There are a lot of stereotypes about how men and women seek out different qualities in a mate. But researchers from the University of Texas say they now have a clearer picture of just how different the preferences of men and women are.

As part of the study, researchers asked people (all of whom identify as heterosexual) what they find desirable in a partner. Judging from their answers, researchers were able to guess with 92 percent accuracy whether the respondent was male or female.

“The patterns in the sexes barely overlap at all,” says Dan Conroy-Beam, a UT grad student and lead author of the study. Conroy-Beam says women tend to prefer a partner who is more financially established and older, while men place a premium on physical attractiveness and youth. That, he says, tells us when the sexes are going out and looking for a mate, they’re looking for something completely different.

The human brain is perhaps the most complicated machine in the known universe, and the way we sometimes try to understand it’s capacity is to liken it to the most sophisticated artifacts we’ve created. The brain is hence “like a computer” and no longer like the “steam engine” it was compared to in the late 19th century.

The circuitry in the brain is made up of pretty basic materials, so it’s understandable that we would try to replicate it.  Yet it seems the more we learn about the brain, the more complex it becomes.The development of A.I., while it brings about a better understanding of how our brains work, it also generates more questions about what it means to be human.

What counts as “human”? Why is intelligence the marker of humanity? And what types of questions are currently vexing computer scientists, psychologists, and philosophers about A.I.?

In this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke take us through a brief history of the development of artificial intelligence, and pose some interesting questions about where we might be headed.

We value brains. We hold test scores in high esteem. We spend money and hours on brain training games and ginseng. But what does intelligence really mean? How do we define and gauge actual smarts? Does a high IQ predict success?

In this episode of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke talk about the history and development of intelligence tests; as well as what these tests can actually tell us about one's ability to achieve.

Halloween will soon be upon us, and among the ghouls and goblins walking the streets, you might see someone dressed up an Ebola patient out asking for candy. How will you respond?

Would you buckle over in laughter, or would you be totally offended by this irreverent ode to this devastating threat?

In this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke discuss why we respond to fear and other uncomfortable and threatening situations with humor.

Happiness may be one of the most common and egalitarian of human emotions, but all aren't created equal when it comes to elation.

The work of Harvard’s Dan Gilbert speaks to findings in psychology that reveal that people have about a 50-10-40 ratio for happiness – 50 percent depends on genetic makeup; 10 percent depends on what happens to us throughout the day; and 40 percent is dependent on how we react to those environmental goings-on.

So, why is it some of us are more predisposed than others to see the glass as half empty as opposed to half full?

In this edition of “Two Guys on Your Head,” Dr. Art Markman and Dr. Bob Duke discuss how self-imposed strategies might give us an edge when it comes to feeling happier.

Procrastination is the all-too-familiar foe of productivity, but why do some wait until the last minute to even get a project started?

In this episode of "Two Guys on Your Head" Dr. Art Markman and Dr. Bob Duke explore the psychology behind procrastination, and how we can overcome factors that might be keeping us from getting started.

Can you remember what it was like for you to learn your native language?  Probably not, but why is that?

As humans, we begin learning to speak our native language during the earliest stages of our lives, in infancy.  Most people don’t have many accessible memories from this period of development. How do we do that?

If we can learn a language in our infant stages of life, why is it so difficult to learn a second language later in life?

On this week’s episode of Two Guys on Your Head, Art Markman and Bob Duke explore how we learn language.

We may think of our memory functioning much like a movie camera does; capturing a scene and replaying it in a linear fashion. Yet, in actuality, it’s more like catching bits of paper at a ticker tape parade and weaving together a story of the past by re-constructing the pieces of paper we and others around us catch.

In this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke explain how and why we construct memories, and how our memories can be influenced by variables that we may never consider.

Failure is a word that carries a lot of baggage, arousing emotional responses that we’d usually rather avoid. 

What about success? Why does the thought of success conjure images and feelings of comfort and satisfaction. This week, "Two Guys on Your Head" examine how the heights of success and the "training wheels" of failure impact our everyday lives.

The 24-hour-news cycle is ingrained into most adults' lives. Global conflict, natural disasters and crime make their way into in our daily discussions with a sense of normalcy. But for the young and impressionable, the news can paint a rather grim portrait of the world. So how do you go about explaining disturbing world events to your children?

The Texas Standard's David Brown speaks with licensed family and children’s counselor Khris Ford, who gives us some insight on how children perceive the events in the news.

Being the incredibly social species that we are, we humans simply cannot avoid influencing one another when we interact. Influence is inevitable. 

The question then becomes, since influence is inevitable in human interaction, can we achieve the kind of influence that we intend to have, or that we might think we have in the world? 

On this week’s show, the Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke, influence our understanding of the different functions and effects of influence in our lives.

What’s so funny?

In this week’s show, the Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke, analyze laughter until it cracks you up.

Why is it that laughter is such a seemingly uncontrollable response? There's many angles in a discussion on laughter, since there is no definitive way of explaining or understanding such a complex aspect of life. So lets start by noting laughter is a form of social bonding.

Swiss psychiatrist Jean Piaget was born in 1896, and died in 1980. His background was in biology, but he became fascinated with studying the psychological development of children.

Piaget was a transformational researcher in the field of child developmental psychology. In fact, he is still, to this day, the most cited psychologist in the field.

So what exactly did Piaget do?  How did he change our understanding of human brain development from infancy to adulthood?  In this edition of  Two Guys on Your Head Dr. Art Markman and Dr. Bob Duke talk about Jean Piaget and his impact on the field of cognitive psychology.

The idea of distance conjures up many images in our minds. We might be thinking of how wonderful it will be when we are retired and have time to spend with our loved ones, do some traveling, or play 18 holes of golf on a weekday. Or perhaps when we think of distance, we think of the wars in Iraq and Afghanistan and how far away the conflicts are from us.

For Art Markman and Robert Duke, how we process distance is particularly important, because it clues researchers in to how we think and make decisions as a result of distance.

Who knows what? Essentially, this question is the basis of the complex concept called Theory of Mind – which is very misleadingly labeled. No, it’s not a theory that explains how mind works, as you might assume. It’s a process within our minds that allows us to separate and distinguish between what we know ourselves and what we know that other people know – or don’t know.  It’s a skill that is critical for accomplishing effective social interaction in the world. A better term might be Theory of Other People's Minds.

Dr. Art Markman and Dr. Bob Duke do a wonderful job of explaining and dissecting this important skill in this week’s episode of Two Guys on Your Head. Have a listen and get smarter.

Everybody knows somebody who's familiar with the online dating service experience. It's a fairly common way for people to meet and become romantically involved these days. But how is it different from more traditional dating and courtship?

Dr. Art Markman and Dr. Bob Duke take a crack at online dating in this week’s episode of Two Guys on Your Head.

Living with a mental illness is difficult – not only for the sufferer, but for caregivers, friends and family.

In this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke talk how it can be isolating and disheartening to interact with someone who has depression, dementia or any other mental illness – and they offer some ideas that can help.

One of the struggles in caring for friends and family with mental illness is that we have no idea what we’re really dealing with. Unlike seeing someone with a broken bone, we don’t see mental illness. It's more like a cancer in that it affects the whole family and it lasts for a long time.

Whether we like it or not, time marches on. And as it does, we age. 

One of the most challenging realities for everyone to face in life is that we are all, inevitably, destined to grow old (if we’re lucky, that is).

Aging correlates to a steady decline of functional abilities, both physical and mental. Memory and cognition peak in our early twenties, and we begin a very slow, steady decline of those functions as we near our senior years.  

After age 80, many bodily functions – including brain function – seem to have reached the average limit of their operation. So what can we do to preserve our brains for as long as possible?

Feeling moody lately? Depressed even?

Maybe it’s your job. Maybe it’s the weather. Or maybe it’s the state you live in.

Acting on over a decade’s worth of surveys, a team of researchers have charted relative moodiness state by state across America.

The study measured personality traits, including the so-called big five personality traits test: openness, conscientiousness, extroversion, agreeableness and neuroticism, or OCEAN. So how does Texas measure?

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.)
