A microcomputer-based system is described for the automatic acquisition, storage, and analysis of rodent food intakes. The feed-o-meter provides reliable, valid measurements of consumption, with minute-by-minute accuracy of ?.03 g. 相似文献

Patterns of cigarette smoking, treated as series of discrete events in time, were investigated with a variety of quantitative techniques designed to characterize individual subject smoking series and to illuminate the relationship between cigarette smoking and environmental events. Data were collected from a total of 35 subjects who were either participants in residential laboratory studies or in a smoking cessation program. Cigarette smoking events were found to be fairly irregularly distributed with respect to time within individual subject series. However, strong dependencies were found between the occurrence in time of individual acts of cigarette smoking and coffee drinking. In addition, the distribution and frequency of smoking events throughout one-hour activity sequences were found to be dependent upon the nature of the activity, and the temporal scheduling of activities was found to affect several quantitative indices of smoking patterns. 相似文献

Can alcohol reduce tension? 总被引:1,自引:0,他引:1
The Tension Reduction Hypothesis of alcohol use is examined in the light of recent criticism. Contrary to the conclusions of Cappell and Herman (1972) it is argued that the hypothesis is supported by evidence from animal research in most cases where an appropriate paradigm has been employed. 相似文献

Obsessional-compulsive complaints 总被引:14,自引:0,他引:14
A simple questionnaire was developed as an instrument for assessing the existence and extent of different obsessional-compulsive complaints. Two major types of complaint, checking and washing compulsions, and two minor types, slowness and doubting, were established. The final form of the questionnaire, and major properties, are presented. 相似文献

Five pigeons were run on a one-key discrete trials observing procedure. Trial onset was signaled by a white or yellow key light. Pecks in white or yellow intermittently produced S+ and S−, green and red key lights that signaled whether the trial would end with response-independent grain reinforcement or nonreinforcement. In the Redundant conditions, white and yellow were correlated with trial outcome, making S+ and S− redundant. In the Informative condition, white and yellow were uncorrelated with trial outcome, so that S+ and S− provided new information. During the Informative condition, all birds responded in the formerly positive, now uncorrelated color at higher rates than they did during the preceding or succeeding Redundant conditions, in which that same color was positively correlated with primary reinforcement. This result confirmed the prediction that an animal will observe at higher rates in the absence of reinforcement-correlated cues than in their presence. 相似文献

A theory of intelligence is couched in stimulus-response terms, bridging the gap between S-R and cognitive psychology. The chief theoretical concepts are span ability (a capacity notion), response string (sequentially cued responses), and complexity of stimulus control (task complexity). Span is equated with the ability to respond appropriately when several cues are conjunctively relevant for correct performance (complex stimulus control). So defined, span is consistently and broadly related to many aspects of intelligent behavior. 相似文献

The role of knowledge of the reversibility of reversible figures was tested in four experiments. Two ambiguous figures, the vase-face figure and a depth-reversing pyramid-hallway figure were shown to high school students. In the Uninformed condition, subjects were not told that the figures were reversible. A sampling procedure was used in which subjects reported what they perceived at 5-sec intervals. Viewing durations of up to 3 min were used, and approximately half of all subjects did not reverse at all during the uninformed condition, whereas virtually all subjects reversed quickly and frequently once they knew that the figures were reversible. These results are not consistent with neural fatigue models of perceptual reversal. 相似文献
