Three classes of task appear to involve time-to-contact (TTC) information: coincidence
anticipation (CA) tasks, relative judgment (RJ) tasks, and interceptive actions (IAs). An …

Bringing about desirable collisions (making interceptions) and avoiding unwanted collisions
are critically important sensorimotor skills, which appear to require us to estimate the time …

Athletes are dependent upon a constant supply of accurate and reliable information from the
environment whilst performing complex movements. Visual Perception and Action in Sport …

How might one account for the organization in behavior without attributing it to an internal
control structure? The present article develops a theoretical framework called behavioral …

Current theory proposes that baseball outfielders catch fly balls by selecting a running path
to achieve optical acceleration cancellation of the ball. Yet people appear to lack the ability …

Abstract Information specifying the future passing distance of an approaching object is
available (in units of object size) in the ratio of optical displacement velocity and optical …

We make an appeal to bring the theoretical tools of ecological psychology to focus on road-
traffic accidents that result from making left turns. Following a review of previous arrival-time …

In a forced-choice paradigm, human observers' sensitivity to visual information specifying a
moving object's future time of arrival at a designated position in the field of view was …

Films of pigeons flying to a perch were analysed to test a theory of how speed of approach
and timing of foot extension in preparation for landing are visually controlled. Rapid neural …

Deceleration during braking could be controlled by (a) using the time derivative of the
relative rate of optical expansion, relative to a− 0.5 margin value of tau-dot (DN Lee, 1976) …
