Constructs

Operational Definition

• The descriptions of constructs that we settle on, and that allow us to measure them in the real world, are called operational definitions.
• Example - the percentage of faces correctly recognised in the BBC face memory test is the operational definition of a good memory.
• So the operational definition of a construct is defined by the way chosen from several other ways, to measure the construct.
• Age is also a construct since it can be defined in several ways - no. of years a person has lived, maturity of a person or wisdom.
