Would dogs copy irrelevant actions from their human caregiver?

Area of Science:

• Comparative psychology
• Ethology
• Animal behavior

Background:

• Companion dogs exhibit sophisticated social learning from humans.
• Overimitation, copying causally irrelevant actions, is observed in humans but not great apes.
• Social factors like affiliation and conformity are hypothesized to drive human overimitation.

Purpose of the Study:

• To investigate whether pet dogs exhibit overimitation, a behavior considered uniquely human.
• To explore if dogs copy causally irrelevant actions demonstrated by their caregivers.
• To determine if the presence of causally relevant actions influences the copying of irrelevant actions.

Main Methods:

• Dogs observed caregivers demonstrating actions, some causally relevant (leading to food) and some irrelevant.
• The sequence of demonstrated actions (irrelevant alone, or before/after relevant actions) was varied.
• The frequency of dogs replicating the causally irrelevant action was recorded.

Main Results:

• Approximately half of the dogs replicated the causally irrelevant action demonstrated by their caregiver.
• The frequency of replicating irrelevant actions remained similar regardless of whether they were shown alone or adjacent to relevant actions.
• The demonstration of a causally relevant action did not inhibit the copying of a spatially and functionally separate irrelevant action.

Conclusions:

• Results provide evidence for overimitation in domestic dogs.
• This finding challenges the notion that overimitation is a uniquely human social learning trait.
• Domestication and enculturation may facilitate advanced social learning, including overimitation, in dogs.
