“…We hypothesized that, because time, space and magnitude rely on common mechanisms, a discrepancy in numerical magnitude should directly impact perceived duration; this hypothesis was confirmed. Additionally, the directionality of the sequence (increasing vs. decreasing) did not modulate the effect, replicating previous kappa effect studies (Alards-Tomalin et al, 2013;Henry & McAuley, 2009). This provides convergent support for our view that the present results represent a variant of the kappa effect based on a manipulation of a phenomenological, distance (i.e., the space delineated on a mental number/magnitude line).…”

The relative magnitude (or intensity) of an event can have direct implications on timing estimation. Previous studies have found that greater magnitude stimuli are often reported as longer in duration than lesser magnitudes, including Arabic digits (Xuan, Zhang, He, & Chen, 2007). One explanation for these findings is that different quantitative dimensions (size, intensity, number) are processed and represented according to a common analog magnitude system (Walsh, 2003). In the current study, we examined whether there were commonalities in how people judge the intervals of time occurring between discrete stimuli of different magnitudes across a variety of quantitative dimensions, which included number, size, and color saturation. It was found that duration judgments increased systematically as the overall magnitude difference between sequentially presented stimuli increased. This finding was robust against manipulations to the direction of the sequence, or whether the sequence followed ordered (continuous) or nonordered (discontinuous) pattern trajectories.

“…The kappa effect is explained by the imputed velocity model, positing the constancy of motional speed or velocity (Alards-Tomalin et al, 2013;Henry and McAuley, 2009;Jones and Huang, 1982;Sarrazin et al, 2004;ten Hoopen et al, 2008). According to this model, the kappa effect (three stimuli) pattern is perceived as consisting of a single object appearing three times, instead of three discrete objects appearing successively.…”

The Kappa Effect With Only Two Visual Markers

The kappa effect is a spatiotemporal illusion where duration is overestimated with the increase of space. This effect is typically demonstrated with three successive stimuli marking two neighboring empty time intervals, and the classical imputed velocity model, in principle, does not help to predict any spatial effects when only two stimuli, marking single intervals, are presented on each trial. We thus conducted three experiments, examining requirements for the occurrence of the kappa effect with only two visual stimuli. An interstimulus interval between the two stimuli was 217 (short) or 283 ms (long), and participants categorized the presented interval as 'short' or 'long'. The key finding is that participants tended to respond 'short' more frequently than 'long' when both stimuli were delivered from the same location, whereas the relative frequency of 'long' responses was increased when the two stimuli were delivered from different locations in most directions (i.e., horizontally, vertically, diagonally; Experiment 1). This kappa effect clearly occurred when each stimulus was located 8°a part from the fovea in visual angle, but it was reduced when each stimulus was further deviated from the fovea, regardless of whether the two stimuli were presented in the vertical or the horizontal direction (Experiments 2 and 3). Moreover, increasing the spatial distance between the two stimuli from 15 to 30 cm magnified the effect only in a limited condition (Experiment 3). Implications of these results were discussed in terms of the Bayesian model predicting the effects of spatial acuity.

“…Notably, perceived time is not necessarily a precise reflection of physical features (veridical percepts), but can be influenced by contextual factors such as visual space (Jones and Huang, 1982), sound intensity (Alards-Tomalin et al, 2013), or pitch (Shigeno, 1986;Boltz, 1998Boltz, , 2011Henry and McAuley, 2009). In particular, the pitch trajectory of a stimulus has been shown to distort perceived stimulus timing (Shigeno, 1986;McAuley, 2009, 2013).…”

Oscillatory Phase Dynamics in Neural Entrainment Underpin Illusory Percepts of Time

Neural oscillatory dynamics are a candidate mechanism to steer perception of time and temporal rate change. While oscillator models of time perception are strongly supported by behavioral evidence, a direct link to neural oscillations and oscillatory entrainment has not yet been provided. In addition, it has thus far remained unaddressed how context-induced illusory percepts of time are coded for in oscillator models of time perception. To investigate these questions, we used magnetoencephalography and examined the neural oscillatory dynamics that underpin pitch-induced illusory percepts of temporal rate change. Human participants listened to frequency-modulated sounds that varied over time in both modulation rate and pitch, and judged the direction of rate change (decrease vs increase). Our results demonstrate distinct neural mechanisms of rate perception: Modulation rate changes directly affected listeners' rate percept as well as the exact frequency of the neural oscillation. However, pitch-induced illusory rate changes were unrelated to the exact frequency of the neural responses. The rate change illusion was instead linked to changes in neural phase patterns, which allowed for single-trial decoding of percepts. That is, illusory underestimations or overestimations of perceived rate change were tightly coupled to increased intertrial phase coherence and changes in cerebro-acoustic phase lag. The results provide insight on how illusory percepts of time are coded for by neural oscillatory dynamics.
