Abstract:

A dual-route approach was used as an initial framework to examine the relations among presentation format and lexical processing in an naming task. In Experiments 1 and 3, words were presented in lower-case vs. case-alternated format. Presentation format interacted with word frequency and regularity: for irregular words (e.g., pint), case alternation was additive with frequency, whereas for regular words (e.g., mint), case alternation and frequency interacted. Experiment 2 dissociated the locus of case- alternation effects from those of stimulus intensity. Stimulus intensity was additive with frequency and regularity suggesting that whereas stimulus intensity affects encoding, case alternation affects lexical processing at a post-encoding stage in the word recognition system. It is concluded that a dual-route approach provides a suggestive but incomplete account of how case alternation influences lexical processing. As an alternative to a dual- route approach, we show that the present results can be addressed and successfully simulated using an implemented version of Norris's (1994) multilevel model.
