“…It is important to note that the interpretation of the duration of looking time varies throughout the first year of development. During the first few months of infancy, longer looking time is described as 'sticky fixation' (Kulke et al 2017), a reflection of the difficulty that young infants have disengaging their attention from stimuli. After approximately 4 months, as disengagement emerges and infants are increasingly able to shift their attention, shorter looking times under certain conditions (e.g.…”

“…However, by 6 months, typically developing (TD) infants are generally able to shift their gaze between competing stimuli flexibly (Hood and Atkinson 1993). This new capacity is considered to be a reflection of the maturation of neural pathways that support visual attention regulation (Kulke et al 2017). The development of attention shifting has been of interest in neurodevelopmental disorders, as more pronounced latencies to disengage from a visual stimulus have been shown to predict maladaptive outcomes (Elsabbagh et al 2013).…”

Background While delays in cognitive development are detectable during early development in Down syndrome, the neuropsychological and biomedical underpinnings of cognitive skill acquisition in this population remain poorly understood. Method To explore this issue, 38 infants with Down syndrome [mean chronological age = 9.65 months; SD = 3.64] completed the Bayley Scales of Infant Development‐III and a set of laboratory tasks that measured sustained attention (duration of visual attention during a 1‐min object exploration task), attention shifting (mean latency to shift attention on an alternating object presentation task) and visual short‐term memory (dishabituation to a novel object on a change preference task). Results Latency to shift attention was negatively associated with Bayley Cognitive Scale raw scores, even when controlling for the effects of chronological age, r (33) = −.41, P = .02. In addition, prematurity status was associated with latency to shift attention. Conclusions Early attention shifting may be an important factor that facilitates overall cognitive skill acquisition in infants with Down syndrome, and premature birth may be a risk factor for difficulties on this dimension.

“…These have measured the latency of the fixation shift with an eye tracker, combined with a multielectrode geodesic net to carry out simultaneous EEG recording. This allows for an accurate measure of the latency of the saccadic shift of attention, and a simultaneous EEG recording from areas of cortex activated in making the attention shift before the eye movement itself (Kulke, Atkinson, & Braddick, 2017). …”

Research in the Visual Development Unit on “dorsal stream vulnerability' (DSV) arose from research in two somewhat different areas. In the first, using cortical milestones for local and global processing from our neurobiological model, we identified cerebral visual impairment in infants in the first year of life. In the second, using photo/videorefraction in population refractive screening programs, we showed that infant spectacle wear could reduce the incidence of strabismus and amblyopia, but many preschool children, who had been significantly hyperopic earlier, showed visuo-motor and attentional deficits. This led us to compare developing dorsal and ventral streams, using sensitivity to global motion and form as signatures, finding deficits in motion sensitivity relative to form in children with Williams syndrome, or perinatal brain injury in hemiplegia or preterm birth. Later research showed that this “DSV” was common across many disorders, both genetic and acquired, from autism to amblyopia. Here, we extend DSV to be a cluster of problems, common to many disorders, including poor motion sensitivity, visuo-motor spatial integration for planning actions, attention, and number skills. In current research, we find that individual differences in motion coherence sensitivity in typically developing children are correlated with MRI measures of area variations in parietal lobe, fractional anisotropy (from TBSS) of the superior longitudinal fasciculus, and performance on tasks of mathematics and visuo-motor integration. These findings suggest that individual differences in motion sensitivity reflect decision making and attentional control rather than integration in MT/V5 or V3A. Its neural underpinnings may be related to Duncan's “multiple-demand” (MD) system.

“…The aim of this first part was to model the effect of eye-movements on EEG data. The eye movement was considered as a rectangular signal with a width of 0.7 s, the fixation duration used in several gaze-contingent studies (Kulke, 2019;Kulke et al, 2016aKulke et al, , 2016b, to model how it can lead to potential filter artefacts. When a high-pass filter (e.g.…”

“…Alternatively, stimulus onset related eyemovement artefacts can be avoided by extracting only short intervals (180 ms), so that most eyemovements occur after the extracted time window (Kulke, 2019;Kulke et al, 2015Kulke et al, , 2016aKulke et al, , 2016bKulke, Atkinson, & Braddick, 2020). However, guides to EEG methods recommend digital filters to be applied to the EEG data before these time windows are extracted to avoid edge artefacts (e.g.…”

Co-registration of electroencephalography (EEG) and eye movements is becoming increasingly popular, as technology advances. This new method has several advantages, including the possibility of testing non-verbal populations and infants. However, eye movements can create artefacts in EEG data. Previous methods to remove eye-movement artefacts, have used high-pass filters before data processing. However, the role of filter settings for eye-artefact exclusion has not directly been investigated. The current study examined the effect of filter settings on EEG recorded in a dataset containing task-relevant eye movements. Part 1 models the effects of filters on eye-movement artifacts and part 2 demonstrates this effect on an EEG dataset containing task-relevant eyemovements. It shows that high-pass filters can lead to significant distortions and create artificial responses that are unrelated to the target. In conclusion, high-pass filter settings of 0.1 or lower can be recommended for EEG studies involving task-relevant eye movements.
