Q: What are the PRO's of IQ Testing?
|
- predict short-term school performance
- assess individuals strengths & weaknesses - Predict occupational achievement -Reveal important personality variables -allow us to trace possible changes in an individual/population |

|
Q: What are the reliability statistics of the WISC-IV? Internal consistency? test-retest?
|
Internal - FSIQ-.97

|
Q: Cons of IQ testing?
|
-IQ scores don't measure innate, fixed ability, and their use in classifying minority groups has been questioned
-there has been an overemph on understanding end product of cog functioning & neglect in appreciating underlying cog processes - limited in predicting certain apsects of occu success and non academic skills |
