This dataset includes skin conductance response (SCR) measurements for each of 22 healthy unmedicated participants (11 males and 11 females aged 24.7+/-4.5 years) participating in a visual detection task. Participants are requested to react by a keypress to a target visual stimulus (a red cross) embedded in a stream of distractors (white numbers). Stimuli are presented during 200ms and are spaced by a 800ms blank interval. A baseline period with distractors but no targets concludes the experiment. (This is in contrast to the methods description in Bach et al. (2010), according to which the baseline period was randomly either in the beginning or at the end of the experiment. This discrepancy was caused by an error in the code that controlled the experiment presentation.)
