“…Sociality is the tendency to involve oneself with others spontaneously ( De Jaegher et al, 2010 ; Amici and Widdig, 2019 ; Ichikawa et al, 2021 ); humans who interact based on sociality change their environments ( Sebanz et al, 2006 ). Social interactions are observed in living organisms including non-humans and serve as a foundation for various activities.…”

Humans often share roles and aim to achieve a group goal based on sociality, which is the tendency to spontaneously involve oneself with others. Cognitive science, psychology, and neuroscience studies suggest that in such planned coordination, adjusting one’s own actions based on other roles is crucial for high task performance. However, the mechanisms of complex and dynamically planned coordination, such as non-verbal group behavior with three or more members, remain to be fully investigated. This study introduced a coordinated drawing task in a triad, quantitatively analyzed non-verbal group behavior based on sharing heterogeneous roles, and investigated an important role. Participant triads engaged in the task repeatedly by operating reels to change thread tensions and moving a pen connected to the three threads to draw an equilateral triangle. Then, the three roles (pulling, relaxing, and adjusting) had to be shared. The pulling and relaxing roles served to move the pen as if an operator pulled it closer to the hand and to support the pen’s movement, respectively. However, these roles alone could not draw a side considering the task specification. The adjusting role needed to change the tension flexibly and maintain an overall balance. In the experiment, we measured the pen positions and tensions, and established statistical models to fit the analyzed data. The results estimated that the action in the adjusting role was related to the improved performance of faster drawing on a side. This role may moderately intervene in the actions by the other roles and fine-tune without disturbing the pen’s smooth movement while avoiding great pen deviation. Our findings may suggest the crucial role as a facilitator that handles resiliently in non-verbal coordinated behavior of a triad, and contribute to our understanding of social interactions.

“…While these studies effectively recapitulated many elements of the rodent literature, they require navigating a number of practical challenges such as the prolonged developmental timelines where sexual maturity is not reached until 3-4 years of age, where young adulthood is not reached until after 5 years of age, and where housing requirements present limitations regarding the assessment of social behaviors (15,17). Further, a comprehensive review of the literature by Amici et al (18) suggested that most developmental changes in macaque sociality occur between 2 and 3 years, making logistics and cost of colony management for experiments particularly challenging. In order to overcome this challenge, we aimed to develop and characterize a translationally relevant and practical non-human primate model of maternal immune activation using marmosets.…”

Advancing Autism Research From Mice to Marmosets: Behavioral Development of Offspring Following Prenatal Maternal Immune Activation

et al. 2021

Understanding the mechanism(s) by which maternal immune activation (MIA) during gestation may disrupt neurodevelopment and increase the susceptibility for disorders such as autism spectrum disorder (ASD) or schizophrenia is a critical step in the development of better treatments and preventive measures. A large body of literature has investigated the pathophysiology of MIA in rodents. However, a translatability gap plagues pre-clinical research of complex behavioral/developmental diseases and those diseases requiring clinical diagnosis, such as ASD. While ideal for their genetic flexibility, vast reagent toolkit, and practicality, rodent models often lack important elements of ethological validity. Hence, our study aimed to develop and characterize the prenatal MIA model in marmosets. Here, we adapted the well-characterized murine maternal immune activation model. Pregnant dams were administered 5 mg/kg poly-L-lysine stabilized polyinosinic-polycytidylic acid (Poly ICLC) subcutaneously three times during gestation (gestational day 63, 65, and 67). Dams were allowed to deliver naturally with no further experimental treatments. After parturition, offspring were screened for general health and vigor, and individual assessment of communication development and social behavior was measured during neonatal or adolescent periods. Similar to rodent models, offspring subjected to MIA exhibited a disruption in patterns of communication during early development. Assessment of social behavior in a marmoset-modified 3-chamber test at 3 and 9 months of age revealed alterations in social behavior that, in some instances, was sex-dependent. Together, our data indicate that marmosets are an excellent non-human primate model for investigating the neurodevelopmental and behavioral consequences of exposure to prenatal challenges, like MIA. Additional studies are necessary to more completely characterize the effect of prenatal inflammation on marmoset development and explore therapeutic intervention strategies that may be applicable in a clinical setting.

“…It seems undoubted that to be social comes first, starting from the long background of ape social worlds. The common background of deep sociality in the great apes suggests from the genetic and fossil evidence that this phenomenon goes back some 20 million years (Amici & Widdig, 2019; Dunbar & Shultz, 2007; Shultz & Dunbar, 2014; Simons, 2002). It cannot therefore explain everything new in Homo , except through changes in the nature and levels of sociality.…”

Deep structure in the Acheulean adaptation: technology, sociality and aesthetic emergence

This article considers the adaptive setting and probable origins of human aesthetic capabilities, using evidence of the Acheulean tradition in the last million years, and highlighting the importance of the preceding and enveloping social and technological contexts. Acheulean bifaces, made from about 1.75 to 0.1 Ma, often with an appearance of symmetry, give windows on crucial interlocking aspects of human intellectual evolution. These have been seen as the domains of technology, sociality and aesthetics, following Leroi-Gourhan, or in near-equivalence the ‘technological’, ‘sociological’ and ‘ideological/philosophical’ of L.A. White. These domains can be analysed to have a reality, in the sense that social worlds of the apes far antedate technology, which in turn is generally taken to be far older than a sense of aesthetic appreciation. The bifaces are helpful in illustrating early developments because they can be made only through bringing together a set of concepts linking form, function and technology of manufacture, in a recurring ‘deep structure’. As there are at least 6 to 12 necessary concepts, perhaps significantly more, the artefacts are essentially multivariable or multivariate. They thus impose high cognitive requirements in manufacture, pressing towards effective sequencing of steps so that not too many variables will be involved simultaneously. Support of such a knowledge base has social requirements of shared or collective intention. Biomechanical and functional necessities also exert pressures on concepts: rules maintained by all these requirements entail a notion of ‘appropriateness’ or ‘rightness’ that may have been a prime factor in driving evolution of a sense of aesthetics and even the shaping of moral feelings. As the rules are variably expressed through time and space in the Acheulean, some of the best information comes from seeing how far particular variables are ‘locked’ in relationships which recur to give the impression of deep structure.
