  1. At what sample size do correlations stabilize?Felix D. Schönbrodt & Marco Perugini - unknown
    Sample correlations converge to the population value with increasing sample size, but the estimates are often inaccurate in small samples. In this report we use Monte-Carlo simulations to determine the critical sample size from which on the magnitude of a correlation can be expected to be stable. The necessary sample size to achieve stable estimates for correlations depends on the effect size, the width of the corridor of stability, and the requested confidence that the trajectory does not leave this corridor (...)

  • Inherently Ambiguous: Facial Expressions of Emotions, in Context.Ran R. Hassin, Hillel Aviezer & Shlomo Bentin - 2013 - Emotion Review 5 (1):60-65.
    With a few yet increasing number of exceptions, the cognitive sciences enthusiastically endorsed the idea that there are basic facial expressions of emotions that are created by specific configurations of facial muscles. We review evidence that suggests an inherent role for context in emotion perception. Context does not merely change emotion perception at the edges; it leads to radical categorical changes. The reviewed findings suggest that configurations of facial muscles are inherently ambiguous, and they call for a different approach towards (...)
