Psychology Study Guide

Methods

  • Applied vs. Basic Research:

    • Basic Research: Explores fundamental principles and theories to advance scientific knowledge. Example: Investigating the neural mechanisms of memory.
    • Applied Research: Seeks to solve specific, practical problems using existing knowledge. Example: Evaluating the effectiveness of a new therapy for depression.
  • Variables:

    • Independent Variable (IV): The variable manipulated by the researcher.
    • Dependent Variable (DV): The variable measured to see if it is affected by the independent variable.
  • Validity: The extent to which a test or experiment measures what it is supposed to measure. High validity means the results accurately reflect the phenomenon being studied.

  • Reliability: The consistency of a measure or experiment. High reliability means that the same results are obtained if the experiment is repeated.

  • Sampling:

    • Sample: A subset of the population selected for study.
    • Target Population: The entire group of individuals to which researchers want to generalize their findings.
    • Stratified Sample: A sampling technique where the population is divided into subgroups (strata), and samples are taken proportionally from each stratum.
  • Confounding Variable: A variable that influences both the independent and dependent variables, creating a spurious association.

  • **Experimental Designs:

    • Repeated Measures: Each participant performs in every condition of the experiment.
    • Order Effect: The order of presenting treatments affects the dependent variable (e.g., practice effect, fatigue effect).
    • Random Assignment: Participants are assigned to different experimental groups randomly to ensure that groups are equivalent at the start of the experiment.
    • Control: Steps taken to minimize the effects of extraneous variables.
    • Group Matching: Participants are grouped based on similar characteristics (e.g., age, gender) to ensure equal representation in each condition.
    • Single-Blind Study: Participants are unaware of which treatment they are receiving.
    • Double-Blind Study: Both participants and researchers are unaware of which treatment is being administered.
  • **Bias:

    • Hawthorne Effect: Participants' behavior changes because they know they are being observed.
    • Placebo Effect: A beneficial effect produced by a placebo drug or treatment, which cannot be attributed to the properties of the placebo itself, and must therefore be due to the patient's belief in that treatment.
  • Correlational Studies:

    • Positive Correlation: Variables increase or decrease together.
    • Negative Correlation: As one variable increases, the other decreases.
  • Research Methods:

    • Correlational Study: Examines the relationship between two or more variables without manipulating them.
    • Survey: Gathers data from a sample through questionnaires or interviews.
    • Naturalistic Observation: Observing and recording behavior in a natural setting.
    • Case Study: In-depth investigation of a single person, group, or event.
