“…Animals and humans quickly learn predictive relationships between sensory inputs and their expected outcomes (Gallistel & Matzel, 2013), and if the relationship between sensory inputs and outcomes becomes predictable, neural activity (Alink, Schwiedrzik, Kohler, Singer, & Muckli, 2010) and learning are significantly reduced (Hogarth, Dickinson, Austin, Brown, & Duka, 2008;Kording & Wolpert, 2004;Orban & Wolpert, 2011;Pearce & Hall, 1980;Vanni-Mercier, Mauguiere, Isnard, & Dreher, 2009). This suggests that although the contiguity of events is important (Wheeler & Miller, 2008), the associative relationship between these events is crucial to learning. More specifically, when the relationship between a cue and an outcome is not predictable, but instead is uncertain, learning is enhanced.…”
