“…The LPP, a relative positivity between around 400 to 600 ms at centro-parietal sites, has likewise been found to be enhanced for emotional compared to neutral stimuli and is viewed as an index of more elaborate processing and higher-order evaluation of affective information (e.g., Schacht & Sommer, 2009; Schupp et al, 2004; for a review of EPN and LPP effects for emotional faces, see Schindler & Bublatzky, 2020). In addition to these two frequently observed effects, which are regarded as markers of the processing of emotional stimuli in general, research on the effects of affective information on face perception has also focused on the earlier N170 component (for a review, see Schindler et al, 2023). The N170, which is observable as a negative deflection between approximately 130 and 200 ms over occipitotemporal electrode sites, is regarded as a marker of the structural encoding and configural processing of facial information (Bentin et al, 1996; Eimer et al, 2010; Hinojosa et al, 2015).…”

While evidence across different studies displays considerable variance, findings overall show increased N170 amplitudes for faces of emotional relevance, indicating an early prioritized processing of configural facial information (Schindler et al, 2023).…”

Not all visual stimuli processed by the brain reach the level of conscious perception. Previous research has shown that the emotional value of a stimulus is one of the factors that can affect whether it is consciously perceived. Here, we investigated whether social-affective knowledge influences a face's chance to reach visual consciousness. Furthermore, we took into account the impact of facial appearance. Faces differing in facial trustworthiness (i.e., being perceived as more or less trustworthy based on appearance) were associated with neutral or negative socially relevant information. Subsequently, an attentional blink task was administered to examine whether the manipulated factors affect the faces' chance to reach visual consciousness under conditions of reduced attentional resources. Participants showed enhanced detection of faces associated with negative as compared to neutral social information. In event-related potentials (ERPs), this was accompanied by effects in the time range of the early posterior negativity (EPN) component. These findings indicate that social-affective person knowledge is processed already before or during attentional selection and can affect which faces are prioritized for access to visual consciousness. In contrast, no clear evidence for an impact of facial trustworthiness during the attentional blink was found. This study was pre-registered using the Open Science Framework (OSF).

“…En segundo lugar, la fase N170 posterior refleja un aumento de las activaciones tempranas en áreas visuales secundarias y asociativas relativas al contenido específico del estímulo. Es una modulación negativa del ERP entre 120 y 190 ms, que es mayor para las caras en comparación con varias clases de objetos (Schindler et al, 2023). A nivel de literatura, los primeros estudios concluyeron que era insensible a la expresión facial, no obstante, existe evidencia heterogénea al respecto dado que se descubrió que el N170 es sensible a las expresiones faciales (Hinojosa et al, 2015).…”

Internal body processes give rise to signals that are perceived and integrated by the brain, generating an instantaneous monitoring of the internal body state in a process called interoception, differentiated from attention to external signals (exteroception). The overall objective of the present study was to characterize at the physiological and behavioral level the relationship between interoceptive attention and emotional recognition. Behavioral analyses of the first experiment indicate that the presentation of emotional stimuli did not have an enhancing effect on performance in interoceptive recognition tasks. Although interoceptive processes are related to emotional processes, the relevant dynamic is one of attentional compensation. In this sense, based on this idea the behavioral results of the second experiment suggest that the differences in performance on emotional recognition tasks according to attentional focus were specific to the emotional recognition task on faces. Whereas the EEG data distinguished between interoceptive and exteroceptive attentional processes, particularly during the early phase (P100) only for the emotional face recognition tasks. The group without attentional focus demonstrated greater accuracy in their responses compared to the group with exteroceptive focus at the behavioral level. In conclusion, the interrelationship between emotion and interoception is influenced by attention, especially during the initial phases of perceptual processing, as evidenced by the EEG findings. An unbalanced allocation of attentional resources could lead to emotional dysregulations and perceptual errors, contributing to physical symptoms associated with perceptual noise or could decrease attention to introspective emotions and affect empathy towards others. A new model is presented that illustrates the linking process between the external representation of salient stimuli and the internal state, highlighting the importance of attention in this connection.
