Previous work indicates that semantic categorization decisions for nonexemplars (e.g., deciding that TURBAN is not an animal name) are faster for high-frequency words than low-frequency words. However, there is evidence that this result might depend on category size. When narrow categories are used (e.g., Months, Numbers), there is no frequency…

Participants were German dyslexic readers (13-year-olds) who--compared to English dyslexic readers--suffer mainly from slow laborious reading and less from reading errors. The eye movements of eleven dyslexic boys and age-matched controls were recorded during reading of text passages and pseudoword lists. For both text and pseudoword reading, the…

This article contrasts aphasic patients' performance of word naming and lexical decision with that of intact college-aged readers. We discuss this contrast within a framework of self-organization; word recognition by aphasic patients is destabilized relative to intact performance. Less stable performance shows itself as an increase in the…

This paper describes a Hebrew naming test that consists of 48 line drawings ordered by word frequency. The initial validation phase included 48 young adults (ages 20-28), 48 old adults (ages 67-85), and 27 individuals with Alzheimer's disease (ages 68-87). Results indicated a modest odd-even internal consistency effect, word frequency effect, and…
