ABA renewal is a model of treatment relapse that describes the recurrence of severe problem behavior when behavior learned in one context (e.g., home; A) and treated in a separate context (e.g., clinic; B) reemerges when the original context is reintroduced (A). However, in the typical environment and during the usual course of treatment for severe problem behavior, the target behavior is exposed to the baseline context periodically (e.g., the child returns home after several hours in a clinic setting). Due to the difficulty of studying what effect this may have on treatment relapse during ABA renewal in a strictly applied investigation, we developed a human‐laboratory translation to study renewal in a nonsequential manner. Using undergraduate students as subjects, we directly compared levels of recurrence using the standard ABA renewal procedure and a modified nonsequential ACA procedure, one modeled from the typical course of treatment for problem behavior. Both methods produced renewal at comparable levels, and patterns during nonsequential ACA renewal were similar to those during sequential ABA renewal. We discuss the implications of these findings in the framework of treatment for severe problem behavior. 相似文献

Little is known about the impact of context on the meaning of emotion words. In the present study, we used a semantic profiling instrument (GRID) to investigate features representing five emotion components (appraisal, bodily reaction, expression, action tendencies, and feeling) of 11 emotion words in situational contexts involving success or failure. We compared these to the data from an earlier study in which participants evaluated the typicality of features out of context. Profile analyses identified features for which typicality changed as a function of context for all emotion words, except contentment, with appraisal features being most frequently affected. Those context effects occurred for both hypothesised basic and non-basic emotion words. Moreover, both data sets revealed a four-dimensional structure. The four dimensions were largely similar (valence, power, arousal, and novelty). The results suggest that context may not change the underlying dimensionality but affects facets of the meaning of emotion words. 相似文献

Based on the adaptive lie detector theory, this study is an examination of whether taking an oath, as context‐general information, increases the credibility of a suspect. The consistency of the testimonies of 6 eyewitnesses was manipulated so that it could be used as individuating information. There were 2 sets of testimonies: one that was consistent and one that was inconsistent. The results supported the adaptive lie detector theory. The participants judged those persons who took an oath to be more credible than those who did not, but this only happened in situations where the testimonies of the eyewitnesses were inconsistent. The theoretical and practical implications of the findings and future directions are then discussed. 相似文献

This study investigated processing effort by measuring peoples’ pupil diameter as they listened to sentences containing a temporary syntactic ambiguity. In the first experiment, we manipulated prosody. The results showed that when prosodic structure conflicted with syntactic structure, pupil diameter reliably increased. In the second experiment, we manipulated both prosody and visual context. The results showed that when visual context was consistent with the correct interpretation, prosody had very little effect on processing effort. However, when visual context was inconsistent with the correct interpretation, prosody had a large effect on processing effort. The interaction between visual context and prosody shows that visual context has an effect on online processing and that it can modulate the influence of linguistic sources of information, such as prosody. Pupillometry is a sensitive measure of processing effort during spoken language comprehension. 相似文献

Engineering educators have long discussed the need to teach professional responsibility and the social context of engineering
without adding to overcrowded curricula. One difficulty we face is the lack of appropriate teaching materials that can fit
into existing courses. The PRiME (Professional Responsibility Modules for Engineering) Project (http://www.engr.utexas.edu/ethics/primeModules.cfm) described in this paper was initiated at the University
of Texas, Austin to provide web-based modules that could be integrated into any undergraduate engineering class. Using HPL
(How People Learn) theory, PRiME developed and piloted four modules during the academic year 2004–2005. This article introduces
the modules and the pilot, outlines the assessment process, analyzes the results, and describes how the modules are being
revised in light of the initial assessment. In its first year of development and testing, PRiME made significant progress
towards meeting its objectives. The PRiME Project can strengthen engineering education by providing faculty with an effective
system for engaging students in learning about professional responsibility.
An earlier version of this paper was presented at the 2005 conference, Ethics and Social Responsibility in Engineering and Technology, Linking Workplace Ethics and Education, co-hosted by Gonzaga University and Loyola Marymount University, Los Angeles, CA, USA, 9–10 June 2005. 相似文献

Two experiments are reported in which the ratio of the average times spent in the terminal and initial links (Tt/Ti) in concurrent chains was varied. In Experiment 1, pigeons responded in a three-component procedure in which terminal-link variable-interval schedules were in constant ratio, but their average duration increased across components by a factor of two. The log initial-link response ratio was a negatively accelerated function of Tt/Ti. Overall, the data were well described by Grace's (1994) contextual choice model (CCM) with temporal context represented as (Tt/Ti)k or 2Tt/(Tt + Ti), and by Mazur's (2001) hyperbolic value-added model (HVA), with each model accounting for approximately 93% of the variance. In Experiment 2, fixed-parameter predictions for each model were generated, based on the data from Experiment 1, for conditions in which Tt/Ti was varied over a more extreme range. Data were consistent with the predictions of CCM with temporal context represented as 2Tt/(Tt + Ti) and to a lesser extent as (Tt/Ti)k, but not with HVA. Overall, these results suggest that preference increases as a hyperbolic function of Tt/Ti when terminal-link duration is increased relative to initial-link duration, with the terminal-link schedule ratio held constant. 相似文献

This study examined 5- and 6-year-olds' suggestibility and interviewer demeanor as joint predictors of their memory for a novel experience. Session 1 consisted of children taking part in a novel laboratory event. Session 2 took place after approximately a 1-week delay and consisted of children completing both a memory test concerning what happened during the prior event and the Video Suggestibility Scale for Children (VSSC). During the second session, the interviewer behaved either supportively or nonsupportively. Greater acquiescence on the VSSC was associated with fewer correct responses to misleading questions about the laboratory event in the supportive and nonsupportive conditions and with more errors in response to specific questions in the nonsupportive condition. Results indicate that individual differences in children's suggestibility are related to the accuracy of their memory for separate events, although some of these relations may vary depending on the context in which children are interviewed. 相似文献

This study examined how pigeons discriminate the relative frequencies of events when the events occur serially. In a discrete-trials procedure, 6 pigeons were shown one light nf times and then another nl times. Next, they received food for choosing the light that had occurred the least number of times during the sample. At issue were (a) how the discrimination was related to two variables, the difference between the frequencies of the two lights, D = nf - nl, and the total number of lights in the sample, T = nf + nl; and (b) whether a simple mathematical model of the discrimination process could account for the data. In contrast with models that assume that pigeons count the stimulus lights, engage in mental arithmetic on numerons, or remember the number of stimuli, the present model assumed only that the influence of a sample stimulus on choice increases linearly when the stimulus is presented, but decays exponentially when the stimulus is absent. The results showed that, overall, the pigeons discriminated the relative frequencies well. Their accuracy always increased with the absolute value of the difference D and, for D > 0, it decreased with T. Performance also showed clear recency, primacy, and contextual effects. The model accounted well for the major trends in the data. 相似文献

Three experiments examineed whether olfactory stimuli can produce context-dependent effects in infant memory. In eash, 3-month-old infants learned to kick to control the movement of an overhead modile in the presence of an ambient odor. Retention was assessed 1, 3, or 5 days later. During the retention test, the olfactory context was either the same odor, a different odor, or “no odor.” At 1 day, infants exhibited retention when tested in the presence of the same odor. Infants in the no odor condition exhibited partial retention, whereas memory retrieval was completely disrupted for infants tested in the presence of the different odor. After the 3- and 5-day intervals, all groups showed forgetting. These results were not consistent with recent studies of 3-month-old infants trained and tested in the presence of a distinctive visual and auditory context. The findings suggest that olfactory stimuli are a silent feature of the environment for 3-month-old infants, but that they function as context cues in a way that differs from other sensory modalities. 相似文献

We wished to identify predictors of family functioning from models including perceptions of stresses associated with mobility, financial compensation, intrusiveness to family boundaries, expectations on time demands, and the lack of social support. Data were collected from 136 randomly selected couples from six denominations in which husbands were clergy. Participants completed a survey that included the Clergy Family Life Inventory which assessed perceptions of five work-related stressors and the Self Report Measure of Family Functioning scale which measured 12 dimensions of family functioning. Separate regression models were tested for husbands and wives and these analyses indicated that no single stressor seemed influential for all 12 dimensions of family functioning. However, for both husbands and wives, family boundary intrusiveness, lack of social support, and mobility stresses influenced their competence in numerous areas of family functioning. In addition, husbands and wives experienced similar effects of stress among several dimensions of family functioning (e.g. enmeshment, family organization, democratic family atmosphere expressiveness). 相似文献
