Examining mindset and grit in concurrent and future reading comprehension: A twin study

Area of Science:

• Educational Psychology
• Developmental Psychology
• Behavioral Genetics

Background:

• Noncognitive factors like intelligence mindset and grit are increasingly targeted for academic achievement interventions.
• While their impact on general educational outcomes is established, their specific role in reading ability improvement remains under-researched.

Purpose of the Study:

• To investigate the relationship between intelligence mindset and grit with current, future, and changes in reading comprehension ability.
• To explore potential genetic and environmental influences on these relationships using a twin study design.

Main Methods:

• Utilized data from 422 twin pairs from the Florida Twin Project on Reading, Behavior and Environment.
• Assessed intelligence mindset and grit, alongside reading comprehension at two time points (ages 13 and 15).
• Employed twin modeling to analyze genetic and environmental influences.

Main Results:

• Weak to moderate positive correlations were observed between mindset, grit, and reading ability scores.
• Neither mindset nor grit demonstrated a significant relationship with the change in reading ability over time.
• Twin modeling indicated minimal shared genetic or environmental influences between mindset/grit and reading ability.

Conclusions:

• The study's findings do not support intelligence mindset or grit as mechanisms driving changes in reading comprehension ability.
• Current evidence suggests these noncognitive factors may not be effective intervention targets for improving reading skills.
