Association-based Concealed Information Test: A Novel Reaction Time-Based Deception Detection Method 

Lukacs, Gaspar; Bartosz, Gula; Szegedi-Hallgato, Emese; Csifcsak, Gabor (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: ...

Action-associated modulation of visual event-related potentials evoked by abstract and ecological stimuli 

Csifcsak, Gabor; Balla, Viktoria Roxana; Dalos, Vera Daniella; Kilencz, Tunde; Biro, Edit Magdolna; Urban, Gabor; Szaloki, Szilvia (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 

Rokszin, Adrienn A; Gyori-Dani, Dora; Bacsi, Janos; Nyúl, László G; Csifcsak, Gabor (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 ...

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 

Lukacs, Gaspar; Weiss, Bela; Dalos, Vera Daniella; Kilencz, Tunde; Tudja, Szabina; Csifcsak, Gabor (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] 

Boayue, Nya Mehnwolo; Csifcsak, Gabor; Puonti, Oula; Thielscher, Axel; Mittner, Matthias (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 

Turi, Zsolt; Csifcsak, Gabor; Boayue, Nya Mehnwolo; Aslaksen, Per M; Antal, Andrea; Paulus, Walter; Groot, Josephine; Hawkins, Guy E.; Opitz, Alexander; Thielscher, Axel; Mittner, Matthias (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 

Gál, Bernadett Ildikó; Kilencz, Tunde; Albert, Anita; Demeter, Ildikó; Hegedűs, Klára Mária; Janka, Zoltán; Csifcsak, Gabor; Álmos, Péter Zoltán (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 ...

A novel experimental paradigm with improved ecological validity reveals robust action-associated enhancement of the N1 visual event-related potential in healthy adults 

Balla, Viktória Roxána; Szalóki, Szilvia; Kilencz, Tünde; Dalos, Vera Daniella; Németh, Roland; Csifcsak, Gabor (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-11)
The association between an action and its sensory consequence has been linked to our sense of agency (SoA). While ecological validity is crucial in investigating such a complex phenomenon, previous paradigms focusing on the cortical analysis of movement-related images used simplified experimental protocols. Here, we examined the influence of action-associated predictive processes on visual event-related ...

Intermittent Absence of Control during Reinforcement Learning Interferes with Pavlovian Bias in Action Selection 

Csifcsak, Gabor; Melsæter, Eirik; Mittner, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-02)
The ability to control the occurrence of rewarding and punishing events is crucial for our well-being. Two ways to optimize performance are to follow heuristics like Pavlovian biases to approach reward and avoid loss or to rely more on slowly accumulated stimulus–action associations. Although reduced control over outcomes has been linked to suboptimal decision-making in clinical conditions associated ...
