Document Summary
= physical sensory receive represents stimuli (sensory receptors to brain) = interpret sensory input from experience (memory first then sensory receptors) Ex: remember fire = pain, then you touch fire. Process: receive stimuli transform into neural impulses information to brain. Transduction = conversion of one energy to another (electric signal) Signal detection theory whether or not we detect stimuli especially amidst background noise. Below threshold for being able to consciously detect stimuli. Absolute threshold minimum is detected 50% of time. Subliminal input below absolute threshold (of awareness) Priming (often unconscious) prime person to react to certain stimuli. Difference threshold minimum difference for person to detect difference (50% of. Weber"s law principle that for 2 stimuli to be seen at once, they must differ by a constant minimum percentage and not constant amount. Sensory adaption diminish sensitivity as a consequence of constant stimulation, reduce background stuff to focus, influences emotions and how world is seen time)
