It is well known that the difference in performance between valid and invalid trials in the covert orienting paradigm (i.e., the cueing effect) increases as the proportion of valid trials increases. This proportion valid effect is widely assumed to reflect "strategic" control over the distribution of attention. In the present experiments we determine if this effect results from an explicit strategy or implicit learning by probing participant's awareness of the proportion of valid trials. Results support the idea that the proportion valid effect in the covert orienting paradigm reflects implicit learning not an explicit strategy.
众所周知，在隐蔽定向范式中，有效试验和无效试验之间的表现差异（即提示效应）随着有效试验比例的增加而增加。这种有效比例效应被广泛认为反映了对注意力分布的“策略性”控制。在本实验中，我们通过探测参与者对有效试验比例的意识，来确定这种效应是来自于明确的策略还是内隐学习。结果支持了这样一种观点，即在隐蔽定向范式中的有效比例效应反映了内隐学习而不是明确的策略。
