Syllabus: How Do Children Develop Language and Thought?
Introduce developmental regulation without treating a child’s behavior as a fixed capacity. Compare the review’s age patterns, neural proposals, and training evidence with the earlier distinctions among descriptions, mechanisms, and learning.
A question to consider. A practiced game improves after training. What evidence would justify claiming a change in flexible behavior beyond that game?
Why this reading
Children may know what to do yet struggle to organize their behavior accordingly. Zelazo and Carlson review the development of deliberate regulation across situations with different emotional and motivational demands. The article brings task performance, neural development, and possibilities for change into the same explanatory discussion.
Before you read
Executive function refers to processes involved in deliberately regulating thought and action, including maintaining information, inhibiting a response, and shifting between rules. Cool tasks are relatively emotionally neutral; hot tasks involve personally significant rewards or emotions. Both labels refer here to regulation. Plasticity means a capacity can change with experience, without specifying how broadly or durably that change transfers.
Read for
- Explain what makes a task relatively hot or cool. Avoid treating the distinction as two wholly separate systems or equating hot executive function with an uncontrolled emotional response.
- Separate age-related performance patterns, proposed neural mechanisms, and evidence from interventions. Which claims are observational and which use manipulated experience?
- Examine the training discussion. Distinguish improvement on a practiced task from transfer to other abilities, settings, and later outcomes.
Consider afterwards
- A program improves children’s scores on its practiced game. Specify a comparison group and an unpracticed outcome that would help determine whether the program improves more general regulation.
Editorial context
This 2012 review offers a useful developmental framework, but its optimistic training discussion should be read in historical context. Melby-Lervåg, Redick, and Hulme’s later meta-analysis found no convincing evidence of far transfer from working-memory training when compared with treated control groups. That conclusion concerns those programs, not every intervention or the possibility of developmental change. Associations between executive-function measures and later outcomes do not by themselves establish a causal pathway, and a single score is not a fixed description of a child.
