On the Naming Speed Quantity subtest, Laurie named the quantity of squares inside a series of boxes as
quickly as possible. On this subtest, her score fell in the Average range (NSQ = 104). The NSL-NSQ
discrepancy comparison provides information about Laurie's performance across a pair of subtests
designed to measure naming automaticity. These tasks involve naming multiple dimensions and
alternating stimuli. The NSL subtest is particularly sensitive to reading and written expression skills,
while the NSQ subtest is possibly associated with mathematics skills. Laurie's performance suggests that
she has greater naming facility on tasks related to mathematical, rather than literacy, skills (NSL < NSQ,
BR = 2.2%). Although there was variability between Laurie's NSI subtest scores, her overall
performance was slightly below other children her age (NSI = 88, PR = 21, Low Average range, CI =
81-98). Low NSI scores may occur for many reasons, including visual-processing deficits, information
retrieval difficulties, weak language skills, poor naming skills, or generally slow cognitive functioning.
The Naming Speed process scores correspond to the NSL items. Laurie's Naming Speed Size-Color-
Object (NSsco) process score reflects her ability to identify elements by their size, color and object
attributes, while her Naming Speed Letter-Number (NSln) process score reflects her ability to name
letters and numbers, as quickly as possible. When asked to quickly say the name, color, and size of
common objects, her rate was slow compared to others her age (NSsco = 73). However, when she was
also required to name letters and numbers, her speed became significantly faster, and was compared to
her same-age peers (NSln = 121). A discrepancy comparison between NSsco and NSln provides
additional insight regarding how Laurie's performance on the NSL subtest varied when letters and
numbers were added to the naming task. Laurie's performance may suggest a lapse in attention or
motivation during the Naming Speed Size-Color-Object task. It is also possible that she more easily
employs successful strategies while progressing across tasks or she more readily improves with
experience and practice, relative to her same-age peers (NSln > NSsco; BR = 0.0%). Observational data
about her behavior, attention, concentration, and motivation during this subtest should also be
considered.
Symbol Translation
The Symbol Translation Index (STI) provides a broad estimate of visual-verbal associative memory. The
STI is based on the Immediate Symbol Translation (IST), Delayed Symbol Translation (DST), and
Recognition Symbol Translation (RST) subtest scores. She was shown symbols and taught the word that
each symbol represented. She was then asked to recall these associations immediately (IST), after a 20-
30 minute delay (DST), and in a multiple-choice recognition format (RST). These measures enhance the
assessment of children suspected of having learning problems or declarative memory impairment, rather
than overall intellectual ability. When interpreting her STI subtest scores, it is important to remember
that DST and RST performance are dependent upon that of IST. Laurie's overall performance across
these three tasks was evenly developed. She showed age-appropriate memory skills across all three
conditions, and her overall performance was Average compared to same-age peers (STI = 108, PR = 70,
CI = 101-114). An NSI vs. STI discrepancy comparison offers insight regarding her relative strengths
and weaknesses within the storage and retrieval domain. Her STI score was significantly stronger than
her performance on the NSI (STI > NSI; BR = 10.0%). This suggests that learning and memory for
recently acquired visual-verbal associations is a strength relative to rapid access of previously acquired
visual-verbal associations. Laurie's ability to store and accurately retrieve information is stronger than
her naming fluency and automaticity.
