“…This result, together with the approximately linear relation exhibited in Figure 4, supports Rule and Curtis's (1985) conclusion that the nonlinearity found when subjective durations of two simultaneous intervals are combined stems from a later stage of processing, a stage between the subject's monitoring of duration and the subject's judgment. That is, interactions found in judgments such as judgments of average duration of two simultaneous events are due not to how the two durations are perceived, but to how the perceived durations are later combined to yield a composite response.…”

“…The durations were seven intervals, which are equally spaced when raised to the 1.25 power: 0.50 sec, 2.61 sec, 4.31 sec, 5.85 sec, 7.30 sec, 8.68 sec, and 10.0 sec. These durations are the same as those used by Rule and Curtis (1985) and were employed in the present study to provide comparability of results. A yellow light on the display panel served as a ready signal.…”

“…In this case, the curves are parallel, the trend that has been found for successive presentations (e.g., Blankenship & Anderson, 1976). Rule and Curtis (1985) examined differences in trends for successive and simultaneous presentations when judgments of average durations of both presentation conditions were intermixed within the same series ofjudgments. Subjective measures of duration were obtained by subjecting the combined data to a nonmetric analysis.…”

“…When a subject judges the combined duration of two time intervals, mathematical descriptions of how the subjective durations are combined depend upon whether the time intervals are presented successively or concurrently (Curtis & Rule, 1977;Rule & Curtis, 1985;Rule, Mahon, & Curtis, 1983). For successive intervals, a linear rule describes the subjective combination of the two perceived durations.…”

When a subject is required to combine the subjective durations of two events that occur sequentially, the perceived durations are combined linearly. However, when two events occur concurrently, the perceived durations appear to combine in a nonlinear manner. The conclusion of a nonlinear composition rests on an assumption that the perceived duration of each interval occurring in a pair is equivalent to the perceived duration of the same interval presented alone. Forty subjects gave separate ratings to each member of pairs of intervals presented simultaneously. The time intervals ranged from 0.5 to 10.0 sec. Plots ofthe ratings did not exhibit converging trends previously found when subjects were required to judge the combined durations of pairs of intervals. The ratings were also close to linear with ratings ofthe intervals presented individually to an independent group of 30 subjects. The results indicate that the nonlinearity previously found when subjects evaluated combined durations enters into the relation at a later stage of processing after the subjective durations of the intervals have been monitored.where 1/;ij represents the subjective measure of the con-

“…However, we know from everyday life and from a growing body of research that humans and even non-human animals are able to estimate the durations of more than one stimulus simultaneously (cf. Curtis and Rule, 1977; Rule et al, 1983; Meck and Church, 1984; Rule and Curtis, 1985; Brown and West, 1990; van Rijn and Taatgen, 2008). …”

With two experiments it was examined whether one or two clocks operate the timing of two intervals presented simultaneously. The target interval always preceded the distracter interval, and was longer than it. Thus, the distracter was completely embedded within the target interval. The participants used the method of temporal production. The stimuli to be judged differed in modality which allowed for testing the hypothesis of modality-specific internal clocks that operate in parallel and independent from one another when two stimuli were presented at the same time. The main results of this study were as follows. First, production times of the target interval increased proportionally with production times of the distracter interval. Second, the auditory distracter interval was on average produced in less time than the visual distracter interval. Third, a target interval that was accompanied by an auditory distracter interval was on average produced in less time than a target interval that was accompanied by a visual distracter interval. The results obtained support the hypothesis of multiple clocks being involved in the timing of different intervals presented simultaneously.

"Ratio" and "difference" judgments for length, area, and volume: Are there two classes of sensory continua?

Subjects were required to judge ratios and differences of (a) line length for pairs of lines, (b) area for pairs of squares, and (c) volume for pairs of cubes. Nonmetric analyses of these judgments indicated that all subjects were able to make consistent ratio judgments for all three continua. Many of the subjects, when asked to judge subjective differences, however, performed as if they were judging subjective ratios rather than differences. The data for the few subjects who appeared to be judging subjective differences were not consistent across subjects and conditions. Previous studies of ratio and difference judgments of loudness and heaviness, on the other hand, showed the opposite pattern, in that subjects most often behaved as if they were judging sensory differences when asked to judge sensory ratios. We propose that ratio judgments are more natural to perceptual continua along which stimuli are easily "decomposed" into a number of smaller perceptual units.
