“…In contrast, core autism symptoms explained most of the variance in extreme leftward patterns. Importantly, language is lateralized to the left hemisphere in most individuals ( Hirnstein et al, 2013 ), while comparative research points toward right-hemispheric dominance for social processing ( Karenina and Giljov, 2018 ). Specifically, Karenina and Giljov (2018) suggested the existence of a right-hemispheric dominance for social processing through analysis of asymmetries in mother-offspring positioning in different animal species.…”

Investigating the link between functional hemispheric asymmetries and mother-infant positioning during interactions has a long tradition in human laterality research ( Bourne and Todd, 2004 ) and is still popular today ( Packheiser et al, 2019 , 2020 ; Malatesta et al, 2020b ).…”

Recent large-scale neuroimaging studies suggest that most parts of the human brain show structural differences between the left and the right hemisphere. Such structural hemispheric asymmetries have been reported for both cortical and subcortical structures. Interestingly, many neurodevelopmental and psychiatric disorders have been associated with altered functional hemispheric asymmetries. However, findings concerning the relation between structural hemispheric asymmetries and disorders have largely been inconsistent, both within specific disorders as well as between disorders. In the present review, we compare structural asymmetries from a clinical neuroscience perspective across different disorders. We focus especially on recent large-scale neuroimaging studies, to concentrate on replicable effects. With the notable exception of major depressive disorder, all reviewed disorders were associated with distinct patterns of alterations in structural hemispheric asymmetries. While autism spectrum disorder was associated with altered structural hemispheric asymmetries in a broader range of brain areas, most other disorders were linked to more specific alterations in brain areas related to cognitive functions that have been associated with the symptomology of these disorders. The implications of these findings are highlighted in the context of transdiagnostic approaches to psychopathology.

“…Moreover, Huggenberger et al [26] found that, compared with nulliparous non-left-cradling women, left-cradling ones exhibited a lower response bias to erroneously judge neutral baby faces presented in the left visual hemifield as emotional (and vice versa for stimuli presented in the right visual hemifield), concluding that women's cradling side preferences might have evolved for saving cognitive resources when monitoring emotional signals from baby faces. Although the cradling literature is rich of several different assessment methodologies and is not yet able to provide a congruent and conclusive explanatory model of the LCB, it is plausible that-as suggested by recent comparative research [27,28]-such an asymmetry stems from deeply rooted preferences in mammalian mothers to choose a posture fostering the transmission of emotional information via their right cerebral hemisphere in order to recognize more efficiently potential cues of distress in the infant (see [29] for consistent findings and considerations).…”

Keep a Left Profile, Baby! The Left-Cradling Bias Is Associated with a Preference for Left-Facing Profiles of Human Babies

2020

The left-cradling bias (LCB) refers to the (typically female) preference to hold an infant on the left side of one’s own body. Among the three main accounts proposed for such a phenomenon, namely the “handedness”, “heartbeat” and “hemispheric asymmetry” hypotheses, the latter has met with the greatest empirical success. Accordingly, the LCB would facilitate the communication of socio-emotional information through the right hemisphere of both the cradled and the cradling individual, and should emerge mainly in face-to-face interactions. In this regard, it should be noticed that when the infant’s body is oriented toward the cradler, the left or right side of their face is relatively more visible to left- and right-cradlers, respectively. Therefore, we hypothesized that the LCB might also be associated with a preference for left-facing profiles (i.e., those showing the left, and more expressive, hemiface/cheek) of human babies. In order to test our hypothesis, we assessed the cradling-side preferences of female participants, as well as their preference for the left- or right-facing profile of a human infant depicted in a drawing. Left-cradlers exhibited a significantly larger preference for the left-facing version of the drawing compared with right-cradlers, a finding further corroborating the right-hemisphere hypothesis.

“…To assess the presence of biases in side and sagittal preference at the group level, we used the one sample t-tests on the SI and the TI [ 18 ]. To verify the consistency of side/sagittal preference among different social interactions we used the one-way ANOVA for independent samples with a Tukey HSD test serving as the post hoc test.…”

“…Within social interactions, in wild chimpanzees the nature of social relationships influenced laterality, with a prevalence of right-handed gestures in context requiring efficient communication [ 17 ]. In the context of mother–infant interactions, different studies on non-human primates reported a left-side bias in both maternal cradling and nipple preference of the infants (for review see [ 18 , 19 ]). Regarding social dynamics of Old-World monkeys, gelada baboons ( Theropithecus gelada ) showed a preference for the left visual field during agonistic interactions [ 20 ].…”

Is There a “Right” Side of Communicating Friendship? Lateralization of Social Interactions in Zoo Barbary macaques (Macaca sylvanus)

Social laterality in non-human primates has started to attract attention in recent years. The positioning of individuals during social interactions could possibly suggest the nature of a relationship and the social ranking of the subjects involved. The subjects of the present study were 12 adult Barbary macaques (Macaca sylvanus) housed in a zoological garden. We carried out fourteen 210-min video-recorded sessions and we used a focal animal sampling method to collect the position of the subjects during different social interactions. Data on the position of each macaque during three types of social interactions were collected (approach, proximity and affiliative contacts). Moreover, we focused on the outcomes of dyadic agonistic encounters to build the hierarchy of the colony. For each social interaction, two conditions were considered: the side preference (being kept on the left or on the right) and the sagittal preference (being kept in front or on the rear). Bouts of preference of different positions were collected for different social interactions (approach, proximity and contacts). No group-level side preferences were found for any social interaction, suggesting that both hemispheres might be complemental and balance each other during intraspecific communication. For the sagittal preference, we found a group-level bias for proximity, with macaques being kept in front rather than on the rear by close conspecifics. This might be due to the need to detect emotions and intentions of conspecifics. Moreover, high-ranking individuals are kept more frontally than on the rear when in proximity with other macaques. More studies are needed to better investigate social laterality, possibly distinguishing more categories of social interaction, and detecting other variables that might influence the positioning preferences.
