Interactions across time scales in speech perception
Flexibility is a key property of our perceptual system due to the richness and to the relative unpredictability of our environment. We investigated how flexible behavior can emerge from the interaction between fast perceptual dynamics, which adapt our perception to the environment "as fast as possible", with slower processes like habituation to the stimuli and learning. We tested some non trivial prediction raised by a nonlinear dynamical model of these interactions (Lancia and Winter, 2013). Also we used the model-guided parametrization of perceptual behavior to investigate the relations between perception of sounds without a linguistic content and sounds correspondng to speech events.
