Closely related to working memory, which refers to our ability to hold on to information we"re currently thinking about, attending to, or processing actively. Memory loss from short-term memory: decay vs. Decay: fading of information from memory over time. Interference: loss of information from memory because of competition from additional information. Retroactive interference: interference with retention of old information due to acquisition of new information. Proactive interference: interference with acquisition of new information due to previous learning of information. The capacity of short-term memory: the magic number: The digit span of most adults is between 5 and 9 digits, with an average of 7 digits.
