Cambrige Gambling Task

The Cambridge Gambling Task (CGT) (Rogers et al. 1999) is a computerized measure of decision-making and risk-taking under explicit risk conditions. In each trial, participants are presented with a row of colored boxes (e.g., red and blue) in varying ratios and are asked to decide which color hides a token, after which they bet a proportion of their available points on their choice. The task provides indices of decision-making quality (selection of the more probable outcome), risk-taking (proportion of points wagered), and impulsivity (difference in betting between ascending and descending stake conditions), allowing assessment of risk evaluation and betting behavior independent of learning demands. This version of CGT is programmed in OpenSesame v.4.0 (Mathôt et al 2012).
