Day 32

Learning Targets:  

• Students will be able to describe the structure and function of the 5 basic senses and how these processes influence human behavior.
• Students will be able to understand the impact of perception on the influence of behavior.

Opener:  What is the absolute threshold for sounds?

Activity #1:  Sensation vs Perception 

Difference Threshold - The minimum amount of difference that can be detected between stimuli

Signal Detection Theory - Theory that states that other variables in your setting influence how we process signal stimuli

The Ear

Pitch - The variance in sound waves that determines how high or low the sound. 

Loudness - measured in decibels, this is the amplitude of the soundwave

Auditory Nerve - Sends neural impulses to the brain based upon the movement and vibrations of fluids in the cochlea.
