A new review paper proposes that the goal of memory is not to transmit the most accurate information over time, but to guide and optimize intelligent decision making by only holding on to valuable information.
Researchers can look into your eyes to determine whether you're getting your lutein, a pigment found in green leafy vegetables that is known to accumulate in the brain. Two new studies find that children with higher lutein levels in the eye tend to do better than others on tests of cognition and academic achievement, even after accounting for other factors known to influence academic performance such as IQ, gender, body composition and physical fitness.
Many interventions and programs designed to improve low-income children's lives focus on providing high-quality early-childhood education. Preschool classrooms that are emotionally supportive, well-organized, and cognitively stimulating can help boost children's learning and development. Yet for the most part, focusing on the quality of early-childhood education has emphasized teachers, often missing the central role that children play in their own development.
The lateral occipito-temporal cortex (LOTC) is known to be involved in the perception of body parts. Herein, in patients with dementia, the glucose metabolism level in the LOTC was found to be significantly correlated with performance in a task involving mental rotation of the hand. Next, transcranial direct current stimulation (tDCS) of the LOTC in healthy subjects was found to improve the same mental manipulation. This study suggests applicability of tDCS to rehabilitation, for example.
According to a new study by University of Pennsylvania researchers, contrary to the classic notion of 'groupthink,' a group of people with equal influence in a network can arrive at a better prediction than a group with a single influential leader. The findings have implications for decision making in diverse settings, from hospitals to political polling and even climate change forecasting.
Researchers from USC's Institute for Creative Technologies study how reacting with a smile affects game outcomes, hoping one day to empower virtual humans with this knowledge.
Scientists have found a way to improve creativity through brain stimulation, according to researchers at Queen Mary University of London (QMUL) and Goldsmiths University of London.
Second-grade students who read aloud to dogs in an afterschool program demonstrated improved attitudes about reading, according to researchers at Tufts Institute for Human-Animal Interaction at Tufts University.
The question about why more intelligent people tend to be atheistic dates back to the times of Romans and Ancient Greeks. The link between intelligence and religion can be explained if religion is considered an instinct, and intelligence the ability to rise above one's instincts. This is the suggestion by Edward Dutton of the Ulster Institute for Social Research in the UK, and Dimitri Van der Linden of the Rotterdam University in the Netherlands, in an article in Springer's journal Evolutionary Psychological Science.
The ability to engage in joint actions is a critical step toward becoming a cooperative human being. In particular, forming a commitment with a partner to achieve a goal that one cannot achieve alone is important for functioning in society. Previous research has shown that children begin collaborating with others between ages 2 and 3 years. However, it's less clear whether they understand the concept of joint commitments with binding obligations.
