Journal ArticleDOI
The Other-Race Effect Develops During Infancy Evidence of Perceptual Narrowing
TL;DR: The findings suggest that facial input from the infant's visual environment is crucial for shaping the face-processing system early in infancy, resulting in differential recognition accuracy for faces of different races in adulthood.
Journal ArticleDOI
Three-month-olds, but not newborns, prefer own-race faces
David J. Kelly,Paul C. Quinn,Alan Slater,Kang Lee,Alan Gibson,M. Smith,Liezhong Ge,Olivier Pascalis +7 more
TL;DR: Newborns and young infants and 3-month-old infants tested for sensitivity to ethnicity using a visual preference paradigm suggest preferential selectivity based on ethnic differences is not present in the first days of life, but is learned within the first 3 months of life.
Journal ArticleDOI
Plasticity of face processing in infancy
Olivier Pascalis,Lisa S. Scott,David J. Kelly,Robert W. Shannon,Ellen Colton Nicholson,Michael J. Coleman,Charles A. Nelson +6 more
TL;DR: Exposure to non-native faces, in this case, faces of Barbary macaques, facilitates the discrimination of monkey faces, an ability that is otherwise lost around 9 months of age, and these data support, and further elucidate, the role of early experience in the development of face processing.
Journal ArticleDOI
Iron acquisition and virulence in Helicobacter pylori: a major role for FeoB, a high-affinity ferrous iron transporter.
Jyoti Velayudhan,Nicky J. Hughes,Andrew A. McColm,Julie A. Bagshaw,Chris L. Clayton,Simon C. Andrews,David J. Kelly +6 more
TL;DR: The results are consistent with FeoB‐mediated Fe2+ uptake being a major pathway for H. pylori Fe acquisition in the low‐pH, low‐O2 environment of the stomach.
Journal ArticleDOI
Genome-wide association study identifies vitamin B5 biosynthesis as a host specificity factor in Campylobacter
Samuel K. Sheppard,Xavier Didelot,Guillaume Méric,Alicia Torralbo,Keith A. Jolley,David J. Kelly,Stephen D. Bentley,Stephen D. Bentley,Martin C. J. Maiden,Julian Parkhill,Daniel Falush +10 more
TL;DR: It is found that isolates from cattle were better able to grow in vitamin B5-depleted media and it is proposed that this difference may be an adaptation to host diet.
