Am I wrong ? In vision studies, this factor (base category, super-ordonate category...) seems to modulates the results depending on the task used (lexical verification, rapide search...).<br> <br> <br> Sylvain Clément<br> <br> <br> <br> Brian Gygi a écrit : <blockquote cite="mid:W853021091158011189686045@xxxxxxxx" type="cite"><br> Ballas (1993) measured identification of environmental sounds that were truncated to 700 ms.
