When we point at an object, the toddler focuses on the object, while the dog usually takes the gesture as a directional cue. In a recent study, researchers from the Department of Ethology at E\u00f6tv\u00f6s Lor\u00e1nd University find explanations for this phenomenon. It appears that the discrepancy is not only due to how dogs see, but may, in fact, reflect how they think. For \u201csmarter\u201d dogs, the appearance of an object matters as much as its location, suggesting that their information processing is more similar to that of humans.<\/strong><\/p>\n

When we point at an object, the toddler focuses on the object, while the dog usually takes the gesture as a directional cue. In a recent study, researchers from the Department of Ethology at E\u00f6tv\u00f6s Lor\u00e1nd University find explanations for this phenomenon. It appears that the discrepancy is not only due to how dogs see, but may, in fact, reflect how they think. For \u201csmarter\u201d dogs, the appearance of an object matters as much as its location, suggesting that their information processing is more similar to that of humans.<\/strong><\/p>\n

Spatial bias is the phenomenon of interpreting information in relation to space, location or distance when the same information could easily apply to an object. \u201cThis is manifested, for example, in the way dogs and children react to gestures when we show them the position of an object. Very early on, children interpret the gesture as pointing to the object, while dogs take the pointing as a directional cue. In other words, regardless of the intention of the person giving the cue, the meaning for children and dogs is different. This phenomenon has previously been observed in dogs using a variety of behavioural tests, ranging from simple associative learning to imitation, but it had never been studied per se,\u201d explains Ivaylo Iotchev<\/strong>, first author of the study, which appears in the journal Ethology<\/em>.<\/p>\n

\n

The researchers have concluded that the spatial bias is an untapped opportunity to better understand how dogs think.<\/p>\n<\/blockquote>\n

Previous research has not clarified whether dogs behave this way because they have inferior vision compared to primates, or whether it is actually an information processing bias, whereby the parameters of the space around them are more important to dogs than the specific, nearby objects.<\/p>\n

The researchers measured spatial bias in two behavioural tests involving 82 dogs. In one task, the dogs had to learn, over a maximum of 50 trials, whether the treat was always on the right or left plate, so they learned a location. In the other task, two types of plates were used, a white round one and a black square one, these were always placed in the middle. A dog was always given only one type of plate to eat from but was exposed to each in a semi-random sequence. In this constellation,  they were learning about the properties of the plate. Learning was measured  by how fast a dog ran to the correct plate. The results showed that the animals learned faster when the treat was placed to the right or left, so they had to choose which direction to go. They had more difficulty remembering whether the treat was on the white round or black square plate. The \u2018spatial bias\u2019 measure described how much faster the dogs were at learning about the place than at learning about object features. A more complicated task followed if the dogs had already learned where the treat was because then the situation was reversed. That is, if they had previously received the treat on the right, it was now on the left in the new position, and if it had been on the white plate, it was now on the black plate.<\/p>\n

To find out whether spatial bias is sensory, cognitive or mixed, the researchers needed to detect and measure differences between the visual and cognitive abilities of dogs.<\/p>\n<\/blockquote>\n

This involved measuring how short the dog\u2019s head is \u2013 as this is correlated with visual acuity \u2013 and also measuring how efficiently they solve problem tasks.<\/p>\n

The head shape was investigated by Zs\u00f3fia Bogn\u00e1r <\/strong>PhD student and co-author of the study. \u201cThe visual abilities of dog breeds differ from each other, which indirectly results from their head shape. Dogs with shorter heads \u2013 scientifically known as brachycephalic \u2013 develop human-like vision. The structure of their retina implies sharper and more focused vision than their longer-headed counterparts. This has allowed us to use a measure of head shape (the so-called \u201ccephalic index\u201d) as an approximate measure of the quality of vision in dogs. It is calculated by dividing the width of the skull by the length of the skull. The shorter the head, the higher the number\u201d, explained Zs\u00f3fia Bogn\u00e1r<\/strong>.<\/p>\n

To measure cognitive ability, the dogs took part in a series of tests. \u201cWe tested their memory, attention skills and perseverance. We found that dogs with better cognitive performance in the more difficult spatial bias task linked information to objects as easily as to places.<\/p>\n

\n

We also see that as children develop, spatial bias decreases with increasing intelligence,\u201d<\/p>\n<\/blockquote>\n

adds Eniko Kubinyi<\/strong>, head of the MTA- \u2019Lend\u00fclet\u2019 Momentum Companion Animal Research Group.<\/p>\n

The study found that spatial bias is smaller in dogs with better visual acuity and who are \u201csmarter\u201d. \u201cSpatial bias in dogs is not simply a sensory problem but also a mindset. We also found that \u2018smarter\u2019 dogs are resilient in difficult learning situations and can overcome their biases,\u201d concludes Iotchev<\/strong>.<\/p>\n
