| Sumario: | The writer discusses empirical findings on the importance of assessing individual differences in human behavior. He notes that traditional dimensions of human abilities, vocational interests, and personality play important parts in structuring a range of important behaviors and outcomes. He explores the importance of these traditional dimensions, considering the construct of general intelligence; but he also reviews attributes that routinely add incremental validity to cognitive assessments. He then considers recent experimental and methodological advances for better understanding how these dimensions might contribute to other psychological frameworks; and he examines methods for determining their scientific significance within domains where they are not routinely evaluated. Furthermore, he outlines some noteworthy models that emphasize the importance of assessing relatively distinct classes of individual-differences attributes at the same time. He contends that in order to understand fully complex human phenomena such as crime, eminence, and educational-vocational development, a multifaceted approach is likely to be most productive.
