Can I reach that? Blind reaching as an accurate measure of estimated reachable distance
Multisensory integration induces body ownership of a handtool, but not any handtool
Art and Aging: Digital Projects for Individuals With Dementia
In action teaching, assignments are created that simultaneously benefit students and society by directly connecting classroom material to a community intervention. We designed an entire course rooted in the principles of action teaching in which students facilitated the positive effects of art, nature, and music on the well-being of individuals diagnosed with dementia. Groups of three students worked with a local elderly couple, one member of who…
Depth Perception and the Perception of Events
The study of visual depth perception is one of the oldest domains of inquiry in Psychology. A review is provided of the known depth cues, which are the informational sources for depth perception, and the means by which these cues are combined. Distance, size, and slant perception are surveyed. Event perception is a newer field of study. A review is provided of how people perceptually organize and interpret motions and their role in guiding behavi…
A new mode of fear expression: Perceptual bias in height fear
Emotion and psychopathology researchers have described the fear response as consisting of four main components--subjective affect, physiology, cognition, and behavior. The current study provides evidence for an additional component in the domain of height fear (perception) and shows that it is distinct from measures of cognitive processing. Individuals High (N = 35) and Low (N = 36) in acrophobic symptoms looked over a two-story balcony ledge and…
Social support and the perception of geographical slant
Embodied Perception and the Economy of Action
Perception informs people about the opportunities for action and their associated costs. To this end, explicit awareness of spatial layout varies not only with relevant optical and ocular-motor variables, but also as a function of the costs associated with performing intended actions. Although explicit awareness is mutable in this respect, visually guided actions directed at the immediate environment are not. When the metabolic costs associated w…
The Role of Effort in Perceiving Distance
Berkeley proposed that space is perceived in terms of effort. Consistent with his proposal, the present studies show that perceived egocentric distance increases when people are encumbered by wearing a heavy backpack or have completed a visual-motor adaptation that reduces the anticipated optic flow coinciding with walking effort. In accord with Berkeley's proposal and Gibson's theory of affordances, these studies show that the perception of spat…
Infants' encoding of kinetic displays varying in relative coherence
Development of intuitive theories of motion: Curvilinear motion in the absence of external forces
College students and children between the ages of 4 and 12 were asked to draw the path a ball would take upon exiting a curved tube. As in previous studies, many subjects erroneously predicted curvilinear paths. However, a clear U-shaped curve was evident in the data: Preschoolers and kindergartners performed as well as college students, whereas school-aged children were more likely to make erroneous predictions. A second study suggested that the…
