Attention is a very basic function that often is a precursor to all other neurological/cognitive functions. As is frequently the case, clinical models of attention differ from investigation models.
During the deep learning era, attention mechanism was developed to solve similar problems in encoding-decoding. [1]In machine translation, the seq2seq model, as it was proposed in 2014, [24] would encode an input text into a fixed-length vector, which would then be decoded into an output text.
Attention seeking, behavior which is intended to attract attention from others; Attention span, the amount of time a person can concentrate on a single activity; Selective attention, the process by which only a subset of stimuli received by our sensory organs are selected to enter the consciousness

[1] [2] This can be in the form of three different subtypes: positive constructive daydreaming, guilty fear of failure, and poor attentional control.
Specifically, research on attentional capture has two modes: voluntary and reflexive. The voluntary mode is a top down approach where attention is shifted according to high-level cognitive processes. The reflexive mode is a bottom up approach where attention shifts involuntarily based on a stimulus's attention attracting properties. [40]
