PSYC4005 builds the procedural toolkit that turns ABA principles into clinical action. After PSYC4003 (measurement) and PSYC4004 (assessment), this course addresses the third leg of the practice tripod: what specific, evidence-based procedures does a behavior technician or assistant behavior analyst actually implement once a target behavior is defined and its function is understood? The course covers the core skill-acquisition and behavior-reduction procedures that make up the daily work of ABA practice.
Core procedure categories
| Category | Purpose | Key Procedures |
|---|---|---|
| Skill acquisition | Teach new behaviors not currently in the repertoire | Shaping, chaining (forward, backward, total task), prompting and fading, discrete trial training |
| Reinforcement-based behavior reduction | Decrease problem behavior while building alternatives | DRA, DRI, DRO, NCR (noncontingent reinforcement) |
| Extinction-based procedures | Remove the reinforcer maintaining problem behavior | Extinction, response blocking, extinction bursts and how to manage them |
| Antecedent strategies | Prevent problem behavior before it starts | Demand fading, choice provision, environmental enrichment, motivating operation manipulation |
What PSYC4005 covers
Prompting and fading procedures teach the technician-level skill of providing just enough assistance to evoke the correct response, then systematically removing that assistance so the learner becomes independent. The prompt hierarchy moves from most-to-least intrusive (physical, then gestural, then verbal, then visual) or least-to-most intrusive, depending on the learner and the skill. PSYC4005 builds the ability to select an appropriate prompt level, fade it according to a planned schedule, and recognize prompt dependency when fading is not occurring as planned.
Differential reinforcement procedures are introduced as the preferred, least restrictive approach to reducing problem behavior. Differential Reinforcement of Alternative behavior (DRA) reinforces a specific replacement behavior that serves the same function as the problem behavior. Differential Reinforcement of Incompatible behavior (DRI) reinforces a behavior that cannot physically occur at the same time as the problem behavior. Differential Reinforcement of Other behavior (DRO) reinforces the absence of the problem behavior for a specified period. Each has trade-offs: DRA is generally preferred because it teaches a functional replacement skill, while DRO can inadvertently reinforce whatever behavior happens to occur during the interval.
Writing a procedure selection paper or prompting hierarchy plan?
Our ABA writers apply skill-acquisition and behavior-reduction procedures with the procedural precision BCaBA coursework requires.
Key topics you write about in PSYC4005
- Shaping: successive approximations toward a terminal behavior, differential reinforcement of closer approximations
- Chaining: task analysis, forward chaining, backward chaining, total task presentation
- Prompting and fading: prompt hierarchies (most-to-least, least-to-most), time delay, stimulus fading, prompt dependency
- Discrete trial training: trial structure (SD, response, consequence, intertrial interval), mass trials vs. distributed practice
- Differential reinforcement: DRA, DRI, DRO, NCR — selecting the right procedure for the function and the goal
- Extinction: planned ignoring, extinction bursts, spontaneous recovery, resistance to extinction
- Antecedent-based strategies: demand fading, choice, environmental enrichment as proactive behavior reduction
- Generalization and maintenance: programming behavior change to transfer beyond the training setting
Common writing assignments
Procedure selection and justification paper
Given a case scenario with a defined target behavior and its function, students select an appropriate skill-acquisition or behavior-reduction procedure and justify the choice based on the function, the learner's current skill level, and the least-restrictive-alternative principle.
Task analysis and chaining plan
Students break a multi-step skill (handwashing, making a sandwich, tying shoes) into a written task analysis and design a chaining procedure (forward, backward, or total task) with a rationale for the chosen approach.
Choosing between DRA, DRI, and DRO
- DRA: preferred when a clear, teachable replacement behavior serves the same function as the problem behavior
- DRI: useful when a physically incompatible behavior is readily available and reinforceable
- DRO: a fallback when no clear alternative behavior is identifiable yet; requires careful monitoring to avoid reinforcing other undesired behavior
How GradeEssays helps with PSYC4005
GradeEssays supports BCaBA-track students with procedure selection papers, task analysis and chaining plans, prompting hierarchy designs, and PSYC4005 writing. When you share your case and Capella's rubric, your writer produces procedurally precise ABA behavior change writing. All work is original and delivered with time for your review.

Frequently asked questions
Forward chaining teaches the first step of a task analysis first, requiring the learner to complete it independently before help is provided on remaining steps (which are completed by the trainer or with full assistance). Backward chaining teaches the last step first, with the trainer completing all earlier steps and the learner completing the final step independently. Backward chaining can be particularly reinforcing because the learner experiences "finishing" the task at every trial, even early in training.
Prompt dependency occurs when a learner comes to rely on a prompt and fails to respond correctly once it is removed, often because the prompt was faded too quickly, was too salient, or because differential reinforcement was not used to favor independent responses over prompted ones. Avoiding it requires a planned, gradual fading schedule, reinforcing independent (unprompted) responses more richly than prompted ones, and regularly probing for independent responding rather than continuing to prompt indefinitely.
An extinction burst is a temporary increase in the frequency, intensity, or duration of a behavior when reinforcement is first withheld, before the behavior decreases. It matters clinically because caregivers and even practitioners may interpret the burst as evidence the procedure is failing and abandon it prematurely, when in fact the burst is an expected part of the extinction process. Anticipating and explaining extinction bursts in advance, and having a safety plan if the behavior poses risk, is part of responsible procedure selection.
DRA teaches and reinforces a specific, functional replacement behavior that serves the same purpose as the problem behavior, building a skill the learner can use going forward. DRO simply reinforces the absence of the problem behavior during an interval, regardless of what else the learner is doing, which means it can inadvertently reinforce other behaviors (including other undesired ones) and does not teach a functional replacement. DRA is therefore usually the more clinically useful and durable approach when a suitable replacement behavior can be identified.
