Sensation Vocab Flashcards
Sensation
Receive info from five main senses
Bottom-up processing
Little details to big picture
Perception
Organizing/interpreting sensory info
Top-Down Processing
Big picture to analyzing little details
Absolute Threshold
Minimum amount of change needed to fire
Signal Detection Theory
How/when we detect things (neurons firing, surroundings, you)
Sensory Adaptation
Neurons stop firing for same message
Selective Attention
What we choose to focus on
Vision
Light waves
Trichromatic color theory
Process color with three types of cones (red, green, blue)
Color deficiency
Lack of one of three cone receptors
Opponent-process theory
Process colors with three pairs of receptors (red/green, yellow/blue, black/white)
Hearing
Sound waves
Pitch
High or low based on frequency
Decibles
Loud or soft based on amplitude
Smell and taste
Chemical sense
Touch
Mechanical sense
4 Touch Senses
Pain, warm, cold, pressure
Gate control theory
Pain travels on its own neural pathways
Kinesthetic sense
Sensing body position and movement
Vestibular sense
Sensing body orientation and balance
