[Probcogsci] Probcogsci meetings

[Angela Yu]

Dear all,

We will continue discussing Teh's Pittman-Yor Process paper this  
Friday, which Mike will kindly lead again.

Next week's meeting (2/12) is canceled due to Cogsci department's  
prospective grad students open house.

The week after (2/17), Leanne Chukoskie, will give a talk on her eye  
movement research -- see abstract below.


Effects of implicit learning in eye movement search
Deciding where to look next demands the integration of bottom-up image  
salience with top-down goals, motivation and past experience. Most  
research has focused on the characteristics of the image regions; less  
attention has been given to the role of top-down influences despite  
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  
can control the association of a spatial region with reward and assess  
how implicit learning contributes to where we look next.



See you all on Friday,
Angela
