Relationships of similar scales (occupation vs occupation and occupation vs college major) for the Strong Vocational Interest Blank and the Kuder Occupational Interest Survey, Form DD, were assessed over a 1-yr. period. Results suggest caution in the interpretation of particular scale points for such procedures and in using these procedures to supplement each other for counseling purposes.

3 experiments were performed to clarify the relationship of two principles of cognitive control to the recall of different types of stimulus material. Exp. I shows that there is little or no relationship between leveling-sharpening and recall of thematic material and no relationship to recall of sequentially presented, highly similar designs. Exps. II and III show that, as predicted, field-articulation or field-dependence is related to the recall of similar visual designs but not to the recall of thematic material.

Validity and reliability findings are presented for new group forms of Thurstone's Color-Word Test and Voth's Autokinetic Test. Split-half, alternate, or shortened forms were constructed of several other old and new cognitive control tests and some key intellectual ability tests to explore the reliability of chese procedures and the possibility of using shortened forms. The results suggest that important savings in testing time may be achieved in exploratory studies by using the procedures described here.

Findings are presented to show the situational and temporal (over 1 yr.) stability of performance in the Lines Contrast Test, a measure of a new principle of cognitive control called “Contrast Reactivity.”

Test-retest rs over a period of 1 yr. are presented for scores from group tests of cognitive controls and intellectual abilities for which validity and split-half or short-form reliability estimates were reported earlier by Gardner and Lohrenz (1969). In spite of limitations on the possible reliabilities of certain scores, the reliability estimates obtained for these time-saving group procedures suggest that they can be used effectively for most purposes.
