RBT Practice Test 2 — Questions and Answers
Question 1: What type of consequential operation occurs when a stimulus is added to theenvironment and results in a decrease in behavior over time?
- Positive Reinforcement
- Negative Reinforcement
- Positive Punishment (Correct answer)
- Negative Punishment
Correct answer: Positive Punishment
Positive punishment involves the *addition* of a stimulus to the environment *following* a behavior. If this addition results in a *decrease* in the future likelihood of that behavior, it is defined as positive punishment. The term 'positive' refers to adding something, and 'punishment' refers to the decrease in behavior.
Question 2: Mass trials are represented by which of the following?
- A therapist continuously shows the same SD to a student, encouraging the same specific conduct trial after trial until the student completes 5 requested right trials in a row. (Correct answer)
- A teacher hands a student a worksheet with 100 problems on it and tells them "You have 3 minutes. Make an effort!"
- During a clinical trial, a scientist mass manufactures hundreds of samples of a new chemical.
- All of the above.
Correct answer: A therapist continuously shows the same SD to a student, encouraging the same specific conduct trial after trial until the student completes 5 requested right trials in a row.
Mass trials are a discrete trial teaching (DTT) strategy where the same discriminative stimulus (SD) is presented repeatedly to a learner, prompting the same target response multiple times in a row. This method is used to establish new skills or increase fluency by providing numerous opportunities for practice and reinforcement of a single target behavior. The goal is to build strong stimulus-response associations.
Question 3: What does the term "response latency" mean?
- The delay of time between the SD and a reinforcer / punisher.
- The delay of time between a stimulus and a given response. (Correct answer)
- A trial's length.
- The time it takes for a behavior to begin and then stop.
Correct answer: The delay of time between a stimulus and a given response.
Response latency is a temporal dimension of behavior measurement that refers to the time elapsed from the presentation of a stimulus (e.g., an instruction or SD) to the initiation of the target response. It measures how quickly a behavior begins after a cue. For example, if a teacher says "touch nose," latency would be the time until the student starts to move their hand towards their nose.
Question 4: Reinforcers that get their reinforcing properties by combining with another reinforcer are referred to as _________________.
- Paired Items
- Unconditioned
- Negative Reinforcers
- Conditioned (Correct answer)
Correct answer: Conditioned
Conditioned reinforcers, also known as secondary reinforcers, are stimuli that acquire their reinforcing properties through association with primary (unconditioned) reinforcers or other established conditioned reinforcers. For example, praise or money are not inherently reinforcing but become so because they have been paired with access to unconditioned reinforcers like food or comfort.
Question 5: What are the four behavioral functions?
- Sensory Overload, Non-Compliance, Aggression, and Compliance
- Toys, Edibles, Praise, and Aversion
- Sensory, Escape, Attention, and Tangibles (Correct answer)
- None of the above
Correct answer: Sensory, Escape, Attention, and Tangibles
The four primary functions of behavior, often remembered by the acronym SEAT, are Sensory (automatic reinforcement), Escape (avoiding or terminating aversive stimuli), Attention (gaining social interaction), and Tangibles (accessing desired items or activities). Understanding these functions is crucial for conducting functional behavior assessments and developing effective interventions.
Question 6: Which of the following are examples of preference evaluations used by behavior analysts to identify lists of appetitive stimuli?
- Multiple Free Pick Test (MFPT)
- Multiple Stimulus Without Replacement (MSWO) (Correct answer)
- Mixed Stimuli Assessment Battery (MSAB)
- Many Stimulus Replacement (MSR)
Correct answer: Multiple Stimulus Without Replacement (MSWO)
The Multiple Stimulus Without Replacement (MSWO) is a systematic preference assessment procedure where an array of stimuli is presented, and the learner selects one. The selected item is then removed from the array, and the remaining items are re-presented. This process continues until all items are chosen, creating a hierarchy of preferences and effectively identifying a ranked list of preferred items.
Question 7: Which of the following types of Continuous data collecting methods are you familiar with?
- Counting
- Frequency (Correct answer)
- Single Interval
- Whole Interval
Correct answer: Frequency
Frequency is a continuous measurement method that involves counting every instance of a behavior within a specific observation period. Unlike discontinuous methods, it captures every occurrence, providing a complete count of how often a behavior happens. Other continuous measures include duration, latency, and interresponse time, all of which record every instance or aspect of the behavior.
Question 8: Which antecedent raises or diminishes a consequence's value?
- Motivating Operation (Correct answer)
- Establishing Operation
- Abolishing Operation
- None of the above
Correct answer: Motivating Operation
A Motivating Operation (MO) is an environmental event that alters the current value of a stimulus as a reinforcer or punisher, and also alters the current frequency of all behavior that has been reinforced or punished by that stimulus. For example, being deprived of food (an MO) makes food more valuable as a reinforcer and increases behaviors that have previously led to food.
Question 9: Skinner defined Verbal Behavior in terms of _______________ over ________________.
- Negative Reinforcement, Positive Reinforcement
- Positive Reinforcement, Negative Reinforcement
- Form, Function
- Function, Form (Correct answer)
Correct answer: Function, Form
B.F. Skinner's analysis of verbal behavior emphasized the *function* of language (why a person speaks) rather than its *form* (the grammatical structure or topography of the words). He categorized verbal operants based on their controlling variables and the consequences they produce, highlighting the environmental factors that maintain verbal behavior. This functional approach allows for effective teaching of communication skills.
Question 10: After the learner performs the final step in the chain, which kind of chaining results in the learner being reinforced?
- Sideways Chaining
- Backwards chaining (Correct answer)
- Forwards chaining
- Total task presentation
Correct answer: Backwards chaining
In backwards chaining, the trainer completes all steps of a task analysis except for the last one. The learner is then prompted to perform only the final step, and reinforcement is delivered immediately upon successful completion. This method ensures that the learner experiences immediate reinforcement upon completing the final, natural step of the chain, which can be highly motivating.
Question 11: What must the client or the person who makes decisions for the client, such as a parent or guardian, do if punishment is to be used?
- Have already attempted positive reinforcement
- Give informed consent (Correct answer)
- Trust that it will work
- Attend workshops on how to apply punishment effectively.
Correct answer: Give informed consent
The use of punishment procedures in ABA requires careful consideration and ethical safeguards. Before implementing any punishment, the client or their legal guardian must provide informed consent. This means they fully understand the procedure, its potential risks and benefits, and alternative interventions, ensuring respect for autonomy and protecting the client's rights.
Question 12: When gathering discontinuous data, which device are you most likely to use?
- Computer
- Stopwatch (Correct answer)
- Video camera
- Mobile phone
Correct answer: Stopwatch
Discontinuous data collection methods often involve measuring behavior within specific intervals or at specific moments. A stopwatch is commonly used for interval recording (e.g., partial interval, whole interval) or momentary time sampling, where the presence or absence of a behavior is recorded during or at the end of predetermined time intervals. It helps precisely time these observation periods.
Question 13: What is one of the most significant advantages of having permanent product data?
- It's less difficult to take than other kinds of data.
- No direct observation of behavior is required. (Correct answer)
- You are free to ignore all behavior.
- None of the above
Correct answer: No direct observation of behavior is required.
Permanent product measurement involves measuring the tangible outcomes or effects of a behavior, rather than observing the behavior directly as it occurs. This is a significant advantage because it allows data to be collected even when the observer is not present, making it efficient and less intrusive. Examples include counting completed assignments or tallying broken items.
Question 14: Which DR procedure is based on time?
- DRA
- DRI
- DRO (Correct answer)
- All of the above
Correct answer: DRO
Differential Reinforcement of Other behavior (DRO) is a time-based procedure where reinforcement is delivered when the target problem behavior has *not* occurred for a specified interval of time. If the behavior occurs during the interval, the timer is reset. This procedure aims to decrease a target behavior by reinforcing its absence over a set period.
Question 15: Which differential reinforcement procedure requires reinforcing behavior that is physically incompatible with the goal behavior?
- DRI (Correct answer)
- DRA
- DRO
- DRH
Correct answer: DRI
Differential Reinforcement of Incompatible behavior (DRI) involves reinforcing a behavior that cannot physically occur at the same time as the problem behavior. For example, reinforcing a child for keeping their hands in their pockets makes it physically impossible for them to hit someone. This procedure directly competes with the target behavior, making it an effective reduction strategy.
Question 16: ____________________ occurs when the characteristics of a relevant stimulus are changed or amplified in order to improve the chance of a target behavior happening.
- Exaggerated prompting
- Most to least prompting
- Stimulus prompting (Correct answer)
- Positional prompting
Correct answer: Stimulus prompting
Stimulus prompting involves altering the discriminative stimulus (SD) or adding a new stimulus to make the correct response more likely. This can include exaggerating a feature of the stimulus, changing its position, or adding cues like highlighting. The goal is to guide the learner towards the correct response by making the SD more salient or easier to discriminate.
