中文摘要：

近年来,越来越多的证据表明知觉线索影响个体的高级认知——元记忆。元记忆指个体对自己学习和记忆活动的认知,其核心成分是监测和控制。研究发现,多种知觉线索（如字体大小、音量、文本清晰度、重量、亮度等）影响个体的元记忆监测（如学习判断和自信心评定）及控制（如学习时间分配）。这种影响可能是加工流畅性所致,也可能基于人们的信念产生。未来研究有必要进一步探究知觉线索影响元记忆监控的条件,并厘清加工流畅性和信念的具体作用。

英文摘要：

In recent years, increasing evidence has indicated that perceptual cues can affect higher level cognition, or metamemory. Metamemory refers to a person＇s cognitions about his or her own memory, consisting of two key components： monitoring and control. Studies have found that perceptual cues（such as font size, volume, clarity of text, weight, luminance, and so on） impacted on both metamemory monitoring（e.g., judgment of learning and judgment of confidence） and control（e.g., study time allocation）. It is assumed that processing fluency or beliefs may contribute to these effects. Further researches should be conducted to explore the conditions under which perceptual cues influence metamemory monitoring and control, and to clarify the specific contributions of processing fluency and beliefs to the process of perceptual cues affecting metamemory.
