Exam 10: Changing the Stimulus Control of a Behavior With Fading
Define errorless discrimination training.
Errorless discrimination training (errorless learning)is the use of a fading procedure to establish a stimulus discrimination so that no errors occur.
Define environmental prompt, and give an example that is not from this chapter.[
Environmental prompts are alterations to the physical environment in a manner that will evoke a desired behavior.For example, someone who is focusing on getting into shape may place pictures around his or her home of people lifting weights or doing other physical activity to serve as motivation or reminders for getting into shape.Any appropriate example is acceptable.
Define the four major categories of teacher-behavior prompts.
Give an example of each.
(a)Physical prompts-the teacher touches the student to guide him.(b)Verbal prompts- verbal hints or verbal cues that the teacher presents to evoke the correct response; (c)Gestural prompts-gestures or motions that the teacher makes (without touching the student)in order to evoke the desired behavior; (d)Modelling prompts-the teacher demonstrates (i.e., models)the correct behavior.Any appropriate examples are acceptable.
Why is establishing a stimulus discrimination without errors advantageous?
Define within-stimulus prompt, and give an example that is not from this chapter. Does your example involve a teacher-behavior prompt or an environmental prompt?
Give an example from this chapter in which the general training situation was faded.
Define extra-stimulus prompt, [and give an example that is not from this chapter. Does your example involve a teacher-behavior prompt or an environmental prompt?
How many reinforced trials should occur at any given fading step before the stimuli of that particular step are changed? (Hint: What suggestions were made in the examples in this chapter?)
Assume that you have an 18-month-old child who imitates the word chip.Describe in detail how you might use fading to teach your child to correctly identify a chip (e.g., a potato chip)when you point to it and ask, "What's that?"
Which of the prompt-removal procedures fit the definition of fading given at the beginning of this chapter, and which do not? Explain.
Give an example from this chapter in which the training situation remained constant but a specific stimulus dimension was faded.
Identify three stimulus dimensions along which fading occurred in the examples cited in the first two sections of this chapter.
