We investigated how viewing task-irrelevant emotional pictures affects the performance of a subsequent nonemotional visual detection task. Subjects performed target-detection trials following offset individual unpleasant, pleasant, and neutral pictures. Sustained interference occurred when subjects viewed unpleasant (mutilated bodies) in sequential, "blocked" fashion. Such slowing down reaction time appeared to build up with time, consistent instatement defensive state. With randomized...
The prioritization of processing emotional stimuli usually produces deleterious effects on task performance when it distracts from a task. One common explanation is that brain resources are consumed by stimuli, diverting away executing the Viewing unpleasant also generates defensive reactions, and these responses may be at least partially responsible for effect modulation observed in various reaction time (RT) paradigms. We investigated whether modulatory RT vary if we presented threat to...
It is assumed that social bonds in humans have consequences for virtually all aspects of behavior. Social touch-based contact, particularly hand caressing, plays an important role bonding. Pre-programmed neural circuits likely support actions (or predispositions to act) towards caressing contacts. We searched pre-set motor substrates by exposing volunteers bonding cues and having them gently stroke a very soft cloth, caress-like movement. The were pictures with interacting dyads the control...
Background Ultra-processed foods (UPF) are becoming extensively available in the food environments. UPF industrial formulations that designed to maximize palatability and consumption through a combination of calorie-dense ingredients chemical additives. UPFs also aggressively marketed, which may make them more attractive than unprocessed/minimally processed (UMPF). Since consumers' purchase decisions guided by food-evoked emotions, we aimed provide evidence visual cues trigger higher...
Responding to pro-social cues plays an important adaptive role in humans. Our aims were (i) create a catalogue of bonding and matched-control pictures compare the emotional reports valence arousal with International Affective Picture System (IAPS) pictures; (ii) verify sex influence on (iii) investigate if empathy loneliness traits exert specific for pictures. To provide finer tool social interaction studies, present work defined two new sets consisting "interacting dyads" (Bonding: N=70)...
Abstract Associating a novel situation with specific outcome involves cascade of cognitive processes, including selecting relevant stimuli, forming predictions regarding expected outcomes, and updating memorized based on experience. The present manuscript uses computational modeling machine learning to test the hypothesis that alpha‐band (8–12 Hz) oscillations are involved in expectations Participants learned visual cue predicted an aversive loud noise probability 50%. Rescorla–Wagner model...
Background and objectives Ultra-processed food products (UPF) have been associated with numerous non-communicable diseases. Despite this, the addictive nature of UPF, aggressive marketing strategies used to promote them, has created a strong emotional connection between UPF consumers, supports their increasing global consumption. In view link that consumers often modulating reactions (by using such as textual warnings) is important in changing consumers’ behavior. Since emotions are better...
Viewing pictures of social interaction can facilitate approach behaviors. We conducted two studies to investigate if cues, empathy, and/or touch modulate facial electromyographic (EMG) reactivity (as evidenced by the zygomaticus major and corrugator supercilii muscles) mood states. presented bonding (depicting interaction) control (without while continuously recording zygomatic EMG activities. In both studies, picture blocks were paired valence arousal. All participants college students....
Victims of urban violence are at risk developing Posttraumatic Stress Disorder (PTSD), one the most debilitating consequences violence. Considering that PTSD may be associated with inefficient selection defensive responses, it is important to understand relation between motor processing and PTSD. The present study aims investigate extent which severity posttraumatic stress symptoms (PTSS) related preparation against visual threat cues in victims Participants performed a choice reaction time...
O consumo de alimentos ultraprocessados tem crescido vertiginosamente nas últimas décadas, trazendo consequências para a saúde humana e ambiental. Dentre as estratégias defesa estão os modelos rotulagem frontal como forma reduzir o apelo positivo evocado por esses alimentos. eles, modelo em semáforo utiliza um sistema cores informar consumidor sobre nutrientes críticos (como açúcares, sal, gordura) presentes excesso no alimento. Em estudo realizado pelo nosso grupo pesquisa, investigamos...
Proximity and interpersonal contact are prominent components of social connection. Giving affective touch to others is fundamental for human bonding. This brief report presents preliminary results from a pilot study. It explores if exposure bonding scenes impacts the activity specific muscles related physical interaction. Fingers flexion very important component when performing most actions affectionate contact. We explored visuo-motor interplay by priming participants with assessing...
Loneliness has emerged as a public health concern. Previous research reported its deleterious effects on physical and mental health; however, some specific psychophysiological mechanisms in healthy adults remain to be elucidated. The aim of the current study is investigate whether self-reported social support touch (giving receiving touch), well resting heart rate variability (HRV), are significant negative predictors loneliness adults. sample consists 120 students (50% female) with mean age...

Oscillatory activity in the alpha band (8–13 Hz) is among most prominent aspect of scalp-recorded EEG signal. Changes power have been related to a spectrum behavioral and cognitive processes. Recent research has converged demonstrate that selectively heightened when participants report states mind-wandering, active imagery, internal/anticipatory processing, as well suppression distracting stimuli. A major portion this involved trial averaging shown paradigm-specificity along with pronounced...
