The effects of vocal intraverbal training and listener training on the emergence of untrained categorization skills were evaluated. Five typically developing preschool children initially learned to name a number of previously unfamiliar visual stimuli. Each child then received one of two types of training. Intraverbal training involved reinforcing…

In this study we demonstrate that Korean (but not English) speakers show Categorical perception (CP) on a visual search task for a boundary between two Korean colour categories that is not marked in English. These effects were observed regardless of whether target items were presented to the left or right visual field. Because this boundary is…

Although historians of psychological and educational sciences have not completely neglected early research in the field of morality testing, European contributions to the measurement of ethical judgement and moral feeling have not received much historical attention. In this paper, two principal, experimental paradigms that emerged in early…

People will often look to empty, uninformative locations in the world when trying to recall spoken information. This spatial indexing behaviour occurs when the information had previously been associated with those locations. It remains unclear, however, whether this behaviour is an example of a simple association across perceptual and cognitive…

Lissitz and Samuelsen (2007) have proposed an operational definition of "validity" that shifts many of the questions traditionally considered under validity to a separate category associated with the utility of test use. Operational definitions support inferences about how well people perform some kind of task or how they respond to some kind of…

This research investigated how fourth and fifth grade students spontaneously "unpacked" a word problem when generating a graphic representation to aid in problem solution. Relationships among the type of graphic representation produced, spatial visualization, drawing ability, gender, and problem solving also were examined and described.…

Over the past few decades, the reported number of children identified as having one of the Autism Spectrum Disorders (ASD) has increased exponentially. One proposed reason for the dramatic increase in the prevalence of ASD is diagnostic substitution, whereby children with other disorders incorrectly receive a diagnosis of ASD. Little research has…

The autism spectrum disorders (ASD) have generated great interest among clinicians and researchers. Once considered rare, recent epidemiological data now suggests rates of up to 1 in 150 people. One of the most frequent of the ASD, Asperger's syndrome (AS), has been known as a disorder for as long as autism, which is easily the most visible of…

The majority of work on the double-deficit hypothesis (DDH) of dyslexia has been done at the letter and word levels of reading. Key research questions addressed in this study are (a) do readers with different subtypes of dyslexia display differences in fluency at particular reading levels (e.g., letter, word, and connected text)? and (b) do…

Three classification techniques (Chi-square Automatic Interaction Detection [CHAID], Classification and Regression Tree [CART], and discriminant analysis) were tested to determine their accuracy in predicting Temporary Assistance for Needy Families program recipients' future employment. Technique evaluation was based on proportion of correctly…

This article reports on a comparison of lexical items in the vocabulary of Icelandic and Danish sign languages prompted by anecdotal reports of similarity and historical records detailing close contact between the two communities. Drawing on previous studies, including Bickford (2005), McKee and Kennedy (1998, 2000a, 2000b) and Parkhurst and…

This literature review of existing electronic mobility aids for persons who are visually impaired and recent developments in this field identified and classified 146 products, systems, and devices. The 21 that are currently available that can be used without environmental adaptation are described in functional terms. (Contains 2 tables.)

Tremendous growth in educational technology tools, applications, and Web 2.0 resources have created a plethora of new methods to meet the learning needs of all students. Unfortunately, the potential of these methods is hardly understood before a new technological breakthrough makes its way into the classroom, through either teachers or, more…

Subscribing to Systemic Functional Linguistics approach, this paper examines aspects of decontextualised language, such as classification and definitions, in Greek pre-school instructional contexts. Following the assumption that such decontextualised uses are considered critical to the transition from commonsense to educational knowledge, we…

This article seeks to expand our understanding of narrative and the analysis of stories researchers invite and collect in the domain of disability studies. What narrative inquiry is and various reasons why researchers might opt to choose to turn to narratives are highlighted. Painting with broad strokes, narrative analysis is then considered…
