What type of discrimination training presents only one antecedent at a time during a trial?

The type of discrimination training where only one antecedent is presented at a time during a trial is known as successive discrimination. In this approach, the learner is exposed to individual stimuli one after another, allowing them to focus on each specific antecedent before determining the correct response. This method is effective in helping individuals learn to distinguish between stimuli based on their individual characteristics and the specific responses they elicit.

In contrast, other types of discrimination training, such as simultaneous discrimination, present multiple stimuli at the same time, requiring the learner to evaluate and choose among them simultaneously. Concurrent discrimination involves comparing different stimuli that are presented together, while isolated discrimination is not a standard term used in this context. Thus, the structure of successive discrimination allows learners to isolate and systematically respond to single antecedents, enhancing the clarity and effectiveness of the learning process.
