“…Indeed, in line with past research [63,64], the majority of participants judged the profile at the top of the stimulus sheet as more attractive than the profile at the bottom. Although previous studies related the preference for left-or right-facing profiles to different variables such as cultural and demographic factors [69,72,78,79], reading/writing habits [80], handedness and other motor biases [69,80,81] (see also [82]), poser's sex [73,77], emotional expression [54,72,83] and trustworthiness [84], perceived person-related traits [74] and political orientation [85], and selfie-taking styles (i.e., with the camera pointing toward the selfie-taker vs. toward their reflection in a mirror [66,71]), no study has ever examined its possible relationship with cradling-side preferences. However, to be honest, such a link (at least in terms of the cradled individual's point of view) had already been proposed-although on a purely speculative basis-by McManus and Humphrey [73] and Conesa et al [68,86], who hypothesized that the preference for left-facing profiles might arise from the LCB during a critical period for the development of vision (i.e., the first four months of life), given that when infants are held on the left arm of mothers, they are exposed to the left profile of the mother's face.…”
