Question 12

Muller-Lyer illusion

Answer 12

The illusion that 2 straight lines are different length by using other lines to manipulate our perception

Question 13

Absolute threshold

Answer 13

Question 14

Just noticeable difference

Answer 14

The smallest difference detectable 50% of the time

Question 15

Subliminal perception

Answer 15

The belief that we can do certain things and the info gets to our unconscious

Answer 20

We are constantly running into sensory stimuli, so rather than being overwhelmed with information this allows the brain to filter out unchanging things (to conserve energy)

Question 21

Scarecrow example of habituation

Answer 21

A farmer puts out a scarecrow, crows leave – after a short while the crows get used to the unmoving/unchanging scarecrow, crows come back
