“…When spatial task is highly demanding, participants are more influenced by irrelevant temporal information. The overall findings corroborate recent evidence for a role of visuospatial working memory in space-time interference (Starr & Brannon, 2016) and support the interpretation of space-time interference in terms of gradient of automaticity.…”

“…In particular, future studies need to (1) explore their contribution to bias effects in dual-magnitude-judgment tasks (eg., Casasanto & Boroditsky, 2008; Merritt, Casasanto, & Brannon, 2010; Starr & Brannon, 2016), (2) their contribution to binding together two or more magnitude measurements in memory (eg., Srinivasan & Carey, 2010), and (3) whether ratios are calculated in a centralized module.…”

The existence of a generalized magnitude system in the human mind and brain has been studied extensively but remains elusive because it has not been clearly defined. Here we show that one possibility is the representation of relative magnitudes via ratio calculations: ratios are a naturally dimensionless or abstract quantity that could qualify as a common currency for magnitudes measured on vastly different psychophysical scales and in different sensory modalities like size, number, duration, and loudness. In a series of demonstrations based on comparisons of item sequences, we demonstrate that subjects spontaneously use knowledge of inter-item ratios within and across sensory modalities and across magnitude domains to rate sequences as more or less similar on a sliding scale. Moreover, they rate ratio-preserved sequences as more similar to each other than sequences in which only ordinal relations are preserved, indicating that subjects are aware of differences in levels of relative-magnitude information preservation. The ubiquity of this ability across many different magnitude pairs, even those sharing no sensory information, suggests a highly general code that could qualify as a candidate for a generalized magnitude representation.

“…For instance, while mutual interference has been observed between size and numerical magnitude (Henik & Tzelgov, 1982;Kaufmann et al, 2005;Szucs & Soltesz, 2007) and between length and numerosity (Dormal & Pesenti, 2013), previous research has shown that duration is influenced by, but does not influence, concurrent non-temporal magnitudes such as numerosity (Dormal & Pesenti, 2013;Dormal, Seron, & Pesenti, 2006), number (Droit-Volet, Clément, & Fayol, 2003 and length (Casansato & Boroditsky, 2008;Casasanto, Fotakopoulou, & Boroditsky, 2010;Magnani et al, 2014;Starr & Brannon, 2016). While in some cases duration is observed to also influence the estimation of a concurrent dimension such as length, the effect of duration on length is shown to be much smaller than the effect of length on time (Merritt et al, 2010; but see Cai & Connell, 2015, discussed below).…”

Cross-dimensional magnitude interaction is modulated by representational noise: Evidence from space-time interaction

Magnitudes along different dimensions (e.g., space and time) tend to interact with each other in perception, with some magnitude dimensions more susceptible to cross-dimensional interference than others. What causes such asymmetries in cross-dimensional magnitude interaction is being debated. The current study investigated whether the representational noise of magnitudes modulates the (a)symmetry in space-time interaction. In three experiments using different formats of length, we showed that dynamic unfilled lengths result in a higher representational noise than either static unfilled length or static filled length. Correspondingly, we observed that the time-on-space effect was larger for dynamic unfilled lengths than for static unfilled length or static filled length (and it did not differ between the latter two). Further correlational analyses showed that the susceptibility of a target dimension to the influence of a concurrent dimension increased as a function of participants’ representational noise in the target dimension (e.g., noisier length representations, a larger effect of stimulus duration on length reproduction). In all, our study showed that the representational noise of space and time modulate the way the two dimensions interact. These findings suggest that cross-dimensional magnitude interactions arise as a result of memory interference, with noisier magnitudes being more prone to being nudged by concurrent magnitudes in other dimensions. Such memory interference can be seen as a result of Bayesian inference with correlated priors between magnitude dimensions.
