Research questions

Psychology tests questions about behavior and mental processes. Turn a broad curiosity into something observable, and distinguish evidence from a convincing personal story.

Psychology and Research question

Objective: Explain psychology and research question, distinguish their meanings, and apply them to a described case.

Psychology: Psychology scientifically studies behavior and mental processes. Research question: A research question identifies a relationship or phenomenon to investigate. Psychological research distinguishes a construct from the procedure used to measure it. Random sampling and random assignment serve different purposes. Experiments can support causal inference when design and execution address competing explanations; observational associations require more caution. Ethical protection, replication, and transparent reporting are part of scientific quality. One result is evidence to evaluate rather than automatic proof of a universal rule. Application: A researcher investigates how practice affects recall. This most directly illustrates psychology. A study asks whether sleep duration relates to attention. This most directly illustrates research question.

Step 1 — Read the observation: A researcher investigates how practice affects recall. Step 2 — Recall the relevant idea: Psychology scientifically studies behavior and mental processes. Step 3 — Connect the observation to the idea: The scenario is an illustration of psychology. Step 4 — Check the limit: This short scenario illustrates the concept; it does not establish every detail or exclude every other influence in a real situation.

Hypothesis and Operational definition

Objective: Explain hypothesis and operational definition, distinguish their meanings, and apply them to a described case.

Hypothesis: A hypothesis is a testable proposed explanation or prediction. Operational definition: An operational definition specifies how a variable is measured or manipulated. Psychological research distinguishes a construct from the procedure used to measure it. Random sampling and random assignment serve different purposes. Experiments can support causal inference when design and execution address competing explanations; observational associations require more caution. Ethical protection, replication, and transparent reporting are part of scientific quality. One result is evidence to evaluate rather than automatic proof of a universal rule. Application: A researcher predicts better recall after spaced practice. This most directly illustrates hypothesis. Attention is measured by errors on a stated task. This most directly illustrates operational definition.

Theory and Falsifiability

Objective: Explain theory and falsifiability, distinguish their meanings, and apply them to a described case.

Theory: A theory organizes evidence and mechanisms into an explanatory framework. Falsifiability: Falsifiability means evidence could count against a claim under specified tests. Psychological research distinguishes a construct from the procedure used to measure it. Random sampling and random assignment serve different purposes. Experiments can support causal inference when design and execution address competing explanations; observational associations require more caution. Ethical protection, replication, and transparent reporting are part of scientific quality. One result is evidence to evaluate rather than automatic proof of a universal rule. Application: A framework connects learning findings across several experiments. This most directly illustrates theory. A prediction states an outcome that would challenge it. This most directly illustrates falsifiability.
