This study investigated the structure and development of processes involved in "g." One hundred and forty children, about equally drawn among primary school grades 1-6 were examined by four types of Stroop-like speeded tasks addressed to processes of increasing complexity (i.e., speed of processing, perceptual discrimination, perceptual control,…

Sternberg and Gastel have provided an example of a major principle of intelligence research--the relationship between a task's working memory demands and its sensitivity to individual differences in fluid intelligence and "g." There is no need to invoke additional constructs such as "novelty." (SLD)

It is asserted that the statistical arguments proposed by Humphreys are not supported by the formula he presents. The disagreement with Larson is with the contention that there exists one correct theoretical framework in which intelligence research should be posed. The respective viewpoints are seen as complementary, not competing. (SLD)

The hypothesis that coping with novelty is a key aspect of intelligence is not supported by the data of Sternberg and Gastel. It is contended that these authors committed a common error by interpreting correlations involving difference scores without reference to the properties of the components of the difference. (SLD)
