Data

Novel word learning task with (a) 4 <i>object labelling</i> trials showing a single novel object (plus 3 filler trials with a familiar object) and asked "What’s this?" or "What is this called?"; (b) 6 <i>word recognition</i> trials showing 2 novel objects (labelled during teaching) plus a third novel object (presented during teaching but never labelled) and asked to "Point to the [object label]!" or "Show me the [object label]!" (plus 4 filler trials each with 3 familiar objects). For word recognition, indications (points/gestures) toward the labelled (target) object were counted. Gaze to the target was measured but not reported. Participants then completed 4 generalization trials with functionally similar but perceptually different objects.本数据集为新词学习任务，包含两类试次环节：(a) 4次客体命名（object labelling）试次，每次仅呈现单个新异客体（另有3次以熟悉客体为刺激的填充试次），并向被试提问"这是什么？"或"这个叫什么？"；(b) 6次词汇再认（word recognition）试次，每次呈现2个教学阶段已完成命名的新异客体，以及1个教学阶段出现但未被命名的新异客体，要求被试"指向[客体标签]！"或"给我展示[客体标签]！"，此外包含4次填充试次，每次均呈现3个熟悉客体。在词汇再认试次中，指向已命名（目标）客体的动作（手指点指或手势）将被计入得分。实验记录了被试注视目标客体的情况，但未对外报告该数据。随后，被试完成4次泛化试次，刺激为功能相似但感知特征不同的客体。
