Electrodermal complexity during the Stroop Colour Word Test

Abstract The aim of our study was to test whether and how the proficiency level in L2 affects the amount of within-language interference in Stroop colour word test (Polish as L1, English as L2); as well as to test whether and how the proficiency level in L2 affects colour naming speed in this L2, based on a study on 50 Polish students (age M = 20.8, SD = 1.6) at varying levels of English proficiency and age of acquisition > 7. The English version of Golden et al. (2002) Stroop Colour and Word Test and its Polish counterpart were used. The results show that in late unbalanced bilinguals the within-language interference was smaller in L2 than in L1 and its amount was not affected by L2 proficiency level; and that colour naming was slower in L2 than in L1, and the scores were not affected by L2 proficiency level. The implications of the study are discussed, concerning, among others, L2 processing in late unbalanced bilinguals. The popular claim that the pattern of the interplay between inter- and intra-linguistic interference in Stroop colour word test relates to proficiency level in L2 is challenged.

Background:Cognitive impairment in multiple sclerosis (MS) often involves attentional deficits. The Stroop colour word test, a measure of attention, lacks current normative data for an english-speaking North american MS population. Further some authors suggest the Stroop actually measures processing speed.Objective:To generate normative data for the Stroop colour word test that can be used for a Canadian or North american MS population and to examine the relationship between processing speed tests - the Paced auditory Serial addition Test (PASAT) and Symbol Digit Modalities Test (SDMT) - and the Stroop.Results:Data from 146 healthy subjects aged 18-56 was collected. age was significantly although weakly correlated with general intelligence (r=0.168, p=0.043) assessed with the North american adult Reading Test (NAART), and education (r=-0.313, p<0.001). No demographic variables were associated with SDMT or PASAT. age had a low-moderate negative correlation (r=-0.403, p<0.001) with Stroop scores. The mean (±standard deviation, SD) Stroop score was 45.4(10.4). The z-score can thus be calculated as [(X-45.4)/10.4]. if adjusted for age, Xadj = [X-(-0.47)(age-37.5)] and is substituted for X. in a comparison MS population consisting of 75 randomly selected patients from the MS Cognitive clinic, Stroop and PASAT performance were not related. a relationship existed between Stroop and SDMT scores but only 12.2% of the Stroop score variance was explained by the SDMT. Therefore, the Stroop measures selective attention independently of processing speed.Conclusion:This data can be used to determine impaired attention in MS patients.
