After reviewing the controlling factors of alterations in colour perception, their main characteristics and relevance for primary education, we report the results of applying a new test (TIDA) to a population of schoolchildren with ages ranging from 5 to 7 years. Its diagnostic validity and attractiveness to children are compared with two other tests (Ishihara and CUT). TIDA was highly appealing to children and gave a fair estimate of the severity of colour blindness, though its power to discriminate among different types of this problem has still to be improved.
Tras revisar las causas de aparición, características principales, y relevancia escolar de las alteraciones de la percepción del color, se informa de los resultados obtenidos aplicando un nuevo test ("TIDA") a una población escolar formada por 458 niños y 330 niñas, con edades comprendidas entre los 5 y 7 años. Su eficacia diagnóstica y nivel de atractivo se compararon con otros dos test (Ishihara y CUT). El TIDA mostró un alto nivel de atractivo, buenos niveles para diagnosticar la gravedad del daltonismo y niveles mejorables en cuanto al diagnóstico del tipo.
