Current Lab Members
Stephen Killingsworth —
Stephen started graduate work in the lab in 2006. He has been involved in work under our NSF grant to study people's beliefs about computer and robotic systems. Specifically, he's looked at how people think these may represent ongoing human actions. Stephen's other work has looked at connections between perception and action, including how knowledge about an object's function affects visual perception and action production.
Alex joined the lab in the summer of 2001 at Kent State, and received his PhD in 2005. His work focused on visual working memory, change blindness, and inattentional blindness. His dissertation looked at the relationship between attention and visual working memory. He is now an assistant professor at Knox College.

Bonnie was a grad student in the lab when we were at Kent State, and completed her PhD in 2003. Her research focuses on the phenomenon of change blindness. Her masters thesis explored the degree to which failure to compare existing representations can cause change blindness (Angelone, Levin, & Simons, 2003), and her dissertation explored the impact of dual-task distraction on incidental change detection. While in the lab, Bonnie also worked on research using psychophysical tasks to understand same-race and cross-race face perception.

Melissa started in the lab in the fall of 1998, and completed her PhD in 2003. Her research focused on visual metacognition and change blindness. Melissa's thesis explored the degree to which people understand that mental effort is necessary to detect changes (Beck & Levin, 2003) and her more recent work has explored the degree to which people detect changes to "stable" or "unstable" properties more readily (Beck, Angelone, & Levin, 2004), an article that was selected for coverage in the APA monitor!! Other research explores the degree to which overwriting contributes to change blindness (Beck & Levin, 2002).

Joe received his PhD from Kent State in the summer of 2003, and currently holds an instructor position at Depauw University, but he just received and accepted an offer for a tenure track position in the Psychology department at the Loyola University in New Orleans. His research explores the relationship between vision and audition. In his dissertation, Joe explored inattention blindness for noxious multimodal stimuli. In these experiments, subjects attended to one event (a group of people passing a basketball) while another event unexpectedly occurred (someone walked into the scene and scraped their fingernails down a blackboard). Despite the salience of the event, about 50% of subjects were unaware of it.
Yukari worked in the lab on several projects, so although her advisor at Kent was Larry Melamed (Yukari completed her PhD in the fall of 2002), we count her as a lab alum anyway. Yukari is interested in the neurological bases of autism and in visual processing of natural objects. While at Kent she worked on a project exploring the bases of category-specific visual agnosia (Takarae & Levin, 2001), and one in which we explored visual search for real world objects (Levin, Takarae, Miner, & Keil, 2001).
