Children with autism social engagement in interaction with Nao, an imitative robot: A series of single case experiments
Author(s): Adriana Tapus, Andreea Peca, Amir Aly, Cristina Pop, Lavinia Jisa, Sebastian Pintea, Alina S. Rusu and Daniel O. Davidpp.: 315–347 (33)More LessThis paper presents a series of 4 single subject experiments aimed to investigate whether children with autism show more social engagement when interacting with the Nao robot, compared to a human partner in a motor imitation task. The Nao robot imitates gross arm movements of the child in real-time. Different behavioral criteria (i.e. eye gaze, gaze shifting, free initiations and prompted initiations of arm movements, and smile/laughter) were analyzed based on the video data of the interaction. The results are mixed and suggest a high variability in reactions to the Nao robot. The results are as follows: For Child2 and Child3, the results indicate no effect of the Nao robot in any of the target variables. Child1 and Child4 showed more eye gaze and smile/laughter in the interaction with the Nao robot compared to the human partner and Child1 showed a higher frequency of motor initiations in the interaction with the Nao robot compared to the baselines, but not with respect to the human-interaction. The robot proved to be a better facilitator of shared attention only for Child1. Keywords: human-robot interaction; assistive robotics; autism

Using the social robot probo as a social story telling agent for children with ASD
Author(s): Bram Vanderborght, Ramona Simut, Jelle Saldien, Cristina Pop, Alina S. Rusu, Sebastian Pintea, Dirk Lefeber and Daniel O. Davidpp.: 348–372 (25)More LessThis paper aims to study the role of the social robot Probo in providing assistance to a therapist for robot assisted therapy (RAT) with autistic children. Children with autism have difficulties with social interaction and several studies indicate that they show preference toward interaction with objects, such as computers and robots, rather than with humans. In 1991, Carol Gray developed Social Stories, an intervention tool aimed to increase children’s social skills. Social stories are short scenarios written or tailored for autistic individuals to help them understand and behave appropriately in social situations. This study shows that, in specific situations, the social performance of autistic children improves when using the robot Probo, as a medium for social story telling, than when a human reader tells the stories. The robot tells Social Stories to teach ASD children how to react in situations like saying “hello”, saying “thank you” and “sharing toys”. The robot has the capability of expressing emotions and attention via its facial expressions and its gaze. The paper discusses the use of Probo as an added-value therapeutic tool for social story telling and presents the first experimental results. Keywords: social robot; ASD children; social story; robot assisted therapy

The effect of the owner’s personality on the behaviour of owner-dog dyads
Author(s): Anna Kis, Borbála Turcsán, Ádám Miklósi and Márta Gácsipp.: 373–385 (13)More LessWe describe the relationships between dog owners’ personality attributes (assessed via questionnaire), their behaviours and the dog’s behaviours observed during brief dog-owner and dog-stranger interactions (N = 78). Interactions comprised the owner commanding the dog to sit, and the stranger showing a ball to the restrained dog and then hiding it. Owners scoring higher on neuroticism and openness used more commands (gestural and verbal) when asking the dog to sit, and the dogs of owners higher on neuroticism obeyed with a longer latency and spent more time looking at the stranger. More extraverted owners praised their dog more, and it took longer for their dogs to look at the stranger but they spent more time looking at the stranger, whereas dogs of more agreeable owners spent more time looking at the ball. Based on these results we conclude that some aspects of owners’ personality appear to be tied to their dog’s attentional concerns. Keywords: dog-human interaction; personality; multivariate statistical methods

The owners’ assessment of “everyday dog memory”: A questionnaire study
Author(s): Péter Pongrácz, Veronika Benedek, Sybille Enz and Ádám Miklósipp.: 386–407 (22)More LessIn a questionnaire study we surveyed the owners of 113 companion dogs. Owners had to mark on a four-grade scale how long their dog remembered particular memory items (persons, other animals, events, objects). Additionally we collected descriptive data on the demographical characteristics of the dog and the keeping conditions.A principal component analysis on the memory items resulted in five components. From these, two were connected to people (‘Family’ and ‘Intruders’), three other components contained individual items of memory of objects and events (‘Going out’, Playing’ and ‘Doing something’). Analyses of variance revealed that the dog-owner relationship, the keeping conditions, age and breed of the dog affect the dogs’ memory as described by the owner. The amount of time spent together or the education of the owner had no or minimal effect on these components.Our study showed that owners form stable opinions about their dogs’ episodic memory capacity. Nevertheless, the results can be biased by such factors that affect either the owners’ opinions about their dog-companions, or the dogs’ access to particular stimuli, which can modify the formation of memory traces. In the future, these results can serve as a starting point for empirical testing of family dogs’ memory. Keywords: dogs; dog owners; memory; questionnaire

What is the appropriate speech rate for a communication robot?
Author(s): Michihiro Shimada and Takayuki Kandapp.: 406–433 (28)More LessThis study investigates the influence of a robot’s speech rate. In human communication, slow speech is considered boring, speech at normal speed is perceived as credible, and fast speech is perceived as competent. To seek the appropriate speech rate for robots, we test whether these tendencies are replicated in human-robot interaction by conducting an experiment with four rates of speech: fast, normal, moderately slow, and slow. Our experimental results reveal a rather surprising trend. Participants prefer normal and moderately slow speech to fast speech. A robot that provides normal or moderately slow speech is perceived as competent. We further study how context affects this perception. In a situation where the robot and participants talk while walking, we found that slow speech was the most comprehensible. In addition, slow speech is subjectively perceived as good as moderately slow and normal speech.

Getting interaction theory (IT) together: Integrating developmental, phenomenological, enactive, and dynamical approaches to social interaction
Author(s): Tom Froese and Shaun Gallagherpp.: 436–468 (33)More LessWe argue that progress in our scientific understanding of the ‘social mind’ is hampered by a number of unfounded assumptions. We single out the widely shared assumption that social behavior depends solely on the capacities of an individual agent. In contrast, both developmental and phenomenological studies suggest that the personal-level capacity for detached ‘social cognition’ (conceived as a process of theorizing about and/or simulating another mind) is a secondary achievement that is dependent on more immediate processes of embodied social interaction. We draw on the enactive approach to cognitive science to further clarify this strong notion of ‘social interaction’ in theoretical terms. In addition, we indicate how this interaction theory (IT) could eventually be formalized with the help of a dynamical systems perspective on the interaction process, especially by making use of evolutionary robotics modeling. We conclude that bringing together the methods and insights of developmental, phenomenological, enactive and dynamical approaches to social interaction can provide a promising framework for future research. Keywords: theory of mind; cognitive science; phenomenology; embodied cognition; dynamical systems theory; enactive approach; social cognition; interaction theory; evolutionary robotics

You never get a second chance to make a first impression: The effect of visual complexity on intention to use websites
Author(s): Rik Crutzen, Linda de Kruif and Nanne K. de Vriespp.: 469–477 (9)More LessWebsites (e.g. intervention websites targeting health risk behaviors) can be effective in achieving their goals if they are used. The actual use, however, is often very low. This study aimed to assess the effect of visual complexity on intention to use websites, by using within-subjects manipulations of visual complexity and cognitive load (1097 trials, N = 93). The results indicate that high visual complexity has a negative effect on intention to use websites (F(1, 1095) = 14.81, p < .001), but this is fully mediated through attitude towards the website based on the first impression (F(1, 1094) = 13.41, p < .001). This clearly demonstrates the powerfulness of a first impression before interacting with a website and stresses the need for evidence-based insight into how this first impression is constituted. Keywords: visual complexity; websites; intention to use
