Conflict Adjustment is Modulated by Conflict Similarity

Image
People receive a large amount of information input every day, and when there is inconsistency in the information, cognitive conflict arises. When this conflict repeatedly occurs, people's ability to resolve conflicts improves, and this phenomenon is called the congruency sequence effect (CSE), which is also commonly referred to as the conflict adaptation effect (CAE). Currently, there are two main theoretical explanations for the congruency sequence effect. One is the top-down theory, which believes that it reflects the dynamic regulatory function of cognitive control, while the other is the bottom-up theory, which believes that it reflects stimulus-based learning or memory. Both theories can explain the congruency sequence effect produced by a single type of conflict. However, in exploring the CSE between two different types of conflicts (such as Stroop and Simon), researchers have found problems with these two theories. When the consecutive trial involves different conflict types...

Cognitive control is modality-specific

Cognitive control refers to the process by which individuals store, plan, and manipulate relevant information based on current task goals. The adaptability of cognitive control plays a crucial role in our ability to flexibly face upcoming events. When we are performing a task with a clear goal but are interfered by task-irrelevant information, our reaction becomes slower and more prone to errors. At this time, we need to invoke cognitive control to make goal-directed responses.      Different types of conflicts require similar processes. Previous research has found that different types of conflict underlie different cognitive control mechanisms. For example, there is no conflict adaptation effect (CAE) between stimulus-stimulus conflicts and stimulus-response conflicts. Some studies have also found that there is no CAE between conflicts in different modalities, but they attributed this result to task switching between visual and auditory conflicts. So, is the separation ...
