Abstract
The article presents a commentary on the accompanying six papers from the perspective of a cognitive psychologist. Treisman's (1964, 1969) levels of analysis model of selective attention is suggested as a framework within which the interactions between 'bottom-up' auditory factors and 'top-down' cognitive factors may be understood. The complementary roles of auditory and cognitive aspects of hearing are explored, and their mutually compensatory properties discussed. The findings and ideas reported in the six accompanying papers fit well into such a 'levels of processing' framework, which may therefore be proposed as a model for understanding the effects of aging on speech processing and comprehension.
