Final answer:
The modularity principle is a fundamental concept in experimental neuropsychology that suggests the brain is composed of different specialized modules. These modules work together to process information and carry out complex cognitive processes.
Step-by-step explanation:
The modularity principle is a fundamental concept in experimental neuropsychology. It suggests that the brain is composed of different modules or specialized areas, each responsible for specific functions. These modules work together to process information and carry out complex cognitive processes.
For example, one module may be responsible for language processing, another for visual perception, and another for motor control. This modular organization allows for efficient and specialized processing in the brain.
This principle has been supported by studies using techniques such as brain imaging and lesion studies, which have shown that damage to specific brain areas can result in selective impairments in specific functions.
