Associate Professor Christopher L Asplund received his A.B. in Psychology (Cognitive) from Princeton University (2003) and his Ph.D. in Integrative and Cognitive Neuroscience from Vanderbilt University (2010). He then moved to Singapore, joining Duke-NUS as a research fellow in 2010. He participated in the inaugural year of Yale-NUS development and then joined the faculty in 2013.
Assoc Prof Asplund studies attentional control and its relationship to consciousness. Attentional focus is influenced by multiple factors, including goals, action history, cognitive state, and events in the environment. Although these influences usually lead to successful behaviours, attention may be misallocated or overwhelmed. For example, we may fail to see something right before our eyes or to do two things at once.
Assoc Prof Asplund’s research addresses how such limitations arise, how they might be circumvented, and what they reveal about control and consciousness. To explore these ideas, he and his colleagues conduct behavioural and neuroimaging (fMRI) experiments. These investigations centre on fundamental research in vision but extend to audition and somatosensation, as well as to applied work with training and human-computer interactions.
