ABSTRACT
Aim: The aim of the study was to develop colour-concept interference paradigm to explore the possibility of using the Stroop interference effect to measure differences in linguistic conceptual depth in children.
Method: The colour-concept Stroop test consisted of five tasks – Colour Naming (CN), Easy-Object Colour-Naming (EO-CN), Difficult-Object Colour-Naming (DO-CN), Easy-Object Naming (EO-N) and Difficult-Object Naming (DO-N). The participants were 30 preschool children, 15 male and 15 female, mean age 4.6 years and 4.7 years respectively, (range 4.3 to 4.11 and 4 to 4.9 years), selected randomly from two English medium urban schools.
Procedure: The picture stimuli were presented through power-point slides-show on a Dell laptop (screen width 14 inches by 7.8 inches). Each set started with a blank screen for 200 ms, followed by a fixation cross of 500 ms. The onscreen stimulus duration was 1.5 seconds. The children were instructed to name colours, the colour of easy and difficult objects and then name the easy and difficult objects. The verbal responses were recorded on Pratt software (version 6.0.33 updated, 2017) for reaction time analysis.
Results: The differences between the mean reaction time and mean interference between easy object colour naming and difficult object colour naming was significant.
Conclusion: The colour-concept Stroop interference paradigm can be used to measure differences in linguistic conceptual depth. The implications of these findings are found in the discussion.
