“…This may also be relevant to studies which have found that the social relationship between the observer and the performer may influence mirror neuron activity (Liew, Han, & Aziz-Zadeh, 2010). The reward value attributed to the observed action can depend upon the relationship between confederates in a social interaction, such as that demonstrated by in-group vs. out-group differences (Gudykunst et al, 1992;Sobhani, Fox, Kaplan & Aziz-Zadeh, 2012), and competitive vs. cooperative scenarios (Koban, Pourtois, Vocat, & Vuilleumier, 2010). Different social contexts will induce different degrees of reward associated with others' actions, which could depend upon a wide variety of personal and interpersonal motivational factors.…”

Modulation of motor cortex activity when observing rewarding and punishing actions

a b s t r a c tInterpreting others' actions is essential for understanding the intentions and goals in social interactions. Activity in the motor cortex is evoked when we see another person performing actions, which can also be influenced by the intentions and context of the observed action. No study has directly explored the influence of reward and punishment on motor cortex activity when observing others' actions, which is likely to have substantial relevance in different social contexts. In this experiment, EEG was recorded while participants watched movie clips of a person performing actions that led to a monetary reward, loss or no change for the observer. Using the EEG mu rhythm as an index of motor resonance, our results demonstrate that observation of rewarding actions produce significantly greater motor cortex activity than punishing or neutral actions, with punishing actions producing greater activity than neutral ones. In addition, the dynamic change in the mu rhythm over sensorimotor cortex is modulated by reward and punishment, with punishing actions producing a prolonged suppression. These findings demonstrate that the associated reward value of an observed action may be crucial in determining the strength of the representation of the action in the observer's brain. Consequently, reward and punishment is likely to drive observational learning through changes in the action observation network, and may also influence how we interpret, understand, engage in and empathize with others' actions in social interaction.

“…Broadly speaking this study supports recent evidence showing that activation in the AON, and particularly the dPMC, is modulated by the social context in which actions are observed. Activity in the AON has been found to differ depending on whether the action is performed by an in‐group or out group member (Molenberghs et al ., ), or whether the actions are by a member of a liked or disliked group (Sobhani et al ., ). However, in both previous studies the direction of the modulation was the reverse of that in this study with greater activation for the actions of in‐group members or liked others.…”

“…Molenberghs et al (2013) found that observing a stranger who had randomly been assigned to the same team as the participant led to a preferential activation of the IPL, compared to observing someone assigned to another team.

Our interactions with other people - and our processing of their actions - are shaped by their reputation. Research has identified an Action Observation Network (AON) which is engaged when observing other people's actions. Yet, little is known about how the processing of others' actions is influenced by another's reputation. Is the response of the AON modulated by the reputation of the actor? We developed a variant of the ultimatum game in which participants watched either the visible or occluded actions of two 'proposers'. These actions were tied to decisions of how to split a pot of money although the proposers' decisions on each trial were not known to participants when observing the actions. One proposer made fair offers on the majority of trials, establishing a positive reputation, whereas the other made predominantly, unfair offers resulting in a negative reputation. We found significant activations in two regions of the left dorsal premotor cortex (dPMC). The first of these showed a main effect of reputation with greater activation for the negative reputation proposer than the positive reputation proposer. Furthermore individual differences in trust ratings of the two proposers covaried with activation in the right primary motor cortex (M1). The second showed an interaction between visibility and reputation driven by a greater effect of reputation when participants were observing an occluded action. Our findings show that the processing of others' actions in the AON is modulated by an actor's reputation, and suggest a predictive role for the PMC during action observation.

“…For example, early motor system resonance is lower while preparing to counter-imitate than to imitate (Cross & Iacoboni 2014), can be modulated by likeability of the actor (Sobhani et al 2012), and is reduced when the participant is treated unfairly by the actor (Aragón et al 2013). Nonconscious mimicry is heightened when the subject desires to desires social connection or rapport, suggesting that social goals modulate simulation (Lakin and Chartrand 2003; Aragón et al 2013).…”

Common coding and dynamic interactions between observed, imagined, and experienced motor and somatosensory activity

Motor imagery and perception- considered generally as forms of motor simulation- share overlapping neural representations with motor production. While much research has focused on the extent of this “common coding,” less attention has been paid to how these overlapping representations interact. How do imagined, observed, or produced actions influence one another, and how do we maintain control over our perception and behavior? In the first part of this review we describe interactions between motor production and motor simulation, and explore apparent regulatory mechanisms that balance these processes. Next, we consider the somatosensory system. Numerous studies now support a “sensory mirror system” comprised of neural representations activated by either afferent sensation or vicarious sensation. In the second part of this review we summarize evidence for shared representations of sensation and sensory simulation (including imagery and observed sensation), and suggest that similar interactions and regulation of simulation occur in the somatosensory domain as in the motor domain. We suggest that both motor and somatosensory simulations are flexibly regulated to support simulations congruent with our sensorimotor experience and goals and suppress or separate the influence of those that are not. These regulatory mechanisms are frequently revealed by cases of brain injury but can also be employed to facilitate sensorimotor rehabilitation.
