I am writing a chapter on the effect she presented and I hope to find others who were there and who remember the moment.<div class=""><br class=""></div><div class="">The results in the talk were also reported the article cited below, an extension of work by Tynan and Sekuler, adding a motion aftereffect test, and — this is the point of the chapter — an illusion of seeing a completed texture in the occluded central gap. She presented a movie, which I have, but the effect has not been replicated on video equipment.</div><div class=""><br class=""></div><div class="">Any memories would be appreciated.</div><div class=""><br class=""></div><div class="">Patrick Cavanagh</div><div class=""><br class=""></div><div class=""><img apple-inline="yes" id="D4A354D9-F282-4A81-BFA5-5B3D80DFA855" width="279" height="182" src="cid:6A921F83-0809-42F5-B002-879E7ECF130C@dartmouth.edu" class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">
