Question 1

Sensation vs. Peception

Answer 1

Sensation - physical processes where our sensory organs (like tasing & hearing are involved)

Perception: psychological processes where we remember to identify a gas leak or when a song reminds you of something

Question 2

Transduction

Answer 2

convert physical energy like light into electrical energy so our brain can perceive around us

Question 3

Basic Principles of Sensation and Perception

Answer 3

1: Absolute Thresh-hold - requires a minimal sense of stimulation to be able to identify it

2: ability to detect two stimuli of different intensities; bigger stimuli require larger differences to be noticed

3: When an experience stimuli doesn’t change, we stop paying attention to it (ex. Top-down processing - we’ll skip over the second “the” because we are used to it)
