Three students with moderate handicaps were taught to initiate and expand on conversational topics. The teaching procedure used stimuli generated from actual conversations with nonhandicapped peers. Generalization was assessed by audiotaping conversations between the handicapped students and their peers in natural school contexts without adult supervision. Results indicated that training generalized to natural contexts. These results were socially validated by undergraduate special education students, who rated tapes of two of the students' conversations during training phases as more socially competent than during baseline. Results are discussed in terms of the evaluation of complex social behavior as multioperant behaviors. 相似文献

A direct method in handling incomplete data in general covariance structural models is investigated. Asymptotic statistical properties of the generalized least squares method are developed. It is shown that this approach has very close relationships with the maximum likelihood approach. Iterative procedures for obtaining the generalized least squares estimates, the maximum likelihood estimates, as well as their standard error estimates are derived. Computer programs for the confirmatory factor analysis model are implemented. A longitudinal type data set is used as an example to illustrate the results.This research was supported in part by Research Grant DAD1070 from the U.S. Public Health Service. The author is indebted to anonymous reviewers for some very valuable suggestions. Computer funding is provided by the Computer Services Centre, The Chinese University of Hong Kong. 相似文献

Running over uneven ground requires visually regulating step length to secure proper footing. To examine how this is achieved, we studied subjects running on a treadmill on a series of irregularly spaced targets. The movements of their lower limbs and coccyx relative to the targets were monitored opto-electronically by a Selspot system. The results indicated that step length was adjusted to strike the targets primarily by varying the vertical component of impulse applied to the ground during the stance phase. In contrast, horizontal impulse was not varied significantly, and changing the reach forward of the foot on landing contributed little to variation in step length. Changing the vertical impulse simply altered the step time proportionately. Thus the data are consistent with a time-based model in which vertical impulse is modulated by the optic variable delta tau (Lee, 1976) specifying the time gap that has to be bridged by the runner between two targets. 相似文献

Though the term “new technology” is widely used and discussed, there has been very little systematic study of attitudes to
technology and their relation to other beliefs and group memberships. This article describes an initial investigation into
the nature of attitudes towards new technology (n=534 undergraduates) and demonstrates that, as yet, these attitudes are only weakly structured and are not fully integrated
with other social beliefs. General evaluations of the benefits of technological advance appear to be almost unrelated to beliefs
about the inevitability of these advances or the desire to acquire training to deal with them. Contrary to popular expectations,
evaluations of video games are unrelated to other beliefs about technology while other social beliefs are, as yet, only weakly
integrated with these attitudes. This study also identifies gender differences in the assessment of potential benefits and
highlights other differences attributable to academic group memberships. These finding are discussed with reference to the
literature on sex-role stereotyping and group socialization processes. 相似文献

This study examined whether norms that concerning assisting frail older parents were different for daughters than for sons when the adult children are members of dual-earner couples. Data were gathered by telephone interviews from a probability sample of 315 adults residing in western Alabama. Of the 18 statements presented, statistically significant differences between the expectations for daughters and sons occurred in only three cases (help with housework, meal preparation, and yard work), suggesting substantial support for norms of equalitarianism. Further, there were few differences between the expectations held by females and by males for daughters and sons. Generally, the results suggested strong support for behaviors that facilitate the independent living of both adult children and their frail older parents.The authors acknowledge with thanks the assistance of the University of Alabama's Capstone Poll, which collected the data for this study. 相似文献

This experiment examined whether structural considerations, that is the functional closeness of limb control centres (Kinsbourne and Hicks 1978), have a role to play in common processing models of psychological refractoriness. A typical double stimulation paradigm was used (Kantowitz 1974). On experimental trials, subjects responded with the right hand (RT1) to an auditory signal (0.80 probability). After a varied interstimulus interval (ISI) of 100, 200, 300 or 700 msec, one of three lights corresponding to one of the other limbs provided the signal for the second response (RT2). Control trials for RT1 and RT2 involved both stimuli, but subjects were required to make only one response. Results indicated that experimental RT1 was lengthened considerably over control values. While typical double stimulation effects were found at short ISIs, that is RT2 was lengthened, RT2 at long ISIs was actually faster than double stimulation control values. Although the RT results were not in a pattern that would be predicted by functional distance (Kinsbourne and Hicks 1978), within subject correlations of RT1 and RT2 by limb condition suggest that structural considerations may have a role to play. While within subject correlations were positive at all levels of ISI, they decreased as the interval between the two signals increased. The implications of these results for common processing models are discussed. 相似文献

Abstract. This essay sets forth the decisive notions and postulates of process philosophy in Process Philosophy and Social Thought , edited by John B. Cobb, Jr. and W. Widick Schroeder. After commenting on the circumstances in which process philosophy came to be a major option among philosophical theologians, I provide some amplification of those notions and postulates. Then, selecting material from the eighteen articles in the volume, I offer several critical assessments of the process viewpoint and its relation to science and to the contemporary call for liberation. 相似文献
