Lapsley-PlotThickens-2016

The review focuses on Dan P. McAdams's work, "The Art and Science of Personality Development."
It is authored by Daniel Lapsley and published in Human Development, detailing the relationship between personality and its development.

Historically, personality psychology focused on stable individual differences using trait models.
Developmental psychology concentrated on changes within individuals over time, often neglecting personality stability.
Loevinger’s theory introduced the concept of ego development, bridging the gap between stable traits and individual development.
- Ego development considered a key trait, essential for understanding personal differences alongside intelligence.

By the 1980s, developmental and personality psychology began exploring their intersections more closely.
Lapsley highlights how developmental science differed in terminology and approach compared to personality theories.
Damon’s work on personality development emphasized individuality and social relationships, contributing to the developmental foundations of personality.

McAdams's book is noted for its comprehensive exploration of diverse topics related to personality development.
- It synthesizes various fields: neuroscience, genetics, and culture, providing a broader context for personality research.
- Addresses developmental foundations of personality traits, particularly emphasizing the significance of the "5-7 shift" in childhood.

Personality evolves as a response to social needs, crucial for societal functionality and cooperation.
Variations in personality traits help individuals navigate social interactions.

McAdams argues that developing personality is a creative performance, akin to theatrical expression.
- This performance evolves into narrative identity, where individuals author their stories.

Personality development integrates biological, psychological, and social influences.
Traits originate from biological temperament and adapt through social experiences.

Over time, the self matures, incorporating layers: as an actor, an agent, and finally an author, shaping personal narratives.
- Distinct phases of personality comprise identifiable features from childhood through young adulthood.

Lapsley notes a misalignment in the timeline of ego development as described by McAdams, individually noting the I-self versus Me-self development.

The metaphor of personality layering needs clarification in dynamic interactions among traits and personal motives.
- Lapsley suggests deeper integration between personality aspects, rather than viewing them as separate entities.

A noticeable absence of discussion on social cognition in personality development, despite its significance.
- The author could benefit from including this aspect in further editions for a holistic understanding.

Lapsley raises points about McAdams's view on morality, indicating a need for nuance regarding moral socialization versus general social rules.
Suggests extending insights on narcissism and agency in the context of developmental challenges, particularly during adolescence.

McAdams's book serves as a vital resource for examining the intersection of personality and development in psychology.
By calling attention to narrative identity and the integration of personality traits, the work sets a foundation for continued scholarly dialogue between developmental and personality psychology.
