The Development of Controlled Attention

The ability to maintain items of information within working memory is depending on the ability to allocate attention to items within WM. Individual differences in WM capacity may bedependent on the amount of information that can be held and maintained in the focus of attention. A basic question in cognitive development is whether individuals increase the capacity of the focus of attention or the efficiency with which they can process information. We examined the differences in typically developing children versus adults in the capacity and efficiency of attention control. In our study, children and young adults completed a dichotic attention switching task and their accuracy and response time was measured. Children’s accuracy on the attention switch tasks was not significantly different from adults’ accuracy. Children had significantly slower response time compared to the young adult group. The results of our study suggest that developmental changes in capacity of WM were not present for the task, but changes in processing speed and efficiency were critical cognitive mechanisms that influenced changes in inhibition from adolescence to adulthood. Our next step is to analyze neural processing data in order to assess developmental differences in the amount of cognitive energy required for both groups to perform these tasks

Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA)

With their extensive coverage, marine low clouds greatly impact global climate. Presently, marine low clouds are poorly represented in global climate models, and the response of marine low clouds to changes in atmospheric greenhouse gases and aerosols remains the major source of uncertainty in climate simulations. The Eastern North Atlantic (ENA) is a region of persistent but diverse subtropical marine boundary layer clouds, whose albedo and precipitation are highly susceptible to perturbations in aerosol properties. In addition, the ENA is periodically impacted by continental aerosols, making it an excellent location to study the cloud condensation nuclei (CCN) budget in a remote marine region periodically perturbed by anthropogenic emissions, and to investigate the impacts of long-range transport of aerosols on remote marine clouds. The Aerosol and Cloud Experiments in Eastern North Atlantic (ACE-ENA) campaign was motivated by the need of comprehensive in-situ measurements for improving the understanding of marine boundary layer CCN budget, cloud and drizzle microphysics, and the impact of aerosol on marine low cloud and precipitation. The airborne deployments took place from June 21 to July 20, 2017 and January 15 to February 18, 2018 in the Azores. The flights were designed to maximize the synergy between in-situ airborne measurements and ongoing long-term observations at a ground site. Here we present measurements, observation strategy, meteorological conditions during the campaign, and preliminary findings. Lastly, we discuss future analyses and modeling studies that improve the understanding and representation of marine boundary layer aerosols, clouds, precipitation, and the interactions among them
