Chapter 2 Flashcards
Independent Variable
The aspect of an experiment that is made to systematically vary across the different conditions in the experiment.
What is manipulated in an experiment
Dependent Variable
The aspect of an experiment that is allowed to vary freely to see if it is affected by changes in the independent variable.
What we measure in an experiment
Stimulus
Any event that can potentially influence behavior
Food, loud music, high grade on an exam
Response
A particular instance of behavior
How you react to your neighbor playing loud music (bang on the wall), smile when you get a good grade
Behavior v.s. Response
-behavior of pressing a lever, each individual time the lever is pressed is the response
Overt Behavior
Behavior that can potentially be observed by an individual other than the one performing the behavior.
Behavior that could be publicly observed if others were present
-a person’s response of saying hello and a rats response of pressing a lever
Behaviorists emphasize the study of overt (observable) behavior
Covert Behavior
Behavior that can be perceived only by the person performing the behavior
Behavior that is subjectively perceived and is not publicly observable
-dreaming, thinking about your next chess move, visualizing how your date will go this weekend, and feeling anxious
Appetitive Stimulus
An event that an organism will seek out
-food (seek out when hungry), water (when thirsty)
Aversive Stimulus
An event that an organism will avoid
-electric shock, extreme heat
Deprivation
The prolonged absence of an event
Satiation
The prolonged exposure to or consumption of an event
Repetition causes a word or phrase to temporarily lose meaning for the listener
Perceived words as meaningless sounds.
Cessation of a desire or need by satisfaction of that desire or need.
-feeling full
Contiguity
“Closeness or nearness”
Temporal Contiguity
The extent to which events occur close together in time
- thunder and lightening
- rat will learn to press the bar sooner if given food immediately, kid will learn to cry to get candy if you give it to them to make them calm down
Spatial Contiguity
The extent to which events are situated close to each other in space
It’s easier for a rat to learn to press the bar if food dispenser is near the bar
Learning knock is someone at the door sooner than learning door bell means the same thing, because the knock is closer to the actual door
Contingency
A predictive (or functional) relationship between two events, such that the occurrence of one event predicts the probable occurrence of another
If a child receives a balloon every time they go to the dentist, the contingency exists between the balloon and visiting the dentist
Recording Methods:
Rate of Response
The frequency with which a response occurs in a certain period of time.
Number of lever presses PER HOUR
