Participants are asked to press the SPACEBAR if any digit other than 3 is presented and to withhold the response The digit disappears after a short while and is replaced with a mask (circle with an X). Participants are presented with a single digit 1-9 in the middle of the screen in varying fontsizes. n_mindwanderingprobe = true (default is false) To run the probe addition, go to section Editable Parameters and set The mindwandering probe in the additional script. The code is provided in helper script "SART_MindWanderingProbeAddition.iqx". !NOTE: This script includes an optional "Mindwandering Probe" addition for the SART.iqx.
