However, the neural mechanisms of visual masking are unknown, so it is at present unclear if or how these altered responses relate to such masking.
Interactions of group by forward versus backward masking were not significant, suggesting that deficits in forward and backward masking were comparable.
If this attentional component becomes less robust with age, it would contribute to a steeper decline with age for backward, as compared to forward, masking.
Two of the masking conditions showed increased rates of decline in backward, compared to forward, masking.
It is not known, however, if visual backward masking deficit can account for semantic priming disturbance in schizophrenia.
Green et al. (1999) related visual backward masking deficits in patients with schizophrenia to a failure to establish cortical oscillations in the gamma range.
Magnocellular and parvocellular contributions to backward masking dysfunction in schizophrenia.
These were computerized versions of conditions that had been administered with tachistoscope in our previous studies of visual masking.
