Infants’ attention to the mouth is thought to support language acquisition, yet this relation has been scantly tested longitudinally. This study assessed attention to the mouth and the eyes at 5.5 (n= 91; Polish, 49% females) and 11 months, between time-point changes, and their associations with language development in infancy (11 months) and toddl...

Infants’ limb movements evolve from disorganized to more selectively coordinated during the first year of life as they learn to navigate and interact with an ever-changing environment more efficiently. However, how these coordination patterns change during the first year of life and across different contexts is unknown. Here, we used wearable motio...

Visual search guides goal-directed action in humans and many other species, and it has been studied extensively in the past. Yet, no study has investigated the relative contributions of genes and environments to individual differences in visual search performance, or to which extent etiologies are shared with broader cognitive phenotypes. To addres...

Exploring unknown quantum systems is an experimental challenge. Recent proposals exploring quantum gravity have suggested circumventing this problem by considering the unknown system as a mediator between two known systems. If such a mediation can locally generate entanglement in the known systems, then the mediator must be non-classical. The same...
Preprint
Recent proposals in quantum gravity have suggested that unknown systems can mediate entanglement between two known quantum systems, if and only if the mediator itself is non-classical. This approach may be applicable to the brain, where speculations about quantum operations in consciousness and cognition have a long history. Proton spins of bulk wa...

In the 1st year of life, infants gradually gain the ability to control their eye movements and explore visual scenes, which support their learning and emerging cognitive skills. These gains include domain-general skills such as rapid orienting or attention disengagement as well as domain-specific ones such as increased sensitivity to social stimuli...
Conference Paper
Recent progress in the study of infant motor development has been achieved by ground-breaking paradigm shifts combined with clever and innovative tasks that place the infant center stage as the acting subject. One of the challenges that developmental scientists are facing today is understanding the complexity of infants’ spontaneous movements. Nove...

Efficient visual exploration in infancy is essential for cognitive and language development. It allows infants to participate in social interactions by attending to faces and learning about objects of interest. Visual scanning of scenes depends on a number of factors and early differences in efficiency are likely contributing to differences in lear...

In social animals, studying interactions with conspecifics is crucial for understanding even basic physiological, behavioral and cognitive processes. Due to a visible ‘ecological turn’ in behavioral research we observe a rapid development of novel methods devoted to studying interaction. In this paper, we offer a case study of an animal interactive...

There are multiple magnet resonance imaging (MRI) based approaches to studying the ageing brain. Getting older affects both the structure of the brain and our cognitive capabilities, but there is still no solid evidence on how ageing influences the mechanisms underlying the MRI signal. Here, we apply a zero-spin echoes (ZSEs) weighted MRI sequence...

Multiple visual attention mechanisms are active already in infancy, most notably one supporting orienting towards stimuli and another, maintaining appropriate levels of alertness, when exploring the environment. They are thought to depend on separate brain networks, but their effects are difficult to isolate in existing behavioural paradigms. Bette...

Autism spectrum disorder (ASD) is commonly conceived as the extreme end of a continuum. Research suggests that autistic individuals outperform typically developing controls in visual search. Thus, enhanced visual search may represent an adaptive trait associated with ASD. Here, using a large general population sample (N = 608, aged 9–14 years), we...

Standard looking-duration measures in eye-tracking data provide only general quantitative indices, while details of the spatiotemporal structuring of fixation sequences are lost. To overcome this, various tools have been developed to measure the dynamics of fixations. However, these analyses are only useful when stimuli have high perceptual similar...

That consciousness could have its' basis in quantum computing has been speculated for many years. Unfortunately, unitary quantum gates, the main ingredient of quantum computing, are not compatible with irreversible biological systems which are effectively non-unitary. That is why Penrose and Hameroff have suggested and Hagan et al. have theoretical...

The analysis of parent-child interactions is crucial for the understanding of early human development. Manual coding of interactions is a time-consuming task, which is a limitation in many projects. This becomes especially demanding if a frame-by-frame categorization of movement needs to be achieved. To overcome this, we present a computational app...

Conference Paper
Objectives Intermolecular multiple quantum coherence (iMQC) [1] is a physical phenomenon based on dipolar interaction correlation distances, which have the potential to reveal information from tissue dynamics beyond flow and diffusion. A breakthrough of this fascinating contrast mechanism is mainly hindered by its low signal-to-noise ratio [2]. Her...

Here, we want to study how structural changes may affect the tissue pulsation which is related to blood circulation. We used a new method that allows to measure the sudden change of intracellular water concentration evoked by the cardiac pressure wave . An alteration in blood circulation of depressed patients should change the pressure but also the...

Question
In our lab we are looking for using head mounted eye trackers in infants between 5 months and 2 years of age. I think you are using those models from pupil labs and we are interesting in this particular models as well.  My question is, since these are 3D mounted, how did you design the model?

Use new analysis methods to study complexity of eye movements that can shed more light on infants visual foraging strategies.
Project
From birth, humans pay special attention to faces and human voice and our brains seem especially attuned to rapidly learn about these aspects of interacting humans from early. Our daily experience of other people is typically multisensory, yet, over the last few decades research on language and communication development in infancy, including phonological development, was focused primarily on speech as an auditory phenomenon. The idea that visual information about speech may play an important role in shaping infant knowledge of speech sounds has only recently attracted more attention. New research on perception of audiovisual speech (speaking faces) showed the importance of visual speech information (mouth movements) for the infant’s phonological knowledge as well as language comprehension and production throughout subsequent years of life. There is growing evidence that in the human brain representations of speech may be inherently multimodal in nature and that they include visual speech cues, while key parts of the “social brain” network, such as posterior part of the superior temporal sulcus integrate visual information about faces with visual and auditory speech information. In the project we employ new models of integration of speech and face processing in the adult brain to better understand the development of visual and audiovisual speech processing in infancy, between the ages of 5.5 and 10 months. A period of rapid changes in face and speech perception, it involves the narrowing of perceptual skills to native language speech sounds and faces of own species. In our project we will investigate whether these perceptual changes are related to the integration of neural pathways for face and speech processing. In particular, we will investigate the changes in temporal cortex sensitivity to visual and audiovisual speech, as well as probe the association between neural mechanisms for audiovisual speech processing and for configural face processing.
