Abstract

Questions:
Will the N400 ERP be observed when participants read word pairs that are either related (semantically, causally, hierarchically, or associatively) or unrelated?

Will a replication of a study using word pairs with varying degrees of relatedness produce similar results to the model study in terms of N400 latency and amplitude?

Can results from a robust, easily-recognizable ERP be used to validate methods for the discovery of more subtle ERP’s?

Hypotheses:

It is expected that our results will mirror the findings of our model study, revealing significant negative-going neural activity between 200 and 500ms after seeing the stimulus. We anticipate this effect to be robust enough to identify as the N400 ERP. Further, we expect to be able to use these findings in later studies as a means of validating the methods and procedures for investigating more subtle ERP-related neurolinguistic events.
