Quiz 1 (Psych 049)

Motion parallax and Linear perspective 

Two prominent visual distortions are:

• Blind spot and Parallax error

• Motion parallax and Linear perspective 

• Crossing over and sensory threshold

• Motion parallax and Linear perspective 

True

T/F: According to the sensory code the number of action potentials increases with stimulus intensity

remains the same

Size constancy is a visual perception where the size of the object

• Distorts

• Becomes smaller

• Remains the same 

• Becomes larger

absolute threshold

During an experiment Psychologists presented participants with sounds that varied from 5 decibels to 25 decibels. They found that when the sound was 15 decibels participants detected it 50% of the time. This detection metric is called

• absolute threshold

• just noticeable difference 

• detection threshold

Yes

Sensory adaption occurs when there is no change in stimulus

• No

• Yes

rod, cone

The following is a type of photoreceptor

• nociceptor

• rod

• cochlea

• cone

To increase the dynamic range of the sensory system

Why are there sensory receptors with different thresholds?

• It is an artifact of the sensory system

• To decrease the dynamic range of the sensory system.

• To increase the dynamic range of the sensory system
