Peer reviewed Peer reviewed
Direct linkDirect link
Gifford, Rene H.; Bacon, Sid P.; Williams, Erica J. – Journal of Speech, Language, and Hearing Research, 2007
Purpose: To compare speech intelligibility in the presence of a 10-Hz square-wave noise masker in younger and older listeners and to relate performance to recovery from forward masking. Method: The signal-to-noise ratio required to achieve 50% sentence identification in the presence of a 10-Hz square-wave noise masker was obtained for each of the…

Visual Retention Test: An Analysis of Children's Errors.
Rice, James A., Bobele, R. Monte
Grade level norms were developed, based on a sample of 678 elementary school students, for various error scores of the Benton Visual Retention Test. Norms were also developed for 201 normal children, 58 minimal brain dysfunction children, and 101 educable mentally retarded children. In both the copying mode and the memory mode, most errors were…

Zullo, Thomas G. – 1971
A battery of perceptual motor skills tests was administered to 107 freshman and 84 senior dental students for the purposes of determining the factor structure of the battery and studying differences between the two groups. The tests used included Minnesota Rate of Manipulation Test (MRM), Placing and Turning; O'Connor Finger Dexterity; O'Connor…

Perceptual Sensitivity to Dimensional and Similarity Relations in Free and Rule-Governed Classifications.
Peer reviewed Peer reviewed
Cook, Gregory L.; Odom, Richard D. – Journal of Experimental Child Psychology, 1988
Two experiments investigated perceptual primacy of dimensional and similarity relations in stimulus classifications of younger and older subjects. Results support a differential-sensitivity view of perceptual development which asserts that individuals at all ages primarily perceive and use separate relations. (RWB)

Stability and Change in Broad and Narrow Factors of Intelligence from Ages 12 to 15 Years.
Peer reviewed Peer reviewed
Gustafsson, Jan-Eric; Undheim, Johan Olav – Journal of Educational Psychology, 1992
The stability of some dimensions of ability between the ages of 12 and 15 years was investigated for 225 boys and 242 girls in Sweden. Testing in grades 6, 8, and 9 indicated high stability for the general intelligence factor and for the residual of the General Visual factor. (SLD)

Response Modality Variations Affect Determinations of Children's Learning Styles.
PDF on ERIC Download full text
Janowitz, Jeffrey M. – 1992
The Swassing-Barbe Modality Index (SBMI) uses visual, auditory, and tactile inputs, but only reconstructed output, to measure children's modality strengths. In this experiment, the SBMI's three input modalities were crossed with two output modalities (spoken and drawn) in addition to the reconstructed standard to result in nine treatment…
