中文摘要 在我們的日常生活中,許多物體會有”兩個眼睛在上面,一個嘴巴在下面”這種看起來像臉的結構。在一個MEG的研究中,Hadjikhani(2009)發現受試者的臉孔選擇區-FFA對於像臉物體的反應與臉孔相似,提供了第一個對像臉物體的神經科學證據。然而,像臉物體在本質上依然是物體,所以他應該也會引發物體選擇區-LOC的反應。為了探討FFA與LOC在看像臉物體時的關係,我們使用行為實驗與功能性核磁共振造影(fMRI)實驗。受試者在fMRI實驗中分別對刺激圖片做臉孔/物體以及像臉/不像臉的判斷。首先,行為實驗的結果顯示像臉物體的平均反應時間顯著長於臉孔及物體,顯示像臉物體額外的反應衝突時間。第二,fMRI實驗結果顯示,當受試者做不同的判斷時,作業要求不同會影響大腦在臉孔與物體選擇區的神經反應。
英文摘要 In daily lives, many objects with their “two-eyes-on-top, one-mouth-below" configurations, look like human faces. In one MEG study, Hadjikhani (2009) found that subjects' face-selective region-FFA, responded similarly to those “face-like objects" as to faces, providing the first neuroscientific support of those “face-likeness” impressions. However, face-like objects are by default objects, so they should active object-selective region-LOC as well. To investigate the interaction between FFA and LOC in viewing face-like objects, we use behavioral and fMRI methods to disentangle their relations. Subjects do speeded face/object and facelike/non-facelike judgments in fMRI experiments. First, the behavioral results show that the reaction time of face-like objects are significantly longer than that of faces or objects, suggesting the extra conflict reaction time of facelike-objects. Second, the fMRI experiment shows that when using different judgments, task demands would affect brain neuron responses in face- and object- selective regions.
