Document Summary
Psy 201: the eye, visual pathways, coding of contrast and contour. Short reading (pdf posted on bb: generalizations about processing in the visual system, feature detection, functional specialization. Everything you do depends on sensory/perceptual processing (e. g. , walking, obtaining food, interacting socially). Kinesthesis (limb position and movement), temperature, and pain. [touch, temperature, and pain senses together are referred to as. *sensation : initial coding of messages from the senses. *continuous process : can think of sensation and perception as the transformation of. React directly to stimulation from the environment. *transduction : the conversion of energy from a physical stimulus (e. g. , light) to neural. *sensory neurons : carry neural impulses from the receptor to the central nervous. *sensory areas : sensory neurons and pathways lead to specific sensory areas in the cortex. Sensory areas - e. g. , in the monkey. Visual sensory areas - in the human and monkey. *coding : representation of the stimulus in the pattern of action potentials.
