“…In these particular conditions, faces used as neutral could be further processed despite the fact that they were contrasted with well-characterized expressions of emotions (Marinkovic & Halgren, 1998). This way of thinking also provides an account for the absence of such SPW differences found by González-Garrido, Ramos-Loyo, López-Franco and Gómez-Velázquez (2009) and by Marinkovic and Halgren (1998) when the attention of the participant was diverted from facial expressions (by focusing on the size of the ears and by doing a recognition memory task, respectively). There, emotions were not task-relevant.…”

Faces of unknown persons are processed to infer the intentions of these persons not only when they depict full-blown emotions, but also at rest, or when these faces do not signal any strong feelings. We explored the brain processes involved in these inferences to test whether they are similar to those found when judging full-blown emotions. We recorded the event-related brain potentials (ERPs) elicited by faces of unknown persons who, when they were photographed, were not asked to adopt any particular expression. During the ERP recording, participants had to decide whether each face appeared to be that of a positively, negatively, ambiguously, or neutrally intentioned person. The early posterior negativity, the EPN, was found smaller for neutrally categorized faces than for the other faces, suggesting that the automatic processes it indexes are similar to those evoked by full-blown expressions and thus that these processes might be involved in the decoding of intentions. In contrast, in the same 200-400 ms time window, ERPs were not more negative at anterior sites for neutrally intentioned faces. Second, the peaks of the late positive potentials (LPPs) maximal at parietal sites around 700 ms postonset were not significantly smaller for neutrally intentioned faces. Third, the slow positive waves that followed the LPP were larger for faces that took more time to categorize, that is, for ambiguously intentioned faces. These three series of unexpected results may indicate processes similar to those triggered by full-blown emotions studies, but they question the characteristics of these processes.

Implicit emotion regulation defined as goal-driven processes modulates emotion experiences and responses automatically without awareness. However, the temporal course of implicit emotion regulation is not clear. To address these issues, we adopted a new Priming-identify task (PI task) to manipulate implicit emotion regulation directly and observed the changes of early (N170), middle (early posterior negativity, EPN), and late event-related potentials (ERPs) components (late positivity potentials, LPP) under the different implicit emotion regulation conditions. The behavioral results indicated that the PI task manipulated subjective emotion experience effectively by priming emotion regulation goals. The ERP results found that implicit emotion regulation induced more negative N170 without altering the EPN and the LPP amplitudes, indicating that implicit emotion regulation occured automatically in the early perceptual stage not in the late selective attention stage of emotion processing. The correlation analysis also found the enlarged N170 was associated with decreased negative emotion subjective rating, suggesting that the N170 was probably an effective index of implicit emotion regulation. These observations imply that implicit emotion regulation probabbly occurs in the early stage of emotion processing automatically without consciousness.

“…Numerous studies have addressed the effects of affective stimuli on cognitive processes such as attention, memory and executive functions [18][19][20][21][22][23][24][25][26][27]. Actually, it seems that the appearance of an emotional stimulus might interfere with the processing of other stimuli emerging in the Functional Brain Mapping and the Endeavor to Understand the Working Brain temporal vicinity, basically due to the fact that stimuli with emotional content attract attentional resources because of their adaptive relevance [28][29][30][31].…”

IntroductionFor centuries, philosophers and neuroscientists have questioned whether the use of language and the ability to solve complex problems are related and, if so, what the nature of the relationship between language and thought is. Most of the attention -and controversy -have been focused on the claim that the structure of language shapes non-linguistic thinking socalled linguistic relativity.Human intelligence directly derives from brain activity and it is closely linked to the natural languages that humans speak [ ]. The Language, this complex system of sound-meaning connections, not only provides a comprehensive description of the world, but its acquisition is one of the most fundamental human traits, and it is obviously the brain that undergoes the developmental changes."rain development seems to be non-linear, with sensitive periods of time in which the characteristics of experiences determine different possible outcomes [ ]. In fact, during development, the brain not only stores linguistic information but also adapts to the grammatical regularities of language.Language acquisition might be oversimplified as the way in which the brain learns, perceives, represents and integrates complex sequences of verbal events. The temporal nature of sounds, structural integration, expectations, and cognitive sequencing allows the brain to construct progressively intricate representations of the environment, and with progressive maturity, even aspects of emotion or cognition not readily verbalized may be influenced by linguistically based thought processes. No matter whether it is verbal or not the new material we have to deal with, once it appears it is processed through a group of co-acting neural specific subsystems which allow us to detect, encode, temporarily hold and compare incoming stimuli with previous material, along with the decision making on what to do next. In this context, it is crucial to understand that certain characteristics of the stimulus might influence its processing and, if so, how these characteristics interact with cognitive processing. . . Evaluating incoming informationPresently, it is generally accepted that incoming information is initially processed in the working memory WM , which is a theoretical construct used to refer to the system or mechanism underlying the maintenance of task-relevant information during the performance of a cognitive task. WM is crucial for a wide range of complex cognitive activities but has a limited capacity [ -]. Enough empirical evidence supports that WM plays an important role in recognition, encoding and manipulation of task-related and concurrent distractor stimuli, while WM load influences attention modulation. In fact, the working memory central executive system [ , ], concept based on the Supervisory "ttentional System proposed by Shallice [ , ], is critical for systematizing a continuous background monitoring that searches for new relevant information, ...
