Studies were designed to compare the effects of encoding strategies on two types of interference, sensory and semantic. Paired-associate lists were learned under instructional sets encouraging interactive imagery or repetitious rehearsal. Sensory interference was created by mispairing rhymes and semantic interference was produced by mispairing associatively related words. In control lists word pairs were unrelated. The results indicated that encoding strategy did not influence amounts of sensory and semantic interference. Mispairing rhymes produced the same amount of confusion as mispairing associates whether pairs were encoded through interaction imagery or through repetitious rehearsal. These effects were found with both short and long encoding intervals. The findings are inconsistent with the idea that encoding operations or strategies applied to word pairs completely determine the type of code activated for those pairs. Both sensory and semantic codes appear to be activated under each kind of encoding strategy. 相似文献

Scaling analysis based on variable criterion theory has been applied to the c-reaction form of disjunctive RT. In addition to previously identified sensory growth functions, two associative processes have been identified and functions of time describing their growth have been obtained. Associative strength to the positive stimulus begins at about 200 msec, or after, and grows with initial positive and later negative acceleration. Associative inhibition to the negative stimulus begins earlier, shortly after the sensory detection functions, and grows rapidly with negative acceleration. Subjects may adopt strategies which emphasize the use of either of these associative processes. With the pure inhibitory strategy, they respond to the positive stimulus entirely on the basis of sensory detection, but associatively inhibit response to the negative stimulus. With either strategy, the speed-accuracy tradeoff was determined by the level of criterion adjustment. 相似文献

Three studies were conducted to determine the effects of observing the behaviors of others upon an individual's actions in a simulated social trap situation. In Experiment 1, it was found that merely having the opportunity to make comparative appraisals of the actions of others led to greater competition for a finite common resource than when subjects were physically isolated from one another. In Experiment 2, false feedback was given to subjects to determine if the actions of others alone were responsible for the deleterious effects of having the opportunity for comparative appraisal; it was found that subjects quickly conformed to the behavior pattern of the interacting others, regardless of whether the false feedback indicated that the other subjects were consuming more or less than no-treatment control subjects. Experiment 3 was conducted to determine the motivation of subjects reacting to the actions of others; differential predictions based upon a competition/relative outcome explanation and upon an information search explanation were made. The data were consistent with the information search explanation. 相似文献

Recent models in quantum cosmology make use of the concept of imaginary time. These models all conjecture a join between regions of imaginary time and regions of real time. We examine the model of James Hartle and Stephen Hawking to argue that the various no-boundary attempts to interpret the transition from imaginary to real time in a logically consistent and physically significant way all fail. We believe this conclusion also applies to quantum tunneling models, such as that proposed by Alexander Vilenkin. We conclude, therefore, that the notion of emerging from imaginary time is incoherent. A consequence of this conclusion seems to be that the whole class of cosmological models appealing to imaginary time is thereby refuted.We would like to thank Quentin Smith for helpful comments on an carlier version of this eassy.

We develop hypothese based on the research literature regarding behavioral responses to aversive stimuli. Specifically, escape, avoidance, and countercontrol responses are presented as teacher behaviors which may occur in the presence of disruptive and aggressive behaviors (aversive stimuli) which, in part, characterize many students with severe behavior disorders (SBD). The potential for teacher escape, avoidance, and countercontrol responses to the detrimental for both teachers and students is presented, as well as suggestions for addressing aversive behaviors of students in ways to reduce the potential detrimental impact. 相似文献

The purpose of the present study was to assess the effects of exposure to nonviolent rap music on African American adolescents' perceptions of teen dating violence. African American male and female subjects were exposed to nonviolent rap videos (which contained images of women in sexually subordinate roles) or they saw no videos. They read a vignette that involved teen dating violence perpetrated by a male. The results indicated that there was a significant interaction between gender and video exposure. More specifically, acceptance of the use of violence did not vary as a function of exposure for male subjects. Conversely, female subjects who were exposed to the videos showed greater acceptance of the violence than females who were not exposed. Possible basis and implications for these findings are discussed.To whom reprint requests should be addressed at Department of Psychology, The University of North Carolina at Wilmington, 601 South College Road, Wilmington, NC 28403-3297. 相似文献

Two experiments examined the effect of various relationships between a response (pressing the space bar of a computer) and an outcome (a triangle flashing on a screen) on judgments of the causal effectiveness of the response. In Experiment 1, when responses were required to be temporarily isolated from each other prior to an outcome, ratings of the causal effectiveness of the responses were higher than in a condition in which the probability of an outcome following a response was the same but in which no temporal isolation was required. In Experiment 2, when a number of responses were required to be emitted temporally close to the outcome, ratings of the causal effectiveness of the responses were lower than in a condition in which the probability of an outcome following a response was the same but in which no temporal proximity was required. These results suggest that, in addition to the overall probability that an outcome will follow a response, the local context of responding at the time an outcome is presented is critical in influencing ratings of causal effectiveness. 相似文献
