【摘要】：以聲旁在左和在右的漢字形聲字為刺激材料,以聲旁位置、字頻和規(guī)則性為變量,采用詞匯判斷(實(shí)驗(yàn)一)和詞匯命名(實(shí)驗(yàn)二)為實(shí)驗(yàn)任務(wù),使用在一側(cè)視野短暫呈現(xiàn)閃爍的刺激光點(diǎn)吸引對側(cè)半球的注意資源、以使另一側(cè)半球單獨(dú)對注視點(diǎn)處的刺激進(jìn)行加工的新穎的偏側(cè)化研究范式,來探究聲旁位置對漢字形聲字識別的影響及這種影響在兩半球之間是否有差異,并且考察這種差異在需要較多正字法加工的任務(wù)(詞匯判斷任務(wù))和需要較多語音加工的任務(wù)(命名任務(wù))中的表現(xiàn)。 實(shí)驗(yàn)一的結(jié)果顯示：對于真字刺激材料,干擾刺激位置的主效應(yīng)顯著,左干擾條件下的判斷反應(yīng)時短于右干擾條件,而對所有刺激、假字刺激以及真字刺激材料,錯誤率數(shù)據(jù)的干擾刺激位置的主效應(yīng)不顯著；實(shí)驗(yàn)結(jié)果中出現(xiàn)了逆轉(zhuǎn)的規(guī)則性效應(yīng),以及左干擾-聲旁在右字、右干擾-聲旁在左字的反應(yīng)模式的對應(yīng)關(guān)系。實(shí)驗(yàn)二的結(jié)果顯示：反應(yīng)時數(shù)據(jù)的干擾刺激位置的主效應(yīng)不顯著,但是錯誤率數(shù)據(jù)中的干擾刺激位置的主效應(yīng)是顯著的,右干擾條件下的錯誤率高于左干擾條件；出現(xiàn)了聲旁位置、字頻和規(guī)則性的交互效應(yīng),無論聲旁是在左還是在右,高頻規(guī)則字和高頻不規(guī)則字的命名時間都沒有差異,低頻的聲旁在左的不規(guī)則字命名快于規(guī)則字、低頻的聲旁在右的規(guī)則字命名快于不規(guī)則字。 實(shí)驗(yàn)結(jié)論有：在詞匯判斷任務(wù)中,大腦對聲旁在左和聲旁在右字的加工,分別采用右半球(右干擾條件)和左半球(左干擾條件)的加工模式；在命名任務(wù)中,聲旁位置和字頻共同影響規(guī)則性的表現(xiàn),聲旁在左低頻字出現(xiàn)了規(guī)則性效應(yīng)的逆轉(zhuǎn)、聲旁在右的低頻字出現(xiàn)的是規(guī)則性效應(yīng)；左半球是詞匯加工的優(yōu)勢半球,表現(xiàn)在左半球既具有一定的正字法加工的能力又在語音信息的加工上具有一定的優(yōu)勢；字頻是漢字形聲字的一種重要的整字屬性,頻率效應(yīng)在所有的情況下都會表現(xiàn)出來,并且高、低頻字的規(guī)則性效應(yīng)的表現(xiàn)形式不同。
[Abstract]:The Chinese characters with sound side on left and right were used as stimulus materials, with the position, frequency and regularity of sound side as the variables, and lexical judgment (experiment 1) and vocabulary naming (experiment 2) as experimental tasks. A novel lateralization paradigm for the processing of stimuli at a fixed point on the other side of the visual field using a transient flicker of stimuli in one visual field to attract attention resources from the contralateral hemispheres in order to enable the other hemisphere to process the stimuli at the fixation points alone. To explore the effect of the sound side position on the recognition of Chinese phonetic characters and whether there is a difference between the two hemispheres. The difference is also investigated in the tasks that require more orthographic processing (lexical judgment tasks) and tasks requiring more phonological processing (naming tasks). The results of experiment 1 showed that the main effect of interfering position was significant for true word stimuli, and the judging reaction time under left interference was shorter than that under right interference, while for all stimuli, false word stimuli and true word stimuli, the response time was shorter than that of right interference, but for all stimuli, false word stimuli and true word stimuli, The main effect of the interference of the error rate data on the stimulus position was not significant. The experimental results show that there is a regular effect of reversal and the corresponding relationship between the reaction modes of left interference-sound side in right word and right interference-sound side in left word. The results of experiment 2 show that the main effect of the interference stimulus position of the response time data is not significant, but the main effect of the interference stimulus position in the error rate data is significant, the error rate under the right interference condition is higher than that under the left interference condition. There is no difference in the naming time between the high frequency regular word and the high frequency irregular word, regardless of whether the sound side is left or right, and the low frequency irregular word on the left side is faster than the rule word. Regular words with low frequency sound on the right are named faster than irregular characters. The experimental results are as follows: in the lexical judgment task, the right hemisphere (right interference condition) and the left hemisphere (left interference condition) are used in the processing of the right side and the right side of the brain. In the naming task, the sound side position and the word frequency affect the performance of the rule together, the sound side in the left low frequency word appears the regular effect reversal, the sound side in the right low frequency word appears the rule effect; The left hemisphere is the dominant hemisphere in lexical processing, which is manifested in the fact that the left hemisphere not only has the ability of orthographic processing but also has certain advantages in the processing of phonetic information. Word frequency is an important whole character attribute of Chinese phonetic characters. The frequency effect is shown in all cases, and the regular effects of high and low frequency characters are different in form.
