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.

Researchers found that people attribute meaning to dreams based on their waking beliefs and desires. Pleasant dreams about a person they liked were considered more meaningful than unpleasant ones, while an actual plane crash produced a similar level of anxiety as did a dream of it.
A new study by Rush University Medical Center researchers has discovered a behavioral link between insomnia and tension-type headaches. Eighty-one percent of women with tension-type headaches reported going to sleep as a way to manage their headaches, which was also the most effective self-management strategy for pain.

The study of human fossils from Sima de la Palomas reveals the persistence of Neandertals until around 40,000 years ago. This challenges the idea that they were quickly displaced by modern humans, indicating a more complex picture of contact and coexistence between different human populations.
Purdue researchers found that lab mice can relieve stress by controlling their environment through behaviors such as selecting preferred temperatures and building nests. This suggests that allowing lab animals to express natural behaviors may improve research data reliability.
The Panamanian termite has recorded the fastest mandible strike ever, with footage showing a soldier termite's jaws striking an invader at speeds of up to 70 meters per second. This rapid strike is thought to be due to the termites' need to store energy in their mandibles to generate force.
The study examines the meaning of employee engagement, which involves positive feelings about the job and motivation. The authors conclude that employers must create conditions that respect employees' energy and facilitate engagement through fair treatment, creating a feeling of trust and safety.
Researchers found that rats and humans with disrupted attention share similar patterns of behavior in a feature binding task, suggesting acetylcholine is necessary for this process. The study has important clinical implications, potentially leading to improved therapies for disorders like Alzheimer's disease.
A groundbreaking study reveals that the color red makes men feel more amorous toward women, with no effect on female perceptions. The research confirms what many women have long suspected - that men's preferences are driven by primal instincts.
A study by CU-Boulder Assistant Professor Lawrence E. Williams found that holding a hot cup of coffee or cold compress pads primes subjects to perceive others as warmer or colder, respectively. This association affects pro-social behavior and marketing strategies.
Researchers found a substantial inconsistency between healthful snack choice intentions and actual behavior, with 27% switching to unhealthy snacks when presented. However, individuals who plan to make a healthy choice are more likely to do so than those who plan to make an unhealthy choice.
A new study found that mothers who delivered vaginally are more responsive to their baby's cry due to increased brain activity in regions regulating emotions and motivation. This could lead to better understanding and early detection of postpartum depression and attachment problems.
School-based programs have been shown to be effective in reducing prevalence of childhood overweight and obesity through interventions such as physical activity education and nutritional education. The URMEL-ICE program demonstrates a significant reduction in body fat mass among children after one year of participation.
Researchers at UC Davis developed a control system that allows robots to pick up on cues and predict where leaders are going, enabling them to follow accurately around corners. The system uses behavioral cues such as head turns and incorporates them into decision-making processes.
A new study shows that people can create false memories of their past, which can lead to lasting changes in their behavior. Participants who were told they had become ill after eating egg salad as children avoided the food and gave it lower evaluations than those who did not develop false memories.
Scientists at Johns Hopkins University found that two brain areas handle complex rules: the prefrontal cortex controls rule changes and parietal cortex controls number switches. This discovery may lead to enhanced understanding of mental illnesses with impaired rule-changing abilities.
Researchers at Cold Spring Harbor Laboratory discovered that laboratory rats' brains signal uncertainty when making decisions, reflecting their level of confidence. The study found that rats preferentially abort uncertain trials, indicating that confidence plays a crucial role in guiding behavior.
The University of Houston's Texas Obesity Research Center (TORC) is recruiting 500 participants for a study promoting healthy dietary habits and physical activity in the virtual world of Second Life. Participants will earn rewards and compete to win the International Health Challenge.
A new study from Tel Aviv University finds that people's response to risk is driven by personal experience and simple strategies for coping in nature, rather than logical rationales or statistics. This behavior may not be well-suited for the modern world, where risks are more complex and unpredictable.
Researchers used data mining to identify subtle differences in movement between rats with ALS mutations and controls, predicting the onset of disease two months early. This novel approach may enable testing of therapies to delay or prevent disease.
