The effects of programming common stimuli for enhancing stimulus generalization of academic behavior
Programming common stimuli is a strategy for generalizing behavior across settings (Stokes & Baer, 1977). The present study programmed common stimuli (i.e., goal statement and use of a pictorial icon) to generalize the effects of a reinforcement-based intervention for students identified as either developmentally delayed or emotionally disturbed. Results supported the effectiveness of the strategy in producing generalized responding from training to the generalization setting. The importance of methodological rigor in future research exploring generalization and the need to compare generalization strategies are discussed. 相似文献

Attitude generalization was explored as a function of object similarity and attitude valence and extremity. Participants in a computer game formed attitudes toward positive and negative, mild or extreme stimuli. How well these attitudes generalized to similar, novel stimuli was then examined. Visual similarity to game targets affected categorization of novel stimuli, such that greater resemblance resulted in more similar classification. However, generalization varied by valence and extremity. Negative attitudes generalized more than positive attitudes, requiring less resemblance for a novel target to be classified as negative. This pattern was more obvious with extreme attitudes than mild attitudes. That is, extreme attitudes were more influential and given more weight than mild attitudes. Also, specific conditions were identified under which positive attitudes proved more influential than negative attitudes. 相似文献

Four pigeons were first trained in a timing procedure. In one condition, each trial began with the presentation of an X on the center key, followed by a delay (short or long), after which two side keys were lit. If the delay was short, pecks to the red side key were reinforced. If the delay was long, pecks to the green side key were reinforced. In a second condition, the opposite contingencies applied following presentation of a square on the center key. Choice responses were then tested at 10 time intervals ranging from short to long (1 to 4 s and 4 to 7 s in different conditions). The two timing conditions were combined to create a remembering condition in which correct responding depended upon discrimination of both the sample stimulus (X or square) and the delay interval (short or long). Choices varied systematically across delay in timing conditions, but in remembering conditions, accurate choice at the training delays did not initially generalize to intermediate delays. However, with prolonged training in the remembering task, the response pattern began to resemble that of the timing conditions. Generalization gradients were asymmetrical, in accordance with Weber's Law, in that greater generalization occurred with longer delays than with shorter delays. 相似文献

Although the literature clearly demonstrates that repeated readings result in immediate effects on students' performance on the intervention materials as well as long‐term benefits, data are less promising regarding its immediate generalization effects to similar materials. Using an alternating treatments design, the current study evaluated the effects of a multicomponent repeated reading intervention on generalization passages after students had read a passage three versus six times. Results indicated improvements in fluency as a result of both interventions, with slightly greater maintenance effects when students were given six opportunities to read passages. 相似文献

Individuals diagnosed with autism spectrum disorder (ASD) often respond poorly to novel stimulus combinations and may have difficulty discriminating across critical and noncritical stimulus dimensions without direct teaching. General‐case procedures and multiple‐exemplar training have been effectively used to address this deficit. In the current study, the experimenters outlined general‐case procedures with video modeling, prompting and reinforcement to teach three adolescents with ASD a generalized repertoire of using a chip‐debit card. A multiple‐probe across participants design demonstrated the effectiveness of these procedures. All participants acquired the skill, responding generalized from simulated teaching materials to four novel automatic payment machines, and maintained 4 weeks following teaching. Implications of using these general‐case procedures as a blueprint for future researchers to reference when teaching individuals with ASD a generalized repertoire of any skill are discussed. 相似文献

The current study examines the effect of parent reading interventions on the reading fluency of students with reading disabilities. The experimental procedure was carried out in two stages. In the first stage, the Brief Experimental Analysis procedure was followed to determine the most effective reading fluency intervention for all participants, and in the next step, the parental delivery of the selected intervention procedure took place. Brief experimental analysis was used to identify appropriate reading fluency intervention for each participant. Parents were trained to use the intervention strategies with their children. They implemented the procedures during parent‐tutoring sessions at home and results were measured continuously to determine whether generalization occurred. Parent and child satisfaction with the interventions was assessed. Results demonstrated generalized increases in reading fluency in both high‐word‐overlap and low‐word‐overlap passages as a function of parent tutoring. Also, acceptability ratings by children and their parents indicated that they viewed the interventions as acceptable and effective. 相似文献

Verbal mediating responses: effects on generalization of say-do correspondence and noncorrespondence
We analyzed the effects of verbal mediating responses on the acquisition and generalization of say-do correspondence and noncorrespondence. Participants were assigned to groups in which either reinforcers (feedback and tokens) were arranged for say-do correspondence and noncorrespondence, or no reinforcers were programmed. Participants in these groups were further subdivided into groups in which they were required to repeat what was said previously, were required to repeat random numbers, or no verbalizations were required. When correspondence was reinforced, repetition of what was said produced greater acquisition and generalization of correspondence. When noncorrespondence was reinforced, repetition of numbers facilitated acquisition and generalization of noncorrespondence. Verbal mediating responses interacted with contingencies of reinforcement in determining acquisition and generalization of correspondence and noncorrespondence. 相似文献

Preference assessments directly evaluate items that may serve as reinforcers, and their implementation is an important skill for individuals who work with children. This study examined the effectiveness of pyramidal training on teachers' implementation of preference assessments. During Experiment 1, 3 special education teachers taught 6 trainees to conduct paired-choice, multiple-stimulus without replacement, and free-operant preference assessments. All trainees acquired skills necessary to implement preference assessments with 90% or greater accuracy during the training sessions and demonstrated generalization of skills to their classrooms or clinic. During Experiment 2, 5 teachers who served as trainees in Experiment 1 trained 18 preschool teachers. All preschool teachers met the mastery criterion following training. Training teachers to implement preference assessments may increase teachers' acceptance and use of behavior-analytic procedures in school settings. 相似文献

A modified incidental-teaching procedure was used to increase the receptive language skills of autistic youth who had previously experienced lengthy institutionalization. At the time of the study, the two severely language-delayed children had recently been transitioned to a community-based group home. Receptive-labeling skills were taught for four sets of objects typically used in school lunch preparation. The percentage of correct, unprompted object identifications displayed by Youth 1 increased when the incidental-teaching package (gestural prompts, behavior-specific praise, and contingent access to lunch-making supplies) was sequentially introduced in a multiple-baseline design across sets of objects. These results were replicated with Youth 2. The youths' newly acquired language skills also generalized to a different setting (the dining room of the group home) and to a different activity occurring later in the day (a traditional sit-down, discrete-trial session). This research indicates that the linguistic skills of severely developmentally delayed autistic children can be accelerated by incidental instruction that is provided in the course of shaping other home-living skills. 相似文献
