      abstract     = {Using a dual-task paradigm, the present investigation
                      examined whether processes related to line orientation play
                      a critical role in the production of the Poggendorff
                      illusion. In Experiment 1, we assessed the magnitude of the
                      Poggendorff illusion under three different task conditions.
                      In the single-task condition, participants were asked to
                      report how they perceive the alignment of transversal lines
                      in the Poggendorff figure. In two different dual-task
                      conditions, the participants were asked to read aloud the
                      time displayed on a digital or analogue clock while also
                      performing the Poggendorff perception task. The method of
                      constant stimuli was used to calculate the point of
                      subjective equality (PSE) and bistability width values,
                      which represent illusion strength and perceptual
                      uncertainty, respectively. PSEs indicated that the magnitude
                      of the illusion did not vary between single, dual-analogue,
                      and dual-digital task conditions, which suggests that the
                      additional demands placed by the dual tasks had no effect on
                      the illusion strength. Perceptual uncertainty and
                      clock-reading errors were greater in the dual-analogue task
                      condition. Experiment 2 revealed that the analogue clockface
                      was more difficult to read than the digital clockface. Based
                      on these results, we conclude that having participants
                      perform a secondary task does not influence the magnitude of
                      the Poggendorff illusion.},
