A fejlődési diszlexia újabb vizsgálatai az olvasási zavar mellett gyakran mutatnak ki teljesítménycsökkenést egyrészt a végrehajtó funkciókban (pl. munkamemória-feladatokban), másrészt vizuális tesztekben. Utóbbiak a vizuális feldolgozás ventrális útvonalának féltekei lateralizációt mutató, magasabbrendű, komplex információfeldolgozási zavarára uta...
Article
Abstract The presence of noise usually impairs the processing of a stimulus. Here, we studied the effects of noise on face processing and show, for the first time, that adaptation to noise patterns has beneficial effects on face perception. We used noiseless faces that were either surrounded by random noise or presented on a uniform background as s...

Deficits in error-processing are postulated in core symptoms of ADHD. Our goal was to investigate the neurophysiological basis of abnormal error-processing and adaptive adjustments in ADHD, and examine whether error-related alterations extend beyond traditional Regions of Interest (ROIs), particularly to those involved in adaptive adjustments, such...
Article
Full-text available
A central issue in sequence learning is whether learning operates on stimulus independent abstract elements, or whether participants integrate surface features of ordered stimuli, resulting in stimulus dependent learning. Using the Serial Reaction-Time Task (SRT), the current study tests whether a previously presented sequence is transferrable from...
Thesis
Face is a unique stimulus category in the human central nervous system. One of the most obvious evidence for that is provided by a neuropsychological disease called prosopagnosia. The aim of the thesis is to assess the neural background of the normal and impaired face recognition abilities, especially the category-sensitivity of core face processin...
Article
Full-text available
Previous studies have suggested that the human visual system processes faces and bodies holistically, that is, the different body-parts are integrated into a unified representation. However, the time course of this integrative process is less known. In the present study, we investigated this issue by recording event-related potentials evoked by a f...
Article
Full-text available
Several studies demonstrated that face perception is biased by the prior presentation of another face, a phenomenon termed as face-related after-effect (FAE). FAE is linked to a neural signal-reduction at occipito-temporal areas and it can be observed in the amplitude modulation of the early event-related potential (ERP) components. Recently, macaq...
Article
Prosopagnosia is a disorder of recognition of familiar faces, without visual or cognitive dysfunction. While the acquired type is primarily due to the injury of occipito-temporal areas, the neural background of the congenital form seems to be more heterogeneous. In addition to the variability in neurological dysfunctions, symptom severity also show...
Article
Congenital prosopagnosia is a life-long disorder of face perception. To study the neural backgrounds of congenital prosopagnosia we measured the blood oxygen level-dependent response of congenital prosopagnosic participants, using functional magnetic resonance imaging. We tested three persons of the family (father, daughter and son), having symptom...
Article
Previous studies demonstrated that the steady-state visual-evoked potential (SSVEP) is reduced to the repetition of the same identity face when compared with the presentation of different identities, suggesting high-level neural adaptation to face identity. Here we investigated whether the SSVEP is sensitive to the orientation, viewpoint, expressio...
Poster
Individuals with developmental prosopagnosia are unable to identify familiar people via their faces, despite normal low-level vision and intellect and in the absence of any obvious damage of the central nervous system. Previous results suggested the existence of different types of prosopagnosia, however to date the selective role of the perceptual,...
Article
Full-text available
Congenital prosopagnosia is lifelong face-recognition impairment in the absence of evidence for structural brain damage. To study the neural correlates of congenital prosopagnosia, we measured the face-sensitive N170 component of the event-related potential in three members of the same family (father (56y), son (25y) and daughter (22y)) and in age-...
Article
Full-text available
The spatial distances among the features of a face are commonly referred to as second-order relations, and the coding of these properties is often regarded as a cornerstone in face recognition. Previous studies have provided mixed results regarding whether the N170, a face-sensitive component of the event-related potential, is sensitive to second-o...
Article
Full-text available
Previous studies have found that the amplitude of the early event-related potential (ERP) components evoked by faces, such as N170 and P2, changes systematically as a function of noise added to the stimuli. This change has been linked to an increased perceptual processing demand and to enhanced difficulty in perceptual decision making about faces....
Article
It is known that the amplitude of early face evoked event-related potential (ERP) components, such as the N170 and P2, changes systematically as a function of added noise. In a previous study we investigated whether phase-noise manipulation affects the neural correlates of face versus non-face decisions similarly. To this end, using an age-discrimi...

Our paper is an attempt to indicate the relevance of information theoretical accounts to understand word recognition and morphological processing in Hungarian, along with other studies using more traditional predictors like linear position and morphological composition. The first two experiments were gating studies. The effect of the decision point...
Article
Mild Cognitive Impairment (MCI) causes slight but noticeable disruption in cognitive systems, primarily executive and memory functions. However, it is not clear if the development of sequence learning is affected by an impaired cognitive system and, if so, how. The goal of our study was to investigate the development of probabilistic sequence learn...
Article
This article aims to investigate the possible impact of carotid stenosis, i.e., the atherosclerotic narrowing of the inner surface of the carotid artery, on language performance. The majority of patients with carotid stenosis are considered asymptomatic, as they have not experienced retinal or focal cerebral dysfunction. Here we challenge the tradi...
Conference Paper
In previous studies it has been found that adding noise to faces modulates the amplitude of the N170 and P2 components of the event-related potential (ERP) incrementally. However, to date it has not been investigated whether this manipulation affects the ERP for non-face stimuli to the same extent as well. To this end, we measured the event related...
Article
Since brain ischemia is one of the leading causes of adult disability and death, neuroprotection of the ischemic brain is of particular importance. Acute neuroprotective strategies usually have the aim of suppressing glutamate excitotoxicity and an excessive NMDA receptor function. Clinically tolerated antagonists should antagonize an excessive NMD...
Article
Full-text available
After prolonged exposure to a distorted face with expanded or contracted inner features, a subsequently presented normal face appears distorted toward the opposite direction. This phenomenon, termed as face distortion aftereffect (FDAE), is thought to occur as a result of changes in the mechanisms involved in higher order visual processing. However...
Conference Paper
The study of steady-state visual-evoked potentials (SSVEPs) is a promising tool in investigating how the brain processes visual information related to human faces. A recent study has shown that the repetition of individual faces results in the habituation of the SSVEP response at the fundamental stimulation frequency over posterior temporal electro...
Conference Paper
Prosopagnosia (PA) is a syndrome where various aspects of face perception are impaired. A specific and quite rare type of PA is the so-called congenital prosopagnosia (CP) which is inherited and occurs without any visible damage to the neural system. In our current experiments we studied the neural bases of CP in three patients of the same family (...
Article
Stimulation of the visual system at a given frequency evokes an oscillatory electrical brain response—the steady-state visual-evoked potential (SSVEP). A recent study has shown that the repetition of the same face results in the habituation of the SSVEP responses compared to a condition in which faces of different identities are presented (Rossion...
Article
Congenital prosopagnosia (CP) is a life-long disorder of face perception. We investigated the neural bases of CP in three patients of a family (father, daughter and son), as well in healthy, age-matched controls, using combined neuropsychological, electrophysiological and functional magnetic resonance imaging (fMRI) methods. Neuropsychological test...
Article
Congenital prosopagnosia (CP) is a long-life impairment in face recognition despite normal low-level visual processing. Previously several case studies investigated different aspects of CP. However, there are no complex studies describing the whole neuropsychological, behavioural and electrophysiological profile of these subjects as of yet. The goa...
Article
Due to the last two decades of escalated technical development IQ researchers nowadays have to integrate some new pieces of empirical evidence coming from neuroscience. At the beginning of the 21st century the research of the neural background of intelligence arrived to a new chapter owing to the simple availability of functional imaging techniques...

As the literature about directed forgetting says we are able to supress our unwanted memories. Anderson & Green’s theory (2001) states that these items are under inhibition and we can’t evoke them. However, according to a recent theory (Racsmány & Conway, 2006) items are available, but not accessible, and not the items themselves, but rather their...

Our study investigated the development of the language and memory systems and the degree of involvation of procedural and working memory in language processes in different ages. In three age groups we tested working memory by Digit Span and Listening Span tests, the learning efficiency of the procedural memory by ASRT, on-line sentence comprehensio...

Question
We have an iView X HS 1250 SMI eye-tracker System which is not working now. The system was not used in the last 4 months at all and now when we would like to start the measurements, the iViewX program cannot link to the camera. If I go to hardware configuration it says: "Couldn't open camera link connection to C:\Windows\system32\clseremc.dll Please close other application with open connections to the camera.". Another Error message when tried to configure hardware again: "couldn't allocate channel. Please reconfigure the grabber."
Do you have any idea? Do you know whether SMI successor ( https://gazeintelligence.com) provides remote support - e.g via TeamViewer?
Thanks.
Question
It would be great to see a working script for a gaze-contingent experiment, however, I didn't find useful information in the manuals.
I'm able to start, pause, continue, stop, save eye-tracker but most of the ET_... commands do not work.
I'm using Psychtoolbox 3.0.8 under matlab 2008a.
Thanks.
Question
Hey,
No error message, no warning. The desktop is simply restarting itself... the script is working fine on my laptop. Windows' log says nothing about the crash event.
I tried several combinations of matlab (2014a, 2017b) and eeglab (12, 14...). This is a win10 x64 operation system (similar to my laptop).
"EEG = pop_runica(EEG, 'extended',1,'interupt','on','icatype','runica'); "
Question
Instead of the labels provided by the Biosemi (A0001...) I would like to identify and code the electrodes using standard 10/20 labels (e.g. P8, Cz, Fp1). Any idea? Thanks.
