Questions and Answers

Patrick's toilet training involved prompting and reinforcement, eventually fading prompts as independence increased. Which of the following BEST describes this process?

  • Establishing operation

  • Transfer of stimulus control (correct)
  • Negative reinforcement

Flashcards

Fading Prompts

The process of gradually reducing assistance (prompts) to allow independent performance of a behavior.

Antecedent manipulation

The manipulation of environmental events by the teacher by closing the latch on Fiona's lunchbox and placing it in front of Fiona.

Contingency

The relationship or dependency between a behavior and the events that precede and follow that behavior.

Functional Relationship

Exists when changes in one event (dependent variable) are reliably produced by manipulations of another event (independent variable).

Study Notes

  • The exam contains 272 questions.

Toilet Training Program Example

  • Patrick is in a toilet training program with Moira as his trainer.
  • Initial sessions involved Moira prompting Patrick to use the toilet, followed by edibles and praise for correct voiding.
  • Moira gradually faded prompts as Patrick started using the toilet independently.
  • This process is best described as a transfer of stimulus control.

Lunchbox Example

  • Fiona cannot independently open her lunchbox.
  • The teacher closes the latch and places the lunchbox in front of Fiona.
  • The teacher has manipulated the prompt.

Dependency Between Response and Stimuli

  • The dependency between a response and the stimuli that precede and follow it is referred to as a contingency.

Functional Relationship

  • A functional relationship exists when two events consistently co-vary.

Self-Injurious Behavior Example

  • Larry engages in self-injurious behavior (scratching) maintained by automatic reinforcement, leading to abrasions.
  • The behavior analyst has Larry wear long-sleeved shirts to reduce the behavior.
  • This is an example of extinction.

Generalization

  • A person engages in target behaviors in environments different from the original training environment.
  • This is a demonstration of stimulus generalization.

Dentist Office Example

  • Terry's heart rate increases and he sweats upon entering the dentist's office due to its association with unpleasant dental work.
  • He is reluctant to make appointments.
  • His physical symptoms are an example of respondent behavior.

Operant Conditioning

  • The defining feature of operant conditioning, in contrast to respondent conditioning, is that the probability of behavior changes because of changes in consequences.

Echoic Behavior

  • Echoic behavior is controlled by a verbal stimulus.
  • The response matches that stimulus.
  • The reinforcer is non-specific.

Communication Training Session Example

  • A behavior analyst says to a child, "Say your name."
  • The child says, "Sarah," and the analyst delivers a reinforcer.
  • The behavior analyst's statement was a prompt.

Tact Behavior

  • Tact behavior is controlled by a non-verbal stimulus.
  • The reinforcer for tact behavior is non-specific.

Favorite Food Example

  • Mr. Myers asks Susan what her favorite food is.
  • Susan answers, "Spaghetti."
  • This is an example of an intraverbal.

Contingency-Shaped Behavior

  • Contingency-shaped behavior is established as the result of a person's experience.

Stir-Fry Vegetables Example

  • Katie touched a hot pan while learning to stir-fry vegetables and now refuses to make them.
  • Her refusal is a result of unconditioned punishment.

Descriptive Assessment

  • A descriptive assessment generally includes development of hypotheses, gathering of historical and current data, and graphic representation of data.
  • It does NOT include manipulation of variables.
