Introducing an adolescent cognitive maturity index.

Children show substantial variation in the rate of physical, cognitive, and social maturation as they traverse adolescence and enter adulthood. Differences in developmental paths are thought to underlie individual differences in later life outcomes, however, there remains a lack of consensus on the normative trajectory of cognitive maturation in adolescence. To address this problem, we derive a Cognitive Maturity Index (CMI), to estimate the difference between chronological and cognitive age predicted with latent factor estimates of inhibitory control, risky decision-making and emotional processing measured with standard neuropsychological instruments.

Empathic emotion regulation in prosocial behaviour and altruism.

Emotions evoked in response to others' distress are important for motivating concerned prosocial responses. But how emotion regulation shapes prosocial responding is not yet well understood. We tested the role of empathic emotion regulation in promoting prosocial motivation and costly donations across two studies, first in a community sample and then in a sample of altruistic kidney donors and a matched comparison sample.

Adolescent Emotional Control Moderates Benefits of a Multicomponent Intervention to Improve Type 1 Diabetes Adherence: A Pilot Randomized Controlled Trial.

Objective: We previously tested via randomized controlled trial a novel intervention for adolescents with type 1 diabetes and above-target glycemic control that combined web-delivered incentives for self-monitoring of blood glucose (SMBG) and brief web counseling with working memory training and parental contingency contracting training. Results showed improved SMBG and decreased glycosylated hemoglobin (HbA1c) at 6- and 12-month follow-ups. However, it has not been elucidated if improvements in SMBG mediated the immediate benefits of this treatment on HbA1c nor if this intensive intervention uniquely benefited a subgroup of adolescents with higher problems in emotional control.

Delay discounting associated with challenges to treatment adherence and glycemic control in young adults with type 1 diabetes.

Introduction: Many young adults with type 1 diabetes (T1D) face challenges in adherence to self-management practices and have above-target HbA1c. Poorer decision-making skills, indicated by greater delay discounting, may be linked to these factors.

Methods: An online survey using social media ads targeted young adults aged 18-26 with T1D.

Amygdala-midbrain connectivity indicates a role for the mammalian parental care system in human altruism.

Costly altruism benefitting a stranger is a rare but evolutionarily conserved phenomenon. This behaviour may be supported by limbic and midbrain circuitry that supports mammalian caregiving. In rodents, reciprocal connections between the amygdala and the midbrain periaqueductal grey (PAG) are critical for generating protective responses toward vulnerable and distressed offspring.
