Foundations of Evolutionary Psychology

  • Edited by Charles Crawford, Dennis Krebs

Evolutionary psychology is concerned with the adaptive problems early humans faced in ancestral human environments, the nature of psychological mechanisms natural selection shaped to deal with those ancient problems, and the ability of the resulting evolved psychological mechanisms to deal with the problems people face in the modern world. Evolutionary psychology is currently advancing our understanding of altruism, moral behavior, family violence, sexual aggression, warfare, aesthetics, the nature of language, and gender differences in mate choice and perception. It is helping us understand the relationship between cognitive science, developmental psychology, behavior genetics, personality, and social psychology.

Foundations of Evolutionary Psychology provides an up-to-date review of the ideas, issues, and applications of contemporary evolutionary psychology. It is suitable for senior undergraduates, first-year graduate students, or professionals who wish to become conversant with the major issues currently shaping the emergence of this dynamic new field. It will be interesting to psychologists, cognitive scientists, and anyone using new developments in the theory of evolution to gain new insights into human behavior.

After many months of work (and we hope many new neurons and stronger synapses in our brains), we have just released our inaugural report on the emerging Brain Fitness Software Market, Brain Fitness Software the first to define the brain fitness software market and analyze the size and trends of its four customer segments. We estimate the size of the US brain fitness software market at $225M in2007, up from $100m in 2005 (50% CAGR). The two segments that fueled the market growth: consumers (grew from $5m to $80m, 300% CAGR) and healthcare & insurance providers (grew from $36m to $65m, 35% CAGR).

Highlights from The State of the Brain Fitness Software Market 2008 report include:

1) 2007 was a seminal year for the US Brain Fitness software market, which reached $225 million in revenues – up from an estimated $100 million in 2005.

2) Over 20 companies are offering tools to assess and train cognitive skills to four customer segments: consumers; healthcare and insurance providers; K12 school systems; and Fortune 1000 companies, the military, and sports teams.

3) The Nintendo Brain Age phenomenon has driven much of the growth. The consumer segment grew from a few million in 2005 to an estimated $80 million in 2007.

4) There is major confusion in the market, so education will be key. Users and buyers need help to navigate the maze of products and claims.

5) Over 400 residential facilities for older adults have launched computerized “brain fitness centers.” Sales to the healthcare and insurance provider segment grew from $35 million in 2005 to an estimated $65 million in 2007.

6) More than five programs have shown results in randomized controlled trials. Cognitive functions that can be trained include: visual and auditory processing, working memory, attention, and decision-making.

7) A product has obtained 510(k) FDA clearance for rehabilitation of stroke and Traumatic Brain Injury patients. Another product is being used by a growing network of ADHD specialists.

8) Large-scale, fully-automated cognitive assessments are being used in a growing number of clinical trials. This opens the way for the development of inexpensive consumer-facing, baseline cognitive assessments.

9) The potential for K12 Education remains largely untapped due to limited research linking cognitive training to academic performance.

10) Companies, sports teams and the military are finding opportunities to improve productivity. The aging workforce will make this a must.

The report tracks developments at over 20 public and private companies offering tools to assess and train brain functions and provides important industry data, insights and analysis to help investors, executives, entrepreneurs, and policy makers navigate the opportunities and risks of this rapidly growing market. The report discusses the implications of cognitive science on healthy aging and a number of disorders such as attention deficits, dyslexia, stroke and traumatic brain injury, schizophrenia, autism, mild cognitive impairment, and Alzheimer’s disease. The report also provides information and frameworks to help institutional buyers make informed purchase decisions about brain fitness programs.

A few accolades for the report:

"Finally, an insightful and complete overview of the science, companies and trends in the brain fitness field. A must-read for everyone offering products and services to boomers and elders."
- Gloria Cavanaugh, former President & CEO of the American Society on Aging and founding Board member of the National Alliance for Caregiving.

"This groundbreaking report provides a definitive overview of the emerging Brain Fitness industry --- an important category to watch for every gaming and healthcare executive and investor. SharpBrains' comprehensive report defines a clear scope for the market and also charts its evolution, path and key trends."
- Tim Chang, Principal at Norwest Venture Partners.

"Brain health and function is becoming a top priority in our society. This is as true for school children as it is for corporate executives or aging baby-boomers. It is a typical misconception about the brain that there is only one general intelligence to care about. It has been shown that there are many different cognitive abilities each of which may be trained systematically. While physical exercise increases the rate of formation of new nerve cells, mental exercise promotes their survival. It is in this context that an explosion of new "brain-training" software modalities have been developed.
The 2008 State of the Brain Fitness Software Market report is a timely analysis of the status of this new and emerging market. Preliminary results from scientific investigations evaluating several of the programs suggest not only short-term improvement in the trained skills, but a more long lasting and extended response spanning related mental functions. The review clearly states that the impact of mental training on brain aging and dementing disorders remains unknown, but it profiles each approach regarding degree of scientific scrutiny, market segment, modality, and specific parameter being trained. Healthcare and psychology professionals will benefit immensely from this state of the art, comprehensive overview and insightful analysis."

Dr. Adrian Preda, our newest Expert Contributor, writes today the first in a series of thought-provoking articles,physical exercise for the brain challenging us to think about physical exercise as the best and most unappreciated form of "brain exercise". A superb article.

And one thing is clear, he points out: "the brain really likes it when it’s asked to be “active”. Passive audiences, which are spoon fed information, score less well when tested on retention and understanding of the presented material than audiences that were kept engaged through the process."

So, will you write a comment below and contribute to an engaging conversation? Thoughts? reactions? questions?
-------------------------

Don’t ignore plain old common sense.

Brain Lessons Part 1

-- By Adrian Preda, M.D.

Let me start with a list of common biases: expensive is better than cheap, free is of dubious value (why would then be free?), rare is likely to be valuable, and while new is better than old, ancient is always best. Which explains a common scenario that is reenacted about twice a week in my office. It starts like this: a patient shows me a fancy looking bottle of the brain supplement of the week: ancient roots with obscure names mixed together in another novel combination which you can exclusively find in that one and only store (rarity oblige!). And not to forget: it ain’t cheap either! Of course, there it is, the perfect the recipe for success: ancient yet new, rare and expensive. It got to be good! But is it, really?

The problem with recommending physical exercise when it comes to brain fitness is that is doesn’t have any of the glamour traits I have just mentioned: it’s been around for a long time – so there is nothing new and exciting about it, there is no fancy name or exclusive label marketing it and, worst of all, it is as cheap as cheap can be: not only free but also available in unlimited supplies.

So when I tell my patients that the single most important thing they need to pay attention to when it comes to keeping their brain in shape is exercise I invariably get a “really, and you needed to get an MD to tell me this?” look. Nowadays everybody seems to know that physical exercise is good for the brain. Big news they say. And they needed to study that? Duh?

For most it’s no big surprise to find out the people who have a physically active life style have a decreased risk of Alzheimer’s dementia or the number of blocks one walks everyday appears to inversely correlate with the rate of cognitive decline later in life. It sort of makes sense to assume that has to be the case. Here are a few well established facts.

First of all, regular physical exercise correlates with improved health – meaning less risk for high blood pressure, metabolic problems (cholesterol, lipids and glucose dysregulation) and weight gain, which is all good for the brain. A healthy brain needs a healthy environment, doesn’t it? Or to put it in a slightly different way: an unhealthy environment would not be good for the brain, wouldn’t it? I think we would all agree on that one.

Now, would a healthy environment not only protect but also improve the brain structure and performance? Would it also promote the growth (if possible) of the brain? The answers to such questions are less obvious. For example we know that not all healthy people end up with “good brains”. Well, why is that? Specifically, when it comes to physical exercise then are there such things as a minimal dose of exercise that can result in positive brain effects? And is there a maximal or “toxic” dose of physical exercise which may in fact hurt the brain? Is all physical exercise equally good for the brain or do different physical exercise routines differ in terms of their brain effects? I put those questions on the table and the chance is that I got the “duh” people’s attention.

First, let me say that to scientists the physical exercise question is no different that any other scientific question. Scientists tend to be a skeptical bunch and as such they like to always point out that correlation does not necessarily imply causation. Take the old active people who didn’t get Alzheimer’s example. One possibility is that their consistent exercising keeps them from getting Alzheimer’s. But what is it that got them to exercise more in the first place? Could it be that their brains were equipped with the sort of gear that gets one excited about pushing themselves a bit, which would then result in these fellows being more prone towards doing physical things to start with? Then they will be more active physically but that is because their brains were wired differently from the gecko and that, in itself, might have decreased the risk of Alzheimer’s dementia. In a situation like this physical exercise is what scientists call a confounder – i.e. a concomitant but not necessarily casual event that can falsely be seen as a cause resulting in the final effect.

How can one figure this one out? Over the next few columns we will look together at ways of answering apparently not so straightforward questions about physical exercise and the brain.

Now, to begin I will like to make this column, to whatever extent possible, an interactive forum. And that is as it turns out that the brain really likes it when it’s asked to be “active”. Passive audiences, which are spoon fed information, score less well when tested on retention and understanding of the presented material than audiences that were kept engaged through the process. So, in the spirit of “engagement” I will start by asking a few questions about what is important when it comes to the effects of physical exercise on the brain. Depending on what your answers will be we will then take it to the next level, i.e. critically examine the research evidence about specific brain effects of different types of physical exercise.

So, consider which of the following possibilities will get you convinced that physical exercise is good for the brain. Would you be convinced if exercise has been shown to:

1. Increase longevity (as a better brain should make us live longer, shouldn’t it?)
2. Decrease the risk of Alzheimer and other types of dementia
3. Decrease the risk of “normal” age related memory loss or cognitive decline
4. Increase one’s ability to problem solve
5. Decrease one’s risk for depression or anxiety.
6. Improve one’s memory, concentration and attention.
7. Improve one’s ability to feel consistently happy.
8. Increase the number of nerve cells or nerve cells connections in the brain?
9. Correlate with higher education
10. Correlate with higher social economic status?
11. Chemicals released during exercise were shown to promote nerve cell growth?
12. Exercise would “correct” chemical abnormalities reported in mental or brain illness?

I am looking forward to your answers. Please do not hesitate to come up with other questions or hypotheses. We’ll make this into an exercise about how to think about physical exercise. Another form of exercise that might be good for the brain.

RopeA quick teaser: Imagine you are one of 120 people in a room. Each person in the room is given two lengths of rope and told to chose two of his or her four rope-ends at random and to tie them together. Then each person is told to tie the remaining two rope-ends together.

Then, we count up the loops of rope. How many should there be?

SOLUTION:

When each person prepares to choose his second rope-end, we note that one of the available three rope-ends is the other end of the rope he is holding, and the other two are from the other length of rope.

He is equally likely to pick any of these three rope-ends, so there is a one-in-three chance that he will create a loop at this time, and a two-in-three chance that he will instead simply join two ropes into one. He'll be left with one rope (plus possibly a loop). Either way, he'll tie his final rope into a loop in the second step.

Therefore, we expect one third of the people (40) to have made two loops, and the remaining two-thirds (80) to have made one, for a total of (40 x 2 + 80 = ) 160 loops.

Placebo effect, mind hacksIn the ETech panel a few days ago, we discussed some futuristic and some emerging ways in which we can "hack our minds", mostly from a technology point of view.

Neither myself nor the other panelists thought of suggesting the most obvious and inexpensive method, proven in thousands of research studies.

The secret compound?: Belief. Also called "the placebo effect". Let's see what Wikipedia says:

- "Placebo effect is the term applied by medical science to the therapeutic and healing effects of inert medicines and/or ritualistic or faith healing practices. When referring to medicines, a placebo is a preparation which is pharmacologically inert but which may have a therapeutic effect based solely on the power of suggestion."

- "The placebo effect occurs when a patient takes an inert substance (sometimes called a "sugar pill") in conjunction with the suggestion from an authority figure or from acquired information that the pill will aid in healing and the patient’s condition improves."

Now, via MindHacks:

- "Bad Science looks at how the strength of the placebo effect has changed over time for different drug trials, suggesting that as our cultural beliefs change, the effectiveness dummy treatments might also change depending on how they're presented."

- "Similarly, The New York Times have just published a brief article on a new study that found placebos described as costing $2.50 a dose are more effective pain killers than those presented to participants as costing 10 cents a dose."

Conclusion: the placebo effect is real, and it can benefit our health. A few implications to ponder:

- First, how do we prevent other people from selling us stuff that only works based on the placebo effect? the therapeutic value is in us, not in the stuff.

- Once we decide to do something, shouldn't we try to "placebo" ourselves in order to get the most of it? we may not control how our beliefs affect us, but, can we manage our beliefs?

Daniel Goleman requires no introduction. Personally, of all his books I have read, the one I found most stimulating was Destructive Emotions: A Scientific Dialogue With the Dalai Lama, a superb overview of what emotions are and how we can put them to good use. These days he also offers a series of interviews including a great one with George Lucas on Educating Hearts and Minds: Rethinking Education.

We are honored to bring you a guest post by Daniel Goleman, thanks to our collaboration with Greater Good Magazine, a UC-Berkeley-based quarterly magazine that highlights ground breaking scientific research into the roots of compassion and altruism. Enjoy!

The Power of Mindsight

How can we free ourselves from prisons of the past?

-- By Daniel Goleman

When you were young, which of these did you feel more often?

a) No matter what I do, my parents love me;

b) I can’t seem to please my parents, no matter what I do;

c) My parents don’t really notice me.

The answers to such questions don’t just reveal truths about our childhood. They also tend to predict how we act in our closest relationships as adults.

Our childhood shapes our brain in many ways—and so it determines our most basic ways of reacting to others, for better and for worse. When parents consistently practice empathy toward a child—that is, they tune in to the way that child views and feels about her world—they help instill in that child a sense of security and an ability to empathize with others later in life. But when parents act dismissively toward a child, they can make it harder for that child to be in touch with her emotions and connect with other people.

Daniel Siegel has done years of research to support these conclusions. Siegel, a psychiatrist at the University of California, Los Angeles, founded the field of “interpersonal neurobiology,” which explains the brain basis for our habits of bonding with others. His research shows how we can overcome emotional disadvantages that might have arisen from difficult childhoods.

“Let’s say a child’s angry and is starting to throw something,” says Siegel. A dismissive parent focuses on stopping the behavior, instead of acknowledging the emotion that might have caused the child to throw that object. “The emotion behind the behavior is not recognized. It’s not seen.”

If parents consistently fail to acknowledge and discuss the connections between a child’s behavior and her emotions, says Siegel, the child won’t gain any insight into her own thoughts and feelings, nor will she appreciate other people’s emotional states. Siegel calls this ability “mindsight,” and he argues that it serves as the basis of self-awareness and empathy, while also predicting what kind of parent that child will grow up to be.

However, Siegel points out that actual childhood experiences are less important than how we make sense of those experiences. In other words, we can learn to think about our experiences in ways that can help us overcome them. This is good news for parents who had miserable childhoods. In fact, it’s never too late for adults to develop mindsight, because we can always rethink our childhoods, gain a new understanding of them, and thus avoid repeating the mistakes of the past with our own children.

When I spoke with Siegel recently, he described how he watched a 90-year-old woman in therapy learn ways of talking about her own and others’ emotions, after a lifetime of denying them. The process, he says, started by revisiting her childhood, when “she would come home sad and she would be punished for not being more upbeat,” which created a person who was good at focusing on behavior and bad at perceiving feelings. But when Siegel helped this woman see how her habits of mind were shaped in childhood, she was able to free herself from their grip.

“You can make sense of what has happened to you,” says Siegel, “and become freer from these prisons of the past that really constrain so many people.”

Other scientists have conducted research that validates Siegel’s ideas. For example, Joseph LeDoux, a neuroscientist at New York University and perhaps the world’s leading expert on emotional memory, has found that whenever we bring to mind a strong emotional memory and think about it differently than we had before, it actually gets chemically recorded in the brain in a whole new way. A process of introspection can actually change the way that memory is imprinted on our brains, providing a neural basis to lasting changes in our behaviors and habits of mind.

And just as our relationships with our parents shape our neural circuitry, so too can our adult relationships help rewire us for connection and security. Siegel points out that our relationships as adults can “reparent” us. For example, if someone who was not given a secure base in childhood marries someone who was, research shows that that shaky person will gradually become more secure.

“Research absolutely demonstrates that if you take the time to make sense of what happened to you, then you can free yourself up to develop your own sense of security inside of you, and also have children who have a secure attachment to you,” says Siegel. It’s a hopeful message: No matter what happened to us in childhood, we never stop growing.

Goleman’s full conversation with Daniel Siegel can be heard as part of the audio series Wired to Connect: Dialogues on Social Intelligence, available through More than Sound Productions.
