How We Make Sense of Time

Past and future

Past and future
  • When English speakers use hand gestures to talk about the past and the future, they thrust a hand over the shoulder for the past and put a hand forward to indicate the future. English speakers also talk of the past as "leaving behind" and the future as "looking forward."
  • The Yupno people of Papua New Guinea don't think of the future as before you, but as uphill. Their concept of time is not anchored in the body, but to the world and its contours.

How humans sense time

Humans are different from animals in that we don't sense time only as passing. We dice time into units or think of time to go beyond our lifespan, such as millennia. We rely on time concepts that allow us to make plans, follow recipes, and discuss possible futures.

Describing yesterday and tomorrow

Recent research suggests that across all cultures, the concept of time depends on metaphor, known as a conceptual metaphor. We build our understanding of duration and sequences of events out of familiar spatial ideas such as size, movement, and location.

But the "time is like space" metaphor takes on very different forms from one culture to the next.

The spatial metaphors

Time is difficult to explain, yet we deal with it every day. All people talk of time as "motion on a space," and think of time as linear.

  • Durations are talked about using size ("a short weekend").
  • The passage of time is treated as a movement. ("the week flew by").
  • We think of events as located at different positions on a path - internally as "the week ahead of us" and externally as "a reception follows the ceremony."

Spacial concepts

People of all cultures lean on spatial concepts for understanding time, but exactly which spatial metaphors they use can vary.

  • The English may speak of "a long time ago," while the Aymara from the Andes refers to "a lot of time in front."
  • The Pormpuraaw, and Aboriginal Australian community, refer to the past as "to the west" and future as "to the east," while we refer to the past as "behind" and the future as "in front."

Thinking of time as space

The parts of the brain used for thinking about space are also used for thinking about time.

  • Studies reveal that people with damage to space-related brain areas also have trouble thinking about time.
  • In English and many European languages, we often think of past events to the left and future events to the right. One study found that people with disrupted spatial abilities of their left side had trouble remembering past events and even confused past events for future ones.

The influence of writing

Time as space metaphor shows up in our language and gestures, but also in depictions of external sequences of events.

  • Histories are laid out on timelines.
  • The human evolution is shown creature by creature, proceeding rightward.
  • The calendar shows the days arranged from left to right and the weeks from top to bottom.
  • Latin script proceed from left to right.
  • If you lay out three ordered images, - a banana in its peel, the banana partially peeled and the banana half eaten - English speakers will lay them out from left to right.but Hebrew speakers will lay them out from right to left.
  • Mandarin Chinese speakers refer to "last week" as above and "next week" as below. since Mandarin is written vertically, from top to bottom.

Metaphors are cultural

The concept of time reveals the human's capacity for abstract thought. But time is not the only abstract domain, nor the only one we understand through metaphor. Spatial metaphors are very common, structuring how we think about kinship, politics, and power. ("She has the upper hand.")

The particular metaphors we use, however, rely on our culture, not biological evolution.

The Challenges of The Future

As the human life span increases to span centuries, the planetary environment, along with the collaboration and cooperation among nations would come to the forefront, as hostile people and chronic pollution are extremely dangerous in the long run.

While our survival would still not be a guarantee, there will be a new challenge of overpopulation, which could be moderated by sending people into space to colonize other places, and by limiting the birth rate.

The Long Journey

As inter-galaxy travel becomes a reality, there could be many spaceships which would be able to take us to nearby habitable solar systems, setting up for new adventures, challenges and a completely radical lifestyle.

The changes in Earth’s biosphere could also be a concern, as new technologies and constant harvesting of resources (like deforestation) can lead to dangerous environmental changes.

Choice influences our decision-making

A study found that choice had an apparent influence on decision-making. In the studies subjects learned more when they had a free choice and when the choice gave a higher reward.

However, when participants were forced to select a specific choice, they were less invested in the outcomes, similar to a child mindlessly practicing to please a parent.

Choice-confirmation bias

When people can make a free choice, they embrace positive or negative outcomes that confirm they were right.

Studies show that this tendency persists in both poor and rich conditions. This means the brain is primed to learn with a bias linked to our freely chosen actions. The brain learns differently and more quickly from free choices than forced ones.

Searching For Physical Footprints

What is it about brain matter that gives rise to consciousness? In particular, the neuronal correlates of consciousness (NCC) - the minimal neuronal mechanisms jointly sufficient for any conscious experience.

Consider this question: What must happen in your brain for you to experience a toothache?

Neuronal Correlates of Consciousness (NCC)

The whole brain can be considered an NCC because it generates experience continually.

  • When parts of the cerebellum, the "little brain" underneath the back of the brain, are lost to a stroke or otherwise, patients may lose the ability to play the piano, for example.  But they never lose any aspect of their consciousness. This is because the cerebellum is almost wholly a feed-forward circuit. There are no complex feedback loops.
  • The spinal cord and the cerebellum are not enough to create consciousness. Available evidence suggests neocortical tissue in generating feelings.
  • The next stages of processing are the broad set of cortical regions, collectively known as the posterior hot zone, that gives rise to conscious perception. In clinical sources of causal evidence, stimulating the posterior hot zone can trigger a diversity of distinct sensations and feelings.
  • It appears that almost all conscious experiences have their origin in the posterior cortex. But it does not explain the crucial difference between the posterior regions and much of the prefrontal cortex, which does not directly contribute to subjective content.
