Individual differences in word learning from print and digital shared book reading.

Area of Science:

• Child Development
• Educational Psychology
• Cognitive Science

Background:

• Shared book reading is crucial for children's vocabulary development.
• The impact of book format (print vs. digital) on word learning is not fully understood.
• Individual learner characteristics and their interaction with media format require further investigation.

Purpose of the Study:

• To investigate the effects of book format (print vs. digital) on children's word learning.
• To examine the influence of individual differences, including prior vocabulary knowledge and executive functions, on word learning.
• To explore potential interactions between book format and child characteristics in word acquisition.

Main Methods:

• A cross-sectional, within-subjects study involving 99 English-speaking caregiver-child dyads (children aged 4-5 years).
• Children participated in reading custom storybooks in both print and digital formats.
• Word learning was assessed using production, definition, and comprehension tests.

Main Results:

• No significant main effect of book format on overall word learning was found.
• Prior vocabulary knowledge strongly predicted performance across all word learning measures.
• Executive functions significantly predicted definition test performance, and an interaction with digital format was observed for comprehension.

Conclusions:

• Child characteristics, particularly prior vocabulary and executive functions, are more influential than book format alone in word learning.
• The digital book format showed a benefit for comprehension among children with higher executive functions.
• Future research should consider individual differences and diverse outcome measures when studying learning from print and digital media.
