More than 30 years later, the present study evaluated whether spatial ability provided incremental validity (beyond the SAT’s mathematical and verbal reasoning subtests) for differentially predicting which of these individuals had patents and three classes of refereed publications. A two-step discriminant-function analysis revealed that the SAT subtests jointly accounted for 10.8% of the variance among these outcomes ( p < .01); when spatial ability was added, an additional 7.6% was accounted for—a statistically significant increase ( p < .01). The findings indicate that spatial ability has a unique role in the development of creativity, beyond the roles played by the abilities traditionally measured in educational selection, counseling, and industrial-organizational psychology. Spatial ability plays a key and unique role in struct...

Four types of lateral preference (handedness, footedness, eyedness, and earedness) were measured in a sample of 962 individuals, ranging in age from 10 to 75 years. Factor analytic techniques were used to assess whether these aspects of laterality are manifestations of a common process or whether they should be viewed as a multidimensional complex. Three independent factors, representing limb, eye and ear preference were obtained. This dimensional structure remained invariant across the separate sex and age subgroups within the sample. These results suggest that human laterality is a multidimensional process, and that laterality of limbs and sense organs may result from different mechanisms.

The methods are implemented in a freeware Mathematica package, WBCORR, and illustrated with numerical examples, including comparison of correlation matrices over time, simultaneous comparison of sets of correlations in two or more independent groups, comparison of several predictors of the same criterion, comparison of circumplex structures across groups, and comparison of predictor-criterion relations across groups. Comparing Correlations Page 3 Comparing Correlations: Pattern Hypothesis Tests Between and/or Within Independent Samples Preamble Many years ago, a psychologist colleague approached me with a question about how to compare two dependent correlations. He was puzzled because equations in two of the few papers then available on the topic seemed to disagree (actually, both contained minor typographical ...

In the quarter century that followed, Meehl's views stimulated much debate and progress, while continually evolving to keep pace with that progress. This paper pays homage to Meehl's prescience, and traces the impact of his ideas on the recent shift of emphasis away from hypothesis testing and toward confidence interval estimates of effect size.

Two related findings emerged: (a) a substantial reduction in RT slope in a &amp;amp;amp;quot;memory&amp;amp;amp;quot; version of the &amp;amp;amp;quot;mental rotation&amp;amp;amp;quot; paradigm and (b) evidence from &amp;amp;amp;quot;fold point&amp;amp;amp;quot; analyses to suggest individualized strategies by Ss

(4) We call any vector x E RN a "vector of deviation scores" if it is in the null space of 1', so that: In general, Sp(V,) is not uniquely defined by Sp(V), Sp(VI) in Equation 3. If one defines Sp(V,) as an "orthogonal complement of Sp(V.)" [relative to Sp(V)] and writes iff VI ESp(V I), v, ESp(V,)-vl'v, =0, then Sp(V,) is uniquely defined in terms of Sp(V) and Sp(VI)' as is well known. We therefore could define Sp simply as the orthogonal complement ofSp(J) in RN: (5) (3) (2) (1) (6) J'x =0, Sp(V.) 1 Sp(V,) J' =(I, I, ... , 1). THE FACTOR MODEL Sp(V) =Sp(VI) <IISp(V,) RN =Sp <II Sp(J), Sp 1 Sp(J) iff v E Sp(V) => v =VI + v,. with VI E Sp(V I) , v, E Sp(V,), and for a given V, VI' V" and v, the vectors VI and v, are uniquely defined. We call Sp(V) the direct sum of Sp(Vk), k =1,2. It is well known that in this case the dimensions add, that is, its sample mean is x =~XfjN =J'xjN =0. As is well known, this null space (i.e., the! space of all deviation score vectors for fixed sample size N) has dimension N-1. We denote this space "Sp" and write Sp C RN to indicate that it is a proper subspace of RN.
