hree fundamental elements of the instrumental conditioning paradigm
(1) the instrumental response
(2) the reinforcer or goal event
(3) the relation between the instrumental response and the goal event
Instrumental behavior:
Behavior that occurs because it was previously effective in producing certain consequences
consequences of an action can determine whether
you make that response again
factors responsible for goal-directed behavior are difficult to isolate without:
experimental manipulation
Laboratory and theoretical analyses of instrumental conditioning began in earnest with the work of the American psychologist
E. L. Thorndike.
Thorndike’s original intent was to study
animal intelligence
Thorndike devised a series of __ for his experiments
puzzle boxes
Thorndike’s training procedure consisted of:
placing a hungry animal (often a young cat) in the puzzle box with some food left outside in plain view of the animal
The task for the animal was to learn how to get out of the box and get the food.
Thorndike’s careful empirical approach was a significant advance in
the study of animal intelligence
to Thorndike many aspects of behavior seemed
rather unintelligent
Thorndike interpreted the results of his studies as
Reflecting the learning of a new S–R association
Thorndike formulated the
law of effect.
The law of effect states that:
if a response R in the presence of a stimulus S is followed by a satisfying event, the association between the stimulus S and the response R becomes strengthenedIf the response is followed by an annoying event, the S–R association is weakened
according to the law of effect, what is learned is:
an association between the response and the stimuli present at the time of the response.
the consequence of the response is
not one of the elements in the association
The satisfying or annoying consequence simply serves to:
strengthen or weaken the associa- tion between the preceding stimulus and response.
Thorndike’s law of effect involves:
S–R learning
Once learned, habitual responses occur because:
they are triggered by an antecedent stimulus and not because they result in a desired consequence
Discrete-trial procedures are similar to the method Thorndike used in that
each training trial begins with putting the animal in the apparatus and ends with removal of the animal after the instrumental response has been performed.
Behavior in a runway can be quantified by measuring:
RUNNING SPEED: how fast the animal gets from the start box to the goal box.
running spead typically increases with:
repeated training trials
Another common measure of behavior in runways is
response latency
latency:
the time it takes the animal to leave the start box and begin running down the alley.
Typically, latencies become __ as training progresses
shorter
T maze consists of:
a start box and alleys arranged in the shape of a T.A goal box is located at the end of each arm of the T
Because the T maze has two choice arms, it can be used to :
study more complex questions
free-operant procedures allow
the animal to repeat the instrumental response without constraint over and over again without being taken out of the apparatus until the end of an experimental session.
the free-operant method was invented by
B. F. Skinner (1938) to study behavior in a more continuous manner than is possible with mazes.
Skinner (Figure 5.4) was interested in analyzing in the laboratory a form of behav- ior that would be representative of
all naturally occurring ongoing activity
Skinner recognized that before behaviour can be experimentally annalyzed:
a measureable unit of behavior must be defines
Skinner proposed the concept of
the operant as a way of dividing behavior into meaningful measurable units.
operant response is defined in terms of:
the effect that the behaviour has on the environment
Activities that have the same environmental effect are considered to be:
instances of the same operant response
Behavior is not defined in terms of particular muscle movements but in terms of
how the behavior operates on the environment.
any response that is required to produce a desired consequence is:
an instrumental response because it is “instrumental” in producing a particular outcome.
food-delivery device is called:
the food magazine.
After enough pairings of the sound of the food magazine with food delivery, the sound elicits
a classically conditioned approach response:
preliminary phase of conditioning is called
magazine training.
