What is the overall aim of cognitive neuroscience?

The correct answer highlights the primary objective of cognitive neuroscience, which is to understand how brain function is linked to cognitive processes. This field combines principles from both psychology and neuroscience, providing insights into how the brain's structure and activity relate to aspects such as perception, memory, language, and decision-making. By studying brain mechanisms, cognitive neuroscience aims to create a comprehensive understanding of how these biological processes influence thoughts and behaviors.

The other options represent different focuses that do not align with the core aim of cognitive neuroscience. For instance, developing social theories pertains more to social psychology, while focusing solely on the treatment of mental disorders is more relevant to clinical psychology. Analyzing the behavior of large groups is the domain of social psychology and behavioral studies, which do not involve the direct exploration of brain activity in relation to cognitive functions.
