Curiosity is one of the most basic biological drives in both animals and humans, has been identified as a key motive for learning discovery. Despite importance curiosity related behaviors, topic largely neglected human neuroscience; hence little known about neurobiological mechanisms underlying curiosity. We used functional magnetic resonance imaging (fMRI) to investigate what happens our brain during induction subsequent relief perceptual Our core findings were that (i) curiosity, through...
The conflict-adaptation effect has been observed in several executive-control tasks and is thought to reflect an increase control, driven by experienced conflict. We hypothesized that if this adaptation originates from the aversive quality of conflict, it would be canceled out a positive, rewarding event. Subjects performed arrow flanker task with monetary gain or loss as arbitrary feedback between trials. As predicted, we found reduction conflict for trials which was followed gain. strength...
Cognitive conflict plays an important role in tuning cognitive control to the situation at hand. On basis of earlier findings demonstrating emotional modulations processing, we predicted that affective states may adaptively regulate goal-directed behavior is driven by conflict. We tested this hypothesis measuring conflict-driven adaptations following experimental induction four different mood could be differentiated along dimensions arousal and pleasure. After were induced, 91 subjects...
Performing online behavioral research is gaining increased popularity among researchers in psychological and cognitive science. However, the currently available methods for conducting reaction time experiments are often complicated typically require advanced technical skills. In this article, we introduce Qualtrics Reaction Time Engine (QRTEngine), an open-source JavaScript engine that can be embedded survey development environment Qualtrics. The QRTEngine used to easily develop...

Cognitive demands in response conflict paradigms trigger negative affect and avoidance behavior. However, not all studies show increases physiological indices of emotional arousal, such as pupil diameter. In contrast to earlier null-results, this study shows for the first time that small (about 0.02 mm) conflict-related dilation can be observed a Simon task when stimuli do introduce light reflex. Results response-conflict trials induces both reaction-time costs. Moreover, sequential analyses...
The present study investigated resource allocation, as measured by pupil dilation, in tasks measuring updating (2-Back task), inhibition (Stroop task) and switching (Number Switch task). Because each cognitive control component has unique characteristics, differences patterns of allocation were expected. Pupil behavioral data from 35 participants analyzed. In the 2-Back task (requiring correct matching current stimulus identity at trial p with two trials back, -2) we found that better...
Abstract While animal studies have demonstrated a unique reproduction-related neuroplasticity, little is known on the effects of pregnancy human brain. Here we investigated whether associated with changes to resting state brain activity, white matter microstructure, neural metabolite concentrations and grey architecture using comprehensive pre-conception cohort study. We show that leads selective robust in network organization, which are most pronounced Default Mode Network. These correlated...
It has been shown that negative affect causes attentional narrowing. According to Easterbrook's (1959) influential hypothesis this effect is driven by the withdrawal motivation inherent emotions and might be related increases in arousal. We investigated whether valence-unspecific physiological arousal, as measured pupil dilation, could account for narrowing effects a cognitive control task. Following presentation of negative, positive, or neutral picture, participants performed saccade task...
Social anxiety disorder (SAD) is a prevalent and disabling mental disorder, associated with significant psychiatric co-morbidity. Previous research on structural brain alterations SAD has yielded inconsistent results concerning the direction of changes in gray matter (GM) various regions, as well relationship between structure SAD-symptomatology. These heterogeneous findings are possibly due to limited sample sizes. Multi-site imaging offers new opportunities investigate SAD-related larger...
Positive affect can help to dampen the impact of adverse life events, facilitating healthy cognitive and emotional functioning after stress. The present review highlights recent findings on stress buffering effects these pleasant feeling states, focusing studies utilizing acute chronic in daily life, manipulations lab, examinations affective adaptations during tasks involving difficult or risky events. We novel that neural reward systems activity brain areas involved signalling highlight...
The present multimodal MRI study advances our understanding of the corticostriatal circuits underlying goal-directed vs. cue-driven, habitual food seeking. To this end, we employed a computerized Pavlovian-instrumental transfer paradigm. During test phase, participants were free to perform learned instrumental responses (left and right key presses) for popcorn Smarties outcomes. Importantly, prior half had been sated on other - resulting in reduced desirability those Furthermore, during...
Social anxiety disorder (SAD) is a disabling psychiatric condition with genetic background. Brain alterations in gray matter (GM) related to SAD have been previously reported, but it remains be elucidated whether GM measures are candidate endophenotypes of SAD. Endophenotypes measurable characteristics on the causal pathway from genotype phenotype, providing insight genetically-based disease mechanisms. Based review existing evidence, we examined meet two endophenotype criteria, using data...
Stress evokes a complex repertoire of psychological and physiological responses associated with the appraisal challenge or threat. This paper introduces Leiden Stroop-like Task (LSST), paradigm designed to induce progressively increasing levels stress related changes in challenge-threat dynamics by manipulating time pressure (task difficulty), ability achieve task goal (uncontrollability), negative feedback (social-evaluative threat) throughout four 10-minute blocks. Fifty-four healthy...
