“…An even more general question that emerges from this speculation is whether the mechanisms responsible for alterations in duration j udgments induced by signal properties, whatever those might be, differ from those responsible for changes in timing associated with drugs (Maricq, Roberts, & Church, 1981;Meek & Church, 1983Spetch & Treit, 1984), nutrients (Meek & Church, 1987;Roberts, 1981), environmental stress (Meek & Church, 1983), general arousal (Poppel, 1972), and rate of reinforcement (Killeen & Fetterman, 1988). Given that the nervous system codes signal intensity in terms of general neuronal activity defined by the number and frequency of action potentials (Martin, 1985), it seems reasonable to consider that all of these variables could alter the speed of a pacemaker or could have an impact on attention.…”

“…For example, Church and Broadbent (1990) have recently outlined a connectionist model approach to timing. A key component of the model is the notion of an oscillator (Gallistel, 1990;Poppel, 1972), or more accurately, a set of oscillators. In this approach, it is assumed that timing is instantiated by an array of coupled oscillators, each having a different period.…”

A duration matching-to-sample procedure was used to examine the influence of signal properties on temporal estimation and working memory. The results indicated that pigeons responded to durations of a light as if they were longer than equal durations of the absence of the same light, but delay performances did not differ between the two sample types. Similarly, pigeons responded to durations of a bright white light as if they were longer than equal durations of a dim red light, but again, delay performances did not differ between the two sample types. These results are discussed in terms of theoretical issues pertinent to timing, attention, and working memory.Both Pavlovian and instrumental conditioning are influenced by variations in stimulus properties such as modality, complexity, intensity, and salience (

“…The neural periodicities of brain oscillations echo the time scales of perceptual structuring in audition, somatosensation and vision, and they present a hierarchical structure at local and global spatio-temporal scales (Başar 1998;Llinás et al 1998;Buzsáki 2006). In particular, the gamma band (more than 30 Hz) is likely to support approximately 30 ms integrative windows (Pö ppel 1971(Pö ppel , 1997. Synchronizations of neural populations in the gamma range are largely recognized as essential features of brain function both locally, for instance as a mechanism of feature binding in perceptual processing (Singer 1998), and globally as a large-scale support for cognitive operations (Engel et al 2001).…”

How long did it take you to read this sentence? Chances are your response is a ball park estimate and its value depends on how fast you have scanned the text, how prepared you have been for this question, perhaps your mood or how much attention you have paid to these words. Time perception is here addressed in three sections. The first section summarizes theoretical difficulties in time perception research, specifically those pertaining to the representation of time and temporal processing. The second section reviews non-exhaustively temporal effects in multisensory perception. Sensory modalities interact in temporal judgement tasks, suggesting that (i) at some level of sensory analysis, the temporal properties across senses can be integrated in building a time percept and (ii) the representational format across senses is compatible for establishing such a percept. In the last section, a two-step analysis of temporal properties is sketched out. In the first step, it is proposed that temporal properties are automatically encoded at early stages of sensory analysis, thus providing the raw material for the building of a time percept; in the second step, time representations become available to perception through attentional gating of the raw temporal representations and via re-encoding into abstract representations.

“…In opposition to the analogous concept of the "psychological (subjective) present" (e.g., Fraisse, 1984), the temporal integration interval is assumed to be independent of what is perceived. The mechanism has been detected in a large number of experiments done in various fields (Poppel, 1971(Poppel, , 1978(Poppel, , 1988(Poppel, , 1989Richards, 1964;Schleidt, Eibl-Eibesfeldt, & Poppet, 1987). The results show that the integration of successive events into perceptual forms has a temporal limit, which seems to be about 2-3 sec.…”

Musically trained and untrained subjects (N = 30) were asked to synchronize their finger tapping with stimuli in auditory patterns. Each pattern comprised six successive tonal stimuli of the same duration, the first of which was accented by a different frequency. The duration of interstimulus onset intervals (ISIs) gradually increased or decreased in constant steps toward the end of the patterns. Four values of such steps were used in different trials: 20, 30, 45, and 60 msec. Various time-control mechanisms are hypothesized as being simultaneously responsible for subjects' incorrect reproduction ofthe internal temporal ratios ofthe stimulus patterns. The mechanism of assimilation (of a central tendency) led subjects to enforce a regular (isochronous) structure on the patterns. The influence of other time-control mechanisms (distinction, subjective expression of an accent, sequential transfer) was expressed mainly in differences between intertap onset intervals (ITIs) and the corresponding ISIs at the beginning of the patterns. The duration of the first two ITIs was in the majority of the trials in an inverse ratio to the ratio of the respective ISIs. The distortions resulting from the timing mechanisms concerned were more pronounced in the performance of nonmusicians than in that of musicians.The precision and accuracy of the motor reproduction of rhythmic patterns is influenced by several aspects of stimuli, such as the internal temporal structure (interstimuIus onset intervals, ISIs), the type of tone accentuation, or the duration of the patterns. A difference in performance has been found between two basic groups of stimulus patterns-regular and irregular ones (Povel, 1981). Regular patterns are based on repetition of temporal units This work was supported by Grant PO 121/13 from the Deutsche Forschungsgemeinschaft (E.P., principal investigator) and by an Alexander von Humboldt Foundation fellowship granted to J.M.
