Achromatic (luminance) vision is used by animals to perceive motion, pattern, space and
texture. Luminance contrast sensitivity thresholds are often poorly characterised for …

There is evidence that humans rely on an earth gravity (9.81 m/s²) prior for a series of tasks
involving perception and action, the reason being that gravity helps predict future positions …

A hypothesis gaining increasing popularity is that laypeople's representations of physical
phenomena might be driven by internalized physical laws. In three experiments, we tested if …

Schizophrenia and autism spectrum disorder (ASD) can disrupt cognition and consequently
behaviour. Traits of ASD and the subclinical manifestation of schizophrenia called …

Humans expect downwards moving objects to accelerate and upwards moving objects to
decelerate. These results have been interpreted as humans maintaining an internal model …

Obtaining reliable estimates of the time-to-contact (TTC) in a three-dimensional (3D)
parabolic trajectory is still an open issue. A direct analysis of the optic flow cannot make …

In a 2-alternative forced-choice protocol, observers judged the duration of ball motions
shown on an immersive virtual-reality display as approaching in the sagittal plane along …

Virtual reality is used to manipulate sensorimotor interactions in a controlled manner. A
critical issue is represented by the extent to which virtual scenarios must conform to physical …

We move our eyes to place the fovea into the part of a viewed scene currently of interest.
Recent evidence suggests that each human has signature patterns of eye movements like …

Aristotle believed that objects fell at a constant velocity. However, Galileo Galilei showed
that when an object falls, gravity causes it to accelerate. Regardless, Aristotle's claim raises …
