Recent evidence indicated that fraction pair type determined whether a particular fraction is processed holistically, componentially or in a hybrid manner. Going beyond previous studies, we investigated how participants adapt their processing of fractions not only to fraction type, but also to experimental context. To examine adaptation in fraction processing, we recorded participants' eye-fixation behaviour in a fraction magnitude comparison task. Participants' eye fixation behaviour indicated componential processing of fraction pairs with common components for which the decision-relevant components are easy to identify. Importantly, we observed that fraction processing was adapted to experimental context: Evidence for componential processing was stronger, when experimental context allowed valid expectations about which components are decision-relevant. Taken together, we conclude that fraction processing is adaptive beyond the comparison of different fraction types, because participants continuously adjust to the experimental context in which fractions are processed.
最近的证据表明，分数对类型决定了特定分数是整体加工、成分加工还是以混合方式加工。超越以往的研究，我们研究了参与者如何不仅将他们对分数的加工方式适应于分数类型，还适应于实验情境。为了检验分数加工中的适应性，我们在分数大小比较任务中记录了参与者的眼动注视行为。参与者的眼动注视行为表明，对于具有共同成分且决策相关成分易于识别的分数对进行成分加工。重要的是，我们观察到分数加工适应于实验情境：当实验情境允许对哪些成分与决策相关有合理预期时，成分加工的证据更强。综上所述，我们得出结论，分数加工在不同分数类型的比较之外具有适应性，因为参与者会不断调整以适应分数加工的实验情境。
