      abstract     = {In time reproduction tasks, the reaction time of motor
                      responses is intrinsically linked to the measure of
                      perceptual timing. Decisions are based on a continuous
                      comparison between elapsed time and a memory trace of the
                      to-be-reproduced interval. Here, we investigate the
                      possibility that negative reproduction errors can be
                      explained by the tendency to prefer earlier over later
                      response times, or whether the whole range of possible
                      response times is shifted. In experiment 1, we directly
                      compared point reproduction (participants indicate the exact
                      time point of equality) and range reproduction (participants
                      bracket an interval containing this time point). In
                      experiment 2, participants indicated, in three separate
                      tasks, the exact time point at which the reproduction phase
                      was equal to the standard duration (point reproduction), the
                      earliest (start reproduction), or the latest moment (stop
                      reproduction) at which the exact time point of equality
                      might have been reached. The results demonstrate that the
                      bias towards earlier responses not only affects reproduction
                      of the exact time point of equality. Rather, even if the
                      decision threshold is changed in favor of late responses,
                      they exhibit a continuous shift towards negative errors that
                      increases with the length of the standard duration. The
                      findings are discussed in the context of the hypothesis that
                      systematic errors in time reproduction tasks reflect a
                      dimension-unspecific tendency towards earlier responses
                      caused by the psychophysical method rather than by a
                      time-specific perceptual distortion.},
