    Study Notes

    Deductive vs. Inductive Reasoning

    • Deductive reasoning begins with a generalization and tests it against real-world observations.
    • Inductive reasoning uses observations to form broad generalizations.
    • Inductive reasoning conclusions may or may not be correct, even with accurate observations.
    • Scientists use inductive reasoning to create theories and deductive reasoning to test them.

    Theories and Hypotheses

    • Theories are well-developed explanations for observed phenomena.
    • Theories are complex and tested by smaller, specific hypotheses.
    • Hypotheses are testable predictions about how the world will act if a theory is correct.
    • Hypotheses bridge the gap between ideas and the real world.
    • Falsifiable hypotheses can be proven incorrect, which is crucial for scientific advancements.

    Case Studies and Experimental Research

    • Case studies are heavily inductive, gathering large amounts of data for pattern recognition.
    • Experimental research emphasizes deductive reasoning.
    • The James-Lange theory of emotion suggests that physiological arousal leads to emotional experience.

    Peer Review in Research

    • Peer review ensures quality control in psychological research.
    • Peer reviewers evaluate the research, its value, and clarity.
    • They ensure scientific integrity, prevent research duplication, and improve research quality.
    • Peer reviewers suggest revisions or rejection for publication.
    • Replication of research findings strengthens their validity.

    The "Replication Crisis"

    • Concerns exist about studies failing replication.
    • Even renowned scientists have retracted published work due to replication challenges.
    • This has led to collaborations and more open research practices.

    Vaccine-Autism Myth

    • Debunked research claimed a link between vaccines and autism.
    • This led to anti-vaccination movements.
    • Large-scale research has shown no connection, and original studies were retracted.
    • Mistrust in vaccinations has serious consequences, such as outbreaks of preventable diseases.

    Validity of Standardized Tests

    • Standardized tests like the SAT and ACT are designed to measure college aptitude.
    • Research suggests these tests have predictive validity for college GPA.
    • However, some argue that these tests are biased.
    • Their predictive validity has been questioned and may be exaggerated.
    • Some institutions are de-emphasizing standardized tests in admissions.

    Ethics in Research

    • Research involving human subjects is ethically regulated.
    • Informed consent and debriefing are crucial processes.
    • Research involving animals is also regulated.
    • Ethical research respects human dignity and safety.

    Pioneers in Psychology

    • Francis Cecil Sumner was one of the founders of Howard University’s department of psychology, often referred to as the “Father of Black Psychology”
    • Inez Beverly Prosser was the first African American woman to earn a PhD in psychology in 1920. Her research focused on the impact of segregation on education, which ultimately influenced the landmark Brown v. Board of Education Supreme Court ruling.
    • Margaret Floy Washburn was the first woman to earn a doctorate degree in psychology.
    • Horatio Piñero established some of the first experimental psychology labs in South America in Buenos Aires, Argentina.
    • Gunamudian David Boaz and Narendra Nath Sen Gupta established the first independent psychology departments in India at the University of Madras and the University of Calcutta.

    Psychology in the United States

    • While the American Psychological Association (APA) began in 1892 with only White male members, Mary Whiton Calkins became the first female president in 1905.
    • By 1946, nearly one-quarter of American psychologists were female.
    • Historically Black colleges and universities played a crucial role in increasing the number of Black Americans who became psychologists.

    Research Methods: Surveys

    • Surveys are a common method for collecting data.
    • Surveys can be used to gather information on a variety of topics, such as attitudes, behaviors, and beliefs.
    • Researchers can use surveys to understand public opinions and social trends.
    • A study by Jenkins et al. (2012) used surveys to investigate the backlash against the US Arab-American community following the September 11, 2001, terrorist attacks. Their findings suggested that participants exhibited subtle forms of prejudice against Arab-Americans, despite their assertions that they did not.

    Research Methods: Archival Research

    • Archival research involves analyzing existing records or data sets, such as academic transcripts or historical documents.
    • This approach allows researchers to explore patterns and relationships without directly interacting with participants.
    • It is cost-effective and efficient since data collection is already done.
    • One limitation is that researchers have no control over the original data collection, limiting the types of research questions that can be addressed.

    Research Methods: Longitudinal and Cross-Sectional Research

    • Longitudinal research involves studying the same group of participants over an extended period of time to observe changes and trends.
    • Cross-sectional research compares multiple segments of the population at the same time, providing snapshots of differences across groups.

    Experiment Design: Placebo Effect and Control Groups

    • The placebo effect refers to participants experiencing positive effects simply due to the expectation of a treatment, even if it’s an inactive substance like a sugar pill.
    • Control groups are essential for evaluating the effectiveness of a treatment. They receive either no treatment or a placebo, allowing researchers to isolate the impact of the actual treatment.

    Independent and Dependent Variables

    • The independent variable is the factor that is manipulated or controlled by the researcher.
    • The dependent variable is the outcome that is measured to determine the effect of changes in the independent variable.

    Reliability and Validity

    • Reliability in research refers to a tool’s consistency in producing the same results when repeated.
    • Validity, on the other hand, focuses on a tool’s accuracy in measuring what it is intended to measure.
    • Researchers strive to use instruments that are both reliable and valid.

    Why Research is Important

    • Psychology, as a scientific field strives to understand behavior from various perspectives, including cognitive and physiological.
    • Research highlights the importance of critical thinking and skepticism when evaluating information.

    Research: Facts and Opinions

    • Research delves into the process of understanding truth and reliable information.
    • It scrutinizes the concept of objective information and why it's crucial to trust certain information.

    The Process of Scientific Research

    • The process of scientific research is continuous and cyclical, similar to the concept of a ring, resembling Gollum's ring from Lord of the Rings.

    Inductive Versus Deductive Reasoning

    • Deductive reasoning starts with a theory and generates a hypothesis to be tested through observations.
    • Inductive reasoning begins with observations and leads to patterns and eventual theories.
    • The scientific method aims to confirm or reject a hypothesis based on observations, thereby either supporting or rejecting the initial theory.

    Approaches to Research

    • The goal of Psychology is to: describe, explain, predict and change behavior.
    • Approaches to research vary depending on the subject of research and the specific questions being investigated.

    Case Studies/Clinical Studies

    • This approach involves an in-depth study of a single individual or a specific group, often with rare characteristics or specific traits.
    • While providing rich data about the subject, case studies lack generalizability, meaning their findings cannot be applied to a wider population.

    Henry Molaison (H.M.)

    • H.M. underwent surgery to address seizures but suffered memory loss as a result.
    • He serves as a case study example for clinical research and understanding memory.

    Naturalistic Observation

    • This approach allows studying behavior in its natural environment without intervention from the observer.
    • Challenges exist with observer bias, which can be addressed through inter-rater reliability to ensure consistent measurements.

    Survey Research

    • This approach utilizes questionnaires, interviews, or tests to gather information about behaviors from a large group of people quickly.
    • While offering strong generalizability, surveys may not always elicit honest responses, as participants might provide answers they believe the researcher wants.

    Archival Research

    • This method examines existing documented information, searching for patterns or relationships without direct participant interaction.
    • Advantages include low cost and no need for participant contact.
    • Limitations include being restricted to available information and not being able to manipulate variables or data.

    Longitudinal and Cross-Sectional Research

    • Longitudinal research collects data repeatedly over time, examining change over an extended period.
    • Cross-sectional research involves comparing different segments of the population simultaneously at a single point in time.

    Analyzing Findings: Correlational Research

    • Correlation research determines the degree of relationship between two variables, exploring how they change together.
    • There are positive, negative, and zero correlations, but correlation does not necessarily indicate causation.

    Analyzing Findings: Illusory Correlations

    • Illusory correlations occur when people perceive a relationship between two things when no such relationship actually exists.
    • Confirmation bias fuels this phenomenon as people tend to seek information confirming their existing beliefs while ignoring conflicting evidence.

    Analyzing Findings: Causality, Experiments and Data

    • Experimental hypotheses aim to test the relationship between variables through experiment manipulation.
    • Experiments involve controlling the independent variable and observing its effects on the dependent variable.

    Analyzing Findings: Designing an Experiment

    • Experiments often include two groups: experimental and control.
    • The experimental group receives the treatment or manipulation of the independent variable, while the control group does not.
    • Single-blind and double-blind studies are used to reduce experimenter bias, preventing both the researcher and participant from knowing which group receives the treatment.

    Analyzing Findings: Selecting and Assigning Participants

    • Participants are the subjects of psychological research, and random sampling aims to assign them to groups (control or experimental) fairly.
    • This ensures each individual has an equal chance of being selected for either group.

    Analyzing Findings: Interpreting and Reporting Research

    • Statistical analysis helps interpret experimental data, drawing conclusions about the findings.
    • Reporting research must consider the target audience and present data in a clear and concise manner.
    • The research should be replicable, meaning others can repeat the experiment with the same conditions and yield similar results.

    Analyzing Findings: Reliability and Validity

    • Reliability refers to the consistency of research findings. A reliable experiment consistently produces similar results, regardless of the researchers involved.
    • Validity addresses the accuracy of the measurements, ensuring the research is measuring what it intends to measure.

    Ethics

    • Ethical guidelines govern research practices to maintain the integrity of experiments and ensure participant safety.
    • The American Psychological Association (APA) provides specific guidelines for research involving humans, focusing on confidentiality, informed consent, and deception.
    • An Institutional Review Board (IRB) oversees research involving human participants.

    Ethics: Research with Animals

    • Ethical guidelines also apply to research involving animals.
    • An Institutional Animal Care and Use Committee (IACUC) ensures the ethical treatment of animals in research.
