Abstract : Work was completed on Lee Wurm's dissertation. This project examined the auditory processing of prefixed English words in order to test competing models. One group of models states that morphologically complex words must be decomposed prior to lexical access, while another states that they need not be. Mixed models have also been proposed. In Experiment 1 potential stimulus items were rated along various continua by approximately 120 subjects. These ratings were used in regression analyses in two subsequent experiments. In Experiments 2-3 recognition performance data were collected using a gating paradigm and a lexical decision paradigm (38 and 110 subjects, respectively). Overall, uniqueness points and frequency measures corresponding to full form prefixed words were much better predictors of performance than were measures corresponding to work roots. These results support a continuous processing strategy.
