We review the GIDNA and CDM packages in R for fitting cognitive diagnosis/diagnostic classification models. We first provide a summary of their core capabilities and then use both simulated and real data to compare their functionalities in practice. We found that the most relevant routines in the two packages appear to be more similar than…

Converging evidence from behavioral masked priming (Rastle & Davis, 2008), EEG masked priming (Morris, Frank, Grainger, & Holcomb, 2007) and single word MEG (Zweig & Pylkkanen, 2008) experiments has provided robust support for a model of lexical processing which includes an early, automatic, visual word form based stage of morphological parsing…

This study examined irrelevant/incorrect answers produced by children with Asperger syndrome or high-functioning autism (7-9-year-olds and 10-12-year-olds) and normally developing children (7-9-year-olds). The errors produced were divided into three types: in Type 1, the child answered the original question incorrectly, in Type 2, the child gave a…

Deficits in theory of mind (ToM), evident in most individuals with autism, have been suggested as a core deficit of autism. ToM difficulties in young siblings of children with autism (SIBS-A) compared to siblings of typically developing children (SIBS-TD) would place the former within the broad phenotype. We examined ToM's possible associations…

A sequential-touching task was used to investigate whether 14-month-old infants can rapidly change how they categorize a set of objects, recognizing new groupings of objects they had previously categorized in a different way. When presented with a collection of objects that could be categorized by shape (balls vs. blocks) or material (soft vs.…

This paper examines and critiques several learning style inventories (LSI) in an effort to find the optimal research instrument for a proposed empirical study of both the quality of courseware and the impact of courseware characteristics on variations of learning effectiveness due to learner characteristics. Five LSIs are examined: (1) Dunn LSI;…

An experiment to determine if different affective responses would result from exposure to three different forms of media presenting the same content used a semantic differential to measure affective response, and an objective test to measure cognitive learning. Analysis of covariance indicated significantly less learning for audiotaped version of…

A significant amount of research treats students who speak a language other than English at home, or language-minority students, as a single demographic group and compares them to students who speak only English at home. If important disparities in early school experiences among language-minority students have been overlooked, then policies aimed…

Concern about the possible bias of using only verbal assessments for the identification of intellectually gifted students led to an examination of the effect of incorporating nonverbal assessments of intelligence into the identification process. Two nonverbal instruments (Progressive Matrices and Test of Nonverbal Intelligence) were used in…

Theoretical framework, instrument development, and psychometric qualities are reviewed for some measures of learning style currently in use with adults. Instruments reviewed include: (1) Kolb's Learning Style Inventory I; (2) Kolb's Learning Style Inventory II; (3) the Myers-Briggs Type Indicator; (4) the Productivity Environmental Preferences…

Offers a report on Visions for Children--an early childhood demonstration program with the goal of facilitating intellectual development and academic achievement and enhancing self-concepts of African-American preschoolers. Base-line data from the first two phases of child testing comparing program participants and control group children is…
