Schematic representation of tasks used and their conditions. Studies 1 and 2 featured the flanker, Stroop, go/no-go and stop-signal tasks. Study 3 featured the Posner cueing, SNARC and Navon tasks. Trials were presented intermixed in a randomized order. In the Go/no-go and Stop-signal tasks, visual stimuli were presented for a fixed duration of 1,250 ms (c.f. Verbruggen et al., 2008). In all other tasks, stimuli were presented until a response was given. An Inter-Stimulus Interval (ISI) of 750 ms was used in all tasks. Stimuli sizes are enlarged for illustration
