I'm conducting research on the correlation between working memory and intelligence in college aged students. Can anyone help me find an intelligence test to use, and if so, tell me where to get a usable copy of it from? Thanks in advance!
one of the measures I would suggest using is the Wechsler Adult Intelligence Scale (WAIS-IV). The scale has been standardized on a sample ranging from 16 to 90 yrs, so it should work in your case.
You can also look at single subtests if you don't want to spend >60 minutes administering the whole scale. The scale should also provide a WM index.
Otherwise you can look at Raven's Matrices (there is a similar test within the WAIS), it should provide you with an index of people's abstract reasoning abilities/non-verbal fluid intelligence.
Regarding the usable copy, since they are not free tools, you should check if your department/library had already bought them in the past or is willing to acquire them.
Functional intelligence is significantly different than normed intelligence scores. Thus you may wish to question using normed tests like the WAIS if such a measure will be used predictively. WAIS does not reliably predict individual behaviour. However, if you add in and confirm functional measures such as 'what is your class attendance record?' 'How often are you late for appointments?' 'Have you ever been fired from a job due to tardiness?' etc, etc, etc,
Such functional measures are not always valid, but they will be useful in a college population - useful indicators of behavioural initiative and endurance.
