Charting New Paths in the Study of Kin Term Acquisition

Topics in Cognitive Science, EarlyView.
Abstract Kin terms appear among infants’ earliest words, yet a full mastery of kin concepts typically emerges only in late childhood. This prolonged developmental trajectory reflects not only children's acquisition of an abstract relational system of words, but also their growing understanding of social relationships and interactional norms.

Mothers' responses to relational savoring as a function of attachment: A qualitative study

Infant Mental Health Journal: Infancy and Early Childhood, Volume 47, Issue 4, July 2026.
Abstract A person's state of mind with respect to attachment, measured by the Adult Attachment Interview (AAI), represents how the individual perceives, accesses, and processes attachment‐related content. One's state of mind with respect to attachment is thought to guide behavior in relationships, including caregiving relationships, and thus may have ...

Density‐dependent habitat selection in plains bison

The Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
Using GPS collar data, we tested whether habitat selection of plains bison in Grasslands National Park, Canada, was density dependent. Bison selected for areas of high vegetation productivity far from human activity when population density was low and increased use of lower productivity habitat closer to disturbance as density increased.

Clinical Endocrinology, Volume 105, Issue 1, Page 51-59, July 2026.
ABSTRACT Context Adult data indicate that hypogonadism is underdiagnosed and undertreated in Prader‐Willi Syndrome (PWS). Objectives We aimed to describe the spectrum of pubertal development, and the diagnosis and treatment of hypogonadism in paediatric/adolescent patients with PWS. Design/Patients A retrospective cohort study of patients with PWS aged
