Accomplishing this is much easier said than done. People perceive each other based on prior experiences, cultural values and beliefs. Psychologists often focus on the motives steering a person's behavior. They look for connections between things that happen and how people respond. Much like mystery buffs that believe motive in a whodunit is as important as who did it. Psychologists want to know, why do some, but not all abused children become abusive adults? How does a brain tumor affect someone's personality? Does watching too much violence on television lead to violent behavior?

It was not until the end of the nineteenth century that the Psychology community went beyond just thinking about human nature and

" Charles Darwin, seen as the founder of evolutionary psychology believed that the best-adapted traits are the ones that will be passed along from one generation to another in species. Creatures with less adapted traits will die out before they can reproduce, so their poorly adapted traits will eventually disappear from the population" (19).

Not everything can be directly observed in a laboratory. Human activities, such as, reasoning, creating, or dreaming are private; we assume they happen, but we can't see them. Because human beings are so complex and multi-layered, physiologists have theories for just about everything from learning to child development, from memory to mental illness. Personality theories try to explain why people are the way they are; development theories look at how children become adults. It is theorized that mental illness is a result of painful childhood experiences. Psychologists wonder and explore what types of childhood experiences have the most impact on people, and at what age does it actually make a difference.

In Joni Johnson, PhD's commentary, " A Little Psychological Insight", states that

There are two types of reasoning deductive and inductive. Deductive reasoning is a way of thinking in which one logically draws a conclusion based on one or more statements or premise. Inductive reasoning is when a conclusion is made based on available information and past experiences.

The cerebral cortex, divided into two hemispheres and eight lobes (four for each hemisphere) is the headquarters of human behavior. The brain and the spinal cord make up the Central Nervous System (CNS) and the Peripheral Nervous System (PNS) is made up of neurons connecting the CNS to the body. As evolution progressed so did the process and content of human consciousness.

There are different levels of consciousness: non-conscious, handles information that is not represented in consciousness or memory but critical to bodily and mental activity, such as data needed to breath and control your heartbeat. Preconscious, stores data you don't need right now but readily accessible if something calls your attention to it, for example, if someone asks what you had for dinner last night and you can answer correctly. The subconscious is where information that is not currently in your consc
