The effects of reinforcement and extinction on response variability and stimulus generalization in the punching and kicking techniques of 2 martial arts students were evaluated across drill and sparring conditions. During both conditions, the students were asked to demonstrate different techniques in response to an instructor's punching attack.…

The purpose of this sequential mixed methods study was to determine if students with autism from 19-to-26 years of age who receive instruction in Daily Living Skills (DLS) class sustain, improve, or decline in their ability to generalize DLS at home and in the community. Research regarding how well students with autism from 19-to-26 years of age…

In this paper, I consider one mechanism by which racial categories, racial "common sense," and thus the social organization of race itself, are reproduced in interaction. I approach these issues by using an ethnomethodological, conversation analytic approach to analyze a range of practices employed by participants of a "race-training" workshop.…

Tasks regularly completed by elementary teachers reveal the mathematical nature of their work. However, preservice teachers demonstrate a lack of depth of mathematical thought. This study investigated the criteria preservice teachers intuitively used to evaluate algorithms. The intent was to use that knowledge as a foundation for modeling…

Background: There is considerable evidence suggesting that many children show conduct problems that are specific to a given context (home; school). What is less well understood is the extent to which children with situation-specific conduct problems show similar outcomes to those with generalised conduct problems. Methods: Data were gathered as…

The quality of the relationships that mentors forge with their proteges is assumed to significantly affect the success of mentoring interventions. Building on previous research, this study examined the association between relationship qualities and protege functioning. Multiple reporters (e.g., mentors, proteges and teachers) were used in a…

This paper describes the nature of stimulus and response generalization and identifies a number of tasks related to generalization that are commonly taught in early childhood programs. Substantial research has demonstrated that stimulus generalization does not occur automatically and it can often be achieved only as a result of special programing.…

The effect of syntax training on the sentence production of four adults with Broca's aphasia was examined. Generalization and maintenance were measured, and naive judges rated "adequacy" of responses. Findings indicated that effects are limited to the grammatical constructions taught, and that effects on response adequacy may be limited.…

REL Southwest received a request to review the report "Avoidable Losses: High Stakes Accountability and the Dropout Crisis" to assess the soundness of the study methodology and the appropriateness of the conclusions drawn in the report. The review found that conclusions drawn in this study cannot be generalized and are significantly…

Research supports the difficulties that students with Asperger's Syndrome (AS) and High-Functioning Autism (HFA) have in developing successful interpersonal relationships. While they want to establish friendships, students with AS fail to recognize and accurately interpret social cues and verbal and nonverbal behavior (Iovannone, Dunlap, Huber, &…

Neural changes related to learning of the meaning of Chinese characters in English speakers were examined using functional magnetic resonance imaging (fMRI). We examined item specific learning effects for trained characters, but also the generalization of semantic knowledge to novel transfer characters that shared a semantic radical (part of a…

Person-fit methods are used to uncover atypical test performance as reflected in the pattern of scores on individual items in a test. Unlike parametric person-fit statistics, nonparametric person-fit statistics do not require fitting a parametric test theory model. This study investigates the effectiveness of generalizations of nonparametric…

Using the telephone to contact others can be an important skill in maintaining friendships with peers. This investigation used a system of least prompts (SLP) procedures to teach two telephone skills to 3 elementary students with cognitive disabilities: (a) placing phone calls and (b) leaving recorded voicemail messages. The SLP procedure was…

Recent research examining racial differences on standardized cognitive tests has focused on the impact of test item difficulty. Studies using data from the SAT and GRE have reported a correlation between item difficulty and differential item functioning (DIF) such that minority test takers are less likely than majority test takers to respond…

This study examined the effects of training and feedback on instructor performance of Discrete Trial Teaching (DTT) and support skills. This included an examination of the generalization and maintenance of instructor skills, and the impact of instructor skills on student performance. Six undergraduate research assistants received an 8-hour…
