DESCRIPTION:The Simultaneous Type/ Serial Token (STST) model of temporal a
 ttention and working memory (Bowman & Wyble\, 2007) was published over 10 
 years ago as a theory of the attentional blink and associated phenomena. I
 n the intervening period\, the scope of the theory has grown\, becoming a 
 theory of the episodic nature of attention and perception (Wyble et al\, 2
 011). Recently\, we have also been considering the implications of the STS
 T model for theories of conscious perception. If one interprets the neural
  network model that implements the STST theory literally\, it makes two pa
 rticular predictions for conscious experience: 1) that we can pre-consciou
 sly search our sensory environments for salient stimuli (type-information)
 \; and 2) that we cannot pre-consciously search our sensory environment on
  the basis of episodic information (token-information). The latter of thes
 e fits well with theories of conscious perception based upon event individ
 uation (Kanwisher\, 2001).\nUsing rapid serial visual presentation\, I wil
 l report a series of EEG (Bowman et al\, 2014) and behavioural (Aviles et 
 al\, 2020) experiments that provide evidence in support of these two predi
 ctions. These experiments focus on the fragility\, even absence\, of memor
 y for fleetingly presented stimuli. We argue that these findings provide s
 upport for a theory we call the tokenised percept hypothesis.\n\nAvilés\,
