Research says some dogs may be “very sensitive” to lies

There are two opaque buckets at the beginning of the test. The test subject was a dog (domestic dog), showing that food was placed in one of two buckets by an experimenter (human). The second experimenter removed the food (from one bucket to another). Finally, a communicator (also a human) gives the dog a suggestion about which bucket it should choose to find food.

The test system includes different types of dogs, including Schnauzers, Morosod, Swiss Mountain Dogs or Cattle Dogs. Experiments also include retrievers and terriers. They found that terrier dogs in the TB group more often followed the communicator’s advice alone than in the FB group.

The first thing to do is the TB test. The communicator points to the empty bucket, and all dog breeds seem to be looking for the bucket the communicator points to. The FB test was conducted for the second time, and the communicator was also directed to the empty bucket. Most dogs still go to the barrel pointed to by the communicator.

In each experiment, the dog saw the food in the bucket. They always know (or think they know) which bucket contains food. It is also important that after showing each dog where the food is in one of the two buckets, the food is “secretly removed”, so when a choice needs to be made, there is actually no food in both buckets . According to the research, “dogs seem to have not noticed that the food was removed because they still made a choice”.

In the FB test, the terrier seems to be the only dog ​​breed that always makes the opposite decision to other dog breeds. After the direction in the first TB test caused the dog to find an empty bucket, the terrier tended to negate the communicator’s instructions in the subsequent FB test and choose another bucket. This does not mean that terriers are the only dog ​​breeds that can distinguish between true and false beliefs in humans. This does mean that terriers are dogs that “behave in a similar paradigm like human babies and apes in previous studies.”

Once the terrier starts to distinguish itself from other dog breeds in the experiment of this project, the terrier will be compared with the border collie. Border collies have been “extensively tested in social cognition research” and are “cooperative workers”, while terriers are considered “independent workers”.

Although it is possible for both breeds to detect human deception, terriers (independent workers) are more likely to choose buckets with food in them than border collies (cooperative workers) (regardless of the order What is it). The researchers hypothesized that “cooperative workers” simply interpret the first bucket point as the communicator’s desire to take the dog to a new or unknown place. “Independent workers” (terriers in this case) were thought to be likely to feel misled and thus denied the communicator in subsequent tests.

Researchers support that whether any dog ​​can interpret the true or false intention of the communicator is not an absolute conclusion.
