Arthur I. Miller 《国际科学哲学研究》1991,5(1):35-48
Taking the integrated viewpoints of causal theory of reference, cognitive science and the notion of correspondence principles from physics, this paper addresses the problems of creativity, the nature of visual imagery and the manner in which science progresses. 相似文献

Discrete versus continuous stage models of human information processing: in search of partial output 总被引:3,自引:0,他引:3
This article introduces a new technique designed to study the flow of information through processing stages in choice reaction time tasks. The technique was designed to determine whether response preparation can begin before stimulus identification is complete ("continuous" models), or if a stimulus must be fully identified prior to any response activation ("discrete" models). To control the information available at various times during stimulus identification, some relevant stimulus characteristics were made easy to discriminate and some were made hard to discriminate. The experimental strategy was to look for effects of partial output based on information conveyed by characteristics that were easy to discriminate. The technique capitalized on the fact, demonstrated in Experiment 1, that preparation of two response fingers on the same hand is more effective than preparation of two response fingers on different hands. The usefulness of partial output was varied by manipulating the assignments of stimuli to responses. For some mappings partial information could contribute to effective response preparation because the responses consistent with partial information were assigned to fingers on the same hand. For other mappings partial information could not contribute to effective response preparation because the responses consistent with partial information were assigned to fingers of different hands. Performance differences between these mappings were considered evidence that partial information about a stimulus was transmitted to response activation processes before the stimulus was uniquely identified, and thus were considered evidence against discrete transmission of information about the stimulus as a whole. A variety of stimulus sets were studied; the results suggest that information is transmitted discretely with respect to stimulus codes, although distinct codes activated by a single stimulus may be transmitted at different times. 相似文献

Five classes of relations between an object and its setting can characterize the organization of objects into real-world scenes. The relations are (1) Interposition (objects interrupt their background), (2) Support (objects tend to rest on surfaces), (3) Probability (objects tend to be found in some scenes but not others), (4) Position (given an object is probable in a scene, it often is found in some positions and not others), and (5) familiar Size (objects have a limited set of size relations with other objects). In two experiments subjects viewed brief (150 msec) presentations of slides of scenes in which an object in a cued location in the scene was either in a normal relation to its background or violated from one to three of the relations. Such objects appear to (1) have the background pass through them, (2) float in air, (3) be unlikely in that particular scene, (4) be in an inappropriate position, and (5) be too large or too small relative to the other objects in the scene. In Experiment I, subjects attempted to determine whether the cued object corresponded to a target object which had been specified in advance by name. With the exception of the Interposition violation, violation costs were incurred in that the detection of objects undergoing violations was less accurate and slower than when those same objects were in normal relations to their setting. However, the detection of objects in normal relations to their setting (innocent bystanders) was unaffected by the presence of another object undergoing a violation in that same setting. This indicates that the violation costs were incurred not because of an unsuccessful elicitation of a frame or schema for the scene but because properly formed frames interfered with (or did not facilitate) the perceptibility of objects undergoing violations. As the number of violations increased, target detectability generally decreased. Thus, the relations were accessed from the results of a single fixation and were available sufficiently early during the time course of scene perception to affect the perception of the objects in the scene. Contrary to expectations from a bottom-up account of scene perception, violations of the pervasive physical relations of Support and Interposition were not more disruptive on object detection than the semantic violations of Probability, Position and Size. These are termed semantic because they require access to the referential meaning of the object. In Experiment II, subjects attempted to detect the presence of the violations themselves. Violations of the semantic relations were detected more accurately than violations of Interposition and at least as accurately as violations of Support. As the number of violations increased, the detectability of the incongruities between an object and its setting increased. These results provide converging evidence that semantic relations can be accessed from the results of a single fixation. In both experiments information about Position was accessed at least as quickly as information on Probability. Thus in Experiment I, the interference that resulted from placing a fire hydrant in a kitchen was not greater than the interference from placing it on top of a mail ? in a street scene. Similarly, violations of Probability in Experiment II were not more detectable than violations of Position. Thus, the semantic relations which were accessed included information about the detailed interactions among the objects—information which is more specific than what can be inferred from the general setting. Access to the semantic relations among the entities in a scene is not deferred until the completion of spatial and depth processing and object identification. Instead, an object's semantic relations are accessed simultaneously with its physical relations as well as with its own identification. 相似文献

John W. Miller Th. D. 《Journal of religion and health》1982,21(1):62-67
Many questions are currently being raised, by women especially, regarding the religious, social, and psychological effects of the emphasis on God as father in Western religion. Viewed in the light of key insights from developmental psychoanalysis, patriarchal monotheism does indeed seem to confront us with a dilemma. However, a resolution of this dilemma does not appear to lie in a move toward androgyny or matriarchy. Evaluated from the point of view of its overall capacity to mediate a meaningful, unified, personal religious reality to both sexes, monotheistic father religion is still the preferable ultimate symbolic configuration. 相似文献

Controllability and human stress: method, evidence and theory. 总被引:4,自引:0,他引:4
S M Miller 《Behaviour research and therapy》1979,17(4):287-304
Concepts are defined and evidence reviewed on whether control reduces stress in man. Individuals seem to prefer instrumental control over an aversive event, seem to prefer to administer it to themselves, and are less aroused when waiting for a controllable event. When groups without control have equal predictability, having control is still less arousing; as potential (but unexercised) control seems to be. The evidence also suggests that controllable events may hurt less. Methodological weaknesses and empirical gaps in these data are pointed out. These data are grossly inconsistent with Relevant Feedback theory and rather inconsistent with Information-seeking theory and Safety Signal theory. A Minimax hypothesis is proposed: When individuals control aversive events, they believe relief to be caused by a stable source—their own response. This belief entails that maximum future danger will be minimized. When they have no control, they believe relief to be less stable, which entails no guarantee that maximum future danger will be minimized. The data are largely consistent with the Minimax hypothesis and wholly consistent when Minimax is supplemented by the premise that aversive events hurt less when encountered against a background of relaxation. 相似文献
