August 2023:
New paper out: The role of color in transsaccadic object correspondence. (Journal of Vision).
This is Jes' first paper from the VPC Lab.
In this study, we tested whether color is consulted in transsaccadic object correspondence. We used two versions of the intrasaccadic target displacement task. We found that large color changes can disrupt stability for both direction and movement tasks, but not as strongly as blanking does. Interestingly, even smaller color changes, but not blanking, reduced response biases.

February 2023:
VPC Lab is going to VSS!
VPC lab members will present three posters during the annual meeting of Vision Sciences Society in May:
Saccadic adaptation changes perception of the saccade target object (Sunday, May 21, 8:30am) - Jes Parker & Madeline Embrey
Task design effects on negative search templates (Sunday, May 21, 8:30am) - Mike Mugno
The effects of saccades on visual working memory representations (Monday, May 22, 8:30am) - Golnaz Forouzandehfar & Garrett Hensley
Congratulations, everyone!
December 2022:
New paper out: A multi-method approach to addressing the toddler data desert in attention research. (Cognitive Development). This was a project in collaboration with Dr. Anastasia Kerr-German.
From the abstract: We collected simultaneous neural recordings (using functional near-infrared spectroscopy), eye-tracking, and behavioral responses in 2.5- and 3.5-year-olds to examine the neural and behavioral associations between these skills. Results revealed that oculomotor facilitation in the IOWA task was negatively associated with accuracy on neutral trials in the Flanker task. Second, conflict scores between the two tasks were positively associated.
June 2022:
New paper out: Tracking flanker task dynamics: Evidence for continuous attentional selectivity. (JEP:HPP). This is Kaleb's first paper from the VPC Lab.
From the abstract: We examined spatial and temporal movement dynamics for characteristics of continuous and discrete shifts in attentional selectivity. Our results showed that attentional selectivity increases gradually over time, rather than abruptly, demonstrating a continuous process of selective attention.
Jes & Mike received Elsevier/Vision Research Student Travel Award from VSS! Congratulations, both!

Last Zoom meeting: We had our last Zoom lab meeting. It was sad that we could not have our traditional end-of-year gathering, especially since four of our RAs (Brett, Cat, Divya, and Megan) graduated this semester. Here's a screenshot of our last meeting. See you all in person next Fall!

January 2021:
New paper out: Object-mediated overwriting across saccades (in press: Journal of Vision)
From the abstract: We tested the hypothesis that, when the two representations are perceived to belong to the same object, the
post-saccadic value tends to overwrite the pre-saccadic value. Substantial overwriting of the pre-saccadic color by the post-saccadic color was observed. Moreover, the introduction of a brief post-saccadic blank interval (which disrupted the perception of object correspondence) led to a substantial reduction in overwriting.
