Making organisms model human behavior: situated models in North-American alcohol research, since 1950

Area of Science:

• Behavioral neuroscience
• Animal models in addiction research

Background:

• Examining validation criteria for nonhuman organisms in North American alcohol addiction research since the 1950s.
• Understanding the challenges in assessing behavioral similarities between humans and nonhuman models.

Observation:

• The field has treated the situatedness of nonhuman organisms as an experimental tool to address model validity.
• Model validity is not solely dependent on standardizing a single organism type, unlike with genetic model organisms.

Findings:

• Organisms are considered valid models only when their environmental conditions are accounted for.
• Environmental standardization is integral to the modeling process in addiction research.
• Model validity is assessed based on the specific environmental conditions under which organisms are studied.

Implications:

• Highlights the importance of environmental context in animal models of addiction.
• Suggests a shift in how nonhuman organisms are validated for human behavior research.
• Informs future research design for more accurate and context-aware addiction models.
