Therapists sometimes encounter cases of intense marital discord in which the disaffected spouse seems unable to specify the reason for his or her discontent except in the vaguest, most general terms. Such cases may be extraordinarily difficult to treat, as the disaffected partner may seem impervious to any attempt at negotiation, to the point of dissolution of the marriage. The reason for the disaffected spouse's intransigence may seem unclear to the other spouse, to the therapist, and even to herself/himself. We hypothesize an explanation for this phenomenon in terms of the disaffected partner's experience of having suffered humiliation at the hands of the other spouse and offer a plan for treatment, citing case materials. 相似文献

Two studies are reported in which electroencephalograms (EEGs) of habitual cigarette smokers and of nonsmokers were taken before and after they were required to smoke a cigarette. The EEGs were scored for incidence of EEG "driving" responses to photic stimulation, an index that appears to reflect the balance between central adrenergic and cholinergic nervous systems. The findings suggest that smokers tend to have a central autonomic balance less in favor of adrenergic functioning than do nonsmokers. Cigarette smoking may alleviate a possible central adrenergic insufficiency of smokers. These findings suggest a solution to "Nesbitt's paradox," which has reference to the fact that while nicotine is a central adrenergic stimulant, smokers describe the effect of smoking in sedational terms (i.e., as relaxing or calming). 相似文献

Ss made magnitude estimations first of the areas, then of the distances, of four circles presented at five distances within an enclosed box 9 ft long. There were three viewing situations: the box had parallel walls, converging walls, or diverging walls. The variations in perspective cues influenced the apparent distance scales: with converging and parallel walls, apparent distance grew as the 1.4 power of physical distance; with diverging walls, it grew as the .95 power. Apparent area was related to distance differently in the three conditions: with converging walls, apparent area increased with distance; with parallel and diverging walls, apparent area decreased with distance. Apparent area was thus not related to changes in physical distance as the apparent distance effects would predict. In each condition, the ratio of apparent area to apparent distance (S′/D′) was a monotonie increasing function of retinal angle θ, but the rate of growth varied among the three conditions. The failure of θ D′ to define a unique value of S′ across conditions indicates that the size-distance invariance hypothesis is inadequate to predict the outcome of this experiment. 相似文献

Performance degradations in multitasking situations have been reported frequently as a predictable effect of competition that arises from different processing demands whose hemispheric locations are too proximal. This model might be useful in explaining performance deficits in complex workplaces. To test this assertion, a laboratory study was designed to create an analogue of the processing demands required by a tactical decision-making task performed by 24 right-handed men. Vocalization, dichotic listening and decision-making performance were assessed under single- and dual-task conditions. The results were consistent with the predictions from hemispheric competition in the case of dichotic listening but not with vocalization. The results are discussed in terms of their implications for both research and systems design. 相似文献

There is emerging evidence that the performance of risk assessment instruments is weaker when used for clinical decision‐making than for research purposes. For instance, research has found lower agreement between evaluators when the risk assessments are conducted during routine practice. We examined the field interrater reliability of the Short‐Term Assessment of Risk and Treatability: Adolescent Version (START:AV). Clinicians in a Dutch secure youth care facility completed START:AV assessments as part of the treatment routine. Consistent with previous literature, interrater reliability of the items and total scores was lower than previously reported in non‐field studies. Nevertheless, moderate to good interrater reliability was found for final risk judgments on most adverse outcomes. Field studies provide insights into the actual performance of structured risk assessment in real‐world settings, exposing factors that affect reliability. This information is relevant for those who wish to implement structured risk assessment with a level of reliability that is defensible considering the high stakes. 相似文献

A characteristic feature of hearing systems is their ability to resolve both fast and subtle amplitude modulations of acoustic signals. This applies also to grasshoppers, which for mate identification rely mainly on the characteristic temporal patterns of their communication signals. Usually the signals arriving at a receiver are contaminated by various kinds of noise. In addition to extrinsic noise, intrinsic noise caused by stochastic processes within the nervous system contributes to making signal recognition a difficult task. The authors asked to what degree intrinsic noise affects temporal resolution and, particularly, the discrimination of similar acoustic signals. This study aims at exploring the neuronal basis for sexual selection, which depends on exploiting subtle differences between basically similar signals. Applying a metric, by which the similarities of spike trains can be assessed, the authors investigated how well the communication signals of different individuals of the same species could be discriminated and correctly classified based on the responses of auditory neurons. This spike train metric yields clues to the optimal temporal resolution with which spike trains should be evaluated. 相似文献
