The name of the Unit that we are currently in is called

• Biology and Behavior

• Sensation and Perception

• Neurons and Brains

• Stimulation and Response

Sensation is a term referring to how

• our minds organize and interpret information and make sense of sensory stimuli

• neurons in our body convert outside stimuli into messages our brain can understand

Perception, on the other hand, is about

• how we take those neuron messages from the outside, and make sense of them in our mind.

• how those signals travel along the axon of a neuron and promote neurotransmission

One of the basic principles of Sensation and Perception is that of the Absolute threshold, which is the minimum level a stimulus needs to be in order for you to _____

• just barely notice it

• notice that it has changed

• not sense it anymore

• become adapted to it

For example: If a candle flame from 30 miles away is at the ABSOLUTE THRESHHOLD for your vision, that would mean if you took a single step backwards, the light will ________

• disappear from your sense of vision.

• get dimmer but still visible

• change color

• convert to sound and your ears will begin "seeing"

Absolute threshold levels are the same across all species and animals

• True

• False

The "difference threshold" is the point at which we become aware when

• a stimulus has changed

• a stimulus has disappeared

• a stimulus becomes converted to a neural message

For example, you are taking a long hot shower, but eventually it begins to "run out" of hot and the water slowly begins to cool. The point when you become AWARE that it is no longer hot is the point at which the stimulation has crossed your....

• Just Noticeable Difference Threshold

• Absolute Threshold

• Submilinal Threshold

• Difference Threshold

You go to a movie theater on a sunny day. As soon as you walk in the dark theater, it is very difficult to see. However, after a few moments your eyes adjust to the darkness and you can see a little bit better. This is an example of

• Sensory Adaptation

• Submliminal Messaging

• Absolute Thresholds

• Difference Thresholds

Sensory adaptation is the idea that we become less sensitive to a(n) ______ stimulus over time.

• Unchanging

• constant

• intermittent

• painful
