Visual short-term memory maintenance and retrieval in children and adults
Investigators: Duncan Astle, Bo-Cheng Kuo, Gaia Scerif, Kia Nobre Department of Psychology, Royal Holloway; Department of Experimental Psychology, Oxford
Studies using fMRI and EEG/ERPs have shown that visual short-term memory (VSTM) is partly supported by activity in visual areas, and that representations maintain a spatiotopic layout. In this study, MEG is used to investigate how tonic and oscillatory neural signals in perceptual areas, as well as their correlation with neural signals in multisensory associative cortices, contribute to maintenance and retrieval of information in VSTM. Furthermore, the study will investigate the relationship between these neural measures and differences in memory performance over development and between individuals.
