Left/right "fixed" responses to arrow targets are influenced by whether a masked arrow prime is congruent or incongruent with the required target response. Left/right "free-choice" responses on trials with ambiguous targets that are mixed among fixed trials are also influenced by masked arrow primes. We show that the magnitude of masked priming of both fixed and free-choice responses is greater when the proportion of fixed trials with congruent primes is .8 rather than .2. Unconscious manipulation of context can thus influence both fixed and free choices. Sequential trial analyses revealed that these effects of the overall prime context on fixed and free-choice priming can be modulated by the local context (i.e., the nature of the previous trial). Our results support accounts of masked priming that posit a memory-recruitment, activation, or decision process that is sensitive to aspects of both the local and global context.
对箭头目标的左/右“固定”反应会受到一个被掩蔽的箭头启动刺激与所需目标反应是否一致的影响。在固定试验中夹杂着模糊目标的试验中，对左/右“自由选择”反应同样会受到被掩蔽的箭头启动刺激的影响。我们发现，当启动刺激与目标一致的固定试验比例为0.8而非0.2时，固定反应和自由选择反应的掩蔽启动效应的强度会更大。因此，对情境的无意识操控能够影响固定反应和自由选择反应。序列试验分析表明，总体启动刺激情境对固定反应和自由选择反应启动效应的这些影响会受到局部情境（即前一次试验的性质）的调节。我们的研究结果支持了关于掩蔽启动效应的观点，这些观点假定存在一个对局部和全局情境方面都敏感的记忆招募、激活或决策过程。
