Four strategies used in judgment patterns were explored. Problem sets in which each solution strategy produces a unique solution pattern are depicted. Several experiments had been conducted using rules in this way with subjects from grade 4 through college. Problems were set in the context of concrete events which could be related, and subjects…

This report provides an overview of eight experiments on covariation judgment training. Included are a literature review, rationale, and description of the rule-analytic approach used in all experiments. Experiment 1 identified undergraduates' understandings of rule use, finding self-report a poor method for diagnosing sources of error. Experiment…
