This experiment used the masked priming lexical decision task to address previous contradictory evidence about the relative strength of priming for (i) transparent pairs (e.g., "worker" "WORK") which are morphologically and semantically related; (ii) opaque pairs (e.g., "corner" "CORN") which appear to be morphological relatives but are not…

Early acquired words are processed faster than later acquired words in lexical and semantic tasks. Demonstrating such age of acquisition (AoA) effects beyond reasonable doubt, and then investigating those effects empirically, is complicated by the natural correlation between AoA and other word properties such as frequency and imageability. In an…

Because of its potential importance for word learning, children's judgment of whether they know names for objects was investigated. In Study 1, judgment accuracy was at or near ceiling in about two-thirds of 4-year-olds, and covaried with judgment of word familiarity and with justifying novel name mapping in terms of avoidance of name overlap. The…
