First, preemptive and preventive uses of force are often justified by claiming either that there is substantial risk of a future attack or that it is difficult to ascertain how dangerous the target is.
Short-Term Memory: Up to 7 Items, But Highly Volatile. Many psychology experiments have shown that our short-term memory can hold only a limited number of separate items. The average is about 7 items, plus or minus 2, depending on the individual. You can easily confirm this by reading someone a series of words that have no connection with one another, then asking this person to repeat them.
Participants are presented. with a series of stimuli and after a period of time are asked to recall what was just presented to. them. From previous research such as the Memory Span experiment is has been suggested that. the capacity to hold information reaches its limits at seven plus or minus two items. In order to further the previous findings it has been suggested to modify the memory span. experiment to explore the effects different types of items have on memory and the magic number. of seven. The current study explores digits and words as if the mind processes these in the same. or different ways.
