When analyzing the internal structure of Cacioppo and Petty's (1982) study, a researcher would classify occupation (professor vs. factory worker) as a _____ variable—a pre-existing participant characteristic that sorts people into groups without any experimental manipulation—and would conclude that this feature is precisely why the design cannot support a causal claim about occupation's effect on need for cognition.
