Department of Psychology, Oregon State University, Corvallis, 97331, USA
Psychol Aging 21:431-47. 2006..The authors conclude that greater cumulative experience with lexical processing leads to greater automaticity, allowing older adults to more efficiently perform this stage in parallel with another task... - The role of input and output modality pairings in dual-task performance: evidence for content-dependent central interferenceEliot Hazeltine

NASA Ames Research Center, Moffett Field, CA, USA
Psychol Res 70:494-503. 2006..We conclude that practice can eliminate the bottleneck limitation, but performance is still subject to other sources of interference, such as competition between central codes of the two tasks... - Modality pairing effects and the response selection bottleneckEliot Hazeltine
