Explain Why Identifying Function Is So Important To Success

12 Hoursexplain Why Identifying Function Is So Important To Success

Identifying the function of target behaviors is crucial in the development of effective behavior intervention plans, particularly within the public-school system. The functional behavior assessment (FBA) serves as a foundational process that helps educators and behavior analysts understand why a student engages in specific behaviors, thereby enabling targeted and ethical interventions. Without a clear understanding of the function, interventions risk being ineffective or even counterproductive, as they may inadvertently reinforce the problematic behavior or overlook underlying needs.

The primary significance of conducting FBAs lies in the ability to tailor interventions that directly address the root cause of the behavior. For example, a student who engages in shouting during class might be doing so to seek attention, escape work, or fulfill sensory needs. If the teacher erroneously interprets the behavior as mere defiance and attempts punishment, it may exacerbate the situation or lead to other undesired consequences. Conversely, understanding that the behavior is functionally motivated allows for the implementation of proactive strategies, such as teaching alternative communication methods or modifying environmental factors, which significantly increases the likelihood of successful behavior change.

Research underscores the importance of FBAs in promoting positive behavioral outcomes and optimizing teacher effectiveness. Studies indicate that behavior interventions based on a thorough FBA are more sustainable and ethically sound, aligning with professional standards outlined by the Behavior Analyst Certification Board (BACB). Moreover, teachers equipped with skills to conduct FBAs can more effectively collaborate within multidisciplinary teams, ensuring interventions are appropriate, individualized, and respectful of student dignity.

For instance, when a student consistently refuses to complete assignments, an FBA might reveal that the behavior serves an escape function because tasks are perceived as too difficult or uninteresting. In this case, the teacher can modify tasks, teach coping skills, or provide breaks as appropriate, rather than using punitive measures. This targeted approach ensures the behavior change is meaningful and enduring, illustrating why identifying the function prior to intervention is essential.

Ethical Considerations for Assessments and Behavior-Change Interventions

Ethical considerations, as outlined in the BACB’s Ethics Code for Behavior Analysts, are vital when selecting and designing assessments. Code 2.13 emphasizes the importance of basing assessment methods on scientific evidence, ensuring that assessments are valid, reliable, and appropriate for the context and individual. It requires practitioners to consider cultural and linguistic backgrounds, as well as to seek informed consent. An ethically sound assessment process respects client autonomy, confidentiality, and minimizes discomfort or harm.

Similarly, Code 2.14 advocates for the ethically responsible design and implementation of behavior-change interventions. This includes selecting interventions that are evidence-based, individualized, and consistent with the client’s values and needs. Interventions should be continually monitored and adjusted based on data, ensuring they remain effective and ethically justified. Practitioners must also ensure that interventions do not unintentionally cause harm or diminish the dignity of the individual.

Functions of Behavior and Methods to Identify Them

The two broad categories of behavior function are (1) automatic or sensory and (2) social. Automatic functions refer to behaviors that are reinforced by internal stimuli or sensations, such as sensory stimulation, whereas social functions involve interactions with others for attention, escape, or access to tangibles. Through the FBA process, the probable function of a target behavior can be hypothesized by analyzing patterns in the data collected via indirect and direct assessments.

Indirect assessments include tools like parent or teacher interviews and questionnaires, which provide background information about circumstances surrounding the behavior. For example, a behavior checklist completed by teachers might suggest that the behavior occurs primarily during academic tasks, pointing towards an escape function. Another indirect approach is collecting scatterplots, which visualize the frequency and contexts of behaviors over time.

Direct descriptive assessments involve direct observation of the behavior in natural settings, often using ABC (antecedent-behavior-consequence) data collection or event recording. For example, an ABC recording might show that a student tantrums when asked to transition between activities, and the consequence is attention from peers or staff. Such data help hypothesize whether the function is social (attention or tangibles) or automatic.

Acquisition Programs: Shaping and Chaining

Acquisition of complex behaviors often involves techniques like shaping and chaining. Shaping is a process of reinforcing successive approximations toward a desired behavior. For instance, to teach a student to put on a coat, a teacher might reinforce the student when they hold the coat, then when they lift it, and eventually when they put it on their arms, gradually shaping the full behavior.

Chaining involves linking individual behaviors into a sequence to form a complex activity. There are three types of chaining procedures: forward chaining, backward chaining, and total task chaining. In forward chaining, teaching begins with the first step, and each subsequent step is added once the prior step is mastered. Conversely, backward chaining starts with the last step, prompting the individual to complete it first, which is particularly effective for fostering independence. Total task chaining teaches all steps simultaneously, prompting the individual through the entire sequence until mastery.

For example, in teaching a student to brush their teeth, total task chaining might involve guiding the student through each step of the brushing process—from picking up the toothbrush, applying toothpaste, brushing, rinsing, to putting away the toothbrush—until they can perform the entire sequence independently. A task analysis—a breakdown of steps—supports this process by clearly delineating each component. Shaping can be used within this process for individual steps, such as reinforcing the first attempt to hold the toothbrush correctly, then progressively reinforcing more precise actions.

Reduction Programs: Differential Reinforcement

Reduction programs focus on decreasing problematic behaviors through techniques like differential reinforcement, which involves reinforcing desirable behaviors while withholding reinforcement for undesirable ones. Differential reinforcement of alternate (DRA) involves reinforcing an alternative, appropriate behavior instead of the problematic behavior. For example, teaching a student to request a break instead of engaging in disruptive behavior by reinforcing the requesting behavior.

Differential reinforcement of other (DRO) involves providing reinforcement contingent on the absence of the problematic behavior during a specified interval. For instance, delivering praise when a student refrains from tantruming for a set period.

Differential reinforcement of incompatible (DRI) reinforces a behavior incompatible with the target behavior. For example, reinforcing hand-raising instead of calling out, as the two behaviors cannot occur simultaneously. These methods are effective tools in reducing problematic behaviors while promoting functional alternatives.

Generalization and Maintenance

Generalization refers to the transfer of acquired skills across different environments, situations, or behaviors, while maintenance involves sustaining behavior change over time. Both are critical to ensuring that interventions produce lasting improvements beyond the training context.

Programming for generalization and maintenance is essential because skills learned in controlled settings often do not automatically transfer to everyday life. Techniques to promote generalization include varying the training setting, incorporating multiple instructors, and using natural reinforcement contingencies. For instance, practicing social skills in different social scenarios prepares students for real-world interactions. To ensure maintenance, ongoing reinforcement, booster sessions, and self-monitoring strategies can be employed. For example, periodically reviewing communication skills or academic content, even after initial mastery has been achieved, reinforces retention and generalization.
