a. When sensory information is detected by a sensory receptor, sensation has occurred. TRUE

b. All sensory systems have absolute and difference thresholds. FALSE

Absolute threshold refers to the minimum amount of stimulus energy that must be present for the stimulus to be detected 50% of the time.

c. Sensory receptors are specialized neurons that respond to specific stimuli. TRUE

d. Sensation refers to the way sensory information is organized, interpreted, and consciously experienced. TRUE
