The purpose of this study was to determine whether cognitive-process approach based social skills program was effective on learning and generalizing three social skills (apologizing, coping with teasing and avoiding inappropriate touching) of the nine students with mental retardation. Social skills program covered dimensions of the cognitive…

Human infants possess powerful learning mechanisms used for the acquisition of language. To what extent are these mechanisms domain specific? One well-known infant language learning mechanism is the ability to detect and generalize rule-like similarity patterns, such as ABA or ABB [Marcus, G. F., Vijayan, S., Rao, S. B., & Vishton, P. M. (1999).…

The authors develop and test generalized versions of take-the-best (TTB) and rational (RAT) models of multiattribute paired-comparison inference. The generalized models make allowances for subjective attribute weighting, probabilistic orders of attribute inspection, and noisy decision making. A key new test involves a response-time (RT)…

The Picture Exchange Communication System (PECS) is an augmentative and alternative communication program (Frost & Bondy, 2002). Although PECS has been effectively used to teach functional requesting skills for children with autism, mental retardation, visual impairment, and physical disabilities (e.g., Anderson, Moore, & Bourne, 2007; Chambers &…

The NCTM calls for the use of rich tasks that encourage students to apply their own reasoning to problem situations. When students work through algebraic generalization tasks, their reasoning often elicits a variety of strategies (Lannin 2003; Stacey 1989; Swafford and Langrall 2000). Challenges for teachers include facilitating student awareness…

Purpose: Semantic feature analysis (SFA) was used to determine whether training contextually related words would improve the discourse of individuals with nonfluent aphasia in preselected contexts. Method: A modified multiple-probes-across-behaviors design was used to train target words using SFA in 3 adults with nonfluent aphasia. Pretreatment,…

This article shows that measurement invariance (defined in terms of an invariant measurement model in different groups) is generally inconsistent with selection invariance (defined in terms of equal sensitivity and specificity across groups). In particular, when a unidimensional measurement instrument is used and group differences are present in…

The generalization effects of empirically-supported fluency-based reading interventions have been largely ignored. The purpose of this study was to evaluate the effects of two fluency-based reading interventions, Repeated Readings and Multiple Exemplars, on elementary-aged children's immediate and generalized oral reading fluency rate. Using a…

Outcomes of three different types of computerized training in sub-lexical items (word-initial consonant clusters) on reading speed for 39 German-speaking poor readers in Grades 2 and 3 were evaluated. A phonological-orthographic association group, a reading aloud group, and a combined group were compared in performance with an untrained control…

For more than 20 years, the Ways of Coping Scale (WOCS) has been used extensively to measure coping. Yet beyond the original psychometric data, few studies have reexamined its properties utilizing the enormous body of research generated on the WOCS. Reliability has been assumed to be consistent as an attribute of the test. This study used…

People are capable of thinking about the future, the past, remote locations, another person's perspective, and counterfactual alternatives. Without denying the uniqueness of each process, it is proposed that they constitute different forms of traversing psychological distance. Psychological distance is egocentric: Its reference point is the self…

The conditions under which symmetry and equivalence relations develop are still controversial. This paper reports three experiments that attempt to analyze the impact of multiple-exemplar training (MET) in receptive symmetry on the emergence of visual-visual equivalence relations with a very young child, Gloria. At the age of 15 months 24 days…

This study investigated conditions leading to contextual control by stimulus topography over transfer of functions. Three 4-member stimulus equivalence classes, each consisting of four (A, B, C, D) topographically distinct visual stimuli, were established for 5 college students. Across classes, designated A stimuli were open-ended linear figures,…

In three experiments, match-to-sample procedures were used with undergraduates to establish arbitrary relational functions for three abstract visual stimuli. In the presence of samples A, B, and C, participants were trained to select the smallest, middle, and largest member, respectively, of a series of three-comparison arrays. In Experiment 1,…

The current study describes the assessment and treatment of the problem behavior of 3 individuals with autism for whom initial functional analysis results were inconclusive. Subsequent analyses revealed that the interruption of free-operant behavior using "do" requests (Study 1) as well as "do" and "don't" requests (Study 2) occasioned problem…
