Stimulus Class
A
A group of stimuli that share some common property.
3
Q
3 Types of Stimulus Classes
A
Formal: They look the same in some way.
Temporal: They precede or follow a response.
Functional: They produce the same response.
4
Q
Two kinds of stimulus changes:

Stimulus changes produced direcetly by the behavior.
A
automatic
7
Q
What is the environment?
A
- The circumstances in which the organism exists
- Includes all of the stimuli capable of affecting the organism
- Includes stimuli occurring within the skin
8
Q
The environment is never…
A
unchanging
9
Q
All behavior occurs in a…
A
context
10
Q
Behavior
A
- Iteraction between the organism and environment
- Anything an organism does.
- Behavior never stops – ever – it is a constant flow or stream
11
Q
Response
A
An individual instance of behavior
12
Q
Stumulus Response Learning (3 qualities)
A
Respondent behavior (reflex)
- Specific responses to specific stimuli
- Selected through evolution – hardwired into our system
- Seemingly linked to species survival
13
Q
A reflex is a…
A
Stimulus response relation (A stimulus elicits a reflexive response)
14
Q
Respondent extinction
A
The CS is repeatedly presented without the US, the CR will decrease. This decrease in the CR due to repeated CS presentation is called respondent conditioning.
15
Q
Reinforcement can come in two ways…
A
- Socially Mediated
- Automatic
16
Q
In order for a stimulus change to function as a negative reinforcer
A
some aversive condition must exist prior to the behavior.
17
Q
Negative reinforcement comes in two ways…
A
Escape
Avoidance
18
Q
What is extinction?
A
The withholding of a reinforcer for a previously reinforced behavior
19
Q
What is an extinction burst?
A
An increase in the behavior or other behaviors
that previously produced the specific reinforcer
20
Q
What are two qualities of an extinction burst?
A
- An increase in members of a response class
- You may also see other emotional responses
21
Q
What is spontaneous recovery?
A
A small resurgence in the behavior after fully
extinguished
22
Q
What is resurgance?
A
When you place a behavior on extinction, and it becomes extinguished,it is possible for other behaviors that were previously extinguished to re-emerge.
23
Q
Once the behavior has reached 0, we say the behavior has been..
The process is…
A
extinguished
extinction
24
Q
Punishment is not…
A
extinction

Reinforcement
38
We need to focus on shifting:

- Intermittent programmed reinforcement to naturally occurring reinforcement.
39
What is ratio scheadule?
Reinforcement is delivered based on the number of responses emitted.
40
What is interval scheadule?
Some amount of time must pass before a response produces reinforcement.
41
What is fixed ratio?
REINFORCEMENT IS DELIVERED AFTER A
| FIXED NUMBER OF RESPONSES.
42

develop clear guidelines and monitoring procedures
60
What are the myths of punishment? (5)
- Aversive procedures are non-normalized and unnatural
- Reinforcement works better than punishment
- Punishment should be a procedure of last resort
- Treatment hierarchies protect people
- Nonaversives can treat all problem behavior
61
What is a punisher?
A STIMULUS CHANGE that decreases the p
62
What is positive punishment?
A stimulus is presented following some behavior and this produces a decrease in the future occurrences of the behavior
63
What is negative punishment?
A stimulus is removed following some behavior and this produces a decrease in futures occurrences of the behavior.
64
Types of punishers...
- Unconditioned punisher
| - Conditioned punisher
65
How to make a punisher effective? (5)
- Introduce a punisher at high intensity
- Make it immediete
- Select a dence schedule
- Decrease motivation to respond
- Punish eary on in the chain
66
What are possible punishment side effects? (3)
- Countercontrol (efforts made by the organism to escape the punishing event)
- Conditioned emotional or aggressive reactions
- Generalized suppression (a suppression of all responding)
67
What is behavioral contrast?
If a behavior is punished in one environment, it may increase in another environment.
68
What is the dead man's rule?
If a dead man can do it, it aint before.
69
Punishers are defined functionally. What does that mean?
-They are defined by what they do (decrease the behaviors they
follow)
70
What are the realities of using punishment? (3)
- Most people are uncomfortable with it
- Many people rely on punishment because delivering punishment can negatively reinforce the punisher’s behavior
- It should always be considered a treatment component
71
What are positive punishment procedures? (4)
- Reprimand
- Response blocking
- Contingent work/effort
- Overcorrection
72
What are the characteristics of a reprimand?
-Also a commonly ineffective punisher
-May be effective for minor behaviors or
when heavy alternative reinforcement is
available
-Best used sparingly, or combined with
other interventions
73
What is response blocking?
| What is it useful for?
- Physically intervening to block response completion
- Often a treatment component
- Useful for chronic behaviors such as stereotypy
74
What is RIRD
-Response interruption and redirection (RIRD)
-Response blocking plus redirection to a high
probability behavior
75
What is contingent work/effort?
- Required effort expenditure following behavior
| - There is no topographical relation between effort and problem behavior
76
What is overcorrection and the two types? What are they good for?
Restitutional: Improve environment to state better than prior to behavior. Very effective with destructive behavior.
Positive practice: Repeatedly practice engaging in appropriate behavior. Very good for behaviors that require physical exertion
77
Notes on overcorrection (4)
- Problem behavior will typically occur when first implementing the procedure
- Always do one more repetition than you think necessary
- Provide repeated verbal instructions during procedure
- Have extremely high standards
78
Types of negative punishment
- Response cost
| - Time out
79
Notes on response cost:
- Most effective when combined with a token economy
- Don’t let the individual dig themselves into a deep hole
- Develop a rule regarding loss per unit of time
- Loss of reinforcement should be obvious
- Develop multiple levels of loss
80
What is time out?
| How do we make time out effective?
```
-Removal of all reinforcement for period of
time
-A very common punishment intervention
-Also overused and sometimes ineffective
-In order for time out to be effective, the time-in
environment must be reinforcer dense
-Not a good option for escape-maintained
behaviors
```
81
What are the two types of time outs?
Nonexclusionary: Not removed from location, but no reinf available
Exclusionary: Removed from location and directed to a safe confined space
82
What can we also do to make time out effective? (4)
- Clearly define behaviors that will result in TO
- Make it pretty short
- Develop TO exit criteria
- Begin reinforcement when they get back
83
How are new behaviors formed?
-Through this process of reproduction, variation, and selection, new behaviors are born
84
What is differential reinforcement?
-It is the reinforcement of certain behaviors while placing others on extinction
85
How also is a new behavior formed?
Reinforcing some behaviors and placing others on extinction.
86
What are the types of differential reinforcement?
- Incompatiable behavior
- Other behavior
- Alternative behavior
- High rates of behavior
- Low rates of behavior
87
What is differential reinforcement of incompatible behavior?
Reinforce a behavior than cannot be performed at the same time as the problem behavior
88
What is differential reinforcement of other behavior?
-Reinforce any behavior that occurs after the problem behavior has not occurred for some time.
89
What are variations in the reinforcement of other behavior? (5)
Resetting Interval: Any occurrence of the behavior results in a reset of the amount of time
necessary to earn reinforcement
Continued Timing: Interval does not reset. The individual must go the remainder of the interval plus another interval
Momentary DRO: You reinforce if behavior is absent at the end of some interval of time.
90
What is differential behavior of alternative behavior?
Reinforce an appropriate form of the behavior that gets the same consequence.
91
What is differential reinforcement of high rates of behavior?
You reinforce only when behavior occurs faster than a certain level.
92
What is differental reinforcement of low rates of behavior?
You reinforce only when behavior occurs slower or less than a certain level.
93
What is positive reinforcement?
A stimulus is added to the environment following a response and the result is an increase in future behavior
94
What is negative reinforcement?
A stimulus is removed from the environment following a response and the result is an increase in future behavior.
95
Who was the founder of behaviorism?
Watson
96
What was Skinner's contribution?
- Skinner expanded the theory and study of behaviorism
- Sought to include all human behavior into the field of study
- Came up with ABC
- Thoughts and feelings should be counted as behavior (the radical part)
97
What are the two minds of behavior?
Operant: Behavior learned through consequences
Respondent: Reflexes
98
What is the purpose of science?
Better understand the phenomena of interest.
99
What are the three levels of understanding?
- Description
- Prediction
- Influence/control
100
Attitudes of a good scientist:
Determinism: universe follows laws
Empiricism: knowlege is achieved through sensing
Experiment
Replication
Parsimony
Philosophic doubt
101
We never explain behavior by...
other behavior
102
Labeling behavior doesn't...
explain behavior
103
What is mentalism?
Generally refers to explanations of behavior that infer non-physical “mental” processes as causes.
104
What are explanatory fictions?
Explanations that don’t actually explain or contribute to understanding; typically circular.
105
In behaviorism, what controls behavior?
The environment.
106
What are the dimensions of ABA?
Applied: Socially significant behaviors targeted.
Behavioral: Target the specific behavior in need of improvement; behaviors are observable and measureable.
Analytic: fundamental relations are discovered through manipulation of the independent variable while observing effects on the dependent variables
Technological: All procedures are described adequately to be replicable.
Conceptually Systematic: Procedures are derived from, and described in relation to, basic principles.
Generality: Behavior change lasts over time, is seen in other environements, and spreads to other behaviors.
Effective: Behavior changes to a socially significant degree.
107
What is a reinforcer?
| Name the three parts!
A STIMULUS CHANGE THAT INCREASES THE
FUTURE FREQUENCY OF THE BEHAVIOR IT
IMMEDIATELY FOLLOWS.
108
Reinforcement changes the future responses in...
the same response class
109
What is automaticity?
A STIMULUS CHANGE THAT INCREASES THE
FUTURE FREQUENCY OF THE BEHAVIOR IT
IMMEDIATELY FOLLOWS.
110
What is rule governed behavior?
Behavior controlled by statements about contingencies
111
What is contingency shaped behavior?
Controlled directly by the immediate consequences
112
What are uncondionted reinforcers?
Require no learning to function as reinforces.
113
What is stimuls control?
- A response occurs in the presence of a stimulus, but not in it’s absence
- A response occurs in the absence of a stimulus, but not in it’s presence
114
What is a discriminative stimulus? (SD)
A stimulus that “signals” reinforcement is available for a certain response.
115
What is a delta stimulus?
A stimulus that signals no reinforcement is available for a certain response.
116
What's as SDP?
Some stimuli are associated with punishment for certain behaviors.
117
What is a prompt?
Supplemental stimuli that increase the
| likelihood that a response will occur
118
What are common response prompts?
Gestural
Modeling
Physical
Verbal
119
How do you prompt fade?
Remove the prompt while the SD remains ◦ The SD comes to control the response
120
What are the methods of prompt fading?
Most-to-least fading
Least-to-most fading
Time delay fading
Graduated guidance
121
How do you do most to least prompt fading?
- Start with most efficient prompt
- Systematically decrease prompts with each successful response
- If an error is made, you return to the last successful prompt
122
How do you do least to most prompt fading?
- Start with the least intrusive prompt
- If no response or an incorrect response move to the next least intrusive prompt
- Continue until you reach a prompt that results in the correct response
123
How does time delay prompting work?
- The form of the prompt does not change, only the delay to the prompt
- Upon the first presentation of an SD, the prompt is immediately delivered
- Upon the second presentation of the SD, the prompt is delivered after a few seconds
- This continues until no prompt is necessary
124
What is graduated guidance?
- In close physical proximity to learner, provide assistance as needed
- Immediately begin decreasing physical proximity
- Increase physical proximity as errors occur or are predicted to occur
125
Tips on prompts and prompt fading
- A difficulty in transferring control of the response from the prompt to the SD
- You should try to fade prompts as quickly as possible
- Lingering on one prompt level too long can result in prompt dependency
- If you find prompt dependency has developed and you cannot remove the prompt, consider switching to a different prompting hierarch.
126
What are motivating operations?
Stimulus changes in your environment (things that happen to you) that
(1) influence the value of other stimuli as reinforcers (value-altering effect) and
(2) influence the probability of specific behaviors (behavior-altering effect).
127
What are the two kinds of motivating operations?
```
Establishing operation (deprivation)
Abolishing operation (satiation)
```
128
What are the two effects of an establishing operation?
```
Establishing effect (value-altering)
Evocative effect (behavior-altering)
```
129

```
Abolishing effect (value altering)
Abative effect (behavior altering)
```
