LAB EXAM 2

Question 1

What are the three types of memory?

Answer 1

Sensory memory, Short term memory, and long term memory

Question 2

What is the difference between sensory memory and short term memory?

Answer 2

With enough attention, you can go from sensory to short term, but unrehearsed information is lost.

Question 3

What is the MultiStore model?

Answer 3

A model of human memory concerning sensory, short-term, and long-term.

Question 4

How long is memory stored in each type of memory?

Answer 4

Sensory: 1-3 seconds
Short term: 30ish seconds, 7ish items
Long term: No known time limit/capacity

Question 5

What is the Levels of Processing Theory?

Answer 5

A cognitive theory of memory by Craik and Lockhart, suggests that the depth at which information is processed during encoding influences how well it is remembere later

Question 6

What are the 3 types of processing?

Answer 6

1. Shallow processing: (FORM) Just looking at the item, like shape and color
2. Intermediate processing: (RHYME) Based on the sound/how it is related to other words
3. (CATEGORIES) Processing the information ina meaning and elaborate way i.e. associating it with personal experiences

Question 7

What is the MultiStore Model Hypothesis?

Answer 7

The longer the encoding time, the better our memory for an item

Question 8

What is the Levels of Processing Hypothesis?

Answer 8

The deeper the processing, the better the memory for an item

Question 9

What is psychophysiology?

Answer 9

The branch of psychology that is
concerned with the physiological
bases of psychological processe

Question 10

Why should we measure physiological responses?

Answer 10

Everything we do/think/feel is neural/biological activity!

Question 11

What are our dependent measures for Lab 6?

Answer 11

Pulse Rate (PPG), Muscle Activity (EMG), and Galvanic Skin Response (GSR)

Question 12

What is a PPG?

Answer 12

It’s a photoplethysmogram, and it meassures the changes in reflection of light from the fingertip

Question 13

What is an EMG?

Answer 13

Electromyogram senses the electrical signals generated by activity of the muscles

Question 14

What is a GSR?

Answer 14

Measures the changes in the conductivity of the skin

Question 15

What did each lead do?

Answer 15

The red lead was the positive, the black was the ground (neutral), and the white was negative. EMG

Question 16

Where did each lead go?

Answer 16

The white lead goes near the inside of your elbow, the red lead goes on your wrist by your thumb, and the black goes on the other side of your wrist

Question 17

Where does the GSR go?

Answer 17

On your index finger

Question 18

Where does the PPG go?

Answer 18

Ring finger tip

Question 19

What is Operant Conditioning?

Answer 19

Specific consequences are associated with a voluntary behavior

Question 20

What was the order of methods for training the rat?

Answer 20

Operant rate, Shaping, Acquisition, Non-contingent reinforcement, extinction

Question 21

What are binocular disparity?

Answer 21

As an object comes closer to us, the differences in images between our eyes becomes greater

Question 22

What is convergence?

Answer 22

As an object comes closer our eyes have to come together to stay focused

Question 23

What is the ponzo illusion?

Answer 23

Slanted lines with smaller lines inside

Question 24

What is the Constancy Scaling Theory?

Answer 24

perceived size increases or decreases in direct proportion to perceived distance
