• Attention is not a concept researchers fully agree on. What is attention? “No one knows what attention is” (Homel et al, 2019)

Attention in Psychology and Neuroscience

  • In its simplest, most generic form , atttention is an overall level of alertness or ability to engage with one’s surrounding.
  • Attention can also be related to sensory input. Note to self: is sensory attention different on neurodivergent individuals?
  • Sensory inputs habve different dimensions - e.g. spatial attentionand spatial feature attention.
  • Attention is also related to executive function.
  • When executing a task, attention is highly influenced by history (working memory) and context. This is not a feature of LLMs alone.
  • Since working memory is limited, the brain has to dynamically select which parts of the input that are relevant for the task at hand.
  • Evidence suggests attention in memory encoding is strong (Aly and Truke-Browne, 2017)
  • Memory degrades when individuals execute a main task while trying to engage on a secondary task
