Wechsler Working Memory Index Flashcards

On the WPPSI-IV for young children, the Working Memory Index is composed of which type of tasks?

Answer: Picture-based memory tasks such as Picture Memory and Zoo Locations

The WPPSI-IV uses developmentally appropriate visual tasks like Picture Memory and Zoo Locations.

A clinically meaningful discrepancy between WMI and Processing Speed Index is best interpreted by:

Answer: Considering the full profile and background rather than a single number

Index discrepancies should be interpreted within the broader clinical and testing context.

Working memory as measured by the WMI is most closely linked to which brain region?

Answer: Prefrontal cortex

Working memory relies heavily on the prefrontal cortex and its executive functions.

If a child scores 115 on the WMI, this is best described as:

Answer: High Average

A score of 115 is one standard deviation above the mean, in the High Average range.

Which strategy can a person use to support weak working memory in daily life?

Answer: Breaking tasks into smaller steps and using written reminders

External supports like written lists and chunking reduce the load on working memory.

The Working Memory Index differs from short-term memory mainly because it requires:

Answer: Active manipulation of information, not just passive storage

Working memory involves manipulating information, whereas short-term memory is passive holding.

A very low WMI combined with average scores elsewhere would most likely prompt an examiner to:

Answer: Explore attention, learning, or anxiety factors further

An isolated low WMI signals the need to investigate attention, learning, or emotional factors.
