Extracted text: 38. Which of the following best describes the capacity of short-term memory in humans? It seems to have unlimited capacity. It can hold 7 +or- 2 pieces of unrelated information. It can hold material for several hours even with no specific rehearsal. It can hold material for a maximum of a second or two if no processing is carried out. No valid studies of short-term memory have been conducted to accurately ascertain its capacity.
