CLPS Sensation and Perception

Bottom up vs top down processing

Bottom-Up: Sensory receptors → Brain: sensation Top-Down: Brain → experience/expectations to interpret sensory info: perception

Visual transduction

Cones are color sensitive and finer detail. Lots of cones in center of vision:fovea. Rods are more sensitive to motion in the periphery. Can't see color.

Transduction

Conversion of physical signals into neural information. light comes in, hits cones and rods. Sort of middle ground between sensation and perception.

Sensation

Process of detecting, converting and transmitting raw information from external environment to internal representation. Incoming information from physical world that you detect and convert into a. mental representation. Has to code both qualitative and quantitate aspects of what you're seeing.

Perception
