The neuropeptide oxytocin enhances the processing of positive social stimuli and improves capacity to effectively attend eye region conspecifics. To investigate neural basis these effects, we combined intranasal administration with high-resolution functional magnetic resonance imaging in a unique emotion classification task. Emotional faces were briefly presented while controlling for initial fixation, measuring subsequent movements. Oxytocin had differential effects on activity specific...
The medicalization of execution was once seen as the solution to death penalty concerns. Instead it has only spawned new legal challenges, says <b>Owen Dyer</b>, and a tightening drugs embargo that now seriously threatens US states' ability continue capital punishment
Patients with borderline personality disorder are characterized by emotional hyperarousal increased stress levels, anger proneness, and hostile, impulsive behaviors. They tend to ascribe ambiguous facial expressions exhibit enhanced prolonged reactions in response threatening social cues, associated amygdala responses. Because the intranasal administration of neuropeptide oxytocin has been shown improve recognition shift attention away from negative information, authors investigated whether...
Imaging techniques have been used to elucidate the neural correlates that underlie deception. The scientifically best understood paradigm for detection of deception, however, guilty knowledge test (GKT), was rarely in imaging studies. By transferring a GKT-paradigm functional magnetic resonance (fMRI) study, while additionally quantifying reaction times and skin conductance responses (SCRs), this study aimed at identifying behavioral electrodermal response pattern typically found GKT...
The processing of gaze cues plays an important role in social interactions, and mutual particular is relevant for natural as well video-mediated communications. Mutual occurs when observer looks at or the direction eyes another person. authors chose metaphor a cone to characterize this range directions that constitutes "looking at" In 4 experiments using either real person virtual head, investigated influences distance, head orientation, visibility eyes, presence 2nd on perceived width cone....
Life-span theories explain successful aging with an adaptive management of emotional experiences like regret. As opportunities to undo regrettable situations decline age, a reduced engagement into these represents potentially protective strategy maintain well-being in older age. Yet, little is known about the underlying neurobiological mechanisms supporting this claim. We used multimodal psychophysiological approach combination sequential risk-taking task that induces feeling regret and...
Diagnostic features of emotional expressions are differentially distributed across the face. The current study examined whether these diagnostic preferentially attended to even when they irrelevant for task at hand or faces appear different locations in visual field. To this aim, fearful, happy and neutral were presented healthy individuals two experiments while measuring eye movements. In Experiment 1, participants had accomplish an emotion classification, a gender discrimination passive...
The self-concept maintenance theory holds that many people will cheat in order to maximize self-profit, but only the extent they can do so while maintaining a positive self-concept. Mazar, Amir, and Ariely (2008, Experiment 1) gave participants an opportunity incentive on problem-solving task. Prior task, either recalled Ten Commandments (a moral reminder) or 10 books had read high school neutral task). Results were consistent with theory. When given cheat, moral-reminder priming task...
Abstract The COVID-19 pandemic and associated countermeasures had an immensely disruptive impact on people’s lives. Due to the lack of systematic pre-pandemic data, however, it is still unclear how individuals’ psychological health has been affected across this incisive event. In study, we analyze longitudinal data from two healthy samples ( N = 307) provide quasi-longitudinal insight into full trajectory burden before (baseline), during first peak, at a relative downturn pandemic. Our...
This study aimed at differentiating between memory- and task-related processes their correlates on the electrodermal electrocortical level during information concealment. Variations of Guilty Knowledge Test were implemented in two experiments while we measured skin conductance responses (SCRs) event-related brain potentials. P300 amplitudes specifically enhanced for items requiring a deviant behavioral response but they not sensitive to concealed knowledge. In contrast, N200 differed...
Abstract It has recently been suggested that learning signals in the amygdala might be best characterized by attentional theories of associative [such as Pearce–Hall ( PH )] and more recent hybrid variants combine Rescorla–Wagner models. In these models, unsigned prediction errors PE s) determine associability a cue, which is used turn to control outcome expectations dynamically reflects function reliability prior predictions. Here, we employed an aversive Pavlovian reversal‐learning task...
<h3>Background:</h3> Anxiety disorders are more prevalent in women than men. Despite this sexual dimorphism, most experimental studies conducted male participants, and focusing on sex differences sparse. In addition, the role of hormonal contraceptives menstrual cycle phase fear conditioning extinction processes remain largely unknown. <h3>Methods:</h3> We investigated context-dependent acquisition (day 1) their retrieval/expression 2). Skin conductance responses (SCRs), unconditioned...
When extreme, anxiety can become debilitating. Anxiety disorders, which often first emerge early in development, are common and challenging to treat, yet the neurocognitive mechanisms that confer increased risk have only recently begun come into focus. Here we review recent work highlighting importance of neural circuits centered on amygdala. We begin by describing dispositional negativity, a core dimension childhood temperament adult personality an important factor for development disorders...
