“…In summary, we described for the first time that arithmetic operations on temporal durations produce systematic estimation errors that primarily depend on the type of operation (and to a smaller extent by the size of the operands). Our results show that the over-reproduction found in a multisensory task (Takahashi & Watanabe, 2015) is only one side of the coin. The (opposite) effect for subtraction is crucially present and allows us to cast the overall pattern within the broader theoretical framework of representational momentum.…”

“…After a fixation dot (1000 ms) a first stimulus (white noise) was played (duration: 600 ms for addition or 1200 ms for subtraction). Then the "+" sign (perform addition) or the "-" sign (perform subtraction) appeared for a random interval (range: from 600 ms to 1000 ms) which did not allow participants to use any heuristic based on the total duration of the stimuli (Takahashi & Watanabe, 2015). After its disappearance, a second sound (150, 300 or 450 ms long) was played.…”

“…Imagined equidistant events are rated closer in time when they are about to happen than when they had already happened. Takahashi and Watanabe (2015) found that summation of temporal durations led to overestimation, regardless of the sensory modality of the stimuli. Fortin and Breton (1995) and Fortin and Massé (2000) reported that, all other parameters being equal, a larger number of temporal durations to be added furthere increases the pattern of overestimation.…”

“…Consequently, individuals are able to make common relativized descriptions such as identifying the shortest and or the longest durations, or computing the average of different time intervals in various contexts to adapt behavior and guide decisions. It also enables brains to compute the sum or difference of a number of durations (Gibbon & Church, 1981; Takahashi & Watanabe, 2015; Wearden, 2002), which helps individuals to adaptively execute behaviors at the correct time and in the correct amount of time.…”

Temporal information-processing is critical for adaptive behavior and goal-directed action. It is thus crucial to understand how the temporal distance between behaviorally relevant events is encoded to guide behavior. However, research on temporal representations has yielded mixed findings as to whether organisms utilize relative versus absolute judgments of time intervals. To address this fundamental question about the timing mechanism, we tested mice in a duration discrimination procedure in which they learned to correctly categorize tones of different durations as short or long. After being trained on a pair of target intervals, the mice were transferred to conditions in which cue durations and corresponding response locations were systematically manipulated so that either the relative or absolute mapping remained constant. The findings indicate that transfer occurred most readily when relative relationships of durations and response locations were preserved. In contrast, when subjects had to re-map these relative relations, even when positive transfer initially occurred based on absolute mappings, their temporal discrimination performance was impaired, and they required extensive training to re-establish temporal control. These results demonstrate that mice can represent experienced durations both as having a certain magnitude (absolute representation) and as being shorter or longer of the two durations (an ordinal relation to other cue durations), with relational control having a more enduring influence in temporal discriminations.

Temporal information-processing is critical for adaptive behavior and goal-directed action. It is thus crucial to understand how the temporal distance between behaviorally relevant events is encoded to guide behavior. However, research on temporal representations has yielded mixed findings as to whether organisms utilize relative versus absolute judgments of time intervals. To address this fundamental question about the timing mechanism, we tested mice in a duration discrimination procedure in which they learned to correctly categorize tones of different durations as short or long. After being trained on a pair of target intervals the mice transferred to conditions in which cue durations and corresponding response locations were systematically manipulated. Specifically, responses and/or durations of cues were switched in different experimental phases so that either the relative or absolute mapping remained constant. The findings indicate that the transfer occurred most readily when relative relationships of durations and response locations were preserved. In contrast, when the animals had to re-map these relative relations, their temporal discrimination ability was impaired, and they required extensive training to re-establish temporal control. However, preserving the response location of one of the cue durations in such conditions was found to help with initial transfer. These results demonstrate that mice can represent experienced durations both as having a certain magnitude (absolute representation) and as being shorter or longer of the two durations (an ordinal relation to other cue durations), with relational control having a greater influence in temporal discriminations.
