A model is described for implementing a program in research ethics education in the face of federal and institutional mandates and current resource, disciplinary, and infrastructure limitations. Also discussed are the historical background, content and evaluation process of the workshop at the heart of the program, which reaches a diverse group of over 250 students per year—from first-year graduate students in basic research labs to clinical fellows. The workshop addresses central issues in both everyday laboratory ethics and in larger societal questions. Goals include improving overall awareness of ethics guidelines and philosophy and enhancing skills in identifying and then analyzing the ethical components of situations. Pedagogies used and their effectiveness and that of the overall workshop and extended program are addressed. Programs like these have initiated a shift in the culture of basic research, which is a critical need given the current atmosphere.  相似文献

The effects of age, modeling, tuition, and sanctions on self-control of motor behavior were examined. Children 6, 7, 9, and 11 years of age individually participated. A male model either: (a) instructed and performed “Simon Says” in the traditional manner, (b) introduced the sanction “Don't” on the inhibition trials, (c) performed an action that differed from the instruction, or (d) gave instructions only. Activation latency and inhibition error were influenced most greatly by the actions of the model and the introduction of a negative sanction, whereas tuition was less effective. Age differences were present for inhibition errors as well as activation latency and error. The discussion focused on the differential effects of modeling and tuition on deviant responding.  相似文献

In the first study subjects were given information about an applicant to graduate school and asked to rate his qualifications. The information experimentally varied (a) whether the school had an affirmative action policy, (b) the ethnicity of the applicant, and (c) whether the applicant was accepted or rejected. Based on Kelley's discussion of the discounting and augmentation principles, it was predicted that the minority applicant would be rated as less qualified when the university was committed to an affirmative action program. The reverse pattern was predicted for the non-minority applicant. The results supported the first prediction but not the second. Experiment 2 was designed to eliminate alternative interpretations of the data and the same results were found. Possible interpretations for the failure of affirmative action in affecting the ratings of nonminority applicants are discussed.  相似文献

This study examined the effects of a senior high school suicide prevention unit on students' levels of stress, anxiety, and hopelessness. An experimental group that received instruction in suicide prevention, and that demonstrated special needs, i.e. low social support, high stress, high anxiety, and/or high degrees of hopelessness, was compared with an experimental group that did not demonstrate special needs, and with two control groups that received no instruction, one with, and one without, special needs. Results indicated that both the experimental group with special needs and the experimental group without special needs showed significant increases in factual knowledge; the experimental group with special needs showed significant change on psychological variables, while the control group with special needs did not. No significant differential changes were noted between the experimental group with special needs and the control group with special needs. Implications for counselling psychologists are considered.  相似文献

This study examined the effect of tonal location on the discrimination of sequences differing in the order of the tones and on their perceived grouping. The frequency range between the sequential tones was held constant. When all tones came from the same location, the sequence was rated as integrated, but when the higher frequency tones came from a different location than the lower frequency tones, the sequence was rated as segregated. Listeners discriminated the sequences in a 3EFC task. Discrimination performance was impaired when the sequence was split between two locations and tonal order was changed in only one location, even though the order of tones in different locations was changed. This result suggests that listeners have difficulty relating tones across locations or in different perceptual groups. Performance in this experiment is generally better than that observed by Barsz (1988), and it is suggested that the level of stimulus uncertainty explains this difference.  相似文献

Despite nationwide efforts to professionalize public-school teaching, little attention has been given to the matter of standards of professional conduct for teachers. The authors examined teachers' perceptions of the frequency and seriousness of different categories of teacher misconduct. They administered a 34-item questionnaire to 235 school professionals in northwestern South Carolina. For each item, respondents rated the extent to which they agreed or disagreed that the behavior occurred frequently and represented a serious violation of professional ethics. Factor analysis of the ratings of seriousness yielded 3 domains of ethical concerns: (a) student-teacher boundary violations, (b) carelessness in behavior, and (c) subjectivity in grading and instruction. Teachers rated boundary violations as the most serious but least common violations and carelessness in behavior as the most frequent but least serious violation. Problems of subjectivity in grading were rated as moderately frequent and moderately serious. The authors found no differences between male and female teachers or between elementary and secondary teachers in their ratings of the seriousness or frequency of any of the 3 groups of ethical concerns. The authors discuss implications for development of a national code of teacher conduct.  相似文献

The relative effects of developmental level and domain-specific knowledge on children's ability to identify and make similarity decisions about object concepts based only on haptic (touch) information were investigated. Children aged 4-9 years with varying levels of dinosaur knowledge completed a cross-comparison task in which they haptically explored pairs of familiar (dinosaur) and unfamiliar (sea creature) models that varied in terms of their degree of differentiability. Older children explored models more exhaustively, found more differentiating features and consequently made fewer errors than younger children did. High knowledge enabled children to identify models correctly, but was also associated with the use of a hypothesis testing strategy, which led children to make greater numbers of "miss" errors on the cross-comparison task. Performance in the control domain illustrated that the hypothesis testing strategy was specific to the high knowledge domain. Potential explanations for the role of knowledge and development in haptic exploration are considered.  相似文献

An analysis of the relationship among the Personality Assessment Inventory (PAI; Morey, 1991, 1996) Drug Problems (DRG) scale scores, the Addiction Severity Index (ASI; McLellan et al., 1992) scores, and urine toxicology reports revealed that the PAI Drug Problem scale scores of 100 substance-using and substance-abusing men and women were distributed in a manner that was in agreement with the guidelines suggested by Morey (1991, 1996) in the PAI manual. There were significant correlations among the PAI DRG scale and the ASI scales related to frequency of use, negative consequences of use, and need and desire for treatment. Overall, higher scores did reflect both more serious involvements with drug use and more serious problems as a consequence of their involvement.  相似文献

We examined the effect of visual experience on the haptic Müller-Lyer illusion. Subjects made size estimates of raised lines by using a sliding haptic ruler. Independent groups of blind-folded-sighted, late-blind, congenitally blind, and low-vision subjects judged the sizes of wings-in and wings-out stimuli, plain lines, and lines with short vertical ends. An illusion was found, since the wings-in stimuli were judged as shorter than the wings-out patterns and all of the other stimuli. Subjects generally underestimated the lengths of lines. In a second experiment we found a nonsignificant difference between length judgments of raised lines as opposed to smooth wooden dowels. The strength of the haptic illusion depends upon the angles of the wings, with a much stronger illusion for more acute angles. The effect of visual status was nonsignificant, suggesting that spatial distortion in the haptic Müller-Lyer illusion does not depend upon visual imagery or visual experience.  相似文献
