Research on the WAIS WMI consistently shows that working memory capacity is strongly related to which broader cognitive ability?
Answer: General intelligence (g)
Working memory is one of the strongest correlates of general intelligence, reflecting fluid reasoning and attentional control.
An examinee with ADHD is most likely to show a characteristic pattern on the WAIS WMI of:
Answer: Depressed WMI relative to other index scores
ADHD is associated with deficits in attentional control and working memory, typically producing a lower WMI relative to other WAIS index scores.
Which of the following best describes the role of the phonological loop during Digit Span Forward?
Answer: It rehearses auditory-verbal sequences to maintain them briefly
The phonological loop maintains verbal sequences through subvocal rehearsal, which is the primary mechanism in Digit Span Forward.
In WAIS-IV standardization data, what is the approximate average raw Digit Span Forward score for adults aged 25–34?
Answer: 6–7 digits
Normative data show most adults in this age range can correctly repeat sequences of approximately 6–7 digits forward.
A low WMI score alongside an average Processing Speed Index (PSI) in a WAIS profile most strongly implicates difficulties in:
Answer: Active attentional control and mental manipulation
When PSI is intact but WMI is low, the deficit is specific to effortful working memory operations rather than general speed.
Letter-Number Sequencing items become progressively harder on the WAIS by:
Answer: Increasing the total number of elements in the sequence
Difficulty increases as more letters and numbers are added to each sequence, placing greater demands on working memory capacity.
Which population group typically shows the steepest age-related decline in WAIS WMI scores according to normative data?
Answer: Adults aged 75 and older
Working memory shows accelerating decline in the oldest age brackets, with adults 75+ showing the steepest normative drop on WMI.
