Background: Although the pattern of frontal electroencephalogram (EEG) asymmetry during the processing of emotion has been examined in many studies of healthy adults and typically developing infants and children, no published work has used these theoretical and methodological approaches to study emotion processing in children with Down syndrome.…

In this study, we investigated relations between infants' understanding of intentional actions and measures of social responsiveness during a transitional period, 9- to 11-months. Infants (N = 52) were tested in visual habituation paradigms tapping their understanding of the relation between a person and the object of her attention. Measures of…

This study examines a wide range of numerical representations (i.e., quantity, knowledge of multiplication facts, and use of parity information) in adult deaf signers. We introduce a modified version of the number bisection task, with sequential stimulus presentation, which allows for a systematic examination of mathematical skills in deaf…

A popular theoretical account of developmental language and literacy disorders implicates poor auditory temporal processing in their etiology, but evidence from studies using behavioral measures has yielded inconsistent results. The mismatch negativity (MMN) component of the auditory event-related potential has been recommended as an alternative,…

In this article, 41 models of covariation detection from 2 x 2 contingency tables were evaluated against past data in the literature and against data from new experiments. A new model was also included based on a limiting case of the normative phi-coefficient under an extreme rarity assumption, which has been shown to be an important factor in…

The conceptual basis for many effective language-training programs are based on Skinner's (1957) analysis of verbal behavior. Skinner described several elementary verbal operants including mands, tacts, intraverbals, and echoics. According to Skinner, responses that are the same topography may actually be functionally independent. Previous…

Students (N = 124) viewed 14 timed Web pages that distinguished 14 confusing word pairs. In a 2 x 2 factorial design, the authors gave all of the students matrices containing representational pictures for each pair of words, as well as examples of each word in use. One factor in the design was the absence or presence of rules of usage for each…

Assessment of auditory abilities is important in the diagnosis and treatment of children with autism. The aim was to evaluate hearing objectively by using transient evoked otoacoustic emission (TEOAE) and auditory brainstem response (ABR). Tests were performed on 30 children with autism and 15 typically developing children, following otomicroscopy…

Applying Bloch's law to visual word recognition research, both exposure duration of the prime and its luminance determine the prime's overall energy, and consequently determine the size of the priming effect. Nevertheless, experimenters using fast-priming paradigms traditionally focus only on the SOA between prime and target to reflect the…

Parkinson's disease (PD) patients and healthy controls were administered a flanker task that consisted of the presentation of colored targets and distractors. Participants were required to attend to the center target and identify its color. The stimulus displays were either congruent (i.e., the target and flankers were the same color) or…

In this exploratory case study we look at student media production to find out what students know and have learned about the media through production work. We used a media education conceptual framework developed by Dick as a means of describing the day to day media learning of a group of ten students, four girls and six boys, producing a video…

An analysis of French oral proficiency and guidelines for evaluating and testing the development of such proficiency in learning French as a second language are the keynotes of this dissertation. The speech patterns (structural complexity, rate of production, and hesitation) of three groups of French students with various levels of audiolingual…

This speech inventory used in a study of aurally handicapped children (see TM 001 129) measures lipreading ability. The 33-item inventory represents a meaningful sample of phonemes in Standard American English. This measure can be presented either live or by 16 millimeter film. See also TM 001 130, 131, and 133.

This monograph is a collection of papers describing a series of loosely related studies of visual attention, auditory stimulation, and language discrimination in young infants. Titles include: (1) Infant Attention and Discrimination: Methodological and Substantive Issues; (2) The Addition of Auditory Stimulation (Music) and an Interspersed…

We investigated the effects of transparent fraction names on children's reasoning about fractions. U.S. and Korean first and second graders were tested using verbal and nonverbal measures. On a verbal task, Korean students were worse at interpreting their own conventional fraction names than interpreting modified terms with a more familiar word…
