The Snijders-Oomen Nonverbal Intelligence Test (SON) was administered to 251 deaf children (6-15 years old) and 101 hearing children (10-12 years old) in Israel. The SON was judged appropriate for measuring cognitive functioning in the deaf because it requires no verbal instructions or responses and includes a measure of abstract thinking ability.…

A "doubly-centered" raw data matrix is one for which both columns and rows have both unit variance and means equal to zero. The factor scores from one analysis are the same as factor pattern coefficients from the other analysis except for a variance adjustment. This study explored an extension of the reciprocity principle which may have…

This study attempted to clarify the structure of mathematical abilities through reanalysis of 48 factor-analytic studies. The factors were compared in six families: General, Numerical, Reasoning, Spatial, Verbal, and Mathematical. Eleven data sets were reanalyzed, with principal factor analysis followed by graphical rotation to oblique, simple…

Using the personality trait versus state distinction as a substantive context, the fit of the factor analytic model to difference score data is investigated and found to be quite good. Methodological issues related to properties of difference scores and their implications for personality research are briefly discussed. (Author)

Second order personality factors (those that do not appear in children) were investigated in male and female high school students. Two forms of the high School Personality Questionnaire were used as the basis of the study. (DP)

A factor analytic study was designed to examine the factor structure of a battery of 17 tests administered to 100 students at the primary, intermediate, and advanced (grades 7-10) levels and to determine differences in factor structures for the three groups. The tests, measures of academic achievement, included the Wechsler Intelligence Scale for…

The objectives of this research were to utilize factor analysis to explore the validity and reliability of the Litwin and Stringer Organization Climate instrument. (Author)

In this study, 16 strength, work, and power tests were administered to 50 male college students, and scores were analyzed using multiple factor analytic models. (JS)

A method is proposed for the evaluation of the degree to which trait measures show stability across diverse methods of measurement. The technique is illustrated using multitrait-multimethod matrices from personality assessment, which yield trait-specific factors. (Author/BJG)

The procedures involve a planned data gathering strategy consisting of at least two different groups, each receiving two different test batteries. A combination of Tucker's interbattery technique and congruence measures was the recommended strategy. Limitations of the concept of factor invariance are briefly discussed. (Author/BJG)

Examined two assumptions about the dimensionality of Rotters' Internal-External (I-E) scale: First, the bipolarity of the two statements within each item pair; second, the unidimensionality of the overall construct. Both assumptions regarding Rotters' I-E Scale were found untenable. (Author/BJG)
