E. D. Rie and H. E. Rie (see record 1978-27952-001) concluded that Ritalin enhances story recall after a 2-hr retention interval but not after 2 days and that the lack of difference in later recall argues against a facilitation of scholastic achievement due to Ritalin. The present author argues that the former conclusion is questionable because of inappropriate statistical analyses and because of the effects of confoundings contained in the experimental design. The latter conclusion, it is stated, appears to arise from the misconception of equating achievement with long-term memory independently of amount learned. Achievement is a function of both learning and memory, and the distinction should be maintained in examining Ritalin's effects. (2 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved)
