A correction by Bond (TM 504 914) of an error by Tucker, Damarin, and Messick is acknowledged. A formula for the correlation between initial true test scores and true difference scores is presented. Observed score considerations should be replaced by emphasis on true score considerations. (Author/CTM)

Three-year olds who failed a false-belief pretest were trained in two groups on either the concept of belief or the concepts of desire and perception. Both groups showed improved performance on a false-belief posttest compared to a control group trained on number conservation. Results were interpreted as demonstrating coherence in children's…
