“…Indeed, based on his research on pitch and loudness discrimination, Doughty (1949) concluded that this method should not be used for assessing the PSE or the constant error (i.e., standard minus PSE) even though it may be suited to determine the difference threshold. However, the method of constant stimuli has been successfully used to investigate temporal phenomena related to perceived duration, for example, in studies on intentional binding (Nolden, Haering, & Kiesel, 2012), the temporal oddball effect (Birngruber, Schröter, & Ulrich, 2014;Tse, Intriligator, Rivest, & Cavanagh, 2004), the effects of stimulus repetition (Matthews, 2011), or the influence of global temporal contexts (Jones & McAuley, 2005). All these studies used comparison intervals that were symmetrically distributed around the physical standard duration, thereby avoiding a possible asymmetry effect.…”
