The subjective value of genuine smiles guides real-world social behaviour.

The mechanisms that underpin human social behaviour are poorly understood, in part because natural social behaviour is challenging to study. The task of linking the mechanisms thought to drive social behaviour to specific social behaviours in a manner that maintains ecological validity poses an even greater challenge. Here we report evidence that the subjective value people assign to genuine smiles, as measured in the laboratory, determines their responsiveness to genuine smiles encountered in a naturalistic social interaction.

Translating core intervention strategies into action: Interpersonal validation among self-injuring adolescents and their mothers.

Introduction: Most evidence-supported treatments for psychiatric problems teach clients skills to incorporate into their daily lives. Yet little research rigorously examines the extent to which individuals absorb these strategies and can competently apply them outside of the therapeutic relationship.

Objectives: The current study examined the degree to which self-injuring adolescents and their mothers (n = 30 dyads) and typical control mother-daughter dyads (n = 30) were able to utilize a multicomponent interpersonal validation-oriented skill from dialectical behavior therapy, after a single teaching.

Do measures of country-level safety predict individual-level health outcomes?

Unlabelled: Health is not only a result of biological conditions, but of psychological, economic, and social circumstances. Both proximal factors, which impact daily life, and distal factors, which are further removed from everyday life, can influence a person's wellbeing. However, traditionally these distal factors have been overlooked in public discourse and government policy.
