Study Notes

Features of Science

Systematic empiricism is the foundation of science, where observation leads to learning, and scientists meticulously plan, implement, record, and analyze observations.
Empirical questions are questions about the reality of the world, which can be answered through systematic observation.
Scientists disseminate their research findings through publications, making science a dynamic process that fosters collaboration and self-correction.

Science Versus Pseudoscience

Pseudoscience presents claims that appear scientific but lack scientific rigor.
Examples of pseudoscience include cryptozoology, pseudoscientific psychotherapies, homeopathy and pyramidology.

Clinical Psychology and Research

Clinical psychology, focused on diagnosing and treating psychological issues, relies heavily on the scientific discipline of psychology.
Research plays a crucial role in understanding psychological problems and evaluating the efficacy of treatments.

Chapter 2: Variables

A variable is a quality or quantity that can change across people or situations.
Quantitative variables are measurable quantities represented by numbers, like height or depression levels.
Categorical variables represent qualities, such as chosen major, and are assigned category labels.

Sampling and Measurements

Population refers to the larger group of individuals researchers are interested in studying.
Simple random sampling ensures that all members of the population have an equal chance of being selected for the study.
Convenience sampling selects participants based on accessibility.
Operational definitions specify how variables will be measured in a study.

Statistical Relationships Between Variables

A statistical relationship exists between two variables when the average score on one variable changes systematically across different levels of the other variable.
Two common forms of statistical relationships are differences between groups and correlations between quantitative variables.
The APA Ethics Code outlines ethical guidelines for researchers in psychology.
Informed consent is obtained from participants, assuring them of the study's nature and potential risks.
Deception in research might involve misleading participants about the study's purpose or using misleading equipment.
Debriefing informs participants about the study's purpose and any deception used, ensuring they understand their participation.
Scholarly integrity is vital, prohibiting data fabrication or plagiarism.

Chapter 4: Phenomena and Theories

Phenomena are observed results consistently found in systematic empirical research.
Examples of psychological phenomena include blindsight, the bystander effect, the fundamental attribution error, the McGurk effect, the other-race effect, the placebo effect, the mere exposure effect, the serial position effect, and spontaneous recovery.
Replication is the process of repeating a study to confirm its results.
A theory provides a comprehensive explanation or interpretation of one or more phenomena.
A perspective is a broad approach to explaining and interpreting phenomena.
A model offers a specific and precise explanation of a single phenomenon.
A hypothesis is a preliminary explanation relying on a few key concepts.
A theoretical framework provides a context for understanding a phenomenon, encompassing breadth or specificity.

The Purpose of Theories

Theories offer accurate explanations and interpretations of observed phenomena, helping to organize information, facilitate predictions, and generate new research.

Constructs, Conceptual Definitions, and Operational Definitions

Constructs are psychological concepts that cannot be directly observed, often representing tendencies or dispositions.
Conceptual definitions describe the concept's components, behavior, and internal processes, illustrating how it relates to other variables.
Operational definitions specify how a construct will be measured in a study.

Levels of Measurement

Nominal level assigns categorical labels, signifying differences but not order or magnitude.
Ordinal level assigns scores based on rank order, indicating relative position but not equal intervals.
Interval level uses numerical scales with equal intervals, allowing for comparisons of differences.
Ratio level has a true zero point, representing the complete absence of the variable, allowing for comparisons of ratios.

Reliability and Validity of Measurements

Reliability refers to the consistency of a measure, indicating how consistently a measure produces similar results under consistent conditions.
Test-retest reliability evaluates the consistency of a measure over time.
A valid measure accurately measures the intended construct.
Content validity assesses whether a measure adequately reflects the construct's full range.
Criterion validity examines the correlation between a measure and a criterion, an external variable expected to be related to the construct.
Construct validity explores the degree to which a measure relates to other measures as expected based on the construct's theoretical underpinnings.
