Welcome
to the Cognition, Hearing and Training (CHAT) Lab
Research in the CHAT lab focuses on the role of cognitive factors in speech perception. Current studies explore the effects of limited processing capacity on the perception of speech in the presence of competing speech (the "cocktail party problem") in younger and older adults.
This section is under revision.
Equipment
The CHAT lab uses two rooms in Pierce Hall on the Purdue University Campus (183 & 184) for data collection and analysis. The testing room is currently set to test or train up to four participants simultaneously, using Dell Dimension Windows XP workstations equipped with E-Prime experiment control software, a Cedrus RB-620 millisecond-accurate response box and Sennheiser HD-25 headphones. Some research is also conducted in the audiology clinics at Purdue University. Stimulus generation, manipulation and analysis is done using Praat or Matlab. We also have professional quality recording equipment with access to the Audiology Clinic soundbooths for recording, and we receive support from an excellent electronics shop. Through collaborations with colleagues in Health Sciences and Biomedical Engineering we also have the potential to conduct research using a variety of MR imaging methods, including fMRI and MR spectroscopy.
