Hicks Law describes that increasing the number of options has what effect on response time?

• A. More options means a greater response time
• B. More options have no effect on response time
• C. Fewer options increase response time
• D. Increasing options reduces decision time

Answer: (A)

Hicks Law shows that choosing among more options takes longer because each extra option adds more information your brain must process to reach a decision. In practical terms, the response time increases with the number of choices, roughly following RT = a + b log2(n). This means doubling the number of options adds a constant amount of time, though the exact amount depends on how distinct the options are. So the overall pattern is that increasing options increases decision time, which is why the best answer states that more options mean greater response time. Options claiming no effect or a decrease in time contradict the law and the reasoning behind it.
