Intelligence: major theories

Intelligence has been theorised as one general factor, as many separate abilities, and as practical and emotional skill. For example, Spearman would explain correlated test scores by a single g, while Gardner would explain a brilliant musician with weak maths by separate intelligences. This chapter covers Spearman, Thurstone, Jensen, Cattell, Gardner, Sternberg, Goleman, Das, Kar and Parrila.
