What is intelligence (1)

In this session, you will be introduced to key theories of intelligence and how they relate to psychometric testing, including an overview of single-factor and multifactor models. Dr Graham Tyler explains the origins of intelligence testing, such as Binet’s early work and the development of IQ, alongside contributions from theorists like Spearman and Thurstone. You’ll also gain an understanding of the ongoing debates around defining intelligence and learn why it’s important for psychometric assessment in the workplace.

After this talk, you will:

• Have a brief overview of major intelligence theories as they relate to psychometric assessment.

• Understand the difference between single-factor and multi-factor models of intelligence.

• Recognise the difficulty in defining intelligence and that even experts do not always agree on its meaning.

• Know about Binet’s role in developing the first modern intelligence test and the concept of mental age.

• Understand how the IQ (intelligence quotient) was originally calculated and its limitations, especially with adults.

• Be aware that IQ is a standard score and can be applied beyond intelligence tests.

• Learn about Spearman’s concept of general intelligence (‘g’ factor) and his use of factor analysis.

• Understand the criticism of single-factor theories and the existence of specific factors.

• Be introduced to Thurstone’s multifactor theory and the idea that intelligence is made up of several abilities.

• Appreciate that the field of intelligence testing is complex and evolving, with ongoing debates about models and definitions.
