Comparing Verbal and Reaching Responses to Visually Perceived Egocentric Distances

Distance estimation in large immersive projection systems, revisited

“…Participants were instructed to point at the target as accurately as possible while performing the side stepping at a reasonable speed to reduce effects of decreased precision caused by changes in the remembered position of the target over time (cf. [19]). Participants received no feedback about their pointing accuracy in order to minimize the effects of perception-action motor recalibration in the response method while assessing distance perception.…”

Human kinematics and event control: on-line movement registration as a means for experimental manipulation

“…Oudejans et al (1996a) found that perceptual judgements of whether a fly ball is catchable were better when participants were allowed to move compared to when they had to make their judgements from a stationary position (as is often done in experimental settings), a finding that was replicated with respect to judging whether a busy street was crossable while walking or while standing still (Oudejans et al, 1996b). Pagano et al (2001) found systematic differences in perceived distance between judgements using verbal responses and using manual reaches. This is related to the current debate in the literature about different functional pathways for the processing of visual information in the central nervous system.…”

“…For example, perceptual judgement studies provide different information to studying perception in action (e.g. Oudejans et al, 1996a;Pagano et al, 2001). Oudejans et al (1996a) found that perceptual judgements of whether a fly ball is catchable were better when participants were allowed to move compared to when they had to make their judgements from a stationary position (as is often done in experimental settings), a finding that was replicated with respect to judging whether a busy street was crossable while walking or while standing still (Oudejans et al, 1996b).…”

On Ecological Conceptualizations of Perceptual Systems and Action Systems

“…Second, we discuss the possibility that functional systems should be understood as softly assembled devices, as several ecological psychologists seem to suggest (see, e.g. Pagano, Grutzmacher, & Jenkins, 2001). We ultimately reject both possibilities, and put forward the view that functional systems are best understood as the animals' powers to achieve functional relations with their environments.…”

“…Bingham, 1988;Kugler & Turvey, 1987;Pagano et al, 2001). The idea is that the anatomical structures of the body have particular dynamic properties.…”
