The monitor is blank for 1.5 s prior to the up coming letter is displayed. This supplies a duration of 2 s wherein the participant can respond to the go sign. A single check contains 176 trials wherein Just about every from the 4-letter stimuli will probably be offered Similarly frequently. A stop signal takes place in 48 trials throughout a take a look at. Members are needed to withhold any reaction in case a cease signal is presented. The task lasts about 10 min. Dependent variables are proportion of proper go responses and failed inhibitions on prevent trials and corresponding response times (Logan et al. 1984). The Quit response time (cease RT) to stop signal represents the approximated mean time required to inhibit a reaction.
