AFFGO: Affective Go-NoGo Task


Go-NoGo task for emotional processing and impulse control.

This is a Go-NoGo task in which the participant only has to respond to stimuli with a certain affective load (target emotion). A reaction should be refrained with other stimuli (distractor emotion). There are 3 categories of stimuli (afraid, happy and neutral, the labels “afraid” and “happy” can also be replaced with “negative” and “positive”, respectively). The task can be set to Pictorial, and to Verbal. In the pictorial version, standard images are used from the IAPS database (International Affective Picture System by Lang et al., 1999). Here, images have been evaluated for valence (pleasant, unpleasant, neutral) and arousal value (intensity). The verbal version uses words from the CELEX database (Max Planck Institute for Psycholinguistics). It is possible to define different stimuli as well.

A response can be given by pressing the space bar, the mouse, the touch screen or the optional button box. Up to 6 blocks with trials can be defined in advance, with possibly different categories of stimuli (in 3 categories there are 6 possible combinations). An FF (full factorial) design is also possible whereby the 6 different blocks are presented in random order. Per block it is also possible to vary the ratio between number of target trials and distractor trials (default 2 : 1). A short practice session precedes each block, in which it is also possible to view all stimuli to be used in the block. In the report, the average RT and the error rate are given per block. Normative information is based on data from normal volunteers and from TBS patients, and from young people aged 12-18 years. An interpretation of the results can be generated.

An English language version is available.

This task is also part of the package forMinds, which is used at the Pompe Foundation. Order is on condition that agreements are made with the Pompe Foundation about the use of the task.
