  • Title: Hemispheric semantic priming in the single word presentation task.
    Author: Koivisto M, Hämäläinen H.
    Journal: Neuropsychologia; 2002; 40(7):978-85. PubMed ID: 11900750.
    Abstract:
    Functional brain asymmetries in semantic activation were studied by presenting categorically related (e.g. TABLE-BED) or unrelated primes and targets to the left visual field (LVF)/right hemisphere or to the right visual field (RVF)/left hemisphere in the single word presentation lexical decision task. The results showed that the primes in the RVF/left hemisphere primed lexical decisions to the targets both in the RVF and in the LVF. However, the primes in the LVF/right hemisphere did not induce any priming in the LVF or RVF. These results suggest that the left hemisphere automatically activates categorically related meanings in both hemispheres. The role of the right hemisphere in automatic semantic processing may be very limited.
