We evaluated whether teaching tacts of images with or without backgrounds would affect acquisition during teaching and generality across untaught targets with four children diagnosed with autism spectrum disorder. Including backgrounds could slow acquisition but bolster generality across other media containing backgrounds, whereas removing backgrounds may improve acquisition but result in poorer generality. Overall, acquisition rates were similar across conditions for three children, although one child displayed consistently slower acquisition during the background condition. We rarely observed generality to untaught targets when programming extinction, but embedding differential reinforcement or teaching additional images with backgrounds led to equally successful outcomes irrespective of initial teaching conditions. Teaching with or without backgrounds may result in marginal differences in acquisition of teaching and untaught targets, especially when arranging supplemental procedures during tests for generality. We discuss the importance of intrasubject replication, considerations when testing for generality, and implications for practice. 相似文献

Many philosophers take experience to be an essential aspect of perceptual justification. I argue against a specific variety of such an experientialist view, namely, the Looks View of perceptual justification, according to which our visual beliefs are mediately justified by beliefs about the way things look. I describe three types of cases that put pressure on the idea that perceptual justification is always related to looks‐related reasons: unsophisticated cognizers, multimodal identification, and amodal completion. I then provide a tentative diagnosis of what goes wrong in the Looks View: it ascribes a specific epistemic role to beliefs about looks that is actually fulfilled by subpersonal perceptual processes. 相似文献

本研究以281名老年人为研究对象,探讨了城市变迁中的老年人居住地情感认同、领悟社会支持和控制感的关系。研究使用居住地情感认同问卷、领悟社会支持问卷和控制感问卷为研究工具,采用每次间隔6个月,共3次的纵向追踪设计。结果发现:老年人的居住地情感认同可以正向预测领悟社会支持,老年人的领悟社会支持可以正向预测控制感,老年人的领悟社会支持在居住地情感认同和控制感之间起纵向中介作用。本研究结果揭示了城市老年居民的居住地情感认同对控制感的影响机制,也对提升城市老年居民的控制感具有一定的实践意义。 相似文献

Brief multiple-stimulus-without-replacement (MSWO) preference assessments were conducted with 3 adolescent boys with emotional-behavioral disorders in the context of their public school educational program. The reinforcing effects of stimuli identified as high, medium, and low preference were then evaluated using an alternating treatments design in which, following an initial baseline, stimuli were delivered contingent on on-task behavior. High-preference stimuli produced the highest percentages of on-task behavior for all 3 participants. 相似文献

This paper examined conceptual versus perceptual priming in identification of incomplete pictures by using a short-term priming
paradigm, in which information that may be useful in identifying a fragmented target is presented just prior to the target’s
presentation. The target was a picture that slowly and continuously became complete and the participants were required to
press a key as soon as they knew what it was. Each target was preceded by a visual prime. The nature of this prime varied
from very conceptual (e.g., the name of the picture’s category) to very perceptual (e.g., a similar-shaped pictorial prime
from a different category). Primes also included those that combined perceptual and conceptual information (e.g., names or
images of the target picture). Across three experiments, conceptual primes were effective while the purely perceptual primes
were not. Accordingly, we conclude that pictures in this type of task are identified primarily by conceptual processing, with
perceptual processing contributing relatively little. 相似文献

Ethics has become an increasingly important issue within engineering as the profession has become progressively more complex.
The need to integrate ethics into an engineering curriculum is well documented, as education does not often sufficiently prepare
engineers for the ethical conflicts they experience. Recent research indicates that there is great diversity in the way institutions
approach the problem of teaching ethics to undergraduate engineering students; some schools require students to take general
ethics courses from philosophical or religious perspectives, while others integrate ethics in existing engineering courses.
The purpose of this paper is to propose a method to implement the integration of ethics in engineering education that is pedagogically
based on Kohlberg’s stage theory of moral development. 相似文献

In this essay, the author recommends a reformulation of the psychoanalytic concept of pojection. The author proposes that projective processes are not merely defensive maneuvers that interfere with perception, but rather an essential means by which human perception is rendered possible. It is the manner in which human beings test and-evaluate reality in terms of their experiential structure, and their needs for survival and nourishment. Projection is the early phase of introjection. 相似文献

Lip reading is the ability to partially understand speech by looking at the speaker's lips. It improves the intelligibility of speech in noise when audio-visual perception is compared with audio-only perception. A recent set of experiments showed that seeing the speaker's lips also enhances sensitivity to acoustic information, decreasing the auditory detection threshold of speech embedded in noise [J. Acoust. Soc. Am. 109 (2001) 2272; J. Acoust. Soc. Am. 108 (2000) 1197]. However, detection is different from comprehension, and it remains to be seen whether improved sensitivity also results in an intelligibility gain in audio-visual speech perception. In this work, we use an original paradigm to show that seeing the speaker's lips enables the listener to hear better and hence to understand better. The audio-visual stimuli used here could not be differentiated by lip reading per se since they contained exactly the same lip gesture matched with different compatible speech sounds. Nevertheless, the noise-masked stimuli were more intelligible in the audio-visual condition than in the audio-only condition due to the contribution of visual information to the extraction of acoustic cues. Replacing the lip gesture by a non-speech visual input with exactly the same time course, providing the same temporal cues for extraction, removed the intelligibility benefit. This early contribution to audio-visual speech identification is discussed in relationships with recent neurophysiological data on audio-visual perception. 相似文献

A survey on ethical issues in engineering was administered over a five-year period to Stanford engineering students and practicing
engineers. Analysis of its results strongly suggests that important disconnects exist between the education of engineering
students regarding ethical issues in engineering on the one hand, and the realities of contemporary engineering practice on
the other. Two noteworthy consequences of these gaps are that the views of engineering students differ substantially over
what makes an issue an ethical issue, while practicing engineers exhibit significant disagreement over what is the most important
non-technical aspect of being a responsible engineering professional in contemporary society. These divergences impede the
recognition of ethical issues and of specific moral responsibilities of engineers in concrete professional practice. It is
argued that the use of suitably refined and probing surveys of engineering students and practicing engineers about ethical
issues in engineering is an important although neglected empirical approach to the study of engineering ethics. Such an approach
can enhance the prevailing case study method and combat over-tidy theoretical-analytical approaches to the subject.
When a train arrives at a station in the London Underground, a public announcement cautions passengers to “mind the gap”,
i.e. heed the space between the station platform and the carriage while entering or exiting.

This article focuses mainly on (1) the policy of Delft University of Technology since 1992 as regards the university-wide
introduction of a compulsory course on ethics and engineering, and (2) the ideal structure of such a course, including the
educational goals of the course.
