First, we demon- strate that a connectionist model of infant categorization based number and type of categories formed is modulated by the on a self-organizing map (Gliozzi, Mayor, Hu, & Plunkett, 2009) predicts an increased influence of the first and the last stimuli during familiarization on the category boundaries. We then present data from 10-month-old infants which confirm recency effects. these effects. Future research will allow to discriminate be- tween a primacy or a recency effect.
