To investigate strategic control over response initiation in word reading, the authors introduce the tempo-naming task. Relative to baseline performance in the standard-naming task, participants were induced to respond with faster latencies, shorter durations, and lower levels of accuracy by instructing them to time response initiation with an experimentally controlled tempo. The tempo response cue attenuated stimulus effects, and as faster tempos reduced latencies, the number of spelling-sound errors remained constant, whereas the number of word, nonword, and articulatory errors increased. To explain these results, the authors propose input gain as a mechanism of control over processing speed. The experimenters sketch how input gain could account for the current results as well as for the results from stimulus-blocking experiments testing the route emphasis and time criterion hypotheses of strategic control.
为了研究单词阅读中反应启动的策略控制，作者引入了节奏命名任务。相对于标准命名任务中的基线表现，通过指示参与者按照实验控制的节奏来计时反应启动，促使他们以更快的潜伏期、更短的持续时间和更低的准确率做出反应。节奏反应提示减弱了刺激效应，并且随着更快的节奏缩短了潜伏期，拼写-发音错误的数量保持不变，而单词、非单词和发音错误的数量增加。为了解释这些结果，作者提出输入增益作为控制处理速度的一种机制。实验者概述了输入增益如何解释当前结果以及来自测试策略控制的路径强调和时间标准假设的刺激阻断实验的结果。
