experienced at 65 may be much different from those experienced at younger ages。
。 Environmental cues for memory also decrease as people grow older。 Houses and other structures they
remember have been replaced； family and friends have died or moved away； streets and roads have
been replaced by expressways； and fields and forests have been replaced by buildings。
。 Memory failures in older people may have a physiological cause。 Neurons involved in a memory or in
the associations that would lead to a memory may have degenerated； or the supply of an important
neurotransmitter like acetylcholine may have decreased。
。 Depression in the elderly may be a cause of memory loss。 As a function of such factors as living alone；
being widowed； living far from one’s children； watching one’s friends and acquaintances bee ill and
die； and their own deteriorating physical health are all more than adequate reasons for depression。
Depression brings limited attention。 If the attention span of an elderly individual is impaired as a
conitant of depression； memory impairment may follow。
BIOGRAPHICAL PROFILES
Hermann Ebbinghaus （1850—1909）
Born in Barmen； Germany； Ebbinghaus was instrumental in the development of the new
science of experimental psychology at the turn of the century。 A professor at both Breslau and
Halle； he was the first experimentalist to conduct vigorous laboratory investigations of human
learning and memory。 Using himself as a participant； Ebbinghaus memorized long lists of
nonsense syllables that he believed had no prior meaning or associative value。 His research
resulted in several discoveries； including the finding that as the quantity of material to be
learned increases； the amount of time needed to learn it increases disproportionately； known as
Ebbinghaus’ Law； and the serial position curve。

CHAPTER 8： MEMORY
Endel Tulving （b。 1927）
Born in Estonia； Endel Tulving was educated at the University of Heidelberg and the
University of Toronto before obtaining his Ph。D。 at Harvard in 1951。 He taught at the
University of Toronto for most of his professional career。 His major contributions include both
experimental and theoretical work on human memory。 In particular； Tulving has introduced
many of the concepts that are today considered indispensable to understanding human
cognition and memory； including subjective organization； retrieval cues； and the distinction
between episodic and semantic memory。
Elizabeth F。 Loftus （b。 1944）
Born in Los Angeles； Loftus earned her B。A。 in psychology at UCLA in 1966 and her Ph。D。 at
Stanford in 1970。 She has been a professor of psychology at the University of Washington since
1975。 Professor Loftus’ area of specialty is human memory。 Her expertise is in the area of
eyewitness testimony； and she is often referred to as “the expert who puts memory on trial。”
Loftus has made a career of exploring the frailties and flaws of human memory； particularly
with respect to the validity of memories encoded under duress； such as when witnessing a
crime or being a victim of a crime。 She is sought after as the expert witness who can explain to
juries the fallibility of human memory； and help them to understand that what the eyewitness
says he or she saw may； in reality； be due to post…event information that has been encoded and
incorporated into the original memory。

DISCOVERING PSYCHOLOGY
PROGRAM 9： REMEMBERING AND FORGETTING
Overview

sounds； and smells are translated into codes； represented in the memory； and retrieved when
needed。

from memory； memory engrams； and organic amnesia。
Demonstrations
Gordon Bower demonstrates the peg…word mnemonic； a memory enhancing technique。
