Objective: We recently proposed a sequential processing schema for the equiprobable auditory Go/NoGo task, based on a principal components analysis (PCA) of event-related potentials (ERPs) from a university student sample. Here we sought to replicate the schema, and use it to explore processing in well-functioning older adults. Methods: We compared behavioural responding and ERPs of 20 independent-living older adults (M_age = 68.2 years) to data from a sex- and handedness-matched group of university students (M_age = 20.4 years). ERPs had substantial latency differences between the groups, and hence were subjected to separate group temporal PCAs. Results: Component ...
