Sensation & Perception

the effect of prior experience and current expectations on perception

diminished sensitivity to an unchanging stimulus

the minimum amount of stimulation needed to detect a particular stimulus (50% of time)

process of analysis that begins with sensory receptors

presented below one's absolute threshold for awareness

the process of receiving and representing stimulus energies through the nervous system

the minimum amount of change needed to detect that two stimuli are not the same

process by which our sensory systems convert stimulus energies into neural messages

ability to pay attention to only one voice at a time

the process by which we select, organize, and interpret sensory information in order to recognize objects and events
