The Sternberg Paradigm Illustrates That When a Set of Letters

The Sternberg paradigm illustrates that when a set of letters held in short-term memory is tested with a recognition task, the time needed to respond to a probe item is

A) unrelated to the number of items in the memory set and is unrelated to whether the probe item was part of the original list.
B) unrelated to the number of items in the memory set but is affected by whether the probe item was part of the original list.
C) related by a linear function to the number of items in the memory set, the slope of which is the same regardless of whether the probe item was part of the original list.
D) related by a linear function to the number of items in the memory set, the slope of which is steeper when the probe item was not part of the original list.
