This dispa...
A study led by Brigham Young University professor Katie Liljenquist found that clean-smelling environments, such as those with citrus-scented Windex, can improve ethical behavior. Participants in clean-scented rooms were more likely to return a higher share of money in a trust game and show greater interest in volunteering.
A study of 8-year-old children whose mothers ate large amounts of liquorice when pregnant found they performed worse in cognitive tests and had poor attention spans. The researchers linked this to the glycyrrhizin in liquorice, which may impair the placenta and allow stress hormones to cross to the baby.

A new UCLA study examines parents' concerns about development, learning and behavior for young children of Mexican origin, identifying a significant association with family documentation status. The research highlights the need for timely access to primary care and reassurance from pediatric providers to address parental worries.
A new study found that a specific gene, DRD4, is linked to children's temperament and brain activity, with those having the long version of the gene exhibiting more soothable behavior. However, when this gene was combined with increased right frontal cortex activity, it led to attention problems in children.
The reports emphasize the need for a systems approach that considers both technical and sociological/psychological factors in crowd management. This includes training and familiarization with new systems, as well as involving front-line personnel in decision-making. The findings also highlight gaps in knowledge and areas where further ...
A recent review suggests that when caregivers believe their ADHD patients are receiving medication, they tend to view those children more favorably and treat them more positively. This placebo effect may influence how parents and teachers evaluate and behave toward children with ADHD.
A study published in Current Biology confirms that our brains temporarily represent used tools as part of our body schema. This phenomenon affects how we move and perform tasks, with participants exhibiting altered arm movements and perception after tool use.
Parents' attempts to soothe anxiety and assist with OCD behaviors can exacerbate the condition in children, according to a new study published in the Journal of Consulting and Clinical Psychology. Researchers found that accommodations like excessive bathing or checking rituals worsen symptoms, while therapy helps improve outcomes.
