Lipreading, the ability to understand speech by observing lips and facial movements, is a vital communication skill that enhances speech comprehension in diverse contexts, such as noisy environments. This study examines the neural mechanisms underlying lipreading in the Polish-speaking population, focusing on the complexity of linguistic material a...

Statistical learning is the cognitive ability to rapidly identify structure and meaning in unfamiliar streams of sensory experience, even in the absence of feedback. Despite extensive studies, the neurocognitive mechanisms underlying this phenomenon still require further clarification under varying cognitive conditions. Here, we examined neural mec...

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder hallmarked by challenges in social communication, limited interests, and repetitive, stereotyped movements and behaviors. Numerous research efforts have indicated that individuals with ASD exhibit distinct brain connectivity patterns compared to control groups. However, these investiga...

Background Developmental language disorder (DLD) is an impairment that disturbs the ability to acquire and make use of native language. The exact cognitive and neuronal brain underpinnings of the disorder are still a matter of investigation. Material and methods The relationship between the audiovisual phonemic short-term memory and particular lan...

Wprowadzenie Specyficzne zaburzenie językowe (SLI) oznacza zaburzenie rozwojowe charakteryzujące się ilościowymi i jakościowymi upośledzeniami językowymi, które odnoszą się do produkcji i/lub rozumienia języka ojczystego. W artykule przedstawiono wyniki diagnozy psychologicznej sześciorga dzieci z zaburzeniami rozwoju językowego w wieku 9–12 lat. D...

Converging lines of evidence seem to indicate reduced self‐referential processing in individuals with autism spectrum disorder (ASD). However, processing of one's own face has rarely been investigated in the context of ASD. Thus, the aim of the present study was to elucidate the role of attentional biases in the processing of self‐ and other faces...

Introduction: Working shifts has a negative impact on employee health and cognitive efficiency. The purpose of the study was to investigate the impact of shift work on cognitive functions - attention and working memory - using both behavioural and electrophysiological measures. Materials and method: The study was carried out on a group of 34 shift...

Previous studies indicate that autobiographical memory is impaired in individuals with autism spectrum disorder (ASD). Successful recollection of information referring to one’s own person requires the intact ability to re-activate representation of the past self. In the current fMRI study we investigated process of conscious reflection on the prese...

The ability to "read" the information about facial identity, expressed emotions, and intentions is crucial for non-verbal social interaction. Neuroimaging and clinical studies consequently link face perception with fusiform gyrus (FG) and occipital face area (OFA) activity. Here we investigated face processing in an adult, patient PK, diagnosed wit...

Background Impaired orienting to social stimuli is one of the core early symptoms of autism spectrum disorder (ASD). However, in contrast to faces, name processing has rarely been studied in individuals with ASD. Here, we investigated brain activity and functional connectivity associated with recognition of names in the high-functioning ASD group a...

One’s own name seems to have a special status in the processing of incoming information. In event-related potential (ERP) studies this preferential status has mainly been associated with higher P300 to one’s own name than to other names. Some studies showed preferential responses to own name even for earlier ERP components. However, instead of just...

Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental condition clinically characterized by social interaction and communication difficulties. To date, the majority of research efforts have focused on brain mechanisms underlying the deficits in interpersonal social cognition associated with ASD. Recent empirical and theoretical work...
