College students periodically experience many challenges in pursuit of their educational goals. Such experiences can have
deleterious effects on subsequent motivation and performance when they are perceived as negative. Research shows that some
students who experience negative events are buffered against motivational deficits, whereas others are motivationally at-risk.
Several individual difference variables have been proposed to account for such diverse reactions. A longitudinal field study
that involved three phases was conducted to extend this research. Phase I examined the motivational buffering effects of academic
attributional style on students' performance, motivation, and emotions. Results indicated that attributional style related
to students' performance, motivation, and emotions. Specifically, students who routinely made unstable and controllable attributions
for negative academic events exhibited the greatest performance and motivation compared to students who typically made stable
and uncontrollable attributions. Phases II and III were designed to examine the remedial benefits of attributional retraining
for different attributional styles. Findings indicated that attributional retraining influenced motivation, emotions, and
course grade. These results were qualified by the interaction between attributional style, attributional retraining, and time.
Findings are discussed within Weiner's (1985, 1986) attribution theory.
This research was based, in part, on the first author's dissertation submitted to the Department of Psychology and the Faculty
of Graduate Studies of The University of Manitoba in partial fulfillment for the Degree of Doctor of Philosophy. This research
was supported by a Social Sciences and Humanities Research Council of Canada (SSHRCC) doctoral fellowship, a University of
Manitoba doctoral fellowship, and a SSHRCC postdoctoral fellowship to the first author. In addition, the research was also
supported by a SSHRCC research grant (#410911296) to the second author. The authors gratefully acknowledge the helpful comments

Rev’d Ian StJohn Fisher Ph.D. 《Science and engineering ethics》1996,2(3):335-344
Religion, defined as ‘the idea of a state that transcends ourselves and our world and the working out of the consequences
of that idea’, may influence the ethical thinking of scientists and engineers in two ways. The first is at the level of the
individual and how personal beliefs affect the choice of research, design or development projects, relationships with other
researchers and the understandings of the consequences of research on other aspects of life. The second level is that of the
social and cultural setting in which scientists and engineers work; how society decides which research to sponsor, how to
apply the results of scientific discovery and which technology it chooses to develop and for what purposes. In neither of
these areas is religious belief a necessary condition for scientists and engineers to pursue one course of action rather than
another. The existence of religious belief within the individual and society is, though, part of the ethical framework in
which scientist and engineers work and therefore something to which attention should be paid. Religion provides a particular
perspective on what should be. Conversely science and technology provide information on the nature of the person and the universe
in which we live, which must be taken into account when theologians and religious moralists apply their ethical norms and
principles. 相似文献

Introduction and overview: Global information ethics 总被引:2,自引:0,他引:2
This is an introduction to a set of papers on Computer Ethics from the conference ETHICOMP95. Taken as a whole, the collection
of papers provides arguments and concepts to launch a new development in computer ethics: ‘Global Information Ethics’. A rationale
for globalization is provided, as well as some early efforts which move in that direction.
ETHICOMP95, an international conference on Computer Ethics, was held 28–30 March 1995 at De Montfort University, Leicester,
UK. Co-directors were Terrell Ward Bynum and Simon Rogerson. 相似文献

This paper outlines a prototype dual-purpose interface card for the IBM PC for use in research on motor learning and control. The card enables automatic interfacing for up to four angular optical encoders and presents high-speed visual data on an XY oscilloscope. In addition, it uses two single-chip microcontrollers with minimal external hardware, providing a more powerful instrument than is available in discrete hardware. Two microcontrollers operate independently of the experimental computer (IBM PC), using a common interface allowing the exchange of data. This interface card frees the experimental computer from the workload associated with optical encoders and high-speed XY displays, resulting in less complex experimental setups and data collection programs. 相似文献

During linear translation through a stationary environment, the pattern of optical flow generated on each retina is symmetrical when the head is aligned with the heading, but during lateral gaze the optical flow is asymmetric. We assessed whether human subjects could use the magnitude of this asymmetry to determine the direction of heading during passive translation through a 3-D environment. When allowed to move their heads in order to look in the direction of self-motion, subjects indicated their heading precisely and accurately. When the head was locked in alignment with the misaligned body, and gaze adjustments were not allowed, responses were quite precise, but showed a large bias which increased with increasing heading angle. 相似文献

A series of experiments investigated concurrent discriminations of surface and nonsurface attributes, including color, brightness, texture, length, location, and motion. In all cases but one, results matched those previously reported: Interference occurred when two discriminations concerned different objects, but not when they concerned the same one. In the two-object case, interference was the same whether discriminations were similar (e.g., two surface discriminations) or different (e.g., one surface, one boundary). Such results support a model of visual attention in which separate visual subsystems are coordinated, converging to work on surface and boundary properties of the same selected object. A partial exception is color: For reasons that are unclear, color escapes twoobject interference except from other, concurrent surface discriminations 相似文献

This study was designed to provide a detailed analysis of the parameters which interact to produce a field hockey drive. The drive was performed by an elite performer under two conditions of uncertainty (Blocked and Random). The subject was asked to drive a field hockey ball toward a specified target. In the Blocked condition the speed of the approaching ball remained constant (20, 30 and 40 m.p.h.) while in the Random condition these speeds were randomly assigned to each trial. Cine analysis of the subject's successful responses under the two experimental conditions led to an investigation of the kinematics, phasing, and timing of the stroke. The subject placed emphasis upon varying the initial phases of the stroke (i.e., backswing and preparatory phases) in order to produce a temporally consistent ballistic downswing to ball contact. It seemed likely that the subject appraised the ball speed that was being delivered and then incorporated additional stick movement to ‘mark time’ before initiating temporally consistent movement phases, as spatial uncertainty increased, the subject delayed her response initiation, but then tended to respond in intervals of one reaction time for each stroke phase. Consistency was evident for displacement and initiation point values, but to a lesser extent than existed for the other variables. However, as a result of this adjustment in spatial location and displacement of the stick end during the preliminary phases of the response, the subject was able to produce a consistent and accurate ballistic downswing. 相似文献

The paper reports four experiments concerned with memory for sets of categorically related or unrelated nouns, as a function of the extent to which initial processing focused on categorical or distinctive features of the nouns. The general finding is that distinctive features are valuable for later intracategory discrimination in recall and recognition, but categorical features are not, as judged by cued recall, recognition, measures of association between items, and categorical intrusion errors. A theoretical framework, based on the diagnostic value of features for various classifications, is offered as an account of the results. 相似文献

In an attempt to reconcile conflicting results concerning the effects of sexual arousal on interpersonal evaluations, hypotheses based on adaptation level, arousal-need gratification, and labeling of arousal explanations were tested. The variables of sexual arousal, technique of stimulus material presentation, physical attractiveness of the original stimulus female, and physical attractiveness of the final target person being judged were manipulated in a 2 × 2 × 2 × 2 design. A significant three-way interaction (Arousal × Stimulus Attractiveness × Target Attractiveness) obtained on all measures of interpersonal evaluation was interpreted as supporting a labeling of arousal explanation. It is suggested that subjects first interpret their arousal as being caused by their attraction toward the stimulus person. The characteristics of the stimulus person then become a factor used by subjects when they subsequently make judgments of target females. The adaptation-level and arousal-need gratification hypotheses were not supported. 相似文献
