The Developing Visual Brain – from Newborns to Numeracy

Janette Atkinson & Oliver Braddick

Visual development forms the basis of social and cognitive development in the first years of life. We will illustrate some key developments with a short video.  We have tracked the development of visual abilities in infants and young children, to provide a unique window into the developing visual brain, both typical and atypical.  Our work has helped to establish the major transition from a largely subcortical visual brain system at birth to the characteristic mechanisms of cortical vision and their control over subcortical visual responses. We have developed novel infant-friendly tests, both cortical event- related potentials measures and behavioural,  to identify delays in visual development in the first year of life which are important for pattern, movement,  depth  perception , the cortical control of attention shifts and the timing of  the onset of visuomotor and visuo-cognitive milestones.  These measures have proved to be sensitive indicators of the effects of early brain injury and premature birth in predicting later neurocognitive outcomes..

Not all parts of the cortical visual system are equally vulnerable.  Tests of children’s sensitivity to global form and global motion ( coherence thresholds)  show that the global motion system, while starting to function early at around 2-3 months of age , is particularly impaired  in a wide range of developmental disorders, both genetic and acquired (in Williams Syndrome, autism, Fragile X, congenital cataract, hemiplegia, preterm birth).  This differential impairment has led us to the hypothesis of ‘dorsal stream vulnerability’ in which poor motion performance is associated with a cluster of attentional, spatial, and visuo-motor deficits.  Our recent work with a large cohort of 150 typically developing children in San Diego shows that individual differences in global motion sensitivity are associated with the brain growth in an area within parietal cortex around the intraparietal sulcus, which has been widely implicated as important part of the network used attentional control and  in numerosity judgements and mathematics. In addition, individual differences in motion sensitivity is associated with integrity of  a major white matter fibre tract linking parietal and frontal lobes, which has been implicated as an essential part of both parieto-frontal networks for attention   Consistent with this, children’s global motion, but not global form, performance, is correlated with measures of mathematical achievement and numerosity judgments.  We can speculate on how far-reaching these differences in early visual brain development really are, and what are the dynamics of alternative developmental trajectories.

am 13.10. und 20.10.

Anmeldung: Bitte per E-Mail an Natasha Reed, natasha.reed@uni-goettingen.de

Termine: jeweils 13.10.2017, 9:00 bis 13:00 Uhr oder  20.10.2017, 13:00 bis 17:00 Uhr

Dozentin: Natasha Reed

Das Seminar findet in einer halbtägigen Sitzung im Computerpool statt (Heinrich-Düker-Weg 12, Raum 0.481). Der Inhalt der beiden Sitzungen ist gleich.

Max. Teilnehmerzahl: 20

Das Seminar ist ausgerichtet auf Bachelor-Studierende der Psychologie und bietet Ihnen die Gelegenheit, Ihre früheren Kenntnisse der Literatursuche zu aktualisieren und ggf. zu erweitern. Das Ziel des Seminars ist es, Sie anhand praktischer Rechercheaufgaben darin zu unterstützen, Ihre Literatur-Suche zu optimieren und so erfolgreich wie möglich zu machen.

Um Sie bei der Vorbereitung eigener Projekte, Hausarbeiten und schließlich der Bachelorarbeit zu unterstützen, konzentriert sich das Seminar auf folgende Aspekte der Literatur-Suche:

1. die Nutzung verschiedener Quellen, z.B. Online-Kataloge der Universitätsbibliothek oder Online-Quellen wie ‚Google Scholar‘ und ‚Web of Knowledge‘
2. Hinweise auf die Quellen-Suche durch Nutzung von Schlüssel-Wörtern
3. Nutzung des Literaturverwaltungswerkzeugs ‚Citavi‘
4. Regeln des Zitierens und guter wissenschaftlicher Praxis
