“…The mean peak in the live group was 8.1 Hz (SD = 0.75) and 8.1 Hz (SD = 0.60) for the video group. This is in agreement with previous studies on mu/alpha rhythm frequencies in infants (Marshall et al, 2002;Stroganova et al, 1999). A ratio was used to control for the individual variability in absolute EEG power due to individual differences such as electrode impedance or scalp thickness.…”

We thank the participating day-care centres and organizations, all the participating children and their parents.The procedure used in the current study was approved by the ethical committee of Ghent University. Informed consent was obtained from all subjects.The authors declare that they have no conflict of interest.Keywords : neural mirroring, mu suppression, video, infants, EEG, imitation 2 Highlights:• We measured significant EEG mu suppression during the observation and imitation of live goal-directed and mimicked actions in 18-to 36-months olds.• In the video setting, where the goal-directed and mimicked actions were presented on video, no mu suppression was found during the observation conditions and less mu suppression was found during the action imitation condition compared to the live setting.• The findings indicate the use of live actions in the design of paradigms investigating neural mirroring in infants. 3 AbstractObjective: Previous infant studies investigated neural mirroring during the observation of live or video actions. However, both methods have their (dis)advantages and studies using one of these methods are not always directly comparable. Therefore, the present study directly compared neural mirroring activity in a video setting with a live setting in infants between 18 and 36 months old.Methods: Central mu rhythm suppression was measured through EEG recordings during the observation and imitation of the same goal-directed and mimicked actions presented either on video or live.Results: Results revealed significant mu suppression during action imitation in both settings but stronger mu suppression was observed in the live setting during this condition. Significant mu suppression during the observation of goal-directed actions and mimicked actions was only observed in the live setting. Conclusion:This study revealed a different influence of video and live actions on neural mirroring activity in infants.Significance: It is recommended to use live actions to investigate neural mirroring in young children.4

“…This ERP component can be observed not only after the commission of errors, but also in response to perceived errors or even in the absence of awareness about perceiving the error [48][49][50][51][52][53][54][55]. As we previously mentioned, a fronto-central negative component comparable to the adults' ERN is also observed in infants and toddlers [21,22,56,57].…”

“…Frontal theta activation in young children may thus be an important mechanism promoting the development of optimal structural connections between regions within the EA network. Indeed, there is an increase in theta power during infancy that might underlie the development of cortical pathways associated with the shift from the primarily exogenous to the more internally controlled attention observed by the end of the first year of life [55,56]. As mentioned earlier, a recent study investigating neural mechanisms of error detection in toddlers found a significant increase of frontal theta power associated with the processing of errors, suggesting that evoked theta power may also serve as a neural marker of early EA skills [27].…”

Executive attention (EA) encompasses a variety of attention mechanisms implicated in the control of thoughts and behavior. The emergence of EA skills depends on the maturation of frontal brain structures. Evidence in the past years has shown that frontal brain structures related to EA are already functional in the first months of life and first signs of EA can be observed by the second half of the first year of life. Given the importance of EA to a wide range of developmental outcomes (e.g. academic and professional outcomes, socialization, psychological wellbeing, etc.), understanding early stages of development is of great interest for the promotion of EA and the prevention of EA-related deficits over the course of development. Despite its relevance, relatively little is known about the development of EA before the preschool years. This paper aims at providing a selective review of the existing literature about the early development of EA. We present the principal measures of EA for infants and toddlers available to date. We also review main findings on behavioral as well as brain mechanisms of EA in infancy and toddlerhood. Finally, we summarize research on early indicators of EA and its implication for the early detection of some developmental disorders.

Studying human infants will increase our understanding of the nature, origins and function of neural mirroring mechanisms. Human infants are prolific imitators. Infant imitation indicates observation-execution linkages in the brain prior to language and protracted learning. Investigations of neural aspects of these linkages in human infants have focused on the sensorimotor mu rhythm in the electroencephalogram, which occurs in the alpha frequency range over central electrode sites. Recent results show that the infant mu rhythm is desynchronized during action execution as well as action observation. Current work is elucidating properties of the infant mu rhythm and how it may relate to prelinguistic action processing and social understanding. Here, we consider this neuroscience research in relation to developmental psychological theory, particularly the 'Like-Me' framework, which holds that one of the chief cognitive tasks of the human infant is to map the similarity between self and other. We elucidate the value of integrating neuroscience findings with behavioural studies of infant imitation, and the reciprocal benefit of examining mirroring mechanisms from an ontogenetic perspective.
