Languages less arbitrary than long assumed

A recent study by Mark Dingemanse and colleagues reveals that language is less arbitrary than previously thought. The researchers found that iconicity, where word forms suggest meaning, and systematicity, a statistical relationship between sounds and grammatical usage, complement arbitrariness in vocabulary structure.

Uniquely human brain region enables punishment decisions

A recent study revealed that the dorsolateral prefrontal cortex (DLPFC) integrates information about a suspect's blameworthiness and harm to others, enabling humans to decide on appropriate punishment levels. The DLPFC is specialized for integrating multiple streams of information to select responses.

Is neuroticism fueled by overthinking?

A new theory proposes that neuroticism is driven by high activity in the brain's self-generated thought centers, which can lead to both creative breakthroughs and negative emotions. The study suggests that overthinking may be a key factor in experiencing intense negative emotions even when there is no apparent threat.

Study links physical activity to greater mental flexibility in older adults

A recent study found that older adults who engage in moderate to vigorous physical activity have more variable brain activity at rest, which is associated with better cognitive performance. The research also revealed that physically fit individuals tend to have larger brain volumes and more intact white matter than their less-fit peers.

How language gives your brain a break

A recent study by MIT researchers found that most languages tend to minimize dependency length (DLM) in practice, preferring words related to each other to be close together. This tendency is associated with simpler language use and reduced cognitive load for speakers, listeners, and readers.

Trying to quit smoking? First strengthen self-control

Researchers found that mindfulness meditation can decrease unconscious influences motivating smokers to smoke, reducing craving rates by 60% in a 2-week study. Integrative body-mind training also decreases stress hormone cortisol levels and increases immune reactivity.

People walk slower, swerve when texting while distracted

A study found that adults who text while being cognitively distracted exhibit a more cautious gait, including increased obstacle clearance and decreased ability to walk in a straight line. The researchers suggest this adaptation may help prevent accidents when faced with cognitive challenges.

Crowdsourcing brain data

A crowdsourcing experiment with over 500 adults yielded new evidence that neurofeedback learning can affect the brain almost immediately. The study demonstrated the scientific viability of collective neurofeedback as a potential new avenue in neuroscience research.

Kessler Foundation TBI study shows brain activity changes after cognitive rehabilitation

A new study published in Journal of Head Trauma Rehabilitation found that traumatic brain injury (TBI) patients who underwent cognitive rehabilitation showed significant changes in cerebral activation. The modified Story Memory Technique (mSMT), a 10-session memory retraining protocol, demonstrated consistent results with prior researc...

How to approach your boss about a treadmill desk

New research from Brigham Young University suggests treadmill desks can increase physical activity in the workplace without significantly impacting cognitive performance. The study found that walkers showed slight decreases in processing speed and attention, but retained their learning and performed well on non-cognitive tasks.

Assumptions of equality lead to poorer group decisions

New research from University College London suggests that people with differing competence give each other's views equal weight, preventing optimal group decisions. This 'equality bias' affects decision-making processes in various contexts, including everyday situations and high-level policy decisions.
