Subject: Re: [AUDITORY] Maximum temporal window for pattern recognition and the perception of redundancy From: Leon van Noorden <leonvannoorden@xxxxxxxx> Date: Fri, 3 Feb 2017 09:45:52 +0100 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--Apple-Mail=_2465B851-D970-4286-84CD-F7EFF2E3521C Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=us-ascii Dear Dario, dear list, An answer to your first question can be found in my quasi antique PhD = thesis: Temporal Coherence in the Perception of Tone Sequences. I found this kind of temporal window to be in the order of 2 seconds. > You can access the book feely on the website of the Technical = University Eindhoven: https://pure.tue.nl/ws/files/3389175/152538.pdf = <https://pure.tue.nl/ws/files/3389175/152538.pdf> Kind regards, Leon van Noorden www.ipem.ugent.be > On 01 Feb 2017, at 15:40, Dario Sanfilippo = <sanfilippo.dario@xxxxxxxx> wrote: >=20 > Hello, dear list. >=20 > I would like to ask you a couple of questions and I will be very = grateful if you could help me.
