PROGRAMME 2017-2018

Bob Carlyon (MRC Cognition & Brain Sciences Unit, Cambridge, Englan) : "Pitch perception in acoustic and electric hearing: Hunting down the missing fundamentals"

Ce colloquium aura lieu exceptionnellement lieu en Dussane (45 rue d'Ulm) de 11h30 à 13h.

Résumé :
Pitch perception is important not only for the enjoyment of music and for the perception of prosody in speech, but also for our ability to process one sound, such as a voice, in the presence of competing sounds. Poor pitch perception, and the resulting difficulties when listening in noisy situations, are a common source of disability in deaf patients whose hearing has been restored by a cochlear implant (CI). I will summarise some experiments that address the following questions; (i) What aspects of the auditory-nerve response to sound are crucial for good pitch perception by normal hearing (NH) listeners? (ii) What is the biological basis for the severe limitations in pitch perception experienced by CI users? (iii) Are these limits fixed, or can they be partially overcome by the chronic electrical stimulation that occurs in the months following activation of a patient’s CI?, (iv) can pitch perception by CI users be improved by a drug that modulated fast-acting potassium channels? The experiments involve a combination of NH psychoacoustics, investigation of an illusory percept, CI psychophysics, electrophysiological recordings, and the results of a double-blind placebo-controlled drug trial. I will also briefly describe other experiments from our lab that aim to improve hearing by CI listeners.

Bahador Bahrami : "Wisdom, madness, and kindness of Crowds: What is the adaptive value of collective decision making?"

Résumé :
Many of us believe that two heads are better than one. Almost all of us also believe that too many cooks spoil the broth. Social psychology has provided evidence for both views raising the question if groups are not particularly better than individuals, what is the point of making decisions together? In my talk I will explore this question and suggest that consistent collective benefit is indeed real and achievable but not in the form of choice accuracy. You will have to sit through the talk - I am afraid - to see what my alternative is.
