(2019): The benefits of and barriers to using a social robot PARO in care settings: a scoping review. In: BMC geriatrics 19 (1). DOI: 10.1186/s12877-019-1244-6
DOI: http://www.ncbi.nlm.nih.gov/pubmed/31443636 Abstract: BACKGROUND Given the complexity of providing dementia care in hospitals, integrating technology into practice is a high challenge and an important opportunity. Although there are a growing demand and interest in using social robots in a variety of care settings to support dementia care, little is known about the impacts of the robotics and their application in care settings, i.e., what worked, in which situations, and how. METHODS Scientific databases and Google Scholar were searched to identify publications published since 2000. The inclusion criteria consisted of older people with dementia, care setting, and social robot PARO. RESULTS A total of 29 papers were included in the review. Content analysis identified 3 key benefits of and 3 barriers to the use of PARO. Main benefits include: reducing negative emotion and behavioral symptoms, improving social engagement, and promoting positive mood and quality of care experience. Key barriers are: cost and workload, infection concerns, and stigma and ethical issues. This review reveals 3 research gaps: (a) the users' needs and experiences remain unexplored, (b) few studies investigate the process of how to use the robot effectively to meet clinical needs, and (c) theory should be used to guide implementation. CONCLUSIONS Most interventions conducted have been primarily researcher-focused. Future research should pay more attention to the clinical needs of the patient population and develop strategies to overcome barriers to the adoption of PARO in order to maximize patient benefits.

(2018) : Adapting Robot Behavior using Regulatory Focus Theory, User Physiological State and Task-Performance Information: 2018 27th IEEE International Symposium on Robot and Human Interactive Communication (RO-MAN): Nanjing, China: IEEE Robotics & Automation Society, S. 644-651
DOI: https://doi.org/10.1109/ROMAN.2018.8525648 Abstract: Social robots are expected to be part of everyday life of people. This will generate interactions between humans and robots that may have positive or negative effects on the users. In order to minimize the negative effects and increase robot persuasiveness, robots should behave in an appropriate manner by adapting to their users. How to achieve this adaptation remains a challenge. We propose the usage of the Regulatory Focus Theory, user physiological state, and game-performance information in order to detect user stress and adapt the behavior of the robot. We present a longitudinal experiment conducted with 35 participants in a game-like scenario. The robot was trained for adapting to the regulatory focus of the users and decreasing their stress while they were playing the game. For this reason, we trained the robot with 12 participants with Chronic Promotion State and with 12 participants with Chronic Prevention State. We used a Q-Learning algorithm based on the Regulatory Focus of the participants, user stress, and task performance. The model obtained was tested with 2 groups (6 and 5 participants, respectively) according to their Chronic Regulatory Focus. Results show that our system was able to generate a robot behavior capable of increasing robot persuasiveness and reducing user stress, which is of great importance for social robots.

(2017): As You Sow, So Shall You Reap. Gender-Role Attitudes and Late-Life Cognition. In: Psychological science 28 (9), S. 1201-1213. DOI: 10.1177/0956797617708634
DOI: http://www.ncbi.nlm.nih.gov/pubmed/28737096 Abstract: Some studies have found that women outperform men in episodic memory after midlife. But is this finding universal, and what are the reasons? Gender differences in cognition are the result of biopsychosocial interactions throughout the life course. Social-cognitive theory of gender development posits that gender roles may play an important mediating role in these interactions. We analyzed country differences in the gender differential in cognition after midlife using data from individuals age 50 and above ( N = 226,661) from 27 countries. As expected, older women performed relatively better in countries characterized by more equal gender-role attitudes. This result was robust to cohort differences as well as reverse causality. The effect was partially mediated by education and labor-force participation. Cognition in later life thus cannot be fully understood without reference to the opportunity structures that sociocultural environments do (or do not) provide. Global population aging raises the importance of understanding that gender roles affect old-age cognition and productivity. zitiert von 3

(2017): Efficacy of an individualized social competence training for children with Oppositional Defiant Disorders/Conduct Disorders. In: Psychotherapy research : journal of the Society for Psychotherapy Research 27 (3), S. 326-337. DOI: 10.1080/10503307.2015.1094587
DOI: http://www.ncbi.nlm.nih.gov/pubmed/26522864 Abstract: OBJECTIVES Group-based Cognitive-Behavioral Therapy of children with aggressive behavior has resulted in significant reductions of behavior problems with small to medium effect sizes. We report the efficacy of an individualized Treatment Program for Children with Aggressive Behavior. METHOD A within-subject design with two phases (waiting, treatment) was chosen. Sixty boys aged 6-12 years with peer-related aggressive behavior were included. The course of the outcome measures (growth rates) during a 6-week waiting phase was compared with those in the subsequent treatment phase (24 weekly child sessions together with an average of 8 parent contacts) by multilevel modeling. Primary outcome was peer-related aggressive behavior rated by parents. Further outcome measures included parent ratings and patient self-reports of aggressive and prosocial behavior. RESULTS During the treatment, growth rates for all parent-rated outcome measures were significant (p < .001) and comparison with the waiting phase indicated a stronger decrease in aggressive behavior and a stronger increase in prosocial behavior. For all self-rated outcome measures, growth rates during the treatment were significant (p < .01), but comparison with the waiting phase indicated a stronger decrease only for disturbance of social interaction. CONCLUSIONS The treatment program is an effective intervention for children with peer-related aggressive behavior.

(2017): Antioxidant allocation modulates sperm quality across changing social environments. In: PLoS one 12 (5). DOI: 10.1371/journal.pone.0176385
DOI: http://www.ncbi.nlm.nih.gov/pubmed/28472052 Abstract: In promiscuous species, male reproductive success depends on their ability to mate with fertile females and on the fertilizing ability of their sperm. In such species, theory predicts that, owing to a trade-off between pre- and post-copulatory reproductive traits, males with lesser access to females should increase resource investment into those sperm traits that enhance fertilization success-usually referred to as ejaculate quality. This prediction has been validated in several taxa, yet studies on the physiological mechanisms modulating ejaculate quality are lacking. Sperm cells are highly vulnerable to oxidative stress, which impairs male fertility. Therefore, males that better protect their sperm from oxidative stress are expected to achieve higher ejaculate quality. Based on theoretical expectations, and since social dominance is a major determinant of mating opportunity, we predicted that subordinate males should invest more into the antioxidant protection of their sperm in order to achieve higher ejaculate quality. We maintained 60 male and 60 female wild-caught house sparrows Passer domesticus in outdoor aviaries, where we experimentally manipulated male social status to test our predictions. We measured cellular oxidative stress and enzymatic antioxidant activity in blood and sperm both before and after manipulating social ranks. Before manipulating the social status, we found that ejaculate viability correlated with oxidative stress level in sperm, with dominant males producing more oxidized and less viable ejaculates. Further, males at the lower end of the hierarchy produced ejaculates of similar quality to those of dominant males, suggesting that restricted access to resources might limit male reproductive strategies. After experimentally manipulating the social status, males matched their ejaculate quality to their new rank, while increases in antioxidant investment into ejaculates paralleled increases in ejaculate viability. Oxidative stress has been proposed as a general constraint to the evolution of life histories. Our results highlight oxidative stress and strategic antioxidant allocation as important proximate physiological mechanisms underlying male reproductive strategies.

(2016): A survey of autonomous human affect detection methods for social robots engaged in natural HRI. In: Journal of Intelligent & Robotic Systems 82 (1), S. 101-133. DOI: 10.1007/s10846-015-0259-2
DOI: https://doi.org/10.1007/s10846-015-0259-2 Abstract: In Human-Robot Interactions (HRI), robots should be socially intelligent. They should be able to respond appropriately to human affective and social cues in order to effectively engage in bi-directional communications. Social intelligence would allow a robot to relate to, understand, and interact and share information with people in real-world human-centered environments. This survey paper presents an encompassing review of existing automated affect recognition and classification systems for social robots engaged in various HRI settings. Human-affect detection from facial expressions, body language, voice, and physiological signals are investigated, as well as from a combination of the aforementioned modes. The automated systems are described by their corresponding robotic and HRI applications, the sensors they employ, and the feature detection techniques and affect classification strategies utilized. This paper also discusses pertinent future research directions for promoting the development of socially intelligent robots capable of recognizing, classifying and responding to human affective states during real-time HRI.

(2014): The role of age and motivation for the experience of social acceptance and rejection. In: Developmental Psychology 50 (7), S. 1943-1950. DOI: 10.1037/a0036979
DOI: http://www.ncbi.nlm.nih.gov/pubmed/24842461 Abstract: A study with n = 55 younger (18-33 years, M = 23.67) and n = 58 older (61-85 years, M = 71.44) adults investigated age-related differences in social approach and avoidance motivation and their consequences for the experience of social interactions. Results confirmed the hypothesis that a predominant habitual approach motivation in younger adults shifts toward a stronger avoidance motivation in older adults. Moreover, age and momentary motivation predicted the experience of an actual social interaction. Younger adults reported stronger negative emotions in a rejection situation when striving to approach acceptance rather than avoid rejection. Conversely, older adults reported fewer positive emotions in a rejection situation when they attempted to avoid rejection rather than approach acceptance. Taken together, the present study demonstrates that the same motivation has different consequences for the experience of potentially threatening social situations in younger and older adults. People seem to react emotionally when the achievement of important developmental goals (approaching others in young adulthood, avoiding negative social interactions in older adulthood) is thwarted. Moreover, results suggest that approach and avoidance motivation play an important role for socioemotional development.

(2013): Being and feeling in sync with an adaptive virtual partner. Brain mechanisms underlying dynamic cooperativity. In: Cerebral cortex (New York, N.Y. : 1991) 23 (11), S. 2592-2600. DOI: 10.1093/cercor/bhs243
DOI: http://www.ncbi.nlm.nih.gov/pubmed/22892422 Abstract: Cooperation is intrinsic to the human ability to work together toward common goals, and depends on sensing and reacting to dynamically changing relationships between coacting partners. Using functional magnetic resonance imaging (fMRI) and a paradigm in which an adaptive pacing signal simulates a virtual partner, we examined the neural substrates underlying dynamic joint action. A single parameter controlled the degree to which the virtual partner adapted its behavior in relation to participant taps, thus simulating varying degrees of cooperativity. Analyses of fMRI data using objective and subjective measures of synchronization quality found the relative balance of activity in two distinct neural networks to depend on the degree of the virtual partner's adaptivity. At lower degrees of adaptivity, when the virtual partner was easier to synchronize with, cortical midline structures were activated in conjunction with premotor areas, suggesting a link between the action and socio-affective components of cooperation. By contrast, right lateral prefrontal areas associated with central executive control processes were recruited during more cognitively challenging interactions while synchronizing with an overly adaptive virtual partner. Together, the reduced adaptive sensorimotor synchronization paradigm and pattern of results illuminate neural mechanisms that may underlie the socio-emotional consequences of different degrees of entrainment success.

(2013) : Bio-inspired solutions for intelligent android perception and control: 2013 IEEE International Symposium on Technology and Society (ISTAS): Social Implications of Wearable Computing and Augmediated Reality in Everyday Life: Toronto, Canada: IEEE
DOI: https://doi.org/10.1109/ISTAS.2013.6613096 Abstract: Summary form only given. After more than half of century of manufacturing-oriented robotics, robots are now evolving and expanding into new applications involving a human-style interaction with people in unstructured environments. Such an endeavour requires a different set of skills for the new generation of robots, which are expected to exhibit an increased ability to intelligently connect perception to action. Due to their expected omnipresence in the lives of people, the new-generation robots should be sensitive to the attitudes and expectations of normal people. They should be endowed with more efficient interaction capabilities allowing for a higher degree of flexibility and autonomy in order to make appropriate decisions in routine and emergency situations. In order to naturally blend within human society, the new-generation robots should not only look as humans, but should also behave as much as possible as humans. They are in a way expected to be, as initially imagined by Capek in his R.U.R. Rossum’s Universal Robots play, anthropomorphic artefacts, androids, enabled to think on their own and governed by Asimov’s laws of robotics hardwired into every robot’s positronic brain. While for a long time, engineers have built upon mathematics, physics and chemistry in order to develop an ever growing variety of industrial artefacts and machines, this approach cannot anymore rise to the challenge of designing these androids. The time has now arrived to add biology and more specifically, human anatomy, physiology and psychology to the scientific sources of knowledge to develop a new, bio-inspired, generation of intelligent androids. Advocating this emergent trend, this presentation will discuss a number of relevant issues such as bioinspired robot sensors and neural networks, humanrobot interaction techniques for symbiotic partnership, as well as moral, ethical, theological, legal, and social challenges in a soon-to-be cyborgsociety world.

(2012): Interplay of oxytocin, vasopressin, and sex hormones in the regulation of social recognition. In: Behavioral neuroscience 126 (1), S. 97-109. DOI: 10.1037/a0026464
DOI: http://www.ncbi.nlm.nih.gov/pubmed/22141469 Abstract: Social Recognition is a fundamental skill that forms the basis of behaviors essential to the proper functioning of pair or group living in most social species. We review here various neurobiological and genetic studies that point to an interplay of oxytocin (OT), arginine-vasopressin (AVP), and the gonadal hormones, estrogens and testosterone, in the mediation of social recognition. Results of a number of studies have shown that OT and its actions at the medial amygdala seem to be essential for social recognition in both sexes. Estrogens facilitate social recognition, possibly by regulating OT production in the hypothalamus and the OT receptors at the medial amygdala. Estrogens also affect social recognition on a rapid time scale, likely through nongenomic actions. The mechanisms of these rapid effects are currently unknown but available evidence points at the hippocampus as the possible site of action. Male rodents seem to be more dependent on AVP acting at the level of the lateral septum for social recognition than female rodents. Results of various studies suggest that testosterone and its metabolites (including estradiol) influence social recognition in males primarily through the AVP V1a receptor. Overall, it appears that gonadal hormone modulation of OT and AVP regulates and fine tunes social recognition and those behaviors that depend upon it (e.g., social bonds, social hierarchies) in a sex specific manner. This points at an important role for these neuroendocrine systems in the regulation of the sex differences that are evident in social behavior and of sociality as a whole.

(2012) : Captain may I? Proxemics study examining factors that influence distance between humanoid robots, children, and adults, during human-robot interaction: 2012 7th ACM/IEEE International Conference on Human-Robot Interaction (HRI): Boston, MA: IEEE, S. 203-204
Abstract: This proxemics study examines whether the physical distance between robots and humans differ based on the following factors: 1) age: children vs. adults, 2) who initiates the approach: humans approaching the robot vs. robot approaching humans, 3) prompting: verbal invitation vs. non-verbal gesture (e.g., beckoning), and 4) informing: announcement vs. permission vs. nothing. Results showed that both verbal and non-verbal prompting had significant influence on physical distance. Physiological data is also used to detect the appropriate timing of approach for a more natural and comfortable interaction.

(2010): Emotion processing and the amygdala: from a 'low road' to 'many roads' of evaluating biological significance. In: Nature reviews. Neuroscience 11 (11), S. 773-783. DOI: 10.1038/nrn2920
DOI: https://doi.org/10.1038/nrn2920 Abstract: A subcortical pathway through the superior colliculus and pulvinar to the amygdala is commonly assumed to mediate the non-conscious processing of affective visual stimuli. We review anatomical and physiological data that argue against the notion that such a pathway plays a prominent part in processing affective visual stimuli in humans. Instead, we propose that the primary role of the amygdala in visual processing, like that of the pulvinar, is to coordinate the function of cortical networks during evaluation of the biological significance of affective visual stimuli. Under this revised framework, the cortex has a more important role in emotion processing than is traditionally assumed.

(2007): Language as context for the perception of emotion. In: Trends in cognitive sciences 11 (8), S. 327-332. DOI: 10.1016/j.tics.2007.06.003
DOI: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2225544 Abstract: In the blink of an eye, people can easily see emotion in another person's face. This fact leads many to assume that emotion perception is given and proceeds independently of conceptual processes such as language. In this paper we suggest otherwise and offer the hypothesis that language functions as a context in emotion perception. We review a variety of evidence consistent with the language-as-context view and then discuss how a linguistically relative approach to emotion perception allows for intriguing and generative questions about the extent to which language shapes the sensory processing involved in seeing emotion in another person's face.

(2006): Towards the neurobiology of emotional body language. In: Nature reviews. Neuroscience 7 (3), S. 242-249. DOI: 10.1038/nrn1872
DOI: http://www.ncbi.nlm.nih.gov/pubmed/16495945 Abstract: People's faces show fear in many different circumstances. However, when people are terrified, as well as showing emotion, they run for cover. When we see a bodily expression of emotion, we immediately know what specific action is associated with a particular emotion, leaving little need for interpretation of the signal, as is the case for facial expressions. Research on emotional body language is rapidly emerging as a new field in cognitive and affective neuroscience. This article reviews how whole-body signals are automatically perceived and understood, and their role in emotional communication and decision-making.
