Definition of Psychology

  • Psychology refers to the scientific study of the mind and behavior.

  • Psychologists utilize the scientific method to acquire knowledge.

    • Hypothesis: A tentative explanation for how or why something happens, fitting within a scientific theory.

    • Theory: A broad explanation supported by evidence regarding some aspect of the natural world.

  • Psychological science is empirical, based on measurable and observable data.

    • For example, asking about bird happiness rather than directly measuring it due to the untestability of happiness.

Major Themes in Psychology

  • Science is limited to measurable phenomena; thoughts, as experienced, are neither matter nor energy, limiting scientific understanding.

  • The late 1800s marked the establishment of psychology as a separate academic field, previously explored by philosophy.

  • Psychology merges biology, influenced by social interactions, making it both a natural and social science.
