摘　　要：产生效应指朗读的记忆成绩好于默读,然而目前还不清楚发音动作和声音在其中的作用。本研究采用fNIRS技术,考察大学生朗读、唇读、默读三种阅读方式时的记忆成绩和大脑激活模式。结果发现:(1)朗读和唇读的记忆成绩显著高于默读;(2)朗读和唇读时在初级运动皮层、布洛卡区和威尔尼克区的激活程度均显著大于默读时;(3)朗读时在威尔尼克区的激活程度显著大于唇读时。这表明,发音动作相对声音在产生效应中的作用更大。The production effect indicates that the items could be better remembered in loud reading compared to silent reading.MacLeod et al(2010)put forward the distinctiveness account to explain this effect,suggesting that items being read aloud are particularly distinctive compared to items being read silently,pronunciation improves memory.The distinctiveness account has been supported by many studies.In loud reading,articulation movements and sound whilst such do not exist in silent reading.In other words,loud reading involves explicit articulation movement and sound compared with silent reading.However,the effect of articulation movement and sound on the production effect is still not clear.In the present study,we recruited 32 right-handed healthy university students(14 boys,18 girls,Mage±SD=21.56±1.32years).The participants were asked to complete reading tasks in three reading modes:loud reading;silent mouthing(read silently while“mouthing”the words);silent reading(read silently without mouth movements).Functional near-infrared spectroscopy(fNIRS)was used to examine the brain cortical oxygenation changes during the tasks.Specifically,fNIRS data was acquired using the LABNIRS/16(Shimadzu Corporation,Kyoto,Japan),with a 5×6 multichannel probe frame including 15 sources and 15 detectors,49 channel montage,and the main areas of interest including the Primary Motor Cortex,Broca area,and Wernicke area.Before the official experiment,the participants practiced three reading modes.During the experiment,each participant completed three reading blocks,with each block containing three,one-minute reading passages(loud reading;silent mouthing;silent reading).Within the blocks,each reading task was intermixed with a 12s inter-stimulus interval(ISI)with a fixed cross-presenting on the screen.Sixty-second rest periods were placed before each block and after the final reading block.During the rest periods,the participants were instructed to look at a fixed cross in the middle of the monitor and to relax.The order of three diffe
