Applying Bloch's law to visual word recognition research, both exposure duration of the prime and its luminance determine the prime's overall energy, and consequently determine the size of the priming effect. Nevertheless, experimenters using fast-priming paradigms traditionally focus only on the SOA between prime and target to reflect the absolute speed of cognitive processes under investigation. Some of the discrepancies in results regarding the time course of orthographic and phonological activation in word recognition research may be due to this factor. This hypothesis was examined by manipulating parametrically the luminance of the prime and its exposure duration, measuring their joint impact on masked repetition priming. The results show that small and non-significant priming effects can be more than tripled as a result of simply increasing luminance, when SOA is kept constant. Moreover, increased luminance may compensate for briefer exposure duration and vice versa.

SOA 没有揭示快速启动实验中认知加工的绝对时间过程☆

将布洛赫定律应用于视觉词识别研究，素数的曝光时间和亮度决定素数的整体能量，进而决定启动效应的大小。然而，使用快速启动范式的实验者传统上只关注启动和目标之间的 SOA，以反映所研究的认知过程的绝对速度。在单词识别研究中，关于正字法和语音激活的时间过程的结果的一些差异可能是由于这个因素造成的。通过参数化操纵素数的亮度及其曝光持续时间，测量它们对掩蔽重复素数的联合影响来检验这一假设。结果表明，当 SOA 保持恒定时，简单地增加亮度可以使小的和不显着的启动效应增加三倍以上。此外，增加的亮度可以补偿较短的曝光持续时间，反之亦然。
