There are many ways to be rich: Effects of three measures of semantic richness on visual word recognition

@article{citeulike:2304459, abstract = {Previous studies have reported that semantic richness facilitates visual word recognition (see, e.g., Buchanan, Westbury, \& Burgess, 2001; Pexman, Holyk, \& Monfils, 2003). We compared three semantic richness measures—number of semantic neighbors (NSN), the number of words appearing in similar lexical contexts; number of features (NF), the number of features listed for a word's referent; and contextual dispersion (CD), the distribution of a word's occurrences across content areas—to determine their abilities to account for response time and error variance in lexical decision and semantic categorization tasks.
