Human infants seem to make positive social inferences about individuals who imitate others. In three preregistered experiments we test if these inferences include an expectation that imitators will be helpful, and also ask if the inferences infants make are about imitators' dispositions or primarily about their relationships. In each experiment 8- to 9-month-old infants saw one individual imitate, and another individual not imitate, the same target social partner.

Evaluating whether someone's behavior is praiseworthy or blameworthy is a fundamental human trait. A seminal study by Hamlin and colleagues in 2007 suggested that the ability to form social evaluations based on third-party interactions emerges within the first year of life: infants preferred a character who helped, over hindered, another who tried but failed to climb a hill. This sparked a new line of inquiry into the origins of social evaluations; however, replication attempts have yielded mixed results.

Women and racial and ethnic minorities have historically been underrepresented in medicine, making up a minority of all physicians and a smaller subset of plastic surgeons. Furthermore, these groups represent an even smaller fraction of plastic surgeons in research and leadership roles. Parallel to the general recognition of the importance of increasing diversity in the medical field, there has been a surge in the literature detailing current issues and highlighting potential areas for intervention within plastic surgery.

Research indicates young individuals with traumatic brain injuries (TBI) in juvenile justice settings lack essential support, mainly due to staff members' insufficient knowledge and skills in TBI-related areas stemming from a lack of relevant professional development. This study aimed to improve services for justice-involved youths with TBI in juvenile correction facilities by establishing empirically validated core competencies tailored to their needs. Through a Delphi study involving experts in juvenile services, juvenile corrections, TBI, transition services, and professional development, we identified and refined a set of 44 competencies distributed across six domains: knowledge (12 competencies), screening (6 competencies), eligibility (3 competencies), assessment (4 competencies), intervention (10 competencies), and community reentry (9 competencies).

The basal plane of graphene can function as a selective barrier that is permeable to protons but impermeable to all ions and gases, stimulating its use in applications such as membranes, catalysis and isotope separation. Protons can chemically adsorb on graphene and hydrogenate it, inducing a conductor-insulator transition that has been explored intensively in graphene electronic devices. However, both processes face energy barriers and various strategies have been proposed to accelerate proton transport, for example by introducing vacancies, incorporating catalytic metals or chemically functionalizing the lattice.

In their recent Viewpoint article, Beidas et al. (2023) argue that researchers should test psychosocial interventions in the contexts in which they are meant to be delivered and that they can accelerate the deployment of these interventions by advancing directly from pilot trials to effectiveness and implementation studies without conducting efficacy trials. In this commentary, we argue that this is a well-intended but problematic approach and that there is a more productive strategy for translational behavioral intervention research.
