Object-substitution masking (OSM) occurs when a mask, such as four dots that surround a brief target item, onsets simultaneously with the target and offsets a short time after the target, rather than simultaneously with it. OSM is a reduction in accuracy of reporting the target with the temporally trailing mask, compared with the simultaneously…

This study is designed to test the hypothesis that an inability to separate incoming information into discrete messages is a source of young children's relatively poor performance in selective attention tasks. Subjects were 27 children drawn from kindergarten, second grade and fifth grade classes. (Author/GO)

The attention hypothesis of Zeaman and House is examined through a systematic, computer-simulation analysis of the parameter interactions found in One-Look model. (Author/SB)

Investigates the dominance of global versus local visual properties in four-month-old infants as a function of individual differences in fixation duration. Suggests that long-looking infants process visual information more slowly than short-looking infants, and there may be qualitative differences in the manner in which the two groups of infants…

Overselective attention in discrimination between picture cards was investigated with three groups of children with different IQ levels: 10 severely retarded (IQ = 29 - 51, CA = 9.6 - 18 years), 10 moderately retarded (IQ = 56 - 85, CA = 12.8 - 16.3 years), and 10 non-retarded (CA = 10 - 12 years).

Examines the relationship of grade level to children's ability to make musical discriminations when elements are presented simultaneously. Utilized a brief instructional period, listening tests, and singing tasks. Results indicated significant differences between grade level, types of discrimination, and musical interactions. Includes statistical…

Examines the relationship between vocal pitch accuracy and gender, grade level, and the presence or absence of an accompanying unison voice. Reveals no significant differences between unison or individual singing or for gender. Fourth and fifth graders exhibited significant differences. (MJP)
