What occurs anytime that a stimulus activates one of your receptors?

• sensation

• perception

• psychophysics

• sensory adaptoin

What is the difference threshold?

• The minimum difference in stimulation that a person can detect 50 percent of the time
• The maximum difference in stimulation that a person can detect 50 percent of the time
• The average difference in stimulation that a person can detect 50 percent of the time
• The difference in stimulation that a person can detect 100 percent of the time

What is the definition of sensory adaptation?

• The process by which our sensory receptors become less responsive to constant or unchanging stimuli.

• The process by which our sensory receptors become more sensitive to changing stimuli.

• The process by which our sensory receptors become completely unresponsive to any stimuli.

• The process by which our sensory receptors become more responsive to constant or unchanging stimuli.

Which of the following processes has begun as soon as special receptor cells for the senses are activated?
