知觉流畅性对判断和决策的影响

流畅性是个体对加工信息难易程度的一种主观体验, 它分为知觉流畅性、概念流畅性、提取流畅性等。研究者通过操纵刺激与背景的颜色对比度、刺激的字体类型、清晰程度等因素来控制知觉流畅性, 发现知觉流畅性会影响一系列判断和决策任务, 如命题真实性、类别判断、偏好、熟悉性等。知觉流畅性既可以作为判断的直接线索也可以通过选择不同线索和认知策略来间接影响判断和决策。

Effects of Perceptual Fluency on Judgment and Decision

Fluency - the subjective experience of ease or difficulty associated with information processing – includes perceptual fluency, conceptual fluency, retrieval fluency, so on and so forth. Researchers manipulated perceptual fluency via controlling the figure-ground contrast, font, and clarity of stimuli and found that perceptual fluency has influences on a serial of judgment and decision, such as truth judgment, categorization, preference, familiarity and so on. It is assumed that perceptual fluency can both act as a direct cue and function in an indirect way by selecting various cues and cognitive strategies.
