【摘要】：數(shù)字的加工方式一直是心理學(xué)家關(guān)注的焦點(diǎn),研究者在許多任務(wù)中發(fā)現(xiàn)健康被試對(duì)數(shù)量較小的數(shù)字存在微弱而穩(wěn)定的偏好,例如數(shù)字二分任務(wù)、數(shù)字探測(cè)任務(wù)和時(shí)序判斷任務(wù)等。這個(gè)現(xiàn)象的原因?qū)W界仍未達(dá)到統(tǒng)一,大量研究表明數(shù)字與空間具有緊密聯(lián)系,我們推測(cè)小數(shù)字偏好形成的原因與數(shù)字的空間表征方式相關(guān)。棱鏡適應(yīng)最初被發(fā)現(xiàn)對(duì)于忽視癥癥狀有良好的改善作用,越來(lái)越多的人使用棱鏡適應(yīng)作為調(diào)控空間注意的一種手段,在健康被試身上發(fā)現(xiàn)了感覺(jué)運(yùn)動(dòng)及高級(jí)認(rèn)知的改變。本研究的主旨是探究棱鏡適應(yīng)所造成的空間注意的改變,是否可對(duì)不同任務(wù)中的小數(shù)字偏好產(chǎn)生影響。研究一、二、三分別采用簡(jiǎn)單探測(cè)任務(wù)、時(shí)序判斷任務(wù)和同時(shí)性任務(wù)作為前后測(cè),中間加入左偏棱鏡、右偏棱鏡和平光鏡的適應(yīng),通過(guò)對(duì)比前后測(cè)中小數(shù)字偏好的效應(yīng)量差異來(lái)探究不同方向的空間注意轉(zhuǎn)移對(duì)小數(shù)字偏好的影響。結(jié)果發(fā)現(xiàn),僅在簡(jiǎn)單探測(cè)任務(wù)中,(左偏)棱鏡對(duì)小數(shù)字偏好有影響,這表明小數(shù)字偏好與數(shù)字的空間表征方式有關(guān)。而在時(shí)序判斷任務(wù)和同時(shí)性判斷任務(wù)中,棱鏡適應(yīng)對(duì)小數(shù)字偏好均無(wú)影響,表明棱鏡適應(yīng)所引發(fā)的空間表征變化對(duì)數(shù)字認(rèn)知的影響存在一定的任務(wù)特異性,暗示了棱鏡對(duì)涉及更多判斷和決策的任務(wù)作用有限。
[Abstract]:The way in which numbers are processed has always been the focus of psychologists. In many tasks, researchers found that healthy subjects had a weak and stable preference for smaller numbers, such as digital dichotomies. Digital detection task and timing judgment task. The cause of this phenomenon is still not uniform, a large number of studies show that the number and space have a close relationship, we speculate that the formation of the small number preference is related to the spatial representation of the number. Prism adaptation was initially found to have a good effect on the symptoms of neglect. More and more people use prism adaptation as a means to regulate spatial attention and find changes in sensory movement and advanced cognition in healthy subjects. The purpose of this study is to explore whether the change of spatial attention caused by prism adaptation can affect the small number preference in different tasks. Study 1, 2, and 3 respectively using simple detection tasks, timing judgment tasks and simultaneous tasks as pre and rear tests, adding left bias prism, right deviation prism and light mirror adaptation in the middle, The effects of spatial attention shift in different directions on the preference of small numbers were studied by comparing the difference of effect quantity of the preference of small and medium numbers before and after the measurement. The results show that only in simple detection tasks, the (left-sided) prism has an effect on the preference of small numbers, which indicates that the preference of small numbers is related to the spatial representation of numbers. In the tasks of timing judgment and simultaneous judgment, prism adaptation has no effect on the preference of small numbers, which indicates that the spatial representation change induced by prism adaptation has a certain task specificity. It suggests that prism has a limited role in tasks involving more judgment and decision-making.
