A high-probability request sequence was implemented with three preschool children with developmental delays within their classroom during typical activities. A multiple baseline design across subjects was used to evaluate the effects of the high-probability request sequence on compliant responding to low-probability requests and the occurrence of disruptive behavior. Results of the study indicate that the use of the high-probability request sequence was effective in increasing compliant responding to low-probability requests delivered by two different trainers for all children. No increases in disruptive behavior were noted as a result of using the high-probability request sequence. When the high-probability request sequence was withdrawn, compliant responding to low-probability requests was maintained for all children across time and in different settings.  相似文献

Formalizing shared ethical standards is an activity of scientific societies designed to achieve a collective goal of promoting ethical conduct. A scientist who is faced with the choice of becoming a “whistleblower” by exposing misconduct does so in the context of these ethical standards. Examination of ethics policies of scientific societies which are members of the Council of Scientific Society Presidents (CSSP) shows a breadth of purpose and scope in these policies. Among the CSSP member societies, some ethics policies chiefly present the ethical culture of the community in an educational context and do not have enforcement procedures. Other policies are more comprehensive and include standards for certification, procedures for addressing ethical issues, and established sanctions. Of the 36 member societies of CSSP that have developed a code or adopted a code of another professional society, 18 specifically identified a responsibility to expose ethical misconduct, demonstrating an acknowledgment of the possible critical role of the whistleblower in addressing ethical issues. Scientific societies may revise their ethics codes based upon experience gained in addressing cases of ethical misconduct. In most cases, the action of a whistleblower is the initial step in addressing an ethics violation; the whistleblower may either be in the position of an observer or a victim, such as in the case of someone who discovers that his or her own work has been plagiarized. The ethics committee of a scientific society is one of several possible outlets through which the whistleblower can voice a complaint or concern. Ethical violations can include falsification, fabrication, plagiarism and other authorship disputes, conflict of interest and other serious violations. Commonly, some of these violations may involve publication in the scientific literature. Thus addressing ethical issues may be intertwined with a scientific society’s role in the dissemination of new scientific results. For a journal published by a scientific society, the editor can refer at some point to the ethics committee of the society. Whereas, in the case of a journal published by a commercial publisher, the editor may be without direct support of the associated scientific community in handling the case. The association of a journal with a scientific society may thus direct a whistleblower towards addressing the issue within the scientific community rather than involving the press or talking to colleagues who may gossip. A formal procedure for handling ethics cases may also discourage false accusers. Another advantage of handling complaints through ethics committees is that decisions to contact home institutions or funding agencies can be made by the ethics committee and are not the responsibility of the whistleblower or the editor of the journal. The general assessment is that the establishment of ethics policies, especially policies covering publication in society journals, will promote a culture supportive of whistleblowers and discouraging to false accusers. An earlier version of this paper was presented at the symposium entitled “Damned If You Do, Damned If You Don’t: What the Scientific Community Can Do About Whistleblowing” held during the Annual Meeting of the American Association for the Advancement of Science, Seattle, Washington, 15 February, 1997.  相似文献

The self-perception explanation of the foot-in-the-door technique suggests that a person who complies with a small request infers that he or she is the kind of generous individual who is more likely to comply with a larger demand. It was hypothesized that individuals who are promised a monetary reward for their compliance with a small request are not more likely to comply with a larger demand because they cannot perceive themselves as generous persons. To test this hypothesis, subjects were presented with a small request (a 5-minute telephone interview) followed, 2 or 3 days later, by a larger demand (a 25-minute telephone interview). Some of the subjects were promised a monetary reward for their compliance with a small request (pay condition) while others were not promised a reward (no-pay condition). Results showed that rate of compliance in the no-pay conditon (64.3%) was significantly higher than rate of compliance in either a no-initial-request control condition (45.0%) or the pay condition (33.3%). The difference in rate of compliance between the control condition and the pay condition was not significant.  相似文献

Longitudinal data collection designs are frequently used in the study of developmental variables but typically yield patterns of results that are different from those obtained using cross-sectional designs. Recent research has focused on ways to clarify and reconcile the methodological distinctions between these two designs by utilizing alternative designs that incorporate features of both. This investigation compared the results obtained by the two traditional designs on the Career Maturity Inventory-Attitude Scale with the effects of an alternative design: constructing a composite longitudinal gradient. The two traditional methodologies yielded different results from each other for males, but not for females. However, the alternative design failed to eliminate the obtained differences for males, and introduced differences for females, casting doubt on the efficacy of the “solution.” The implications of these results for developmental research and career maturity were discussed.  相似文献

Memory span for pictures of common objects and for the names of these objects was examined as a function of three speech-related variables. Both picture span and name span were found to be influenced by the phonological similarity (Experiment 1) and the length (Experiment 2) of the names, as well as by the subject’s engaging in “irrelevant” vocalization during item presentation (Experiment 3). Moreover, for each variable the effect was in the same direction and of comparable magnitude for the two types of items. Experiments 4-6 replicated these findings with the procedure modified such that the retention of order information was not required. It is concluded that under the present conditions, there is a substantial functional equivalence between short-term memory for readily nameable pictures and for words and that this equivalence may be thought of as due to mediation by a common, “speech-like” code.  相似文献

Six differences in linguistic behavior in same-sex and mixed-sex problem-solving groups were explored. Small groups of all women, all men, and mixed sex were run and videotaped. Linguistic behavior was assessed through a content analysis of four syntactic categories: intensifiers, modal constructions, tag questions, and imperative constructions in question form. Support was found for the hypothesis of Key (1975) and Lakoff (1975) that women, as compared with men, use more linguistic categories that connote uncertainty. Support was also found for these authors' hypotheses that (1) women use more linguistic forms that connote uncertainty when men are present than when men are absent, and (2) men are more likely to interrupt women than women are likely to interrupt men. The results are discussed from the perspectives of women's role (supportive behavior and minority status) and women's culture (interpersonal sensitivity and emotionality).This report is a revision of a paper presented at the Pioneers for Century III Conference, Cincinnati, Ohio, April 1976.  相似文献

The purpose of this study was to demonstrate the applicability of Fitts' law in predicting the response duration of instruction-specific head movements for a person with severe multiple disabilities. Fitts' law is a motoric algorithm that calculates an index of difficulty (ID) for responses in relation to the variables of stimulus width and stimulus amplitude. Four functional tasks from the learner's current continuing education plans were targeted: photocopying, using a paint well, model painting, and communication symbol sequencing. For each of the four tasks, two sets of indices were calculated by (1) holding constant stimulus width while varying amplitude, and (2) holding constant stimulus amplitude while varying width. Results showed that response duration varied as a function of ID variation.  相似文献

Innovations in software for the analysis of eye movements have not kept pace with the development of hardware for collecting samples of eye position (Scinto & Barnette, 1986). Eye fixation and duration have been the primary measures for gleaning knowledge of subjects’ performance while the subjects are engaged in cognitive visual tasks. The program Cluster was developed as a means of investigating the dynamics of target examination characteristics that do not lend themselves to traditional methods of eye-movement analysis. This tool has proved to be a valuable means of assessing visual activity at a micro level, in comparison with the gross measures of distribution of visual attention in various areas of the visual field. In this report, we describe the history surrounding the development of Cluster as an analytical tool, the source of input required for its execution, the mechanics of the execution as an interactive process, the replicability of raters’ judgments, the program’s products of visual displays and data file output, and the potential application of such a tool for analyzing visual activity.  相似文献

Although irrationality has been consistently correlated with the intensity of acute clinical syndromes that are characterized by emotional or thought disorders, relationships between irrationality and personality disorders have not been investigated carefully. When they enter treatment, clients at the Institute for Rational-Emotive Therapy (IRET) had personality trait scale scores that accounted for substantial variance in rationality scale scores on several well-validated instruments. The eleven scales of the Millon Clinical Multiaxial Inventory (MCMI) associated with the DSM-III axis II personality disorders had a pattern of relationships with rationality and irrationality that parallels their somewhat surprising relationships with measures of acute emotional distress. Scales 4, 5, 6, and 7 were almost always associated with hyperrationality on most scales and with enhanced self-esteem, as well as with relatively low distress; scales 1, 2, 3, 8, S, and C were associated with irrationality and low self-esteem, as well as with severe distress. The P scale had inconsistent and weak correlations with rationality and self-esteem, as it had with measures of intake distress.Russell C. Leaf is Associate Professor of Psychology at Rutgers.
