Auditory Temporal Processing, Speech Perception & Aging

The biggest communication complaint of older people is understanding speech in degraded conditions.  We examine the general hypothesis that some of these difficulties are related to underlying problems in auditory temporal processing.  Research from the laboratory shows that degraded speech that involves alteration of the duration of individual phonemes and/or prosody is associated with strong age-related recognition deficits (e.g, Gordon-Salant et al., 2008).  These forms of speech alteration occur in Spanish-accented English, and indeed, age effects are observed for recognition of this type of accented speech (Gordon-Salant et al., 2010a, b).  Results from our psychoacoustic studies demonstrate that large age-related deficits also occur for judgments about the rhythm and stress of stimulus sequences (Fitzgibbons & Gordon-Salant, 2010).

The current project assesses the effects of age, hearing loss, and linguistic experience on the perception of altered stress and timing cues in accented English and non-speech sequences.  Building on prior work (Fitzgibbons & Gordon-Salant, 2011; Gordon-Salant et al., 2010c), the project also will compare intervention techniques to facilitate auditory learning of accented speech and non-speech sequences by older people.

An important new direction of the project is to examine questions about the role of auditory-visual (AV) temporal asynchrony on age-related differences in perception of speech during AV tasks.  All of the experimentsexamine the contributions of peripheral hearing loss, type and degree of stimulus temporal complexity, and altered cognitive demands on auditory processing of young and elderly listeners using speech and non-speech stimulus sequences.
