Topic 6 Flashcards
Perception
Processes used to gather and interperet sensory information from the internal and external environment
Sensation
Stimulation of sensory receptors
6 perceptual modalities
Visual Auditory Kinaesthetic Tactual Olfactory Gustatory
Astigmatism
Cornea not symmetrical
Thicker retina leads to…
Blurry vision
Short eyeball leads to…
Farsightedness
Object permanence
The realisation that objects continue to exist when they are no longer in the field of view
A-not-B error
Mistakenly thinking the same object is two different objects if object A is hidden and then revealed
Perceptual constancy (+ age of maturity)
Understanding the physical qualities of an object do not change regardless of what distance or angle the object is viewed from - matures at 11 yrs
Spatial orientation (+ age of maturity)
Ability to recognise an object’s location or orientation in 3D space - matures at 8 yrs
Figure-ground perception (+ age of maturity)
The ability to distinguish and object from its surroundings - matures at 13 yrs
Depth perception (+ age of maturity)
Judgement of distance between an object and self - matures at 12 yrs
Field of vision
The entire space seen without moving the head or eye
Kinesthetic perception
The ability to understand where the body is in space
Kinesthetic acuity (+ age of maturity)
Detecting similarities or differences in body positioning via proprioception - matures at 8 yrs
Kinesthetic memory (+ age of maturity)
Ability to reproduce a movement - matures at 12 yrs
Perceptual integration
The use of multiple senses to gain information from a situation, as well as to plan motor movements
Body awareness (+ age of maturity)
Awareness of body parts by name, function, location, and relationship to each other - matures at 6 yrs
Spatial awareness (+ age of maturity)
Ability to identify location of one’s body in space, relative to environment - matures at 16 months
Directional awareness (+ age of maturity)
Ability to identify laterality of the body and project the body within the various dimensions of external space - matures at 12 years
Vestibular awareness
Necessary for establishment and maintenance of balance
Rhythmic awareness
Creating or maintaining a temporal pattern within a set of movements
Auditory perception (+ age of maturity)
Localisation, discrimination, and figure-ground perception (speech in the presence of noise) of sounds - matures at 13 yrs
Tactile perception (+ importance)
Ability to detect and interperet sensory information cutaneously - necessary for reflexive behaviour
Affordances
Opportunities for action that objects, events, or places in the environment provide
