For some experiments, a few presentations of the stimuli might be all what is necessary to ensure fairly stable thresholds in the following test phase, while for others, subjects have to go through hours of practice. I'm interested in perceptual learning in general, and in auditory perceptual learning in particular, and would like to use the list for an informal survey. My questions are: 1. Which tasks do and don't "train up"? And in tasks which do show a substantial training effect: 2. What is the time course of this learning? 3. What are the important parameters? like: amount and/or regularity of training retention after breaks measurement method and also: How does the initial threshold relate to the final threshold? (poor starters catching up, or a similar "dynamic range" for improvement?) How much does previous (hearing) experience matter? (e.g. is your favourite subject always the one with the lowest thresholds, and/or the fastest one to produce stable thresholds?) What is special in "special populations"? (e.g. musicians, piano tuners, hearing impaired, psychoacousticians...) I'd be happy to hear from you about your experiences, and also about references - i found lots in a "visual perceptual learning" search, but much less in the auditory version. many thanks, Marina --- Marina Rose University Laboratory of Physiology, Oxford, UK mailto:marina.rose(at) --------------7456883D23A2C061027D5C93 Content-Type: text/x-vcard; charset=us-ascii; name="marina.rose.vcf" Content-Transfer-Encoding: 7bit Content-Description: Card for Marina Rose Content-Disposition: attachment; filename="marina.rose.vcf" begin:vcard n:Rose;Marina tel;fax:0044 1865 272469 tel;work:0044 1865 272513 x-mozilla-html:FALSE org:;University Laboratory of Physiology adr:;;Parks Road;Oxford OX1 3PT;;; version:2.1 email;internet:marina.rose(at) x-mozilla-cpt:;7312 fn:Marina Rose end:vcard --------------7456883D23A2C061027D5C93--
