Cognitive Development During Adolescence

519
During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...

We introduce a semi-automatic protocol for shape analysis on brain structures, including image segmentation using open software, and further group-wise shape analysis using an automated modeling package. Here, we demonstrate each step of the 3D shape analysis protocol with hippocampal segmentation from brain MR...

Revisionist Views of Adolescent and Adult Cognition01:24

Revisionist Views of Adolescent and Adult Cognition

288
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

Area of Science:

  • Neuroscience
  • Biostatistics
  • Data Science

Background:

  • Analyzing high-dimensional, heterogeneous data from multi-site cohort studies presents challenges in variable selection and prediction.
  • Complex hierarchical structures in data require specialized analytical frameworks.

Purpose of the Study:

  • To extend the Bayesian Integrative Analysis and Prediction (BIP) framework for simultaneous variable selection and outcome modeling.
  • To develop a novel Bayesian Integrative Mixed Modeling (BIPmixed) framework for multi-view nested hierarchical data.
  • To apply BIPmixed to the Adolescent Brain Cognitive Development (ABCD) Study for behavioral outcome prediction.

Main Methods:

  • Developed the Bayesian Integrative Mixed Modeling (BIPmixed) framework.
  • Incorporated 2-level nested random effects for enhanced interpretability and prediction in hierarchical data.
  • Applied BIPmixed to multi-view data (structural/functional MRI, early life adversity) from the ABCD Study.

Main Results:

  • BIPmixed effectively integrates multi-view data while accounting for nested sampling structures.
  • Simulation studies demonstrated the robustness of BIPmixed across different random effect settings.
  • Identified relevant variables and predicted behavioral outcomes in the ABCD Study.

Conclusions:

  • BIPmixed is a valuable tool for analyzing large-scale studies with complex, hierarchical, and multi-view data.
  • The framework enhances variable selection and prediction accuracy in nested data settings.
  • Facilitates robust analysis of complex cohort studies like the ABCD Study.
