Question: Touching a picture of pizza only results in reinforcement after the instruction, “touch pizza” is provided describes which type of discrimination?
One of the most important skills for children with autism spectrum disorder (ASD) is to learn how to discriminate between different stimuli and respond appropriately. Discrimination training is a type of teaching procedure that involves reinforcing correct responses to specific stimuli and extinguishing incorrect responses to other stimuli. For example, a child may learn to touch a picture of a pizza only when the teacher says "touch pizza", and not when the teacher says "touch apple" or shows a picture of a banana. This is an example of conditional discrimination, which means that the correct response depends on the presence of another stimulus (the instruction).
Conditional discrimination is different from simple discrimination, which involves reinforcing correct responses to one stimulus regardless of other stimuli. For example, a child may learn to touch a picture of a pizza whenever it is presented, regardless of what the teacher says or shows. In this case, the picture of the pizza is the only stimulus that controls the child's behavior.
Conditional discrimination is more complex and challenging than simple discrimination, but it is also more useful and adaptive in everyday life. Conditional discrimination allows us to adjust our behavior according to different situations and contexts, such as following rules, instructions, or social cues. Conditional discrimination also enables us to learn abstract concepts, such as categories, relations, or functions.
There are different types of conditional discrimination, depending on the nature of the stimuli involved. One common type is matching-to-sample (MTS), which involves presenting a sample stimulus (such as a word or a picture) and asking the learner to select the matching stimulus from an array of comparison stimuli. For example, the teacher may show a picture of a pizza and ask the child to touch the word "pizza" among other words. Another common type is listener responding (LR), which involves presenting a verbal stimulus (such as a word or a sentence) and asking the learner to perform an action related to that stimulus. For example, the teacher may say "touch pizza" and ask the child to touch a picture of a pizza among other pictures.
The example given in the keywords - touching a picture of pizza only results in reinforcement after the instruction, "touch pizza" is provided - describes which type of discrimination? The answer is listener responding (LR), because the correct response (touching the picture of pizza) depends on the verbal stimulus (the instruction "touch pizza") provided by the teacher.
