Arthur Jensen model of intelligence consists of abilities operating at two levels. They are:

Spatial and perceptual speed Associative learning and cognitive component 'G' factor and 'S' factor Visual and semantic

Associative learning and cognitive component

Jensen accepts Spearman's idea of a general factor in human intelligence, and his own theory divides intelligence into two distinct sets of abilities: Level I abilities account for memory functions and simple associative learning, and Level II abilities comprise abstract reasoning and conceptual thought.
