About me

Ilja Gabriël Sligte was born and raised in Amsterdam. Favorite things to do besides scientific research: playing bridge (competitively), practicing martial arts (taekwondo), wakeboarding, computer games (shooters, RPGs), eating and drinking.

Research interests

How much information can we keep in mind of what we have just seen? According to traditional theories, quite some information in iconic memory for about half a second after stimulus disappearance, and afterwards only about four objects in visual working memory. Research from our lab (Landman et al., 2003; Sligte et al., 2008, 2009, 2010, 2011) suggests that this two-partite division of visual short-term memory (VSTM) is incorrect. Rather, it seems that people maintain 1)up to 30 objects in a feature-based, iconic memory store for just a few hundred milliseconds after stimulus offset, 2) up to 15 objects in an object-based, fragile VSTM store up to four seconds after stimulus offset, and 3) only about 3-4 objects in an attention-based, sustained working memory store. These different memory stages depend on reverberating activity in primary visual areas (“feature-based”), extrastriate visual cortex (“object-based”), and frontoparietal areas (“attention-based”).
