Exam 1 Flashcards
Indirect Assessment
involves using interviews, questionnaires, and rating scales to obtain information on the target behavior from the person exhibiting the behavior or from others
- does not occur when the target behavior occurs but relies on an individual’s recall of the target behavior
Direct Assessment
a person observes and records the target behavior as it occurs
Defining Target Behavior
describe(avoid labels)
use active verbs
no inference
defined for agreement
Continous recording
the observer observes the client continuously throughout the observation period and records each occurrence of the behavior. To do
so, the observer must be able to identify the onset and the offset (or beginning
and end) of each instance of the behavior
latency
the time from some stimulus or event to the
onset of the behavior. You measure latency by recording how long it takes the person to initiate the behavior after a particular event occurs.
Percentage of opportunities
the observer records the occurrence of a behavior in relation to some
other event (e.g., learning trial, response opportunity).
* “I put the toilet seat down five times today!!”
Product Recording
the outcome or permanent product
of the behavior is recorded as an indication of the occurrence of the behavior
Partial interval recording
observer scores the interval if the behavior occurred during any part of the interval
takes less time and effort; The observer records the behavior only once during the interval,
regardless of how many times the behavior occurs or how long it lasts
whole interval recording
the occurrence of the behavior is marked in
an interval only when the behavior occurs throughout the entire interval
If the behavior occurs in only part of the interval, the behavior is not scored as occurring
in that interval
Time sampling recording
you divide the observation period into intervals of time, but you observe and record the behavior during only part of each interval. The observation periods are separated by periods without observation
A-B Design
simplest type of design used in behavior modification has just two phases: baseline and treatment.
- does not demonstrate a functional relationship because treatment is not replicated
most often used in applied, nonresearch situations, in which people are more interested in demonstrating that behavior change has occurred than in proving that the behavior modification procedure caused the behavior change
example of A-B Design
a self-management project to show whether your behavior changed after you implemented a behavior modification procedure
A-B-A-B (reversal design)
baseline and treatment phases are implemented twice. It is called a reversal design because after the first treatment phase, the researcher removes the treatment and reverses back to baseline. This second baseline is followed by replication of the treatment
Demonstrates a functional relationship
Variations
Considerations
Multiple Baseline Design Across Subjects
a baseline and a treatment phase for the same target behavior of two or more subjects
Multiple Baseline Design Across Behaviors
a baseline and treatment phase for two or more behaviors of the same subject
Multiple Baseline Design Across Settings
is a baseline and treatment phase for two or more settings in which the same behavior of the same subject is measured
ABAB vs Multiple Baseline
A-B-A-B design can also have two baseline phases and two treatment phases, but both baseline and treatment phases occur for the same behavior of the same subject in the same setting. With the multiple-baseline design, the different baseline and treatment phases occur for different subjects, or for different behaviors, or in different settings.
Why do we like multiple baseline design?
functional relationship
treatment is replicated
behavior change as result
Alternating Treatments Design
e conducted in rapid succession and
compared with each other. For example, treatment is implemented on one day,
baseline the next day, treatment the next day, baseline the next day
Functional relationship can be demonstrated
a baseline or treatment phase is conducted until a number of data points are collected (usually at least three) and there is no trend in the data. A trend means the data are increasing or decreasing across a phase.
Compare baseline and treatment (two or
more)
Conditions are rapidly alte
Example of Alternating Treatment Design
A teacher wants to determine whether violent cartoons lead to aggressive behavior in preschool children. On one day, the preschoolers do not watch any cartoons (baseline) and the teacher records the students’ aggressive behavior. The next day, the students watch a violent cartoon and the teacher again records their aggressive behavior. The teacher continues to alternate a day with no cartoons and a day with cartoons. After a few weeks, the teacher can determine whether a functional
relationship exists. If there is consistently more aggressive behavior on cartoon days and less aggressive behavior on no-cartoon days, the teacher has demonstrated a functional relationship between violent cartoons and aggressive behavior in the preschoolers.
Changing criteria design
baseline and treatment phase but with goals
is, successive goal levels for the target behavior specify how much the target behavior should change during treatment. The effectiveness of treatment is determined by whether the subject’s
behavior changes to meet the changing performance criteria. That is, does the subject’s
behavior change each time the goal level changes
Reinforcement
The occurrence of a particular behavior is followed by an immediate consequence that results in the strengthening of the behavior. (The person is more likely to engage in the behavior again in the future.)
Examples of reinforcement
Guy taunts girl and gets slapped, guy continues to taunt girl in future
Mom asks kid nicely to make bed, kid makes bed, mom continues to ask kid nicely to make bed
Operant Behavior
A behavior that is strengthened through the process of reinforcement
acts on the environment to produce a consequence and, in turn, is controlled by, or occurs again in the future as a result of, its immediate consequence.
Reinforcer
The consequence (stimulus or event) that
follows operant behavior and strengthens
operant behavior
Positive Reinforcement
The occurrence of a behavior is followed by the addition of a stimulus (a reinforcer) or an increase in the intensity of a stimulus,
which results in the strengthening of the behavior.
Negative Reinforcement
The occurrence of a behavior is followed by the removal of a stimulus (an aversive stimulus) or a decrease in the intensity of a stimulus, which results in the strengthening of the behavior
Stimulus
an object or event that can be detected by one of the senses, and thus has the potential to influence the person
Negative reinforcement vs punishment
Negative reinforcement (like positive reinforcement) increases or strengthens a behavior. Punishment, in contrast, decreases or weakens a behavior.
Unconditioned Reinforcer
Biologically determined
they function as reinforcers the first time they are presented to most human beings; no prior
experience with these stimuli is needed for them to function as reinforcers
Ex: Food, water, human contact (warmth),
oxygen, sexual contact, escape from cold,
heat, pain, extreme levels of stimulation
