Evidence for a Low Number Prior in Children's Intuitive Number Sense
Peer reviewed Peer reviewed

Miranda N. Long; Darko Odic – Child Development, 2025
Children rely on their Approximate Number System to intuitively perceive number. Such adaptations often exhibit sensitivity to real-world statistics. This study investigates a potential manifestation of the ANS's sensitivity to real-world statistics: a negative power-law distribution of objects in natural scenes should be reflected in children's…

Mix, Kelly S.; Bower, Corinne A.; Hancock, Gregory R.; Yuan, Lei; Smith, Linda B. – Child Development, 2022
Place value concepts were measured longitudinally from kindergarten (2017) to first grade (2018) in a diverse sample (n = 279; M[subscript age] = 5.76 years, SD = 0.55; 135 females; 41% Black, 38% White, 8% Asian, 12% Latino). Children completed three syntactic tasks that required an explicit understanding of base-10 symbols and three approximate…

Number-Concept Acquisition and General Vocabulary Development
Peer reviewed Peer reviewed
Direct linkDirect link
Negen, James; Sarnecka, Barbara W. – Child Development, 2012
How is number-concept acquisition related to overall language development? Experiments 1 and 2 measured number-word knowledge and general vocabulary in a total of 59 children, ages 30-60 months. A strong correlation was found between number-word knowledge and vocabulary, independent of the child's age, contrary to previous results (D. Ansari et…

How 15 Hundred Is like 15 Cherries: Effect of Progressive Alignment on Representational Changes in Numerical Cognition
Peer reviewed Peer reviewed

Thompson, Clarissa A.; Opfer, John E. – Child Development, 2010
How does understanding the decimal system change with age and experience? Second, third, sixth graders, and adults (Experiment 1: N = 96, mean ages = 7.9, 9.23, 12.06, and 19.96 years, respectively) made number line estimates across 3 scales (0-1,000, 0-10,000, and 0-100,000). Generation of linear estimates increased with age but decreased with…

In Defense of Qualitative Changes in Development
Peer reviewed Peer reviewed
Direct linkDirect link
Kagan, Jerome – Child Development, 2008
The balance between the preservation of early cognitive functions and serious transformations on these functions shifts across time. Piaget's writings, which favored transformations, are being replaced by writings that emphasize continuities between select cognitive functions of infants and older children. The claim that young infants possess…

Is 27 a Big Number? Correlational and Causal Connections among Numerical Categorization, Number Line Estimation, and Numerical Magnitude Comparison
Peer reviewed Peer reviewed
Direct linkDirect link
Laski, Elida V.; Siegler, Robert S. – Child Development, 2007
This study examined the generality of the logarithmic to linear transition in children's representations of numerical magnitudes and the role of subjective categorization of numbers in the acquisition of more advanced understanding. Experiment 1 (49 girls and 41 boys, ages 5-8 years) suggested parallel transitions from kindergarten to second grade…
