Automatic semantic priming in the left and right hemispheres

We investigated hemispheric differences and inter‐hemispheric transfer of facilitation in automatic semantic priming, using prime‐target pairs composed of words of the same category but not associated (e.g. skirt‐glove), and a blank‐target baseline condition. Reaction time and accuracy were measured...

Description
Summary:We investigated hemispheric differences and inter‐hemispheric transfer of facilitation in automatic semantic priming, using prime‐target pairs composed of words of the same category but not associated (e.g. skirt‐glove), and a blank‐target baseline condition. Reaction time and accuracy were measured at short (300 ms) intervals between prime and target onsets, using a go/no‐go task to discriminate between word or non‐word targets. Reaction times were facilitated more for target words presented in the right visual field (RVF) compared to the left visual field (LVF), and targets presented in RVF were primed in both visual fields, whereas targets presented in LVF were primed by primes in the LVF only. These results suggest that both hemispheres are capable of automatic priming at very short stimulus onset asymmetries (SOA), but cross‐hemisphere priming occurs only in the left hemisphere.
