In keeping with the historical focus of this special issue of Hippocampus, this paper reviews
the history of my development of the SPEAR model. The SPEAR model proposes that …

Memories are thought to be stored in neuronal ensembles referred to as engrams. Studies
have suggested that when two memories occur in quick succession, a proportion of their …

Goal-directed memory reactivation involves retrieving the most relevant information for the
current behavioral goal. Previous research has linked this process to activations in the fronto …

Multiple types of memory guide attention: Both long-term memory (LTM) and working
memory (WM) effectively guide visual search. Furthermore, both types of memories can …

Declarative memory retrieval is thought to involve reinstatement of neuronal activity patterns
elicited and encoded during a prior learning episode. Furthermore, it is suggested that two …

Human engagement is a vital test research area actively explored in cognitive science and
user experience studies. The rise of big data and digital technologies brings new …

Memory encoding and memory retrieval are neurally distinct brain states that can be
differentiated on the basis of cortical network activity. However, it is unclear whether …

Sequential working memory, the ability to actively maintain sequential information, is
essential for human cognition. The neural representation of each item in sequential working …

When we recall a past event, we reconstruct the event based on a combination of episodic
details and semantic knowledge (eg, prototypes). Though prototypes can impair the veracity …

The ability to coactivate (or “superpose”) multiple conceptual representations is a
fundamental function that we constantly rely upon; this is crucial in complex cognitive tasks …
