The utility of teacher judgment (rankings, ratings) and peer judgment (sociometric ratings) were studied as screening variables for preschool social withdrawal/responsiveness. Observational measures of preschoolers' interaction were used as the validation criterion based upon theoretical, empirical, and practical considerations related to development of a multipurpose behavioral assessment system. Results indicated that teacher rankings of students' verbal interaction frequencies (1) were most highly correlated to interaction rate in two preschool settings, (2) had test-retest reliability consistently above Rho = .80, and (3) were useful in that 77% of teachers using this procedure could identify their least socially responsive student within five rankings. The peer nomination sociometric rating was the least reliable measure at retest (Rho = .35) and showed consistently the lowest correlation with observational indices of interaction partner preferences, e.g., reciprocal rate (Rho = .29 to .39). The tendency for relationships among screening measures and the criterion to increase at retest suggested a training effect on screening accuracy. The use of teacher rankings in combination with observational measures to confirm selection accuracy and for monitoring treatment progress is discussed as a cost-effective behavioral assessment procedure for preschool social withdrawal/responsiveness. 相似文献

Hyperactive boys on methlyphenidate (Ritalin), hyperactive boys on placebo, and comparison boys were observed in quasi-naturalistic classroom settings. Ambient stimulation (quiet versus noisy conditions) and source of regulation (self-paced versus other-paced activities) were varied in a 2 × 2 design. Compared to their peers, hyperactive boys on placebo showed lower rates of task attention and higher rates of gross motor movement, regular and negative verbalization, noise-making, physical contact, social initiation, disruption, and acts that were perceived as energetic, inappropriate, or unexpected. Self-paced activities resulted in increased rates of verbalization, social initiation, and high-energy episodes. High ambient noise levels reduced task attention and increased the rates of many other behaviors including verbalization, physical contact, gross motor movement, and high-energy acts. Medication-by-situation interactions emerged for both classroom dimensions, with hyperactive boys on placebo being readily distinguishable from their peers under some classroom conditions and indistinguishable under other conditions. Moderate relationships were found between teacher ratings and many individual behavior categories. Discussion focused on (a) the merits and limitations of a social ecological research perspective, and (b) the implications of these findings for the design of intervention strategies. 相似文献

Peer tutoring—academic instruction given by a student to a same-aged classmate—can be a cost-effective way of providing needed instruction in the typical classroom where one teacher must deal with many students of varying ability levels. This study evaluated an instructional package as a training method for increasing the use of selected tutoring behaviors by peer tutors. Nine male students, aged 7 to 9 years, from a learning disabilities resource room served as subjects; four subjects served as tutors, four as students, and one as a generalization student who was assigned to all tutors during generalization testing. Subjects were assigned to tutor-student pairs based on their performances on a pretest of the 220 Dolch Basic Sight Words, with the subjects scoring highest on the pretest serving as tutors. Each tutor worked with his assigned student throughout the study, except for pre- and posttest sessions with the generalization student. During daily sessions, tutors trained their students to recognize sight words using 10 flash cards, each with 1 of the Dolch words printed on it. Training was conducted with all four tutors in a group and was evaluated using a multiple baseline design across three classes of tutoring behaviors: Preparation Behaviors, Prompting Behaviors, and Praising Behaviors. Training consisted of: (a) verbal instructions on how to perform the tutoring behaviors; (b) charts illustrating the appropriate tutoring behaviors with stick figures; (c) role playing with each tutor with the experimenter playing the part of the student and giving feedback and verbal reinforcement to the tutor for performance of the appropriate tutoring behaviors; and (d) verbal testing of each tutor by asking him to state orally the behaviors he was to perform. Training sessions took approximately 30 minutes for each of the 3 classes of tutoring behaviors. Results showed an increased use of tutoring behaviors by tutors as a function of the instructional package. Increases in tutoring behaviors were also observed during postintervention generalization testing of tutors instructing their regular student in new subject matter (math). Data taken from pre-, mid-, and postintervention testing of the 220 Dolch Words showed an increase of identifiable sight words by both students and tutors after completing the peer tutoring program. This study demonstrates that a simple tutor training package can be employed to teach young, special education students to serve as effective tutors for their peers. In addition, the academic gains evidenced by the subjects lend positive support to the effectiveness of peer tutoring programs and specifically to the research of Dineen, Clark, and Risley (Journal of Applied Behavior Analysis, 1977, 10 , 231–238) which demonstrated the educational benefits of tutoring incurred by the tutor as well as by the student. 相似文献

Twenty-nine insomniacs underwent four consecutive sleep laboratory evaluations before and after receiving tension-release relaxation training, no-tension-release relaxation training, or no-treatment. On the basis of the discrepancy between subjective and EEG-defined measures of latency to sleep onset, subjects were classified as pseudoinsomniacs or idiopathic insomniacs. As predicted, tension-release relaxation was significantly more effective than the other two conditions on subjective sleep measures, regardless of insomnia subtype and on objective sleep measures only for idiopathic insomniacs. Subjective improvement was maintained at 12-month followup. Numerous differences between the two subtypes emerged on pretherapy and during-therapy measures distinct from the latency measures, but changes on those variables were unrelated to outcome improvement. 相似文献

Institutional breakfast-serving procedures were manipulated to assess what effect changes in that aspect of the environment would have on requests for food. During baseline, six severely retarded children were required to pick up their food trays and return to their seats. The first manipulation, delaying the giving of the food tray for 15 seconds, served as a cue to evoke meal requests by three of the six children. Two of the remaining three required a model of an appropriate meal request (i.e., “Tray, please.”) at the end of the 15-second delay before they began requesting their meals. To evoke meal requests from the sixth child, an intensive training procedure, consisting of massed trials of delay and modeling, was required. Three different probes were administered to assess generalization across the people serving the meals, across mealtimes, and across both people and mealtimes. Typically, generalized responding in these new situations could be prompted by use of the 15-second delay procedure. Functional aspects of the delay procedure and its potential usefulness for evoking speech and facilitating generalization are discussed. 相似文献

Children were trained on a visual discrimination by stimulus shaping, stimulus fading, or trial-and-error. Those who did not acquire the conditional discrimination received a second, different training. More children initially trained by stimulus shaping acquired the conditional discrimination than did those initially trained with stimulus fading or trial-and-error. After a history of fading or trial-and-error training, children were less likely to acquire the conditional discrimination even after the more successful procedure of shaping was later used. 相似文献

The biomotometer, an electronic device that simultaneously measures activity and provides auditory feedback to the subject, was used in combination with material reinforcers in two experiments attempting to modify activity level in children. In the first study the activity level of an 11-year-old highly active boy was decreased below mean baseline during conditioning in a classroom setting. His level of activity returned to baseline when feedback was withdrawn. In the second study, activity level of a 10-year-old hypoactive boy was increased over mean baseline level during conditioning in a free-play setting, and returned to slightly below baseline during five extinction trials. Results of these studies indicate that the biomotometer is a useful instrument for modification of activity level. 相似文献

The present study investigated relationships between self-esteem (SE) and job satisfaction among black and white employees. The sample consisted of 523 (45% black) employees of a large, urban school system. There was a positive relationship between SE and job satisfaction for members of both racial groups. In addition, the correlation between need satisfaction and job satisfaction was stronger for high SE persons than for low SE persons. The relationships between two social reference variables (the perceived satisfaction of other employees and improved standard of living) and job satisfaction were, as predicted, stronger for low SE whites than for high SE whites. Among blacks, however, the social reference variables were strongly related to job satisfaction regardless of level of SE. 相似文献

In Experiment I, six preschool-aged children were given matching-to-sample training with two figures in which they were required to choose one of two comparison stimuli that was identical in shape to the standard stimulus. Following this training, they were given intermittent test trials in which a novel stimulus figure was substituted for the previously correct comparison stimulus. Five of the six subjects consistently chose the substituted stimulus during test trials. Experiment II replicated the findings of Experiment I with three other preschool-aged children. Experiment II also provided controls for the possibility that the subjects of Experiment I were selecting the substituted stimulus because of its novelty. The investigators concluded that eight of the nine subjects were exhibiting the type of control described by Berryman, Cumming, Cohen, and Johnson (1965) as S-delta responding. 相似文献
