“…We have reported in a previous paper results that show that the associative learning procedure used in the present study is also effective to modulate early perceptual processing of individual faces as shown by event-related potentials (Aguado et al, 2012). Taken together, what these results suggest is that positive and negative emotional expressions have power enough to modify the affective value of human faces and that this change is manifest at both central (brain responses) and peripheral levels (facial reactions).…”

“…Moreover, there is evidence suggesting that explicit instructions to evaluate an affective stimulus may dampen spontaneous, automatic affective responses (e.g., Lieberman, 2011) of which the EMG responses here studied are an example. In fact, a previous study by Aguado et al (2012) using a paradigm similar to that employed in the present experiment showed a different pattern of modulation of brain potentials to S1 neutral faces followed by emotional S2 faces and to those same S1 faces presented alone. Finally, S1 duration during the categorization trials was different for each participant and trial, as presentation of the stimulus was terminated by the categorization response.…”

Being able to extract socially relevant information from faces and to decode the meaning of facial expressions is crucial for a proper understanding of other´s feelings and intentions (e.g., Frith, 2007). The importance of our ability to read into other´s faces is underscored by studies describing deficits in the ability to extract social and affective information from faces in conditions such as autism and schizophrenia, where poor social adjustment is a prominent characteristic (e.g., Adolphs, Sears, & Piven, 2001;Kohler, Walker, Martin, Healey, & Moberg, 2010;Pelphrey et al., 2002). It has been repeatedly shown that viewing faces that show emotional expressions induces in the observer specific patterns of facial activity. While perception of happy or smiling faces tends to produce a response pattern characterized by increased activity of the zygomaticus major (ZM) muscle and decreased activity of the corrugator supercilii (CS), perception of angry faces usually leads to increased corrugator activity (e.g., Dimberg, 1982, Dimberg & Thunberg, 1998Dimberg & Ohman, 1996). These facial reactions are usually observed during the first second of exposure to an emotional expression and thus, have been called Rapid Facial Reactions (Moody, McIntosh, Mann, & Weisser, 2007). Although these reactions are usually sub-perceptual and are not visible to the naked eye, they can be detected by means of facial electromyography (EMG).Characterization of the mechanism underlying these reactions to facial expressions has been a matter of considerable debate. Some researchers have interpreted them in terms of social mimicry (Chartrand & Bargh, 1999; Lakin, Jefferis, Cheng, & Chartrand, 2003). By this account, perception of a specific facial expression automatically elicits a similar expression from the observer without any mediation by an emotional or evaluative process. For example, Chartrand and Bargh (1999) have proposed a perception-behavior link mechanism, by which perception of another´s behavior facilitates similar behavior in oneself. An alternative account considers facial reactions in the presence of emotional expressions as part of an affective reaction to the expressions themselves (Hess, Philippot, & Blairy, 1998;Moody et al., 2007). These reactions would thus be a consequence of a process involving affective evaluation and emotion recognition. Several pieces of evidence are consistent with this interpretation. Firstly, rapid facial reactions are Abstract. The possibility that facial expressions of emotion change the affective valence of faces through associative learning was explored using facial electromyography (EMG). In Experiment 1, EMG activity was regi...

“…On the other hand, multiple fast cortical pathways forming part of a feedforward and feedback mechanism consistute an equally plausible mechanism for rapid expression perception (Liu & Ioannides, 2010;Pessoa & Adolphs, 2010). (Aguado et al, 2012;Eger, Jedynak, Iwaki, & Skrandies, 2003;Schupp et al, 2004). On the other hand, modulations of the N170 faceresponsive component (120-200 ms) are consistently reported (see Hinojosa, Mercado, & Carreti e e, 2015 for a meta-analysis).…”

Recognizing emotion in faces is important in human interaction and survival, yet existing studies do not paint a consistent picture of the neural representation supporting this task. To address this, we collected magnetoencephalography (MEG) data while participants passively viewed happy, angry and neutral faces. Using time‐resolved decoding of sensor‐level data, we show that responses to angry faces can be discriminated from happy and neutral faces as early as 90 ms after stimulus onset and only 10 ms later than faces can be discriminated from scrambled stimuli, even in the absence of differences in evoked responses. Time‐resolved relevance patterns in source space track expression‐related information from the visual cortex (100 ms) to higher‐level temporal and frontal areas (200–500 ms). Together, our results point to a system optimised for rapid processing of emotional faces and preferentially tuned to threat, consistent with the important evolutionary role that such a system must have played in the development of human social interactions.

“…Una serie de estudios han encontrado que de forma paralela el reconocimiento de la expresión emocional del rostro puede modular el componente N170 tanto en amplitud como en latencia. Aguado et al (2012), compararon rostros con expresiones emocionales de ira y felicidad contra rostros neutros y encontraron mayor amplitud ante rostros de ira comparados con los rostros de felicidad y neutros. Baggott, Palermo y Fox (2011), detectaron mayor amplitud de rostros que expresaban miedo, ira y tristeza comparados con los rostros neutros.…”

Psychologia, 11(1), 39-48. ResumenLa discriminación de las emociones expresadas a nivel facial es importante para las relaciones sociales, la empatía y la interacción social. El objetivo de este estudio fue observar si existían diferencias en el procesamiento cortical ante dos emociones básicas, la ira y el miedo y definir si la percepción de la ira intensa genera una mayor modulación del componente N170 en amplitud y latencia en comparación con las imágenes de rostros con expresión de miedo intenso. Para este estudio se utilizó la técnica de potenciales evocados con un montaje de 32 canales. Se encontraron diferencias significativas en latencia para las imágenes de rostros que expresan ira intensa, comparados con la condición de imágenes de rostros de miedo intenso. Se encontraron diferencias tanto de la amplitud como de latencia ante imágenes de rostros de ira y miedo intensos en comparación con imágenes de rostros neutros. Palabras clave: emoción; P1; N170; rostros. AbstractThe discrimination of emotions expressed by the facial expressions is important for social relationships, empathy and social interactions. The main aim of this study was to study whether there were differences in the cortical processing to two basic emotions, anger and fear, and whether the perception of intense anger generates a higher modulation in amplitude and latency of the N170 component than intense fear. The technique used was event related potentials with a 32-channel montage. We found significant differences in the latency for images of faces expressing intense anger compared to the condition of images of faces of intense fear, as well as differences in amplitude in latency in response to the presentation of neutral faces in comparison to intense anger and fear.
