Abstract:

Memory is critical to our ability to discover statistical regularities in our surroundings and in communication signals such as music and language. Despite growing empirical accounts of our sensitivity to structures in acoustic sequences, longstanding questions pertain to how mnemonic traces form and under what conditions.

In this talk I will present a series of experiments combining behavioural manipulation and modelling to investigate the dynamics of memory formation for acoustic patterns and the effects of long-term and contextual priors on sound perception. I will show that healthy listeners change their behaviour in response to acoustic patterns to which they are exposed sparsely and only a few times. Remarkably, the memory for these patterns is implicit and lasts for months after initial exposure. Moreover, I will present how the use of pupillometry allows testing listeners’ sensitivity to long-term and contextual priors during music perception mirroring real-word listening situations in which we automatically glean information from sound streams.
