Biathlon shooting is one of the most cru cial aspects that determines an athlete's success. Several factors can affect shoot ing performance. This research was aimed at studying a range of eye and head movement parameters in biathletes of different skill levels as well as in novices in order to identify the most rel evant and differentiating ones that sepa rate novices from professionals. Eye and head movement parameters were recorded with a Pupil Labs Invisible (PI) infrared video recording eye track er. Recorded frequency is up 200 Hz, additive error in location determination is up to 5 deg, according the documenta tion. The study revealed significant dif ferences in visual motor control parame ters between elite biathletes, sub elite biathletes (with Candidate Master of Sports levels of proficiency) and novices. Elite biathletes show: a minimal gaze path length after shooting, indicat ing strong fixation on the target, which enhances accuracy; lower pre shooting head and gaze velocities and a reduced movement range, demonstrating strong gaze stabilization; a significantly smaller normalized ellipse square, indicating focused concentration with minimal excessive movements; and longer (twice as long as novices) and fewer fixations, with a high QIVT ratio (0.93 vs. 0.51 for novices), reflecting efficient attention allocation. Professionals blink less, cor relating with improved concentration and reduced cognitive load during criti cal tasks, alongside shorter shooting durations. The data obtained can be used to design personalized training pro grams aimed at enhancing gaze stability and reducing cognitive load.

Embodied and embedded cognition (EEC) theory proposes that language and cognitive development emerge from bodily interactions with the environment, yet empirical tests of this claim in clinical developmental populations remain rare. This mini-review synthesizes behavioral, electrophysiological, and structural neuroimaging evidence from children with serious early motor disorders—obstetric brachial plexus palsy and arthrogryposis multiplex congenita—which restrict ...

Anxiety is a multidimensional construct that influences cognitive performance in complex ways, yet its factor structure and domain-specific effects remain unclear. This study examined (1) the psychometric structure of general and specific anxiety measures, (2) their associations with cognitive performance across different domains, and (3) the predictive power of machine learning models in classifying cognitive ...

We provide examples of smooth three-dimensional Fano complete intersections of degree 2, 4, 6, and 8 that have absolute coregularity 0. Considering the main theorem of Avilov, Loginov, and Przyjalkowski (CNTP 18:506–577, 2024) on the remaining 101 families of smooth Fano threefolds, our result implies that each family of smooth Fano threefolds has an element of absolute ...

In psychology, people's assessment of conditional statements "if--then", agreement and disagreement with them is actively studied. This assessment of people who are not specialists in the field of logic often differs greatly from its requirements, especially if the reality observed by a person to one degree or another contradicts a formally correct logical conclusion. In ...

We show that bifurcations of four-dimensional symplectic diffeomorphisms with a quadratic homoclinic tangency to a saddle periodic orbit with real multipliers produce 2-elliptic periodic orbits if the tangency is not partially hyperbolic. We show that a normal form for the rescaled first-return maps near such tangency is given by a four-dimensional symplectic H´enonlike map and study bifurcations of the ...

We develop a machine-learning approach to reproduce the behavior of two versions of the van der Pol oscillator exhibiting a subcritical Andronov–Hopf bifurcation, with or without a codimension-2 Bautin point. We construct a neural-network model that functions as a recur rent map and train it on short segments of oscillator trajectories. The results show that, ...

It is known that for every continuous real-valued
function $f$ on the circle $\mathbb T=\mathbb R/2\pi\mathbb Z$ there exists a
change of variable, i.e., a self-homeomorphism $h$ of $\mathbb T$, such that
the superposition $f\circ h$ is in the Sobolev space $W_2^{1/2}(\mathbb T)$.
We obtain new results on simultaneous improvement of functions by a single

Dyslexia, a common learning disability, requires an early diagnosis. However, current screening tests are very time- and resourceconsuming. We present an LSTM that aims to automatically classify dyslexia based on eye movements recorded during natural reading combined with basic demographic information and linguistic features. The proposed model reaches an AUC of 0.93 and outperforms the ...

Cognitive flexibility (CF) allows individuals to adapt their behavior to changing environmental demands. As task complexity increases, CF may substantially impact performance by facilitating a shift towards more efficient information processing strategies. However, its role in tasks with high cognitive demands remains largely unexplored. Furthermore, while CF is associated with inhibitory control and working memory ...

Success in biathlon depends on physical fitness, psychophysiological parameters, and biomechanics. Key aspects include the speed and accuracy of shooting, which affect body oscillations and the stability of the "body-rifle" system. The level of stress, environmental conditions, and ski preparation are also important. This study is aimed to provide a thorough theoretical analysis of the ...

Background: Early recognition of autoaggressive tendencies in young people is essential for diagnostic screening and reducing suicidality risks. This can be achieved through psycholinguistic approaches such as corpus analysis and eye-tracking studies. Corpus research helps to develop generalized speech patterns of those at risk of suicide, while oculographic methods examine perceptual cues linked to suicidal ...

Cognitive flexibility is crucial for adapting behavior to shifting demands, particularly in tasks with varying cognitive requirements. This study examines the relationship between cognitive flexibility levels and eye movement parameters across six difficulty levels. Results show that highly flexible individuals consistently outperform those with lower flexibility, demonstrating more fixations, shorter fixation durations, and reduced blinking. ...

Valence plays a significant role in communication, influencing the perception, processing, and retention of verbal stimuli. Research in cognitive linguistics indicates that the emotional tone of verbal stimuli affects cognitive processing and reading behavior. For example, words with strong valence — both positive and negative — increase visual attention, as reflected in longer fixation durations. ...
