Define discrimination in learning.

Discrimination in learning refers specifically to the ability to differentiate between various stimuli and respond appropriately to them based on their differences. This concept is crucial in behaviorism, where organisms learn to respond to specific stimuli while ignoring others that are similar but not relevant. For example, a child may learn to discriminate between a bell that signals the end of recess and a bell that signifies a fire alarm; they react differently to each because they associate them with different outcomes.

In this context, the ability to recognize the nuances between stimuli and to respond accordingly is a fundamental aspect of learning processes. It highlights how individuals can develop specific responses based on learned experiences, which is essential for adapting behavior in varying environments or conditions.

The other choices do not accurately capture the essence of discrimination in learning. Remembering information pertains more to memory and retention rather than differentiation of stimuli. Ignoring distractions relates to focus and attention but falls outside the scope of distinguishing between stimuli. Performing an action without thought suggests automatic behavior or habits, which is a different concept related to impulse or reflexive actions rather than the deliberate differentiation involved in learning.
