Mental chronometry is the scientific study of processing speed or reaction time on cognitive tasks to infer the content, duration, ...
A high level of S–R compatibility is typically associated with a shorter reaction time, whereas a low level of S-R compatibility tends to result in a longer reaction time, a phenomenon known as the Simon effect. The term "stimulus-response compatibility" was first coined by Arnold Small in a presentation in 1951. [1]
If the cue alternates, the executive switches tasks before processing the target. Switching takes time and creates a switch cost. Predicts equal Reaction times (RTs) for cue repetitions and task repetitions, and slower RTs for task alternations because this is the only condition where task switches actually occur. [10]
Given n equally probable choices, the average reaction time T required to choose among the choices is approximately: T = b ⋅ log 2 ( n + 1 ) {\displaystyle T=b\cdot \log _{2}(n+1)} where b is a constant that can be determined empirically by fitting a line to measured data.

The UConn men’s basketball coach and two-time national champion was caught on camera this week telling an official: "Don't turn your back on me; I'm the best coach in the (expletive) sport."
Simple reaction time correlates with general cognitive ability, [4] and there is some evidence that the slope of responding on the Jensen box does as well. [2] Ian Deary and colleagues, in a population-based cohort study of 900 individuals, demonstrated correlations between IQ and simple choice RTs between –0.3 and –0.5. [ 4 ]
