Procesamiento emocional de las expresiones faciales en el envejecimiento normal y patológico

Emotional processing in patients with mild cognitive impairment: The influence of the valence and intensity of emotional stimuli

“…Individuals with MCI presented a floor effect with regards the emotion of disgust, whereby the intensity did not influence its detection and such individuals had remarkable problems in identifying this emotion [45,46], even at strong intensities. In these individuals, intensity also had a weak influence on the emotions of surprise and sadness, yet it had a very clear influence on fear and anger, in accordance with previous studies [35,36]. Thus, intensity seems to play a key role in identifying the emotions as it provides information relevant to the subject, although its contribution varies in function of the different type of emotion.…”

“…This is especially relevant from the theoretical point of view, as it confirms that attentional resources are crucial in emotional processing, and consequently, that they control such processing [35,36]. The attentional demands for each expression appear to differ, with the expression of happiness, surprise and sadness requiring the least attentional resources, while fear and disgust use more resources.…”

“…From this point of view, the worse outcomes are explained to some extent by the loss of cognitive resources characteristic of aging [34] and they are more evident in cases of dementia [23]. Along similar lines, several studies indicate that deficits in processing EFEs may also depend on the type of mental operation required to complete the task: identification, and matching [35,36]. Different tasks are employed in the recognition of facial expressions and they require various cognitive resources, which imply that the specific requirements of each task will determine, in part, the results.…”

The role of interference in identification of emotional facial expressions in normal ageing and dementia

“…Taken together, these data suggest that a correct identification of EFEs necessarily requires the involvement of cognitive resources. We (García-Rodríguez, Ballesteros, Rodríguez, Reales, & Fusari, 2006;García-Rodríguez, Fusari, & Ellgring, 2008), as well as others (Gazzaley & D'Esposito, 2007;Pessoa et al, 2002;Storbeck & Clore, 2007) suggest that EFEs should be studied using cognitive paradigms to understand the mental processes underlying emotional identification. Traditional behaviour studies did not regard emotion as a cognitive process.…”

Reconocimiento de Expresiones Faciales Emocionales. Diferencias en el Desarrollo

“…En este marco, el reconocimiento de emociones faciales es entendido como el proceso por el cual se perciben y analizan los rasgos faciales para la identificación del estado emocional que los mismos denotan (Adolphs, 2002). El mismo aporta información adicional para la interpretación de los mensajes y las acciones de los demás, desempeñando un papel central en la regulación de la conducta social como componente de la interacción interpersonal (García-Rodríguez et al, 2008). Esta línea de investigación estuvo principalmente orientada al estudio de las expresiones faciales de las emociones básicas, entendiendo a estas como estados somáticos ligados a conductas fundamentales para la supervivencia, en tanto acciones que se expresan en el rostro, la voz o en conductas específicas tendientes a mantener la homeostasis (Damasio, 2005;Miguel, 2015).…”
