Does Cogmed training improve the intelligibility of speech in noise, when materials are predicted to load highly on working memory?

Institution: Queens University

Investigator(s): Ingrid Johnsrude, Ph.D., Cheryl Hamilton

Program: Cogmed RM/ Cogmed QM

Background & Aim: The aim of this research is to evaluate whether Cogmed will improve intelligibility of speech in noise when the materials are associated with a higher processing load (i.e., low-context and high-ambiguity sentences). This will result in overall greater intelligibility, and a smaller difference in intelligibility between high- and low-context sentences, and between low- and high-ambiguity sentences.

Population & Sample Size: 30 typically functioning adults, ages 35 – 65 years

Design: Randomized, Placebo controlled, Test-retest
