How to build a supervised autonomous system for robot-enhanced therapy for children with autism spectrum disorder
Robot-Assisted Therapy (RAT) has successfully been used to improve social skills in children with autism spectrum disorders (ASD) through remote control of the robot in so-called Wizard of Oz (WoZ) paradigms.However, there is a need to increase the autonomy of the robot both to lighten the burden on human therapists (who have to remain in control and, importantly, supervise the robot) and to provide a consistent therapeutic experience. This paper seeks to provide insight into increasing the autonomy level of social robots in therapy to move beyond WoZ. With the final aim of improved human-human social interaction for the children, this multidisciplinary research seeks to facilitate the use of social robots as tools in clinical situations by addressing the challenge of increasing robot autonomy.We introduce the clinical framework in which the developments are tested, alongside initial data obtained from patients in a first phase of the project using a WoZ set-up mimicking the targeted supervised-autonomy behaviour. We further describe the implemented system architecture capable of providing the robot with supervised autonomy
Abstractions in Judgment: Does Construal Level Influence the System Specific Reasoning of Dual Process Theory?
Recent research have proposed a link between two large theoretical bodies, namely the Construal Level Theory (CLT) and the Dual Process Theory (DPT). The proposed connection is that DPT systems share characteristics with CLT constructs; that systems operate at different levels of abstraction. While these claims have been made, there has been no direct attempt to scrutinize the implication. The hypothesis that a link between these theories exists is examined empirically in this paper. We investigate whether people respond in a DPT system specific way when primed with different levels of construal. 89 high school students were primed with different levels of construal and performed binary choice judgments of either easy or hard difficulty. We expected that the percent of correct judgments that participants made while primed with a lowlevel construal would be higher than participants primed with a high-level construal, in the easy condition. Conversely, we expected that the percent of correct judgments that participants made while primed with a high-level construal would be higher than participants primed with a low-level construal, in the hard condition. The results indicate that there is no such connection. We discuss whether this result is due to diminishing priming and/or a failure to replicate other studies
Semantic analysis suggest Dark Past and Bright Future
Based on the findings of the Ingroup Allocation Model (IAM), which suggests that people use evaluative communication to form and maintain groups and as a result increase the individuals’ inclusive fitness, we present the Dark Past & Bright Future (DPBF) hypothesis. This framework suggests that people use positive evaluative statements to induce behaviors that are consistent with the speakers’ goals. Negative evaluative statements, on the other hand, suggest correction of previous mistakes so that positive results can be obtained in the future. DPBF is compared to Construal Level Theory (CLT) which suggests that values diminish over time and favors symmetrical valence distributions. Data from text analysis suggest that DPBF’s distribution is favored over CLT’s
Engagement: A traceable motivational concept in human-robot interaction
Engagement is essential to meaningful social interaction between humans. Understanding the mechanisms by which we detect engagement of other humans can help us understand how we can build robots that interact socially with humans. However, there is currently a lack of measurable engagement constructs on which to build an artificial system that can reliably support social interaction between humans and robots. This paper proposes a definition, based on motivation theories, and outlines a framework to explore the idea that engagement can be seen as specific behaviors and their attached magnitude or intensity. This is done by the use of data from multiple sources such as observer ratings, kinematic data, audio and outcomes of interactions. We use the domain of human-robot interaction in order to illustrate the application of this approach. The framework further suggests a method to gather and aggregate this data. If certain behaviors and their attached intensities co-occur with various levels of judged engagement, then engagement could be assessed by this framework consequently making it accessible to a robotic platform. This framework could improve the social capabilities of interactive agents by adding the ability to notice when and why an agent becomes disengaged, thereby providing the interactive agent with an ability to reengage him or her. We illustrate and propose validation of our framework with an example from robot-assisted therapy for children with autism spectrum disorder. The framework also represents a general approach that can be applied to other social interactive settings between humans and robots, such as interactions with elderly people
Incidental processing of biological motion: : Effects of orientation, local-motion and global-form features
Previous studies on biological motion perception indicate that the processing of biological motion is fast and automatic. A segment of these studies has shown that task irrelevant and to-be-ignored biological figures are incidentally processed since they interfere with the main task. However more evidence is needed to understand the role of local-motion and global-form processing mechanisms in incidentally processed biological figures. This study investigates the effects of local-motion and global-form features on incidental processing. Point light walkers (PLW) were used in a flanker paradigm in a direction discrimination task to assess the influence of the flankers. Our results show that upright oriented PLW flankers with global-form features have more influence on visual processing of the central PLW than inverted or scrambled PLW flankers with only local-motion features
The Promotion of a Bright Future and the Prevention of a Dark Future: Time Anchored Incitements in News Articles and Facebook’s Status Updates
Background: Research suggests that humans have the tendency to increase the valence of events when these are imagined to happen in the future, but to decrease the valence when the same events are imagined to happen in the past. This line of research, however, has mostly been conducted by asking participants to value imagined, yet probable, events. Our aim was to re-examine this time-valence asymmetry using real-life data: a Reuter’s news and a Facebook status updates corpus.Method: We organized the Reuter news (120,000,000 words) and the Facebook status updates data (41,056,346 words) into contexts grouped in chronological order (i.e., past, present, and future) using verbs and years as time markers. These contexts were used to estimate the valence of each article and status update, respectively, in relation to the time markers using natural language processing tools (i.e., the Latent Semantic Analysis algorithm).Results: Our results using verbs, in both text corpus, showed that valence for the future was significantly higher compared to the past (future > past). Similarly, in the Reuter year condition, valence increased approximately linear from 1994 to 1999 for texts written 1996–1997. In the Facebook year condition, the valence of the future was also significantly higher than past valence.Conclusion: Generally, the analyses of the Reuters data indicated that the past is devaluated relative to both the present and the future, while the analyses of the Facebook data indicated that both the past and the present are devaluated against the future. On this basis, we suggest that people strive to communicate the promotion of a bright future and the prevention of a dark future, which in turn leads to a temporal-valence asymmetrical phenomenon (valence = past < present < future).

Tracking the origin of metasomatic and ore-forming fluids in IOCG deposits through apatite geochemistry (Nautanen North deposit, Norrbotten, Sweden)
International audienceThe relative contribution of magmatic and non-magmatic fluids to the metasomatic and ore-forming processes in iron-oxide copper‑gold (IOCG) deposits is still widely debated. In this study, the petrography, detailed composition and Usbnd Pb ages of various apatite occurrences from the Nautanen North IOCG deposit, Norrbotten, Sweden, were determined to decipher the evolution of fluid sources in the area. The hydrothermal apatite grains grow over muscovite, intergrow with magnetite, amphibole, K-feldspar, chalcopyrite and sericite, and are replaced by epidote, allanite and/or chlorite along the grain margins. Irregular patterns of the apatite grains were revealed by cathodoluminescence imaging. Fluorine in all apatite occurrences is the dominant halogen (1.62-3.58 wt%), chlorine is depleted (up to 0.34 wt%), while bromine and iodine are found in traces (0.7-72 ppm and 0.15-4.2 ppm respectively). The δ37Cl value of the apatite grains ranges between -0.8 and 3.4‰. Uranium-Pb data yield ages between 1.63 and 1.55 Ga (with one exception at 1.49 Ga showing large age errors). Textural evidences show that the apatite grains have been precipitated during the potassic alteration of the D2 event (1.81-1.78 Ga), which is considered a regional, IOCG-related, high-temperature event. Cathodoluminescence textures reveal that all the apatite occurrences have been chemically modified by the late-stage metasomatic and ore-forming fluids during the nucleation of epidote ± allanite ± chlorite. The Br/I and δ37Cl values of the apatite grains can be considered representative of the associated fluid values and show a trend between two end-members, which indicates the contribution and progressive mixing of two different fluids during late-stage ore-related hydrothermal circulation. The ore-forming fluids were mainly issued from exsolved magmatic fluids from S-type bodies, as revealed by the strong affinity of the Br/I ratio of the ore zone with the pegmatite-related apatite. The other end-member associated with the apatite occurrences that co-exist with metasomatic assemblages, is consistent with fluids linked to evaporite dissolution. Apatite dating is interpreted to reflect resetting ages
