Maya is participating in a new reading program designed to enhance her reading fluency. In this program, she is given a list of books to read, each with an associated quiz to test her understanding after finishing the book. To motivate the students, the program includes a special reward system: If a student completes the quiz within two days of finishing the book, they receive bonus points that can be exchanged for prizes at the end of the month. However, if a student takes the quiz after the two-day period, they only receive the standard points for quiz completion, without any bonus. This system is an example of:

Which schedule is likely to produce a scallop effect, where response rate gradually increases as the time for reinforcement draws near?

The changing criterion design focuses on behavior improvements through adjustments

Shaquin has been participating in a behavior modification program to improve his study habits. Initially, his behavior analyst set up a fixed ratio (FR) schedule where Shaquin would receive a small reward after completing just two homework assignments. Encouraged by his progress, the behavior analyst gradually increased the ratio requirement. However, as the requirement reached ten assignments per reward, Shaquin started to show signs of frustration, procrastination, and eventually reduced the number of assignments he completed. This decrease in Shaquin’s homework completion is most indicative of:

During a summer reading program, Sarah’s local library implements a new reinforcement strategy to encourage children to read more books. To earn a special reward, a child must meet both of the following criteria within a four-week period: read at least 20 books (response requirement) and attend at least four weekly reading group sessions (time-based requirement). This strategy is an example of which type of reinforcement schedule?

Jeremy has been participating in a new online language learning program where he earns points for each lesson completed. The program is designed to gradually increase the challenge: initially, Jeremy needs to complete just one lesson to earn 10 points. After earning the first 10 points, he must complete two lessons for the next 10 points, then three lessons for the next, and so on. This pattern of increasing the number of lessons required for the same reward continues as Jeremy progresses through the program. This method of adjusting the lesson completion requirement for rewards is an example of:
