Knowra Psychological research Psychological research Psychological research is the systematic study of mental processes and behavior using methods such as experiments, observation, surveys, and statistical analysis.
Experimental design : The planning of a study to test hypotheses while controlling sources of bias and uncertainty. It determines how psychological studies compare conditions and test causal claims.
Research question : A focused question that specifies what an investigation aims to learn. It guides the choice of design, measures, and analyses.
Clinical psychology : The field concerned with assessing and treating mental disorders and psychological difficulties. Clinical practice draws on research about diagnosis, treatment, and outcomes.
Replication crisis : A widespread concern that many published research findings fail to reproduce reliably. Psychology became a prominent focus of efforts to test published results again.
Qualitative research : Research that analyzes non-numerical material to understand meanings, experiences, or social processes. It can investigate lived experience that standardized measures may miss.
Randomized controlled trial : An experiment that assigns participants randomly to intervention and comparison groups. Random assignment can help isolate an intervention’s effects on behavior or mental health.
Hypothesis : A testable proposal about a relationship, difference, or process. Psychological studies often derive predictions from hypotheses before gathering data.
Evidence-based practice : Decision-making that integrates research evidence with professional expertise and client values. It translates psychological findings into choices about care.
Open science : Practices that make research methods, materials, data, or results more transparent and accessible. Open practices address concerns about hidden analyses and irreproducible findings.
Quantitative research : Research that represents observations numerically and analyzes patterns with mathematical or statistical methods. It emphasizes measurement and numerical comparisons within psychological inquiry.
