Example of the 2-Back Working Memory Task

Figure 1 details the 0-Back and 2-Back conditions of the n-Back task. In both conditions, participants provide a yes/no response to each stimulus. The stimuli that should elicit a “yes” response are highlighted in bold above. In the 0-Back condition, participants were told to respond with a “yes” only if the “X or x” was presented. In the 2-Back condition, subjects were told to respond with a “yes” only if the stimulus matched one presented 2 stimuli prior, regardless of capitalization.
