Consistent Individual Behavioral Variation: The Difference between Temperament, Personality and Behavioral Syndromes.

Area of Science:

• Ethology
• Animal Behavior
• Behavioral Ecology

Background:

• Ethologists frequently use
• personality,
• temperament,
• and behavioral syndromes
• interchangeably.
• This inconsistent terminology hinders the study of consistent individual differences in animal behavior.
• Lack of precise definitions creates confusion across research fields and levels of variation.

Purpose of the Study:

• To investigate the distinctions and overlaps in the usage of
• personality,
• temperament,
• and behavioral syndromes.
• To identify sources of terminological confusion in animal behavior research.
• To propose a framework for defining these terms based on levels of behavioral variation.

Main Methods:

• A rapid, non-exhaustive, and repeatable literature search strategy was employed.
• Analysis focused on identifying unique distinctions and overlaps in the usage of key terms.
• A framework was developed to categorize and define terms based on variation levels.

Main Results:

• Three primary areas of terminological confusion were identified: outdated historical usage, imprecision between disciplines, and lack of precision regarding variation levels.
• The study highlights the need for clearer definitions to advance the study of consistent individual differences in behavior.
• A framework was proposed to differentiate terms based on variation in behavior across individuals, populations, and contexts.

Conclusions:

• Formalizing a framework for understanding consistent individual animal behavioral variation can resolve terminological ambiguity.
• Clearer definitions of
• personality,
• temperament,
• and behavioral syndromes
• will enhance the study of animal behavior.
• The proposed framework provides a structured approach to defining and understanding behavioral variation in animals.
