An Interactive Activation Model of the Effect of Context in Perception. Part 2

Abstract : This paper is the second part of a two-part series introducing an interactive activation model of context effects in perception. In the previous part we developed the basic form of the model and showed how it accounts for several of the fundamental phenomena of work perception. In this part, we first present a number of new experiments and show how the model accounts for these experiments. Then we propose a number of extensions of the model to such cases as spoken input, pronunciation tasks, and words embedded in sentential context. Finally, we discuss the strengths and weaknesses of the model, pointing out further possible extensions of the model to account for aspects of word perception currently ignored. The new experiments all revolve around what we call the 'context enhancement effect.' These experiments are designed to assess the roles of direct and indirect evidence concerning the identity of a letter in an input string.
