Perception of acceleration with short presentation times: Can acceleration be used in interception?

Time-to-Contact Estimation of Accelerated Stimuli Is Based on First-Order Information.

“…For another, the level of sensitivity required of the perceptual system in the detection task is relatively weak compared with the accuracy required in the timing of some interceptive actions that occurs around several milliseconds (e.g., Regan, 1997). Werkhoven et al (1992) suggested that the detection of acceleration evident in psychophysics experiments could be due to processes that compare the velocity of the stimulus at different instants rather than to a visual receptor permitting direct perception of acceleration (see also Brouwer et al, 2002). This suggests that there may be two independent mechanisms that depend on the task requirement: one for verbal-cognitive identification, the other for motor control.…”

“…In the second experiment, we used an indirect interceptive task in which participants intercepted a moving stimulus using a ball 3 Some recent studies have tried to test Chapman's (1968) hypothesis, according to which locomotor displacements required to catch a ball in flight could depend directly on the perception of the acceleration of the ball (e.g., Babler & Dannemiller, 1993;Brouwer et al, 2002;P. McLeod, Reed, & Dienes, 2001;Michaels & Oudejans, 1992;Oudejans, Michaels, Bakker, & Davids, 1999).…”

Optical acceleration cancellation: a viable interception strategy?

“…Parallel to this, the method of information processing is likely to shift from internal models and quasioptimal planning to direct feedback of the sensory signal, i.e., to instantaneous perception-action coupling. For this final phase, OAC/OAF might be candidate strategies; the visual accelerations during this final phase are so high that it is expected that the limited sensitivity of the eye for visual acceleration (Brouwer et al 2002) will not cause a problem. However, discriminating experimentally between strategies close to the moment of interception will not be easy, as their predictions probably will not differ very much.…”

Anticipating the effects of visual gravity during simulated self-motion: estimates of time-to-passage along vertical and horizontal paths

“…Accelerated motion is frequent in Earth gravity (1 g = 9.8 m/s 2 ), but the issue of discriminability of acceleration from visual information is still controversial. Most studies indicate that human and non-human primates can visually detect accelerations, but the discrimination of acceleration is much poorer than that of speed (Orban 2008;Brouwer et al 2002;Werkhoven et al 1992;Snowden and Braddick 1991;Calderone and Kaiser 1989;De Bruyn and Orban 1988). In some self-motion studies, TTP estimation did not seem to take into account the deceleration signal, while the use of acceleration signal appeared to depend on stimuli parameters (Festl et al 2012;Capelli et al 2010;Kaiser and Hecht 1995).…”
