Document Summary

Sensation: the process of detecting a stumulus (receptor) Perception: the higher order process of integrating, recognizing and interpreting patterns of sensation. Case example: the man who mistook his wife for a hat. Cortical processing: primary sensory cortex secondary sensory cortex association cortex. Produces an internal representation of the outside world. A perception of reality based on specific receptors ( hardware") Interspecific differences: e. g. snakes can see infrared; insects see ultraviolet. Top-down influence: attention, individual experience, etc. affect perception. E. g. same scene viewed differently by different people with different interests. Light: electromagnetic wave (energy) that can be represented by discrete units/particles of energy called photons. Visible light waves (humans): 380-700 nanometers (billionths of a meter) Intensity brightness e. g. bright red" = our perception of high intensity, 700 nm wavelength light. Iris: contractile tissue it regulates the size of the pupil. Wide pupil more light sensitivity less acuity. Narrow pupil lower light sensitivity higher acuity.
