Study Notes
Sensation and Perception Key Concepts
-
Sensation vs. Perception: Sensation is the detection of stimuli; perception is the interpretation of those stimuli (e.g., recognizing an alarm sound).
-
Pupil Size: Pupils are smallest on sunny days due to intense light exposure.
-
Sensory Modalities: Different senses like vision and hearing function via distinct sensory modalities.
-
Signal Detection Theory: A false alarm occurs when one anticipates a stimulus that isn’t present (e.g., turning off radio thinking phone is ringing).
Psychophysics and Sensory Receptors
-
Psychophysics: The study of how physical stimuli influence sensory experience and perception.
-
Temperature Sensation: Specialized sensory receptors in the skin, called free nerve endings, report temperature changes.
Receptive Fields and Pain Detection
-
Receptive Field: The area where stimuli can influence the activity of sensory cells.
-
Nociceptors: These sensory receptors are primarily responsible for sensing pain.
Visual System Mechanics
-
Lens Focusing: The lens of the eye focuses light onto the retina for proper visual perception.
-
Photoreceptors: Cones are responsible for detecting color during daylight; rods are crucial for seeing in low light conditions.
-
Blind Spots: Occur due to the absence of photoreceptors on the optic disc.
Depth Perception
-
Binocular Cues: Depth perception that relies on visual information from both eyes.
-
Monocular Size Cue: Reveals depth by size perception; an object appears smaller when farther away (e.g., a distant friend looks small).
Color Vision Theories
- Opponent-Process Theory: Proposes color perception is based on opposing color pairs.
Size Constancy
- Size Constancy: The ability to perceive an object as maintaining the same size despite changing distances.
Gestalt Psychology
- Gestalt Principles: Focus on how visual organization and perception of images occur; related topics often discussed in vision-related psychology lectures.
