    Study Notes

    Research Methods

    • Dependent variable: The variable being measured or observed in an experiment
    • Holding all other variables constant: Ensuring that all variables, except the independent variable, remain constant to isolate the effect of the independent variable
    • Choosing a sample: Selecting a subset of the population to study, as it is often impossible to test a hypothesis on the entire population
    • Population vs. Sample: The population is the entire group of people being studied, while the sample is a subset of the population selected for study
    • Random sampling: Ensuring each member of the population is equally likely to be included in the sample
    • Representative sample: A sample that possesses the important characteristics of the population in the same proportions
    • Convenience sample: A sample recruited for convenience, which may not be representative of the population

    Operationalizing Variables

    • Turning abstract concepts into concrete variables: Measuring or manipulating abstract concepts to make them observable and measurable
    • Measuring self-esteem: Measuring self-esteem through exercises or surveys
    • Manipulating exercise: Manipulating exercise as an independent variable to observe its effect on self-esteem

    Reliability and Validity

    • Reliability: The ability of a measure to produce consistent results
    • Validity: The ability of a measure to assess the variable it is supposed to assess
    • Test-retest reliability: Ensuring a test produces similar results when taken multiple times
    • Internal consistency: Ensuring different items measuring the same variable produce consistent results

    Measurement and Variables

    • Variables: Phenomena that can vary, with continuous and categorical types
    • Measures: Assessing variables, ensuring reliability and validity in research

    Experimental Research

    • Scientific approach to psychology: Using empirical methodologies like observations and experimentation to gain knowledge
    • Logic of experimentation: Manipulating independent variables and observing dependent variables
    • Conditions: Different versions of the independent variable tested across experimental groups
    • Establishing causation: Showing how manipulating one variable affects another

    Ethics and Critical Thinking

    • Ethical considerations: Evaluating if the study treats participants humanely and justifies the incremental knowledge produced
    • Critical thinking: Carefully examining and analyzing information, evaluating evidence, and avoiding fallacies
    • Importance of critical thinking: Highlighting the significance of critical thinking in evaluating research

    Psychological Myths and Misinformation

    • Recognizing myths: Exploring the prevalence of psychological myths and misinformation
    • Earworms: Strengthening memories, evoking positive emotions, and being more common with songs people are happy with
