Do Child Gender Stereotypes Mediate Associations Between Human Fathers' Testosterone Levels and Paternal Involvement? Two Studies.

This preregistered study investigated whether human paternal testosterone levels predicted fathers' time spent with their child and their involvement in childcare and household tasks. Additionally, we examined whether associations were mediated by fathers' attitudes toward child gender stereotypes. Associations were tested in an exploratory sample (n = 70, M = 6.

Hypermobile Ehlers-Danlos Syndrome: Cerebrovascular, Autonomic and Neuropathic Features.

Background: Hypermobile Ehlers-Danlos syndrome (hEDS) affects multiple systems, but comprehensive evaluations of a larger sample of hEDS patients are lacking. The objective of this study was to describe cerebrovascular, autonomic, and neuropathic features of hEDS.

Methods: This retrospective case-control study was conducted at Brigham and Women's Faulkner Hospital between 2016-2023.

Conjoint behavioral consultation and students of Latine origin: Effects on social and behavioral outcomes at school and home.

Latine students represent the second largest racial/ethnic group of enrolled students in the United States. Despite assets that can position them to experience success in school, Latine youth often experience persistent disparities in educational outcomes. Conjoint behavioral consultation (CBC) is a family-school partnership intervention efficacious for supporting students' social-behavioral skill development, yet its efficacy with Latine students has not been documented.

The utility of explainable AI for MRI analysis: Relating model predictions to neuroimaging features of the aging brain.

Deep learning models highly accurately predict brain age from MRI but their explanatory capacity is limited. Explainable artificial intelligence (XAI) methods can identify relevant voxels contributing to model estimates, yet they do not reveal which biological features these voxels represent. In this study, we closed this gap by relating voxel-based contributions to brain-age estimates, extracted with XAI, to human-interpretable structural features of the aging brain.

Neural responses to visual food cues according to weight and hunger state: A systematic review and meta-analysis.

Background: Food cue reactivity shapes eating behavior and likely relates to weight and hunger states. Functional Magnetic Resonance Imaging (fMRI) studies, however, have yielded mixed results on the underlying neural correlates. We, therefore, conducted a systematic review and meta-analysis to investigate the effect of weight and hunger on neural responses to food cues.
