How Memory can be manipulated, with Elizabeth Loftus, PhD | Speaking of Psychology

Our memories may not be as reliable as we think. Once we experience an event, most of us likely assume that those memories stays intact forever. But there is the potential for memories to be altered or for completely false memories to be planted, according to Elizabeth Loftus, PhD. Loftus, a distinguished professor at the University of California, Irvine, is an expert on human memory and she discusses how our recollections of events and experiences may be subject to manipulation.

The American Psychological Association is the leading scientific and professional organization representing psychology in the United States, with more than 157,000 researchers, educators, clinicians, consultants, and students as its members.

The US test fired its most powerful laser ever

Accomplishing this and other experimental feats does require some safeguards. ZEUS includes optical devices known as diffraction gratings that stretch out the initial infrared pulse over time. This ensures the initial power doesn’t get so intense that it begins tearing apart the air around it.

Another goal is to ultimately create beams of electrons with energies similar to those found in particle accelerators hundreds of feet longer than ZEUS at a fraction of both its size and operating costs. At only $16 million to construct, the University of Michigan previously described the machine as a “bargain.”

Years of construction, calibration, and expertise is showcased in an astoundingly short amount of time. ZEUS’ 2 petawatt firing lasted just 25 quintillionths of a second. But future experiments will make the most of these moments.
