“…Perhaps of greater interest is that this bias has also been demonstrated for symbolic magnitude. For example, the perceived durations of relatively small numbers (e.g., 1, 2) tend to be underestimated, while large numbers (e.g., 8, 9) are overestimated (Chang, Tzeng, Hung, & Wu, 2011;Kiesel & Vierck, 2009;Oliveri et al, 2008;Vicario, 2011;Vicario et al, 2008;Xuan, Chen, He, & Zhang, 2009;Xuan, Zhang, He & Chen, 2007). This finding implies that time-magnitude biases are not purely sensory in nature, but emerge at a semantic level of analysis.…”

Numerical Context and Time Perception: Contrast Effects and the Perceived Duration of Numbers

In the current study, we examined how the contextual repetition of magnitude information presented in either symbolic (Arabic digits) or nonsymbolic (numerosities) formats impacted on the perceived duration of a later occurring target number. The results of the current study demonstrated a time-magnitude bias in which, on average, large magnitude target numbers were judged to last for longer durations relative to small magnitude target numbers, regardless of notation (symbolic number and numerosity). Furthermore, context effects were found, in which a greater discrepancy in the target's magnitude from the initial context led to longer perceived duration ratings. However, this was found to be asymmetrical, occurring only for large magnitude targets. Additionally, the type of context effect was shown to be determined by whether the context was presented in the same notation as the target or a different notation.

“…Another line of evidence for a shared magnitude system has been provided by experimental studies examining the interaction between magnitudes. A number of studies demonstrate bidirectional influence between space and number, (see Bueti and Walsh, 2009; see also Chang et al, 2011). Similar influence has been found between number and time, but with time processing more often affected by number processing than vice versa (e.g., Cappelletti et al, 2011).…”

Heterogeneity of Developmental Dyscalculia: Cases with Different Deficit Profiles

et al. 2017

Developmental Dyscalculia (DD) has long been thought to be a monolithic learning disorder that can be attributed to a specific neurocognitive dysfunction. However, recent research has increasingly recognized the heterogeneity of DD, where DD can be differentiated into subtypes in which the underlying cognitive deficits and neural dysfunctions may differ. The aim was to further understand the heterogeneity of developmental dyscalculia (DD) from a cognitive psychological perspective. Utilizing four children (8–9 year-old) we administered a comprehensive cognitive test battery that shed light on the cognitive-behavioral profile of each child. The children were compared against norm groups of aged-matched peers. Performance was then contrasted against predominant hypotheses of DD, which would also give insight into candidate neurocognitive correlates. Despite showing similar mathematical deficits, these children showed remarkable interindividual variability regarding cognitive profile and deficits. Two cases were consistent with the approximate number system deficit account and also the general magnitude-processing deficit account. These cases showed indications of having domain-general deficits as well. One case had an access deficit in combination with a general cognitive deficit. One case suffered from general cognitive deficits only. The results showed that DD cannot be attributed to a single explanatory factor. These findings support a multiple deficits account of DD and suggest that some cases have multiple deficits, whereas other cases have a single deficit. We discuss a previously proposed distinction between primary DD and secondary DD, and suggest hypotheses of dysfunctional neurocognitive correlates responsible for the displayed deficits.

“…For example, in a temporal discrimination task, numerical magnitudes can be activated automatically—leading to a subjective time expansion for stimuli with a large number (e.g., 9) and a time compression for stimuli with a small number (e.g., 1), even though the magnitude information was task-irrelevant (Xuan et al, 2007; Oliveri et al, 2008; Vicario et al, 2008). This phenomenon, known as number-time association (NTA) (Bi et al, 2014), has also been found in time reproduction tasks (Chang et al, 2011; Cai and Wang, 2014). …”

“…By using a temporal reproduction task with a key-press response, Chang et al (2011) found a typical NTA pattern when the perceptual/concurrent digits appeared during the standard intervals, but an opposite NTA pattern when the digits appeared during the reproductions, implying a time encoding account for the NTA. Recently, the time encoding account for the NTA has been challenged by an alternative explanation, i.e., a time memory-based account for the NTA.…”

“…An earlier study (Chang et al, 2011) suggested that task-irrelevant magnitude affected temporal processing at the encoding stage.

The Impact of Perceptual/Concurrent and Mnemonic Digits on Temporal Processing: A Congruency Effect of Numerical Magnitudes

et al. 2017

Task-irrelevant stimulus numbers can automatically modulate concurrent temporal tasks——leading to the phenomenon of number-time association (NTA). Recent research provides converging evidence that the NTA occurs at the stage of temporal memory. Specifically, a reference memory containing encoded duration information can be modified by perceptual/concurrent digits, i.e., a perceptual/concurrent digit-induced NTA. Here, with five experiments, we investigated whether another working memory (WM)-related mechanism was involved in the generation of NTAs and how this memory-induced NTA was related with the perception-induced NTA. We first explored whether similar NTA effects existed for mnemonic digits which disappeared before time encoding but were actively maintained in WM, i.e., a mnemonic digit-induced NTA. Experiments 1–3 demonstrated both types of NTAs. Further, we revealed a close relationship between the two types of NTAs in two contexts. First, the mnemonic digit-induced NTA also relied on a perceptual number-time co-occurrence at time encoding. We found that the mnemonic digits influenced subsequent temporal processing when a task-irrelevant constant number ‘5’ was presented during target encoding, but not when a non-numerical symbol was presented, suggesting that temporal representations in the reference memory could be accessed and modified by both sensory and postsensory numerical magnitudes through this number-time co-occurrence. Second, the effects of perceptual and mnemonic digits on temporal reproduction could cancel each other out. A congruency effect for perceptual and mnemonic digits (relying on memorization requirement) was demonstrated in Experiments 4 and 5. Specifically, a typical NTA was observed when the magnitudes of memorized and the perceptual/concurrent digits were congruent (both were large or small numbers), but not when they were incongruent (one small and one large numbers). Taken together, our study sheds new light on the mechanism of NTA.
