Words carry considerable information, but much of that information is not relevant in context. Research has shown that readers selectively activate and remember relevant information associated with words in different contexts, but it is not known when in processing this selection occurs. This experiment investigated whether context can change which properties are initially retrieved, using a speed-accuracy trade-off paradigm. Readers had to verify a property of a modifier-noun phrase (e.g., in the sentence Boiled celery is soft) within a specified interval, from 300-3,000 msec after presentation. Results revealed that properties associated with the noun alone were activated sooner than were properties that required integration of the modifier with the noun. Thus, context did not serve to influence the initial retrieval of properties but only to activate or suppress properties later in processing.
词汇承载着大量信息,但其中许多信息在特定语境中并不相关。研究表明,读者在不同语境中会有选择地激活并记住与词汇相关的信息,但目前尚不清楚这种选择在加工过程中的何时发生。本实验采用速度-准确性权衡范式,研究语境是否能够改变最初提取的属性。读者必须在呈现后的300至3000毫秒的特定时间间隔内,验证修饰语-名词短语的一个属性(例如,在句子“煮过的芹菜很软”中)。结果显示,与单独名词相关的属性比需要将修饰语与名词整合的属性更早被激活。因此,语境并未影响属性的初始提取,而仅在加工后期激活或抑制属性。
