ResumenEl objetivo de este trabajo es estudiar la acción del efecto placebo en el tratamiento de la cefalea mediante biofeedback EMG. Un total de 22 pacientes de cefalea fueron asignados a tres condiciones experimentales: a) biofeedback EMG placebo con control interno; b) biofeedback EMG placebo con control externo; y c) biofeedback EMG real. Los resultados señalan que el biofeedback EMG placebo es tan eficaz como el real para reducir la frecuencia de la cefalea. Se discuten, por último, las distintas variables medidas en el estudio para determinar la naturaleza y eficacia del efecto placebo. 相似文献

The Multi-Center Dilemma Project is a collaborative research endeavour aimed at determining the role of dilemmas--a kind of cognitive conflict, detected by using an adaptation of Kelly's Repertory Grid Technique--in a variety of clinical conditions. Implicative dilemmas appear in one third of the non-clinical group (n = 321) and in about half of the clinical group (n = 286), the latter having a proportion of dilemmas that doubles that of the non-clinical sample. Within the clinical group, we studied 87 subjects, after completing a psychotherapy process, and found that therapy helps to dissolve those dilemmas. We also studied, independently, a group of subjects diagnosed with social phobia (n = 13) and a group diagnosed with irritable bowel syndrome (n = 13) in comparison to non-clinical groups. In both health related problems, dilemmas seem to be quite relevant. Altogether, these studies, though preliminary (and with a small group size in some cases), yield a promising perspective to the unexplored area of the role of cognitive conflicts as an issue to consider when trying to understand some clinical conditions, as well as a focus to be dealt with in psychotherapy when dilemmas are identified. 相似文献

Social learning of optimal responding and producer-scrounger strategies in flocks of pigeons. This experiment evaluated the effect of varying the effort required in order to access food upon the acquisition of a novel response, and upon utilizing producer-scrounger strategies, in flocks of pigeons exposed to an expert conspecific. Flocks of na?ve observers were exposed to a pigeon trained to open the seals on food deposits. The colors of the seals were correlated with differing required efforts. Later, the trained pigeon was removed while the color-effort correlation was maintained. The results showed that the observers acquired the response of opening the seals and that they executed it discriminatingly, responding in a greater proportion to the color that signaled the least required effort. They also assumed the roles of both producers and scroungers, which varied as a function of the composition of the group. The data obtained are congruent with prior findings regarding social learning, and also with the concepts proposed by the optimal foraging theory. 相似文献

This study examines the values held by mothers in Japan, Puerto Rico and the U.S. Mainland for their handicapped and nonhandicapped preschoolers in the contexts of home and school. In order to study values, mothers from the three cultures were asked to rank twelve value items relating to four value areas: physical, intrapersonal, interpersonal, and sociocultural. The value rankings were different in the three cultures and depended upon the home and school contexts. The presence of a diagnosed orthopedic and/or neurological impairment in the child had no overall effect on value ratings but did interact with culture and context to influence mothers' values. 相似文献

This theoretical paper sets the stage for subsequent experimental reports on mobility and immobility in the Arkansas Line of Nervous Pointer dogs as contrasted with kennel mates of the normal line. Exactly opposite to the normal animals, the nervous dogs show marked inhibition of heart rate and musculoskeletal responses to man, including reduced ambulation and durable immobility following inversion and brief manual restraint in an open sling. The sling immobility of the nervous dogs (which may not differ basically from their freezing in upright position) might be designated as “tonic immobility” (TI). We hypothesize that such immobility, common in laboratory and natural conditions in many species, should be divided into two classes: hypotonic (cataleptic) and hypertonic (catatonic). We provide examples of such behaviors, particularly in man and dog, and cursorily review TI studies of other species. Neurophysiologic and neurochemical studies which bear on possible immobility mechanisms are briefly noted. We suggest that inconsistencies in reported concommitants of TI might result from failure to discriminate between types of behavioral responses. 相似文献

Studies of behavioral traits of the “Arkansas Line of nervous pointer dogs” are well documented (Murphreeet al., 1969). Demonstrations of drug effects on these traits, as measured on the standardized behavior test and expressed as “Morbidity Score,” have been disappointing, despite other evidence of effectiveness of drug treatments such as modification of operant performance (Murphreeet al. 1974c). A simple reproducible test with high interrater reliability is presented here. Subjects were nine nervous dogs that received placebo, pimozide, and chlordiazepoxide in a double-blind crossover design. Both drugs significantly attenuated “human avoidance,” a nervous trait. Placebo had no effect. The chlordiazepoxide effect was maximal on the first day of administration, returning to baseline three to four days after the last dose. The pimozide maximal effect was on day 4, with return to baseline six to nine days after the last dose. In addition to the aberrant behavior of the nervous pointer, hyperresponsiveness to dopaminergic stimulation and increased levels of L-DOPA in the cisternal spinal fluid were observed. 相似文献

This paper is placed in the linguistic and sociocultural context of Eastern Aragon, a region of Spain where two contact languages (Spanish and Catalan) coexist in an unbalanced situation favoring Spanish. The research was prompted by the regulation for the teaching of Catalan in that area, by means of the Cooperation Agreement signed by the Spanish Educational Ministry (MEC) and the local autonomous Cultural and Educational Department of the Diputación General de Aragon in November 1986. A comparative analysis is made between Eastern Aragon students' linguistic competence in Catalan and Spanish; a further comparison is established between these students and others living in bilingual Catalonia and in monolingual Aragon. We conclude by pointing out that the Linguistic Interdependence Hypothesis accounts for the results obtained in the study. 相似文献
