How Words Are More Than Words

‘Sticks and stones may break my bones but words will never hurt me.’

Popular as they are, those words really aren’t as accurate as we would like them to be.

Words are a part of almost every aspect of our lives, and the words we use impact not only those we are speaking to, but the very way we see the world – and even the chemicals released in our brain.

The Psychology of Rivalries

Even though competing sports teams who consider themselves rivals like to highlight their supposedly apparent differences – in actuality, rivals are more alike than they are different. They share a common goal, for which they are competing.

Rivalries allow us as humans to have a friendly competition. They can be energizing, and allow us to bond with our communities over success or failure.

What is Texting and Email Doing to Face-to-Face Communication?

How does immediate mobile contact affect our relationships in real life?

If you live in the modern world – as you most likely do – you’re probably seen it: two people standing next to each other, engrossed in text conversations happening on their mobile devices, while oblivious to each other or anything else happening around them. 

Does that common occurrence make you reminisce about the good old days of landlines? You’re not alone. Many people pine for simplicity in this new world of immediate contact – all possible through our nifty mobile gadgets.

When Our Brains Go on Autopilot

Mindless eating in front of the TV is one example of automaticity.

We may think we’re making conscious decisions about everything we do on a daily basis – but a large portion of things we do during each day, we do without thinking about them.

Take turning on a light, or consuming snacks in front of the TV. These automatic behaviors are great because they allow our brains to consider more complex ideas and thoughts. They’re great, that is, until we are doing things automatically that are harmful to others or ourselves.

How to Learn From Failure

Success and failure: What's the difference? What's the value?
Credit stockmonkey.com

Failure is a scary word that carries a very negative connotation: “I’m a failure.” “He’s a failure.” “I don’t want to be a failure.” 

The word failure arouses emotional responses that we’d usually rather avoid.  What about the word success  The thought of success arouses images of comfort, ease and satisfaction.  Why?  It’s because of something in our brains. 

We’re wired with a dopamine reward system that releases positive or negative chemical affect in our brains depending upon the success or failure of our efforts.  Success feels good, while failure feels bad.  So we tend to seek success and avoid failure. It’s simple.  

But hang on a minute and let the Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke, tell you about a function of failure that is too often overlooked and discredited: Failure is a learning tool.

Who Controls Your Destiny?

Should I stay or should I go? Recognizing our ability to get up and leave stressful situations represents an internal locus of control – a belief in our inherit ability to control situations.

So how do we define Locus of Control?  Essentially, it’s our positioning of ourselves within our perception of the world and the way that we perceive our power and influence. We can either feel in control of our lives – which is reassuring – or we can feel subjected to forces outside of our control – which we are then forced to endure. When that happens, we can feel stuck. 

Feeling stuck, with no other options, often leads to prolonged periods of stress. That in turn can depress our health – physically, mentally and emotionally. But since we construct our perceptions of reality, we have the option to shift our locus of power. That way we can then redefine the source of power in any circumstance – taking it when needed, or giving it up when needed. (In some stressful circumstances, having less control over the outcome of a situation can actually be preferred.)

This is Your Brain on Music

Learning an instrument, especially as adults, provides us with a type of "brain food" that can help to protect our brains against damage. Experiencing music together is also an important part of being human.

We like to be in sync. Experiencing live music with others, whether you're playing an instrument or not, provides a certain synchronized relationship that boosts our feelings of togetherness and enjoyment.

How Advertising Works On Your Brain

Don Draper from Mad Men may have been unaware of the neuropsychological reasons that he intuitively constructed advertisements the way he did, or he may not have cared, but there are reasons.

Have you ever found yourself in a shopping isle at the grocery store, mindlessly putting products into your cart? Why do you prefer one brand over another?  Why does one item seem to just call out your name? Effective advertising might be the reason.

What's Happening Inside Your Head When You Sleep

We need to sleep for a host of reasons, but what exactly is happening in our brains while we’re unconscious? We've only scratched the surface of understanding all that happens during sleep, but we do know that while our bodies are resting, our brains are very busy.
