Recent research suggests that the allocation of attentional resources to emotional content during word processing might be sensitive task requirements. This question was investigated in two tasks with similar instructions. The stimuli were positive, negative, and neutral nouns. Participants had identify meaningful words embedded a stream non-recognizable (task 1) or pseudowords 2). Task 1 could successfully performed on basis perceptual features whereas lexico-semantic analysis required 2....
Abstract Memory for aversive events is central to survival but can become maladaptive in psychiatric disorders. enhancement emotional thought depend on amygdala modulation of hippocampal activity. However, the neural dynamics amygdala-hippocampal communication during memory encoding remain unknown. Using simultaneous intracranial recordings from both structures human patients, here we show that successful depends theta phase which gamma activity and neuronal firing couple. The difference...
Current models of affective processing postulate that not only valence but also the arousal dimension characterizes emotional experience. However, up-to-date research on priming has mainly focused contributions congruency to priming. In this study, authors explored possible influence in processes. For purpose, event-related potentials and reaction times were measured response high- low-arousing positive targets either congruent or incongruent with a prime word. Priming did times. By...
Abstract It has been proposed that the human amygdala may not only encode emotional value of sensory events, but more generally mediate appraisal their relevance for individual’s goals, including action or task-based needs. However, and non-emotional/action-relevance might drive activity through distinct neural signals, relative timing both kinds responses remains undetermined. Here, we recorded intracranial event-related potentials from nine amygdalae patients undergoing epilepsy surgery,...
To perceive a coherent environment, incomplete or overlapping visual forms must be integrated into meaningful percepts, process referred to as "Gestalt" formation perceptual completion. Increasing evidence suggests that this engages oscillatory neuronal activity in distributed assembly. A separate line of Gestalt requires top-down feedback from higher order brain regions early cortex. Here we combine magnetoencephalography (MEG) and effective connectivity analysis the frequency domain...
Initial evaluation structures (IESs) currently proposed as the earliest detectors of affective stimuli (e.g., amygdala, orbitofrontal cortex, or insula) are high-order (a) whose response latency cannot account for first visual cortex emotion-related (~80 ms), and (b) lack necessary infrastructure to locally analyze features that define emotional stimuli. Several thalamic accomplish both criteria. The lateral geniculate nucleus (LGN), a first-order actively processes information, with...
In fear conditioning, more efficient sensory processing of a stimulus (the conditioned stimulus, CS) that has acquired motivational relevance by being paired with an aversive event unconditioned US) been associated increased cortical gain in early brain areas (Miskovic and Keil, 2012). Further, this modulation related to short-term plasticity changes occurs independently aware cognitive anticipation the US, pointing toward implicit learning mechanisms (Moratti 2009). However, it is unknown...
Abstract Exogenous attention allows the automatic detection of relevant stimuli and reorientation our current focus towards them. Faces from an ethnic outgroup tend to capture exogenous a greater extent than faces ingroup. We explored whether prejudice toward outgroup, rather lack familiarity, is driving this effect. Participants (N = 76) performed digit categorization task while distractor were presented. belonged (i) prejudiced (ii) non-prejudiced (iii) their Half previously habituated in...
Abstract Scarce previous data on how the location where an emotional stimulus appears in visual scene modulates its perception suggest that, for functional reasons, a perceptual advantage may exist, vertically, stimuli presented at lower field (LoVF) and, horizontally, left (LeVF). However, this issue has been explored through limited number of spatial locations, usually single dimension (e.g., horizontal) and invariant eccentricities. Event‐related potentials (ERPs) were recorded from 39...
In unpredictable environments, stimuli that predict potential danger or its absence can change rapidly. Therefore, it is highly adaptive to prioritize incoming sensory information flexibly as a function of prior experience. Previously, these changes have only been conceptualized excitatory gain increases in cortices for acquired fear-relevant during associative learning. However, formal descriptions processes by Rescorla and Wagner both conditioned inhibitory response systems fear safety...
Habituation to ethnic ingroup members has been reported be greater than outgroup members. This pattern could due the lack of perceptive experience (familiarity) with facial morphs or, alternatively, prejudice held toward that outgroup. We explored this disjunctive in 71 participants, all Spanish, who were experimentally habituated faces from their Ingroup and two unfamiliar outgroups, one for which there is low probability population (Non-prejudiced Outgroup), higher (Prejudiced Outgroup)....
Several studies suggest that the menstrual cycle affects emotional processing. However, these results may be biased by including women with premenstrual syndrome (PMS) in samples. PMS is characterized negative symptomatology, such as depression and/or anxiety, during luteal phase. This study aimed to explore modulation of exogenous attention facial expressions a function without PMS. For this purpose, 55 were selected (from an original volunteer sample 790) according rigorous exclusion...
Abstract Previous research shows that endogenous attention (the controlled selection of certain aspects our environment) is enhanced toward emotional stimuli due to its biological relevance. Although looming affective such as threat seem even more critical for survival, little known about their effect on attention. Here, we recorded neural (event‐related potentials, ERPs) and behavioral responses (errors reaction times) explore the combined emotion motion. 3D‐recreated static moving animals...
Abstract Previous research shows that dynamic stimuli, on the one hand, and emotional other, capture exogenous attention due to their biological relevance. Through neural (ERPs) behavioral measures (reaction times errors), present study explored combined effect of looming motion content attentional capture. To this end, 3D-recreated static animals assessed as (positive or negative) neutral were presented distractors while 71 volunteers performed a line orientation task. We observed two-phase...
Current proposals on the temporal sequence in processing of emotional visual stimuli are partially incompatible with growing empirical data. In majority them, initial evaluation structures (IES) postulated to be charge earliest detection (i.e., salient for individual), high order those receiving inputs after several synapses). Thus, their latency response cannot account first cortex (peaking 80 ms humans). Additionally, these proposed lack necessary infrastructure locally analyze features...
