Digit-span tasks can be given forwards or backwards, meaning that once the sequence is presented, the participant is asked to either recall the sequence in normal or reverse order. [8] Digit-span tasks are the most commonly used test for memory span, partially because performance on a digit-span task cannot be affected by factors such as ...
Cubes and a target pattern of the WAIS-R's "Block Design" test. The WAIS-R, a revised form of the WAIS, was released in 1981 and consisted of six verbal and five performance subtests. The verbal tests were: Information, Comprehension, Arithmetic, Digit Span, Similarities, and Vocabulary.
This number is known as the Corsi Span, and average is about 5–6 for normal human subjects. An fMRI study involving subjects undergoing this test revealed that while the sequence length increases, general brain activity remains the same. So while humans may show encoding difficulty, this is not related to overall brain activation.
Tzeng (1973) reported an instance where the recency effect in free recall did not seem to result from a short-term memory store. Subjects were presented with four study-test periods of 10 word lists, with a continual distractor task (20-second period of counting-backward).
Later research on short-term memory and working memory revealed that memory span is not a constant even when measured in a number of chunks. The number of chunks a human can recall immediately after presentation depends on the category of chunks used (e.g., span is around seven for digits, around six for letters, and around five for words), and even on features of the chunks within a category.
[1] [2] Dr. Benton developed the test to provide a shorter assessment for immediate nonverbal memory to supplement the popular digit span test, and selected a format that was resistant to both emotional and subject-tester influence. [3] The test was published in 1946, and is now currently in its 5th edition.

The Wechsler Memory Scale (WMS) is a neuropsychological test designed to measure different memory functions in a person. Anyone ages 16 to 90 is eligible to take this test. The current version is the fourth edition (WMS-IV) which was published in 2009 and which was designed to be used with the WAIS-
