Developmentally, attitudes toward casual alcohol use and toward the abuse of alcohol should be related to the development of value content and value structure. Two studies were conducted that found this to be generally so with upper elementary schoolchildren. A negative attitude toward the abuse of alcohol was definitely related to general measures of the intemalization of those values necessary to be a part of any group as well as the rejection of acts generally considered to be deviant in our culture. Attitudes toward casual use of alcohol were also somewhat related, but not as strongly. However, alcohol attitudes were unrelated to stage of moral development or other measures of thinking processes. Some shifts across age and sex were also noted. Programs oriented toward the prevention of alcohol abuse may need to communicate the value norms of our society and can proceed without impacting attitudes toward casual alcohol use.  相似文献

This study evaluated the effectiveness of the Primary Mental Project (PMHP), a program for early detection and prevention of school adjustment problems. Pre- and postprogram assessments were done with 215 primary-grade children seen in PMHP, usig teacher ratings of problem behaviors and competencies, and child-aide ratings of problems. School mental health professionals judged educational and behavioral changes in project children during the year. Significant across-the board improvements were found on all criterion measures. Modest intercorrelations among criterion change estimates suggested that the observed changes were due to program, rather than halo, effects. PMHP children also improved significantly more than matched, retrospective controls.  相似文献

Auditory evoked responses (AER) were recorded from scalp locations over the left and right temporal regions in response to CVC words and nonsense syllables. Various components of the AER were found to vary systematically with changes in stimulus meaning. One such component reflected subcortical involvement in semantic processing. Other components reflected changes in voicing and place of articulation as well as hemisphere differences.  相似文献

Subjective sexual arousal and affective reactions of 80 college women to explicit sex films were studied in a 2 (sex guilt) × 2 (trait anxiety) × 2 (films) design. There was a decline in sexual arousal to a film of oral-genital sex and a decline in sex guilt in the present sample in comparison to a similar sample from this laboratory 8 years ago. High-sex-guilt women reported fewer genital sensations and rated themselves lower on sexual arousal during and after the films than did their counterparts less disposed to guilt over sex. High-sex-guilt women reported more affective guilt, disgust, and anxiety-fear as a consequence of viewing an explicit sex film than women below the median on sex guilt. High-trait-anxiety women reported more intense genital sensations and rated their sexual arousal as higher following the films than low-trait-anxiety women. Women above the median on trait anxiety reported more subsequent anxiety-fear and depression-distress following the films than low-scoring women. These results were discussed from the perspective of Izard's differential emotions theory, which regards anxiety as a variable pattern of fundamental emotions rather than as a functional unity.This research was supported in part by a National Science Foundation Grant to the University of Connecticut Computer Center.

In Experiment 1, pictures were presented to subjects two, five, or eight times, and subjects were asked to imagine each pciture two, five, or eight times. Subsequently, subjects estimated the number of times each picture had been presented. Their estimates of the frequency of these external events were influenced by imagination trials; this effect was greater for good imagers than for poor imagers. Experiment 2 involved a similar design in which subjects were asked either to imagine the same referent for a word or to imagine a different referent for a word on successive imagination trials. Consistency (same referent) did not increase the influence of imaginations on immediate judgments of external frequency. Thus, the results of Experiment 1 were attributed to the greater accuracy (as opposed to greater consistency) of good imagers' internal generations of the stimuli. Furthermore, variation (imagining different referents), like greater accuracy, increased the effects of imagination trials on immediate but not on delayed judgments of frequency. Possible mechanisms underlying these effects are discussed. In general, the two studies show that qualitative characteristics of completely covert generations influence their impact on estimates of the frequency of external events.  相似文献

Faster same than different judgments typically are obtained when two letters are compared. When two tones that might differ only on frequency are compared, however, same judgments typically are slower than different judgments. A uniprocessor, unidimensional model, based on Krueger's noisy-operator theory, was fitted satisfactorily to data from four published studies of tone comparison. The model predicts faster response time on different judgments because of heterogeneity of difference. Because the second tone in a pair typically may be either higher or lower in frequency than the first, there will be a greater variety of perceived difference counts on different pairs than on same pairs. As a result, a large difference count will be decisive and will lead to an immediate "different" response, because it can be produced only by a different pair, whereas a small difference count will not be so decisive because it can be produced by either a same or a different pair. Consequently, there generally will be more rechecking on same than different pairs, and thus longer RT on same pairs.  相似文献

In Experiment 1, rats were given one trial per day in a straight alley under food deprivation on half of the trials and under water deprivation on the other half. Wet mash was available in the goal box under food deprivation for Group H and under water deprivation for Group T, the other deprivation being nonrewarded for each group. After 15--18 trials both groups ran significantly faster on their rewarded than on their nonrewarded deprivation days. A third group showed that random variation of alley color retarded formation of the discrimination. A fourth group was run in a conditional discrimination in which under food deprivation wet mash was available in a black alley, nonreward in a white alley, and vice versa under water deprivation. This group took 114 trials to begin running significantly faster in their rewarded than in their nonrewarded alley under each deprivation. In Experiment 2, it was shown that prior learning about deprivation cues "blocks" learning about alley color when alley color is subsequently presented in compound with the deprivation cue but that when both alley color and deprivation cues are relevant from the start of training, the rat learns about both cues. It is suggested that previous studies have underestimated the importance of deprivation cues by using conditional discrimination designs, choice measures rather than speeds, and parameters that are not optimal for discrimination learning.  相似文献

Summary Following an abrupt shift from a therapeutic community with emphasis on group meetings to a hierarchical medical model on a mental hospital floor, disturbed patients required extensive individual nursing care. This increased work load for the nursing staff resulted in admissions having to be limited to the rare cases who needed little or no nursing care. As patients were discharged, the vacancy rate went up to approximately 20% for a week and remained high for another two weeks. Nursing staff-patient relations deteriorated.Subsequently, it was possible to resume the emphasis on the groups of a therapeutic community and to observe the contrast. The experience showed how groups can effect and support a therapeutic community. It clarified some of the mechanisms by which groups positively affected disturbed patients. Some mechanisms by which the staff, community, and group meetings favorably influenced the nursing staff-patient relationship and intrastaff communications became clear also.  相似文献
