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

在联想学习中，人类注意到感觉线索，因为它们具有信息价值。从两个截然相反的角度来看，分配注意力是因为(A)线索是对随后结果的可靠预测，或者(B)线索导致对其结果的不确定性。B4项目使用了一系列预测性学习任务，考察了信息价值对外显注意力、学习速度、瞳孔定向、事件相关脑电位的N2PC成分以及对模糊刺激的感知的影响。我们的研究结果将进一步揭示联想学习中的注意过程。

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.
