Background: Acceptable parental behaviors and practices toward a child vary across countries and may impact the risk of exposure to maltreatment. Conversely, prior experiences of maltreatment as a child may influence the acceptability of child maltreatment (CM) behaviors. Objective: This exploratory study examined the association between CM expe...

Background: Emotion regulation (ER) and emotion recognition (ERC) deficits are frequently observed in the sequelae of child maltreatment (CM). Despite a wealth of research on emotional functioning, these emotional processes are often presented as independent but related functions. As such, there is currently no theoretical framework on how differe...

Objective: Child maltreatment is often studied as a general category or individually as a subtype, but maltreatment subtypes are rarely studied simultaneously. Despite a breadth of research in the effects of child maltreatment on emotional competence, discrepant findings emerge when child maltreatment subtypes are explored. The present study aims t...

This retrospective study provides a preliminary analysis that distinguished depressed from nondepressed perpetrators of IPH from a sample of 135 cases a...

Sea urchin skeletons, or tests, comprise rigid calcareous plates, interlocked and sutured together with collagen fibres. The tests are malleable due to mutability in the collagen fibres that loosen during active feeding, yielding interplate gaps. We designed an extraterrestrial simulation experiment wherein we subjected actively growing sea urchins...
