Subclaims¶

q3 i2 In a MANOVA, parents uttered more unique spatial words with girls than boys (quality), with no quantity difference. → Farran 2025 q3 i2 The child-sex effect on spatial language quality remained after controlling for SES and parent talkativeness. → Farran 2025 (2)

Evidence¶

Farran 2025¶

Farran, E. K., Fink, E., Hughes, C., Gilligan-Lee, K. A., & The NewFAMS team. (2025). Limited sex differences in spatial language in parent-child dyads. Learning and Instruction, 95, 102006. https://doi.org/10.1016/j.learninstruc.2024.102006

q3 · i2 · associational · r2

MANOVA (N = 104) with parent spatial language quantity and quality as dependent variables, parent sex and timepoint within-subject, child sex between-subject. Quality showed a child-sex effect, "F (1, 102) = 4.68, p = .033, ηp2 = .044"; quantity did not (F < 1).

"Follow up ANOVAs demonstrated that the main effect of child sex was not significant for spatial language quantity (F < 1), but analysis of spatial language quality demonstrated that parents uttered more unique spatial words during block play with girls than with boys, F (1, 102) = 4.68, p = .033, ηp 2 = .044."

Farran 2025 (2)¶

Farran, E. K., Fink, E., Hughes, C., Gilligan-Lee, K. A., & The NewFAMS team. (2025). Limited sex differences in spatial language in parent-child dyads. Learning and Instruction, 95, 102006. https://doi.org/10.1016/j.learninstruc.2024.102006

q3 · i2 · associational · r2

MANCOVA controlling for family SES and parent total words showed the child-sex effect persisted for spatial language quality, "F (1, 100) = 7.87, p = .006, ηp2 = .073", but not quantity (F < 1); the timepoint effect became non-significant.

"the effect of child sex remained, Λ = .895, F(2, 99) = 5.83, p = .004, ηp 2 = .105 (spatial language quality: F (1, 100) = 7.87, p = .006, ηp 2 = .073; spatial language quantity: F < 1)."

Discussion¶

Related Claims¶

• Tentative longitudinal interaction: mother spatial language quantity at 24 months relates negatively to boys' but positively to girls' later spatial language quality — related
• Mothers and fathers show no difference in spatial language use with their children, and children produce similar spatial language with each parent — related
• Boys and girls show comparable spatial language use at 24 and 48 months during structured DUPLO play — related
• The authors interpret higher spatial language quality with daughters as possibly reflecting a perceived need to provide conceptual support — related
• Parent spatial language is concurrently associated with child spatial language at 48 months, explaining substantial variance beyond controls — related
• Parents used more spatial language at 24 months than at 48 months, an effect attributable to differences in overall talkativeness — related
