【摘要】：創(chuàng)造性想象是指人們根據(jù)一定的目的和任務(wù),在頭腦中產(chǎn)生新穎表象的心理過(guò)程,這一過(guò)程對(duì)于創(chuàng)造活動(dòng)十分重要�？萍碱I(lǐng)域里重大發(fā)明的產(chǎn)生、藝術(shù)領(lǐng)域里典型形象的形成,都以在工程師和藝術(shù)家頭腦中能創(chuàng)造出新穎的表象為前提,所以創(chuàng)造性想象是創(chuàng)造性活動(dòng)得以順利展開(kāi)關(guān)鍵的認(rèn)知心理成分。離開(kāi)了創(chuàng)造性想象,一切創(chuàng)造活動(dòng)都難以完成。先前關(guān)于創(chuàng)造性想象的研究主要集中在兒童和青少年創(chuàng)造性想象的發(fā)展、創(chuàng)造性想象的測(cè)量以及創(chuàng)造性想象的認(rèn)知加工過(guò)程等行為學(xué)方面。然而,直到現(xiàn)在,創(chuàng)造性想象的神經(jīng)基礎(chǔ)仍鮮有研究涉及。為了檢驗(yàn)創(chuàng)造性想象產(chǎn)生過(guò)程中大腦的神經(jīng)機(jī)制,我們采用了功能核磁共振技術(shù),比較了三種實(shí)驗(yàn)條件(創(chuàng)造性想象、普通想象和控制條件)下被試的神經(jīng)活動(dòng)模式。創(chuàng)造性想象條件使用了經(jīng)典的概念結(jié)合產(chǎn)生新穎表象的范式(wisniewski,1996)。創(chuàng)造性想象條件要求被試產(chǎn)生與兩個(gè)概念結(jié)合相對(duì)應(yīng)的新穎表象,普通想象條件要求被試產(chǎn)生與一個(gè)普通概念相對(duì)應(yīng)的舊有表象,控制條件是使用六個(gè)字符作為基線。我們的研究假設(shè)是,相對(duì)于普通想象,創(chuàng)造性想象將會(huì)顯著地激活左側(cè)前額葉這一與創(chuàng)造性有著緊密聯(lián)系的腦區(qū)。我們的FMRI數(shù)據(jù)顯示,相對(duì)于普通想象條件或者控制條件,創(chuàng)造性想象條件明顯地激活了左側(cè)額下回BA47,BA45和左側(cè)額上回BA6。我們認(rèn)為左側(cè)額下回BA47負(fù)責(zé)較遠(yuǎn)距離語(yǔ)義聯(lián)系的形成,左側(cè)額下回BA45參與弱的語(yǔ)義聯(lián)系的形成,而左側(cè)額上回BA6卷入了與這些語(yǔ)義聯(lián)系相對(duì)應(yīng)心理表象的基本操作。本研究的結(jié)果第一次揭示了BA47,BA45和BA6是負(fù)責(zé)創(chuàng)造性想象條件下新穎表象的產(chǎn)生的關(guān)鍵神經(jīng)成分。這個(gè)研究關(guān)于創(chuàng)造性想象的神經(jīng)活動(dòng)模式的新發(fā)現(xiàn),豐富了人類高級(jí)認(rèn)知的神經(jīng)科學(xué)的知識(shí),加深了人們對(duì)于創(chuàng)造活動(dòng)神經(jīng)機(jī)制的理解,對(duì)創(chuàng)造性活動(dòng)的理論做出了重要貢獻(xiàn)。
[Abstract]:Creative imagination is a psychological process in which people produce novel images in their minds according to their goals and tasks. This process is very important for creative activities. The emergence of major inventions in the field of science and technology and the formation of typical images in the field of art presupposes the ability to create novel images in the minds of engineers and artists. Therefore, creative imagination is the key cognitive psychological component of creative activities. Without creative imagination, all creative activities are difficult to complete. Previous studies on creative imagination focused on the development of creative imagination in children and adolescents, the measurement of creative imagination and the cognitive process of creative imagination. Until now, however, the neural basis of creative imagination has rarely been studied. In order to examine the neural mechanism of the brain during the process of creative imagination, functional nuclear magnetic resonance (fMRI) was used to compare the neural activity patterns of the subjects under three experimental conditions (creative imagination, general imagination and control condition). Creative imagination conditions use classical concepts combined to produce novel representations (wisniewski,1996). The creative imagination condition requires the subjects to produce a novel representation corresponding to the two concepts, while the general imagination condition requires the subjects to produce an old representation corresponding to a common concept. The control condition is to use six characters as the baseline. Our study hypothesized that creative imagination would significantly activate the left prefrontal lobe a brain area closely related to creativity as opposed to ordinary imagination. Our FMRI data show that creative imagination conditions activate the left inferior frontal gyrus BA47,BA45 and the left superior frontal gyrus BA6. significantly, relative to normal or control conditions. We believe that the left subfrontal gyrus (BA47) is responsible for the formation of long distance semantic connections, the left inferior frontal gyrus (BA45) is involved in the formation of weak semantic connections, and the left suprafrontal gyrus (BA6) is involved in the basic operation of psychological representation corresponding to these semantic connections. The results of this study reveal for the first time that BA47,BA45 and BA6 are the key neural components responsible for the production of novel representations under creative imagination. The new findings of this study on the neural activity pattern of creative imagination enrich the knowledge of neuroscience of human advanced cognition, deepen the understanding of the neural mechanism of creative activity, and make important contributions to the theory of creative activity.
