“…This effect, however, was modulated by ISI, F (1, 23) = 6.4, p < .05, η 2 p = .22, such that in the short ISI condition, the overestimation of the first stimulus compared to the second one was even larger than in the long ISI condition. Again, this is consistent with the findings of previous studies (e.g., Hellström & Rammsayer, 2004). …”

“…As outlined in the Introduction, there is previous evidence for a reversal of the Type B effect in duration discrimination when an even shorter standard duration (50 ms) than in the present experiments was employed, especially with relatively short ISIs (≤ 300 ms, Hellström & Rammsayer, 2004). In addition, the procedure to measure discrimination performance in this study differed in several ways from the one of the present experiments.…”

“…Interestingly, and contrary to IRM's predictions, there are some studies reporting reversed and thus positive Type B effects under particular circumstances (Hellström & Rammsayer, 2004;Hellström, 2003; for converging evidence, see also Hellström, 1979). Regarding duration discrimination, Hellström and Rammsayer (2004) report a positive Type B effect for very short duration stimuli, especially when presented with brief interstimulus intervals (ISI). It was suggested that processing of short durations might differ from processing of longer durations, especially when these are presented with longer ISIs.…”

“…Please note that axis breaks and scaling discontinuities for mean DL and P SE were employed to provide suitable scales for both standard durations and to grant comparability with the results of Experiment 2 displayed in Fig. 4 research had demonstrated a reversal of the Type B effect at short standard durations, especially when paired with short ISIs (Hellström, 2003;Hellström & Rammsayer, 2004). Therefore, Experiment 2 examined whether the Type B effect would be modulated by shortening ISI from 1,000 ms to 300 ms. For example, within IRM it seems plausible that the updating of the internal reference with the information from the first stimulus takes some time and therefore cannot be accomplished within a short ISI, before the first stimulus representation is masked by the representation of the second stimulus.…”

Effects of stimulus order on discrimination sensitivity for short and long durations

Previous studies have shown that discrimination sensitivity in 2AFC tasks depends on the presentation order of the standard and comparison stimulus. The present study examined whether this so-called Type B effect generalizes across different standard magnitudes. Therefore, Experiment 1 employed an auditory duration discrimination task with short (100 ms) and long (1,000 ms) standard durations and a constant interstimulus interval (ISI) of 1,000 ms. For both standard durations, a clear Type B effect emerged. In Experiment 2, discrimination sensitivity was assessed for short (300 ms) and long (1,000 ms) ISIs and a constant standard duration of 100 ms, in order to examine whether the Type B effect diminishes or even reverses when both stimuli are presented in rapid succession, as was suggested by previous studies. In the short, but not the long ISI condition, the Type B effect was virtually eliminated. Taken together, the present experiments suggest that the Type B effect is robust across standard magnitude, but diminishes when the time interval between both stimuli is reduced. This result pattern is discussed within the framework of the Internal Reference Model and the Sensation Weighting Model. It is also demonstrated that both models provide a quantitative account of the present results. In typical psychophysical tasks such as the two-alternative forced-choice (2AFC) task, participants are asked to discriminate between a fixed-magnitude standard stimulus s and a variable comparison stimulus c, whose magnitude can be lower, equal to or higher than the magnitude of the standard. In the temporal 2AFC task, these two stimuli are presented successively in one of two temporal orders, that is, sc and cs , to balance for potential effects of stimulus order on task performance. Researchers often disregard such order effects by aggregating data across stimulus order. However, if the observed data are analyzed separately for the two stimulus orders, order effects are commonly observed. For example, the order-conditional psychophysical functions observed in a typical 2AFC task might be shifted horizontally from the point of objective equality (i.e., a Type A order effect or time-order error), such that the magnitude of the first stimulus is either judged to be higher or lower than the magnitude of the second one. Theoretically, this might be the sign of a perceptual, decisional, or response bias, and has been extensively studied (cf. Eisler, Eisler, & Hellström, 2008). More important for the purpose of the present study, however, is the so-called Type B order effect (Ulrich 2010;Ulrich & Vorberg, 2009). This effect refers to the phenomenon that the spread of the order-conditional psychometric functions may differ with regard to stimulus order. Specifically, the difference limen (DL) is typically larger and thus discrimination sensitivity

“…Experiments investigating humans' memory for time in the duration-comparison procedure have a longer history and have been focused more on the phenomenon of explaining time-order errors (TOEs; Allan, 1977Allan, , 1979Hellström & Rammsayer, 2004;Jamieson, 1977;Jamieson & Petrusic, 1975a, 1975b, 1976Stott, 1935;Woodrow, 1935;Woodrow & Stott, 1936). In contrast to research with pigeons, the human studies have employed duration ranges on the order of milliseconds to prevent chronometric counting and duration pairs that prevent the identification of the correct response on the basis of the absolute duration of s f or c alone.…”

A major controversy in the field of prospective temporal information processing refers to the question of whether performance in various temporal tasks can be accounted for by the general assumption of an internal clock rather than by distinct, task-specific timing mechanisms. Therefore, the present study was designed to identify dimensions of temporal information processing. For this purpose, 120 subjects performed eight psychophysical temporal tasks. Correlational and principal factor analyses suggested a common pacemaker-based interval timing mechanism involved in duration discrimination, temporal generalization, and temporal order judgment. On the other hand, rhythm perception and perceived simultaneity/successiveness appeared to be controlled by task-specific processes unrelated to interval-based timing.
