Does anticipated future racial discrimination undermine African-American adolescents' academic motivation and performance? Do face-to-face experiences with racial discrimination at school undermine African-American adolescents' academic functioning? Does African-American ethnic identity buffer these relations? This paper addresses these questions using two waves of data from a longitudinal study of an economically diverse sample of African-American adolescents living near Washington D.C. The data were collected at the beginning of the 7th grade and after the completion of the 8th grade. As expected, the experiences of day-to-day racial discrimination at school from one's teachers and peers predicted declines in grades, academic ability self-concepts, and academic task values. A strong, positive connection to one's ethnic group (our measure of ethnic identity) reduced the magnitude of the association of racial discrimination experiences with declines in both academic self-concepts and school achievement. Most youth responded to anticipated future discrimination with increased academic motivation.  相似文献

Mary Shelley’s novel “Frankenstein; or, the Modern Prometheus” is presented here as her encoded image of unconscious emotions too painful for her waking personality to deal with. Her innovative image of man-made life is taken as emerging from the confrontation of her hopes for secure love with painful events in her life with Percy Shelley. This paper proposes that her novel served as a waking expression of unconscious feelings of hurt in reaction to Percy. The monster’s role is here decoded as her way to consciously process the idea that parts of her relation to Percy were so hurtful as to deform it into a miscreant. It is further proposed that the losses and frustrations of her earliest years inclined her to accept Percy’s violations in the hope of the secure love she longed for. The answer offered to this paper’s title accounts for why “Frankenstein” is taken to refer to the unnamed monster and not its creator.Anthony F. Badalamenti is a research scientist in psychiatry.

Recent evidence suggests that drug-induced conditioned taste avoidance may be mediated by conditioned fear (e.g., Parker, 2003). The experiments reported here evaluated the effect of exposure to a drug-paired flavor on open arm exploration in an elevated plus maze (EPM), a measure of fear. When rats were tested on a familiar (trial 2) EPM, but not on a novel (trial 1) EPM, prior exposure to a lithium-paired saccharin solution enhanced open arm activity relative to saline-paired saccharin. On the other hand, when rats were exposed to lithium-paired saccharin during plus maze exposure, they displayed suppressed open arm activity relative to unpaired controls when tested in a familiar maze. The pattern of results was specific to the conditional affective properties of the taste, because exposure to unconditional sickness produced by administration of lithium, and unconditionally unpalatable quinine solution did not produce this pattern. These results were interpreted in terms of the opponent process model of motivation; that is, exposure to a lithium-paired flavor elicits conditioned fear which is immediately followed by conditioned relief when the exposure is terminated. On the other hand, exposure to an amphetamine-paired flavor either before or during EPM testing enhanced open arm exploration. Since the strength of taste avoidance did not differ among amphetamine and lithium conditioned rats, these results provide further evidence that the nature of a saccharin-lithium association differs from that of a saccharin-amphetamine association.  相似文献

Habits—A Repeat Performance   总被引:1,自引:0,他引:1  
ABSTRACT— Habits are response dispositions that are activated automatically by the context cues that co-occurred with responses during past performance. Experience-sampling diary studies indicate that much of everyday action is characterized by habitual repetition. We consider various mechanisms that could underlie the habitual control of action, and we conclude that direct cuing and motivated contexts best account for the characteristic features of habit responding—in particular, for the rigid repetition of action that can be initiated without intention and that runs to completion with minimal conscious control. We explain the utility of contemporary habit research for issues central to psychology, especially for behavior prediction, behavior change, and self-regulation.  相似文献

Treatment motivation is required for virtually all psychosocial treatments because clients must participate actively in the treatment process. In child and family treatments, it is the parent who must be motivated to manage treatment participation; however, no measures are currently available for evaluating parent motivation for treatment. The authors developed and evaluated a brief rating scale, the Parent Motivation Inventory (PMI), to measure parent motivation to participate in treatment. Results supported a uni-dimensional measure with strong internal consistency and test-retest reliability. Increases in parent motivation predicted the perception of fewer barriers to treatment participation, which was significantly associated with greater treatment attendance. The PMI provides a reliable and valid method of assessing parents’ motivation to participate in treatment and has implications for the prediction and potential modification of barriers to treatment and treatment participation.  相似文献

The phenomenological goal of grounding the content of conceptual thought in the background understanding of everyday, skillful coping was approached using evolutionary autonomous agent (EAA) methodology. The behavior of an EAA evolved to perform a specified motor task was identified with skillful coping. Changes in the dynamics of the EAA controller occurred when the EAA encountered an unexpected obstacle with loss of longer time scale components in its hierarchical temporal organization. These temporal changes are consistent with the phenomenological changes which we experience with breakdown during equipment use with our adoption of a more immediate, determinate stance. Since this latter experience is the basis of conceptual thought, the EAA paradigm goes some way in providing a naturalized explanation for the grounding of the content of conceptual thought in everyday, skillful coping in a manner that is physiologically plausible and phenomenologically accurate.  相似文献

In Experiment 1, a light and a tone were correlated independently with water reinforcement of bar pressing by rats. With different naive subjects in Experiment 2, one of these stimuli was correlated with food and the other with water reinforcement (counterbalanced). In both experiments the absence of tone and light signaled extinction. Tests of stimulus-reinforcer independence in Experiment 2 indicated that tone and light controlled behavior whose rate was specifically affected by deprivation state. In the stimulus-compounding tests of both experiments, response rates were higher to tone-plus-light than to tone or light presented alone (additive summation). This is the first report of additive summation produced through compounding stimuli paired with different reinforcers. The results are discussed in the context of the effects of incentive motivation on operant performance.  相似文献

This essay is an introduction to systematic nonsectarian psychology of religion—its nature and scope, and its history. Among major issues, the study of motivation for being religious and stages of religious development are discussed, as well as counseling and psychotherapy. I summarize current trends.  相似文献

The nature of sexual reinforcement.   总被引:3,自引:1,他引:2       下载免费PDF全文
Sexual reinforcers are not part of a regulatory system involved in the maintenance of critical metabolic processes, they differ for males and females, they differ as a function of species and mating system, and they show ontogenetic and seasonal changes related to endocrine conditions. Exposure to a member of the opposite sex without copulation can be sufficient for sexual reinforcement. However, copulatory access is a stronger reinforcer, and copulatory opportunity can serve to enhance the reinforcing efficacy of stimulus features of a sexual partner. Conversely, under certain conditions, noncopulatory exposure serves to decrease reinforcer efficacy. Many common learning phenomena such as acquisition, extinction, discrimination learning, second-order conditioning, and latent inhibition have been demonstrated in sexual conditioning. These observations extend the generality of findings obtained with more conventional reinforcers, but the mechanisms of these effects and their gender and species specificity remain to be explored.  相似文献
