The maturational perspective is a theory in
developmental neuroscience that focuses on the relationship between neural
maturation and the emergence of sensory, motor, and cognitive functions during
human development.
1. Theory Overview:
- The
maturational perspective posits that the development of specific regions
of the brain, particularly the cerebral cortex, is closely linked to the
acquisition of new sensory, motor, and cognitive abilities.
- According to
this theory, the maturation of distinct brain regions at different stages
of development is responsible for the emergence of age-appropriate
behaviors and functions.
2. Neural Maturation and Behavior:
- The theory
suggests that the anatomical maturation of cortical regions is a key
determinant of when specific functions will become functional.
- Success in
new behavioral tasks at certain ages is attributed to the maturation of
corresponding brain regions, leading to the development of age-appropriate
skills and abilities.
3. Example: Visual Orienting and Attention:
- One example
provided in the articles relates to the neurodevelopment of visual
orienting and attention.
- Researchers
argue that control over visually guided behavior initially involves
subcortical structures but shifts to posterior cortical regions and
eventually to anterior regions with age and development.
- The
characteristics of visually guided behavior in human infants during the
first month of life resemble those observed in adult primates with
cortical damage, supporting the maturational perspective.
4. Comparison with Adult Lesions:
- The
maturational perspective often involves comparing the behavioral
performance of adults with acquired brain lesions to behaviors observed
during infancy.
- By examining
how specific brain regions mature and contribute to functional abilities,
researchers can gain insights into the neural basis of cognitive
development.
5. Limitations and Considerations:
- While the
maturational perspective provides valuable insights into the relationship
between neural maturation and behavior, it may not fully account for the
dynamic changes in patterns of cortical activation observed during
postnatal development.
- Factors such
as environmental influences, experience, and interactions between brain
regions are also important considerations in understanding human
functional brain development.
In summary, the maturational perspective theory in
developmental neuroscience emphasizes the role of neural maturation in shaping
the emergence of sensory, motor, and cognitive functions during human
development. By examining the maturation of specific brain regions and their
contributions to behavior, researchers can gain a better understanding of the
neural mechanisms underlying cognitive development in infants and children.
