There are 16 items in the standard MMPI group forms which are included twice. It was found that a number of computerized scoring services use only the first occurrence of repeated items in scoring the MMPI scales, whereas the handscoring templates use an arbitrary combination of the first and second occurrence of these items. Comparison of these conventions suggested a potential for significant differences in score, particularly on the Sc scale. Scoring a set of 126 MMPIs of chronic pain patients by both of these scoring conventions revealed differences of up to 10 T points on the Sc scale. It is recommended that a single scoring convention for the MMPI be adopted by psychologists. For several reasons we suggest that only the first occurrence of repeated items should be used for scoring purposes. In the absence of a single convention, comparisons between Sc scores on different protocols should not be made without first insuring that the protocols were scored in the same manner.  相似文献

The effects of 6-hydroxydopamine (6-OHDA) injected into the lateral septum in rats were investigated for spontaneous alternation behavior in a Y maze and for spatially oriented behavior in an 8-arm radial maze. The performance of the animals in these tests was assessed under two physiological states, food-satiated and food-deprived. The selective depletion of septal dopaminergic concentrations leads to behavioral disturbances in both the Y and the radial mazes. These deficits disappeared when the animals with 6-OHDA lesions were food-deprived. These results confirm other studies from our laboratory and support two conclusions. First, lesions of dopaminergic neurons lead to behavioral impairments which resemble those found after the total lesion of the structure they innervate. Second, these behavioral impairments are responsive to therapeutic treatments, manipulations of the internal or external environment, or the level of arousal, since under certain conditions a recovery of function can occur in the absence of dopaminergic neurons. These two points provide additional support for a nonspecific role for the dopaminergic neurons originating in the ventral tegmental area. These neurons could have a permissive role in the functioning of the forebrain structures they innervate.  相似文献

The use of sacrificial animal blood in the Hebrew Bible has generated much discussion. While various scholars have attempted to explain the significance of these blood rites, each of these attempts has proved problematic. The current paper employs mimetic theory to develop a more robust and plausible model for exploring biblical animal sacrifice. Using the Passover ritual as a model, I develop a model of sacrificial blood rites as pantomimes of mimetic violence. These pantomimes re-create a violent yet transformative crisis from the community's collective memory. Such rituals allow the community to enter into and re-experience the cleansing violence of a mimetic crisis, albeit in a more controlled manner. Through these pantomimes, the community attempts to appease the primitive sacred's blood lust and re-discover the divine blessing secured through the original crisis. This model may prove helpful when applied to more opaque examples of biblical blood manipulation.  相似文献

It is shown that a rational learning curve developed by Estes for paired associate learning is a special case of a more general function. The latter is the product of two functions and assumes that the discovery and fixation aspects of learning are independent. The indications are that the form of one of the functions has not been tested sharply by Estes in the paired associate learning setting.  相似文献

The “disjuncture” between level of aspiration and means of accomplishing it can create serious difficulty for the person. The function of the 2-year college in helping the student to resolve this conflict has been described as a “cooling-out” process. Essentially, it involves a running evaluation of the student's capacities, and guidance in helping him to find the educational and vocational program for which he is best suited. Several ways of facilitating this process are presented. There is need for an integrated guidance program pervading the entire institution as well as the student's career at the institution.  相似文献
