Psychological Research of Memory:

Long history of memory research- since the l__ 1__s

Key findings: Memory is constructive meaning that it is c__ or c__ rather than simply r__. (and reconstructive: memories that a__ or o__ details that were not part of an o__ event..) process.

neutral, improved, angry

38
Q

“The m__ race is not as good at identifying m__ as it is its o__ race. This is h__-w__ in some way that we don’t completely understand. But the phenomenon should be presented to the j__,” said Barry Scheck, co-founder of The Innocence Project.

P__, however, do not want j__ to raise the issue with j__.

“This is not an appropriate area for judges to go into,” said Josh Marquis, district attorney in Astoria, Ore., and a member of the executive committee of the National District Attorneys Association. “Yes, eyewitness ID across races has its issues. But is there a rampant problem to the degree that we need to get judges to start telling juries this is the law? No.”

A

majority, minorities, own, hard-wired, jury

prosecutors, judges, juries

39

only, sexual

same

Q

What Can Be Done? Begin with Understanding the Difference Between System vs Estimator Variables:
