Backward visual masking in children and adolescents: sensory transmission, accrual rate and asymptotic performance.
We have applied the Lagged Accrual Model of visual backward masking to a group of children (aged 10) and a group of adolescents (aged 15). The two groups did not differ on sensory transmission time, indicating that the speed of sensory transmission has already attained its maximum by age 10. The older group showed a significantly greater rate of information accrual and a greater amount of information extraction. An application of the model to previously published data revealed that very young children (aged 5) have slower sensory transmission times.
