The results of the biological pathways analysis of all the speed measures – using ALIGATOR software – are shown in Appendix CSupplementary Table 2. Pathways which overlapped across measures are shown in Table 3. Most of these were part of the biological process category: the three terms associated with inspection time and the speed factor related to vascular process; the two terms associated with simple RT and 4-choice RT were related to biosynthetic process; while the term associated with inspection time and 8-choice RT was a renal system process involved in regulation of systemic arterial blood pressure. The cellular component associated with the choice RT measures comprised terms that were all related to organelle and cell components. The three terms represented in the molecular function category associated with simple RT, choice RT, inspection time and digit symbol were in different pathways.
