Psychological research on social influence illuminates many mechanisms through which role differentiation and collaborative interdependence may affect cultural evolution. We focus here on psychological processes that produce specific patterns of asymmetric influence, which in turn can have predictable consequences for the emergence and transmission of group-level traits.

Article Synopsis
- Autism presents unique neurodevelopmental differences that make it challenging to understand brain anatomy at a group level.
- The study analyzed neuroanatomical variations in social communication, repetitive behaviors, and sensory processing among a diverse group of autistic and non-autistic participants.
- Results indicated that specific brain features are linked to autism-related behaviors and are connected to genes involved in brain development and synaptic function, highlighting the biological basis of individual differences within neurodiversity.

Article Synopsis
- The study examines a model of populations organized in groups, where birth and death occur at the individual level, and groups can split or go extinct based on their performance in inter-group games.
- Individual strategies evolve through participation in games that affect both personal birth rates and the group’s chances of survival, focusing on dynamics like evolutionary diversification.
- The results show that varying the strength of selection pressure affects adaptability: weaker pressures allow for more flexible group adaptations, while stronger pressures promote individual improvements but hinder group-level evolution.

Background: Autism spectrum disorder (ASD), a neurodevelopmental disorder defined by social communication deficits plus repetitive behaviors and restricted interests, currently affects 1/36 children in the general population. Recent advances in functional brain imaging show promise to provide useful biomarkers of ASD diagnostic likelihood, behavioral trait severity, and even response to therapeutic intervention. However, current gold-standard neuroimaging methods (e.

The brain's sensory lateralization involves the processing of information from the sensory organs primarily in one hemisphere. This can improve brain efficiency by reducing interference and duplication of neural circuits. For species that rely on successful interaction among family partners, such as geese, lateralization can be advantageous.

Heat stress in broilers is a pressing issue in the changing climate. Data on broiler behavior might be useful for early detection of heat stress and subsequent intervention, and may provide potential indicators for heat tolerance that can be used in broiler breeding programs. Here, we used bird location data collected in a previous study during which broilers were inadvertently exposed to high ambient temperatures due to a local heat wave.
