The role of the hippocampus in declarative memory consolidation is a matter of intense debate. We investigated the neural substrates of memory retrieval for recent and remote information using functional magnetic resonance imaging (fMRI). 18 young, healthy participants learned a series of pictures. Then, during two fMRI recognition sessions, 3 days and 3 months later, they had to determine whet...

Number 9 Most of us have a special respect for people with super-memories. Ancient Chinese schoIars were often ranked and esteemed according to the number of idiographs they memorized. Talmudic scholars were respected for memorizing extensive passages of religious works. I have known people who seem to have a " photographic " memory, although scientists believe that no such thing exists. 1 When...

Description of birthmarks having the pattern of strands of a rope in a second known case includes some verification of the correspondence between the birthmarks and injuries from ropes on an identified decreased person.

BACKGROUND The memory deficit hypothesis has been used to explain the maintenance of repetitive behavior in individuals with obsessive-compulsive disorder, yet the majority of studies focusing on verbal memory show mixed results. These studies primarily evaluated memory accuracy via the inclusion or omission of previously encountered material, as opposed to false recognition (i.e., the inclusio...

Compared to young, older adults are more likely to forget events that occurred in the past as well as remember events that never happened. Previous studies examining false memories and aging have shown that these memories are more likely to occur when new items share perceptual or semantic similarities with those presented during encoding. It is theorized that decreased item-specific encoding a...

We study the problem faced by a supplier deciding how to dynamically allocate limited capacity among a portfolio of customers who remember the fill rates provided to them in the past. A customer’s order quantity is positively correlated with past fill rates. Customers differ from one another in their contribution margins, in their sensitivity to the past, and in their demand volatility. We seek...
