    Study Notes

    Color Vision Theories

    • Opponent-process theory explains color vision through opposing retinal processes (red-green, yellow-blue, white-black).
    • For accuracy, certain cells are excited by one color and suppressed by its opposite.

    Visual and Auditory Processing

    • The optic nerve transmits visual information from the eye to the brain.
    • Parallel processing allows simultaneous handling of various information aspects, crucial for visual tasks.
    • Place theory connects perceived pitch to stimulation location on the cochlea’s membrane.

    Sensory Perception

    • Perception organizes and interprets sensory data, creating understanding of our environment.
    • Perceptual adaptation is the adjustment to visual changes, whether shifts or inversions.
    • Perceptual constancy allows recognition of objects as consistent despite changes in lighting or image.

    Psychological Influences

    • Perceptual set indicates a tendency to interpret stimuli in a certain way based on experiences.
    • Priming activates specific associations, influencing perception and memory subconsciously.
    • Psychophysics examines the relationship between stimulus characteristics and our psychological experiences.

    Eye Structure and Function

    • The pupil is the adjustable opening that allows light entry into the eye.
    • The retina is the inner eye layer containing receptors crucial for processing visual data.
    • Rods detect black, white, and gray, enabling vision in low-light conditions.

    Depth and Spatial Awareness

    • Retinal disparity helps perceive depth by comparing images from both eyes.
    • Selective attention focuses awareness on specific stimuli amidst distractions.

    Hearing and Sensation

    • Sensorineural hearing loss results from damage to the cochlea's receptor cells or auditory pathways.
    • Sensory adaptation is the decreased sensitivity resulting from constant stimuli exposure.
    • Sensory interaction highlights how one sense can influence the perceptions of another.

    Detection and Processing

    • Signal detection theory addresses how stimuli detection is influenced by experience and psychological factors.
    • Subliminal refers to stimuli presented below conscious awareness.
    • Top-down processing uses prior knowledge and expectations for interpreting sensory information.

    Energy Transformation

    • Transduction encompasses the conversion of different energy forms into neural signals interpreted by the brain.

    Balance and Movement Senses

    • Vestibular sense relates to body movement awareness and balance, crucial for spatial orientation.
