We investigated whether variations in alertness among individuals with profound multiple disabilities affected subsequent responsiveness to training programs. Three experiments were conducted involving 5 people. In Experiment 1, results indicated that alertness of 3 individuals increased with provision of skill-acquisition training programs. Results also indicated no predictive relationship between alertness levels prior to training and subsequent responsiveness to training. Experiment 2 replicated results of Experiment 1 with 2 participants from Experiment 1 and an additional participant. Results of Experiment 2 also indicated that the increased alertness levels accompanying provision of training were not a function of the participants simply being in an inactive environment prior to training. Results of Experiment 3 indicated that alertness of an additional participant increased through provision of another training intervention, involving a systematic preference assessment. Responses during the preference assessment appeared to be unrelated to previously existing alertness levels. These findings suggest the need for caution when considering the withholding of scheduled training because an individual appears to be nonalert. 相似文献

We evaluated a means of increasing staff members' interactions with an individual with multiple disabilities through use of a voice output communication aid (VOCA). When activated, the VOCA allowed the individual to communicate through synthesized speech. Results indicated that staff members interacted with the individual more frequently when she had access to the VOCA, suggesting that VOCAs may represent an alternative to more traditional staff management programs for increasing interactions. 相似文献

The effects of functional communication training, extinction, and response chaining on 3 subjects' escape-maintained aberrant behavior were evaluated using a multielement design. Functional communication training consisted of teaching subjects a verbal response that was functionally equivalent to their aberrant behavior. Subjects initially were allowed to escape from a task contingent on the trained verbal response. In subsequent treatment phases, escape was contingent on the trained verbal response plus the completion of the specified number of steps in the task (response chaining). The number of steps was increased until a subject completed the task to obtain a break. Results showed that the treatment reduced rates of aberrant behavior and that the chaining procedure was effective in decreasing the availability of escape. 相似文献

There are at least two qualitatively different types of subjective experience that can accompany accurate recognition memory. Sometimes recognition is accompanied by conscious recollection of the learning episode (i.e., it isremembered), and in other cases it is not (i.e., it is simplyknown that the item is old). In the present study, we assessed the subjective experience that accompanies crossmodality confusion errors (misidentifying words as pictures) by measuring the extent to which subjects claimed toremember versusknow that the item was presented as a picture. The results of two experiments demonstrate that cross-modality confusion errors are often accompanied by conscious recollection, although not to the same extent as accurate memories. The findings also show that there is considerable overlap in the recollective experience that accompanies accurate and erroneous memories. Finally, the results support the contention that recollective experience cannot be directly inferred from test performance. 相似文献

This study considers how high school students perceive incidents of possible sexual harassment toward students and how they define sexual harassment. Thirty-five male and 38 female high school seniors (44% Asian-American; 40% white, non-Hispanic; 6% Indian-American; 4% African-American; 3% Hispanic; and 3% other ethnic groups) evaluated scenarios that varied the type of sexual harassment, the status of the initiator (either teacher or student), and the gender composition of the dyad (either male toward female or female toward male). As predicted, type of harassment influenced ratings of severity. Compared to male respondents, female respondents rated the scenarios as more severe. Teachers were judged more critically than students. Differences in status were more apparent at less severe levels of harassment. In defining harassment, students relied on four factors: the behavior itself, the target's reaction to the behavior, the perpetrator's intentions, and the relationship that existed between the two people. Overall, the findings underline the importance of examining high schools as a locale for harassment.This study was originally conducted by the first author as a Westinghouse Science project at Stuyvesant High School, with the guidance of the second and third authors. 相似文献

Prevalence of ADHD and comorbid disorders among elementary school children screened for disruptive behavior 总被引:8,自引:0,他引:8

In the context of a school-based prevention of conduct disorder program, 7,231 first- through fourth-grade children were screened for cross-setting disruptive behavior. Frequencies of DSM-III-R psychiatric disorders and patterns of comorbidity were assessed. We also examined the association of psychiatric diagnosis with child and parent characteristics to determine differential risk based on diagnostic subgroups. Attention deficit hyperactivity disorder (ADHD) and oppositional-defiant disorder (ODD) were the most frequent diagnoses. Mood and anxiety disorders were infrequent as single diagnoses. Patterns of comorbidity demonstrated that both externalizing and internalizing disorders commonly cooccurred with ADHD. More severe degrees of psychopathology and psychosocial risk accrued to the subgroup of youths with ADHD plus a comorbid externalizing disorder.This study was supported by grant MN-46584 from the National Institute of Mental Health. 相似文献

The variability of the information on which a belief was initially based should moderate the degree to which the belief is revised when new disconfirming information is received. Reasoning from everyday intuitions, psychological theories of concept representation, and a rational mathematical analysis, we inferred that as variability increased, resistance to disconfirming information would also increase. Participants’ judgments of the central tendencies of distributions of numerical information confirmed this prediction. 相似文献

Five foster grandparents were taught training skills for use in their daily interactions with severely handicapped persons in an institution. Following baseline, specific teaching procedures consisting of teacher instructions, prompts, modelling, and praise were implemented. The grandparents' frequency of training three skill areas increased as the specific teaching was implemented in multiple-baseline format. The total amount of training continued as teacher instructions, prompts, and modelling were terminated and praise continued, although the grandparents spent their training time emphasizing only two of the three skill areas. Teacher presence was gradually reduced over an 11-week period, with no decrease in grandparents' frequency of training. Four of the foster grandchildren, all profoundly retarded and multiply handicapped, demonstrated progress throughout the study. Results were discussed in light of the available contributions of foster grandparents in institutional settings and maintenance of staff training. 相似文献
