Neurocognitive aging is associated with distinct patterns of changes in task-related brain activities in the aging brain. However, the brain mechanisms underpinning such changes are …
The present experiments investigated the influence of energetic cost of walking to a target on both the visually perceived egocentric distance of the target and …
Models of collective motion assume that pedestrians average over the entire neighborhood. However, there are many situations in which pedestrians are not averaging, such as …
Primates are capable of vast numbers of reach and grasp actions for a near infinite combination of perceived features. This essential primate behavior arises from …
Echolocating bats use an active perceptual system, also known as biosonar, that allows them to navigate and forage in complete darkness by emitting ultrasonic vocalizations …
On-line control and model-based control are two general approaches to visual control of human actions. When intercepting a moving target, humans appear to use the …
The local interactions between neighbors serve as the fundamental building blocks that give rise to human crowd behavior, but little is known about the actual …
In this thesis, I explore how objects affect the space around them. I show that spatial information is extracted from even completely novel objects. Information …
Visual selective attention helps to filter irrelevant information, integrate an object’s constituent visual features, and enhance cortical visual processing at the attended location. Motivated by …
Visual perceptual learning (VPL) goes through temporal dynamics of consolidation after the offset of visual training. This temporal dynamics of consolidation consists of at least …
Current models of cognitive control propose that the capacity to control one’s ongoing thoughts and actions is supported by a response threshold adjustment process involving …
Human brain processing declines with aging and reveals cognitive and perceptual impairments. Previous researches on cognitive neuroscience in aging have provided evidence on the relationship …
Most existing models of collision avoidance rely on distance as input, which is not biologically plausible for human pedestrians. Although they can replicate some crowd …
