As the brand behind so much of the popular technology we use today, Apple's logo is one of the most recognisable in the world. Or is it? Researchers at the University of California asked 85 people to draw it from memory, and then scored their attempts for accuracy. Only one person got it right. When asked to pick the correct logo out of a line-up of 12 similar designs, fewer than half the participants chose the correct one. The surprising results were said to support the theory that over-exposure to a logo does not necessarily mean our memories of it will be accurate. Quite the opposite might be true, in fact. How would you get on?
