The author cites work on visual perception which indicates that in order to study perception it is necessary to replace such classical geometrical notions as betweeness, straightness, perpendicularity, and parallelism with more general concepts. The term tolerance geometry is used for any geometry when primitive notions are obtained from the…

Two studies assessed the kinesthetic aftereffect using a wide inducing block with the Petrie measurement procedure and a traditional procedure. The subjects included 76 male and 101 female undergraduates. Aftereffect scores were generally correlated as predicted. (TJH)

The relationship between the ability to perceive rhythm and the ability to read is discussed. (CK)

Analyzes a method of detecting changes in a particular frequency band by evaluating the overall shape or profile of the auditory signal spectrum. Claims that profile analysis is different from intensity discrimination, and applies the new method to detecting noise sinusoid and to results obtained when signal frequency is uncertain.

Purpose: To determine if listeners with normal hearing and listeners with sensorineural hearing loss give different perceptual weightings to cues for stop consonant place of articulation in noise versus reverberation listening conditions. Method: Nine listeners with normal hearing (23-28 years of age) and 10 listeners with sensorineural hearing…

Patients diagnosed with Autism Spectrum Disorder, show impaired integration of information across different senses. The processing-level from which this impairment originates, however, remains unclear. We investigated low-level integration of auditory and visual stimuli in subjects with Autism Spectrum Disorder. High-functioning adult subjects…

There is a crucial debate concerning the nature of chess chunks: One current possibility states that chunks are built by encoding particular combinations of pieces-on-squares (POSs), and that chunks are formed mostly by "close" pieces (in a "Euclidean" sense). A complementary hypothesis is that chunks are encoded by abstract,…

We previously reported a meta-analysis of explicit memory studies in populations with intellectual disability (ID). The current study discusses the educational implications of this meta-analysis. The main factors at the core of these implications can be divided into two categories: those related to task characteristics (e.g., depth of processing,…

An exploration of the effects of audiovisual communication modes upon the social environment. (CH)

The main purpose of this investigation was to study the relationships between visual memory and early reading achievement. Short term and intermediate memory were examined in relation to vocabulary, reading comprehension, and reading readiness in first grade pupils. The Gates MacGinitie Readiness Skills Test; the Visual Memory for Designs Tests,…

Thirty-six visual and auditory tests were given to 113 fifth and sixth grade students. Second-order analysis yielded two well-defined factors representing Fluid and Crystallized Intelligence and two perceptual factors corresponding to General Visualization and General Auditory Function. Perceptual factors were not clearly separated from broad…

The validity of the Kinesthetic Aftereffect (KAE) as a measure of personality has been criticized because of KAE's poor test-retest reliability. However, systematic bias effects render KA E retest sessions invalid and make test-retest reliability an inappropriate measure of KAE's true reliability. (Author/CTM)
