Anxiety
The physiological and psychological reaction to an expected danger,
whether real or _______________.
http://allpsych.com/disorders/anxiety/index.html
Anxiety Disorders
_______________Attack
Period of extreme anxiety and physical symptoms such as heart
palpitations, shakiness, dizziness, and racing thoughts. Initial attacks are
often reported to feel like a heart attack due to the heart palpitations. A
medical exam should be conducted to rule out any such condition.
Phobia
An intense fear of a specific object or situation. Most of us consider
ourselves to have phobias, but to be diagnosable, the fear must

_______________
A behavioral technique used to treat phobias in which the client is
presented with the feared stimulus until the associated anxiety
disappears.
Systematic __________________________
A treatment technique where the client is exposed to gradually
increasing anxiety provoking stimuli while relaxing; the goal is for
the client to eventually confront a phobia or fear without the
previously associated anxiety. (Movie Clip: What about Bob?)
(Therapies continued)
________________ Therapy
A type of behavioral treatment where an aversive stimuli is paired
with a negative behavior in hopes that the behavior will change in the
future to avoid the aversive stimuli.
Ex. Chemicals + Alcohol = Sick
Therapy in the 21st Century

& other forms of learning
Operant Conditioning – A simple form of learning in which an
organism learns to engage in behavior because it is reinforced

TYPES OF REINFORCERS
• _____________REINFORCERS
(ex. food, water, & adequate
warmth)
• ______________ or
CONDITIONED
REINFORCERS (ex. money)
• _____________REINFORCERS
(ex. Stephan and Cody were two
mentally disabled boys who
seldom smiled at other people.
Dr. Hopkins used a procedure in
which he would take them for
walks, and if they smiled at
passers by, he would give them
some pieces of M & M's candy.
This procedure caused Stephan
and Cody to smile much more
often than they had before.
• _____________REINFORCERS
(ex. Insect bite itches, Scratch it.)
How do our M & M friends demonstrate the idea of Operant
Conditioning? What kinds of behavior are elicited first? What about
____________ (138) & ______________(138-139)? What about
_____________ (142) & __________________________________?
LET’S LOOK AT…
Positive Reinforcement vs. Negative Reinforcement vs.
Punishment

Child‘s Behavior

(time 4:28)
REWARDS
vs.
• Reward and Reinforcer can
be used interchangeably
• What is rewarding to you
may not be rewarding to
another.
PUNISHMENTS
• Punishment doesn’t
suggest what to do.
• Works only if guaranteed
& consistent
• Severely punished may
withdraw (Seligman)
• Can create hostility
• May be imitated (Monkey
see…)
• Draws attention to it

SCHEDULES OF
REINFORCEMENT
• CONTINUOUS vs. _________________
• INTERVAL (____________) SCHEDULES
– Fixed
– Variable
• RATIO (_______________) SCHEDULES
– Fixed
– Variable
1. ___________________________-- the first correct response after a
set amount of time has passed is reinforced (i.e., a consequence is
delivered). The time period required is always the same.
2. _________________________-- the first correct response after a set
amount of time has passed is reinforced. After the reinforcement, a new
time period (shorter or longer) is set with the average equaling a
specific number over a sum total of trials.
3. _______________________-- a reinforcer is given after a specified
number of correct responses. This schedule is best for learning a new
behavior.
Notice that behavior is relatively stable between reinforcements, with
a slight delay after a reinforcement is given. Also notice the number
of behaviors observed during the 30 minute time period is larger than
that seen under either of the interval schedules.
4. ______________________-- a reinforcer is given after a set number
of correct responses. After reinforcement the number of correct
responses necessary for reinforcement changes. This schedule is best for
maintaining behavior.
