Module 1.6D (Body Senses)

Front

What is the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment?

Back

Sensation

Front

What is the process by which our brain organizes and interprets information, enabling us to recognize meaningful objects and events?

Back

Perception

Front

What term refers to analysis that begins with the sensory receptors and works up to the brain's integration of sensory information?

Back

Bottom-Up Processing

Front

What term refers to information processing guided by higher-level mental processes, as when we construct perceptions and expectations?

Back

Top-Down Processing

Front

What is the focusing of conscious awareness on a particular stimulus?

Back

Selective Attention

Front

What term refers to the minimum stimulus energy needed to detect a particular stimulus 50 percent of the time?

Back

Absolute Threshold

Front

What term refers to the minimum difference between two stimuli required for detection 50% of the time?

Back

Difference Threshold (JND)

Front

What principle states that to be perceived as different, two stimuli must differ by a constant minimum percentage rather than a constant amount?

Back

Weber's Law

Front

Conversion of one form of energy into another (sights, sounds & smells into neural impulses)

Back

Transduction

Front

Diminished sensitivity as a consequence of constant stimulation. (i.e. hear the loud AC unit in your room because you're used to it and are focusing on other newer stimuli)

Back

Sensory adaptation
