Normative data for the letter-cancellation task in school children

摘要

Aims:To establish the norms for the letter-cancellation task—a psychomotor performance task.Materials and Methods:Eight hundred nineteen school students were selected in the present study in an age range between nine and 16 years (M = 12.14; SD = 1.78 years). Subjects were assessed once for the cancellation task.Results:Both age and sex influenced performance on the SLCT; therefore, correction scores were obtained on the basis of these factors.Conclusions:The availability of Indian normative data for the SLCT will allow wider application of this test in clinical practice.
