提出了一种调度任务性能的双瓶颈模型。中心瓶颈会阻止重叠任务中的中心进程并行运行。响应启动瓶颈阻止2个响应紧密连续地启动。重叠任务的响应要求进行了操纵，以证明后者的瓶颈的存在，并评估其作用，在划定的重叠任务的性能。在几个实验中，消除这一瓶颈导致了一个强大的减少unadditive的相互作用，作为并行处理的关键指标，在并行任务的性能。结果表明，这些相互作用主要是由反应启动瓶颈，而不是中央瓶颈，并建议知觉识别和分类需要中央瓶颈。
A dual-bottleneck model for overlapping-task performance is proposed. A central bottleneck prevents central processes in overlapping tasks from operating in parallel. A response-initiation bottleneck prevents 2 responses from being initiated in close succession. Response requirements of the overlapping tasks were manipulated in order to demonstrate the existence of the latter bottleneck and to assess its role in delimiting overlapping-task performance. In several experiments, elimination of this bottleneck resulted in a strong reduction of underadditive interactions that serve as key indicators of parallel processing in overlapping-task performance. Results indicate that these interactions were caused primarily by the response initiation bottleneck instead of the central bottleneck and suggest that perceptual identification and categorization require the central bottleneck.
