In order to investigate the effect of cognitive stimulation on personality later in life, the individuals were divided into two treatment groups, ‘stimulated’ (n=84) and unstimulated, ‘control’ (n=89). As part of other studies, the simulated individuals were involved in a battery of learning tasks, including associative, reversal, spatial, generalisation and a selective attention tasks. The unstimulated control individuals were handled and given mealworms in the test arenas (which included all the test cues and bowls), but did not have to perform to attain mealworms. All individuals were as adults scored in personality assays including a novel arena and a novel object test.
