    Study Notes

    Scientific Foundations of Psychology

    • Psychology is the scientific study of the mind and behavior.
    • Behavior encompasses anything an organism does.

    Contemporary Psychological Approaches

    • Behavioral: Learning; observable events are the focus. Key contributors include learning theorists like B.F. Skinner, and Ivan Pavlov.
    • Gestalt: Perception; the mind organizes visual perceptions as a whole. Key contributors included Max Wertheimer, Wolfgang Köhler, and Kurt Koffka.
    • Psychoanalytic/Psychodynamic: Unconscious thoughts and early childhood experiences shape personality. Key contributors include Sigmund Freud, and Erik Erikson.
    • Humanistic: Personal growth; humans have potential for self-improvement. Key contributors include Abraham Maslow and Carl Rogers.
    • Evolutionary: Natural selection favors behaviors that enhance reproductive success. Key contributors include Charles Darwin and David Buss.
    • Biological: Physiological bases of behaviour; examines bodily structures & biochemistry.
    • Cognitive: Thoughts, memory, language, problem-solving; examines mental processes.
    • Biopsychosocial: Combines biological, psychological, and social factors.
    • Sociocultural: Culture and environment on behaviour; examines cultural impacts.

    Research Methods

    • Basic Research: Advances knowledge without immediate practical applications.
    • Applied Research: Addresses practical problems.
    • Psychometrics: Assigns numerical values to behaviors, thoughts, and psychological phenomena.
    • Case Studies: In-depth study of one or a few individuals.
    • Naturalistic Observation: Observing behavior in natural settings.
    • Surveys: Collecting data through questionnaires.
    • Correlational Research: Examines relationships between variables.
    • Experiments: Manipulate independent variables to determine their effects on dependent variables. Experiments involve the manipulation of an independent variable, measuring a dependent variable, and exposing participants to various conditions. Participants' random assignment to conditions is essential to minimize confounding variables.
    • Cross-sectional Research: Compares different age groups at one time.
    • Longitudinal Research: Studies the same individuals over an extended period.

    The Experimental Method

    • Hypothesis: A testable prediction.
    • Independent Variable: Variable manipulated by the researcher.
    • Dependent Variable: Variable measured.
    • Operational Definitions: Clear, precise definitions of variables. Crucial for replication.
    • Replication: Repeating an experiment.
    • Extraneous Variable: Variables besides independent and dependent variables.
    • Confounding Variable: A type of extraneous variable that systematically varies with the independent variable, making it difficult to separate their effects.
    • Hawthorne Effect: Participants’ behavior changes due to being observed.
    • Placebo Effect: Participants’ response due to belief in treatment, not the treatment itself.
    • Double-Blind Procedure: Neither researchers nor participants know who received the treatment.
    • Random Assignment: Participants randomly assigned to groups to minimize bias.
    • Experimental Group: Receives treatment.
    • Control Group: Does not receive treatment, or may receive a placebo.

    Correlations

    • Correlation Coefficient (r): A number between -1 and +1 indicating the strength and direction of a relationship between two variables. Correlation does not equal causation.

    Descriptive Statistics

    • Mean: Average of scores. Calculated by summing all scores and dividing by the number of scores.
    • Median: Midpoint of scores.
    • Mode: Most frequently occurring score.
    • Range: Difference between highest and lowest scores.
    • Standard Deviation: Measure of data dispersion; indicates how spread out the data is. A low standard deviation indicates that the scores are clustered closely around the average, while a high standard deviation indicates that the scores are more spread out. A normal curve is a bell-shaped symmetrical curve that describes data, where most scores fall in the middle and fewer scores are at the extremes.

    Ethical Guidelines

    • Research conducted according to APA guidelines.
    • Informed consent given to participants before participation. Researchers must inform participants of the study's purpose, potential risks, and rights to withdraw.
    • Protection from harm, maintenance of confidentiality, debriefing, and voluntary participation. All participant experiences must be free of undue physical and or psychological harm.
    • Animal research adheres to IACUC (Institutional Animal Care and Use Committee) guidelines. Must use the fewest numbers of animals necessary for a valid research experiment, ensure humane treatment and appropriate care, and have caretakers perform regular health assessments.
