- Operant Cognitive Approaches
2OPERANT CONDITIONING
- Operant conditioning
- Also called _________________________________
- Kind of learning in which an animal or human
performs some behavior - Following consequences (__________________________
________) increases or decreases the chance that
an animal or human will again perform that same
behavior
3OPERANT CONDITIONING (CONTD)
- Thorndikes law of effect
- behaviors followed by _____________ consequences
are strengthened - behaviors followed by _______________
consequences are weakened - Skinners operant conditioning
- Operant response can be modified by its
consequences and is a meaningful, easily measured
unit of ongoing behavior - Focuses on how consequences (rewards or
punishments) affect behaviors - 1920s and 1930s discovery of two general
principles - Pavlovs classical conditioning
- Skinners operant conditioning

11OPERANT CONDITIONING (CONTD)
- Examples of operant conditioning
- Toilet training
- target behavior
- preparation
- reinforcers
- shaping
- Food refusal
- target behavior
- preparation
- reinforcers
- shaping
12OPERANT CONDITIONING (CONTD)
- Operant versus classical conditioning
- Operant conditioning
- goal _________________________________________
- voluntary response must perform voluntary
response before getting a reward - emitted response animals or humans are shaped to
emit the desired responses
13OPERANT CONDITIONING (CONTD)
- Operant versus classical conditioning
- Operant conditioning
- contingent on behavior __________________________
__________________________________________________
____ - reinforcer must occur _______________the desired
response - consequences animals or humans learn that
performing or emitting some behavior is followed
by a consequence (reward or punishment)
14OPERANT CONDITIONING (CONTD)
- Operant versus classical conditioning
- Classical conditioning
- goal create a new response to a neutral stimulus
- involuntary response physiological reflexes
(salivation, eye blink) - elicited response unconditioned stimulus
triggers or elicits an involuntary reflex
response, salivation, which is called the
unconditioned response
15OPERANT CONDITIONING (CONTD)
- Operant versus classical conditioning
- Classical conditioning
- conditioned response neutral stimulus becomes
the conditioned stimulus if it occurs before the
conditioned response - expectancy animals and humans learn a
predictable relationship between, or develop an
expectancy about, the neutral and unconditioned
stimuli - classical conditioning leads to learning a
predictable relationship between stimuli
16REINFORCERS
- Consequences
- __________________________________________________
___________________________________ - Reinforcement
- __________________________________________________

____________________________________________ - Punishment

____________________________________________
17REINFORCERS (CONTD)
- Reinforcement
- Positive reinforcement
- refers to the presentation of a stimulus that
____________ the probability a behavior will
occur again - Negative reinforcement
- refers to an _____________ whose
__________________the likelihood that the
preceding response will occur again
18REINFORCERS (CONTD)
- Reinforcers
- Primary reinforcers
- stimulus such as food, water, or sex innately
satisfying and requires __________________________
__________________________________________________
__ - Secondary reinforcers
- stimulus that has acquired its reinforcing power
through experience secondary reinforcers are
learned, such as by being paired with primary
reinforcers or other secondary reinforcers
19REINFORCERS (CONTD)
- Punishment
- Positive punishment
- __________________________________________________
__________________________________ - Negative punishment
- __________________________________________
- noncompliance refers to a child refusing to obey
a command/request given by a parent or caregiver - time-out removes reinforcing stimuli after an
undesirable response - removal decreases the chances that the undesired
response will recur
20SCHEDULES OF REINFORCEMENT
- Skinners contributions
- Schedule of reinforcement
- refers to a program or rule that determines
_______ and _______ the occurrence of a response
will be followed by a reinforcer - Continuous reinforcement
- ______________________ results in delivery of the
reinforcer - Partial reinforcement
- refers to a situation in which responding is
reinforced only __________________________________
____________
21SCHEDULES OF REINFORCEMENT (CONTD)
- Partial reinforcement schedules
-
- Fixed-ratio schedule
- a reinforcer occurs only after a
________________of responses are made by the
subject - Fixed-interval schedule
- a reinforcer occurs after the ___________that
occurs after a __________________of time
22SCHEDULES OF REINFORCEMENT (CONTD)
- Partial reinforcement schedules
-
- Variable-ratio schedule
- a reinforcer is delivered after an
_______________of correct responses has occurred - Variable-interval schedule
- reinforcer occurs after the ______________
correct response after an ____________of ______
has passed
23OPERANT CONDITIONING (CONTD)
24OTHER CONDITIONING CONCEPTS
- Generalization
- Animal or person emits the same response to
similar stimuli - Tendency for a stimulus similar to the original
conditioned stimulus to elicit a response similar
to the conditioned response - Discrimination
- Occurs during classical conditioning when an
organism learns to make a particular response to
some stimuli but not to others - Discrimination stimulus cue that a behavior will
be reinforced
25OTHER CONDITIONING CONCEPTS (CONTD)
- Extinction and spontaneous recovery
- Extinction
- procedure in which a conditioned stimulus is
repeatedly presented without the unconditioned
stimulus - the conditioned stimulus tends to no longer
elicit the conditioned response - Spontaneous recovery
- tendency for the conditioned response to reappear
after being extinguished, even though there have
been no further conditioning trials
26COGNITIVE LEARNING
- Cognitive learning attention and memory
- Says that learning can occur through
_________________________and may not involve
external rewards or require a person to perform
any observable behaviors - Three viewpoints
- Against B. F. Skinner (As far as Im concerned,
cognitive science is the creationism (downfall)
of psychology) - In favor Edward Tolman
- explored hidden mental processes
- cognitive map mental representation in the brain
of the layout of an environment and its features
27COGNITIVE LEARNING (CONTD)
- Three viewpoints
- Also in favor Albert Bandura
- focused on how humans learn through observing
things - Social cognitive learning
- Results from watching and modeling doesnt
require the observer to perform any observable
behavior or receive any observable reward
28COGNITIVE LEARNING (CONTD)
- Learning-performance distinction
- Learning may occur but may not always be measured
by, or immediately evident in, performance - Banduras social cognitive theory
- Emphasizes the importance of ________________,
________________, and ____________________in the
development and learning of social skills,
personal interactions, and many other behaviors
29COGNITIVE LEARNING (CONTD)
- Four processes
- Attention

31BIOLOGICAL FACTORS
- Definition
- Biological factors
- innate tendencies or predispositions that may
either facilitate or inhibit certain kinds of
learning - Imprinting
- inherited tendencies or responses that are
displayed by newborn animals when they encounter
certain stimuli in their environment - Critical or sensitive period
- a relatively brief time during which learning is
most likely to occur
32APPLICATIONS
- Behavior modification
- Treatment or therapy that changes or modifies
undesirable behaviors by using principles of
learning based on operant conditioning, classical
conditioning, and social cognitive learning - Autism
- marked by poor development in social
relationships - great difficulty developing language and
communicating very few activities and interests - long periods of time spent repeating the same
behaviors and following rituals that interfere
with more normal functioning
33APPLICATIONS
- Autism
- symptoms range from mild to severe
- usually appear when a child is 2 to 3 years old
- Biofeedback
- training procedure through which a person is made
aware of his or her physiological responses, such
as muscle activity, heart rate, blood pressure,
or temperature - after awareness of physiological responses, a
person tries to control them to decrease
psychosomatic problems
