Duration reproduction with sensory feedback delay: differential involvement of perception and action time.

Ganzenmüller S, Shi Z, Müller HJ - Front Integr Neurosci (2012)

Bottom Line: However, whether and how sensorimotor delay affects duration reproduction is still unclear.These findings indicate that participants tend to mix the onset of action and the feedback signal more when the feedback is delayed, and they heavily rely on motor-stop signals for the duration reproduction.Furthermore, auditory duration was overestimated compared to visual duration in crossmodal feedback conditions, and the overestimation of auditory duration (or the underestimation of visual duration) was independent of the delay manipulation.

ABSTRACT
Previous research has shown that voluntary action can attract subsequent, delayed feedback events toward the action, and adaptation to the sensorimotor delay can even reverse motor-sensory temporal order judgments. However, whether and how sensorimotor delay affects duration reproduction is still unclear. To investigate this, we injected an onset- or offset-delay to the sensory feedback signal from a duration reproduction task. We compared duration reproductions within (visual, auditory) modality and across audiovisual modalities with feedback signal onset- and offset-delay manipulations. We found that the reproduced duration was lengthened in both visual and auditory feedback signal onset-delay conditions. The lengthening effect was evident immediately, on the first trial with the onset-delay. However, when the onset of the feedback signal was prior to the action, the lengthening effect was diminished. In contrast, a shortening effect was found with feedback signal offset-delay, though the effect was weaker and manifested only in the auditory offset-delay condition. These findings indicate that participants tend to mix the onset of action and the feedback signal more when the feedback is delayed, and they heavily rely on motor-stop signals for the duration reproduction. Furthermore, auditory duration was overestimated compared to visual duration in crossmodal feedback conditions, and the overestimation of auditory duration (or the underestimation of visual duration) was independent of the delay manipulation.

Normalized reproduction errors for the onset- and offset-delay condition of Experiment 3 (A) and Experiment 4 (B). In the upper and middle panels trial-wise dynamic changes of normalized reproduction are shown. Four trials from the synchronous block before the delay manipulation (baseline phase), delay block (delay phase), and four trials after the delay manipulation (post phase) are displayed. The black lines indicate the physical delay. The red dashed curves and circles depict mean normalized reproduction errors as a function of trial sequence and the onset-delay (up-panel) or offset-delay (middle panel). In the low-panels mean normalized reproduction errors (and associated standard errors) are plotted against baseline, delay, and post phase for the onset- and offset-delay conditions. The dashed line indicates the mean normalized reproduction error in the baseline condition.

Mentions: Overall, there was strong underestimation of the visual standard with synchronous auditory feedback signal (hereafter we refer to as the visual-auditory experiment), and strong overestimation of the auditory standard with visual feedback signal (hereafter the auditory-visual experiment), all p < 0.01. Trial-wise normalized reproduction errors for the onset- and offset-delay manipulations are depicted in Figure 4.
