N2  - Human response times fit a lognormal probability function, which poses severe constraints on the time a system designer must allow to accommodate a significant fraction of respondents; for example, 6 standard deviations for 95% confidence and 11 standard deviations for 99% confidence. When a human operates in series with machine elements, there may be no justification for demanding a quick response from the machine.<p />  <p>Language: en</p>
