In Scientific American of 19 Jun 2011, Why Does Time Fly? by Martin P. Paulus:
Something moving toward you has more relevance than the same stimulus moving away from you: You may need to prepare somehow; time seems to move more slowly.
This would be consistent with a stochastic grammar model of the brain. A stochastic grammar weights events in as they occur to determine prior probabilities, which in turn predict next possible events (posterior probabilities). When new events fit the predictions of highest probability, little change occurs in the stochastic grammar processing. However, when the predictions of lowest probability occurs, such as looming danger, the stochastic grammar incurs marked modifications of its weights, that in turns reset new expectations.
This change of weight in the stochastic grammars corresponds in the brain to a change in the glial and neuronal activity, which involves chemical and electrical mechanisms that are not instantaneous. So, if the activity of the stochastic grammar would be the measure that the brain uses for evaluating time elapsed, that would create a measure of the effect at hand, and a means to actually experiment with the validity of the model.
