Elliott and Shewchuk (1996) assert that counseling psychology should have considerable potential to influence national healthcare and public policy. A mechanism for realizing this potential entails being responsive to national, state and private funding initiatives for reaearch and other programmatic activities. To examine the extent to which counseling psychology resarch reflects an involvement in these initiatives, we studied the rate of sponsored research in three journals traditionally associated with mainstream counseling psychology research. We compared this rate with that observed in oher applied and theoretically oriented psychological journals. In comparison with the research published in the other outlets, results indicated that the mainstream counseling psychology literature has a disproportionately low level of sponsorship from national and federal sources. The scant representation of federally-funded research in the counseling psychology literature may effectively preclude full participation in addressing and setting national funding priorities and other health care and public policies germane to the field. Several issues are raised and discussed in light of these findings. 相似文献

It is not clear from the literature why, as children develop, there are important increases in memory span, the number of just-presented items that the participant can repeat in the correct serial order. To understand this, some recent results on capacity limits and processing rates were re-analyzed. We first describe results using a conventional measure of performance in immediate memory tasks that is affected by the list length (proportion correct). Next we describe results using a less conventional measure (number correct) that is unaffected by list length under circumstances in which attention to the list during its presentation is curtailed. This measure can estimate an individual's limited-capacity storage ability. Last, we examine measures of spoken response timing that do and do not change with list length. We show that unconventional measures that do not change with list length, but do change with development, are especially useful in assessing basic changes in information processing parameters, including increases in memory capacity and processing speed. 相似文献

Jeff McMahan's impressive recent defence of the embodied mind theory of personal identity in his highly acclaimed work The Ethics of Killing has undoubtedly reawakened belief that physical continuity is a necessary component of the relation that matters in our self-interested concern for the future. My aim in this paper is to resist this belief in a somewhat roundabout way. I want to address this belief in a somewhat roundabout way by revisiting a classic defence of the belief that enormous changes in the contents of a person's psychology does not preclude justified fear of future pain. I have in mind Bernard Williams' The Self and the Future (1970) in which he argues, against the psychological view, that physical continuity is necessary for survival. I examine Williams' second thought experiment which ostensibly supports that intuition and afterwards defend two related claims. First, I argue that a close examination of the second thought experiment reveals that one's prior commitments to a particular criterion of personal identity can influence one's response to that thought experiment. Second, I argue that Williams' second thought experiment is set out in questionbegging terms. I do not claim, however, that the intuition under consideration lacks justification; I only claim that Williams' second thought experiment does not provide the needed support. 相似文献

Three experiments examined the role of the degree of temporal contiguity between an action and an outcome in human causality judgement. In all the experiments subjects were required to perform an action—pressing a key on a computer keyboard—and to judge the extent to which the action caused an outcome on the computer screen to occur. The action and outcome occurred on a free-operant schedule. In the first experiment a 2-sec delay between the action and outcome reduced causality judgements relative to a situation in which there was no delay. In the second experiment judgements in conditions with delays of 0, 4, 8, and 16 sec were compared with judgements in conditions in which the same pattern of outcomes occurred non-contingently with respect to the subjects' responding. In both of these experiments the events were controlled by random ratio schedules, following the procedure of Wasserman, Chatlosh, and Neunaber (1983), in which each condition was divided into 1-sec intervals. In the third experiment judgements in conditions with delays of 0, 2, 4, or 8 sec were compared in a continuous procedure rather than one divided into 1-sec intervals. In all experiments the increasing delays led to progressively lower judgements of causality. The results are related to three accounts of the mechanism underlying human causality judgement and are also compared with results from analogous animal conditioning studies. 相似文献

In the first study, rats were trained to pull a chain on a schedule (RPI) that regulates the probability of reinforcement to maintain a constant average reinforcement rate without differentially reinforcing long inter-response times (IRTs). Although the response rate was sensitive to the overall rate of reinforcement, performance was unaffected by variations between 1 and 50 in the IRT memory size used in programming the schedule. In the second study, two groups of animals performed on either a random-interval (RI) schedule or a RPI schedule, with reinforcement rates determined by those generated by a third group performing on a random ratio (RR) 20 schedule. The RI group responded at a lower rate than the RPI group, which, in turn, responded at a lower rate than the RR group, even though the three groups experienced comparable rates of reinforcement. The fact that the RPI group responded at a lower rate than the RR group suggests that the standard response rate difference observed between ratio and interval schedules, which have been matched for reinforcement rate, cannot be attributed solely to the fact that conventional interval schedules differentially reinforce long IRTs. 相似文献

An experiment was conducted to examine the contribution of the hemispheres to the organization of aiming movements. The spatial positions of targets were obtained by extrapolating from brief visual displays of geometric patterns. The patterns comprised linear, quadratic, cubic, and quartic mathematical functions and varied in spatial complexity. Vision of the hand was also manipulated. While the hands did not differ in spatial accuracy, movements made by the right hand were of shorter duration and had higher peak velocities. The stimulus pattern strongly influenced kinematics, in particular the number of discrete modifications of the movement trajectory. Vision of the hand resulted in superior accuracy, although subjects were unable to compare the relative positions of the limb and the target. Vision of the hand did not lead to an increase in discrete adjustments, suggesting that visual information was used in a continuous fashion. Movements into ipsilateral space differed from those into contralateral space with respect to a number of parameters. 相似文献
