Objective measures of baby schema (cf. Glocker et al. [2]).

Following Glocker, Langleben, Ruparel, Loughead, Gur, et al. [2] we measured head length (hl) face width (fw), forehead length (fol), face length (fal), eye width (ew), nose length (nl), nose width (nw), and mouth width (mw) to quantify baby schema. According to Glocker, Langleben, Ruparel, Loughead, Gur, et al., the following facial parameters capture baby schema: face width as an absolute measure in pixels and 5 proportion indices representing the relative size of one facial measure to another (fol/fal, ew/fw, nl/hl, nw/fw, mw/fw). The table shows the 6 parameters for each face category and for cute and less cute faces as well as for the mean across cute and less cute faces within a face category. High baby schema faces have larger fw, fol/fal, and ew/fw than low baby schema faces. By means of simple regression analyses we tested whether cute and less cute infant faces significantly differ from each other in the 6 parameters. In our sample there were significant differences in the expected direction between cute and less cute infants for Caucasian faces in face width (p = .018) and the ratio of forehead length to face length (p = .014). No other differences between cute and less cute infant faces were significant.Objective measures of baby schema (cf. Glocker et al. [2]).参照Glocker、Langleben、Ruparel、Loughead、Gur等学者[2]的研究方法，我们对头长（head length, hl）、面宽（face width, fw）、额长（forehead length, fol）、面长（face length, fal）、眼宽（eye width, ew）、鼻长（nose length, nl）、鼻宽（nose width, nw）及嘴宽（mouth width, mw）进行测量，以此量化婴儿图式（baby schema）。根据Glocker等学者的研究，以下面部参数可用于表征婴儿图式：以像素为绝对单位的面宽，以及5项比例指数，用于反映单一面部指标与另一指标的相对大小，具体为额长/面长、眼宽/面宽、鼻长/头长、鼻宽/面宽、嘴宽/面宽。本表格展示了每一类面部、可爱与低可爱度面部，以及某一面部类别内可爱与低可爱度面部的均值对应的6项参数。婴儿图式得分较高的面部，其面宽、额长与面长的比值以及眼宽与面宽的比值均高于婴儿图式得分较低的面部。我们通过简单回归分析，检验可爱与低可爱度婴儿面部在这6项参数上是否存在显著差异。在本研究样本中，白种人面部的面宽（p=0.018）与额长/面长比值（p=0.014）在可爱与低可爱度婴儿面部间呈现出预期方向的显著差异，其余参数的组间差异均不显著。婴儿图式的客观测量指标（参照Glocker等学者[2]）。
