Colin G. DeYoung is an associate professor of

Minneapolis, Minnesota).[1] His research is in the field of personality psychology and personality neuroscience.[2]

Background

DeYoung earned his A.B. in the Mind, Brain, Behavior program of the History and Science concentration at

Jordan B. Peterson
.

Research

DeYoung's research in personality psychology has examined the theoretical structure of personality and the biological basis of personality.

Models of Personality

In contemporary psychology, the most commonly accepted model of personality structure is the "Big Five" or "

Openness to Experience). Stability is defined by one's maintenance of stability and hypothesized to be related to the neurotransmitter serotonin, while Plasticity is seen in one's adaptability to novelty and hypothesized to be related to the neurotransmitter dopamine.[6][7]
DeYoung has also proposed an expanded classification of the Big Five dividing each of the Big Five into two sub-dimensions. DeYoung, Quilty and Peterson (2007)[8] suggested the following aspects of the Big Five factors:

  • Neuroticism:
    • Volatility - irritability, anger, and difficulty controlling emotional impulses
    • Withdrawal - susceptibility to anxiety, worry, depression, and sadness
  • Agreeableness:
    • Compassion - empathetic emotional affiliation
    • Politeness - consideration and respect for others' needs and desires
  • Conscientiousness:
    • Industriousness - working hard and avoiding distraction
    • Orderliness - organization and methodicalness
  • Extraversion
    :
    • Enthusiasm - positive emotion and sociability
    • Assertiveness - drive and dominance
  • Openness/Intellect (or
    Openness to Experience
    ):
    • Intellect - ingenuity, quickness, and intellectual engagement
    • Openness - imagination, fantasy, and artistic and aesthetic interests

The classification system utilizing these ten aspects allows for nuanced discrimination within the Big Five, which can reveal subtleties in differences in personality domains otherwise undetected.

Biological Basis of Personality

DeYoung et al.'s (2010)

Openness to Experience) was the only member of the Big Five lacking a significant relationship to brain structure volume. However, other research by DeYoung et al. (2009)[10]
has shown that Openness/Intellect is related to brain function in prefrontal cortex.

A helpful overview of 'Personality and the Brain' is provided by Glenn Wilson (2012)[11] while Allen & DeYoung (2016) provide an overview article of 'Personality Neuroscience and the Five-factor model' in the Oxford Handbook of the Five Factor Model of Personality.[12]
