Study Notes

Definition of Psychology

Psychology combines the Greek words "psyche" (mind, soul, or spirit) and "logos" (study, knowledge, or discourse)
Modern psychology is generally defined as the scientific study of behavior and mental processes.
Behavior refers to observable actions and reactions (talking, facial expressions).
Mental processes encompass internal, covert activities (thinking, feeling).

Goals of Psychology

Description: Observing behavior and noting all aspects
Explanation: Determining reasons for observed behavior
Prediction: Anticipating future behavior
Control: Modifying behavior from undesirable to desirable

Historical Background and Major Perspectives

Psychology is relatively young (approximately 125 years old), beginning as a formal science around 1879.
Wilhelm Wundt established the first psychology laboratory in Leipzig, Germany.
Psychology has evolved through several schools of thought, including:
- Structuralism (focus on structure of mind)
- Functionalism (focus on functions of mind)
- Gestalt Psychology (focus on the whole mind)
- Psychoanalysis (focus on the unconscious mind)
- Behaviorism (focus on observable behavior)

Modern Schools of Thought

Psychodynamic perspective: Emphasizes unconscious forces, conflicts, and instinctual energy.
Behavioral perspective: Highlights the role of learning experiences in shaping behavior.
Humanistic perspective: Focuses on human values, free will, and potential for growth.
Cognitive perspective: Emphasizes mental processes like thinking, remembering, and problem-solving.
Biological perspective: Examines the physical basis of behavior, feelings, and mental processes.
Socio-cultural perspective: Recognizes the influence of social and cultural factors.

Research Methods

Scientific method: Reduces bias in measuring data.
Theory: Integrated principles that describe and explain observations.
Case study: Examining specific individuals, not easily generalized.
Survey: Gathering data from a large group of people.
Correlational research: Identifying relationships between variables.
Experimental research: Studying cause-and-effect relationships by manipulating one or more factors. (independent variables) while keeping all other factors (constant)

Steps in Scientific Research

Defining the problem: Identifying a noticeable issue
Formulating a hypothesis: Educated guess about the issue's explanation
Testing the hypothesis: Collecting data to either support or reject the hypothesis.
Drawing conclusions: Generalizing implications from the collected data
Reporting results: Sharing findings so others can learn and build on the research.
