The Basics We do not actually experience the world directly, but  instead we experience it through a series of “filters” we  call senses.  The study of these sense and their effect on our behavior  is called  sensory psychology .

Sensation Sensation:  The process by which a stimulated receptor  (eyes, ears…) creates a pattern of neural messages that  represent the stimulus in the brain, giving rise to our  initial experience of the stimulus.

Our Senses You will notice that all of our sense organs are very  much alike.  They all transform physical stimulation (such as light  waves or sound waves) into the neural impulses what  give us sensations (such as light and dark).

Perception Perception:  A mental process that elaborates  and assigns meaning to the incoming sensory  patterns. Perception creates an interpretation of sensation. Do you see faces or vases?

Sensation and Perception Perception is essentially an interpretation and  elaboration of sensation. Therefore, sensation refers  to the initial steps in the processing of a stimulus. These pictures should look similar

Big Idea Although it seems the brain interacts  directly with the outside world, it does  not. The brain senses the world indirectly  because the sense organs convert  stimulation into the language of the  nervous system:  neural messages . In short, the brain never receives  stimulation directly from the outside world.

Transduction: Changing Stimulus to Sensation In all the sense organs, it is  the job of sensory receptors  to convert incoming stimuli  information into  electrochemical signals— neural activity. Transduction:  The sensory  process that converts energy,  such as light or sound waves,  into the form of neural  messages. Transduction with Hearing
