We explore the hypothesis that induction of holistic or analytic strategies influences comprehension and processing of highly contextualized expressions of ordinary language, such as irony. Twenty undergraduate students were asked to categorize as coherent or incoherent a group of sentences. Each sentence completed a previous story, so that they could be ironical, literal or nonsensical endings. Participants were asked to evaluate whether each sentence was coherent or incoherent. Half of them were initially instructed to consider whether the sentences made sense (holistic condition); the other half were instructed to consider whether the sentences were congruent or incongruent (analytic condition). Behavioral responses and Event Related Potentials were registered during the experiment. Both behavioral and electrophysiological results allow clearly distinguishing between the holistic and the analytic strategies. The fact that the same set of stimuli elicits different ERP waveforms, depending on the strategy with which they are analyzed, suggests that different cognitive processes and different areas of the brain are operating in each case.
我们探讨了这样一种假设，即整体或分析策略的诱导会影响对高度情境化的日常语言表达（如反讽）的理解和处理。20名本科生被要求将一组句子分类为连贯或不连贯。每个句子都是一个先前故事的延续，因此它们可能是具有反讽意味的、字面意思的或无意义的结尾。参与者被要求评估每个句子是连贯还是不连贯。其中一半人最初被指示思考句子是否有意义（整体条件）；另一半人则被指示思考句子是否一致或不一致（分析条件）。实验过程中记录了行为反应和事件相关电位。行为和电生理结果都清楚地表明了整体策略和分析策略之间的区别。同一组刺激根据分析它们的策略引发不同的ERP波形，这一事实表明在每种情况下都有不同的认知过程和不同的脑区在起作用。
