“…Exaggerated movements may also be important for communicating intentions during joint actions, in order to optimise the success of the action (Pezzulo et al, 2019;Vesper, Schmitz, Safra, Sebanz, & Knoblich, 2016) or to provide a social signal when used by the imitator (Krishnan-Barman & Hamilton, 2019).

“…Observing kinematics is also important when learning new actions as instructors often enhance or exaggerate features in a movement sequence in order to highlight the important elements to imitate (Brand, Baldwin, & Ashburn, 2002; McEllin, Knoblich, & Sebanz, 2018). Exaggerated movements may also be important for communicating intentions during joint actions, in order to optimise the success of the action (Pezzulo et al, 2019; Vesper, Schmitz, Safra, Sebanz, & Knoblich, 2016) or to provide a social signal when used by the imitator (Krishnan-Barman & Hamilton, 2019).

This study investigated whether reduced visual attention to an observed action might account for altered imitation in autistic adults. A total of 22 autistic and 22 non-autistic adults observed and then imitated videos of a hand producing sequences of movements that differed in vertical elevation while their hand and eye movements were recorded. Participants first performed a block of imitation trials with general instructions to imitate the action. They then performed a second block with explicit instructions to attend closely to the characteristics of the movement. Imitation was quantified according to how much participants modulated their movement between the different heights of the observed movements. In the general instruction condition, the autistic group modulated their movements significantly less compared to the non-autistic group. However, following instructions to attend to the movement, the autistic group showed equivalent imitation modulation to the non-autistic group. Eye movement recording showed that the autistic group spent significantly less time looking at the hand movement for both instruction conditions. These findings show that visual attention contributes to altered voluntary imitation in autistic individuals and have implications for therapies involving imitation as well as for autistic people’s ability to understand the actions of others.

“…In this case, the child has learned a novel social behaviour that can be used to affiliate with others. Despite the existence of ambiguous cases such as this, the distinction between instrumental and social has proved heuristically useful and references to social imitation have become increasingly prominent in the developmental literature over the last 10 years (Hoehl, Keupp, Schleihauf, McGuigan, Buttelmann, & Whiten, 2019;Krishnan-Barman & Hamilton, 2019;Nielsen, 2009;Over & Carpenter, 2009).…”

Imitation is a deeply social process. Here, I review evidence that children use imitation as a means by which to affiliate with others. For example, children imitate the actions of others more closely when they seek a positive social relationship with them and respond positively to being imitated. Furthermore, children infer something of the relationships between third parties by observing their imitative exchanges. Understanding the social nature of imitation requires exploring the nature of the social relationships between children and the individuals they imitate. Thus, in addition to discussing children's own goals in imitative situations, I review the social pressures children experience to imitate in particular ways, learning to conform to the conventions and rituals of their group. In the latter part of this article, I discuss the extent to which this perspective on imitation can help us to understand broader topics within social development, including the origins of human cultural differences. Expected final online publication date for the Annual Review of Developmental Psychology, Volume 2 is December 15, 2020.

We often perform actions while observed by others, yet the behavioural and neural signatures of audience effects remain understudied. Performing actions while being observed has been shown to result in more emphasized movements in musicians and dancers, as well as during communicative actions. Here, we investigate the behavioural and neural mechanisms of observed actions in relation to individual actions in isolation and interactive joint actions. Movement kinematics and EEG were recorded in 42 participants (21 pairs) during a mirror-game paradigm, while participants produced improvised movements alone, while observed by a partner, or by synchronizing movements with the partner. Participants produced largest movements when being observed, and observed actors and dyads in interaction produced slower and less variable movements in contrast with acting alone. On a neural level, we observed increased mu suppression during interaction, as well as to a lesser extent during observed actions, relative to individual actions. Moreover, we observed increased widespread functional brain connectivity during observed actions relative to both individual and interactive actions, suggesting increased intra-individual monitoring and action-perception integration as a result of audience effects. These results suggest that observed actors take observers into account in their action plans by increasing self-monitoring; on a behavioural level, observed actions are similar to emergent interactive actions, characterized by slower and more predictable movements.
