Backward Digit Span Task
The backward digit span task is a highly structured laboratory procedure used as a behavioral measure of working memory capacity. In this task, a researcher reads a sequence of digits to a participant, who must then repeat the sequence in reverse order. The length of the longest correctly recalled sequence serves as the operational definition of their working memory capacity.

In cognitive psychology, how is 'working memory capacity' primarily defined?
In cognitive psychology, how is 'working memory capacity' defined?
A researcher wants to measure a participant's ability to simultaneously hold and manipulate information in mind. She designs a task in which participants simply listen to a list of single digits and then immediately repeat them back in the same order, with no other cognitive demands during the task. This task is a valid measure of that ability because it assesses how much information a person can keep in mind at one time.

Dr. Chen is designing a research study to investigate how acute stress affects working memory capacity (WMC). To operationalize WMC, she must select a measurement procedure that captures its conceptual definition. She considers two potential tasks:
Task 1: Participants hear a list of unrelated words (e.g., 'apple, tree, book') and must immediately repeat them back in the exact order heard. Task 2: Participants read a sentence (e.g., 'The dog chased the cat up the tree.'), decide if it makes logical sense, and then see an unrelated word to remember. After several sentences, they must recall all the unrelated words in order.
