This paper reviews a large body of research which has investigated the capacities of the cerebral hemispheres to process temporal information. This research includes clinical, non-clinical, and electrophysiological experimentation. On the whole, the research supports the notion of a left hemisphere advantage for temporal resolution. The existence of such an asymmetry demonstrates that cerebral lateralisation is not limited to the higher-order functions such as language. The capacity for the resolution of fine temporal events appears to play an important role in other left hemisphere functions which require a rapid sequential processor. The functions that are facilitated by such a processor include verbal, textual, and fine movement skills. The co-development of these functions with an efficient temporal processor can be accounted for with reference to a number of evolutionary scenarios. Physiological evidence favours a temporal processing m echanism located within the left temporal cortex. The function of this mechanism may be described in terms of intermittency or travelling moment models of temporal processing. The travelling moment model provides the most plausible account of the asymmetry. IN T R O D U C T IO NTh e inherent bipartite nature of the cerebral hem ispheres has prom pted many researchers to portray hem ispheric psychological functions in terms of a dichotom ous or bipolar variable. One of the simplest and most intuitive dichotom ies describes the functions of the left and right hem ispheres in terms of their predispo sitions for the processing of verbal and non-ve rbal m aterial, respectively. Dax first noted an association between the left hem isphere (LH) and language function in the early half of the nineteenth century.

“…In fact, there is very little behavioural research investigating cerebral lateralisation in such a task. For instance, there is some evidence for a right hemisphere advantage when sequences of visual signals are used (Ben-Dov & Carmon, 1984;Grondin & Girard, 2005). Moreover, some neuroimaging studies indicate that the right hemisphere is involved in the processing of brief temporal intervals (Smith, Taylor, Lidzba, & Rubia, 2003; for a review, see Penney & Vaitilingam, 2008).…”

This experiment was conducted to determine whether perceptual asymmetries would emerge in a task requiring the discrimination of two auditory time intervals. The first interval (standard) was presented binaurally and the other one (comparison) monaurally. The intervals were either filled (continuous sound) or empty (duration between two brief sounds). A total of 24 right-handed participants (12 women, 12 men) completed the four conditions (two Ear×two Structure). The results revealed that filled intervals were perceived as shorter when the monaural signal was presented to the left ear than when it was presented to the right ear, whereas there was no ear effect for empty intervals. Interval structure was not a significant factor when the monaural signals were delivered to the right ear, suggesting a right ear advantage in duration estimation. Finally, temporal sensitivity was better with empty than with filled intervals, but this effect was independent of the location of the monaural signals. The results are discussed with reference to potential effects of attention and the role of structural aspects underlying perceptual asymmetries.

“…on the impact of using sequences of flashes. Ben-Dov and Carmon (68) used a task where two separate sequences of intervals marked by brief flashes had to be categorized as being the same or different. A short (S=.2 s) and a long (L=.4 s) interval were presented.…”

“…The main dependent variable used was reaction time. Ben-Dov and Carmon (68) showed that reaction time was faster for signals presented in the right visual field (left-hemisphere -LH-superiority) when the sequence contained fewer elements, but faster for signals presented in the left visual field (right-hemisphere -RH -superiority) when the sequence contained more elements, i.e. when a rhythm was induced.…”
