Are you a mover, a perceiver, a stimulator, or an adapter? Modes of thinking can be understood in terms of how the top and bottom—rather than right and left—parts of the brain interact.

It is possible to examine any object—including a brain—at different levels. Take the example of a building. If we want to know whether the house will have enough space for a family of five, we want to focus on the architectural level; if we want to know how easily it could catch fire, we want to focus on the materials level; and if we want to engineer a product for a brick manufacturer, we focus on molecular structure.
Similarly, if we want to know how the brain gives rise to thoughts, feelings, and behaviors, we want to focus on the bigger picture of how its structure allows it to store and process information—the architecture, as it were. To understand the brain at this level, we don’t have to know everything about the individual connections among brain cells or about any other biochemical process. We use a relatively high level of analysis, akin to architecture in buildings, to characterize relatively large parts of the brain.
To explain the Theory of Cognitive Modes, which specifies general ways of thinking that underlie how a person approaches the world and interacts with other people, we need to provide you with a lot of information. We want you to understand where this theory came from—that we didn’t just pull it out of a hat or make it up out of whole cloth. But there’s no need to lose the forest for the trees: there are only three key points that you will really need to keep in mind.
First, the top parts and the bottom parts of the brain have different functions. The top brain formulates and executes plans (which often involve deciding where to move objects or how to move the body in space), whereas the bottom brain classifies and interprets incoming information about the world. The two halves always work together; most important, the top brain uses information from the bottom brain to formulate its plans (and to reformulate them, as they unfold over time).
Second, according to the theory, people vary in the degree that they tend to rely on each of the two brain systems for functions that are optional (i.e., not dictated by the immediate situation): Some people tend to rely heavily on both brain systems, some rely heavily on the bottom brain system but not the top, some rely heavily on the top but not the bottom, and some don’t rely heavily on either system.
Third, these four scenarios define four basic cognitive modes— general ways of thinking that underlie how a person approaches the world and interacts with other people. According to the Theory of Cognitive Modes, each of us has a particular dominant cognitive mode, which affects how we respond to situations we encounter and how we relate to others. The possible modes are: Mover Mode, Perceiver Mode, Stimulator Mode, and Adaptor Mode.
Systems, Not Dichotomies
We use what researchers have learned to present a new theory of brain function that hinges on how the top and bottom parts of the brain interact. But we do not try to characterize the top and bottom parts of the brain in terms of a simple dichotomy or set of dichotomies, which was exactly what was done with the existing and well-known division of the brain into two halves: namely the left versus the right, the dominant pop-culture brain story of the last few decades. You have probably heard of this theory, in which the left and right halves of the brain are characterized, respectively, as logical versus intuitive, verbal versus perceptual, analytic versus synthetic, and so forth. The trouble is that none of these sweeping generalizations has stood up to careful scientific scrutiny. The differences between the left and right sides of the brain are nuanced, and simple, sweeping dichotomies do not in fact explain how the two sides function.
