Cognitive Psychology Experimentation Quiz

Random assignment ensures each participant has an equal chance of being in any condition.

Control groups establish a baseline against which the effects of other conditions are compared.

Debriefing informs participants about the study's aims, procedures, and addresses any concerns or misconceptions.

Demand characteristics are cues that may lead participants to infer the study's aims and adjust behavior accordingly.

Internal validity concerns whether changes in the dependent variable are due to the independent variable rather than other factors.

Cross-sectional designs assess different groups at a single point in time and cannot track changes over time.

ANOVA assesses if there are differences in means across groups.

Independent variables are manipulated to observe their effects on dependent variables.

Random assignment minimizes bias by equally distributing participants across conditions.

The hypotheses of the researcher are not a confounding variable but guide the study's direction.

Experimental research aims to understand and explain cognitive processes and behaviors.

Lab experiments may suffer from demand characteristics, where participants alter behavior due to perceived expectations of the study.

Double-blind experiments prevent bias by keeping both participants and researchers unaware of group assignments.

Reliability concerns the consistency of results or measurements over repeated trials or time.

Operational definitions specify how variables are measured or manipulated in an experiment.

Within-subjects designs involve participants experiencing all levels of the independent variable.

Deceiving participants about the true nature of the study raises ethical concerns.

Counterbalancing ensures that the order in which conditions are presented does not bias the results.
