Jade was asked to participate in an experiment. The experimenter read aloud to her a series of numbers that she was then asked to repeat back to him in the same order. As Jade continued to answer correctly, the lists became longer and longer until she finally could not get the numbers right. The experiment in which Jade was asked to participate involved the use of what memory test?

• A. Working memory test
• B. Echoic memory test
• C. The digit-span test
• D. Selective attention test

Answer: (C)

Verified step by step guidance

1. Understand the context of the experiment: Jade is asked to repeat a series of numbers in the same order, which tests her ability to hold and manipulate information temporarily.
2. Identify the type of memory being tested: The task requires Jade to use her short-term memory to recall the sequence of numbers, which is a key component of working memory.
3. Recognize the specific test used: The task described is known as the digit-span test, which measures the capacity of working memory by determining how many digits a person can remember in order.
4. Differentiate from other memory tests: Echoic memory involves auditory information storage for a brief period, while selective attention tests focus on filtering relevant information from distractions, neither of which directly apply to the task described.
5. Conclude that the experiment is a digit-span test, as it specifically assesses the number of items (digits) that can be held in working memory at one time.
