This issue of "FOCUS" discusses external validity and what rehabilitation researchers can do to help practitioners answer the question "How far can we generalize this finding-- is it applicable to other clients/patients, with different characteristics, in dissimilar settings treated by other clinicians?," which clinicians and…

As bilingualism becomes less exceptional in the world, and with the growing incidence of stroke and aphasia, a better understanding of how bilingualism affects aphasia recovery is increasingly important. The present study examined the effect of intensive semantic naming therapy in three phases (Spanish, English and mixed) on within- and…

We explored whether the generalization of rules based on simple structures depends on attention. Participants were exposed to a stream of artificial words that followed a simple syllabic structure (ABA or AAB), overlaid on a sequence of familiar noises. After passively listening, participants successfully recognized the individual words present in…

A case study design was used to evaluate the effectiveness of behavioural consultation as a method for improving the social skills of adolescents with Asperger's syndrome. Two case studies were conducted. In each study, two teachers implemented a social skills programme with two to three adolescents with Asperger's syndrome in a group setting with…

The Problem-Solving Inventory (PSI; Heppner & Petersen, 1982) was developed to assess perceived problem-solving abilities. Using confirmatory factor analysis, results supported a bilevel model of PSI scores with a sample of 164 Mexican American students. Findings support the cultural validity of PSI scores with Mexican Americans and enhance the…

To better understand short-term memory for temporal intervals, we re-examined the choose-short effect. In Experiment 1, to contrast the predictions of two models of this effect, the subjective shortening and the coding models, pigeons were exposed to a delayed matching-to-sample task with three sample durations (2, 6 and 18 s) and retention…

Prior research suggests that preschoolers can generalize object properties based on category information conveyed by semantically-similar labels. However, previous research did not control for co-occurrence probability of labels in natural speech. The current studies re-assessed children's generalization with semantically-similar labels.…

The Picture Exchange Communication System (PECS) is an augmentative and alternative communication (AAC) program used to teach functional requesting and commenting skills to people with disabilities (Bondy & Frost, 1993; Frost & Bondy, 2002). In this study, tangible symbols were added to PECS in teaching requesting to four students (ages 7-14) with…

Individuals with autism spectrum disorders (ASD) often exhibit impaired executive function (EF) performance, including difficulty with working memory (WM), in particular. While research has documented the existence of these deficits, surprisingly little research exists that evaluates potential treatment strategies for improving EF or WM. One…

The purpose of this study was to employ the meta-analytic method of Reliability Generalization to investigate the magnitude and variability of reliability estimates obtained across studies using Curriculum-Based Measurement reading aloud. Twenty-eight studies that met the inclusion criteria were used to calculate the overall mean reliability of…

In this study, 2.5-, 3-, and 4-year-olds (N=108) participated in a novel noun generalization task in which background context was manipulated. During the learning phase of each trial, children were presented with exemplars in one or multiple background contexts. At the test, children were asked to generalize to a novel exemplar in either the same…

Purpose: The purpose of this research was to identify factors that influence the use of project management in higher education research projects by investigating the project management practices of assistant professors. Design/methodology/approach: Using a grounded theory approach that included in-depth, semi-structured interviews with 22…

Validating and generalizing from holistic observation protocols of classroom practice have proven difficult. These tools miss crucial classroom characteristics, like the type of instruction, the organization of learners, and the level of cognitive engagement that occur differentially in the time span of a lesson. As a result, this study examined…

Issues emerging from instructional innovation are inevitable, yet basing any curriculum shift on a theoretical framework is paramount. This paper grounds the case-based pedagogy in three learning theories: behaviorism, cognitivism, and constructivism. The three theories are described and situated in relation to the case study method. An…

International competition drives research universities to find ways to anchor globalization for academic productivity and innovation through cross-border collaboration. This article examines the case of pre- and post-colonial Hong Kong and how its universities transited from undergraduate institutions to highly ranked research universities within…
