Eye movements during free viewing to maximize scene understanding Open
What humans look at and do when freely viewing a scene is not well understood. We measure observer eye movements under different instructions while participants view a customized set of image pairs containing small visual alterations that …

The psychophysics of dynamic gaze-following saccades during search Open
The ability to quickly and precisely follow another person's gaze reflects critical evolutionary mechanisms underlying social interactions, such as attention modulation and the prediction of others' future actions. Recent studies show that…

Emergent neuronal mechanisms mediating covert attention in convolutional neural networks Open
Covert visual attention allows the brain to select different regions of the visual world without eye movements. Predictive cues of a target location orient covert attention and improve perceptual performance. In most computational models, …

Distinct mechanisms of configural face processing based on the preferred point of fixation on the face Open
Accurate face recognition relies on discerning subtle differences in the shapes (featural information) and relative positions (configural information) of facial features. When recognizing faces, most humans consistently land their first fi…

Semantic Saliency from Multi-Modal Large Language Model Scene Understanding Maps Open
Image-computable low-level image saliency has shaped perceptual psychology and computer science, but is limited by its inability to capture human high-level cognitive factors that influence attention and eye movements. A recent paper has s…

Distinct Roles of Central and Peripheral Vision in Rapid Scene Understanding Open
Central and peripheral vision loss, caused by conditions such as age-related macular degeneration and retinitis pigmentosa, disrupt visual processing in distinct ways, yet their impact on natural scene perception remains poorly understood.…

The Curious Mind: Eye Movements to Maximize Scene Understanding Open
Human eye movements while identifying a face, searching for targets, and executingmotor actions are directed to regions contributing to task accuracy. However,what humans look at and do when free-viewing a scene without a specific task isn…

A Deep Learning Framework for Predicting Functional Visual Performance in Bionic Eye Users Open
Efforts to restore vision via neural implants have outpaced the ability to predict what users will perceive, leaving patients and clinicians without reliable tools for surgical planning or device selection. To bridge this critical gap, we …

Predicting Reaction Time to Comprehend Scenes with Foveated Scene Understanding Maps Open
Although models exist that predict human response times (RTs) in tasks such as target search and visual discrimination, the development of image-computable predictors for scene understanding time remains an open challenge. Recent advances …

View article: Preferred fixation position and gaze location: Two factors modulating the composite face effect
Preferred fixation position and gaze location: Two factors modulating the composite face effect Open
Humans consistently land their first saccade to a face at a preferred fixation location (PFL). Humans also typically process faces as wholes, as evidenced by perceptual effects such as the composite face effect (CFE). However, not known is…

Convolutional Neural Network Model Observers Discount Signal-like Anatomical Structures During Search in Virtual Digital Breast Tomosynthesis Phantoms Open
Model observers are computational tools to evaluate and optimize task-based medical image quality. Linear model observers, such as the Channelized Hotelling Observer (CHO), predict human accuracy in detection tasks with a few possible sign…

From Text to Pixel: Advancing Long-Context Understanding in MLLMs Open
The rapid progress in Multimodal Large Language Models (MLLMs) has significantly advanced their ability to process and understand complex visual and textual information. However, the integration of multiple images and extensive textual con…

How the Curious Mind Uses Free-Viewing Eye Movements to Maximize Scene Understanding Open
What humans look at and do when freely viewing a scene is not well understood. We show that free-viewing fixations resemble those of observers describing scenes but differ from those of observers counting or searching for objects. Fixation…

Greater benefits of deep learning-based computer-aided detection systems for finding small signals in 3D volumetric medical images Open
Purpose: Radiologists are tasked with visually scrutinizing large amounts of data produced by 3D volumetric imaging modalities. Small signals can go unnoticed during the 3d search because they are hard to detect in the visual periphery. Re…

Emergent human-like covert attention in feedforward convolutional neural networks Open
Covert attention allows the selection of locations or features of the visual scene without moving the eyes. Cues and contexts predictive of a target's location orient covert attention and improve perceptual performance. The performance ben…
