AP Psych Unit 3 Test Part 5 - Color Vision and Audition

How do sensory receptor pairs work?

Some neurons are turned on by red and off by green, etc.

Frequency

Number of wavelengths in a given time

Opponent-Process Theory

Sensory receptors in the retina come in pairs

What are the sensory receptor pairs in the retina?

Red/green, yellow/blue, black/white

What is the present solution for color vision?

There are 2 stages - trichromatic theory happens first, then signals are processed by opponent-process cells on their way to the visual cortex

Light/dark adaptation

Pupils dilating

What can we hear?

Pitches corresponding to the human voice, volume, variations

What is the measurement for pitches corresponding with the human voice?

20Hz - 20kHz

What is the stimulus input for hearing?

Sound waves

What are sound waves?

Jostling molecules in the air

1 Hz

1 wave cycle per second

What does frequency determine?

Pitch

Amplitude

Height of a wave

What does amplitude determine?

Volume
