This study was designed to assess the transfer of treatment gains of autistic children across settings. In the first phase, each of 10 autistic children learned a new behavior in a treatment room and transfer to a novel extra-therapy setting was assessed. Four of the 10 children showed no transfer to the novel setting. Therefore, in the second phase, each child who failed to transfer participated in an analysis of stimulus control in order to determine the variables influencing the deficit in transfer. Each of the four children who did not transfer were selectively responding to an incidental stimulus during the original training in the treatment room. Utilizing a reversal design, each of the four children responded correctly in the extra-therapy setting when the stimulus that was functional during training was identified and introduced into the extra-therapy setting. The extreme selective responding and the resulting bizarre stimulus control found are discussed in relation to the issue of setting generality of treatment gains. 相似文献

Nursing-home residents have frequently been characterized as unoccupied and disengaged. At the outset of the present study, most residents were to be found in their own rooms, not exhibiting gross motor behavior or social interaction, and not participating in appropriate activities. To modify residents' levels of participation with the environment, a manipulative area was provided in the lounge. Participation in the lounge averaged 20% on days when the activity was not available, but increased to a mean of 74% on days when equipment and materials were given and residents were prompted to participate. When prompts were withdrawn and materials were available only by request, mean participation fell to 25%. The findings demonstrate that manipulative activities can support a high level of participation with the environment, if residents are prompted to use equipment and materials. 相似文献

Unobtrusively marked items of litter were placed among existing trash on the grounds of a federal youth correctional facility. Inmates voluntarily collected trash and deposited it at a central location, where they were given money or special privileges for each piece of marked litter found. A multiple-baseline design with litter counts in three areas revealed successive reductions of 55%, 88%, and 71% after 17, 22, and 36 days of baseline, respectively. A fourth area served as a baseline-only control, and revealed no systematic changes. Advantages of the procedure over previously devised techniques were discussed and applications in other areas of pollution control suggested. 相似文献

The generalizability of behaviors across observational conditions is a critical issue in behavioral assessment. Generalizability theory was used to examine two aspects of audio recorded parent-child interactions recorded over 6 days of home measurement and 1 day of laboratory measurement in a behavioral treatment program for childhood obesity. Families audiotaped parent-child home meetings during which they reviewed self-monitored diet and exercise records that were coded for the following types of interactions: praise statements, negative statements, prompts for new behaviors, and statements promoting problem solving. A similar meeting was audiotaped in our laboratory. The first question explored was the number of measurements needed to generalize to the universe of the six home measures. Results showed an increase in generalizability over measurements for each behavioral category. Using generalizability coefficients of .60 or more, praise, negative comments and prompts, respectively, could be reliably observed based on 1, 4, or 4 days of measurement. Second, the effects of setting (laboratory versus home) were assessed for 1 day of measurement in each environment. Again using generalizability coefficients of .60, generalizability analysis showed that the lab setting could not be generalized to the home setting based on 1 day of measurement, with generalizability coefficients ranging from .27 for negative comments to .57 for praise. Results suggest that 4 days of behavioral assessment in the home can be used to establish generalizable data for all the dependent measures studied. However, generalizability coefficients suggested that 1 day of laboratory measurement was not adequate to generalize to typical home behavior.This research was supported in part by Grant NIH HD 23713 awarded to the third author. 相似文献

This report provides an experimental analysis of generalized vending machine use by six moderately or severely retarded high school students. Dependent variables were training trials to criterion and performance on 10 nontrained “generalization” vending machines. A multiple-baseline design across subjects was used to compare three strategies for teaching generalized vending machine use. Training occurred with (a) a single vending machine, (b) three similar machines, or (c) three machines that sampled the range of stimulus and response variation in a defined class of vending machines. Results indicated that the third approach was the most effective method of obtaining generalized responding. Methodological implications for the experimental analysis of generalization and programmatic implications for teaching generalized behaviors are discussed. 相似文献

In recent literature, the famous Millikan oil-drop experiment appears as a case of “good scientific judgment” on the one hand,
and scientific misconduct on the other. This article discusses different interpretations of the fact that Nobel laureate Robert
Millikan’s notebooks show that he eliminated a number of oildrops in his published 1913 paper on the charge of the electron,
while reporting that he had included all the drops. Starting with the common source of all Millikan stories, historian of
physics Gerald Holton’s 1978 paper, I discuss recent “canned” versions of Millikan-as-misbehaver in books on scientific fraud.
Then I examine some versions of Millikan-as-good-scientist, particularly the reconstruction by historian of physics Allan
Franklin, and the views of some practicing physicists. Finally, we have an instructive head-on collision between the two standard
treatments of Millikan. The problem with canned stories is not only insufficient information; we also lack a realistic evaluation
of the role of ethics in science. As a fundamentally knowledge-seeking enterprise, science may harbor an inherent, perhaps
irresolvable, conflict between scientific and ethical concerns.
The author’s special interests include standards for “good science”, science and values, and social psychology. 相似文献

Adequate Citation of data sets is crucial to the encouragement of data sharing, to the integrity and cost-effectiveness of
science and to easy access to the work of others. The citation behavior of social scientists who have published based on shared
data was examined and found to be inconsistent with important ideals of science. Insights gained from the social sciences,
where data sharing is somewhat customary, suggest policies and incentives that would foster adequate citation by secondary
users, and greater openness and sharing in other disciplines. 相似文献

ObjectiveIn this study, we aimed to understand the self-regulatory processes facilitating optimal experiences in running by integrating models of self-regulation with flow and clutch states.MethodUsing an event-focused approach, we interviewed 16 runners less than one day on average after recreational running activities (M = 22.17 hours later, range = 3–46) they described as positive, rewarding experiences. Our analysis drew on principles for thematic and connecting analyses.ResultsWe structured our analysis of the self-regulatory processes facilitating flow and clutch states into three overarching themes: forethought; monitoring; and control. Flow was facilitated by intrinsic experiential motives and non-specific goals, whereas clutch states involved an intrinsic motive to accomplish specific goals. The perceived ease and pleasure during flow motivated runners to continue this experience, which appeared to be aided by active and involuntary distraction. Conversely, clutch states were described as more effortful and less pleasant during the run, with active self-regulation strategies used to exert control over cognition and manage feelings of difficulty. Attending to specific outward or internal sensory stimuli appeared to initiate changes that contributed to the disruption of flow, although many runners described transitioning into a clutch state after flow disruption. No runner reported transitioning from a clutch state into flow.ConclusionsOur study offers novel insights into optimal experiences in running by integrating models of self-regulation with flow and clutch states. We discuss how these insights can inform research and applied practice seeking to develop interventions for promoting optimal experiences during running. 相似文献
