Psychology Chapter 1: Perspectives & Research Methods

Humanistic Perspective

• Emphasizes personal growth and self-actualization as central themes.

Sociocultural Perspective

• Investigates how cultural and social factors influence behavior.

Evolutionary Perspective

• Applies evolutionary theory to understand behavior and mental processes.

Goals of Psychological Research

• Aim to describe behaviors and mental processes accurately.
• Seek to explain underlying reasons for observed behaviors.
• Intend to predict future behaviors based on established patterns.
• Strive to control and positively influence behaviors through applied knowledge.

Hypotheses in Psychological Research

• Null Hypothesis (H0): Suggests no relationship exists between the studied variables.
• Alternative Hypothesis (H1): Indicates the presence of a relationship or effect between variables.

Methods of Psychological Research

• Descriptive Research: Involves case studies and surveys to characterize behaviors.
• Correlational Research: Analyzes statistical relationships between variables without implying causation.
• Experimental Research: Tests causation by manipulating variables in a controlled setting.
• Longitudinal Research: Observes the same subjects over an extended time period.
• Cross-Sectional Research: Compares different groups at a single point in time.
• Qualitative Research: Delves into complex phenomena through interviews and non-numerical data.

Ethical Issues in Psychological Research

• Informed Consent: Participants need complete information before consenting to research.
• Confidentiality: Protecting participant privacy is crucial.
• Debriefing: Participants receive full disclosure about the study after their involvement.
• Minimizing Harm: Priority is given to reducing potential risks to participants.
• Voluntary Participation: Participation must be entirely optional, allowing withdrawal at any time.
• Ethical Review Boards: Research proposals are evaluated to ensure compliance with ethical standards.

Review of Key Concepts in Early Psychology and Philosophy

• Observational Studies: Focus on behavior in natural contexts, yielding real-world insights but limited control over variables.
• Case Studies: Provide in-depth analysis of individuals or groups, offering detailed insights but lacking generalizability.
• Surveys: Utilize questionnaires or interviews for data collection, effective for large samples but prone to bias.
• Correlational Studies: Investigate relationships between variables, forming links rather than establishing causation.

Historical Figures and Movements

• Thomas Aquinas: Integrated Christian theology with Aristotelian philosophy; argued that reason and faith coexist.
• Renaissance (14th to 17th Centuries): Renewed interest in human potential, driving humanism and studies in ethics and human behavior.
• Humanism: Shifted focus towards secular and individualistic perspectives, emphasizing the human mind's potential.
• Leonardo da Vinci: Advanced understanding of human anatomy, influencing psychological exploration.

Emergence of Modern Psychology (17th and 18th Centuries)

• Rationalism vs. Empiricism: Debated philosophical approaches shaping psychology.
• Rene Descartes: Introduced the concept of dualism, asserting the separation of mind and body; noted for "Cogito, ergo sum."
• John Locke: Proposed knowledge originates from sensory experience; likened the mind at birth to a blank slate.
• David Hume: Expanded on empiricism, asserting human understanding is derived from sensory impressions, not pure reasoning.

Early Biological Foundations of Psychology

• Hermann von Helmholtz: Pioneered studies in sensory perception and reaction times, linking physiological studies with psychological research.

19th Century: The Birth of Psychology as a Science

• Wilhelm Wundt: Founded the first psychology laboratory in Leipzig in 1879, marking psychology's establishment as an empirical science.
• Jean Piaget: His research laid the groundwork for developmental psychology, focusing on cognitive development in children.

Institutionalization of Psychology

• Formation of professional organizations like the American Psychological Association (APA) solidified psychology as an academic discipline.
• Growth in publication and research established psychology's robustness and diversity.

Cognitive Revolution

• Transition from behaviorism to internal mental processes during the 1950s and 60s.
• Key Figures: George A. Miller emphasized cognitive limits; Ulric Neisser is known as the "father of cognitive psychology"; Aaron Beck and Albert Ellis introduced Cognitive Behavioral Therapy (CBT).
• Key Concepts: Focus on information processing, mental schemas, and cognitive functions like memory and perception.

Humanistic Psychology

• Arising in reaction to behaviorism and psychoanalysis, focusing on personal growth and free will.
• Key Figures: Carl Rogers promoted client-centered therapy emphasizing empathy; Abraham Maslow developed the Hierarchy of Needs centering on self-actualization.
• Key Concepts: Highlighted human potential, personal growth, and the importance of subjective experience.
