This paper attempts to define the concept of placebo as it is used in the clinical context The author claims that X is a placebo
if and only if X has such a property dp, that whenever in a therapeutic situation T a stimulus S appears, then in attending conditions A, it will cause a beneficial
reaction R in the patient. Formally, the same structure may be used to define any pharmacologically active drug. The main
difference between the drug and a placebo is in the range of possible substitutions for X and the property d. For the active
drug there is only one possible substitution for X and property d and it can be scientifically explained why, and how the
drug works. In the case of a placebo a set of possible substitutions for X and d is open, and so far it is impossible to offer
any scientifically valid explanation of the action mechanism of placebo. 相似文献

The Zuckerman Sensation-seeking Scale (SSS) was administered to 190 men and 197 women, who were also asked to choose 5 pictures out of a group of 21. Seven of these pictures had been rated as emotionally positive, 7 as emotionally neutral and 7 as emotionally negative. Choices of the high and low sensation-seeking groups were compared, and it was found that the high sensation-seekers had a stronger preference for the hegative stimuli than the lows, and the low sensation-seekers had a stronger preference for the positive stimuli than the highs. The results are discussed in terms of optimum level of arousal. 相似文献

Thirty happily married and thirty unhappily married couples were examined by means of the MPI questionnaire to test the hypothesis that emotional instability impaired satisfaction in marriage. Unhappily married partners were very significantly higher on neuroticism than happily married partners, but there were no differences in extraversion/introversion. The data suggest that the high neuroticism of the unhappily married partners antedates their marriage. 相似文献

The author has tested the hypothesis that psychoticism, as described in Eysenck's theory of personality, is related to marriage outcome. Thirty happy and 30 unhappy couples answered the Eysencks' EPQ questionnaire. The unhappy husbands and unhappy wives scored significantly higher on the P scale than their happy counterparts respectively. The results suggest that psychoticism (like neuroticism) may impair the marriage satisfaction. In addition, happily married spouses show greater similarity with respect to personality than do unhappily married spouses. Thus the results support the likeness and go counter to the complementaries theories of marital satisfaction. 相似文献
