👀 Develop your Understanding of this Unit

According to the College Board, "Psychology is the scientific study of behavior and mental processes🧠. This course examines the history of psychology and psychological theories, contemporary perspectives on psychology, and how psychological research is conducted. As scientists, psychologists collect data📊 and make observations about the ways in which humans and animals behave and think in order to understand behavior and mental processes."
"Psychologists use a variety of research methods and designs to conduct their research. These tools help them develop psychological theories about behavior and mental processes. To ensure that their results are valid and reliable, psychologists’ research must adhere to strict ethical and procedural guidelines⚠️. Historical research is the foundation of the field of psychology and has become the basis for the many subfields within psychology that exist today."

🔎 Guiding Questions

  1. How does the methodology of the research affect the outcome of a study?
  2. How do ethical guidelines impact psychological research?

Contextualizing the Unit

Psychology started as a study of the mind 🧠 and behavior which was more based on philosophy. Psychology transformed to more of science when Wilhelm Wundt created the first psychology lab.
Psychology involves the study of mind and behavior.
Psychologists try to study and understand the behavior and mental processes of others. Within psychology, there are various methods and theories to explain those behaviors and mental processes.

Roots of Psychology

You may not think this, but how the mind works was being questioned back when Socrates, Plato, and Aristotle were around. There were two main theories at the time: monism and dualism.
MonismDualism
DefinitionThe mind and body are the same; knowledge grows from experience and is stored in memories.The mind is separate from the body, therefore knowledge is born within you and the mind survives past the body.
Who Believed this theory Aristotle, Francis Bacon, and John Locke believed these. Francis Bacon expanded on this theory and created the idea of empiricism,* realizing that our mind recognizes patterns. Locke thought that the mind was a blank state at birth and coined the theory "tabula rasa." Philosophers Socrates, Plato, and Rene Descartes believed that the mind and body were separate. Rene Descartes additionally believed that thoughts and actions go through "hollow nerves."
*Empiricism—The idea that knowledge comes from experience. Therefore, science should rely on observation and experimentation, which are two research methods we study in this chapter.
