Quizplus · Accepted Answer

The correct answer is C) 7 plus or minus 2. This is based on a well-known theory by psychologist George A. Miller, who proposed that the number of objects an average human can hold in working memory (often referred to as short-term memory) is about seven, give or take two. This has been a foundational concept in cognitive psychology and has implications for various aspects of design, education, and everyday memory use.
