Compensatory and Serial Processing Models for Relating Electrophysiology, Speech Understanding, and Cognition.

ABSTRACT:

Objectives

The objective of this study was to develop a framework for investigating the roles of neural coding and cognition in speech perception.

Design

N1 and P3 auditory evoked potentials, QuickSIN speech understanding scores, and the Digit Symbol Coding cognitive test results were used to test the accuracy of either a compensatory processing model or serial processing model.

Results

The current dataset demonstrated that neither the compensatory nor the serial processing model were well supported. An additive processing model may best represent the relationships in these data.

Conclusions

With the outcome measures used in this study, it is apparent that an additive processing model, where exogenous neural coding and higher order cognition contribute independ
