Generality of likelihood ratio decisions.

摘要: A basic assumption of Signal Detection Theory - a special case Bayesian Decision is that decisions are based on likelihood ratios (the ratio hypothesis). In preceding paper, Glanzer et al. (2009) tested this in recognition memory tasks. The tests consisted formal proofs and computational demonstrations produce three regularities (1. the Mirror Effect, 2. Variance 3. z-ROC Length Effect). found implied do indeed hold for wide range item studies taken from literature. We now claim generally: about sensory events, reasoning, weather forecasting, etc. An examination past decision supports generalization. also report new experimental two additional areas, semantic mental rotation, further supporting results highlight optimal characteristics making contrast to current emphasis its inefficiencies.
