[Probcogsci] Leanne Chukoskie Talk: Effects of implicit learning in eye movement search

[Angela Yu]

For this week's Probabilistic Models of Cognitive Science reading  
group meeting, Leanne Chukoskie will be talking about her work on eye  
movements this Friday at 1-2 PM in the Nat Comp Lab Seminar Room (2nd  
floor, SSRB).   The entrance to the lab is right by the elevator, call  
lab phone to be let in, if you don't have a personal code.

Hope to see you all on Friday.

Best wishes,
Angela

> Deciding where to look next demands the integration of bottom-up image

> their importance. Here, we explicitly manipulated prior experience by
> “hiding” reward locations and asking human and monkey subjects to
> conduct an eye movement search for the rewarded locations. Over the
> course of single experimental sessions, subjects redirected their gaze
> to the estimated center of the rewarded target distribution. The
> distribution of subjects’ eye movements also reflected the spread of
> the distribution. Thus, using this novel eye movement search task, we

> how implicit learning contributes to where we look next.
