IMPLICIT SHORT-TERM MEMORY AND UNCERTAINTY IN VISUOMOTOR INTEGRATION AND TEMPORAL INFORMATION PROCESSING
The context in which we perform an action influences how we perceive and act on a stimulus. One known contextual effect is the serial dependence, in which behavior in the previous trials influences the present behavior. The mechanisms responsible for this influence are not completely understood and are mostly studied through explicit memory tasks. In the present work, we investigated the effects of serial dependence during visuomotor integration, in which the bias is mediated through implicitly acquired memories. We did a series of experiments based on variations of the same target interception task aiming to characterize the serial dependence effect and the memory trace that is responsible for it. We observed that the attractive bias in this task is long-lasting and resistant to interference while it capitalizes on the redundancy of information sourced by different stimulus’ features. We also used electroencephalography (EEG) recordings during the inter-trial interval to investigate the memory traces responsible for the serial dependence effect.
