Characteristics of behavior
What people say and do
Involves actions, not labels
Involves physical dimensions that can be measured
Can be observed, described, and recorded
Has an impact on the environment (physical or social) in which it occurs
Is lawful (systematically influenced by environmental events)
May be overt or covert
Example of behavior as involving actions not labels
Joe was angry (label) and slammed the door (action)
Label could be an emotion (not the focus)
Describing behaviors helps paint a picture
When a parent says a child has meltdowns
Important to ask what that looks like
Want to define behavior through quantitative measurements
- Frequency (how often it occurs)
- Duration (for how long)
- Intensity (magnitude of the behavior)
- Latency (how long it takes for the behavior to occur after a stimulus)
Given a specific goal, it makes sense to focus on a single dimension
Overt behavior
Other people can see it
Covert behavior
Behavior happening internally
Example: obsessions
Still must make the definition of the behavior very clear
Characteristics of behavior modification
- Focus on behavior (excesses vs deficits)
- Based on basic behavioral principles (Skinner and Pavlov). Originally derived from experimental research with lab animals by Skinner
- Emphasis on current environmental events (antecedents and consequences)
- Procedures are clearly described
- Measurement of behavior change (immediate and long-term)
- De-emphasis on the past
- Rejection of underlying causes (motivations, drives). Focus only on what can be observed and recorded
- Implemented by people in everyday life
Developed as a rebellion to psychoanalysis and psychodynamics. Follows the scientific method.
Behavioral excesses
Behavior is happening too much. Goal is to reduce or eliminate it
Behavioral deficits
Behavior is not happening enough
Antecedents
Happen before the behavior
Consequences
Happen after behavior
Importance of measuring behavior change
We want to see if treatment leads to improvement and lasting impact
Common misconceptions about behavior modification
- Relies on punishment
- Uses bribes
- Simplistic
- Ignores the real causes of behavior, just treats the symptoms
- Leads to people controlling each other
Ruins intrinsic motivation
- Makes people dependent on external incentives
- Dehumanizes people
- It only works with kids and individuals with disabilities
Punishment
Last-case scenario. Doesn't work as well. Potential for abuse.
Response to the critique that behavior modification ignores the real causes of behavior
Symptoms are the problem. Causes are insignificant when they don't produce the symptoms. Symptoms are what the patient cares about
Behavior modification areas of application
- Developmental disabilities
- Mental illness
- Education and special education
- Rehabilitation
- Community psych (using garbage cans for example)
- Clinical/counseling psych
- Business and industry (modifying consumer behavior)
- Self-management
- Child management/parenting
- Prevention
- Sports
- Health psych and behavioral medicine
- Gerontology (working with older individuals)
Behavior is not
A static characteristic of a person
Physical dimensions of behavior
frequency, duration, intensity, latency
Behavior as lawful
Its occurence is systematically influenced by environmental events
Another name for covert behavior
Private events
Type of behaviors that the field of behavior modification primarily focuses on
Overt or observable behaviors
Analyzing behavior
identifying the functional relationship between environmental events and a particular behavior to understand the reasons for behavior or determine why a person behaved as they did
Modifying behavior
developing and implementing procedures to help people change their behavior
Behavior modification and labeling
Behavior modification de-emphasizes labeling
For example, behavior modification is not used to change the autism label. It is used to change problems behaviors exhibited by children with autism
Target behavior
Behavior to be modified
Scientific study of behavior is called the
Experimental analysis of behavior or behavior analysis
The scientific study of human behavior is called the
Experimental analysis of human behavior or applied behavior analysis
Controlling variables
The goal of behavior modification is to identify events in the immediate environment that control behavior and alter them to modify the behavior
Rejection of hypothetical underlying causes of behavior
Skinner has called such explanations "explanatory fictions" because they can never be proved or disproved and are thus unscientific
Pavlov
Demonstrated that a reflex (salivation in response to food) could be conditioned to a neutral stimulus
A dog salivated in response to the sound of a metronome alone. Pavlov called this a conditioned reflex
Thorndike law of effect
A behavior that produces a favorable effect on the environment is more likely to be repeated in the future
Skinner
Explained the distinction between respondent conditioning (conditioned reflexes described by Pavlov and Watson) and operant conditioning, in which the consequence of behavior controls the future occurrence of the behavior (as in Thorndike's law of effect)
Token economy
Motivational procedure for institutional patients
Rehabilitation
Process of helping people regain normal function after an injury or trauma
Behavioral interventions within community psychology
Are designed to influence the behavior of large numbers of people in ways that benefit everybody
Behavior modification in clinical psychology
Often called behavior therapy
Behavior modification in sports psychology
Shown to result in better athletic performance than traditional coaching procedures
Behavioral assessment
Measurement of a target behavior or behaviors
Purposes of behavioral assessment
- Decide if the problem exists and treatment is necessary (initial data collection phase)
- Decide on the best treatment (primary reason for initial behavioral assessment)
- Measure treatment effects: Was the treatment helpful?
- As a treatment component (reactivity): Measuring a behavior can have a treatment effect. Changing behaviors as a product of being observed
Indirect assessments
Type of behavioral assessment
Interviews, questionnaires, rating scales
Direct assessments
Type of behavioral assessment
Critical component to behavior modification
Direct observation and recording of the target behavior as it occurs
Recording behavior components
Defining target behavior
Defining the target behavior
Describe what the person does and says (avoid labels)
Use active verbs (objective and unambiguous)
No inference about internal states or motivation
Defined so that two people could agree (interrater or interobserver reliability)
Who should observe and record the target behavior?
An independent observer
Self-monitoring as an alternative or in addition to the independent observer (if behavior is too infrequent or happens when no one is there to observe)
When and where to record a target behavior
Define observation periods
Record in natural settings (where behavior usually occurs) or contrived settings (analogue, where variables could be manipulated)
Structured vs unstructured settings
Structured settings
The observer sets up a behavior to occur
Continuous recording
Recording method
Recording a dimension of behavior throughout an entire time period
Real-time recording
recording method
Both frequency and duration information
Product recording
Recording method
Doesn't require direct observation. Observer doesn't have to be present when the behavior occurs
How many cigarettes in a pack at the beginning of the day vs how many at the end
Indirect assessment method that can be used when a behavior results in a certain tangible outcome that you are interested in
Interval recording
Recording method
Take snippets of time to observe the behavior.
The observation period is divided into intervals. Did the behavior occur during an interval?
Choose a recording instrument
Recording must be immediate and practical
Reducing reactivity
Waiting until person being observed becomes accustomed to the observer or to self-monitoring
Record surreptitiously through observation windows or with participant observers
Interobserver reliability
For frequency or duration recording: smaller number dividied by the larger number
For interval or time sample recording:
For frequency within interval recording:
Direct assessment vs indirect assessment
Direct assessment usually is more accurate than indirect assessment
In direct assessment, observer is trained specifically to observe target behavior
In indirect assessment, information on the target behavior depends on people's memories
Self-monitoring
Client observes and records his or her own target behavior
Natural setting
Consists of the places where behavior typically occurs
Observation in a natural setting is likely to provide a more representative sample of the target behavior than a contrived setting
Contrived setting
More controlled than a natural setting. Variables that influence the behavior are easier to manipulate
In behavior modification, the people observing and recording the target behaviors
Are usually trained assistants
Frequency reported as rate
Frequency divided by the time of the observation period
Real-time recording
method in which the exact time of each onset and offset of the target behavior is recorded
Difference between duration and latency
Latency is the time from some stimulus to the onset of the behavior
Duration is the time from the onset of the behavior to its offset
Percentage of opportunities
Reporting results as the number of times behavior occurred divided by the number of opportunities for the behavior to have occurred
Benefit of product recording
Observer does not have to be present when the behavior occurs
Drawback of product recording
Cannot always determine who engaged in the behavior that led to the product recorded
To use interval recording
The observer divides the observation period into a number of smaller time periods, observes the client throughout each consecutive interval and records whether the behavior occurred in that interval
Partial interval recording vs whole interval recording
Partial: once interval is marked, observer does not have to observe until the next interval begins
Whole: Occurrence of the behavior is marked only when the behavior occurrs throughout the entire interval
Frequency-within-interval recording
the observer records the frequency of the target behavior but does so within consecutive intervals of time in the observation period
Time sample recording
divide the observation period into intervals of time, but you observe and record the behavior during only part of each interval
Observation periods are separated by periods without observation
In interval recording or time sample recording
The level of the behavior is reported as the percentage of intervals in which the behavior occurred
Reactivity may be undesirable
Because the behavior recorded during the observation period is not representative of the level of behavior occurring when observer isn't present or there is no self-monitoring
Ways to reduce reactivity
Wait until the people who are being observed become accustomed to the observer
Have observer record behavior without people knowing they are being observed
Use a participant observer: person who is normally in the setting when the target behavior occurrs
Minimally acceptable interobserver reliability
80% but 90% or better is preferred
Graph
Shows level of behavior over time
Makes it easier to compare the level of behavior before and after treatment
Used in research to evaluate behavior change
Purpose of research in behavior modification
Evaluate the effectiveness of treatment
Demonstrate a functional relationship between environmental events and behavior
Research method in behavior modification
Measure dependent variable (target behavior)
Manipulate independent variable and demonstrate a change in the target behavior
replicate
A-B design
One baseline and one treatment phase
Baseline: no treatment is being implemented. Initial data assessment
Not a true research design because there is no replication
Does not demonstrate a functional relationship
Used in clinical practice, self-management projects
Phase line
Separates baseline phase from intervention phase
A-B-A-B Reversal design
Baseline and treatment phases implemented twice
Demonstrates a functional relationship because of replication
Potentially not ethical/feasible to remove treatment
Multiple baselines across subjects design
Two or more subjects with the same target behavior in the same setting.
Treatment is staggered over time across subjects (different baseline lengths)
Multiple baselines across behaviors design
Two or more behaviors of the same subject
Treatment is staggered across behaviors
Multiple baseline across settings design
Two or more settings with the same target behavior of the same subject
Treatment is staggered across settings
Alternating treatments design
Compare baseline and treatment or two treatments
Conditions are alternated rapidly (every other day or every other session)
A functional relationship is demonstrated when the data are separated between the two conditions
Also called multi-element design
Changing the criterion design
Baseline and treatment phase
Multiple performance criteria (goals) in the treatment phase
A functional relationship is demonstrated when the behavior matches the performance criteria
Because the subject's behavior changes each time the performance criterion changed, it is unlikely that a confounding variable was responsible
Competing response
a behavior that is incompatible with the target behavior
Follow-up period
Long period after treatment has been implemented
Typical behavior modification graph
Time indicated on the x-axis (abscissa)
Level of behavior indicated on the y-axis (ordinate)
Purpose of a research design
to determine whether the treatment (independent variable) was responsible for the observed change in the target behavior (dependent variable) and to rule out the possibility that extraneous variables caused the behavior to change.
Extraneous variable
Synonym for confounding variable
Any event that the researcher did not plan which may have affected the behavior
Demonstrating a functional relationship
When a researcher shows that the behavior modification procedure causes a target behavior to change
A functional relationship is established if
A target behavior changes when an independent variable is manipulated, while all other variables are held constant.
The process is replicated or repeated one or more times and the behavior changes each time.
A-B-A-B design also called the reversal design because
after the first treatment phase, the researcher removes the treatment and reverses back to baseline
Considerations for A-B-A-B design
May not be ethical to remove treatment if behavior is dangerous
Must be certain that level of behavior will reverse when treatment is withdrawn to demonstrate functional relationship
Can you actually remove treatment after implemented
