“…This is consistent with research on adults, which suggests that priming effects dissipate rapidly (e.g., ). Furthermore, ERP components differentiate congruent and incongruent reaching and pointing at ~400 ms after stimulus onset . Taken together, these observations suggest that the time needed for infants to identify the central cue and shift attention to the side is somewhere between 100 and 500 ms.…”

“…In electroencephalography studies, the priming effect, with respect to gaze, is indexed by temporal parietal event‐related potential (ERP) components N290 and P400, both known to index social processing in early infancy . The observation of static hands depicting a grasping or pointing gesture yielded similar findings . With respect to grasping, the P400 component differentiates congruent and incongruent trials for 5‐ and 6‐month‐olds who are proficient at grasping, but not 4‐ or 5‐month‐olds who are less proficient at grasping.…”

“…For example, movement per se is the determining factor underlying priming of gaze direction in newborns (18), and a moving hand primed pointing gestures for 4½-month-olds (13). ERP correlates of priming from static hands emerge later, at 5 months for grasping and at 9 months for pointing (15,16).…”

In this article, we review recent evidence of infants' early competence in perceiving and interpreting the actions of others. We present a theoretical model that decomposes the timeline of action perception into a series of distinct processes that occur in a particular order. Once an agent is detected, covert attention can be allocated to the future state of the agent (priming), which may lead to overt gaze shifts that predict goals (prediction). Once these goals are achieved, the consequence of the agents' actions and the manner in which the actions were performed can be evaluated (evaluation). We propose that all of these processes have unique requirements, both in terms of timing and cognitive resources. To understand more fully the rich social world of infants, we need to pay more attention to the temporal structure of social perception and ask what information is available to infants and how this changes over time.

“…Although the grasp itself is performed by infants from 6 months (Bakker, Daum, Handl, & Gredeb€ ack, 2014), any useful mirroring response to the critical images would need to incorporate the hand position relative to the functional tool-end.

When learning about the functions of novel tools, it is possible that infants may use associative and motoric processes. This study investigated the ability of 16-month-olds to associate the orientation in which an actor held a dual-function tool with the actor's prior demonstrated interest in one of two target objects, and their use of the tool on that target. The actors' hand posture did not differ between conditions. The infants were shown stimuli in which two actors acted upon novel objects with a novel tool, each actor employing a different function of the tool. Using an eye-tracker, infants' looking time at images depicting the actors holding the tool in an orientation congruent or incongruent with the actor's goal was measured. Infants preferred to look at the specific part of the tool that was incongruent with the actor's goal. Results show that the association formed involves the specific part of the tool, the actor, and the object the actor acted upon, but not the orientation of the tool. The capacity to form such associations is demonstrated in this study in the absence of motor information that would allow 16-month-olds to generate a specific representation of how the tool should be held for each action via mirroring processes.

We performed an Independent Component Analysis (ICA) to identify and remove signal artifacts, considering time, topographic, and spectral distribution of the component.…”

Throughout life, actions and language are inherent to social interactions. A long-standing research question in cognitive neuroscience concerns the interrelation between verbal and non-verbal forms of social interactions, that is, language and action. Perceiving how actions are performed and why they are performed in a certain way is crucial for the observer to anticipate the actor's goal and to prepare an appropriate response. It is suggested that predicting upcoming events in a given action sequence can be compared to the way we process the language information flow. Goal-directed actions can be sequenced in small units, which are organized according to a hierarchical plan, resembling the hierarchical organization of language. Research on adults suggests that manipulating the action structure (i.e., action syntax) leads to analogous cortical signatures as a similar manipulation of a sentence structure (i.e., language syntax). Whereas in adults language and action knowledge are based on life-time experience, in infants both domains are still developing. The current study examined the neural processing of structural violations of observed goal-directed action sequences in infants at 6-7 months, using event-related potentials (ERPs). Results showed that a structural violation of the action sequence elicited bilateral frontal positivity effects. This suggests that infants capture structural regularities, and it adds a crucial element to the understanding of general syntactic regularities and their violation from an ontogenetic perspective.
