How Memory Works

Study shows the tools used to assess whether mental ability tests are biased couldn’t find bias when it was deliberately inserted, casting the fairness of common tests into doubt.

Manipulation of nearly 16 million individual samples of scores and more than 8 trillion individual scores on commonly used tests, including civil service and other pre-employment exams and university entrance exams, has revealed that the tools used to check tests of "general mental ability" for

The existence of specialized neurons involved in spatial memory has now been found in humans, and appear to also help with object location and autobiographical memory.

Rodent studies have demonstrated the existence of specialized neurons involved in spatial memory.

Providing support for a modular concept of the brain, a twin study has found that face recognition is heritable, and that it is inherited separately from IQ.

No surprise to me (I’m hopeless at faces), but a twin study has found that face recognition is heritable, and that it is inherited separately from IQ.

Findings from a survey of adolescents provides support for a theory that more intelligent people are more likely to adopt evolutionarily novel preferences and values, and that these values include liberalism, atheism, and, in men, monogamy.

A new theory suggests that more intelligent people are more likely than less intelligent people to adopt evolutionarily novel preferences and values, and that these values include liberalism (caring about numerous genetically unrelated strangers they never meet or interact with), atheism, and, i

An imaging study reveals that different brain regions are involved in learning nouns and verbs.

A monkey study reveals that, although some neurons are specialized to recognize specific concepts, most are more generalized and these are usually better at categorizing objects.

Previous research has found that individual neurons can become tuned to specific concepts or categories. We can have "cat" neurons, and "car" neurons, and even an “Angelina Jolie” neuron.

Several reports have come out in recent years on how recent events replay in the hippocampus, a process thought to be crucial for creating long-term memories. Now a rat study suggests that these replays are not merely echoes of past events, but may include possible events that never happened.

Perhaps we should start thinking of language less as some specialized process and more as a particular approach to thought. A study involving native signers of American Sign Language adds to the increasing body of evidence that we process words in the same way as we do the concepts represented by the words; speaking (or reading) is, neutrally speaking, the same as doing.

Perhaps we should start thinking of language less as some specialized process and more as one approach to thought.

Visual working memory, which can only hold three of four objects at a time, is thought to be based on synchronized brain activity across a network of brain regions. Now a new study has allowed us to get a better picture of how exactly that works.

It’s now well established that sleep plays an important role in memory and learning. Now a new study suggests that dreams also play a part in consolidating memories — perhaps reflecting the brain's attempt to find useful associations.
