AB  - In addition to difficulties in social interaction and communication,
children with autistic spectrum disorder (ASD) also exhibit behaviors
that interfere with daily activities and are difficult to control, which
can lead to disturbances in the household and extended family. The
child’s limited social, emotional and communicative abilities, their
unequal cognitive development and maladaptive behaviors are a
source of stress for parents. The goal of our study was to assess the
level of stress in parents of children with ASD in relation to gender,
education, age of parents, the child’s age, and speech and language
skills. The sample of this study consisted of 40 parents (20 mothers
and 20 fathers) 21 to 56 years of age. All respondents were parents of
children with ASD; 22 were parents of children receiving treatment
at the Institute for Experimental Phonetics and Speech Pathology
„Đorđe Kostić“ and 18 parents were members of the Association of
parents of children with autism. In this study, we used The Parental Stress Scale (Berry & Jones, 1995) to assess the level of stress among
parents. The results show that there are no statistically significant
differences in the level of stress in relation to parental sex, parental age,
the child’s age and child’s expressive language development. We found
a statistically significant effect of parental education level (p=0.005),
child’s receptive language development (p=0.008), and child’s verbal
communication development (p=0.015) on parental stress level.
Parental lower education level, child’s inability to understand speech,
and undeveloped verbal communication of the child can lead to greater
parental stress. The stress of parents can significantly complicate and
slow down the process of child rehabilitation. It is important to know
that it is equally necessary to support fathers and mothers, parents
of all ages, parents of children of all ages and different speech and
language skills and that particular attention should be given to
parents with lower education.
AB  - Pored poteškoća u oblasti socijalne interakcije i komunikacije,
deca sa autističkim spektrom poremećaja (ASP) ispoljavaju ponašanje
koja ometa svakodnevne aktivnosti, što može dovesti do teškoća u
funkcionisanju uže i šire porodice. Ograničene socijalne, emotivne i
komunikativne sposobnosti dece sa ASP, njihov neujednačen kognitivni
razvoj i maladaptivno ponašanje su izvor stresa za roditelje.
Cilj našeg istraživanja bio je da se proceni nivo stresa kod roditelja
dece sa ASP u odnosu na pol, uzrast, obrazovanje i starost roditelja
kao i u odnosu na govorno-jezičke sposobnosti deteta (ekspresivni/
receptivni govor, upotreba govora u službi komunikacije). Uzorak je
činilo 40 roditelja (20 majki i 20 očeva) starosti od 21 do 56 godina. Svi
ispitanici su bili roditelji dece sa ASP, od kojih je 22 roditelja dece koja
su na tretmanu u Institutu za eksperimentalnu fonetiku i patologiju
govora “Đorđe Kostić” i 18 roditelja koji su članovi Udruženja roditelja
dece sa autizmom. U ovoj studiji, koristili smo Skalu za procenu nivoa
roditeljskog stresa (Parental Stress Scale – Berry & Jones, 1995). Rezultati
pokazuju da ne postoje statistički značajne razlike u nivou roditeljskog
stresa u odnosu na pol i starost roditelja, uzrast deteta i razvijenost
ekspresivnog govora. Na nivo roditeljskog stresa dece sa ASP značajno
utiču nivo obrazovanja roditelja (p=0,005), razvijenost receptivnog
govora (p=0,008), i razvijenost verbalne komunikacije kod deteta
(p=0,015). Niži obrazovni nivo i teškoće u produkciji i razumevanju
govora kod deteta mogu da budu uzrok višeg nivoa roditeljskog stresa.
Primenom linearne regresije utvrđeno je da stepen obrazovanja roditelja
i razvijenosti razumevanja (receptivni govor) govora kod deteta, kao
prediktori predstavljaju statistički značajno prediktivan model kojim
se može predvideti nivo roditeljskog stresa. Roditeljski stres može
značajno komplikovati i usporiti proces rehabilitacije deteta. Važno je znati da je pomoć i podrška podjednako potrebna roditeljima različitih
starosnih grupa, roditeljima dece različite starosti i različitih verbalnih
sposobnosti. Posebno je potrebna podrška i pomoć roditeljima nižeg
obrazovanja.

deteta unutar epizoda zajedničke pažnje, empatija deteta, kao i

AB  - This paper represents a review of current studies of communication
and affective characteristics in dyads of children with autistic spectrum
disorder and their parents. The review is aimed at establishing if specific
features of communication exist in this population when there is an
interaction with a close partner. In an attempt to describe the basic
characteristics of these dyads, advantage is given to the deficit in
nonverbal communication shown by children with autistic spectrum
disorder, especially the joint attention deficit. Also, the dyads are
described from the perspective of coordination of affect. Affective
reactions of the child are described within the dyads, including empathy.
Numerous study results focusing on emotional reactions of the mother
are reviewed. After describing the characteristics, the question is posed
concerning the strategies used in the dyads in difficult communication
phases or following communication break offs. In an attempt to describe
the characteristics of the other partner in communication – the parent,
stress and fatigue are especially treated. These factors have a strong
influence on everyday interactions of the parent and child. We have
accented the importance of careful examination of these factors when
making decisions on therapeutic interventions, because they need to be
based on parents’ strengths.

AB  - The paper discusses the changes in relations of visual and auditory inputs between the hemispheres in a child with hyperactive syndrome and its effects which may lead to better attention engagement in auditory and visual information analysis. The method included the use of cartographic EEG and clinical procedure in a 10-year-old boy with hyperactive syndrome and attention deficit disorder, who has theta dysfunction manifested in standard EEG. Cartographic EEG patterns was performed on NihonKohden Corporation, EEG – 1200K Neurofax apparatus in longitudinal bipolar electrode assembly schedule by utilizing10/20 International electrode positioning. Impedance was maintained below 5 kΩ, with not more than 1 kΩ differences between the electrodes. Lower filter was set at 0.53 Hz and higher filter at 35 Hz. Recording was performed in a quiet period and during stimulation procedures that include speech and language basis.Standard EEG and Neurofeedback (NFB) treatment indicated
higher theta load, alpha 2 and beta 1 activity measured in the
cartographic EEG which was done after the relative failure of NFB
treatment. After this, the NFB treatment was applied which lasted for
six months, in a way that when the boy was reading, the visual input
was enhanced to the left hemisphere and auditory input was reduced
to the right hemisphere. Repeated EEG mapping analysis showed that
there was a significant improvement, both in EEG findings as well as
in attention, behavioural and learning disorders. The paper discusses
some aspects of learning, attention and behaviour in relation to
changes in the standard EEG, especially in cartographic EEG and
NFB findings.
AB  - U radu se analiziraju promene pri preusmeravanju vizuelne i auditivne
informacije između hemisfera kod deteta sa sindromom hiperakrivnosti
i njihovi efekti koji mogu dovesti do boljeg angažovanja pažnje
pri analizi auditivne i vizuelne informacije. Metod je uključio upotrebu
kartografskog EEG-a u toku kliničke procedure kod desetogodišnjeg
dečaka sa poremećajem pažnje i sindromom hiperaktivnosti, koji je
imao theta disfunkciju manifestovanu na standardnom EEG-u. Kvantitativni
EEG profil je meren pomoću NihonKohden Corporation, EEG
– 1200K Neurofaxaparata, koji obezbeđuje 19 EEG kanala. Elektrode su
pozicionirane prema 10/20 Internacionalnom sistemu za pozicioniranje
elektroda. Impendanca je bila održavana ispod 5кΩ, sa ne više od 1кΩ
razlike između elektroda. Niži filter je bio postavljen na 0,53Hz i viši
filter na 35Hz. Snimanje je vršeno tokom mirnog perioda kao i tokom
stimulacije koja je uključivala osnove govora i jezika.
Standardni EEG i Neurofidbek (NFB) tretman su indikovali više
theta opterećenje, alpha 2 i beta 1 aktivnost, merene kartografskim
EEG-om, što je urađeno nakon relativnog neuspeha NFB tretmana.
Nakon ovoga, primenjen je NBF tretman u trajanju od šest meseci, na
način da kada dečak čita vizuelna informacija je prosleđivana levoj hemisferi,
a auditivna informacija ograničena na desnu hemisferu. Ponovljene
EEG mape su pokazale značajno poboljšanje na planu pažnje i na
planu ponašanja i učenja. U radu se diskutuje o određenim aspektima
učenja, pažnje i ponašanja u odnosu na promene na standardnom EEGu,
posebno kartografskom EEG-u i NFB saznanjima.

i njihovi efekti koji mogu dovesti do boljeg angažovanja pažnje
pri analizi auditivne i vizuelne informacije. Metod je uključio upotrebu
kartografskog EEG-a u toku kliničke procedure kod desetogodišnjeg
dečaka sa poremećajem pažnje i sindromom hiperaktivnosti, koji je
imao theta disfunkciju manifestovanu na standardnom EEG-u. Kvantitativni
EEG profil je meren pomoću NihonKohden Corporation, EEG
– 1200K Neurofaxaparata, koji obezbeđuje 19 EEG kanala. Elektrode su
pozicionirane prema 10/20 Internacionalnom sistemu za pozicioniranje
elektroda. Impendanca je bila održavana ispod 5кΩ, sa ne više od 1кΩ
razlike između elektroda. Niži filter je bio postavljen na 0,53Hz i viši
filter na 35Hz. Snimanje je vršeno tokom mirnog perioda kao i tokom
stimulacije koja je uključivala osnove govora i jezika.
Standardni EEG i Neurofidbek (NFB) tretman su indikovali više
theta opterećenje, alpha 2 i beta 1 aktivnost, merene kartografskim
EEG-om, što je urađeno nakon relativnog neuspeha NFB tretmana.
Nakon ovoga, primenjen je NBF tretman u trajanju od šest meseci, na
način da kada dečak čita vizuelna informacija je prosleđivana levoj hemisferi,
a auditivna informacija ograničena na desnu hemisferu. Ponovljene
EEG mape su pokazale značajno poboljšanje na planu pažnje i na
planu ponašanja i učenja. U radu se diskutuje o određenim aspektima
učenja, pažnje i ponašanja u odnosu na promene na standardnom EEGu,
posebno kartografskom EEG-u i NFB saznanjima.",

AB  - The current study is a preliminary examination of cognitive profiles and cortical distribution of the spectral power of different electroencephalogram (EEG) rhythms in children with specific language impairment and subclinical epileptiform discharges. Although a number of empirical studies point to higher incidence of abnormal EEGs in children with specific language impairment, only a few studies were found examining electrophysiological characteristics, such as locus of discharges and connections with cognitive functioning in this population of children. The sample included 12 children with specific language impairment (SLI) and abnormal EEG who underwent testing of cognitive functioning using the Wechsler Intelligence Scale for Children (WISC). The control sample included 13 children with specific language impairment and regular EEG. Results point to lower scores on several subtests of the performance scale for children with abnormal EEG than for the group with regular EEG. Detailed EEG analysis of cortical distribution of the spectral power of different EEG rhythms partially confirms the results of neuropsychological assessment, pointing to abnormal function of frontal and temporal regions. Higher values of spectral power of the delta brain rhythm in frontal regions are associated with lower results on the WISC performance scale. Results are discussed in the context of subgroups of the population of children with SLI.

AB  - Emotions play a significant role in fluency disorders. In this research we wanted to examine immediate and delayed verbal recall for auditory presented words that carry information about different emotional state (emotion-related words) and emotionally neutral words in children who stutter (N=35) and their peers (N=35). Using only word semantics, we wanted to eliminate emotional verbal expression of words as a factor that can influence memory abilities. In addition, we also wanted to examine skin conductance measure as an indicator of autonomic nervous system arousal during short-term memory task for emotion-related and emotionally neutral words. Parental questionnaire (Stuttering Intensity in Children Who Stutter in Positive and Negative Emotion-Related Everyday Situations) was given to parents of children who stutter in order to collect data regarding stuttering severity in emotionally arousing situations in everyday life. Differences between the experimental and the control group in global memory capacity are highest in immediate recall (p=0,01) with the tendency for lowering statistical significance with prolongation of retention interval. According to the questionnaire results, children who stutter show a higher degree of stuttering in situations with positive emotional valence (p lt  0.00). Skin conductance measurements showed higher autonomic nervous system arousal during perception and free recall of positive emotion-related words in children who stutter when compared to negative and emotionally neutral words. The results indicate higher emotional arousal to positive emotions in children who stutter (p=0.02), leading to either less fluent speech or suppression of verbal short-term memory capacity.

AB  - Numerous studies have used electrophysiological methods in
attempts to discriminate dyslexic from non-dyslexic readers and to
identify brain mechanisms underlying specific reading disability.
The aim of the present study is to apply an analysis of largescale
neuronal networks to study brain connectivity in children with
developmental dyslexia during silent reading and to compare results
with their peers.
EEG signal was recorded from five dyslexic and five normal
readers (three female and two male) using 10-20 International system
for electrode placement and mono-polar montage. Additional EOG
electrodes were used in order to register horizontal and vertical eye
movements. Subjects had a task to read a simple story silently. The
text was presented on a computer screen with 40 cm distance from
the subject’s eyes. Five-second artefact free periods were analysed
offline using spectral analysis (FFT algorithm). Amplitude correlations
in Theta rhythm (4-7 Hz) between all 19 electrodes were calculated.
Statistically significant correlations (p=0.01) were further used for
neural network modelling.We found that dyslexic children had one closed neural network
that consisted of four elements (centro-parietal cortex: C3-C4-
Cz-P4 electrodes) and three interhemispheric connections between
homologous electrodes without complex intra- and interhemispheric
connections. Non-dyslexic readers had far more, both quantitatively
and qualitatively, complex large-scale neuronal networks in frontotemporal
and centro-parietal cortex.
Complex cognitive functions, such as reading, require dynamic
collaboration between close and distant cortical regions in order to
achieve adequate connections for parallel information processing.
AB  - Brojne studije koristile su elektrofiziološke metode u pokušaju da
diferenciraju decu sa razvojnom disleksijom od tipičnih čitača kao i da
identifikuju mehanizme koji su u osnovi razvojne disleksije.
Cilj ove studije bio je da se ispitaju karakteristike povezivanja
moždanih regija u lokalne i široko-distribuirane neuralne mreže kod
dece sa razvojnom disleksijom tokom čitanja u sebi i da se rezultati
uporede sa rezultatima dece urednih čitača.
EEG signal je snimljen kod petoro dece sa razvojnom disleksijom
(2 dečaka i 3 devojčice) i pet urednih čitača iste polne i uzrasne strukture,
koristeći 10-20 Internacionalni sistem za pozicioniranje elektroda
uz monopolarnu montažu. Dodatne elektrode su korišćene kako
bi se registrovali pokreti očiju. Ispitanici su imali zadatak da u sebi
čitaju jednostavan tekst. Tekst je prezentovan na monitoru računara
na udaljenosti od 40cm od očiju ispitanika. Periodi od 5 sekundi bez
artefakata analizirani su spektralnom analizom (FFT-Fast Fourier
Transform algoritam). Statistički značajne (p<0.01) korelacije u amplitudi
teta ritma (4-7 Hz) između svih 19 elektroda korišćene su za dalje
modeliranje neuralnih mreža.
Ustanovljeno je da su deca sa razvojnom disleksijom formirala
jednu četvoročlanu neuralnu mrežu (centro-parijetalni korteks: C3-
C4-Cz-P4) kao i tri interhemisferne konekcije između homolognih
elektroda leve i desne hemisfere bez kompleksnih intra ili interhemisfernih
konekcija. Deca sa tipičnom funkcijom čitanja su ostvarila daleko
veći broj tročlanih, četvoročlanih i petočlanih zatvorenih mreža u
odnosu na decu sa razvojnom disleksijom. Kognitivna funkcija kao što je čitanje zahteva dinamičku saradnju bliskih i udaljenih kortikalnih
regiona u cilju postizanja paralelnog procesiranja informacije.

AB  - The EEG is a non-invasive method to obtain information about neural
activity associated with cognitive processes. Its great temporal resolution can
provide data regarding the process itself within milliseconds but EEG has
poor spatial resolution. The EEG is based on the voltage difference between
two (or more) electrodes and represents the summation of numerous neuron
activity.
The objective of the study reported was to analyze the EEG signal in verbal
information processing task using spectral analysis for frequency band and
power spectrum extraction. Also we wanted to determine relation between
different frequency bands (Theta – θ, Beta – β and Alpha - α) and their
power spectrum in different parts of the task (perception, retention and
reproduction) for different stimuli (syllables, words, non-words, sentences,
picture situations and picture stories).
The sample comprised of 9 subjects, right-handed, native speakers of Serbian
language with no history of hearing and speech-language disorders.
All subjects were not using any medication that may influence EEG signal.
After the standard procedure of EEG electrodes placement, subjects listened
to a set of auditory presented verbal stimuli. After each stimulus they
had a 2 second retention period time followed by a reproduction period.
They were given 5 seconds for viewing picture situations and a 15 second
period for the picture story followed by a reproduction period.
Differences between EEG frequency bands and power as well as their cortical
representation in verbal information processing task will be discussed.

abstract = "The EEG is a non-invasive method to obtain information about neural
activity associated with cognitive processes. Its great temporal resolution can
provide data regarding the process itself within milliseconds but EEG has
poor spatial resolution. The EEG is based on the voltage difference between
two (or more) electrodes and represents the summation of numerous neuron
activity.
The objective of the study reported was to analyze the EEG signal in verbal
information processing task using spectral analysis for frequency band and
power spectrum extraction. Also we wanted to determine relation between
different frequency bands (Theta – θ, Beta – β and Alpha - α) and their
power spectrum in different parts of the task (perception, retention and
reproduction) for different stimuli (syllables, words, non-words, sentences,
picture situations and picture stories).
The sample comprised of 9 subjects, right-handed, native speakers of Serbian
language with no history of hearing and speech-language disorders.
All subjects were not using any medication that may influence EEG signal.
After the standard procedure of EEG electrodes placement, subjects listened
