Document Summary
Children are able to mentally manipulate ideas about material (concrete) things such as volumes of liquid, dimensions of objects, and arithmetic problems (developmental phenomena conservation and mathematical transformations: formal operations period attained sometimes after age 11. After a brief (15-second) delay, two objects were presented: the first object and a novel object. The participants then had to displace the novel object to obtain the food reward. Nonmatching to sample is thought to measure object recognition, which is a function of the temporal lobes. The task was made more difficult by sequentially giving participants 20 different object pairs. Each day, they were presented with one trial per pair. Just because two things correlate doesn"t mean they cause each other: correlational studies, especially in developmental area have proved a powerful source of insight into fundamental principles of brain and behaviour. Column formation depends on the patterns of coinciding electrical activity on the incoming axons.
