Introduction
Attention is important in everyday living. To process abundant information in the environment in the most efficient way with limited cognitive resource, we use selective attention which requires allocating attention to relevant information and ignoring irrelevant information. Inhibiting task-irrelevant information is crucial for optimal processing. Cognitive control refers to a mechanism that enables us to adapt to conflict in task performance and provides the best cognitive strategy to resolve the conflict. We question how the cognitive control system operates in task performance that requires inhibition of distractor, flanker task in this research, and whether the conflict resolution relies on a single central process or on a collection of independent control mechanisms that handle different types of conflict.
We intend to reveal some of the basic features of inhibition process for better understanding of cognitive control. Here are some characteristics of inhibition process proposed by various researchers. Conflict adaptation depends on task structure (Arcay and Hazeltine, 2011). How the task is structured is crucial to the control mechanism recruited for the task. This is also related to the task presentation. That is, whether participants think they’re doing one kind of task or several different types of tasks matters. Cognitive control mechanism also depends on the type of conflict. That is, origin of conflict- whether it’s stimulus or response based– matters. Knowing that the conflict stems from response and stimulus in Simon and Stroop task each, researchers combined Stoop task and Simon task to verify their arguments (Egner, Delano and Hirsch, 2007). They concluded that one control mechanism used in one type of conflict is not recruited for the resolution of the other type of conflict. That is, cognitive control is not centralized; it rather works in a context-sensitive way.
