The role of verbal behavior in human learning: III. Instructional effects in children
Insights
Children
Area of Science:
- Psychology
- Developmental Psychology
- Behavioral Psychology
Background:
- Children's behavior is influenced by instructions.
- Self-instruction can shape behavior.
- Language plays a role in behavior regulation.
Purpose of the Study:
- To investigate the impact of self-instruction on children's behavior under a fixed-interval schedule.
- To examine age-related differences in response to instructions and self-instruction.
- To explore the role of language in mediating behavior.
Main Methods:
- Children from three age groups (2.5-4, 5-6.5, 7.5-9 years) participated.
- Participants were instructed to respond at high or low rates on a fixed-interval 40-s schedule.
- Children were trained to use spoken self-instructions aligned with experimenter instructions.
Main Results:
- High-rate instructions led to consistent high-rate responding across all ages.
- Low-rate instruction effects varied by age, with younger children showing less consistent low-rate behavior.
- Self-instruction training improved low-rate responding, particularly in older children, and enhanced interval estimation in the oldest group.
Conclusions:
- Language, specifically self-instruction, is a significant determinant of human behavior.
- The development of language-mediated self-regulation varies with age.
- Self-instruction can lead to adult-like behavioral control in children.
Abstract:
Lever pressing of children from three age groups (2(1/2) to 4, 5 to 6(1/2), and 7(1/2) to 9 years) could produce reinforcers according to a fixed-interval 40-s schedule: (1) Some were instructed to respond at a high rate, others at a low rate, and (2) they were subsequently taught to provide their own spoken self-instructions consonant with the earlier, experimenter-supplied instructions. All subjects who received high-rate instructions responded at a steady, high rate, which was maintained following self-instructional training. The effects of low-rate instructions were directly related to the age of the children. The two older groups produced low-rate patterns, with the oldest children responding at very low rates; effects were least noticeable in the youngest age group. Following self-instructional training, all three groups showed adult-like low-rate behavior and the oldest children showed an improved ability to estimate the interval length. The results provide further evidence of the importance of language as a determinant of human behavior.

Cognitive Learning
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
