Temporal Primitives in Auditory Cognition and Speech Perception - 2008

Explore the temporal aspects of auditory cognition and speech perception in this lecture by David Poeppel from the University of Maryland. Delve into the process of creating usable internal representations of speech input by breaking down signals into appropriate temporal units. Examine Poeppel's adaptation of Marr's approach to vision, focusing on linking neurobiological mechanisms like cortical oscillations and phase-locking to auditory cognitive representations such as syllables. Discover the multi-time resolution analysis required for sound pattern perception, with emphasis on two privileged time scales that form the basis for constructing elementary auditory percepts. Learn about recent experimental data from psychophysics, MEG, and concurrent EEG/fMRI supporting these 'temporal primitives'. Gain insights into the construction of internal representations mediating the analysis of speech and other acoustic signals. Cover topics including functional anatomy, analysis by synthesis, magnetoencephalography, data visualization, spatial resolution, oscillatory frequency, and the role of attention in plasticity.
