Although humans are the only species to possess language-driven abstract mathematical
capacities, we share with many other animals a nonverbal capacity for estimating quantities …

This is a survey of psychophysical studies of motion perception carried out mainly in the last
10 years. It covers a wide range of topics, including the detection and interactions of local …

Human perceptual decisions are often described as optimal. Critics of this view have argued
that claims of optimality are overly flexible and lack explanatory power. Meanwhile …

We have recently suggested that numerosity is a primary sensory attribute, and shown that it
is strongly susceptible to adaptation. Here we use the Method of Single Stimuli to show that …

An extraordinary variety of sight recovery therapies are either about to begin clinical trials,
have begun clinical trials, or are currently being implanted in patients. However, as yet we …

It is well known in the psychophysical literature that low visual contrasts can lead observers
to misestimate the speed of moving objects. This effect can have important consequences …

The notion that Bayesian processes are fundamental to brain function and sensory
processing has recently received much support, and a number of Bayesian accounts of how …

To reduce bird collisions on wind turbines, Automatic Detection Systems have been
developed to locate approaching birds and trigger turbines to slowdown to 2–3 rotations per …

Although estimating travel distance is essential to our ability to move through the world, our
distance estimates can be inaccurate. These odometric errors occur because people tend to …

Often, we have to rely on limited information when judging time-to-contact (TTC), as for
example, when driving in foul weather, or in situations where we would need reading …
