The three accounts of the neural
basis of an advance in behavioral abilities in infants. Here is an explanation
of each of the three accounts based on the information provided:
1.     Maturational View:
- The
     maturational view proposes that the neuroanatomical maturation of specific
     brain regions, such as the dorsolateral prefrontal cortex (DLPC), plays a
     crucial role in the emergence of new behavioral abilities in infants.
- According to
     this view, successful performance in tasks such as object retrieval is
     attributed to the maturation of a particular brain region, rather than
     changes in interactions between multiple regions.
- The
     maturational perspective suggests that the development of specific brain
     regions at certain stages allows for the acquisition of new skills and
     behaviors in infants.
2.     Interactive Specialization View:
- The
     interactive specialization view emphasizes the importance of changes in
     interactions between multiple brain regions that are already partially
     active in supporting the advancement of behavioral abilities in infants.
- This
     perspective suggests that the refinement of connectivity between regions,
     rather than within a single region, is critical for the emergence of new
     cognitive functions.
- According to
     this view, regions of the brain adjust their functionality together to
     enable new computations and support the development of complex behavioral
     abilities in infants.
3.     Skill-Learning Model:
- The
     skill-learning model posits that the pattern of activation of cortical
     regions changes during the acquisition of new skills throughout the
     lifespan, including in infants.
- This model
     suggests that during skill acquisition, there is greater activation of
     frontal regions initially, followed by a shift towards greater activation
     of posterior regions as the skill is mastered.
- The
     skill-learning model highlights the dynamic changes in cortical activation
     patterns that occur during the acquisition of new skills, indicating a
     reorganization of brain activity as infants develop and refine their
     behavioral abilities.
In summary, the three accounts of the neural basis
of an advance in behavioral abilities in infants - the maturational view,
interactive specialization view, and skill-learning model - provide different
perspectives on how neural maturation, inter-regional interactions, and skill
acquisition processes contribute to the development of cognitive functions and
behavioral abilities in infants. These accounts offer valuable insights into
the complex mechanisms underlying infant cognitive development and the neural
basis of emerging skills during early life.
