Three experiments are reported which investigated subjects' ability to make the kind of inference required in deriving a concept from positive or mixed positive and negative instances. Ability to make such inferences in a simple letter-group situation (and without the application of time pressure) was found to correlate highly with non-verbal intelligence. Three possible types of error are distinguished and it is shown that liability to one type increased with age even though the different age-groups were matched on non-verbal intelligence. An interpretation is suggested for this age difference.
