q3 i? In a linear regression with age and gender as predictors controlling for condition, neither factor was significant. → Kidd 2013

Evidence¶

Kidd 2013¶

Kidd, C., Palmeri, H., & Aslin, R. N. (2013). Rational snacking: Young children's decision-making on the marshmallow task is moderated by beliefs about environmental reliability. Cognition, 126(1), 109-114. https://doi.org/10.1016/j.cognition.2012.08.004

q3 · i? · causal · r2

Secondary regression analysis of the 28-child experiment testing age and gender as predictors of wait-time while controlling for condition. Age: β = 8.57, t = 1.29, p > 0.20; gender: β = −11.63, t = −0.10, p > 0.92. No standardized effect size is printed, so impact is null.

"Additionally, we performed a linear regression with age and gender as predictors, controlling for condition. Neither factor—age (β = 8.57, t = 1.29, p > 0.20) nor gender (β = −11.63, t = −0.10, p > 0.92)—was significant in our sample."

• Children in the reliable condition waited significantly longer on the marshmallow task than children in the unreliable condition (p < 0.0005) — related
• Children in the reliable condition were significantly more likely to wait the full 15 min than children in the unreliable condition (64.3% vs 7.1%) — related
• Early ability to delay gratification predicts later academic and social outcomes, but the association is weaker and more context-dependent than originally reported. — related
• Children's wait-times on sustained delay-of-gratification tasks reflect beliefs about environmental reliability in addition to self-control capacity — related
• Mood-related measures (contentedness, smiling, fidgetiness) did not vary systematically across the reliable and unreliable conditions — related
