Between the two attempts a distractor was introduced in the form of the SDMT
Furthermore, concurrent implementation of the MSNQ with a brief and wellestablished measure of processing speed (i.e., the SDMT
)  would be more appropriate for efficient cognitive screening in clinical and research settings.
Although results for part A of the TMT and the SDMT
were not statistically significant, results show that processing speed improved across the three time points.
They used two standardized and widely used neuropsychological measures (SDMT
and TMT) to assess visual scanning, information processing speed, and working memory.
The primary outcome was cognitive performance as measured by improvement in SDMT
, BVMT, and CVLT between groups compared to baseline.

Velocidad de procesamiento de informacion: se utilizaron el Trail Making Test A (TMT-A, (Tombaugh, 2004), que ademas evalua atencion visual sostenida, rastreo visual y habilidad grafomotora; el Symbol Digit Modalities Test (SDMT
, Smith, 2002), que es una prueba de atencion y rastreo visual, concentracion y velocidad psicomotora, y el Stroop (Golden, 2001) lectura, en el que se pide al sujeto que lea lo mas rapido posible columnas de palabras.
There was a significant difference in the scores of PASAT SRT I, SRT II, SDMT
and WLG tests between baseline and follow-up 1 and follow-up 2 tests (p=0.000l).
Tests included in the BICAMS are the Symbol-Digit Modalities Test (SDMT
)  as a measure of cognitive processing speed, California Verbal Learning Test-2 (CVLT-2)  as a measure of verbal learning and memory, and the Brief Visuospatial Memory Test-Revised (BVMT-R)  as a measure of visual learning and memory.

This led to the establishment of school development management teams (SDMT
) in compliance with the school development management model.
Here glycine betaine is synthesized by three successive N-methylation and the reactions are catalysed by two S-adenosyl methionine dependent methyl transferases, glycine sarcosine N-methyl transferase (GSMT), and sarcosine dimethylglycine N-methyl transferase (SDMT
