This great flexibility relies on three cognitive abilities in concert. Firstly, one must maintain goal-relevant representations in short-term memory (STM). Next, achieving one’s goal depends on the anticipation of upcoming events, and one must act in such a way that the future outcome will be in accordance with the desired outcome. Finally, such anticipation relies on one’s past experiences associated with goal-relevant information for a particular event. Together, one must use past experiences or prior knowledge to prepare for appropriate actions whilst adjusting behaviours towards the goal based on the task. Experience of task is thus of considerably importance in human cognition. However, despite the unquestionable progress of research on human cognition to date, the field has scarcely considered the critical role that task experience in driving unconscious influences on the preparation and maintenance for the relevant events. This grant proposal aims to explore whether and how task experience could enable unconscious influences on the STM representations. I will conduct machine learning based analysis on functional brain imaging data and decode the neural representations for brain oscillations and functional maps/connectivity using noninvasive brain imaging methods including electroencephalography (EEG) (first year), functional magnetic resonance imaging (fMRI) (second year), and magnetoencephalography (MEG) (third year) as well as behavioural measures. Results from this research proposal will build up the empirical foundation and provide the intellectual impetus for in-depth work into this essential but this far neglected aspect of human cognition – the way in which task experiences can proactively affect our behaviours.注意神經影像機器學習記憶無意識attentionneuroimagingmachine Learningmemoryunconsciousness
