Historical Conceptions of Abnormal Behavior

illness
Consequences of the Biological Tradition

The Psychological Tradition: Ancient Contributions
 Plato
 more humane treatment

were insane, then they shouldn’t be
punished like a normal person.

Psychology

and Development
 Work with patients suffering
from hysteria
 Jean Charcot and hypnosis
 Free association
 Resistance
 Repression
 Psychodynamic Theory
Psychodynamic Theory

Behavioral Theories of Abnormality
 Classical Conditioning
 Operant Conditioning
(Also two more theories, but we’re not talking about
them today)
 Modeling and Observational Learning
 Observational Learning
The Behavioral Model and the Psychological
Tradition
 Classical Conditioning (Pavlov; Watson)
 Ubiquitous form of learning
 Pairing neutral stimuli and unconditioned stimuli
 Conditioning was extended to explain fear
acquisition
Classical Conditioning
 Before Conditioning:
CS (bell)
US (meat powder)
No CR (no salivation)
 During Conditioning:
CS
signals

UR (salivation)
US
UR
produces
After Conditioning:
CS (bell)
CR (salivation)
produces
Behavioral Model
 Operant Conditioning (Thorndike; Skinner)
 Another ubiquitous form of learning
 Voluntary behavior is controlled by consequences
 Operant Conditioning: R  S
 Classical Conditioning: S  R
Operant Conditioning
 Positive Reinforcement
 Negative Reinforcement
 Punishment
Cognitive Theories of Abnormality
 Types of cognition
 Causal attributions
 Control beliefs
 Learned helplessness
 Dysfunctional assumptions
Some Common Global Dysfunctional
Assumptions
I should be
loved by
everyone for
everything I
do.
I must have
perfect self
control.
Once
something
affects my life,
it will affect it
forever.
It is better to
avoid problems
than to face
them.
I should be
terribly upset
by certain
situations.
The Behavioral Model

Ivan Pavlov (1849-1936)

 Unconditioned response (UCR)
 Conditioned stimulus (CS)
 Conditioned response (CR)
The Behavioral Model
 Classical Conditioning – Concepts

 Extinction
 Introspection
The Behavioral Model
 Behaviorism

The Behavioral Model and Behavior Therapy
 Mary Cover Jones

exposure and modeling

behavior

 Reinforcements
 Punishments
 Behavior “shaping”
The Scientific Method and an Integrative Approach
 Defining and studying psychopathology
 Requires a broad approach
 Multiple, interactive influences
