Effects of informational value on perception and attention in associative learning. (B04)

在联想学习过程中，人类注意到感官线索，因为它们的信息价值。从两个截然相反的角度来看，注意力的分配是因为（a）一个线索是一个可靠的预测随后的结果或（B）一个线索诱导其后果的不确定性。项目B4使用了一系列的预测学习任务，以检查信息价值的影响，外显注意，学习率，瞳孔定向，N2PC组件的事件相关的脑电位，和模糊刺激的感知。我们的研究结果将进一步阐明在联想学习的注意过程。

During associative learning humans attend to sensory cues because of their informational value. From two diametrically opposed perspectives attention is allocated because (a) a cue is a reliable predictor of a subsequent outcome or (b) a cue induces uncertainty about its consequence. Project B4 uses a range of predictive learning tasks to examine the effects of informational value on overt attention, learning rate, pupillary orienting, the N2pc component of event-related brain potentials, and the perception of ambiguous stimuli. Our results will shed further light on attentional processes in associative learning.
