Serial and pop-out search times.

<p>Line diagram showing the mean (n = 33) visual search times for three distractor conditions (10, 20 or 30 distractors) for both serial (closed circles) and pop-out (closed squares) search tasks. Error bars show ± one standard error of the mean. Note that for some conditions, the error bars are not visible because one standard error was less than or equal to the symbol size.
