abstract = {Faces are encountered in highly diverse angles in real-world settings. Despite this considerable diversity, most individuals are able to easily recognize familiar faces. The vast majority of studies in the field of face recognition have nonetheless focused almost exclusively on frontal views of faces. Indeed, a number of authors have investigated the diagnostic facial features for the recognition of frontal views of faces previously encoded in this same view. However, the nature of the information useful for identity matching when the encoded face and test face differ in viewing angle remains mostly unexplored. The present study addresses this issue using individual differences and bubbles, a method that pinpoints the facial features effectively used in a visual categorization task. Our results indicate that the use of features located in the center of the face, the lower left portion of the nose area and the center of the mouth, are significantly associated with individual efficiency to generalize a face's identity across different viewpoints. However, as faces become more familiar, the reliance on this area decreases, while the diagnosticity of the eye region increases. This suggests that a certain distinction can be made between the visual mechanisms subtending viewpoint invariance and face recognition in the case of unfamiliar face identification. Our results further support the idea that the eye area may only come into play when the face stimulus is particularly familiar to the observer. © 2016 Elsevier Ltd.},

abstract = {Observation of others' actions induces a subliminal activation of motor pathways (motor resonance) that is mediated by the mirror neuron system and reflects the motor program encoding the observed action. Whether motor resonance represents the movements composing an action or also its motor intention remains of debate, as natural actions implicitly contain their motor intentions. Here, action and intention are dissociated using a natural and an impossible action with the same grasping intention: subjects observe an avatar grasping a ball using either a natural hand action ('palmar' finger flexion) or an impossible hand action ('dorsal' finger flexion). Motor-evoked potentials (MEPs), elicited by single transcranial magnetic stimulation of the hand area in the primary motor cortex, were used to measure the excitability modulation of motor pathways during observation of the two different hand actions. MEPs were recorded from the opponens pollicis (OP), abductor digiti minimi (ADM) and extensor carpi radialis (ECR) muscles. A significant MEP facilitation was found in the OP, during observation of the grasping phase of the natural action; MEPs in the ADM were facilitated during observation of the hand opening phase of the natural action and of both opening and grasping phases of the impossible action. MEPs in the ECR were not affected. As different resonant responses are elicited by the observation of the two different actions, despite their identical intention, we conclude that the mirror neuron system cannot utilize the observer's subliminal motor program in the primary motor cortex to encode action intentions. © 2011 Federation of European Neuroscience Societies and Blackwell Publishing Ltd.},
