Instrument measuring choice reaction time and IQ differences
Diagram of a Jensen box, with the home button depicted in the lower center of the array. Participants are told to move their finger from the home button to one of eight additional response buttons when specific LED lights illuminate. This produces several measures of participant response time.
The Jensen box was developed by University of California, Berkeley psychologist Arthur Jensen as an experimental apparatus for measuring choice reaction time (RT) and individual differences in intelligence.[1]
