    Study Notes

    Research Methods and Design

    • Correlation does not equal causation. A correlation between variables doesn't prove a cause-and-effect relationship. Other factors may be influencing both variables.
    • Reliability refers to consistency. A reliable measure produces similar results consistently across multiple trials or observers.
    • Validity refers to accuracy. A valid measure truly reflects what it intends to measure.
    • Reliability types include test-retest, inter-rater, and intra-rater reliability.
    • Validity types include construct, internal, and external validity.
    • Observational studies do not involve manipulation of variables.

    Research Designs

    • Experimental studies manipulate an independent variable to observe its effect on a dependent variable. Randomized controlled trials (RCTs) are a type of experimental study.
    • Quasi-experimental studies are like RCTs but lack random assignment of participants to groups.
    • Pre-experimental studies have limitations, such as lacking a control group.
    • Qualitative research approaches focus on understanding experiences and perspectives, rather than numerical data. Examples include case studies and ethnographies.
    • Sampling methods for research include target population and accessible population, and potential bias in sampling.
    • Hypothesis testing involves evaluating evidence to determine whether to reject or fail to reject a null hypothesis.

    Research Ethics

    • The Tri-Council Policy Statement (TCPS 2) provides ethical guidelines for human research in Canada, including respect for persons, concern for welfare, and justice.
    • Informed consent requires providing clear and comprehensive information to participants about the study, including its purpose, procedures, risks, and benefits.
    • Confidentiality and privacy are crucial in research.

    Philosophical Foundations of Research

    • Epistemology studies knowledge and justified belief.
    • Ontology studies being and the nature of reality.
    • Research paradigms, such as positivism and interpretivism, reflect differing assumptions about the nature of reality and knowledge.

    Visual Perception and Cognition

    • Top-down and bottom-up processing are two interacting processes in visual perception. Bottom-up processing analyzes basic sensory information, while top-down processing uses prior knowledge and experiences to understand stimuli.
    • Cognitive biases may influence how we interpret information and make decisions.

    Critical Evaluation of Information

    • Appeals to authority must be considered with caution. Expert opinions can be valuable but are not sufficient evidence alone.
    • Secondary sources interpret primary sources. Be aware of potential biases in secondary sources.
    • Peer review is a quality control mechanism in academic publishing.

    Key Terms and Concepts

    • Confounding variables can influence the relationship between variables.
    • Double-blind studies minimize bias in research.
    • Independent variables are manipulated to observe effects on dependent variables.
    • Dependent variables are measured in response to the independent variable.

    Additional concepts

    • Knowledge translation involves moving research findings into practice.
    • Meta-analysis combines results from multiple studies.
    • Member checking ensures that interpretations accurately reflect participant experiences.
    • Qualitative research involves collecting data through methods such as interviews and observations, yielding non-numerical data.
    • Quantitative research focuses on numerical data analysis.
    • Systematic review is a comprehensive assessment of existing research.
    • Triangulation utilizes multiple data sources to enhance research credibility.
