AbstractSpatial and temporal information processing interfere with each other. Kappa effect is a famous spatiotemporal interference, in which the estimated time between two lights increases as an increase of distance between the lights, showing a tendency of deceleration. A classical model attributes the interference to constant speeds and predicts a linear relation, whereas a slowness model attributes the interference to slow speeds and proposes the tendency is the result of the variance of stimuli locations. The present study developed a logarithmic version of the classical model and asserts that the tendency is the result of the Web-Fechner law. These hypotheses were tested in two time discrimination tasks by manipulating the variance of stimuli locations and distance between stimuli. The results demonstrate that estimated time was not modulated by the variance of stimuli locations, and increased as an increase of distance with a tendency of deceleration. The Bayesian model on logarithmic scales made more accurate behavioral predictions than the linear model; the estimated constant speed of the logarithmic Bayesian model was equal to the absolute threshold of speed; the strength of the Kappa effect positively correlated with the variability of time perception. Findings suggest that the interference in the Kappa effect is driven by slow speeds, the strength of the interference is influenced by the variability of time perception, and the tendency of deceleration is the result of the Weber-Fechner law. This Bayesian framework may be useful when applied in the field of time perception and other types of cross-dimensional interferences.

52 women and 20 men ( M age = 25.3 yr., SD = 4.1) reproduced one of three durations (15, 30, and 45 sec.) of a uniform visual stimulus in either a prospective or a retrospective estimation paradigm. In contrast to the prospective conditions, the participants in the retrospective conditions did not know that time estimation would be required subsequently. However, temporal relevance in the retrospective conditions was raised explicitly by instructing the participants to wait for the termination of a visual stimulus and to press a button immediately after the stimulus had disappeared. The results contrasted with most findings of comparisons between prospective and retrospective duration judgments: there were no differences between the conditions regarding their mean estimates. However, intersubject variability of temporal judgments was higher in the retrospective conditions than in the prospective conditions. The results were interpreted within the framework of attentional models of temporal information processing.

The neural basis of temporal information processing remains unclear, but it is proposed that the cerebellum plays an important role through its internal clock or feed-forward computation functions. In this study, fMRI was used to investigate the brain networks engaged in perceptual and motor aspects of subsecond temporal processing without accompanying coprocessing of spatial information. Direct comparison between perceptual and motor aspects of time processing was made with a categorical-design analysis. The right lateral cerebellum (lobule VI) was active during a time discrimination task, whereas the left cerebellar lobule VI was activated during a timed movement generation task. These findings were consistent with the idea that the cerebellum contributed to subsecond time processing in both perceptual and motor aspects. The feed-forward computational theory of the cerebellum predicted increased cerebro-cerebellar interactions during time information processing. In fact, a psychophysiological interaction analysis identified the supplementary motor and dorsal premotor areas, which had a significant functional connectivity with the right cerebellar region during a time discrimination task and with the left lateral cerebellum during a timed movement generation task. The involvement of cerebro-cerebellar interactions may provide supportive evidence that temporal information processing relies on the simulation of timing information through feed-forward computation in the cerebellum.

This chapter elaborates on the concepts of music information and information processing by bringing together the fields of computation, cybernetics and the dynamic systems approach. It conceives of music users as autonomous agents that behave as adaptive devices that construct their musical knowledge as the outcome of continuous epistemic interactions with the sonic world. As such, it challenges the classical symbolic-conceptual approach to musical information in terms of static, discrete and objective categories in favor of a trans-classical model that relies on subjective, process-like and non-discrete categories of meaning. In an attempt to go beyond traditional dichotomies, it proposes a hybrid perceptual-conceptual approach that does justice both to the richness and fullness of perceptual experience and the plasticity of mental operations in a kind of symbolic play.
