Final answer:
Positive reinforcement serves as a teaching signal for learning stimuli and behavior associated with reward.
Step-by-step explanation:
The teaching signal for learning stimuli and behavior associated with reward is positive reinforcement. Positive reinforcement involves adding a desirable stimulus to increase a behavior. For example, if a student is rewarded with praise or good grades for studying, they are more likely to continue studying in the future.
Another example is the experiment conducted in Dallas where second-grade students were paid $2 for reading a book and passing a quiz. This form of positive reinforcement significantly increased their reading comprehension.
Positive reinforcement is a powerful teaching tool as it motivates individuals to engage in desired behaviors by associating them with rewards.
