LAB EXAM 2 Flashcards
What are the three types of memory?
Sensory memory, Short term memory, and long term memory
What is the difference between sensory memory and short term memory?
With enough attention, you can go from sensory to short term, but unrehearsed information is lost.
What is the MultiStore model?
A model of human memory concerning sensory, short-term, and long-term.
How long is memory stored in each type of memory?
Sensory: 1-3 seconds
Short term: 30ish seconds, 7ish items
Long term: No known time limit/capacity
What is the Levels of Processing Theory?
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
What are the 3 types of processing?
- Shallow processing: (FORM) Just looking at the item, like shape and color
- Intermediate processing: (RHYME) Based on the sound/how it is related to other words
- (CATEGORIES) Processing the information ina meaning and elaborate way i.e. associating it with personal experiences
What is the MultiStore Model Hypothesis?
The longer the encoding time, the better our memory for an item
What is the Levels of Processing Hypothesis?
The deeper the processing, the better the memory for an item
What is psychophysiology?
The branch of psychology that is
concerned with the physiological
bases of psychological processe
Why should we measure physiological responses?
Everything we do/think/feel is neural/biological activity!
What are our dependent measures for Lab 6?
Pulse Rate (PPG), Muscle Activity (EMG), and Galvanic Skin Response (GSR)
What is a PPG?
It’s a photoplethysmogram, and it meassures the changes in reflection of light from the fingertip
What is an EMG?
Electromyogram senses the electrical signals generated by activity of the muscles
What is a GSR?
Measures the changes in the conductivity of the skin
What did each lead do?
The red lead was the positive, the black was the ground (neutral), and the white was negative. EMG
Where did each lead go?
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
Where does the GSR go?
On your index finger
Where does the PPG go?
Ring finger tip
What is Operant Conditioning?
Specific consequences are associated with a voluntary behavior
What was the order of methods for training the rat?
Operant rate, Shaping, Acquisition, Non-contingent reinforcement, extinction
What are binocular disparity?
As an object comes closer to us, the differences in images between our eyes becomes greater
What is convergence?
As an object comes closer our eyes have to come together to stay focused
What is the ponzo illusion?
Slanted lines with smaller lines inside
What is the Constancy Scaling Theory?
perceived size increases or decreases in direct proportion to perceived distance
