The present study has 1 primary and 1 secondary objective:1: The primary objective of the present study is to analyse the effects of supplementation with ITFs of different chain lengths and RSC on hepatitis B vaccination efficacy. The main parameter…
Primary objective is to examine the effect of tryptophan supplementation on the number of accepted unfair offers in the Ultimatum Game. Secondary objectives are to examine the effect of tryptophan supplementation on the response bias in a social…
We aim to assess the neurocognitive mechanisms of tyrosine supplementation in older adults during different forms of cognitive control depending on the prefrontal cortex: working memory, reactive and proactive response inhibition, and effort…
To decrease social conformity by disrupting orbitofrontal cortex by using transcranial direct current stimulation.
To investigate the dynamic relationship between hemodynamic responses to different levels of acute SERT occupancy induced by different doses of the reuptake inhibitor (SSRI) citalopram with 5-HT phMRI, as compared to [123I]FP-CIT SPECT imaging.…
This study aims to investigate the effects of a behavioral intervention which is aimed at the improvementenhancing of parental sensitivity and sensitive disciplinary techniques to on the development of children*s social competence and behavioral…
The aim of the study is: to investigate the effect of DCS on the physiological and subjective correlates reflecting conditioned sexual response and subsequent extinction thereof. Hypothesis: We hypothesize that administration of DCS after an…
The current study aims to investigate the effects of catecholamine modulation by methylphenidate during initial stages of consolidation on memory retention and the underlying neural correlates of memory retrieval.
Objective: This study will investigate if AIM can be trained among people with chronic anger management processes. According to the AIM model, repeating avoidance responses to threatening stimuli may reduce aggressive impulses within this population…
The objective of this exploratory study is to investigate the acid neutralisation action of sodium alginate oral suspension versus placebo liquid, within the stomach and to assess suitability and robustness of the pH monitoring methodology.
Primary objective:- To identify the psychological mechanisms via which testosterone modulates value-based decision making, such as testosterone's effects on risk-taking levels, impulsivity and self-control in intertemporal choice, and social…
The primary objective of this study is to establish a causal role of the alpha band oscillations in lateralized parieto-occipital areas during spatial updating with whole-body translation using online transcranial alternating current stimulation (…
To enhance learning by entraining theta oscillations in the frontal cortex using transcranial alternating current stimulation
This study will investigate the counter impulse hypothesis. According to the counter-impulse hypothesis, avoidance motivation counters aggressive impulses. Consequently, this regulatory impact should be especially effective when people*s aggressive…
To record all reactions of healthy volunteers induced by the use of a homeopathic medicine and placebo.
1) To determine whether vaccination with yellow fever results in a higher cytokine response upon restimulation in vitro with non-related infectious pathogens, compared to the response before the vaccination.2) To determine whether BCG vaccination…
To elucidate the changes in the timing of sleep and waking, sleep quality and endogenous circadian phase in different chronotypes (e.g. *owls* vs. *larks*) with different amounts of social jetlag shielded from short wavelength (blue) light in the…
The goal of the present study is to investigate whether the blockade of NA-transmission by beta-antagonist propranolol reduces the common EMDR effects (reduced vividness/emotionality of emotional memories) in order to find out if NA-release (evoked…
The aim is to specify the role of the vlPFC in the control of social emotional behavior. We will combine transcranial direct current stimulation (tDCS) and a modified version of the joystick affective AAT involving posturography (to assess postural…
Primary objectiveDoes administration of THC produce an increase in subcortical dopamine level of chronic cannabis users? Does this effect on dopamine modulate the link between spontaneous eye blink rate, performance on divergent and convergent…
