为了检验即刻学习判断对内外部线索的敏感性，实验一被试为22名高中生，材料为三列含15个词语的清单，先逐个呈现词语系列位置信息，被试在学习前进行即刻学习判断，结果发现学习判断有显著首因效应，表明学习判断对系列位置信息这一外部线索比较敏感。实验二被试为20名高中生，先逐个呈现词语系列位置信息，被试在学习后进行即刻学习判断，结果发现学习判断同样有显著首因效应，表明学习判断对内部线索的敏感性并未强于外部线索。

Two experiments were conducted to further explore the effects of intrinsic and extrinsic cues on immediate judgments of learning. In the first experiment, 22 senior high school students were asked to learn a list of words. The serial position information of item was present to participants whom were required to make immediate judgments of learning before learning. The result was that there were primacy effects in immediate judgments of learning. It was suggested that the immediate judgments of learning were sensitive to extrinsic cues. In the second experiment, the serial position information of item was present to another 20 senior high school students whom were required to make immediate judgments of learning after learning. The result was that there were primacy effects in immediate judgments of learning as well. It was suggested that there was no more sensibility of intrinsic cues than extrinsic cues to immediate judgments of learning.
