    Study Notes

    General Psychology Study Notes

    • Psychology is the scientific study of behaviour, mental processes, and brain functions.
    • Psychology's roots lie in philosophy and the natural sciences.
    • Early attempts to study the mind, such as introspection, proved unsatisfactory due to the subjectivity involved in self-observation.
    • Psychological scientists now use experiments and other systematic methods to measure and explain behaviour.
    • Psychology encompasses various perspectives, including biological, evolutionary, cognitive, developmental, social, and personality, as well as clinical psychology.
    • Key methods in psychology include descriptive methods, such as case studies, surveys, and naturalistic observations, correlational methods, and experimental methods.
    • The scientific method involves formulating hypotheses, collecting data, analyzing results, and drawing conclusions.
    • Replication of studies is crucial for verifying findings and building reliable knowledge.
    • Key concepts include:
      • Consciousness
      • Cognition
      • Behaviour
      • Neuroscience
      • Nature vs. nurture
      • Memory
      • Learning
      • Psychological disorders
