Document Summary
Principle of transformation: states that stimuli and responses created by stimuli are transformed, or changed, between the environmental stimulus, and perception. Principle of representation: everything a person perceives is based not on direct contact with stimuli, but on representations of stimuli that are formed on the receptors and on activity in the persons nervous system. Tree in environment is transformed into image on the retina, and this image represents the tree in the persons eyes. Visual receptors transform light energy into visual pigment: a light sensitive chemical that reacts to light. Transduction: transformation of one form of energy to another form of energy, network of neurons: Changes/processes the signals as they are transmitted. Primary receiving area: in the cerebral cortex, electrical signals from each sense arrive here. Frontal lobe: receives signals from all the senses. Visual form agnosia: inability to recognize objects, caused by brain tumour in mr. p.
