Masked partial-word priming in visual word recognition: effects of positional letter frequency

Abstract

In 4 primed lexical decision experiments, it was found that the positional frequencies of letters shared by the prime and target relative to the overall positional letter frequency of the target determined the magnitude of priming effects. The lower the positional frequency of shared letters, the stronger the facilitatory effect observed. Both an interactive and noninteractive semistochastic version of the interactive activation model captured the principal trends in the data. It is argued that masked partial-word priming arises from a tradeoff between the facilitation generated by prime-target letter overlap and the inhibition generated from all lexical representations activated by letters in the prime that receive further support on target presentation.
