Study Notes
Visual and Auditory Perception
- Perceptual organization is the cognitive ability to arrange sensory data in an orderly, not random, way.
- Gestalt psychology emphasizes perceptual organization through procedures of grouping and segregation.
- Factors influencing figure-ground separation include size, contrast, symmetry.
- Gestalt psychology helps understand the difference between sensation and perception, including top-down and bottom-up processing.
- Visual perception uses visible light reflected from objects (photopic, scotopic, mesopic vision).
- Visual acuity (e.g., 20/20 vision) is different from visual perceptual processing.
- Figure-ground differentiation is crucial for visual object recognition (e.g., black letters on white paper).
- Visual object constancy allows recognizing objects from different angles.
Auditory Perception
- Auditory perceptual organization is more complex than visual organization, as simultaneous sounds can mix.
- Difficulty segregating and localizing sounds, compared to visual objects.
- Sound categorization is more challenging due to a greater number of auditory dimensions.
Set and Other Aspects of Perceptual Organization
- Past experiences, expectations, motivations, beliefs, emotions, and culture influence perception (Biggs, 2015).
- Perceptual set is a tendency to view things in a certain way, a top-down processing example.
- Motivation, expectations, culture, emotions, and attitudes are influential factors in our perceptions.
- Example: Motivations can impact how we perceive members of opposing teams as aggressive or weak.
Visual and Auditory Development in Children
- Early (1960s) experiments on monocularly deprived kittens highlighted a critical period for visual development.
- Both eyes need input for full binocular vision development.
- The visual system "hardwires" by 7-9 years.
- Hearing is essential for speech development; a critical period exists for vocal learning.
- Visual and auditory impairments do not significantly affect IQ, but cause unique challenges.
Perception as an Active Process
- Early visual perception is limited, gradual development of perceptual capabilities; Piaget (1953) and Hebb(2012).
- Visual perception starts with colour, focuses on recognizing the distinct parts of an object, and integrates to recognize an object as a whole.
- An active process combining sensory system and brain activity; a constructionist theory.
Development of Visual Perception in Relation to Environment
- Entering a visual environment leads to object impressions and context-specific actions.
- Research on infant perceptions examines how visual perceptions evolve.
- Infants' ability to categorize visual stimuli is associated with environmental requirements.
- Experience plays a key role in visual perception development (Gibson 1979).
- First year of life is marked by a dramatic visual system and brain development.
