In a residential research ward setting six volunteer chronic alcoholics were given daily access to 17 alcoholic drinks provided that a minimum of 40 min elapsed between receiving successive drinks. Each drink contained 1 oz 95-proof ethanol in orange juice. During baseline phases subjects were free to drink and socialize on the dayroom. However, during social time-out phases subjects were not permitted to socialize for the 40 min period following receipt of each drink. This contingent social time-out manipulation was systematically replicated across three conditions which varied with respect to the number of non-contingent ward privileges available. The results show that contingent social time-out suppressed drinking; and its effectiveness depended directly upon the conditions of available privileges. Within individual subjects, contingent time-out was increasingly effective in suppressing drinking as the available privileges were increasingly restricted. 相似文献

The generalization of newly learned behaviors to different settings on the part of an autistic child and his parents was investigated by means of a multiple baseline design. Contingency management techniques were taught to the parents while they interacted with their child in a training apartment equipped with observation facilities. In order to assess whether the parents generalized the use of these techniques, data were gathered at their own home. Data were also gathered in the child's school in order to ascertain whether changes brought about in the child's behavior in the training apartment generalized to the school situation. It was concluded that the child's behavior was responsive to the contingencies of each particular environment. Generalization did not occur until the contingencies and stimulus cues were specifically designed to promote a change in behavior in each setting. 相似文献

A circuit is described for interfacing response keys and other discrete inputs from psychological apparatus to a computer. Some of the unique features are: high noise immunity, the ability to transmit data over long distances, and electrical protection of the computer from accidental and potentially catastrophic high voltage inputs. 相似文献

The study investigated diurnal patterns of depressed mood in a sample of normal subjects. In all, 105 college undergraduates were followed for a period of 10 days, using a self-administered psychological diary. Eighty-four percent of the days in which feelings of depressed mood were reported involved some type of mood swing. The most frequent pattern of mood shift was a pattern of gradually increasing depressed mood, reaching its peak in the evening. Persons who reported days of constant depressed mood reported higher levels of physical symptoms and less pleasure in social interactions than persons who reported only depressed days involving mood swing. 相似文献

An event-related potential (ERP) probe was used to examine various models of ambiguous sentence processing. ERPs to light flashes were recorded during and immediately after auditorily presented ambiguous and unambiguous target sentences. Each target sentence was preceded by either a relevant or a neutral context sentence. Principal component analyses of the ERPs indicated that although certain components varied as a function of ambiguity, none of the components varied as a function of preceding context. These findings provided some support for a postdecision model of ambiguity processing which suggests that both meanings of an ambiguity are always processed, even when prior disambiguating context is available. 相似文献

Several recent studies have indicated that the degree and direction of bilateral skin conductance (BSC) asymmetry and the direction of conjugate lateral eye movements (CLEMs) both index hemispheric functioning. Evidence also suggests that BSC asymmetry decreases and CLEMs become more unidirectional as level of arousal increases. Thirty-two normal adults received an habituation series of five-second tones followed by 40 questions. All stimuli were tape recorded. The questions (Schwartz, Davidson, and Maer, 1975) were grouped in four series: 10 verbal-emotional, 10 verbalnonemotional, 10 spatial-emotional, and 10 spatial-nonemotional. The order in which the four series were presented was counterbalanced across subjects. Prior to each question, subjects fixated the face of a mannequin. Sixteen subjects (high arousal) had five seconds to contemplate their answer; the remaining 16 (low arousal) had 10 seconds. Instructions for the high arousal group specified that intelligence and problem-solving ability was being tested, and that speed and accuracy were very important. Those for the low arousal group indicated casually that subjects were to ponder a series of questions. BSC levels, SC response amplitudes, and CLEMs were measured during a five-second interval following each tone or question. BSC levels were greater under the High Arousal condition. While approximately two-thirds of the subjects showed BSC asymmetry (roughly evenly divided between those with larger left and right hand responses), neither the degree nor direction of the asymmetries changed as a function of question type. While CLEM direction was more sensitive to question type under low arousal, (i.e., verbal questions resulted in predominantly right-going CLEMs and spatial questions resulted in predominantly left-going CLEMs) they tended to be stereotyped (i.e., unidirectional) under high arousal. Finally, no relationship was observed between CLEM direction and BSC asymmetry under either high or low arousal condition. 相似文献
