Being culturally disadvantaged is a social condition which is created, managed, and maintained by both social and professional institutions. When institutions attempt to sustain societal norms by selecting certain attributes and calling them desirable, these institutions are relegating large segments of the population to a deviant status if it does not share these attributes. The “culturally disadvantaged” are such a group. This phenomenon not only results in differential perceptions and expectations, but also influences their self-evaluation, academic success, and career opportunities. The transformation of deviance into incompetency has also led to formally sanctioned methods of managing deviancy. Methods, such as compensatory education, ability grouping, and special class placement can be viewed as maintaining the position that the culturally disadvantaged are indeed deviant and incompetent. 相似文献

In 3 experiments, participants, on signal, moved a cursor from a central position to 1 of 8 numerically labeled locations on the circumference of a clock face. Movements were controlled by a mouse in 1 of 4 conditions: vertical reversal, horizontal reversal, combined reversals, or normal (i.e., no reversals). Participants were trained in 1, 2, or 3 of these conditions and were tested 1 week later with either the same or a different condition. There were improvements across training and perfect retention across the delay. There was little or no transfer, however, even when training involved combined reversals or multiple conditions. These results illustrate severe specificity of training and are interpreted in terms of acquired inhibition of normal responses. 相似文献

The phenomenon of perceptual persistence after the motion stops in shape-from-motion displays (SFM) was used to study the influence of prior knowledge on the maintenance of a percept in awareness. In SFM displays an object composed of discontinuous line segments are embedded in a background of randomly oriented lines. The object only becomes perceptible when the line segments that compose the object and the lines that compose the background move in counterphase. Critically, once the movement of the line segments stops, the percept of the object persists for a short period of time. In the present study, perceptual persistence for digits exceeded that reported for nonsense shapes composed of the same line segments. This result is taken as evidence that the processes involved in the persistence of SFM, and therefore sustained perception, are sensitive to top-down influences. 相似文献

The Accreditation Board of Engineering and Technology (ABET) has declared that to achieve accredited status, “engineering
programs must demonstrate that their graduates have an understanding of professional and ethical responsibility.” Many engineering
professors struggle to integrate this required ethics instruction in technical classes and projects because of the lack of
a formalized ethics-in-design approach. However, one methodology developed in human-computer interaction research, the Value-Sensitive
Design approach, can serve as an engineering education tool which bridges the gap between design and ethics for many engineering
disciplines. The three major components of Value-Sensitive Design, conceptual, technical, and empirical, exemplified through
a case study which focuses on the development of a command and control supervisory interface for a military cruise missile. 相似文献

V. M. Sloutsky and A. V. Fisher reported 5 experiments documenting relations among categorization, induction, recognition, and similarity in children as well as adults and proposed a new model of induction, SINC (similarity, induction, categorization). Those authors concluded that induction depends on perceptual similarity rather than conceptual knowledge. Despite the useful contributions of this work, there are some important limitations. The experimental designs examined a limited range of phenomena that are not the most revealing about the use of nonperceptual information. The main results involved a simple triad task, for which the SINC model's predictions are equivalent to the predictions of previous models of inductive reasoning. It is also unclear whether the SINC model can account for the observed relations between similarity and recognition. Implications for future work on induction and related cognitive activities are discussed. 相似文献

In 2 experiments we assessed younger and older adults' ability to remember contextual information about an event. Each experiment examined memory for 3 different types of contextual information: (a) perceptual information (e.g., location of an item); (b) conceptual, nonemotional information (e.g., quality of an item); and (c) conceptual, emotional information (e.g., safety of an item). Consistent with a large literature on aging and source memory, younger adults outperformed older adults when the contextual information was perceptual in nature and when it was conceptual, but not emotional. Age differences in source memory were eliminated, however, when participants recalled emotional source information. These findings suggest that emotional information differentially engages older adults, possibly evoking enhanced elaborations and associations. The data are also consistent with a growing literature, suggesting that emotional processing remains stable with age (e.g., Carstensen & Turk-Charles, 1994, 1998; Isaacowitz, Charles, & Carstensen, 2000). 相似文献

According to the diversity principle, diverse evidence is strong evidence. There has been considerable evidence that people
respect this principle in inductive reasoning. However, exceptions may be particularly informative. Medin, Coley, Storms,
and Hayes (2003) introduced a relevance theory of inductive reasoning and used this theory to predict exceptions, including
the nondiversity-by-propertyreinforcement effect. A new experiment in which this phenomenon was investigated is reported here.
Subjects made inductive strength judgments and similarity judgments for stimuli from Medin et al. (2003). The inductive strength
judgments showed the same pattern as that in Medin et al. (2003); however, the similarity judgments suggested that the pattern
should be interpreted as a diversity effect, rather than as a nondiversity effect. It is concluded that the evidence regarding
the predicted nondiversity-byproperty-reinforcement effect does not give distinctive support for relevance theory, although
this theory does address other results. 相似文献

Using experiences at Memorial University of Newfoundland as a basis, this essay suggests that leadership should be an expectation of professional academics in all the categories of their work, namely teaching, research and service. The desirability of developing the leadership of service in particular is advanced as an appropriate expectation for faculty members career progress. Developing a general leadership ethos is both philosophically appropriate and practically advantageous in collegial organisations. 相似文献

In two experiments, the response signal technique (Reed, 1973) was combined with the DRM paradigm (e.g., McDermott & Roediger,
1998) to investigate the time course of false recognition memory— in particular, how this effect varies along the time course
of generating a recognition judgment. Across the experiments, in addition to standard instructions, there were forewarning
instructions encouraging the participants to avoid this effect, as well as inclusion instructions intended to enhance this
tendency. It was found that the false memory effect was at its strongest at earlier response signals, diminishing when more
time was given to make a recognition judgment. The forewarning instructions led to a more conservative overall response bias,
rather than to a reduction of the effect. However, the participants were able to exaggerate this effect in the inclusion condition.
The results are discussed in terms of the role of strategic processing in recognition memory. Part of this research was presented
at the 42nd Annual Meeting of the Psychonomic Society, Orlando, in November 2001. It was supported by a grant from the Biotechnology
and Biological Sciences Research Council of the United Kingdom. 相似文献

Traditional process models of old-new recognition have not addressed differences in accuracy and response time between individual stimuli. Two new process models of recognition are presented and applied to response time and accuracy data from 3 old-new recognition experiments. The 1st model is derived from a feature-sampling account of the time course of categorization, whereas the 2nd model is a generalization of a random-walk model of categorization. In the experiments, a new technique was used, which yielded reliable individual-stimulus data through repeated presentation of structurally equivalent items. The results from the experiments showed reliable differences in accuracy and response times between stimuli. The random-walk model provided the better account of the results from the 3 experiments. The implications of the results for process models of recognition are discussed. 相似文献
