ACVREP O&M Exam Study ACTUAL UPDATED QUESTIONS AND CORRECT
ANSWERS
Affordance To gauge the difficulty of an environment by its features— is a hill too steep, gravel
too rough to cross the area
Environmental flow Perception while moving through an area
sensory substitution A process by which information from a damaged sensory channel is replaced by
information entering via other sensory channels.
perceptual learning learning to recognize a particular stimulus.
Unskilled perceptual learning Must concentrate to focus, notice both relevant and irrelevant, near features only
Skilled perceptual learning Becomes more automatic, can multitask, focus on relevant features, able to focus
on distant features
, motor learning Acquisition of patterns of motor control, through practice and experience,
leading to a relatively permanent change in the capacity to produce skilled
movements.
Perceptual-motor coordination Coordinating motor actions with perceptions of thing in the environment —
ascending stairs
procedural knowledge Knowledge of how to do something, such as riding a bike, finding a curb
Episodic knowledge memory for places or events, episodes of experience
Conceptual/Semantic Knowledge Knowledge of patterns. Provides the ability to deal with new situations without
starting from scratch—street-curb-grass-sidewalk-grass relationships, house/office
numbering patterns, etc
Inter-sensory integration Dominance model, equal-weighting model, probabilistic model
Perceptual Errors Localization error & detection error
Localization errors Inability to locate something relative to oneself
Main Processes for crossing a street Alignment, initiating crossing, maintaining a straight heading
path integration Using information about self-movement & things encountered on the way to keep
to your route
Real & imagined spatial frameworks Mental mapping
Allocentric frame of reference Relating the location of objects/places to one another
topocentric information Information about the locations of landmarks/features
Polarcentric information Using cardinal directions
Cartographic information Locations of places/features as they relate to a pattern such as a grid, numbering,
labelling, etc
