采用同时记忆任务和字母命名任务，考察了言语（实验1）和非言语（实验2）记忆负荷对负启动的影响。在这两个实验中，负启动只有在零记忆负荷的条件下才是可靠的，这表明有助于负启动的过程是资源需求和依赖于无域资源池。负启动的个体差异，如高工作记忆容量的受试者表现出可靠的负启动，而低工作记忆容量的受试者没有。结果表明，负启动效应是由控制性注意分配引起的，工作记忆容量的个体差异与有效处理无关信息的能力有关。
The effect of a verbal (Experiment 1) and a nonverbal (Experiment 2) memory load on negative priming was investigated by employing a concurrent memory task with a letter naming task. Across both experiments, negative priming was reliable only under conditions of zero memory load, suggesting that the processes that contribute to negative priming are resource demanding and dependent on a domain-free resource pool. Individual differences in negative priming were observed, such that high working memory capacity subjects showed reliable negative priming whereas low working memory capacity subjects did not. The results suggest that the negative priming effect results from allocation of controlled attention and that individual differences in working memory capacity correspond to the ability to efficiently handle irrelevant information.
