<p class="MsoNormal">Hi everyone,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This week's speaker in the University of Sydney Philosophy Seminar Series is Philippe Chuard, (Southern Methodist University, Dallas)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The title of the talk is "Postdictive Explanations". Here is an abstract for the talk:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">In the past 20 years or so, a number of cognitive psychologists and neuroscientists—some philosophers even—have advanced so-called “postdictive” models for a variety of perceptual phenomena, including the perception
of causation, colour-motion visual asynchrony, etc. Some have suggested that such postdictive mechanisms could naturally account for backward masking and beta-motion. The heralded paradigm which all these attempts invariably appeal to is Eagleman and Sejnowski’s
explanation of the flash-lag effect (2000) as the first successful instance of postdiction. Yet, two things should strike us as odd in this kind of rationale for postdiction. For one thing, none of these later appeals to postidiction seem to mean what Eagleman
and Sejnowski mean by that notion. Indeed, as we’ll see, there are in fact 4 notions of “postdiction”, and later uses don’t entail Eagleman and Sejnowski’s initial notion. For another, Eagleman and Sejnowski’s postdictive explanation of the flash-lag effect
isn’t as successful as it is widely assumed to be. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The seminar will take place at 3:30pm on Wednesday April 30 in the Philosophy Seminar Room (N494).<o:p></o:p></p>
