Studies have found that simply talking on the phone while walking actually slows down and disrupts our gait

When our brain is processing complex emotions and stressors, it hinders our ability to function at our best.

As I tell my students, remember to play your whole movie — not just the clip of your latest stumble on repeat

If a phone call is enough to disrupt our performance of basic tasks, we should be especially mindful of cognitive loads associated with grief, loss and general uncertainty about what is to come. All are major triggers for depression and anxiety, and profoundly affect our ability to perform even the most routine, practiced tasks.

holding tightly on to our latest failures is a common phenomenon, thanks to the recency effect — a cognitive bias that prioritizes our most recent experiences over past ones. This natural tendency sends our brain the wrong messages, and makes us forget how skilled, credentialed or qualified we really are

Adult depression and anxiety has climbed by 5.1 percent since the start of the pandemic.

Those things won’t matter nearly as much as their willingness to try again.

There's very little scientific evidence to suggest our perception of time changes as we age. And yet, we consistently report that the past felt longer — that time is flying by faster as we age. What's going on?

Scientists can look at time estimation, or our ability to estimate how long a minute passes, compared with a clock. (This is what Sothern is doing.) They can also look at time awareness, or the broad feeling that time is moving quickly or slowly. Finally there's time perspective, the sense of a past, present, and future as constructed by our memories.

What researchers have found out is that while time estimation and time awareness don't change much as we age, time perspective does. In other words: Our memories create the illusion time is accelerating.

There weren't many differences between the old and the young. "[C]hronological age showed no systematic influence on the perception of these brief intervals of time up," the authors wrote. (That said, the researchers did find that males overestimate time while females underestimate it, perhaps due to having slightly different circadian clocks and therefore slightly different metabolic rates

Here, too, age seemed not to matter. Older people didn't seem to be aware of time passing any faster than younger people. The only question that yielded a statistically significant difference was, "How fast did the last decade pass?" Even there, the reported differences were tiny, and the effect appeared to plateau around age 50.

psychologists William Friedman and Steve Janssen found scant evidence that the subjective experience of time speeds up with age. They write in their 2009 paper, "We can concluded that when adults report on their general impressions of the speed of time, age differences are very small."

When people reflect back on their own life, they feel like their early years went by very slowly and their later years go by more quickly. This could be the source of the belief that time goes more quickly as they age.

One possibility is that participants were simply biased by the (incorrect) conventional wisdom — they reported their later years as flying by more quickly because that's what everyday lore says should happen.

 "Most people feel that time is currently passing faster for them than it did in the past," Janssen writes me in an email. "They have forgotten how they experienced the passage of time when they were younger."

We use significant events as signposts to gauge the passage of time. The fewer events, the faster time seems to go by.

Childhood is full of big, memorable moments like learning to ride a bike or making first friends. By contrast, adult life becomes ordinary and mechanized, and ambles along by.

Each passing year converts some of this experience into automatic routine which we hardly notice at all, the days and weeks smooth themselves out in recollection, and the years grow hollow and collapse.

Each new minute represents a smaller fraction of our lives. One day as a 10 year old represents about .027 percent of the kid's life. A day for a 60 year old? .0045 percent. The kid's life is just... bigger.

Also, our ability to recall events declines with age. If we can't remember a time, it didn't happen.

"[F]inding that there is insufficient time to get things done may be reinterpreted as the feeling that time is passing quickly," they write. Deadlines always come sooner than we'd like.

Psychologists have long understood the phenomenon called "forward telescoping" — i.e., our tendency to underestimate how long ago very memorable events occurred. "Because we know that memories fade over time, we use the clarity of a memory as a guide to its recency," science writer Claudia Hammond writes in her book Time Warped. "So if a memory seems unclear we assumed it happened longer ago." But very clear memories are assumed to be more recent.

If our memories can trick us into thinking time is moving quickly, then maybe there are ways to trick our brains into thinking that time is slowing down — such as committing to breaking routines and learning new things. You're more likely to remember learning how to skydive than watching another hour of mindless television.

Cognitive errors result from incomplete information or the inability to analyze the information that is available. These cognitive errors can be classified as either belief perseverance or processing errors

Processing errors occur when an individual fails to manage and organize information properly, which can be due in part to the mental effort required to compute and analyze data.

Conservatism bias, where people emphasize original, pre-existing information over new data.

Base rate neglect is the opposite effect, whereby people put too little emphasis on the original information. 

Confirmation bias, where people seek information that affirms existing beliefs while discounting or discarding information that might contradict them.

Anchoring and Adjustment happens when somebody fixates on a target number, such as the result of a calculation or valuation.

Hindsight bias occurs when people perceive actual outcomes as reasonable and expected, but only after the fact.

Sample size neglect is an error made when people infer too much from a too-small sample size.

Mental accounting is when people earmark certain funds for certain goals and keep them separate. When this happens, the risk and reward of projects undertaken to achieve these goals are not considered as an overall portfolio and the effect of one on another is ignored.

Availability bias, or recency bias skews perceived future probabilities based on memorable past events

Framing bias is when a person will process the same information differently depending on how it is presented and received.

Cognitive errors in the way people process and analyze information can lead them to make irrational decisions which can negatively impact business or investing decisions

. These information processing errors could have arisen to help primitive humans survive in a time before money or finance came into existence.
