expansion of time, part ii

“If different temporal judgments are generated by different neural mechanisms — and while they often agree, they are not required to. Like vision, time perception is underpinned by a collaboration of separate neural mechanisms that usually work in concert but can be teased apart under the right circumstances… If time as a single unified entity slows down during fear, then this slow motion should confer a higher temporal resolution.”

“Time and memory are tightly linked. In a critical situation, the amygdala kicks into high gear… and memories are laid down by a secondary memory system… that makes them ‘stick’ better. Upon replay, the higher density of data would make the events appear to last longer. This may be why time seems to speed up as you age: you develop more compressed representation of events, and the memories to be read out are correspondingly impoverished. When you are a child and everything is novel, the richness of the memory gives the impression of increased time passage — for example, when looking back at the end of a childhood summer.”

“The recalibration of subjective timing is not a party trick of the brain; it is critical to solving the problem of causality.”

“What is the use of perception, especially since it lags behind reality, is retrospectively attributed, and is generally outstripped by automatic (unconscious) systems? The most likely answer is that perceptions are representations of information that cognitive systems can work with later. Thus it is important for the brain to take sufficient time to settle on its best interpretation of what just happened rather than stick with its initial, rapid interpretation. Its carefully refined picture of what just happened is all it will have to work with later, so it had better invest the time.”
