Psych101- Lecture 1 Notes

Psychology is formally defined as the scientific study of the mind and behavior (APA, 2023). It involves the observation of overt behaviors and the investigation of covert mental processes such as thinking, feeling, and desiring.

Origin of the Term: Derived from the Greek words $psyche$ (meaning soul or spirit) and $logos$ (meaning study or knowledge). Historically, it was considered the "study of the soul" before evolving into its modern scientific form.
Evolution: Since the mid- $1800s$ , the field transitioned from philosophical speculation to an empirical science, heavily influenced by physiology and biology.

Common Sense vs. Science: While many believe psychology is just "common sense," common sense is often contradictory and varies based on individual experiences (e.g., contrasting upbringing in single-parent vs. two-parent households).
The Scientific Process: Psychologists rely on systematic observation, experimentation, and evidence-based research to minimize bias and ensure results are replicable.

Theoretical Frameworks: A theory is a set of interrelated concepts that explains or predicts psychological phenomena (APA, 2023). Theories provide the foundation for generating hypotheses and conducting structured research.

Biological Model: Focuses on the physiological and genetic causes of behavior, such as neurotransmitter imbalances or brain structures.
Psychological Model: Focuses on internal mental processes, including the unconscious mind (psychodynamic) and learned environmental responses (behaviorism).
Sociocultural Perspective: Examines how behavior is shaped by social interactions, cultural norms, and community environments.
Biopsychosocial Model: The modern integrative approach that suggests behavior is a result of the interaction between biological, psychological, and social factors.

Gestalt Psychology: Founded on the principle that "the whole is greater than the sum of its parts," focusing on patterns and total experiences.
Psychoanalysis: Developed by Sigmund Freud, it emphasizes the power of the unconscious mind and early childhood experiences in shaping personality.
Behaviorism: Pioneered by John B. Watson, this movement argued that psychology should only study observable behaviors that can be measured, ignoring the "black box" of the mind.

Wilhelm Wundt: Known as the Father of Psychology; he established the world's first psychological laboratory in Leipzig, Germany, in $1879$ .
Edward Titchener: A student of Wundt who developed Structuralism, which aimed to break down conscious experience into its basic elements using introspection.
William James: Author of The Principles of Psychology and founder of Functionalism, which focused on how mental processes help humans adapt to their environment.

Psychodynamic: Modern descendant of psychoanalysis.
Behavioral: Continues to study stimuli and reinforcement.
Humanistic: Focuses on self-actualization and free will (e.g., Maslow and Rogers).
Cognitive: Investigates mental processes like memory, perception, and problem-solving.
Evolutionary: Explains behaviors as adaptations result from natural selection.

Freud (Psychoanalysis): Identifies the id, ego, and superego as components of human psyche.
Pavlov (Classical Conditioning): Demonstrated how organisms learn to associate two stimuli (e.g., the bell and the food for dogs).
Skinner (Operant Conditioning): Focused on how consequences (rewards and punishments) shape behavior.
Bandura (Social Learning Theory): Proposed that people learn through observation, imitation, and modeling.

Psychology is applied in clinical settings (therapy), educational settings (learning optimization), and industry (Industrial-Organizational psychology) to improve productivity and well-being.

Modules will continue into specialized areas including biological rhythms, the mechanics of motivation, the physiology of emotion, and the management of stress.
