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.
我们研究了自动语义启动中半球差异和促进作用的半球间转移，使用由同一类别但不相关的单词组成的启动-目标对（例如裙子-手套），以及空白目标基线条件。在启动和目标开始之间的短间隔（300毫秒）内测量反应时间和准确性，使用go/no-go任务来区分单词或非单词目标。与左视野（LVF）相比，右视野（RVF）中呈现的目标单词的反应时间得到了更大的促进，并且RVF中呈现的目标在两个视野中都得到了启动，而LVF中呈现的目标仅由LVF中的启动词启动。这些结果表明，两个半球在非常短的刺激开始不对称（SOA）时都能够进行自动启动，但跨半球启动仅发生在左半球。
