Study Notes

What is Psychology?

Psychology is the scientific discipline devoted to the study of behavior and mental processes. It integrates various theoretical frameworks and methodologies to gain a comprehensive understanding of how people think, feel, and act. By examining both observable behaviors and internal mental states, psychology aims to unravel the complexities of human nature and offer insights that can enhance our understanding of individuals and groups.

Psychological Perspectives

Psychoanalysis: This perspective, founded by Sigmund Freud in the late 19th century, focuses on the significance of unconscious drives, desires, and conflicts in shaping human behavior. Psychoanalysis led to the development of psychodynamic theories that underline the importance of early childhood experiences and the influence of repressed memories on current behavior and emotional states.
Behaviorism: Originating in the early 20th century, behaviorism concentrates on observable behavior rather than internal mental states. It posits that behavior is shaped and maintained by external influences, primarily through the mechanisms of rewards and punishments. As such, it forms the foundation of contemporary behavioral psychology and has practical applications in areas such as therapy and education.
Cognitive Psychology: Emerging in the 1950s and 1960s as a response to behaviorism's limitations, cognitive psychology emphasizes the role of mental processes in influencing behavior. This perspective examines how people perceive, think, remember, and learn, paving the way for key advancements in understanding human cognition as well as the development of cognitive therapies.
Humanism: In contrast to the deterministic views of psychoanalysis and behaviorism, humanistic psychology focuses on individual potential and self-actualization. It emphasizes personal growth, self-awareness, and the inherent goodness of individuals, suggesting that people possess the ability to make rational choices and develop to their fullest potential when given the right conditions.

Research Methodology

Theory: This foundational aspect of psychological research aims to formulate overarching explanations for observed phenomena. An example of such a theory is the hypothesis that suggests people might have a higher attraction to individuals who are different from themselves, encapsulated by the expression "opposites attract."
Hypothesis: Within the framework of this theory, specific hypotheses can be developed. For instance, researchers might propose that experiments will empirically demonstrate a preference for individuals who exhibit differing characteristics, rather than those who are similar.
Independent Variable: This refers to the manipulated element within the study, specifically focusing on the similarity or difference among individuals being assessed for attraction or preference.
Dependent Variable: The dependent variable measures the outcomes of the study, in this case, the level of preference or likability that individuals express toward others, influenced by their similarities or differences.
Method: To investigate the outlined hypothesis, a correlational approach will be used, allowing researchers to analyze the relationships between varying degrees of similarity and preference levels among participants.

Research Methods Pros and Cons

Descriptive Method:
- Pros: This method is valuable for providing rich, contextual information about a specific theory or behavior, allowing researchers to document phenomena in detail.
- Cons: However, descriptive studies are often limited in their generalizability, meaning the findings cannot always be confidently extended to broader populations. Additionally, these methods may lack robustness compared to more rigorous approaches.
Correlation Method:
- Pros: The correlation method is effective in identifying systematic relationships between variables, enabling researchers to explore potential associations and trends.
- Cons: Despite its strengths, this method cannot establish causation. It is crucial to remember that correlation does not imply causation, as other factors may influence the observed relationship.
Experimental Method:
- Pros: Experimental methods are robust because they allow researchers to draw causal
