Processes of Personality Development in Adulthood: The TESSERA Framework

Area of Science:

• Psychology
• Developmental Psychology
• Personality Psychology

Background:

• Personality development is a continuous process throughout adulthood.
• Existing theories often lack a clear link between short-term situational processes and long-term personality change.
• Understanding the mechanisms of personality continuity and change is crucial.

Purpose of the Study:

• To present a novel theoretical framework, TESSERA, for understanding adult personality development.
• To explicate the interplay between short-term situational processes and long-term personality development.
• To provide a framework applicable to various personality characteristics and developmental trajectories.

Main Methods:

• Theoretical development of the TESSERA framework.
• Conceptual analysis of short-term (situational) and long-term (developmental) processes.
• Illustration of the framework's application to normative and differential personality development.

Main Results:

• The TESSERA framework integrates short-term situational processes (Triggering situations, Expectancy, States/State expressions, Reactions) into long-term personality development.
• Reflective and associative processes on these sequences drive continuity and lasting changes in personality.
• The framework enhances understanding of personality development across the lifespan.

Conclusions:

• The TESSERA framework offers a comprehensive model linking micro-level situational processes to macro-level personality development.
• It extends previous theories by detailing the recursive nature of personality change and its various manifestations.
• The framework is broadly applicable to diverse personality characteristics and individual differences in development.
