Multiple Visual Perspectives in Memories for Events
Memories for events, including autobiographical experiences, can be retrieved from an own eyes perspective, how events are typically formed, or from an observer-like perspective in which one see’s oneself in the memory. Adopting an observer-like perspective has long been thought to reflect the transformation of memories overtime. Consistent with that idea, remote memories are associated with a greater frequency of observer perspectives in memories, whereas recent memories are associated with more frequent own...
The effects of motivation-cognition interactions on skilled action
Most day-to-day activities clearly benefit from goal-directed cognitive control and enhanced motivation. However, many people have the intuition that exerting too much control over our actions can be harmful, especially when under pressure to perform. How does enhanced motivation affect cognitive control processes? How do these processes in turn affect skilled motor performance? What are the mechanisms by which enhanced motivation both supports and potentially hampers the activity of neural...
Factors that Influence Belief in True and False Headlines
Discerning between true and false news can be difficult. If people believe false news, it may influence important issues such as political elections, attitudes toward public policy, and health care decisions. This presentation will focus on factors that influence belief in headlines. Several individual...
Towards a multi-level framework for human-AI interaction
How can we develop AI systems that can competently, ethically, and autonomously interact with all people? Understanding how human physiological, affective, and cognitive processes interact with...
Developing a cognitive approach to the study of human crowd dynamics from interdisciplinary perspectives
Most crowd-related disasters can be attributed to human behavior, or to the design of the built environment. The existing literature point to how visual factors, like crowd density,...
Studying invariance of face dimensions at multiple representational levels
Many research questions in vision science involve determining whether two stimulus properties are represented “independently” or “invariantly” versus “configurally” or “holistically”. Ideally, we would want to appropriately define such representational properties and develop valid ways of measuring them. General recognition theory (GRT) is a multidimensional version of signal detection theory that has been proposed as a candidate for this task, but the...
The time course of visual and conceptual contributions to scene categorization
Visual scene understanding is remarkably rapid. Over the past two decades, a number of features have been hypothesized as mechanisms that facilitate this ability, ranging from low-level visual features such as color and contours, to high-level conceptual features such as attributes and affordances. However, significant correlations exist across these features, making it difficult to assess the independent contributions of any given feature to scene categorization. We obtained...
While it has long been known that advocating for a cause can alter the advocate’s beliefs, it is often assumed that this bias is controllable. Lawyers, for instance, are taught they can...
Revealing the role of hierarchical structure in visual motion perception
Bayesian inference has emerged as a successful description of elementary human visual motion perception, but little is known about how we make sense of the complex, nested motion relations found in real-world dynamic scenes. We developed a novel stimulus design that enabled us to address this question and to reveal (features of) the latent structured priors guiding visual motion perception. I will discuss two theory-driven psychophysics experiments: one probing the use of...
