ASD-similar social behaviour scores affect stimulus generalization in family dogs.

Generalization, the tendency to respond in the same way to different but similar stimuli, is one of the main cognitive abilities that make category formation possible and thus is a prerequisite for efficiency in learning. Individuals with autism spectrum disorder (ASD) experience pervasive difficulty with producing generalized responses across materials, people, places, and contexts. Increasing evidence suggests that "ASD-like" social impairments appear endogenously and spontaneously in family dogs providing a high-validity model for understanding the phenotypic expression of human ASD.

Intranasal Oxytocin Improves Social Behavior in Laboratory Beagle Dogs () Using a Custom-Made Social Test Battery.

For a long time, oxytocin has been thought to have a generally positive effect on social cognition and prosocial behavior; however, recent results suggested that oxytocin has beneficial effects only under certain conditions. The aim of the present study was to explore potential associations between social competence and the effect of intranasal oxytocin on the social behavior of laboratory beagle dogs. We expected oxytocin treatment to have a more pronounced positive effect on dogs with lower baseline performance in a social test battery.

Comparison of Behavior and Genetic Structure in Populations of Family and Kenneled Beagles.

In dogs, the social and spatial restriction associated with living in a kennel environment could lead to chronic stress and the development of abnormal behaviors ("kennel-dog syndrome"). However, little is known about how kenneled dogs differ from their conspecifics living as pets in human families. In the current study, using a test battery exposing the dogs to novel stimuli, we compared the behavior of three groups of beagles: (1) kenneled dogs living in a restricted environment with limited human contact ( = 78), (2) family dogs living in human families as pets ( = 37), and (3) adopted dogs born in the kenneled population but raised in human families ( = 13).

Auditory⁻Visual Matching of Conspecifics and Non-Conspecifics by Dogs and Human Infants.

We tested whether dogs and 14⁻16-month-old infants are able to integrate intersensory information when presented with conspecific and heterospecific faces and vocalisations. The looking behaviour of dogs and infants was recorded with a non-invasive eye-tracking technique while they were concurrently presented with a dog and a female human portrait accompanied with acoustic stimuli of female human speech and a dog's bark. Dogs showed evidence of both con- and heterospecific intermodal matching, while infants' looking preferences indicated effective auditory⁻visual matching only when presented with the audio and visual stimuli of the non-conspecifics.

Social learning of goal-directed actions in dogs (Canis familiaris): Imitation or emulation?

A goal-directed action is composed of two main elements on which the observer may focus its attention: the movement performed (i.e., the action) and the outcome (i.

Dogs (Canis familiaris) adjust their social behaviour to the differential role of inanimate interactive agents.

Dogs are able to flexibly adjust their social behaviour to situation-specific characteristics of their human partner's behaviour in problem situations. However, dogs do not necessarily detect the specific role played by the human in a particular situation: they may form expectations about their partners' behaviour based on previous experiences with them. Utilising inanimate objects (UMO-unidentified moving object) as interacting agents offers new possibilities for investigating social behaviour, because in this way we can remove or control the influence of previous experience with the partner.

An Investigation on Social Representations: Inanimate Agent Can Mislead Dogs (Canis familiaris) in a Food Choice Task.

The nature of mental representation of others plays a crucial role in social interactions. Dogs present an ideal model species for the investigation of such mental representations because they develop social ties with both conspecifics and heterospecifics. Former studies found that dogs' preference for larger food quantity could be reversed by humans who indicate the smaller quantity.

What are you or who are you? The emergence of social interaction between dog and an unidentified moving object (UMO).

Robots offer new possibilities for investigating animal social behaviour. This method enhances controllability and reproducibility of experimental techniques, and it allows also the experimental separation of the effects of bodily appearance (embodiment) and behaviour. In the present study we examined dogs' interactive behaviour in a problem solving task (in which the dog has no access to the food) with three different social partners, two of which were robots and the third a human behaving in a robot-like manner.
