Psychology can be defined as the systematic study of mental processes, couple with behaviors, and experiences (Kalat, 2011). There are many ways in examining, mental processes and behaviors among people, and therefore psychologist uses different perspectives to understand how human beings, think, act, and behave. Some psychologist uses one perspective to analyze behaviors, and other uses a multidimensional approach. Carter & Seifert (2013) identified 7 major perspectives that are used to study people’s behavior, and mental processes. These perspectives are the biological, evolutionary, psychodynamic, behavioral, humanistic, cognitive, and the sociocultural perspective.
The biological perspective looks at how the environment and physical causes influences behavior. In the biological perspective, neuroscience plays a crucial role in explaining how the brain and the nervous system influence behaviors. Neuroscientist describes how the brain process thoughts, emotions, feelings, and how the physical body is driven by these mental processes. This branch of psychology, engages in a variety of research such as the study of genetics, brain cells, and the function of the brain across a period of time. This is done using positron emission tomography (PET). This technique is used with radio active glucose to indicate areas of activity in the brain. Another technique that is done to conduct brain research is functional magnetic resonance imaging (IMR). It uses powerful magnets and radio equipment that provides comprehensive pictures of soft tissues of the brain.

...ses influences behavior. The evolutionary perspective explains, how evolution explains mental processes. The psychodynamic perspective assumes that human behaviors are driven by unconscious forces. The behavioral perspective is primarily concerned with learned behaviors. The humanistic perspective emphasizes on personality growth. The cognitive perspective examines our internal thought processes. Finally, the sociocultural perspective compares human behaviors to other cultures, and social settings. There are many ways to examine human behaviors, and these perspectives can help to explain these behaviors, and come up with possible solutions.
