The Rorschach test was used as an experiment of perception to analyze (external and internal) stimulus-response and individual response specificity of electrodermal orienting response OR (skin conductance response SCR) to presentations of unstructured material. On a sample of 84 subjects (medical students and colleagues of the medical department) the partial effects of "card" (external stimulus), "affective content of the signification" (internal stimulus), and "subject" on the (range-corrected) electrodermal OR were analyzed. The variance-analytic model was highly significant. The highly significant card effect with a physiological variance component of about 9% was interpreted as a "novelty" component of the electrodermal OR. The examined response characteristic also had a significant effect on the electrodermal OR with a physiological variance component of about 1%. Yet the determining variable was not the affective content of the signification, but rather the complexity of the (affective) signification. This result was discussed in terms of information processing and conflict theory. The important interindividual OR variance of nearly 40% supported the concept of the individual specificity of physiological response. 相似文献

To obtain evidence about the relationship between spontaneous EEG activity and mental activity, an experiment was designed and executed with EEG recordings during a concept-learning task. We varied task performance (self-paced vs. machine-paced) and distinguished different stages of information processing during task performance. Using factor analysis calculated on all spectral coefficients, we found two orthogonal variables in the clinical alpha band. Alpha 2 power (10.5-12 Hz) seems to reflect the overall processing demands imposed on the individuals. Furthermore, there are different EEG frequency patterns during perceptual-central- compared with response-related processing as well as during processing of positive vs. negative feedback. The results suggest using (1) conservative procedures in hypothesis testing and (2) procedures to reduce between subject variability (a posteriori defined frequency variables, relative power values, scaling of reaction values) in further studies relating EEG activity to mental activity during task performance. 相似文献

Feelings of existential guilt are assumed to depend on the perception of a causal relationship between one's own behavior or (privileged) situation and the disadvantages of others. By contrast, pity should not depend on such perceptions. This hypothesis, which has been supported so far only by correlational studies, was tested experimentally. Eighty students were shown a film about a developing country. The film was provided with four different comments, each representing one experimental condition (between-subjects design). Experimental factors were "amount of misery of the people shown" and "subject's responsibility for these peoples' conditions of life". As expected, subjects in the condition "misery and responsibility" reported higher feelings of guilt, though no more pity than subjects in the remaining three treatment conditions (experiment 1, n = 40). This mean difference, however, was statistically significant for men only. Contrary to our theoretical expectations--and to finding from other experiments on vicarious reparation--the induction of guilt had no effect on willingness to help a third party (experiment 2, n = 40). Possible reasons for this unexpected finding are suggested. 相似文献
