Overview

The science of personalized value development through adolescence: integration of brain, real-world, and life-course approaches

Purpose of the Research Project

Our project aims at establishing an interdisciplinary scientific field that will be dedicated to the development of "personalized value" through adolescence by integrating brain, real-world, and life-course approaches.

Human adolescence is far longer than that in non-human primates and is the life stage in which the cerebral neocortex matures. While childhood is associated with trans-generational incorporation of parental values, adolescence is characterized by social interactions with peers. Through such influences, a person's value is internalized and personalized to become "personalized value".

Content of the Research Project

A01 aims at uncovering the neural basis of personalized value. Here, value development can be modeled as the psychological process in which adolescents acquire the ability to control the conflict between value memory and actual behavior by using self-regulation, including meta-cognition and language (inner-speech).

B01 considers the "real-world" as a modulatory factor in the neural basis of value development. Here, we propose a spiral model where active interactions with the real-world influence value development, which then shapes patterns of action in life, in turn inducing plasticity in the brain circuit.

C01 will use life-course epidemiology to understand how personalized value is developed in adolescence and how it influences later life. The Tokyo TEEN Cohort will be the main studied population.

By integrating brain (A01), real-world (B01), and life-course (C01) approaches, D01 will deepen the conceptual framework of personalized value. We will then develop psychosocial intervention strategies to evolve personalized value.

Expected Research Achievements and Scientific Significance

Our project will propose a new interdisciplinary science of the "action brain", where we clarify how the brain evolves personalized value through adolescence to actively influence the social environment and pursue subjective well-being. Our findings will ultimately contribute to policy-making concerning education and health promotion in adolescence.

Key Words

Adolescence: a developmental stage from the onset of puberty through maturation of the neocortex.
Personalized value: a person's inner drive for long-term action, which will be internalized and personalized through adolescence.
