Psychology Critical Thinking Quiz

Cognitive Biases

• Hindsight Bias: The tendency to see events as having been predictable after they have already occurred, often leading to an overestimation of one's ability to predict outcomes.
• Confirmation Bias: The inclination to search for, interpret, and remember information that confirms preexisting beliefs while ignoring contradictory evidence.
• Overconfidence: A cognitive bias characterized by an individual's subjective confidence in their judgments being reliably greater than their objective accuracy.

Psychology Concepts

• Critical Thinking: The objective analysis and evaluation of an issue in order to form a judgment, essential for problem-solving and decision-making.
• Peer Reviewers: Experts who evaluate scientific papers before publication to ensure validity, quality, and significance of research.

Research Fundamentals

• Theory: A well-substantiated explanation of an aspect of the natural world, formulated through repeated testing and observation.
• Hypothesis: A testable prediction about the relationship between variables.
• Falsifiable: The capacity of a statement or hypothesis to be proven false through evidence.
• Operational Definition: A clear, specific definition of a variable that outlines how it will be measured or manipulated in a study.
• Replication: The process of repeating a study to see if the original findings can be consistently reproduced.

Research Methods

• Case Study: An in-depth examination of a single individual or group, often used in exploratory research.
• Meta-Analysis: A statistical analysis that combines results from multiple studies to identify patterns and draw conclusions.
• Naturalistic Observation: Observing behavior in its natural environment without interference to understand real-world dynamics.
• Survey: A data collection method that involves asking participants questions, often used to gather quantitative data.

Biases in Research

• Social Desirability Bias: The tendency for participants to respond in a manner that will be viewed favorably by others, affecting the accuracy of self-reports.
• Self-Report Bias: Limitations inherent in individuals' ability to report their own thoughts, feelings, and behaviors accurately.
• Experimenter Bias: When researchers unintentionally influence their findings due to their expectations or preferences.

Sampling Techniques

• Population: The entire group of individuals or instances about which we seek to draw conclusions.
• Sample: A subset of the population selected for participation in a study.
• Sampling Bias: A flaw in sampling method that leads to a non-representative sample, affecting the validity of the study.
• WEIRD: Acronym for Western, Educated, Industrialized, Rich, and Democratic; often criticized for being overrepresented in psychology research.
• Random Sample: A method in which every member of the population has an equal chance of being selected.
• Stratified Random Sample: A sample that divides the population into subgroups and selects samples from each, ensuring accurate representation.
• Convenience Sampling: A non-random sampling method that selects participants based on ease of access rather than random selection.
• Opportunity Sampling: Similar to convenience sampling but focuses specifically on selecting participants who are readily available.
• Representative Sample: A sample that closely mirrors the characteristics of the broader population.

Experimental Design

• Experimental Methodology: A research strategy that involves manipulating variables to determine cause-and-effect relationships.
• Non-Experimental Methodology: Research approaches that do not involve manipulation of variables, such as observational studies or surveys.
• Correlation: A statistical measure that describes the extent to which two variables change together.
• Correlation Coefficient: A numerical value between -1 and 1 that indicates the strength and direction of a correlation.
• Variable: Any factor that can be changed or controlled in a study, affecting the outcome.
• Scatterplot: A graphical representation of the relationship between two numerical variables, used to illustrate correlations.
• Illusory Correlation: The perception of a relationship between two variables when none exists, often due to cognitive biases.
• Directionality Problem: A challenge in correlational research that prevents determining which variable influences the other.
• Third Variable Problem: A situation where an unidentified variable affects both of the variables being studied, confounding the results.
• Regression Toward the Mean: The phenomenon where extreme values on one measurement tend to be closer to the average on subsequent measurements.

Experiment Components

• Experiment: A research design where variables are manipulated to observe effects on other variables.
• Experimental Group: The group in an experiment that receives the treatment or intervention.
• Control Group: A baseline group that does not receive the experimental treatment, used for comparison.
• Independent Variable(s): The variable(s) manipulated in an experiment to observe effects on the dependent variable(s).
• Dependent Variable(s): The outcome variable(s) measured to assess the impact of the independent variable(s).
• Random Assignment: The process of randomly allocating participants to experimental and control groups to eliminate bias.
• Single-Blind Procedure: An experimental design where participants do not know if they are in the experimental or control group to prevent expectations from influencing results.
• Double-Blind Procedure: A research design in which neither participants nor experimenters know who is receiving a treatment, minimizing bias.
• Placebo: An inactive substance or treatment administered to control groups to account for the placebo effect.
• Placebo Effect: Improvement in condition resulting from expected effects rather than the actual treatment.
• Confounding Variable: An external variable that is not controlled and may impact the dependent variable, leading to erroneous conclusions.
