Self-Generated Variability in Object Images Predicts Vocabulary Growth
Slone, Lauren K.; Smith, Linda B.; Yu, Chen
Developmental Science, v22 n6 e12816 Nov 2019
Object names are a major component of early vocabularies and learning object names depends on being able to visually recognize objects in the world. However, the fundamental visual challenge of the moment-to-moment variations in object appearances that learners must resolve has received little attention in word learning research. Here we provide the first evidence that image-level object variability matters and may be the link that connects infant object manipulation to vocabulary development. Using head-mounted eye tracking, the present study objectively measured individual differences in the moment-to-moment variability of visual instances of the same object, from infants' first-person views. Infants who generated more variable visual object images through manual object manipulation at 15 months of age experienced greater vocabulary growth over the next six months. Elucidating infants' everyday visual experiences with objects may constitute a crucial missing link in our understanding of the developmental trajectory of object name learning.
