Why our Memory is Unreliable
Memory is not a filing cabinet nor a videotape but fragmentary, malleable, and untrustworthy. Hence the introduction of radical new eyewitness testimony rules.
What's the Latest Development?
The New Jersey Supreme Court this week released radical new rules on the use and misuse of eyewitness testimony. The ruling has profound legal implications, making it much easier for defendants to dispute eyewitness evidence in court. The ruling also reflects decades of scientific research on human memory and the core idea—which can be traced back to research by Elizabeth Loftus—that human memory is untrustworthy.
What's the Big Idea?
Universities claim to prepare students for the world. How many actually do it?
- Many university mission statements do not live up to their promise, writes Ben Nelson, founder of Minerva, a university designed to develop intellect over content memorization.
- The core competencies that students need for success—critical thinking, communication, problem solving, and cross-cultural understanding, for example—should be intentionally taught, not left to chance.
- These competencies can be summed up with one word: wisdom. True wisdom is the ability to apply one's knowledge appropriately when faced with novel situations.
This is what the world will look like, 250 million years from now
To us humans, the shape and location of oceans and continents seems fixed. But that's only because our lives are so short.
A new study may help us better understand how children build social cognition through caregiver interaction.
Researchers at UT Southwestern noted a 47 percent increase in blood flow to regions associated with memory.
- Researchers at UT Southwestern observed a stark improvement in memory after cardiovascular exercise.
- The year-long study included 30 seniors who all had some form of memory impairment.
- The group of seniors that only stretched for a year did not fair as well in memory tests.
