We have recently published a series of behavioural and brain imaging experiments that speak to your questions: Brain responses in humans reveal ideal observer-like sensitivity to complex acoustic patterns. https://www.ncbi.nlm.nih.gov/pubmed/26787854 Best wishes, Maria Maria Chait PhD Reader in Auditory Cognitive Neuroscience

On Behalf Of Dario Sanfilippo Hello, dear list. I would like to ask you a couple of questions and I will be very grateful if you could help me. It would be great to be pointed out to specific publications, thank you so much
in advance for that. The first question is on the maximum temporal window for the recognition of patterns in long-term audio events. Generally speaking, what is the largest (temporal) distance between
audio events so that we can still process such events as interrelated? As an example, let's assume to have a sequence of different pitches equally spaced in time; what is the largest possible distance between them to still be able to perceive a melody? The second question is on the perception of redundancy in relatively complex (i.e., dynamical equilibrium) long-term audio events. As an example, think of the sound of the sea:
its internal structure is never the same although it keeps a strong identity from a global point of view. I believe that this is highly dependent on both the cultural background of the listener as well as the degree of complexity of the audio event itself,
but is there any study which tries to relate the perception of redundancy (i.e., the moment in which the listener's attention drops) with a specific temporal window? And is there a connection or similarity between this window and the one described in my first
question? Thank you and best wishes.
