Study Notes

Psychology's Roots

Critical thinking involves questioning assumptions, evaluating sources, considering hidden values, analyzing evidence, and assessing conclusions.
Structuralism, an early school of thought, focused on the structure of the human mind, pioneered by Wundt.
Functionalism, another early school, explored how the mind functions, influenced by Darwin's work.
Behaviorism emphasizes objective observation of behavior, excluding mental processes, a viewpoint agreed upon by modern psychologists regarding objective observation but not the exclusion of mental processes.
Humanistic psychology emphasizes human potential for growth.
Cognitive psychology studies mental processes such as perception, learning, memory, thinking, communication, and problem-solving.
Cognitive neuroscience explores the link between brain activity and mental processes.

Research Methods

Biopsychosocial approach incorporates biological(natural), psychological, and social-cultural viewpoints to understand behavior.
Nature-nurture issue examines the interplay between genes and experience in shaping traits and behaviors; traits develop through the interaction of genes and environment.
Dual processing describes the mind's simultaneous conscious and unconscious information processing.
A theory is an explanation using principles to organize observations and predict behaviors/events.
A hypothesis is a testable prediction often based on a theory.
Operational definition specifies exact procedures in a research study (e.g., defining intelligence through an intelligence test).
Replication involves repeating a study with different participants in different situations to validate results.
Case study analyzes an individual or group in depth to uncover universal principles.
Naturalistic observation studies behaviors in natural settings without manipulation.
Surveys collect self-reported attitudes/behaviors from a representative sample.
A population refers to all members of a particular group.
A random sample fairly represents the population.
Correlation measures the relationship between two variables.
A correlation coefficient measures the strength and direction of a correlation (-1 to +1; 0=no relationship).

Experimental Methods

Placebo effect refers to a response to a treatment that is not the actual treatment .
Experimental group receives the independent variable (treatment).
Control group does not receive the independent variable.
Double-blind procedure ensures both participants and researchers are unaware of who receives treatment or placebo to prevent bias,
Independent variable is the manipulated variable in an experiment.
Dependent variable is the measured variable in an experiment.
A confounding variable influences results but isn't the focus of the study.
Informed consent ensures participants understand the study before participation.
Debriefing explains the study's purpose after the session.
