“…The present work adds to the few studies that have shown that WMC, gF , and timing are strongly associated abilities in the population of healthy younger adults [18], [46]. But the separable contributions of WMC and gF to timing remain unclear.…”

“…Troche and Rammsayer [46] proposed that temporal resolution power is fundamental to both WMC and gF . According to this view, faster rates of neural oscillation (reflected in finer temporal discrimination) lead to better performance on WMC and gF tests because critical information is less likely to be lost or degraded during elementary cognitive processes supporting e.g., serial order recall or abstract problem solving (see also, e.g., [5], [63]).…”

Individual Differences in Working Memory Capacity and Temporal Discrimination

Temporal judgment in the milliseconds-to-seconds range depends on consistent attention to time and robust working memory representation. Individual differences in working memory capacity (WMC) predict a wide range of higher-order and lower-order cognitive abilities. In the present work we examined whether WMC would predict temporal discrimination. High-WMC individuals were more sensitive than low-WMC at discriminating the longer of two temporal intervals across a range of temporal differences. WMC-related individual differences in temporal discrimination were not eliminated by including a measure of fluid intelligence as a covariate. Results are discussed in terms of attention, working memory and other psychological constructs.

“…Rammsayer and colleagues, who obtained similar results in human adults, hypothesized “a temporal resolution power” and suggested that the capacity for temporal accuracy would be a major predictor of general intelligence (factor g) [45], [58], [59]. As these authors argued, the degree of temporal resolution would be an indicator of the dynamic physiological activity of our brains: A higher rate of neuronal oscillation should bring about faster and more efficient information processing and a higher level of temporal resolution.…”

The aim of this study was to examine whether age-related changes in the speed of information processing are the best predictors of the increase in sensitivity to time throughout childhood. Children aged 5 and 8 years old, as well adults, were given two temporal bisection tasks, one with short (0.5/1-s) and the other with longer (4/8-s) anchor durations. In addition, the participants' scores on different neuropsychological tests assessing both information processing speed and other dimensions of cognitive control (short-term memory, working memory, selective attention) were calculated. The results showed that the best predictor of individual variances in sensitivity to time was information processing speed, although working memory also accounted for some of the individual differences in time sensitivity, albeit to a lesser extent. In sum, the faster the information processing speed of the participants, the higher their sensitivity to time was. These results are discussed in the light of the idea that the development of temporal capacities has its roots in the maturation of the dynamic functioning of the brain.

“…Another possible moderating variable that could account for the difference between the two groups is that the musicians were more motivated when performing the timing tasks (cf., McAuley, Henry, & Tuft, 2011). Also, given that various cognitive measures predict timing ability (e.g., Helmbold et al, 2007;Rammsayer & Brandler, 2007;Troche & Rammsayer, 2009), an additional alternative explanation could be that there is a selection bias in a sense that individuals with higher cognitive ability go on to study music. In the present study, however, all musicians and nonmusicians were graduate students and the two groups did not differ in mean ZVT score, a global measure of general intelligence.…”

Musicians Do Better than Nonmusicians in Both Auditory and Visual Timing Tasks

the present study was designed to investigate differences in auditory and visual temporal information processing between musicians and nonmusicians. For this purpose, timing performance on a set of six different psychophysical temporal tasks for both the auditory and visual sensory modalities was compared in 40 formally trained musicians and 40 controls without musical experience. Across modalities, superior temporal acuity for musicians compared to nonmusicians could be shown for all temporal tasks except for temporal generalization. When comparing the two sensory modalities, temporal acuity was superior to auditory stimuli as compared to visual stimuli, with the exception of the temporal generalization task in the 1-s range. The overall pattern of our findings is consistent with the notion that musicians' long-lasting intensive music training, starting in childhood, improves general timing ability irrespective of sensory modality.
