Psychology is the scientific study of behavior and mental processes.
To be scientific, one must use the empirical approach, be unbiased, and utilize critical thinking skills.
Goals of Psychology: Describe, explain, predict, and control behavior.
Psychology originates from structuralism, which describes the mind by breaking thoughts down into their most basic elements. This idea was developed by Wilhelm Wundt (1832-1920). Introspection was his favored method of researching psychology.
Another foundation of psychology is functionalism, which is the understanding of the purpose of thoughts and behavior in an individual’s adaptation to the environment. This incorporates the idea of natural selection. This idea was founded by William James (1842-1910).
Structuralism is describing. What is the mind?
Functionalism is explaining. What is the mind for.
Behaviorism emphasizes the scientific study of observable behavioral responses and the environments that determine those responses. It was established by John B. Watson (1878-1958).
He is most famously known for his famous Little Albert Experiment.
In short the highly controversial experiment conditioned baby “Albert” to fear a white rat. How did they do this? Well, they presented Albert with the white rat. He showed no fear of it. Then they would present the white rat followed by a loud startling sound from behind him. The sound would scare little Albert, and he would react with crying and fear. Eventually, Albert was conditioned to associate the white rat with the noise and the fear until eventually Albert feared the white rat in the absence of the noise. He just came to fear the rat because it was normally accompanied by the terrifying sound.
There are seven contemporary approaches to psychology today:
Biological: Human and animal behavior is seen as the direct result of events in the body.
Example: Measuring sweat on your skin when you lie.
Behavioral: Emphasizes the scientific study of observable behavioral responses and the environments that determine those responses.
The idea that you can modify behavior using various rewards and punishments. (x)
Psychodynamic: Mental and behavioral problems are caused by conflicts between acceptable behavior and unacceptable, unconscious desires.
Founded by Sigmund Freud (x)
Humanistic: Emphasizes free will, self-actualization, and human nature as growth-seeking experiences and motivations for behavior.
Carl Rogers and Abraham Maslow (x, x)
Cognitive: Study how we think, remember, store, and use information from our environment during a vast array of mental processes.
Example: How do we learn language? What is intelligence?
Evolutionary: Focus on natural selection, adaptation, and the evolution of behavior. Causes of behavior are attributed to those that lead to greater reproductive success.
Example: Evolutionary theory of mate selection
Sociocultural: Emphases social interactions and cultural determinants of behavior and mental processes–specifically ethnicity, religion, occupation, and socioeconomic status as predictors of behavior.
Example: Does socioeconomic status affect your health?
Remember the scientific method?
Psychology uses it as well! Remember: Psychology is a science!
