In the 21st century, advanced technologies such as virtual reality (VR) and augmented reality (AR) solutions have found their way to a variety of industrial applications and settings. The nuclear domain does not make an exception, and thus there has been an increasing interest to investigate how these technologies could be of use in different opera...
Conference Paper
According to some estimates, a majority of the accidents in the nuclear domain have been associated with failures in the use of procedures. A traditional model of procedure design and usage is based on the idea that because procedures represent the best understanding people have of the way their work has to be conducted, safety results from operato...

Dyslexic and control first-grade school children were compared in a Symbol-to-Sound matching test based on a non-linguistic audiovisual training which is known to have a remediating effect on dyslexia. Visual symbol patterns had to be matched with predicted sound patterns. Sounds incongruent with the corresponding visual symbol (thus not matching t...
Article
The recent fast multi-feature mismatch negativity (MMN) paradigms rest on the assumption that the deviant stimuli, alternating with the standard tone, strengthen the memory trace of the standard in respect to those attributes they have in common. In the present study, we tested whether the MMN can be recorded even without the standard stimulus, wit...
Article
In this study, we addressed whether a new fast multi-feature mismatch negativity (MMN) paradigm can be used for determining the central auditory discrimination accuracy for several acoustic and phonetic changes in speech sounds. We recorded the MMNs in the multi-feature paradigm to changes in syllable intensity, frequency, and vowel length, as well...
Article
A linguistic multi-feature mismatch negativity (MMN) paradigm with five types of changes (vowel, vowel-duration, consonant, frequency (F0), and intensity) in Finnish syllables was used to determine speech-sound discrimination in 17 normally-developing 6-year-old children. The MMNs for vowel and vowel-duration were also recorded in an oddball condit...
Article
Mismatch responses are elicited to changes in sound streams in healthy newborns. In the ideal case, these responses can predict cognitive problems later in life. We employed a multiple deviant paradigm for a fast assessment of the ability of the newborn brain to respond to various types of acoustic changes. In 12 healthy newborns, we recorded an el...

We studied the relationship between sleep quality and quantity and subsequently recorded automatically evoked event-related potential (ERP) responses. In previous studies decrement of attentional processing has been associated with changes in sleep. Sleep is shown to associate also with ERPs elicited by unattended sound stream, however, there is no...
Article
Full-text available
Recent studies have shown that the mismatch negativity (MMN), a change-specific component of the event-related potential (ERP), for particular auditory features is degraded in different clinical populations. This suggests that the MMN could, in principle, reflect the whole profile and extent of the central auditory deficit. In the present article,...
