Perception Flashcards
(8 cards)
What is the relationship between sensation and perception?
Sensation is the raw input from the senses; perception is how the brain organizes and interprets that input into meaningful experiences.
What are the perceptual concepts of reality, ambiguity, and illusion?
Reality: What actually exists in the environment.
Ambiguity: When sensory info can be interpreted in more than one way.
Illusion: A false perception that doesn’t match reality.
What role does attention play in perception?
Attention selects which sensory info to focus on, enhancing perception of relevant stimuli and filtering out distractions.
What are preattentive processing and guided search?
Preattentive processing: Detecting basic features (color, shape) instantly without focus.
Guided search: Using features and goals to focus attention during visual search.
What are the Gestalt principles of figure, ground, and closure?
Figure: The object of focus.
Ground: The background.
Closure: Filling in gaps to see a whole (e.g., seeing a full circle when parts are missing).
What are the principles of perceptual grouping?
Gestalt laws like similarity, proximity, continuity, and common fate explain how we group elements into unified wholes.
What are motion and depth perception?
Motion perception: Detects movement through changes over time.
Depth perception: Uses cues (binocular & monocular) to perceive 3D space and distance.
What are identification and recognition in perception?
Identification: Assigning meaning to a perceived object.
Recognition: Matching perception with memory to know what something is.
