DESCRIPTION:The Centre for Research on Language\, Mind and Brain welcomes D
 r.\nBruce Schneider\, who will present a Distinguished Lecture entitled\n'
 How age affects auditory-cognitive interactions in speech\ncommunication.'
 \n\nDr.  Schneider (Psychology\, U of T) is Director of the CIHR\nResearch
  Group on Sensory and Cognitive Aging and Director of the\nCentre for Rese
 arch on Biological Communication Systems.\nAbstract:\nOlder listeners ofte
 n experience communication difficulties in\neveryday life.  For example\, 
 in noisy environments\n they often find it difficult to determine who is t
 alking and\nexactly what is being said.  These difficulties could be\ndue 
 to 1) hearing losses\, 2) age-related changes in cognitive\nfunctioning\, 
 or 3) both of these factors.  Because hearing\nstatus is highly correlated
  with cognitive performance in\nolder adults\, it is sometimes difficult t
 o ascertain whether\nthe communication difficulties experienced by them ar
 e a\nconsequence of age-related changes in auditory functioning\, or\nof c
 ognitive declines. For example\, to participate effectively in a\nmulti- t
 alker conversation\, listeners need to do more than\nsimply recognize and 
 repeat speech. They have to keep track of\nwho said what\, extract the mea
 ning of each utterance\, store it in\nmemory for future use\, integrate th
 e incoming information with\nwhat each conversational participant has said
  in the past\, and\ndraw on the listener’s own knowledge of the topic unde
 r\nconsideration to extract general themes and formulate\nresponses. In ot
 her words\, to acquire and use the information\ncontained in spoken langua
 ge requires the smooth and rapid\nfunctioning of an integrated system of p
 erceptual and\ncognitive processes.\nI will review evidence that the opera
 tion of this\nintegrated system of perceptual and cognitive processes is m
 ore\neasily disrupted in older than in younger adults\, especially\nwhen t
 here are competing sounds in the auditory scene.\nIn particular\, age-rela
 ted declines in auditory processing\nappear to impede stream segregation i
 n complex auditory\nscenes\, making it more difficult for the older adult 
 to attend to\nthe appropriate talker. To compensate for these auditory\nde
 clines\, older adults have to engage cognitive resources more\noften and m
 ore fully than do younger adults to help parse the\nauditory scene and rec
 over imperfectly-heard material\, leaving\nfewer resources for the higher-
 order tasks involved in speech\ncommunication.\n
