Abstract
This experiment aimed to determine whether the presentation of a temporal marker during the delay of reinforcement would increase choice response related to the greater magnitude and delay of reinforcement component (self-control), reducing the choices of the shorter delay and small magnitude component (impulsivity). Three values of delay interval have been investigated. Nine children were assigned to three conditions manipulated in the delay period: clock, no clock and blackout. Choices between self-control and impulsiveness component occurred on the computer screen producing points exchanged for gifts. Self-control was found in the first presentation of the smaller lag values in longer delay component, but not to larger values, regardless of the condition in effect. The time counter has not indicated to be a condition that increases the self-control. Such responses were related to the delay values.
