Sensory Prediction and Repetition Suppression in the tactile modality as early markers of executive attention development at preschool age

International audienceThe tactile modality, the first to develop, is the foundation of cognitive development. Sensory Prediction (SP) is a core mechanism sustained by our perceptions and allows the brain to anticipate future stimulations on the basis of previous sensory inputs (Friston, 2005). Repetition Suppression (RS) refers to the reduction of activity in the brain when a predicted stimulus is repeated or becomes irrelevant. Sensory Prediction in the tactile modality was suggested as an early precursor of cognitive development (Dumont et al., 2022). Predictive mechanisms may form the basis of executive attention development by sustaining self-regulation processes such as habituation or anticipation (Bubic et al., 2010).The aim of this study is to investigate how tactile prediction and other tactile processing phenomena are related to executive attention development at preschool age
