Speed of Processing: Tests and Factor Structure

In the present study we examined Speed of Processing derived from a number cognitive tests; response speeds were nearly automatic for tests with minimal load. The given to students across ages 8 20 in schools and colleges located various parts India. structure constellation test responses was determined by factor analyses. We report one stable speed 8-10 that splits into two separate but correlated factors 11-14,15-17, 18-20 representing contain letters numbers versus colour stimuli. Developmental changes four adjacent age groups examined; trajectory not consistently incremental, especially naming colours did increase beyond 11-14.In conclusion, fairly reasonable deconstruction concepts RAN has been presented this report. major components are encoding articulation, necessity distinguishing alpha-numeric time naming. later requires additional semantic access. At end, suggest follow-up research RAN(alpha-numeric&colour) should be viewed as part broader processing.Our objective is determine association between basic executive processes such flexibility,attention &inhibition working memory on hand other.Consequently search would involve speed, aware value correlation an sp eed.This will useful information or example investigations effect ageing functions. A worthy agenda future research. Keywords: Rapid Automatic Naming(RAN),Developmental Changes, Executive Functions DOI: 10.7176/JEP/13-30-11 Publication date: October 31 st 2022
