Final answer:
Constructivism is the extension of symbolic interaction theory that suggests reality is what humans construct. It is used to explore the concept of deviance within society.
Step-by-step explanation:
Constructivism is an extension of symbolic interaction theory which proposes that reality is what humans cognitively construct it to be. We develop social constructs based on interactions with others, and those constructs that last over time are those that have meanings which are widely agreed-upon or generally accepted by most within the society.
This approach is often used to examine what's defined as deviant within a society. There is no absolute definition of deviance, and different societies have constructed different meanings for deviance, as well as associating different behaviors with deviance.
