What is the major difference between the short-term memory and the working memory? 96. (part 29, easy) 105-Final
A. The working memory requires the ability to manipulate/transform the information and use it in high-level behaviors.
B. The working memory is shorter than the short-term memory
C. The working memory requires the ability to transform the short-term memory into a long-term memory.
D. The short-term memory exists in all animals but the working memory only exists in humans.
