Study Notes
Sensation vs. Perception
- Sensation involves stimuli detection, while perception is the interpretation of sensory information.
- Just noticeable difference is the smallest detectable change in sensation, recognized 50% of the time.
- Absolute threshold for vision is determined as a candle flame seen at 30 miles away on a clear night.
Sensory Processes
- Transduction is the process of converting physical energy into neural signals.
- Difference threshold refers to the minimum amount needed to perceive a change in stimulus intensity.
- Sensory adaptation is the phenomenon where sensitivity to a stimulus decreases after prolonged exposure.
Visual System
- The primary human sensory system essential for daily functioning is vision.
- Cornea is the transparent outer covering of the eye that bends light rays to aid focus.
- Two types of photoreceptors in the eye are cones (color vision) and rods (light sensitivity).
- Adaptation refers to the lens's ability to change shape for focusing on images on the retina.
Color Vision
- Colors are experienced through three dimensions: hue, saturation, and brightness.
- Opponent-process theory suggests that color perception is controlled by opposing colors' interactions.
- Trichromatic theory posits that there are three types of cones sensitive to blue, red, and green.
Auditory System
- Frequency refers to the number of cycles a sound wave completes in one second, affecting pitch.
- Place theory explains pitch perception based on the location of maximum vibration on the cochlea’s basilar membrane.
- The measurement of sound loudness is quantified in decibels.
Taste and Smell
- Gustation provides five distinct tastes: sweet, sour, salty, bitter, and umami (monosodium glutamate).
- Taste is influenced by temperature, smell, color, and texture.
- Olfactory system processes smell information and connects closely to memory and emotion.
- Olfactory epithelium houses approximately 10 million receptor cells for detecting smells.
Touch and Kinesthetic Senses
- Tactile perception pertains to the sense of touch.
- Somatosensory cortex processes signals for heat and pain.
- Vestibular sense provides information on body position and movement.
Depth Perception
- Depth cues like interposition, linear perspective, and relative size are classified as monocular cues.
- Perceptual constancy allows us to perceive familiar objects as having stable color despite changes in lighting.
- Phi phenomenon offers a cognitive way of perceiving depth from the slightly different images our eyes receive.
Perception Theories
- Gestalt psychology emphasizes the idea that "the whole is more than the sum of its parts" in perception.
- Figure-ground principle explains how we distinguish an object from its background.
- Perceptual set shows how expectations influence our sensory interpretations.
Illusions and Extrasensory Perception
- Illusions represent a false perception of actual stimuli.
- Extrasensory perception refers to the ability to receive information beyond normal sensory processes.
Miscellaneous Facts
- Motion parallax is a perceptual phenomenon experienced when moving through space.
- True or false questions help reinforce key concepts; for example, concepts about thresholds, perceptions, or the sensory systems involve distinguishing facts from misconceptions.
- Waves in the visible spectrum represent the thin electromagnetic waves we can perceive visually.
