Instruction wording in Experiments 1 and 2.

All instructions in quotation marks were spoken, contents in parenthesis were acted out by an experimenter. The only difference between various conditions was the example given on Slide 3.所有置于引号内的指示均为口头表述，括号内的内容由实验者进行动作演示。不同实验条件间的唯一区别，即为第3张幻灯片（Slide 3）所给出的示例。
