Document Summary

Tasks measuring executive functions in children: a not b task: infants, dccs task: pre-switch = colour , post-switch = shape, simon task: spatial location matching task incompatible stimulus = poorer performance. = repeated successes of finding the toy at a will cause them to go to a even though they see it being hidden at b. Reaching, remembering spatial locations, planning, spatial memory and also executive function as they have to fight a conflicting desire to go to a (as they were rewarded with a before) = performance breakdown in the post-switch trials (when they have to ignore colour and focus only on shape or vis versa) even though being able to answer basic shape or colour questions. Rt on incompatible trials = less accuracy and increased rt. Reaction time: inc rt com rt = int effect, errors: inc errors com errors. Features of stimuli that are interfering (irrelevant stimuli)
