Eleven subjects were asked to silently read slides of the letters “P” and “T,” and to view meaningless control slides similarly as they were presented visually. One-eighth-second electromyographic excerpts were sampled from the baseline and response periods. The data were then transformed into the frequency domain for inferential analyses. The mean power spectral frequencies for the response period were significantly lower than those for the base-line in the overall analysis. There were, however, no significant changes from baseline as a function of kind of stimulus (T, P, or Control) or muscle activated (lips or tongue). It was concluded that there was a generalized responding, not unique to the processing of the specific stimuli studied. Frequency analysis of EMG measures of covert behavior holds some promise of yielding unique information not available through traditional analysis procedures, but more sensitive methods than those used here would be required to demonstrate this.  相似文献

Alcohol, probably the most popular mood-altering drug, has frightening consequences when abused. Genetic factors and sociocultural influences contribute to alcoholic behavior. Study of endocrines, neurotransmitters, and neuropeptides may reveal biological markers to help identify those at risk for alcoholism. Drinking patterns are often based on the expectation of alcohol's mood-altering quality. The focus of treatment has expanded to include not only drinking behavior but also emotional, social, and vocational adjustment. Controlled drinking has proved effective for some, so that complete abstinence is no longer the sole goal of therapy. Behavioral, martial, group and individual, outpatient and inpatient therapy, and drugs as adjuncts, all help some alcoholics, but none is a cure for all. Answers still lag behind questions but researchers have registered some advances that challenge therapists to enlarge therapeutic approaches to fit the multifaceted picture of alcoholism.  相似文献

The purpose of this work is to explore the phenomenon of negativism and the analyst's response to it during the course of analytic work with a patient in whom negativism is a central behavioral pattern. Melville's short story, "Bartleby the Scrivener," describing in telling detail the response of a sympathetic lawyer to profound and pervasive negativism in his legal scribe, is discussed as a literary analogy to the analyst-analysand dyad. Aspects of the concept of negativism within psychoanalysis are discussed. The potential usefulness of understanding certain unexpected countertransference responses to pervasive negativism is explored, as this is a relatively neglected area of psychoanalytic technique. A case is presented describing the analysis of a patient whose character, like Bartleby's, is a mixture of profound negativism along with schizoid, obsessional, and masochistic elements.  相似文献
