An abstract or theoretical characterization specifies the meaning of a construct or variable in theoretical terms. It describes what the construct represents and its relationship to other constructs. For example, intelligence might be described as the general cognitive ability encompassing reasoning, problem-solving, and learning. This characterization contrasts with how the construct is measured or manipulated in research.
This type of characterization is fundamental to theoretical development and scientific communication. It provides a shared understanding of the phenomena under investigation, guiding research design, interpretation of findings, and theory building. Historically, ambiguity regarding these characterizations has hindered progress in various subfields of the discipline, leading to inconsistent findings and debates about the validity of research.
