Excellent definitions from Kevin S. McGrew in Intelligence 37 (2009) 1–10. You can’t get much more up-to-date than this.
Fluid intelligence (Gf): The use of deliberate and controlled mental operations to solve novel problems that cannot be performed automatically. Mental operations often include drawing inferences, concept formation, classification, generating and testing hypothesis, identifying relations, comprehending implications, problem solving, extrapolating, and transforming information. Inductive and deductive reasoning are generally considered the hallmark indicators of Gf. Gf has been linked to cognitive complexity which can be defined as a greater use of a wide and diverse array of elementary cognitive processes during performance.
Tests include: General sequential (deductive) reasoning, Inductive reasoning, quantitative reasoning, speed of reasoning
—————————
Crystallized intelligence (Gc): The knowledge of the culture that is incorporated by individuals through a process of acculturation. Gc is typically described as a person’s breadth and depth of acquired knowledge of the language, information and concepts of a specific culture, and/or the application of this knowledge. Gc is primarily a store of verbal or language-based declarative (knowing what) and procedural (knowing how) knowledge acquired through the investment of other abilities during formal and informal educational and general life experiences.
Tests include: Language development, Lexical knowledge, Listening ability, General (verbal) information, Information about culture, Communication ability, Oral production and fluency, Grammatical sensitivity, Foreign language proficiency, Foreign language aptitude.

Hi ,
Foe my studies , i developed an assessment tool which in my opinion measures a learners Fluid intelligence , what I did was to combine 24 manipulative questions and 2 sets of 20 questions (perceptual) also visual intyo the test battery , I then integrated the result into a single answer which I color coded. This they do in conjunction with a visual 3 d test and simple color test – to look for simplistic color blind ness, I ten compare these resultus with results I obtain from a service provider once the same learner went for Vienna Dover assessment —- this measures psychomotor etc with a bit of cognitive measurement,
My objective is to identify those workers whom I greater opportunity of injuring themselves on the mine. In the past we only used Vienna Dover , but it is my opinion that this battery which they do by me is just as effective, eventhough it does not measure the same “intelligence” , I really believe that if you have a high preceptual and manipulative ability , which gives you problem solving skills, you will not hurt yourself on the mine.
Thus far…. if a learner scores red in Vienna Dover , they score red in my assessment , green / green, I have tested more than 80 people in the past 3 months
I have also found that more than 80% of workers who injure themselves on site fail my test as well as Vienna Dover
……………………………………..
My question…. Has any studies been done between Vienna Dover / pschomotor and Fluid INTELLIGENCE and what has the findings been.??
Kind Regards

Hi – I think this would be an excellent study. There IS evidence that an area of the brain called the pre-motor cortex (directly involved in perceptual-manipulative motor ability) is involved in fluid intelligence processes. I’ll try to find the reference – I just read the paper recently, but didn’t file it. I think the study you suggest would be a great one – why not do it! Just get the Raven Advanced Progressive Matrices test, and do the correlation study. You could also do an intervention! Train for 20 days on the dual n-back, and see if this improves scores on the motor skills. That would be a remarkable finding.
