Cattell–Horn–Carroll Model History
CHC is theory of cognitive abilities is an unification of two similar theories about human cognitive abilities. The first of these two theories is Gf-Gc theory (Raymond Cattell, 1941; Horn 1965), and the second is John Carroll's (1993) Three-Stratum theory.
CHC Model
• CHC theory involved the use of the mathematical technique known as factor analysis
• In comparison to other well-known theories of intelligence and cognitive abilities, CHC theory is the scientifically proven and well structured theory
Raymond Cattell Cattell proposed that there were two overall
abilities people have: Crystallized intelligence and fluid intelligence
Crystallized intelligence reflected abilities that were relatively static (such as learned information)
Fluid intelligence was more related to “On the spot” problem solving
1
-- acquired knowledge and experience-- age
Crystallized intelligence
Fluid intelligence
-- problem-solving, learning and pattern recognition
2John Horn
Added Seven to Sixteen broad abilities
Broad
• Gc – crystallized intelligence
• Gf – fluid intelligence
• Gs – processing speed
• Gt – reacting or decision making speed
• Gsm – short-term or immediate memory
• Glr – long-term memory storage and retrieval
• Grw – reading and writing ability
• Gq – quantitative reasoning
• Gv – visual processing
• Ga – auditory processing
3John Carroll
General ( Stratum III ) : general intelligence factor “g”
Broad ( Stratum II ) : fluid and crystalized intelligence
Narrow ( Stratum I ) : 73 narrow abilities, each related to a specific Stratum II domain.
• Fluid Reasoning:– To solve novel “on the spot” problems – Not relying on previously learned habits
• Memory:– Short Term Memory– Long Term Memory and Retrieval
• General Speed:– Reaction-Decision Speed – Psychomotor Speed
- Fluid Reasoning
- Memory
- General Speed
Domain-Independent General Capacities
• Crystallized:– Includes the breadth and depth of a person's
acquired knowledge
• Comprehension:– Depth and breadth of knowledge and skills that
are valued by one’s culture.
• Domain Specific:– typically acquired via one’s career, hobby – other passionate interest (e.g., religion, sports)
• Reading & Writing:– related to written language
• Quantitative:– related to mathematics

Sensory-Motor Linked Abilities
- Visual Processing:
- ability to make use of visual senses
- Auditory Processing:
- ability to detect and process nonverbal
data in sound
- Olfactory Abilities:
- ability to detect and process meaningful
information in odors
- Tactile Abilities:
- ability to detect and process meaningful
information in haptic (touch)

body motor movements

CHC Tests
• CHC Model tests (aptitude tests, general intelligence assessments) are one of the most powerful predictors of cognitive abilities
• These tests measure verbal, numerical and abstract reasoning and the resulting score reflects the person's ability to acquire, retain, organise and apply information
CHC Tests
People who score well on cognitive ability tests are more likely to:
• Develop a greater knowledge of the task, more quickly
• Make effective decisions• Successfully reason , solve problems • Respond appropriately to new or complex situations
