Thorough reexamination of 70 patients in a long-term psychiatric ward led to partial revision of the diagnoses. Classified on the basis of Leohards's differential diagnostics, the large proportion of schizophrenics has dropped by over a third from 78% to 47%. Half of the 22 psychosis originally considered to be schizophrenia proved to be curable phasic and cycloid psychoses which had previously been overlooked and the other half were mental disturbances caused by brain-organic damage. A third of the chronic mental illnesses were found to be rooted in somatic brain lesions. 相似文献

The present study tested derivations from social learning theory on the disinhibition of aggression through processes that weaken self-deterring consequences to injurious conduct. Subjects were provided with opportunities to behave punitively under diffused or personalized responsibility toward groups that were characterized in either humanized, neutral, or dehumanized terms. Both dehumanization and lessened personal responsibility enhanced aggressiveness, with dehumanization serving as the more potent disinhibitor. Escalation of aggression under conditions of dehumanization was especially marked when punitiveness was dysfunctional in effecting desired changes. The uniformly low level of aggression directed toward humanized groups, regardless of variations in responsibility and instrumentality of the conduct, attested to the power of humanization to counteract punitiveness. Results of supplementary measures are consistent with the postulated relationship between self-disinhibiting processes and punitiveness. Dehumanization fostered self-absolving justifications that were in turn associated with increased punitiveness. Findings on the internal concomitants of behavior performed under different levels of responsibility suggest that reducing personal responsibility heightens aggressiveness more through social than personal sources of disinhibition. 相似文献

Auditory thresholds have been determined for the goldfish by six groups of workers and the data in the experiments varied by as much as 20–30 dB. In order to isolate the basis for this variability, auditory thresholds were determined using conditioned suppression of respiration and method of limits. These thresholds were very similar to those obtained with avoidance conditioning and a tracking method for threshold determination. Acoustic procedures were kept constant in the two series of experiments, and it appears that wide variation in auditory thresholds for goldfish shown in different experiments is due to acoustic conditions in the experiments. 相似文献

In order to study infants' sensitivity to binocular information for depth, 11 infants, 20 to 26 weeks of age, were presented with real and stereoscopically projected virtual objects at three distances, and the infants' reaching behavior was videotaped. When the virtual object was positioned out of reach, infants tended to lean further forward and to reach less frequently than when the virtual object was positioned within reach. In addition, the proportion of reaches in which the infants patted, closed their hands, or brought their hands together was greater when the virtual object was within reach. However, no difference in the terminal location of the infants' reaches was found as a function of the virtual object's position. Examination of reaches to a near real object revealed that infants frequently did not contact the object or show appropriate hand shape or orientation. The effectiveness of the cue of retinal size and of binocular information for the depth of an object is discussed. It is concluded that 5-month-old infants are sensitive to binocular information for depth. 相似文献

After observing the sequential flashing of two lights that produced either the perception of apparent movement or the perception of the succession of two stationary lights, the presentation of the lights in the opposite direction produced the perception of a more rapid apparent movement or of a more rapid succession of the light flashes. These aftereffects suggest the presence of neural structures for the discrimination of sequential changes in spatial position which are subject to adaptation and respond with decreased sensitivity to the repetitive presentation of the two lights in a given spatial direction. The results are interpreted to support the hypothesis that the perception of apparent movement involves the excitation of specific neural mechanisms selectively responsive to sequential changes in stimulus position. An alternative hypothesis is that the perception of apparent movement involves an inference based on the separate registrations of the position of a stimulus at one point in time and the position of that stimulus at an earlier point in time. 相似文献

A combined operandum-feeder is described that eliminates the necessity of passing an electrical sensing current through S while detecting and reinforcing tongue-licking responses. A glass nozzle for dispensing liquid reinforcers is situated just above a small separation in a loop of photo-conducting Sterite tubing; licks at a tiny area below the nozzle break a light beam and are detected via a photo-resistor and associated circuitry. Data are presented from a study in which rats worked at the operandum on a mult FR 40 ext schedule; performance and records are comparable to those obtained via conventional electronic sensing. Applications of the photo-lickerandum and an associated variable-quantum reinforcing system are suggested. 相似文献

Sefl-focused attention is hypothesized to (a) intensify emotional responses; (b) diminish susceptibility to suggestion; and (c) increase the consistency of self-report and behavior. These hypotheses were tested by having 82 undergraduates varying in private self-consciousness (PrSC) listen to humorous stimuli presented either with (laugh track group) or without (no laugh track group) canned laughter. Subjects' funniness ratings and overt laughter served as dependent measures. Regression analyses revealed that PrSC and funniness ratings were negatively correlated in the laugh track group, but uncorrelated in the no laugh track group. In contrast, PrSC and overt laughter were positively correlated in both groups. The association between funniness and laughter appeared stronger in high than in low PrSC subjects. Interpreted in light of research indicating that funniness ratings represent affect-free evaluations of humor stimuli, whereas laughter represents amusement, these results suggest that self-focus (a) intensified subjects' amusement; (b) decreased the extent to which their evaluations of the stimuli were biased by canned laughter; and (c) increased the consistency between their (self-reported) cognitive and (overt behavioral) affective responses (although this finding was equivocal). 相似文献

Adult children's ratings of their parents' behaviors on the Parent-Child Relation Questionnaire II were correlated with self-reports and peer ratings of personality on the NEO Personality Inventory in a sample of 619 men and women aged 21 to 96. Individuals who reported that their parents were loving scored lower in neuroticism and higher in extraversion, openness to experience, agreeableness, and conscientiousness. Individuals, especially men, who described their parents as casual rather than demanding were lower in extraversion and conscientiousness, but higher in openness. Parental attention (i.e., spoiling) was associated with extraversion and low agreeableness. Several of these correlations were replicated when peer ratings of personality were examined. However, all the associations were modest, and several alternative explanations suggest that the correlations may exaggerate the influence of these child-rearing practices on adult personality. Parental behaviors and attitudes seem to have less effect on broad dimensions of adult personality than traditionally supposed. 相似文献
