Human-Animal Interactions: Vets and Animal Scientists

Human-Animal Interactions: Vets and Animal Scientists

Introduction to Human-Animal Interactions (HAIs)

  • Ancient depictions of human-animal interactions exist, such as images from Los Cabollos (Spain) and Lascaux Cave (France) dating from c. 30000 – 10000 ext{ BCE}, showing humans and deer in hunting scenes.

  • This topic is crucial for veterinarians and animal scientists.

Learning Objectives

  • Define Human-Animal Interactions (HAIs) and provide diverse examples.

  • Identify the three basic types of HAIs (positive, neutral, negative) and methods for their measurement.

  • Differentiate between HAIs, Human-Animal Relationships (HARs), and Human-Animal Bonds (HABs).

  • Explain both the positive and negative impacts of HAIs on humans and animals.

  • Describe the essential role of veterinarians and animal scientists in the context of HAIs.

Background to Human-Animal Interactions

  • Human-Animal Interactions is a relatively new academic field of study.

  • It encompasses two primary academic approaches:

    • Human-Animal Studies (HAS): A humanities-based approach.

    • Anthrozoology: A scientific approach.

  • Both methodologies offer significant insights into understanding HAIs.

What is a Human-Animal Interaction (HAI)?

  • An HAI is defined as an encounter between two individuals, one human and one animal.

  • These encounters can be multi-sensory.

  • Examples of HAIs include:

    • Interactions with pets/companion animals.

    • Interactions with livestock (e.g., farm animals).

    • Interactions with working animals (e.g., police dogs, assistance animals).

    • Interactions in entertainment and recreational settings (e.g., horse riding).

    • Interactions in Animal-Assisted Interventions (AAIs).

    • Interactions with wildlife (e.g., observing animals in their natural habitats or in zoos).

Three Types of HAIs

HAIs are categorized into three basic types based on their emotional and behavioral impacts:

  • Positive HAIs:

    • Both the human and the animal perceive each other positively.

    • There is an absence of fear from either party.

    • Confidence is present between the human and animal.

    • The interaction is perceived as pleasurable for both.

  • Neutral HAIs:

    • These interactions lack any discernible positive or negative emotional impact.

    • Neither party exhibits a strong behavioral response.

    • No notable excitement, fear, aggression, affection, or any other strong emotional or behavioral reaction is typically associated with neutral HAIs.

  • Negative HAIs:

    • During these interactions, the human or animal is perceived as frightening.

    • Unpleasant emotions are generated.

    • This leads to aversive behaviors such as avoidance or aggression from either party.

How to Measure a HAI from an Animal's Perspective

Measuring an HAI from an animal's viewpoint typically involves assessing three categories of responses:

  • Behavioral Responses: Observing changes in an animal's actions, posture, vocalizations, or movements.

  • Physiological Changes: Measuring biological indicators such as heart rate, cortisol levels (stress hormones), respiration rate, or body temperature.

  • Cognitive Changes: Assessing mental states, learning patterns, or responses to stimuli that indicate an animal's perception or anticipation.

Human-Animal Relationships (HARs)

  • A Human-Animal Relationship (HAR) develops over time when animals frequently contact humans.

  • Through repeated interactions, animals begin to anticipate the nature of future HAIs.

  • HARs are dynamic processes, continually reinforced by subsequent interactions.

  • Like HAIs, HARs can be positive, neutral, or negative.

  • These relationships are particularly common and studied in agricultural, research, and zoo animals due to their regular human contact.

  • Factors influencing HARs include:

    • Animal factors: Proximity to humans; the animal's ability to recognize human social cues; species-specific characteristics; previous experiences with humans; individual temperament; and the environment.

    • Human factors: Cultural factors influencing human perceptions and behaviors towards animals; and previous experiences humans have had with animals.

Benefits of Positive HARs
  • For Humans:

    • Increased job satisfaction, morale, motivation, and self-worth.

    • Reduced injury and stress during animal handling.

  • For Animals:

    • Long-lasting positive effects on animal welfare.

    • Greater productivity and ease of handling.

    • Lower risk of injury to animals.

    • Can buffer the stress of necessary aversive procedures (e.g., veterinary examinations, vaccinations).

Negative HARs in Farm, Zoo, and Research Animals
  • Poor animal welfare: Manifests as acute and chronic stress, leading to increased cortisol levels, elevated heart rate, and reduced oxytocin production.

  • Impaired growth and immunity: Observed in research animals subjected to negative HARs.

  • Reduced productivity: A common outcome in farm animals experiencing negative HARs.

  • Chronic stress: Frequently seen in captive wildlife in zoo animals with negative HARs.

Summary of Human-Animal Relationships (HARs)
  • HARs develop over time from frequent human-animal contact, leading to anticipation of future interactions.

  • They are most commonly described and studied in agricultural, zoo, and research animals.

  • A positive HAR is directly correlated with a positive animal welfare state.

  • A negative HAR is directly correlated with a negative animal welfare state.

Human-Animal Bonds (HABs)

  • The Human-Animal Bond (HAB) represents a deeper progression, evolving from repeated positive HAIs into a positive HAR, and ultimately forming a HAB.

  • Definition (AVMA - American Veterinary Medical Association): A HAB is
