Friedman also contrasted two theories for a sense of time: This posits a memory trace that persists over time, by which one might judge the age of a memory and therefore how long ago the event remembered occurred from the strength of the trace.

This conflicts with the fact that memories of recent events may fade more quickly than more distant memories. The inference model suggests the time of an event is inferred from information about relations between the event in question and other events whose date or time is known.

This theory alleges that the brain can run multiple biological stopwatches at one time depending on the type of task one is involved in. The location of these pulses and what these pulses actually consist of is unclear.

Specious present The specious present is the time duration wherein a state of consciousness is experienced as being in the present. Clay in E. Robert Kelly[9] [10] and was further developed by William James.

In "Scientific Thought"C. Broad further elaborated on the concept of the specious present and considered that the specious present may be considered as the temporal equivalent of a sensory datum. There is some evidence that very short millisecond durations are processed by dedicated neurons in early sensory parts of the brain [14] [15] Professor Warren Meck devised a physiological model for measuring the passage of time.

He found the representation of time to be generated by the oscillatory activity of cells in the upper cortex. His model separated explicit timing and implicit timing.

Explicit timing is used in estimating the duration of a stimulus. Implicit timing is used to gauge the amount of time separating one from an impending event that is expected to occur in the near future. These two estimations of time do not involve the same neuroanatomical areas.

For example, implicit timing often occurs to achieve a motor task, involving the cerebellumleft parietal cortexand left premotor cortex. Explicit timing often involves the supplementary motor area and the right prefrontal cortex. The brain must learn how to overcome these speed disparities if it is to create a temporally unified representation of the external world: To accomplish this, it must wait about a tenth of a second.

In the early days of television broadcasting, engineers worried about the problem of keeping audio and video signals synchronized.

Then they accidentally discovered that they had around a hundred milliseconds of slop: He goes on to say that "This brief waiting period allows the visual system to discount the various delays imposed by the early stages; however, it has the disadvantage of pushing perception into the past.

There is a distinct survival advantage to operating as close to the present as possible; an animal does not want to live too far in the past. Therefore, the tenth-of- a-second window may be the smallest delay that allows higher areas of the brain to account for the delays created in the first stages of the system while still operating near the border of the present.

This window of delay means that awareness is postdictive, incorporating data from a window of time after an event and delivering a retrospective interpretation of what happened. Tachypsychia A temporal illusion is a distortion in the perception of time.

Time perception refers to a variety of time-related tasks. Short list of types of temporal illusions: People tend to recall recent events as occurring further back in time than they actually did backward telescoping and distant events as occurring more recently than they actually did forward telescoping.

Shorter intervals tend to be overestimated while longer intervals tend to be underestimated Time intervals associated with more changes may be perceived as longer than intervals with fewer changes Perceived temporal length of a given task may shorten with greater motivation Perceived temporal length of a given task may stretch when broken up or interrupted Auditory stimuli may appear to last longer than visual stimuli [23] [24] [25] [26] Time durations may appear longer with greater stimulus intensity e.

The kappa effect can be displayed when considering a journey made in two parts that take an equal amount of time. Between these two parts, the journey that covers more distance may appear to take longer than the journey covering less distance, even though they take an equal amount of time.

Eye movements and "Chronostasis"[ edit ] The perception of space and time undergoes distortions during rapid saccadic eye movements [29] Chronostasis is a type of temporal illusion in which the first impression following the introduction of a new event or task demand to the brain appears to be extended in time.

This elicits an overestimation in the temporal duration for which that target stimulus i.EVOLUTION TRENDS The "INFORMATION AGE" & its Evolution into the "Holographic Age" Challenges & Realistic Goals For Survival & Creating A Desirable Future.
