Visual Perception and Visual Motor Skills Flashcards
Perceptual learning
experience-dependent enhancement of our ability to make sense of what we see, hear, feel, taste, or smell
Visual recognition memory
Ability to discriminate whether a visual stimulus is novel or familiar
Established by 5-7 months
Visual habituation
Once a stimulus is fully encoded, the infant habituates to it and demonstrates decreased attention to the stimulus
Importance of vision is social development
Important for perceiving facial expressions and emotions
Mutual gaze can facilitate attachment
Child engages in social imitation of facial expression
Importance of vision for school
Reading
Copying from board
Writing
Playing
Sports
3 Component model of vision
Visual information processing
Visual integrity
Visual efficiency
What does visual information processing include?
Visual spatial skills (laterality, directionality, spatial relationships)
Visual analysis skills (figure ground, form constancy, visual orientation, visual discrimination, visual closure, visual memory, visualization)
Visual motor skills
Laterality
Understanding left and right
Relates this to own body until 6-7 years
Directionality
Understanding objects’ position in space in relation to self
Other things also have right and left sides
Spatial relationships
Ability to perceive two or more object’s position in space
Improves until approximately 10 years
Figure ground perception
Ability to differentiate an object from the background
Improves between 3-5 years (preschool)
Form constancy
Allows you to understand that a form, shape, or object stays the same even if it changes size, positoin, or is in a different environmnet
Dramatic improvement between 6 and 7 years
Visual orientation
Awareness of the location of objects in the environment and their relationship to one another
Visual discrimination
Ability to detect differences in and ability to classify objects, symbols, or shapes
Visual closure
Allows you to know what an object is even when only partially visible
