About Me

I am a cognitive psychologist working at the intersection of human and artificial intelligence. I am interested in the capabilities and limitations of human and artificial minds and applying insights from human cognition to improve the behavior of artificial systems.

Who can re-enter the loop? A scoping review on cognitive abilities and task re-engagement in human-AI interaction

Rapid advances in artificial intelligence (AI) promise a near future in which humans and AI systems work together to solve complex problems. Although offloading tasks to AI reduces immediate cognitive demands, the system may later require human input or decision-making, at which point the human must “re-enter the loop” by redirecting attention, reconstructing the task state, and responding appropriately. Whether individual differences in cognitive ability predict the capacity to re-enter the loop remains unclear. …

From visual search to movement control: A priority field for artificial agents

From visual search to movement control: A priority field for artificial agents

Human observers prioritize visual information according to task goals. Most computational models of naturalistic viewing are gaze-trained for free viewing, leaving open whether goal-directed attention can emerge in systems without gaze supervision. We tested two off-the-shelf vision-language models (VLMs), Qwen3-VL-32B-Thinking and Gemma-4-26B-A4B-it, on 4,887 naturalistic scenes under visual-search and free-viewing instructions. Model predictions were compared with human fixations on the same images under …

Emergent goal-directed attention in large vision-language models

PupEyes: An interactive Python library for eye movement data processing

We present PupEyes, an open-source Python package for preprocessing and visualizing pupil size and fixation data. PupEyes supports data collected from EyeLink and Tobii eye-trackers as well as any generic dataset that conforms to minimal formatting standards. Developed with current best practices, PupEyes provides a comprehensive pupil preprocessing pipeline and interactive tools for data exploration and diagnosis. In addition to pupil size data, PupEyes provides interactive tools for visualizing fixation data, …

Attentional capture by abrupt onsets: Foundations and emerging issues

The study of attentional allocation due to external stimulation has a long history in psychology. Early research by Yantis and Jonides suggested that abrupt onsets constitute a unique class of stimuli that captures attention in a stimulus-driven fashion unless attention is proactively directed elsewhere. Since then, the study of visual attention has evolved significantly. This article revisits the core conclusions by Yantis and Jonides in light of subsequent findings and highlights emerging issues for future …

The temporal dynamics of visual attention

The temporal dynamics of visual attention

Researchers have long debated how humans select relevant objects amid physically salient distractions. An increasingly popular view holds that the key to avoiding distractions lies in suppressing the attentional priority of a salient distractor. However, the precise mechanisms of distractor suppression remain elusive. Because the computation of attentional priority is a time-dependent process, distractor suppression must be understood within these temporal dynamics. In four experiments, we tracked the temporal …
