Association-based Concealed Information Test: A Novel Reaction Time-Based Deception Detection Method
(Journal article; Tidsskriftartikkel, 2017-07-15)
In recent years, numerous studies were published on the reaction time (RT)-based Concealed Information Test (CIT). However, an important limitation of the CIT is the reliance on the recognition of the probe item, and therefore the limited applicability when an innocent person is aware of this item. In the present paper, we introduce an RT-based CIT that is based on item-category associations: ...
Linking brain networks and behavioral variability to different types of mind-wandering

Action-associated modulation of visual event-related potentials evoked by abstract and ecological stimuli
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-09-19)
This study investigated the influence of action‐associated predictive processes on visual ERPs. In two experiments, we sought evidence for sensory attenuation (SA) indexed by ERP amplitude reductions for self‐induced stimuli when compared to passive viewing of the same images. We assessed if SA is (a) present for both ecological and abstract stimuli (pictures depicting hands or checkerboards), (b) ...
Tracking changes in spatial frequency sensitivity during natural image processing in school age: an event-related potential study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-09)
Several studies have shown that behavioral and electrophysiological correlates of processing visual images containing low or high spatial frequency (LSF or HSF) information undergo development after early childhood. However, the maturation of spatial frequency sensitivity in school-age has been investigated using abstract stimuli only. The aim of the current study was to assess how LSF and HSF ...
Effects of transcranial direct current stimulation for treating depression: A modeling study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-28)
<p><i>Background</i>: Transcranial direct current stimulation (tDCS) above the left dorsolateral prefrontal cortex (lDLPFC) has been widely used to improve symptoms of major depressive disorder (MDD). However, the effects of different stimulation protocols in the entire frontal lobe have not been investigated in a large sample including patient data.</p> <p><i>Methods</i>: We used 38 head ...
The first independent study on the complex trial protocol version of the P300-based concealed information test: Corroboration of previous findings and highlights on vulnerabilities
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-15)
More than a dozen studies of the Complex Trial Protocol (CTP) version of the P300-based Concealed Information Test have been published since its introduction (Rosenfeld et al., 2008), and it has been fairly consistently proven to provide high accuracy and strong resistance to countermeasures (Rosenfeld et al., 2013). However, no independent authors have verified these findings until now. In the ...
Head models of healthy and depressed adults for simulating the electric fields of non-invasive electric brain stimulation [version 2; referees: 2 approved]
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-06)
During the past decade, it became clear that the electric field elicited by non-invasive brain stimulation (NIBS) techniques such as transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) are substantially influenced by variations in individual head and brain anatomy. In addition to structural variations in the healthy, several psychiatric disorders are characterized ...
Blinding is compromised for transcranial direct current stimulation at 1 mA for 20 min in young healthy adults
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-19)
Transcranial direct current stimulation (tDCS) is a non‐invasive brain stimulation method that is frequently used to study cortical excitability changes and their impact on cognitive functions in humans. While most stimulators are capable of operating in double‐blind mode, the amount of discomfort experienced during tDCS may break blinding. Therefore, specifically designed sham stimulation protocols ...
Mild Effect of Nalmefene on Alcoholic Cue-Induced Response Invigoration in Alcohol Use Disorder Without Accompanying Changes in Electrophysiological Signatures of Early Visual Processing and Executive Control
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-26)
Nalmefene is approved for as-needed pharmacological treatment in alcohol use disorder (AUD) by the European Medicines Agency. While the cellular effects of nalmefene have been thoroughly investigated, data are very limited on how this agent influences neural signals associated with inhibitory control and the visual analysis of environmental cues. This double-blind crossover study assessed the ...
Increasing propensity to mind‐wander by transcranial direct current stimulation? A registered report
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2019-01-24)
Transcranial direct current stimulation (tDCS) has been proposed to be able to modulate different cognitive functions. However, recent meta‐analyses conclude that its efficacy is still in question. Recently, an increase in subjects’ propensity to mind‐wander has been reported as a consequence of anodal stimulation of the left dorsolateral prefrontal cortex (Axelrod et al., Proceedings of the National ...
