Fixed-ratio and fixed-interval schedule control of matching-to-sample errors by children

Area of Science:

• Behavioral Psychology
• Child Development

Background:

• Operant conditioning principles are well-established in animal behavior.
• Understanding schedule control in children is crucial for educational and therapeutic applications.

Purpose of the Study:

• To investigate how different reinforcement schedules influence matching-to-sample performance in children.
• To compare children's responses to reinforcement schedules with those of nonhuman animals.

Main Methods:

• Nine children (ages 4-7) completed matching-to-sample tasks under fixed-ratio, fixed-interval, variable-ratio, and variable-interval schedules.
• Three delay conditions were used: simultaneous, zero-delay, and 2-second delay.
• Error patterns and accuracy were analyzed across conditions.

Main Results:

• Fixed-ratio schedules produced systematic error distributions in most children, with errors concentrated after reinforcement.
• Fixed-interval schedules also produced error distributions, peaking in the second quarter of the interval.
• Variable-ratio and variable-interval schedules resulted in lower accuracy and no systematic error patterns.

Conclusions:

• Schedule control of complex operants in children parallels findings in nonhuman animals.
• Reinforcement schedule type significantly impacts error patterns in children's learning.
• Children exhibit predictable error distributions under specific reinforcement schedules, similar to animal models.
