, using a complete set of uppercase alphabetic stimuli, we show: (1) RTs correlate strongly with direct ratings of visual similarity. (2) Stimuli that are similar as measured by RT or by direct judgment have the same profile of similarity to all other stimuli in the set as measured by correlational analysis. (3) The order in which the stimuli are compared has only a small effect on measured similarity. All of these results indicate desirable properties of any measure of similarity.Intraobject similarity is a concept pertinent to the relation of an object to itself. In Experiments 1 and 2 we show: (1) All letters are not equally similar to themselves, since RT for the “same” response is different for different letters. (2) The relation between RT and intraobject similarity is opposite to that for interobject similarity, with short RTs indicating high intraobject similarity. (3) Even though intraobject similarities differ, each letter is more similar to itself than to any other letter in the set. We discuss the implications of these results in terms of assumed proximity constraints underlying similarity data. 相似文献

In a replication of Cooper and Shepard's (1975) study of hand recognition, it was found that individual differences in imagery ability had a significant influence on reaction times to such stimuli (Experiment 1). However, it was found (Experiment 2) that individual difference effects were only seen if prior instructions to use imagery were given to the subjects. 相似文献

Two qualitatively different sounds were used to generate256 different sequences of length8, and these sequences were presented to Ss at a rate of two stimuli per second. These sequences, when repeatedcontinuously,canbe grouped into20 fundame ntally different patterns, each having either2, 4, or8 distinguishably different starting points. Ss were required to listen and to be gin responding (with telegraph keys) in synchrony to the patterns when they were able. The point at which they began responding, the delay before responding, and errors after beginning responding were measured. The response uncertainty (variability of point of response for a given pattern), average delay, and average errors are all highly correlated, indicating that patterns which are easily organized are those which have few alternative modes of organization, and thus can be considered as simple, or good in the Gestalt sense. 相似文献

Undergraduates (N = 385) watched a 2-hr, videotaped, mock trial of a child sexual abuse case. The child testified in open court, with a barrier between the child and the defendant, or via closed circuit television. Students enacted the role of a juror, sibling of the defendant, or sibling of the mother of the victim. The judge either did or did not warn jurors that the barrier or video should not be considered evidence of the defendant's guilt. Use of the barrier or video did not influence guilty votes, the credibility of witnesses, nor the perceived fairness of the trial for jurors. Siblings of the defendant perceived these procedures to be biased and their use as unfair. Increased publicity about the use of barriers and closed-circuit television when children testify is recommended to reduce objections to these procedures. 相似文献

The relationship of structural ischemic brain damage to neurobehavioural deficit: the effect of postischemic MK-801 总被引:2,自引:0,他引:2
Global cerebral ischemia is well known to cause neuronal necrosis in selectively vulnerable sectors of the hippocampus. Since the hippocampus of the rat is involved in spatial navigation, learning, and memory, selective deficits in these abilities may arise from ischemic brain damage. Previous studies have shown (a) a detectable neurobehavioural deficit due to ischemic brain damage limited to half of the CA1 sector of the hippocampus and (b) a reduction of ischemic neuronal necrosis with the noncompetitive N-methyl-D-Aspartate (NMDA) antagonist MK-801. This study was designed to determine the relationship between the improvement in structural brain damage in postischemically treated rats and any improvement in neurobehavioural performance, using a learning-set water task. Seventeen male Wistar rats received 10.5 min of forebrain ischemia induced by carotid clamping and hypotension. Brain temperature was estimated with probes in the temporalis muscle. Ten of these animals received no therapy (controls), and seven animals received 5 mg/kg MK-801 iv, 20 min postischemia. Six additional rats underwent a sham operation. Postischemic hypothermia was prevented with heating lamps. Four controls and one MK-801 treated animal died. The survivors were then tested on a place learning-set task in a swimming pool paradigm, and quantitative histopathologic analysis of their entire brains was done. The learning-set task revealed defects in spatial navigation, reflected as increased errors and latency in the performance of the untreated control rats. The performance of the MK-801 treated group progressively approached that of sham-operated rats over the course of testing and was significantly better than controls. Importantly, no long-term detrimental effect of MK-801 on the learning-set task performance was seen. Quantitative neuropathology revealed significantly less damage in the MK-801 treated group in all major brain regions. In the hippocampus, MK-801 treated animals showed hippocampal damage limited to the vulnerable portion of the pyramidal cell band comprising 48.8% of the CA1 pyramidal cells, as opposed to 72.4% in untreated controls. Extra-hippocampal damage was evident only in untreated control animals. MK-801 totally prevented neuronal necrosis in both the cerebral cortex and striatum and also prevented infarction in the neocortex and thalamus. Three conclusions emerge from the study. First, postischemic MK-801 mitigates structural brain damage in several brain regions in the absence of concomitant hypothermia. Second, neurobehavioural performance appears to be improved by MK-801 when performance trends are examined, but is somewhat less sensitive than quantitated histopathology due to compounding interanimal variation in performance abilities.(ABSTRACT TRUNCATED AT 400 WORDS) 相似文献
