Different Attentional and Memory Processes When Learning From a Peer or an Adult in Children

Infant and Child Development, Volume 35, Issue 5, September/October 2026.
ABSTRACT Both adult–child and child–child interactions support learning, yet it remains unclear whether children engage distinct cognitive strategies depending on the social context. In this study, 62 children aged 6–12 years, tested in Switzerland, completed a memory task in which novel objects were introduced by either a child or an adult speaker ...

Lack of Hydraulic Acclimation in Response to Multiple Droughts and Recovery

Plant, Cell &Environment, Volume 49, Issue 9, Page 6931-6943, September 2026.
ABSTRACT Human‐caused climate change is expected to bring more frequent and extended droughts with shorter wet periods of relief in between for many regions of the world. Critical knowledge gaps remain around the extent to which tree species can acclimate physiologically to repeated droughts.
