I've previously referenced the concept of "cognitive efficiency" in the context of the CHC Theory of Intelligence (also check here). Briefly, this construct references the interaction of cognitive processing speed (Gs) and working memory (Gsm-MW).Today I read what I think is a nice definition for "efficiency" in the context of human cognitive abilities. Charles Perfetti (2007), in an a recent article ("Reading Ability: Lexical Quality to Comprehension") published in the Scientific Studies of Reading (11-4; 357-383), stated:
- "Efficiency is not the same as speed. Efficiency is a ratio of outcome to effort, with time as a proxy for effort."(p. 359)
