Abstract Children born shortly before the cutoff date for age grouping in youth sport programs suffer from being promoted to higher age groups earlier than their later-born peers. Skewed birthdate…

The present review article discusses the question of whether there is an internal clock (pacemaker counter or oscillator device) that is dedicated to temporal processing and reports the main hypotheses regarding the involvement of biological structures in time perception.

After examination of the status of time in experimental psychology and a review of related major texts, 2 opposite approaches are presented in which time is either unified or fragmented. Unified time…

The results indicate that when the attention is directly controlled by the subject, the subjective duration shortens as the amount of attention devoted to the temporal task diminishes.

The results of three experiments on the discrimination of time intervals presented in sequences marked by brief visual signals showed that between 900 and 1,200 msec (Experiment 3), the Weber fraction increased, well described by Weber’s law.

The results showed that the differential threshold differences among marker types are important for short durations but decrease with longer durations, and that a generalized Weber’s law generally holds for these conditions.

The results demonstrated that the variability to time ratio is not constant across the standard interval conditions, and the ratio is higher at 1.9 than at 1 s, which is a violation of scalar timing.

Overall, the results reveal that increasing the number of comparison intervals or the duration range does not seem to affect the value of the WF and that theWF is lower at 0.2 sec than at 1 sec, which is inconsistent with the scalar property of some timing models.

The present chapter focusses on Weber law, also referred to as the scalar property in the field of time perception, and the question addressed here is does variability increase linearly as a function of the magnitude of the duration under investigation.
