America we value speed. So if you are able to do the tests  quickly, then you are more valued in US culture]

-In Japanese culture – different cultural perceptions to time -how a person comes into the testing situation:  We also discuss several other topics like What is the relationship between covariance and the correlation coefficient?

people in Hawaii do things more when they want, when it  comes around. In America we want everything NOW –  

instant gratification.

- Why

o Assessments can be used for high-stakes purposes: PSAT  TAKING PSAT makes you eligible for the consideration of a scholarship o Eligibility to qualify for a national merit scholarship – tests are TIED TO  MONEY

 Determine who needs what services.

 Could mean loss of personal and individual freedoms in the case of involuntary psychiatric hospitalization  

[incarceration].

 Award benefits in the form of access to programs, funding,  admission etc.  

 Issues regarding reliability and validity

- Example of poor validity [one with which you are all quite familiar]

o Student 1 earns 90.6% and 90.2% in two courses [assume both 3 hour courses]

o Student 2 earns 99.8% and 89% in same two courses.  

o Student 1 earns A- and A- [(3.7x3)+(3.7x3)]/6 = 3.7

o Student 2 earns A and B+ [(4x3)+(3.3x3)]/6 = 3.65

 This despite the fact that student 1’s cumulative real  

average is 90.4% whereas student 2’s cummulative real  

average is 94.4%

 When ratio data is placed into bins [letter grades] and then retransformed back to continuous data, INFORMATION IS  

LOST.  

Controversial issues in psychological assessment

- Clinical vs. statistical prediction

o If there were a move, it would have been called Moneytesting o Meehl began claims that statistical interpretation is better than  clinical interpretation

 Where appropriate statistical information exists, clinical  interpretation cannot improve on it

 Critics argue neither process [statistical or clinical] is very  accurate [30% vs. 40%]
