THE EVOLUTION OF THE SOCIAL ANIMAL
The law of evolution is that the strongest survives! Yes, and the strongest, in the existence of any social species, are those who are most social.
âUrsula K. Le Guin
My first glance at the phenomenon of Theory of Mind in early human development came twenty-five years ago, when my wife Carol and I were driving from Cincinnati to Hartford, Connecticut, in a rented U-Haul truck. Our fourteen-month-old daughter, Sophie, sat between us in her car seat. I had just finished medical school and we were moving east. I was about to begin my psychiatry training at the University of Connecticutâs Institute of Living. The drive was about fourteen hours, and to keep Sophie entertained we let her eat lollipops.
After her third lollipop, we were still in Ohio. Concerned about her dental hygiene, I said to Sophie, âNo more lollipops.â Sophie looked at me, looked at her mother, took a lollipop, and unwrapped it. Then she covered her eyes with her left hand and, with her right, put the lollipop in her mouth. She was sitting right between us, so what was happening in that remarkable, developing mind of hers? After a few minutes, we realized that she thought that if she couldnât see us, then we couldnât see herâspecifically, we couldnât see her continue to eat her lollipop. At fourteen months, she hadnât yet fully developed Theory of Mind, the capacity to appreciate someone elseâs perspective. Sophie kept eating her candy.
But Sophie would not have covered her eyes unless she thought we had a perspective about her. She covered her eyes so her mom and I would âdisappearâ and she could eat her lollipop in peace. This is critical to ToM: before we can take someone elseâs perspective we first develop a âtheoryâ of how the person is perceiving us. From an evolutionary perspective this makes a lot of sense. Millions of years ago it was much more important to know if someone was looking at you as their lunch than if they were hungry. First comes how they see you, and then comes your perspective of how they feel.
Those of us working in the fields of psychiatry and neuroscience have learned that most children progress gradually toward the developmental milestone called Theory of Mind, or ToM. We canât see another personâs mind, or the way it works. Instead, we create a âtheory,â or an idea of what the other person is thinking and feeling, just as we assume they theorize about our thoughts as well. This is a built-in brain function that we ordinarily take completely for granted. For instance, you see a woman standing on the corner waiting for a cab. If itâs a cold, rainy night you can theorize how frustrated she must feel as cabs pass her, already occupied. Go a step further with this scenario. You see a man move a few feet in front of this woman and stick his hand out for a cab. You can theorize quite easily how this action will affect the womanâs brain and emotions. Your own Theory of Mind is what first makes you aware that this act is inappropriate and even downright aggressive; you can theorize that this act will anger another. Your ToM will also enable you to see how others would perceive the manâs action.
The vast majority of people develop this capacity between the ages of eighteen months and five years. Once developed, we use it all the time, so fluidly and naturally it just âhappens.â In fact, having never heard the term or the idea, most of us are not aware we are using Theory of Mind at all.
But we are.
As social creatures, a fully functional ToM is fundamental to our ability to get along well with other humans in the world. When we wonder if someone likes us, or doesnât like us, if someone is angry with us, if we are admired, envied, despised, lovedâthatâs ToM at work. We âtheorizeâ about the waitress serving us food if there is too long a delay in taking our order, or about the doctor who seems to be taking too long to return to the examining room, or about the person we hope will say yes to a first date. If you ever wonder about such things, then congratulations, your ToM is in sound working order. Throughout this book, youâll learn how to use it to your advantage, but letâs first take a look at how we discovered its very existence.
THEORY OF MIND AND EMPATHY If you ask most people what empathy is, they might have a hard time explaining it. But they will know instinctively how it feels, on both the giving and receiving end. As a basic definition, empathy involves one personâs ability to appreciate the emotions another person feels, often from a similar life experience. For instance, if your friendâs dog died, and youâve also had that experienceâor another experience of losing a beloved companionâthen you can empathize with his pain and grief, and vice versa. This common experience has the potential to then bind you and your friend together as he recognizes that you understand and care about what heâs going through. It calms the brain to know a person really âgetsâ how you feel. You feel less alone and more connected when others can relate to your situation.
Empathy is not possible without a foundation of Theory of Mind. The very first step toward empathy is the ability to appreciate on a basic level that another person has thoughts and feelings separate from your own. A person who canât follow the emotional component of communication canât experience or practice empathy. Empathy lets people know that they are not alone, that another person âseesâ what they are experiencing. Being seen like this can help a person bear even the most unbearable loss or enhance the pleasure of even the smallest success.
Unfortunately, a person can have ToM and not have empathy. In extreme cases, weâre talking about a person who is likely to have sociopathic tendencies, which is fortunately quite rare. In less sinister cases, ToM can be exploited to get us to do things we may not have thought of doing, like buying a warranty on a new computer, or adding on the expensive deluxe sound system in a new car. Really good salespeople can tap into our ToM, not lying to us but exploiting our fears and desires. Has that ever happened to you? Have you purchased something that, in retrospect, you wish you hadnât? At the time it made a lot of sense because your own ToM may have been subtly manipulated by a master!
The concept of Theory of Mind was first presented by two psychologists, David Premack and Guy Woodruff from the University of Pennsylvania. For their groundbreaking study published in the Journal of Behavioral and Brain Science in 1978, they investigated whether chimpanzees had the ability to attribute intent or mental state to others. The scientists observed chimps looking at a video of a human actor struggling with challenges such as being locked in a cage, being unable to reach food, or shivering from cold. The chimps were then given photographs of the solutions to each of these problems, and they consistently selected the correct remedy, as if they had been the ones locked in a cage, reaching for food, or shivering from cold. Premack and Woodruff showed that a chimpanzee can take the perspective of another animal. The paper was titled âDoes the Chimpanzee Have Theory of Mind?â
Humans take other peopleâs perspectives all the time, but it was Premack and Woodruffâs work that ushered in a brand-new focus of research: how, when, and why do we develop the ability to assign mental states to ourselves as well as to others? In 1983, University of Salzburg psychologists Josef Perner and Heinz Wimmer built on Premack and Woodruffâs work and created tests called âfalse-beliefâ tasks for children. One of the classic examples they developed to demonstrate ToM is called the Sally-Anne âunexpected locationâ task. Children being given this test were told the story of two characters, Sally and Anne. Sally has a basket and Anne has a box. Sally also has a marble. Sally puts the marble in her basket, and then she leaves the room. While sheâs gone, Anne takes the marble out of Sallyâs basket and puts it in her box. Soon afterward, Sally returns.
In the test, the child is asked where Sally will look for her marble when she comes back into the room. Very young children typically respond by saying that sheâll look in Anneâs boxâafter all, weâve just seen Anne put it there. They donât understand yet that Sally would still believe that the marble is where she left it, as she hadnât seen Anne move it. From the young childâs point of view, if he or she saw it, then everyone saw it. This was the very same action we witnessed in our daughter Sophie with the lollipops. The young childâs perspective is the same as everyone elseâs, and everyone elseâs the same as the childâs. A child who says Sally will look for the marble in Anneâs box has not yet developed Theory of Mind.
Two-, three-, and four-year-old children are just beginning to form ToM, this ability to take anotherâs viewpoint. They donât yet understand that Sallyâs thinking is separate from Anneâs and that their own thinking is separate from everyone elseâs. At around age five, that begins to change. And by the time children are six or seven, they are more likely to say that Sally will look in the place she left the marbleâin her basket. By this time, they are fully aware that other people have their own distinct thought processes and unique perspectives. And crucially, ToM brings with it an ability to predict other peopleâs behavior. This combination of taking anotherâs perspective and anticipating othersâ behavior is what drives our relationships.
Without thinking about it consciously, most people assume that everyone has the ability to take another personâs perspective, to have an active and intact ToM. In fact, we expect others to be interested in what weâre thinking or feeling, and to give us a sign that theyâre interested. When someone doesnât meet this expectation, we tend to think that thereâs something wrong with him or her or, even worse, that something might be wrong with us. In reality, however, ToM abilities exist on a spectrum. Some people have strong abilities to take anotherâs viewpoint; others less so.
The lack of ToM becomes very obvious, and even uncomfortable, when we interact with people who have not developed this ability, who have psychiatric or brain conditions such as autism, dementia, or various types of neurological damage. These people may behave in ways that seem insensitive, lacking in interest or concern for others. But what we know is that these people are not being oppositional in response to our feelings. Rather, they are oblivious to our feelings and that we might have any feelings at all. But once we become aware of their lack of ToM, weâre more likely to feel empathy for them.
It seems almost inconceivable that humans arenât born with an intact ToM. Itâs the...
