Dienes and Berry (1997) argue that there really are two kinds of knowledge, implicit and explicit, that can be characterized through a subjective threshold. We argue that the subjective threshold does not separate two forms of knowledge, but instead two uses of knowledge, for two different purposes. With Neal and Hesketh (1997), we suggest that an understanding of learning will be better served by investigating the processing that occurs under various circumstances than by attempting to isolate learning that occurs with awareness from that which occurs without it. 相似文献

Studies of saccadic suppression and induced motion have suggested separate representations of visual space for perception and visually guided behavior. Because these methods required stimulus motion, subjects might have confounded motion and position. We separated cognitive and sensorimotor maps without motion of target, background, or eye, with an “induced Roelofs effect”: a target inside an off-center frame appears biased opposite the direction of the frame. A frame displayed to the left of a subject’s center line, for example, will make a target inside the frame appear farther to the right than its actual position. The effect always influences perception, but in half of our subjects it did not influence pointing. Cognitive and sensorimotor maps interacted when the motor response was delayed; all subjects now showed a Roelofs effect for pointing, suggesting that the motor system was being fed from the biased cognitive map. A second experiment showed similar results when subjects made an open-ended cognitive response instead of a five-alternative forced choice. Experiment 3 showed that the results were not due to shifts in subjects’ perception of the felt straight-ahead position. In Experiment 4, subjects pointed to the target and judged its location on the same trial. Both measures showed a Roelofs effect, indicating that each trial was treated as a single event and that the cognitive representation was accessed to localize this event in both response modes. 相似文献

Two experiments were conducted with the primary purpose of investigating the ability of right brain-damaged (RBD) individuals to use contextual information—at the level of the single sentence, in terms of the integration of information between clauses, and at the level of a minimal discourse (i.e., two sentences)—in the resolution of ambiguous pronouns. The investigation was extended to a group of left brain-damaged (LBD) and non-brain-damaged (NBD) individuals. Contrary to the prevailing view that RBD patients have difficulty in the use of contextual information to process language, both experiments were consistent in demonstrating that the RBD group was influenced by contextual information in a manner similar to that demonstrated by both the LBD and NBD groups. 相似文献

Recent medical studies documenting the influence of prayer in our physical lives challenge mainstream Christians to rethink their ideas and practice of prayer. A new model of prayer questions dysfunctional images of prayer based on 1) the doctrine of divine omnipotence, 2) the rewards-punishments notion of health and illness, and 3) linear notions of the power of prayer. Relational, holistic, and multidimensional images of God, human existence, and the effects of prayer provide the basis for a constructive theology of prayer. Ironically, the fact that prayer is not omnipotent makes it possible to practice prayer in a technological context. 相似文献

Research on attitudes toward the stigmatized indicates that negative feelings and stereotypes toward the stigmatized are often mixed with positive feelings of sympathy and concern. Three studies investigate the hypothesis that positive outcomes for the stigmatized that are motivated by sympathy may have unintended negative consequences for self-esteem, affect, and motivation. Subjects were asked to imagine themselves in the position of a stigmatized person who received a job either because he or she was qualified, or out of sympathy for a stigmatizing condition. Results indicated that subjects reported lower state self-esteem, more negative affect, and lowered work motivation when the job was offered out of sympathy rather than on the basis of qualifications. Study 2 showed that the negative effects of sympathy occur whether the basis for the sympathy is prejudice and discrimination or mobility problems faced by the stigmatized individual. The third experiment showed that sympathy has negative effects when the sympathy is based either on individual or group-based problems imposed by the stigmatizing condition. The findings are discussed in terms of the attributional ambiguity surrounding positive outcomes faced by the stigmatized and applied to the effects of affirmative-action programs. 相似文献
