Daily activities require agents to interact with each other, such as during collision avoidance. The nature of visual information that is used for a collision free interaction requires further understanding. We aim to manipulate the nature of visual information in two forms, global and local information appearances. Sixteen healthy participants navigated towards a target in an immersive computer-assisted virtual environment (CAVE) using a joystick. A moving passive obstacle crossed the participant's trajectory perpendicularly at various pre-defined risks of collision distances. The obstacle was presented with one of five virtual appearances, associated to global motion cues (i.e., a cylinder or a sphere), or local motion cues (i.e., only the legs or the trunk). A full body virtual walker, showing both local and global motion cues, used as a reference condition. The final crossing distance was affected by the global motion appearances, however, appearance had no qualitative effect on motion adaptations. These findings contribute towards further understanding what information people use when interacting with others.

In cluttered and complex natural scenes, selective attention enables the visual system to prioritize relevant information. This process is guided not only by perceptual cues but also by imagined ones. The current research extends the imagery-induced attentional bias to the unconscious level and reveals its cross-category applicability between different social cues (e.

Path integration, the ability to track one's position using self-motion cues, is critically dependent on the grid cell network in the entorhinal cortex, a region vulnerable to early Alzheimer's disease pathology. In this study, we examined path integration performance in individuals with subjective cognitive decline (SCD), a group at increased risk for Alzheimer's disease, and healthy controls using an immersive virtual reality task. We developed a Bayesian computational model to decompose path integration errors into distinct components.

Gaze stabilization is important to animals because it allows them to visually differentiate between their own motion relative to their environment and the motion of objects within their environment. Animals can struggle to stabilize their gaze in environments that have a high amount of visual noise. In shallow aquatic environments, such as tidal creeks, the motion of the water's surface can create dynamic spatiotemporal fluctuations in illumination referred to as "caustic flicker.

Anterior Cruciate Ligament (ACL) injuries are a major concern in sports, especially among athletes with limited ankle dorsiflexion, impacting performance and career longevity. Targeting kinetic and kinematic risk factors of high-risk sports actions through effective strategies is crucial for injury mitigation. This study aimed to assess the impact of internal focus (IF), and external focus (EF) within linear (LP) and differential learning (DL) methods on movement quality of a single leg drop jump (SL-DJ) task training in male handball players with restricted ankle dorsiflexion.

Motion in visual images can be described in terms of changes in phases of Fourier components (phase cues), or displacements in the position of specific features (position cues) over time. Human observers are able to perceive motion using both cues, where perceived direction of motion is biased in favour of phase cues at higher spatial and temporal frequencies, and in favour of position cues at lower spatial and temporal frequencies. This suggests the existence of separable mechanisms for processing phase and position cues.
