A rapid face recognition method has been developed that can accurately identify individuals despite disguises and varying lighting conditions. The new algorithm reduces computer power requirements without compromising accuracy, making it suitable for real-world applications such as border crossings and automated banking.
A new study by Timothy Judge and colleagues found that physical attractiveness has a significant impact on income, with good-looking individuals making more money, being better educated, and more confident. Intelligence still plays a stronger role in determining income, but having both traits can lead to higher pay.
Researchers have identified two key brain regions responsible for forming first impressions, including the amygdala and posterior cingulate cortex. These regions process emotional and value-based information to form a quick and lasting impression of others.
A new study published in PLOS ONE suggests that the first egalitarian societies may have appeared tens of thousands of years ago, driven by the social brain hypothesis. The research uses a complex mathematical model and large-scale numerical simulations to explore how alliances can emerge in groups, leading to a phase transition toward...
A study found that participants with greater activation in the anterior prefrontal cortex, a key brain structure for short-term memory, scored higher on intelligence tests and exhibited better self-control. This neural link suggests that improving brain function in this area may lead to increased self-control.
A study published in The FASEB Journal found that gerbils given specific compounds increased brain synapses and improved cognitive tasks. Researchers discovered more brain synapse activity consistent with higher intelligence after dissecting mouse brains.
The Great Ape Trust of Iowa has signed a Memorandum of Understanding with Universitas Nasional in Jakarta, Indonesia, to enhance academic cooperation and conserve Sumatran orangutans. The partnership will provide opportunities for students from around the world to study rapidly disappearing orangutans in the wild.
A study of Vietnam war veterans with brain injuries found that those with higher intelligence and education levels before injury experienced a slower decline in cognitive functioning. The researchers also identified genetic markers associated with cognitive recovery or decline after head injury.
A distinct neurobiology of human intelligence has been identified through a review of brain imaging studies. The Parieto-Frontal Integration Theory suggests that the frontal and parietal lobes are key areas involved in intelligent information processing, with some overlap with attention, memory, and language functions.
A study found that students who believe their intelligence can be developed outperform those who think it's fixed, especially in math grades. Students with a growth mindset are more motivated, work harder, and bounce back from setbacks.
A region of the human brain believed to be critical to intellectual abilities functions much like a digital computer, according to CU-Boulder Professor Randall O'Reilly. The prefrontal cortex and basal ganglia operate by turning electrical signals into binary states and flexibly manipulating them, similar to digital computers.
A new study found that open-mindedness predicts higher intelligence in young adults, while disagreeableness is linked to better vocabulary and knowledge retention in older age. Conscientiousness also plays a role in strong short-term memory and visual processing in older adults.
Researchers found a specific pattern of DNA sequence variations in the dysbindin gene associated with impaired cognition and intelligence. The study suggests dysbindin influences variation in human cognitive ability, but only explains a small proportion, about 3 percent.
A study published in Psychology of Women Quarterly found that businesswomen wearing tight skirts were perceived as less competent than their neutrally dressed counterparts. The research suggests women in high status occupations must resist the temptation to emphasize their sex appeal to gain respect from colleagues.
A comprehensive study of 26 international studies shows a strong correlation between brain volume and intelligence, with average intelligence increasing with brain size. The findings have significant implications for job performance and could lead to more accurate employment screening methods.
Researchers find that consumers perceive defaults as indicative of marketers' intentions, leading to biased choices. This phenomenon is known as marketplace metacognition, where consumers try to decipher the marketer's intended choice.
Research suggests that bilingual individuals can maintain their attention and reaction time better than monolingual counterparts as they age. Bilingualism was found to attenuate the age-related decline in cognitive processing efficiency, particularly in tasks requiring inhibitory control.
Researchers at Duke University found that ringtails and mongoose lemurs can learn sequences of pictures and discriminate quantities. The animals show a systematic learning ability and can recognize larger quantities, but their numerical abilities are not as sophisticated as those of monkeys and apes.
Recent baboon studies provide insights into the complexity of monkey social behavior and suggest that natural selection has favored sophisticated social intelligence in primates. This research may inform theories concerned with the evolution of human language and cognition.
A new brain imaging study from Washington University in St. Louis has shed light on the inner workings of human intelligence, revealing that individuals with higher fluid intelligence use specific brain regions to resist distraction and maintain focus. The study found that participants with higher fluid intelligence engaged several key...
The American Psychological Association and FBI report highlights the importance of social science techniques in combating terrorism. Three key strategies emerge: information exchange using data mining and decision tree techniques, relationship-building with key communities, and effective interrogation/interviews.
Researchers found that watching classic horror films improved reasoning and intelligence, while anxious moods hindered performance on difficult tasks. The prefrontal cortex region was jointly influenced by mood state and cognitive task, suggesting a regulatory role in integrating emotional signals with cognition.
Research suggests that breastfeeding duration may impact cognitive development. Children breastfed for less than three months were more likely to score below average on mental skills and total intelligence at ages 13 months and 5 years. The study controlled for factors like mother's age, education, and smoking habit.
Research debunks popular belief on family size and intelligence, suggesting no direct causal link between the two. Instead, factors like parental IQ and genetic heritage may influence children's intelligence.
Researchers found that lower precombat and current intelligence were associated with PTSD symptoms among Vietnam veterans. Lower intelligence may lead to increased feelings of overwhelm and helplessness, increasing the risk for chronic PTSD.
