Around 1975, which domains were highlighted as growing in AI and cognitive science?

• A. Developmental and computational linguistics
• B. Quantum computing
• C. Evolutionary biology
• D. Robotic control theory

Answer: (A)

The main idea being tested is which areas were expanding in AI and cognitive science around 1975. Developmental studies focused on how cognitive abilities unfold and learn over time, offering insights into learning mechanisms and how minds grow—key concerns for understanding intelligence in both humans and machines. Computational linguistics grew because language is a fundamental cognitive function, and turning linguistic theory into algorithms for parsing, understanding, and generating language became essential for building capable AI systems. This combination—how minds develop and how language can be processed computationally—stood out as the prominent growth areas of the era. Other domains like quantum computing or robotic control theory weren’t identified as the main growth focuses at that time, and while evolutionary biology has relevance to cognitive science, it wasn’t cited as a primary growth area in AI research circles around 1975.
