In the present study, we examined how morphemic ambiguity is resolved using the visual-world paradigm. Participants were presented with Chinese bimorphemic words containing an ambiguous morpheme (analogous to the suffix -er in teacher and taller) and performed a visual search task. Their eye-movement patterns during target detection showed that (1) without a prior context, the dominant meaning of an ambiguous morpheme was more available than the subordinate one; (2) with a dominant-biased prior context, the subordinate meaning was still activated; and (3) a subordinate-biased prior context could inhibit the dominant interpretation. Therefore, both the frequency of the intended meaning and the prior contextual biases play a role in morphemic ambiguity resolution. The results are discussed with reference to models of ambiguity resolution and recent proposals of the graded nature of morphological effects.
在本研究中，我们使用视觉世界范式研究了词素歧义是如何被消解的。参与者被呈现包含有歧义词素的汉语双音节词（类似于后缀-er 在 teacher 和 taller 中），并完成了一项视觉搜索任务。他们在目标检测过程中的眼动模式表明：（1）在没有先前语境的情况下，歧义词素的主导意义比从属意义更易获得；（2）在有主导偏向的先前语境中，从属意义仍然被激活；（3）从属偏向的先前语境可以抑制主导解释。因此，意图意义的频率和先前的语境偏向都在词素歧义消解中发挥作用。研究结果结合了歧义消解模型和形态效应的渐变性质的最新提议进行了讨论。
