Hick's law for choice reaction time: A review
Research-assisted source review
- What it supports
- The relationship between set size and choice reaction time remains influential, but its slope and interpretation depend on how naturally signals map to responses, experience with the task, very large sets and what happened on recent trials.
- Where it may not transfer
- A narrative review does not provide one pooled effect for interface outcomes. Its HCI relevance is an informed extension from reaction-time research, not evidence that fewer navigation or commercial options always improve the experience.
