中文句子與圖形的驗證實驗指出:在句子述詞與圖形含有多個屬性時，肯定句「對」、「錯」的反應時間差距縮短，「錯的否定句」之反應時間較「對的否定句」為長。此可能由於所需比較展性的數目及再取出否定詞的難易兩個因素造成的。實驗一將屬性數目如為三個，結果肯定句「對」、「錯」反應時間的差距更短，「錯的否定句」之反應較「對的否定句」更慢。實驗二將極性符號置於每一屬性前，使再取出否定詞無難易之差異，結果「錯的否定句」之反應較「對的否定句」為快。此二實驗之結果支持「所需比較屬性之數目及再取出否定詞的難易為多屬性句子與圖形驗證歷程中產生影響的因素。並且受試著驗證多屬性句子之歷程是將之簡化為單一屬性驗證歷程之重複進行。

　　　　　Previous sentence-picture verification experiments indicate that a decrease in the difference between true affirmative RTs and false affirmative RTs was obtained for the sentences and pictures depicting objects of multiple attributes, and that false negative RTs were longer than true negative RTs. The finding was hypothesized (Liu and Liang, 1977) to be due to a difficulty in retrieving the negative polarity marker when an object described in a sentence contained more than one attribute. In Experiment I the number of attributes was increased to three. In Experiment 2 anegative polarity marker was placed before each of the sentence elements describing attributes of an object. The results of two experiments support the retrieval hypothesis. It was further noted that subjects tended to reduce "multi-attribute" sentences to single-attribute sentences in the courseof verification process. A tentative theory was briefly outlined.
