Green, Samuel B. – Multivariate Behavioral Research, 1991
An evaluation of the rules-of-thumb used to determine the minimum number of subjects required to conduct multiple regression analyses suggests that researchers who use a rule of thumb rather than power analyses trade simplicity of use for accuracy and specificity of response. Insufficient power is likely to result. (SLD)

Using a narrative procedure, this study replicated Zaitchik's (1991) result that children are more likely to acknowledge another's belief when they are told about reality than when they see reality for themselves. The article argues that these children were acknowledging alternative rather than false belief. (20 references) (Author/CK)
