What is the function of ABA?
ABA uses the functions of behavior to understand behavior and why it occurs. When you accurately identify the function of a behavior, you answer the question: What does this person “get” out of engaging in this behavior. This answer allows you to select function-based interventions to address the behavior.
What is applied behavior analysis (ABA)?
In applied behavior analysis, these areas would be more clearly defined and treatment planning would be designed with detailed and comprehensive methods but overall, ABA services are designed to improve the quality of life of the people receiving the intervention.
How important are percentages in ABA research?
That is not to say the percentages are unimportant but simply that graphing data can increase the speed at which analyses and interpretations can be made. This is especially true when taking into account that a child might have a number of different interventions in place within an ABA programme and each one needs to be continuously analysed.
What is the importance of data analysis in ABA?
In ABA, data is used as the foundation for making decisions regarding the client or students treatment. Data is analyzed to inform the clinician whether progress is being made or not. Based on the data, the clinician will decide whether treatment should be modified in any way or continued in the same manner.
Why is fixed-ratio important?
Essentially, the subject provides a set number of responses, then the trainer offers a reward. One advantage of a fixed-ratio schedule is that it produces a high, steady rate of responding with only a brief pause after the delivery of the reinforcer.
Why is scheduling reinforcement important?
The schedules of reinforcement used during the training and maintenance process can have a major influence on how quickly a behavior is acquired, the strength of the response, and how frequently the behavior is displayed.
Why is schedule thinning necessary?
As noted by Tiger et al. and others, schedule thinning may be necessary when the newly acquired communication response occurs excessively, to the extent that reinforcing it consistently is not practical in the natural environment.
How do you implement a DRL?
To implement DRL, a teacher delivers reinforcement when the frequency of an unwanted behavior is reduced during a given period of time. Because the behavior is appropriate for the classroom, the goal is not to eliminate it entirely but rather to increase the intervals between instances of the behavior.
How are reinforcement schedules used to strengthen specific behavior?
In operant conditioning, a fixed-ratio schedule reinforces behavior after a specified number of correct responses. This kind of schedule results in high, steady rates of responding. Organisms are persistent in responding because of the hope that the next response might be one needed to receive reinforcement.
Why do variable ratio schedules produce steady rates of responding?
Variable ratio schedules produce steady rates of responding because it's impossible to determine which response will result in a reinforcer.

What is demand fading ABA?
demand fading. To decrease an individual's challenging behavior maintained by escape from demands, demands are initially removed, then, as the challenging behavior remains low, demands are gradually reintroduced. deprivation.
What is the best way to prevent ratio strain?
To avoid ratio strain, it is important to plan for gradual changes in behavior. If you note a decrease in the effectiveness of a reward, it may be time to adjust behavioral expectations or increase positive reinforcements to keep your child motivated.
When implementing DRO What do you do when the problem behavior occurs?
Implementing DRO: Start a stop watch with the designated interval. At the end of each interval, deliver the reinforcer ONLY IF the problem behavior hasn't occurred. For instance, if the DRO interval is 10 minutes, any time the problem behavior occurs, 10 minutes is reset on the stopwatch again.
In which situations are DRL used?
Abstract. Differential reinforcement of low rates of responding (DRL) is a technique in which a positive reinforcer is delivered at the end of a specific interval if a target behavior has occurred at a criterion rate. Traditionally, it has been used in educational settings to manage classroom behaviors.
How can consistency and routine help to increase the display of a desired behavior?
How can consistency & routine help to increase the display of a desired behavior? Predictability that goes along with consistency & routine helps learners focus on what is important. A pivotal skill that helps individuals "learn to learn"? Responding to multiple cues in the environment.
Why Conduct Baseline Probes
The purpose for conducting baseline probes is to establish a control in an experiment. In order to know whether or not an intervention (independent variable) changed a behavior (dependent variable) you would need a reference as to how often the behavior occurs prior to starting an intervention.
Ascending
Sometimes during baseline a behavior path is ascending which means the behavior is increasing. If the behavior is a desirable behavior, this may mean that no intervention is necessary since the learner is acquiring the skill naturally.
Descending
Sometimes during baseline a behavior path is descending which means the behavior is decreasing. If the behavior is an undesirable behavior, this may mean that no intervention is necessary since the learner is acquiring the skill naturally.
Variable
Sometimes a baseline data path looks variable or is up and down. This is typically caused by extraneous factors in the environment. Sometimes, you can pinpoint what is causing this variability and an intervention may not be necessary. Otherwise, you should wait for the behavior to be emitted at a stable rate before implementing an intervention.
Stable
A stable baseline means that the respondent is emitting a behavior at the same rate and it is time to implement an intervention.
How to Use a Baseline to Develop Experimental Control
In order for a baseline to be used to establish a functional relationship between the independent and dependent variables also known as experimental control, the follow things must occur: Prediction, Affirmation of Consequent, Verification and Replication
Prediction
Prediction is when a behavior analyst predicts that once a stable baseline is established, without any intervention, the behavior will occur at the same rate in the future.
What is data in ABA?
Data is defined as factual information (such as measurements or statistics) used as a basis for reasoning, discussion, or calculation (Merriam-Webster Dictionary) In ABA, data is used as the foundation for making decisions regarding the client or students treatment. Data is analyzed to inform the clinician whether progress is being made or not.
What is data collection in ABA?
A clinician decides which type of data should be collected based upon the type of information they are seeking, what behavior or response they are assessing, and other factors such as ease of data collecting.
What does ABA do?
By Amelia Dalphonse. ABA uses the functions of behavior to understand behavior and why it occurs. When you accurately identify the function of a behavior, you answer the question: What does this person “get” out of engaging in this behavior. This answer allows you to select function-based interventions to address the behavior.
What is positive reinforcement?
Positive reinforcement refers to the addition of a stimulus and negative reinforcement refers to the removal of a stimulus. This view of behavioral function is more detailed than the one described above and starts to dig more specifically into what stimulus is added (positive) or removed (negative) to strengthen the behavior (reinforcement).
How many functions of behavior are there?
Although traditional sources say there are 3-4 functions of behavior (access, escape, [attention] and automatic), there is a better way to conceptualize the functions of behavior. Cipani and Schock (2010) created a behavioral diagnostic system that expands on traditional models to help us understand behavior on a deeper level.
How to determine if a reinforcer is positive or negative?
First, identify if the reinforcer is positive or negative. Then, determine what type of reinforcer controls the behavior. Finally, determine if access to that reinforcer requires the presence of another person. Although this model requires 3 steps, it becomes fluid with some practice.
What is the difference between automatic and automatic behavior?
Escape includes behaviors that are negatively reinforced through escaping or avoiding an aversive stimulus. Automatic describes behaviors maintained by a pleasant sensory experience.
Can you hypothesize a function without a full analysis?
Without conducting a full analysis of the behavior, you can only hypothesize the function. In this example, the behavior is maintained by both the direct escape (delay of onset of the task) and socially-mediated escape (staff shortening the task) of a relatively lengthy task. The task might not actually take a long time to complete, ...
Choosing Effective Consequence Interventions
As we mentioned in the beginning, almost everything we do has a consequence. Consequences can be unintentional or planned. For the purpose of the rest of this article we will focus on planned consequences that are intended to change the behavior of a child.
Effectively Reinforcing Target Behaviors
In order for reinforcement to be effective, there are several factors to keep in mind:
Ethical Considerations of Reinforcement and Punishment
Positive reinforcement is often seen as the epitome of ethical practice in ABA. Similarly, punishment carries with it a stigma associated with control and abuse of power. In reality, these conditions occur naturally and neither are inherently good or bad. The distinction lies in the way these contingencies are applied by professionals.
Using Consequences to Change Behavior
Carefully planning consequences leads to positive behavior change. Use reinforcement alone whenever possible and use punishment with extreme caution and supervision. Carefully consider the risks and benefits of using any punishment procedure.

Recording Data For Analysis
Variability
- The variability of data relates to how different or “spread out” the scores are from each other. Take the two graphs below that show hypothetical data of the percentage of correct scores on a spelling test over 10 days for 2 children, Jane and Matt. The plotted data for Jane shows her percentage of correct spellings remains stable around 80%. The data for Matt’s percentage of c…
Level
- The level of the data relates to the “position” of the data set taken from the Y-axis. Look at the graphs below; in the first graph if the plotted data points fell into the top section they would have a “high level”, if they fell into the middle section they would have a “moderate level” and if they were in the bottom section they would have a “low level”. You could potentially separate the data level…
Trend
- The trend in the data is the “direction” it is going. For example, in the graph below, the first data set shows an “increasing trend” as the data points are “going up”. The second data set show a “decreasing trend” as the data points are “going down”. Finally, the third data set shows a “zero trend”because the data are not going up or down.
Why Use graphs?
- Graphs make it much easier to interpret and understand the data because they present the information in a visual format. For example , what can you draw from these set of numbers that recorded the percentage of correct spellings by a student over 14 school days: 45%, 46%, 52%, 48%, 58%, 61%, 64%, 75%, 70%, 78%, 75%, 80%, 84%, 90% You were probably able to tell that the p…
