Crystallized intelligence—accumulated knowledge, vocabulary, and expertise—continues to grow into middle adulthood, so cognitive development as a whole tends to peak in middle adulthood.

1) Relevant knowledge points and concepts:
- Distinguish fluid vs. crystallized intelligence. Fluid intelligence (processing speed, novel problem solving) peaks earlier and declines with age. Crystallized intelligence (knowledge, vocabulary, expertise) improves with experience and often peaks later.
- Cognitive aging is domain-specific: some abilities peak earlier, others later. Developmental psychologists (e.g., Schaie, Baltes) describe these differing trajectories.

2) Step-by-step reasoning:
Step 1: Define adults stages: early adulthood (~20s–30s), middle adulthood (~40s–60s), late adulthood (60s+).
Step 2: Identify trajectories:
- Fluid abilities: fastest in early adulthood and begin gradual decline thereafter.
- Crystallized abilities: accumulate over decades and typically reach maximal performance in middle adulthood.
- Practical problem-solving, emotional regulation, and expertise improve with experience and are strong in middle adulthood.
Step 3: Integrate: Since “cognitive development” in general includes both knowledge and problem-solving benefits from life experience, the overall peak is in middle adulthood when crystallized abilities and expertise are high, even if some fluid components have started to decline.

3) Intermediate steps (conceptual, not numeric):
- Early adulthood = peak fluid speed.
- Middle adulthood = peak applied knowledge, vocabulary, expertise.
- Late adulthood = declines in many cognitive processes, though some wisdom/knowledge may remain.

4) Why the correct answer is correct:
Middle adulthood balances accumulated knowledge and intact cognitive processes sufficient to apply that knowledge effectively, producing the highest overall cognitive functioning across many real-world tasks.

5) Why other options are incorrect:
- Early adulthood: true for fluid speed but not for accumulated knowledge/expertise.
- After we cease to exist: nonsensical biologically and developmentally.
- Late adulthood: generally shows declines in several cognitive domains despite retained knowledge.

Conclusion: The best answer is in middle adulthood, which matches the provided correct answer.
