传统上，语义启动被认为是一种快速衰减的效应。提出了吸引子神经网络中长时间词启动的新观点。该模型预测在一定条件下的长期语义启动。也就是说，任务必须在足够的程度上进行语义级处理。这些预测在计算机模拟和3个实验中得到了证实。实验一表明，当目标词前面有多个语义相关的启动时，在语义判断任务上存在长滞后启动，而在词汇判断任务上不存在长滞后启动。实验2复制了语义决策的长期语义启动效应，每个目标只有一个启动。实验三采用长词表进行语义启动，延迟时间分别为0、4和8个项目。这是第一个实验，以证明语义启动效应跨越许多干预项目和持续时间远远超过几秒钟。
Semantic priming is traditionally viewed as an effect that rapidly decays. A new view of long-term word priming in attractor neural networks is proposed. The model predicts long-term semantic priming under certain conditions. That is, the task must engage semantic-level processing to a sufficient degree. The predictions were confirmed in computer simulations and in 3 experiments. Experiment 1 showed that when target words are each preceded by multiple semantically related primes, there is long-lag priming on a semantic-decision task but not on a lexical-decision task. Experiment 2 replicated the long-term semantic priming effect for semantic decisions with only one prime per target. Experiment 3 demonstrated semantic priming with much longer word lists at lags of 0, 4, and 8 items. These are the first experiments to demonstrate a semantic priming effect spanning many intervening items and lasting much longer than a few seconds.
