Document Summary
Information: sensing raw data (frequencies of light, intensity of sound, etc. ) we have receptors on our skin as well that feels touches. Sensation doesn"t happen outside of our body, it happens on our body and on our receptors. Perception: interprets the raw data/ sensation, tries to recognize what that is. This happens so fast that we don"t notice the sensation part. Sensation: the process of detecting external events by sense organs and turning those stimuli into neural signals. Perception: involves attending to, organizing, and interpreting stimuli that we sense. Distinct pathways connecting receptors to brain areas develop until the age of 3, so they weren"t always distinct. Babies can interpret language in temporal and occipital. Both receptors and preceptor brain areas are extremely sensitive to change (evolutionarily) Which is why you"re so shocked to see light after coming out of a dark movie theatre. Sensory adaptation: the reduction of activity in sensory receptors with repeated.
