Sixteen student volunteers were administered a placebo and 50 mg. of chlorpromazine in tablet form, on separate occasions,
two hours before testing. The three tests measured dichotic listening performance, lateral eye movements while answering questions
about spatial location and verbal meaning, and lateralized facial expression while relating pleasant and unpleasant life incidents.
Results showed that chlorpromazine increased the number of trials showing an ear advantage in dichotic listening. Chlorpromazine
reduced lateral and increased vertical eye movements in response to the questions about spatial location and verbal meaning.
Under the placebo both negative and positive emotions were expressed more in the left face. Although chlorpromazine did not
affect this lateralization of negative emotions, the expression of positive emotions occurred equally often on the two sides
of the face under chlorpromazine. Results may be related to an effect of chlorpromazine on the asymmetrical dopamine pathways
of the brain. It is suggested that the findings may be related to a left hemisphere deficit in schizophrenia. 相似文献

A social skills training program was evaluated with emotionally disturbed adolescent inpatients. The targeted social skills required an action or reaction within six skill areas. The program was adapted from a commercially available social skills training game that features the use of response specific feedback, self-monitoring, individualized reinforcers, and individualized performance criteria. A peer conducted the baseline and posttraining sessions while the training was conducted by an adult who had no previous interactive history with the subjects. A multiple baseline design across groups demonstrated that the program increased appropriate responding in all skill areas and that these effects generalized during the posttraining peer conducted sessions. A generalization test indicated that the subjects used their newly learned skills with a novel adult outside the training setting. The program appears quite applicable to emotionally disturbed adolescents since it targets skills in a variety of areas and employs standardized procedures to enhance replicability. 相似文献

The present study examined observers’ ability to discriminate canonical and dynamically anomalous collisions that were presented in either frictionless or frictional systems. Whereas previous research has provided qualitative demonstrations that dynamic information can be extracted from visual events, the current study provides a parametric assessment of observers’ sensitivity to dynamic invariants. Our findings indicate that observers are competent when viewing both familiar, terrestrial (frictional) systems and unfamiliar but computationally simpler, 0-G (frictionless) systems. Thus, our sensitivity to these dynamic invariants in visual events is robust in natural systems whose dynamic properties differ from those of the environment in which we evolved and developed. 相似文献

A technique is described in which line-drawn pictures can be rapidly interlaced, allowing for sequential part presentation or tachistoscopic presentation on the Apple II. This is accomplished using a two-stage process in which the pictorial stimuli are converted into machine code data files and then used to create a rapidly changing display consisting of two or more line drawings. The latter stage could be accomplished in less than 2 msec but is limited by the frame time of the monitor (17–20 msec). 相似文献

Normative data are presented for the probability of successfully completing 192 single-solution word fragments. Normative data on the familiarity of college students with the solution words are also given, along with estimates of word frequency from existing norms. Regression analyses were performed in order to predict fragment completion difficulty from familiarity, frequency, and several structural characteristics of the fragments. Familiarity, whether or not first and/or last letters appeared in the fragment, and the ratio of letters to missing letters in the fragment were included in the regression equation as significant predictors of difficulty for this fragment set. 相似文献

The effects of lactate infusion on subjective mood change were studied in two differently instructed groups, in a double-blind, placebo-controlled, cross-over study. Ss who were told that infusions would produce anxiety reported a significant change in the expected direction after lactate but not after glucose. Ss who were told that infusions would produce a state of pleasant excitement showed no change after either infusion. The possible role of cognitive parameters in experimentally-induced anxiety is discussed. 相似文献
