Pedigree-based analyses found that genetic differences account for 50–80% of the variation of observable (phenotypic) traits. Personality traits account for 34–48% of the variance being explained by genetic differences. Molecular genetic studies have also found that intelligence and personality variables … Continue reading
The research strategy adopted in this article is to connect two different discourses and the ideas, methods, and outputs they contain—these being cognitive neuroscience and organization theory. The main contribution of the article is to present an agenda for the … Continue reading
In the brains of Alzheimer’s patients, many of the genes required to form new memories are shut down by a genetic blockade, contributing to the cognitive decline seen in those patients. MIT researchers have now shown that they can reverse … Continue reading
Researchers warn pregnant women and their children to avoid drinking too many sodas, as excessive amounts of sugar in these drinks can negatively impact memory and learning. However, consuming fruits appears to be beneficial for cognitive development, the study reports. … Continue reading
Humans continue to produce new neurons in a part of their brain involved in learning, memory and emotion throughout adulthood, scientists have revealed, countering previous theories that production stopped after adolescence. The findings could help in developing treatments for neurological … Continue reading
A healthy brain is critical to a person’s cognitive abilities, but measuring brain health can be a complicated endeavor. A new study by University of Illinois researchers reports that healthy brain metabolism corresponds with fluid intelligence – a measure of … Continue reading
It happens innocently enough: One minute you’re working on a report and the next minute you’re thinking about how you need to do laundry. Mind wandering is frequent and common. And while it can be counterproductive, research suggests that mind … Continue reading
Recent research provides a whole new understanding of the brain’s amygdala—and suggests that happy people take the bad with the good. You drop a glass while making breakfast. You get stuck in traffic on your way to work. Your boss … Continue reading
Even the simplest networks of neurons in the brain are composed of millions of connections, and examining these vast networks is critical to understanding how the brain works. An international team of researchers, led by R. Clay Reid, Wei Chung … Continue reading
A theory that links memory encoding to expectations of future relevance may better explain how human memory works, according to a team of Penn State psychologists. Modern psychology posits two major theories to explain the mechanisms of how memories are … Continue reading
