“…This holds true for RT tasks (Deary 2000;Jensen 2006), motor timing (Ullén et al 2008;), and cognitive timing tasks (Rammsayer and Brandler 2002;Rammsayer and Brandler 2007). In the present study we have investigated three timed behaviors: a simple, repetitive motor timing task (ISIP), and two RT tasks (SRT and CRT).…”

“…With exception for the SRT task, we also find significant relations between performance variables and intelligence. Null or weak relations between SRT and intelligence are not uncommon, and performance in more complex choice RT tasks typically has a stronger relation to intelligence than does SRT (Jensen 1998;Rammsayer and Brandler 2007).…”

“…Performance on such tasks is positively related to intelligence (Rammsayer and Brandler 2002;Helmbold and Rammsayer 2006;Helmbold et al 2007;Rammsayer and Brandler 2007;Troche and Rammsayer 2009), and the timing tasks are also positively correlated with each other as well as with mean RT and RTSD in RT tasks (Rammsayer and Brandler 2002;Rammsayer and Brandler 2007).…”

“…Indeed, it appears plausible that this explains part of the findings. Temporal discrimination tasks involve manipulation of temporal information in working memory, and can thus be assumed to load on executive functions (Kyllonen and Christal 1990;Rammsayer and Brandler 2002;Rammsayer and Brandler 2007). There is extensive evidence that RT tasks depend on attention, which in turn is substantially correlated with intelligence (Schweizer and Moosbrugger 2004;Schweizer et al 2005).…”

Intelligence and temporal accuracy of behavior: unique and shared associations with reaction time and motor timing Experimental Brain Research, 2011, Vol. 214, Issue 2, p. 175 -183 doi 10.1007/s00221-011-2817 Access to the published version may require subscription. Published with permission from: Springer AbstractIntelligence is associated with accuracy in a wide range of timing tasks. One source of such associations is likely to be individual differences in top-down control, e.g. sustained attention, that influence performance in both temporal tasks and other cognitively controlled behaviors.In addition, we have studied relations between intelligence and a simple rhythmic motor task, isochronous serial interval production (ISIP), and found a substantial component of that relation, which is independent of fluctuations in top-down control. The main purpose of the present study was to investigate whether such bottom-up mechanisms are involved also in the relation between intelligence and reaction time (RT) tasks. We thus investigated if common variance between the ISIP and RT tasks underlies their respective associations with intelligence. 112 participants performed a simple RT task, a choice RT task and the ISIP task.Intelligence was assessed with the Raven SPM Plus. The analysed timing variables included mean and variability in the RT tasks and two variance components in the ISIP task. As predicted, RT and ISIP variables were associated with intelligence. The timing variables were positively intercorrelated and a principal component analysis revealed a substantial first principal component that was strongly related to all timing variables, and positively correlated with intelligence. Furthermore, a commonality analysis demonstrated that the relations between intelligence and the timing variables involved a commonality between the timing variables as well as unique contributions from choice RT and ISIP. We discuss possible implications of these findings, and argue that they support our main hypothesis, i.e. that relations between intelligence and RT tasks have a bottom-up component.

“…Correct responding results in a decrease of the difference between the standard and the comparison stimulus and incorrect responding results in the task becoming easier as the difference between stimuli is increased. A detailed description of this procedure is given by Rammsayer and Brandler (2007). As an indicator of discrimination performance, the difference limen (DL), which is represented by half the interquartile range of the difference threshold [(75% threshold value -25% threshold value)/2] was determined as suggested by Luce and Galanter (1963).…”

More than a century ago, Galton and Spearman suggested that there was a functional relationship between sensory discrimination ability and intelligence. Studies have since been able to confirm a close relationship between general discrimination ability (GDA) and IQ.The aim of the present study was to assess whether this strong relationship between GDA and IQ could be due to WM demands of GDA tasks. A sample of 140 children (70 9-year-olds and 70 11-year-olds) was studied. Results showed that there was a significant overlap between WM, GDA and fluid intelligence. Furthermore, results also revealed that WM could not explain the relationship between GDA and fluid intelligence as such, but that it acted as a bottleneck of information processing, limiting the influence of GDA on the prediction of fluid intelligence. Specifically, GDA's influence on the prediction of intelligence was only visible when WM capacity was above a certain level.
