社会认知中印象形成的启动效应研究──频因、近因效应

A STUDY OF THE PRIMING EFFECT OFIMPRESSION FORMATION IN SOCIALCOGNITION: FREQUENCY AND RECENCYEFFECT

本文以社会认知为出发点，考察印象形成的启动效应，它采用性质不同的成语作为实验材料，并操纵启动刺激的结构，系统探讨了印象形成的启动效应中原因与近因效应，结果发现：当呈现表示同一品质但性质相反的成语时，如果启动刺激和目标刺激之间不延迟，则近因在启动效应中起作用，但在延迟情况下，频因在启动效应中占优势；同时随着延迟的出现，启动效应明显变小。实验结果支持启动效应的突触模式说；

This paper explores the priming effect ofimpression formation in the area of social cognition. The authors adopted some Chinese idioms with differentmeanings as materials, and manipulated the struCtureof priming stimuli. The primng effect of impressionformation and the frequency and recency effect werestudied. The results showed: when idioms with thesame trait but opposite meanings were displayed, andthere wasn't a delay between the priming stimulus andthe target stimulus, the recently primed stimulus influenced the priming effect. Otherwise, the frequentlyprimed stimulus would be predominant in the primingeffect. And as the delay increased, the priming effectdeclined obviously. This result confirmed the synapse-model theory.
