Attentional control

There are two types of attention that can be pointed out from the literature on the subject. Sasin and Fougnie (2021) suggest that bottom-up and top-down attention represent an essential dichotomy that cannot be ignored if one expects to pick up every stimulus or achieve the goals. In the case of top-down attention, the process of collecting information occurs voluntarily. As for bottom-up attention, a person might redirect their efforts when affected by salient stimuli (Riddle et al., 2019). Therefore, such an approach represents a response to unexpected impetuses that, nonetheless, force the individual to resort to their experience. Table 1 can be examined for a list of examples related to both bottom-up and top-down attention categories.
