Document Summary

Sensation you are unaware of what is happening; while perception you are. Transduction: the process by which sensory receptors convert energy into neural impulses (action potential) Sensory receptors detect and respond to various stimuli (modality specific) Stimuli must go to specific areas in the brain and receptors will only respond to its stimuli. Ana: codes for quality of energy (what kind where is it stimulated) Tc: neural code--action potential (speed/intensity how fast neurons are firing) The difference b/w not being able to perceive a stimulus and being able to precive it. Min. amount of energy needed for receptors to detect stiumuli; thus, detecting happens 50% of the time. To precive as different two stimuli must differ by a constant min. percetange: light intensity 8 , weight 2, tone frequency 0. 3 % You will notice the difference in a weight/light intensity/tone.
