Social foraging strategies illustrate the balance between competition and cooperation, where individuals either produce resources or exploit the efforts of others, navigating ecological and social constraints.

Many situations contain irreducible uncertainty. No matter how many variables we try to control, we can't reduce uncertainty to zero. It's inherent in the messiness of life.

For my sons, those experiences proved incredibly valuable. Both of them learned to value their athletic experiences not so much for the awards they won or accolades they received but for what participating in those events did for them on the inside. In comparing their childhood experiences to my long-distance running, I realized that many of my own fondest running memories did not come from the buckles or plaques I received but rather from the internal gratification I enjoyed in completing something really difficult.

Dopamine is one of the most extensively studied neurotransmitters, chemicals that convey signals from cell to cell. It's the one with the highest profile outside neuroscience: often known as the 'pleasure chemical', it's depicted as the hit of reward that people get from recreational drugs or scrolling through social media. That's a gross simplification of what dopamine does; on that, researchers agree.

They created an artificial 'mental map', with pleasantness along one axis and bodily reactions along the other, and charted how the brain responded while watching clips from films. The results revealed clear groupings in the way that our brains represent emotion - with guilt, anger and disgust in one corner and happiness, satisfaction and pride in the other.

According to the Free Energy Principle (FEP), developed by theoretical neuroscientist Karl Friston and colleagues, much of what the brain does can be understood as minimizing such mismatches—a technical form of 'surprise' defined as the improbability of sensory input given an internal model. The proposal brings perception, action, learning, and decision-making under a single framework.

For my colleagues and me, whose task it is to improve population health, we architect specific health interventions because doing so gives us a measurement advantage. Through good intervention design, we (or the intervention's facilitators) can track attendance, program completion, vital signs, functional capacity, clinical labs, and downstream health utilization. Yet, despite our best design efforts, we still chronically face a fundamental challenge: program adherence.

The human brain is engineered to ignore most of what it sees and hears, according to the neuroscientists I interviewed for the audio original Viral Voices. If that's the case, how are you supposed to make a memorable impression? The empowering news is that if you understand how the brain works, what it discards, and what it pays attention to, you'll be far more persuasive than you've ever imagined. Persuasive people have influence in their personal and professional lives.

First, you have to facilitate through the situation, which means realigning your mindset and asking yourself what you need to do to effect change for the next time you see this behaviour. Once this mindset has been established, there is a sequence of steps we must avoid to be able to effect change. These are as follows: 1. Do not allow your reactions to be based on what your child is saying.

Adult content has never been as accessible as it is now, thanks to the internet. Hell, online smut played a major role in the rise of the web itself in the 1990s. With that glut of porn, some have voiced concerns that some people are consuming too much of the stuff or even becoming addicted, which they claim could have consequences like regulating emotions or impaired sexual functioning.

At the Winter Olympics, skiers, bobsledders, speedskaters, and many other athletes all have to master one critical moment: when to start. That split second is paramount during competition because when everyone is strong and skilled, a moment of hesitation can separate gold from silver. A competitor who hesitates too much will be left behind -but moving too early will get them disqualified.

Neuroscientists have a name for the brain network that fires up when you're not focused on an external task: the default mode network, or DMN. It's the constellation of regions - the medial prefrontal cortex, posterior cingulate cortex, and angular gyrus among them - that hums to life when you daydream, reflect on yourself, or think about other people's mental states.

There are lots of reasons why relationships fall apart; all kinds of incompatibilities can doom romance. Some are trivial, but occasionally there might be something more profound at the root of an estrangement. Recently, the concept of the "frontal lobe breakup" appeared in popular culture. The idea is that the final stage of development in the executive regions of the brain-the frontal lobes-changes someone's perspective about their relationship. The onset of advanced cognitive skills in one partner creates a gap in maturity too big to bridge.

Ability is thought of as being an internal stable factor over which a person may not think they have any control. However, one should consider that the ability to control one's own learning may become available to an individual if they actively engage in their learning. This active learning engagement has the potential to change neurological pathways, leading to changes in cognitive and skill-acquisition capacities, as well as advances in knowledge, potential, insight, and creativity(Arrowsmith-Young, 2012; Coyle, 2009; Doidge, 2010, 2015).

'Have you ever noticed how your day starts?' Khan asks in a YouTube video on his channel, The Brain Project. 'You open your eyes, and your hands already know what to do. Same apps, same path to the kitchen, same routines you never actually chose. 'It feels automatic because, well, it is. Habits aren't a personality trait, they're neural shortcuts your brain builds to save energy.'

Praise. Universally good, right? Those of you who are fans of Alfie Kohn's (2018) work know it isn't. Praise comes with baggage. I (EB) was reminded of another downside by a young adult patient who sees praise as invalidating or dismissive of a person's experience. What about this exchange? Person: "I can't do it." Response: "Yes, you can. You are so amazing and strong."

I am a worrier, and have been for most of my life. At some point, someone dear and smart teased me that I worry about the wrong things. The things that hit me, she noted, were never the things I worried about. For a while that left me feeling like an incompetent worrier-until my research caught up. I realized that the things I worry about often don't end up hurting me precisely because worrying helps me diffuse them ahead of time.
