“…This hypothesis is particularly appealing considering, as noted by Efron (1990), that time sense and language are associated, because (1) language requires a temporal ordering of sequences of sounds, and (2) its cerebral location is known to be also the LH. Considerable evidence shows the role of the LH in the judgments on temporal order, gap detection, and simultaneity or successiveness (Efron, 1963;Mills & Rollman, 1980;Nicholls, 1994), and there are reports consistent with an LH-timer hypothesis for the estimation of brief intervals (Mills & Rollman, 1979;Polzella, DaPolito, & Hinsman, 1977) and interval production (Sergent, Hellige, & Cherry, 1993).…”

The capability of subjects to categorize (as short or long) visually marked empty time intervals was investigated in three experiments. Two visual signals, located 18°to the left (L) and to the right (R) of a fixation point in the visual field, established four marking conditions, two unilaterally presented (L-L and R-R) and two bilaterally presented (L-R and R-L). In Experiments 1 and 2, the results show that discrimination is better with unilateral sequences than with bilateral sequences and that the perceived duration is longer with an L-R than with an R-L sequence. In addition, Experiment 2 shows that, in comparison with a condition in which Markers I and 2 remain identical for a complete session, varying the markers from trial to trial does not decrease discrimination. Also, Experiment 2 shows that discrimination is better when both visual markers are presented at fovea than it is in the unilateral conditions. Experiment 3 shows that bilateral intervals are perceived as being longer and are better discriminated than are intervals marked by an intermodal sequence (auditory-visual or visual-auditory). The general discussion reports the implications of having different perceived duration and sensitivity levels, in various marker-type conditions, for an internal-clock hypothesis. Some implications of these results for a lateralized-timer hypothesis are also discussed.

“…Were the laterality differences reported by Erwin and Nebes (Note 1) and by Polzella et al (1977) primarily based on visible persistence, on schematic persistence, or on both? Neither study can provide a pertinent answer because neither experimental task was selectively sensitive to one or the other form of persistence.…”

“…Polzella, Da Polito, and Hinsman (1977) displayed random aggregates of dots to the left visual field (LVF) or to the right visual field (RVF) of subjects who were required to estimate the apparent duration of the display. Numerosity of dots in each display was varied between one and five; duration of each display was varied between 16 and 100 msec.…”

Nine right-handed subjects performed a visual task requiring perceptual integration of a pattern whose parts were displayed sequentially in time. Correct performance on the task depended critically on the simultaneous visibility of all parts of the pattern; duration of visible persistence could therefore be gauged by varying the duration of the temporal interval between successive portions of the display. The pattern was displayed either foveally or parafoveally in either visual field. Analysis of overall performance and of distribution of errors at each temporal interval revealed more accurate performance for foveal displays but no hemispheric asymmetries in duration of visible persistence. These and other results reported in the literature are interpreted in terms of Moscovitch's (1979) information-processing model of hemispheric functioning.

“…This hemisphere was also more accurate in predicting events in time. On the basis of complex research , Polzella et al (1977) came to the conclusion that following Thomas and Weaver's model, the left hemisphere "relies on a timer to estimate duration while the right hemisphere relies on a visual informa tion proc essor to estimate duration," p. 1187. These results need to be con fIrmed.…”
