This study empirically evaluated a classification schema based on symbolic communication level use with students with significant cognitive disabilities. Ninety-five teachers of students with significant disabilities rated students' level of performance on 10 academic tasks. Cluster analysis suggested a range of two to four clusters solutions.…

A critical issue in perception is the manner in which top-down expectancies guide lower level perceptual processes. In speech, a common paradigm is to construct continua ranging between two phonetic endpoints and to determine how higher level lexical context influences the perceived boundary. We applied this approach to music, presenting…

Three experiments were aimed at verifying whether the modality of interaction with objects and the goals defined by the task influences the weight of the properties used for categorization. In Experiment 1 we used everyday objects (cups and glasses). In order to exclude that the results depended on pre-stored categorical knowledge and to assess…

The goal of the current study was to examine whether explaining to another person improves learning and transfer. In the study, 4- and 5-year-olds (N=54) solved multiple classification problems, received accuracy feedback, and were prompted to explain the correct solutions to their moms, to explain the correct solutions to themselves, or to repeat…

This paper reviews the literature regarding the treatment of phobic avoidance in individuals with intellectual disabilities. Criteria for classifying interventions as empirically supported, developed by the American Psychological Association (APA) Division 12 Task Force on Promotion and Dissemination of Psychological Procedures, were used. For…

The processes of overall similarity sorting were investigated in 5 free classification experiments. Experiments 1 and 2 demonstrated that increasing time pressure can reduce the likelihood of overall similarity categorization. Experiment 3 showed that a concurrent load also reduced overall similarity sorting. These findings suggest that overall…

The Gross Motor Function Classification System (GMFCS) for cerebral palsy has been widely used internationally for clinical, research, and administrative purposes. This paper recounts the ideas and work behind the creation of the GMFCS, reports on the lessons learned, and identifies some philosophical challenges inherent in trying to develop an…

Decades of research have documented in school-aged children a persistent difficulty apprehending an overarching biological concept that encompasses animate entities such as humans and nonhuman animals, as well as plants. This has led many researchers to conclude that young children have yet to integrate plants and animate entities into a concept…

This paper examines ways in which language planning has been used to address issues of security. It gives an overview of a range of areas of security in which government-level language planning has had a role as a way of developing a typology of language planning work in this area. It examines the nexus between language, communication and security…

Given the increasing rates of autism, identifying prompting procedures that can assist in the development of more optimal learning opportunities for this population is critical. Extensive empirical research exists supporting the effectiveness of various prompting strategies. Constant time delay (CTD) is a highly implemented prompting procedure…

In this study hemispheric asymmetries for categorizing objects at the basic versus subordinate level of abstraction were investigated. As predictions derived from different theoretical approaches are contradictory and experimental evidence is inconclusive in this regard, we conducted two categorization experiments, where we contrasted two…

Background: It has long been appreciated that people with intellectual disabilities experience mental health problems. Studies into the prevalence of personality disorder in the population of people with an intellectual disability indicate significant variations, which have no clear explanation. Method: Work on personality disorder and personality…

School choice is one of the most frequent recommendations for education reform in the United States today. Unfortunately, the debates are hindered by the lack of a common taxonomy or framework for discussing and evaluating the wide variety of school choice programs available in the United States. Furthermore, there is little information on the…

This article describes a creative intervention used in an independent study course which focused on Enneagram studies. In addition to extensive reading, writing, discussion, and reflection at weekly meetings, one assignment for the course involved the compilation of songs that depict the core motivations, fears, and desires for each type.…
