Ery related and are usually not shown. The frequency axis islog scaled. The zero point on the time axis indicates the onset of the action movies. Shortly right after the onset from the stimuli,there was a rise in theta energy ( Hz),followed by a reduction in alpha energy (see also Figure.oscillations at channels F and F for completeness.

These MVPA results were hence in line with all the final results of the traditional analyses.DISCUSSIONWe investigated how the sensorimotor EEG mu rhythm that is considered to index human MNS activity,and the frontal theta activity that is definitely implicated in memory processes are modulated by the human likeness with the agent getting observed. Participantsviewed three agents,a Human,in addition to a stateoftheart robot in two diverse appearances (as an Android in addition to a Robot) performing the same recognizable actions. The Human had biological motion and appearance,whereas the Android had biological look and mechanical motion,as well as the Robot had mechanical motion and mechanical look (Figure. We hypothesized that any modulations on the oscillations by sensory attributes of the stimuli will be revealed as substantial differences involving the experimental conditions,according to the seen agents’ differing appearance and motion qualities. Particularly if these dependent measures are sensitive to the movement kinematics on the observed actor,then we would expect the Human situation to be distinguished in the other folks. If they’re sensitive to the appearance,then the Robot will be distinguished from the other agents,or there would be a degree of activity that corresponds for the degree of human likeness of the look with the agents.

The Robot situation led to significantly elevated theta power in comparison towards the Android and Human circumstances (p’s see Results).are sensitive to the congruence of the movement dynamics and look,then Android will be distinguished in the other agents because this condition functions a humanlike appearance as well as nonhuman motion dynamics,whereas the other agents feature congruent look and motion (each biological,or both mechanical). If on the other hand these dependent measures reflect higherlevel processing associated with the meaning from the actions and will not be sensitive for the visual properties of the stimuli,then the agents may well not differ from each other considering the fact that they all carry out the pretty similar actions.Mu OSCILLATIONSWe showed that the observation in the human agent as well as both of the robot agents resulted in robust and significant attenuations within the power of mu oscillations over the frequently reported sensorimotor places. The magnitude on the attenuations was equivalent for all agents. This replicates and extends a previous mu suppres.
