Document Summary
2 why study s & p: sensation. What takes place from the sensory receptors to the primary projection areas: perception. Everything beyond that: importance of the process. We construct the world around us and therefore we bias our own perceptions. Detecting a stimulus requires a judgment about its presence or absence: 2 processes work at detection tasks. A decision process will reflect personal bias: experimental procedure, 2 kinds of errors & 2 kinds of cr. Hit & correct negative (response: factors affecting response bias. Signal detection theory (reference figure in other document) The eye and light: path of light. Cornea transparent membrane that protects eye. Pupil (is clear) size changes to allow more or less light. Lens takes in light, bends the light rays to focus them: ciliary muscles. Retina (three layer structure, covers inside surface of your eye) ganglion cells, cones and rods. The retina: cones (responsible for light vision, not sensitive to light)
