    Research Interests:

    ​My research investigates the stages of visual processing which occur within the first few seconds following an eye fixation and how they work together to give us a sense of the world around us. To address this broad issue, I am studying mental representations of ensembles of objects (i.e. statistical summary representations), such as trees of various orientations in a forest or birds of various sizes in the sky. Specifically, my research explores the relationship between summary representations and outlier objects, the effects of grouping on summary representations, and the integration of featural distributions within an ensemble into one statistical summary. Most recently, I have begun to investigate how regularities and patterns in a background can influence our visuo-spatial cognition by testing memory for various elements of both real-life and computer-generated scenes. One way to look at visuo-spatial representations is by measuring whether memory for a visual scene extends beyond the view boundaries, as this boundary extension error may be a fundamental process used to predict our visual environment beyond the information we are given.
