title: Analysis of sequential letter matching tasks utilising lateralised tachistoscopic presentation.
abstract: Four experiments are reported in which sequential matches were demanded for double letter stimuli, the first stimulus pair was presented in central vision and the second in the left or right field. The responses were analysed according to the type of classification required (physical or nominal identify, or different). The results indicated that there were alterations in laterality patterns between retention intervals of 50 msec. and 990 msec. despite evidence for a prolonged and stable form of visual memory. These findings were incompatible with a model of the letter matching task which maps "name" codes to the left hemisphere and "visual" codes to the right.
