What is sensation?

• Organizing and interpreting information

• A process by which sensory receptors and nervous system receive and represent stimulus energy

• Amygdala

• Psychology

What is bottom-up processing?

• Grouping

• Top-down processing

• Analysis that begins with the sense receptors and works up to the brain's integration of sensory information

• Hypothalamus

What is top-down processing?

• Information processing guided by higher level mental processes

• analysis that begins with the sense receptors and works up to the brain’s integration of sensory information

• Sensation Threshold

• Amygdala

What is the Absolute Threshold?

• minimum stimulation needed to detect a particular stimulus at least 100% of the time

• Amygdala

• Maximum stimulation needed to detect a particular stimulus at least 50% of the time

• minimum stimulation needed to detect a particular stimulus at least 50% of the time

What is Difference Threshold?

• Amygdala

• Mars

• minimum difference between two stimuli required for detection 50% of the time

• Psychology

What is Weber’s Law?

• the threshold for detecting differences is a constant proportion to the size of the original stimulus (approx. 10%)

• minimum difference between two stimuli required for detection 50% of the time

• minimum stimulation needed to detect a particular stimulus at least 50% of the time

• Australia

What is Subliminal?

• When stimuli are below one’s absolute threshold for conscious awareness

• When stimuli are above one’s absolute threshold for conscious awareness

• Europe

• South America

What is Signal Detection Theory

• Frogs

• minimum difference between two stimuli required for detection 50% of the time

• predicts how and when we detect the presence of a faint stimulus (signal) amid background stimulation (noise)

• minimum stimulation needed to detect a particular stimulus at least 50% of the time

What is Transduction?

• Narcissism

• Depression

• conversion of one form of energy to another.

• Generalized Anxiety Disorder

What is Wavelength?

• ABCDEFGHIJKLMNOPQRSTUVWXYZ

• the distance from the peak of one wave to the peak of the next

• Sound Frequencies

• Light Brightness
