The Neurocognitive Developmental Laboratory (NDL) is a research group, in the discipline of Psychology within the School of Population Health, at Curtin University. Our primary research goal is to examine the sources of differences in cognitive ability. That is, we wish to understand the mechanisms that account for the differences in ability between people of the same age (individual differences) and the differences in ability between people of different ages (cognitive development). For example, we are interested in examining what underlies variability on tests of academic achievement, standardised measures of intelligence, problem solving, reasoning, and language development. We are also interested in examining the basis of cognitive variability observed in developmental disorders (such as, specific language impairments, autism and Down's syndrome), as well as what may account for particular patterns of breakdown in adult cognition (e.g., following brain trauma, or disease).....
