Intelligence

Intelligence

1. Reliable

   • how consistent the measure is
   • test-retest reliability
     • Give test. Wait a white. Give again.

2. Valid

   • measures what is is intended to measure
   • Predictive valifity

3. Overlap

   • Factor analysis
     • common/general factors
       • some depend heavily
       • some depend less
       • General Intelligence (g)
         • alot
           • well in every intellectual endeavor
         • short suppply
           • poorly in a wide range
         • moderate strong correlation among subsets
           • Stronger correlation among category's subset
         • Proposal: mental process are quick but take time
           • Inspection time
           • Smarts are fast in process
             • perform tasks quickly
         • Proposal: WMC
           • Smarts have better control
             • coordinate priorities approprately
             • avoid distraction
             • override impulses
         • Proposal: task model
           • understand goals, rules, requirements
             • "agenda"
           • Parieto-frontal integration theory
             • control of attention
