(2017) : Acquiring social interaction behaviours for telepresence robots via deep learning from demonstration: 2017 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS): Vancouver, British Columbia, Canada: IEEE, S. 37-42
DOI: https://doi.org/10.1109/IROS.2017.8202135 Abstract: As robots begin to inhabit public and social spaces, it is increasingly important to ensure that they behave in a socially appropriate way. However, manually coding social behaviours is prohibitively difficult since social norms are hard to quantify. Therefore, learning from demonstration (LfD), wherein control policies are inferred from demonstrations of correct behaviour, is a powerful tool for helping robots acquire social intelligence. In this paper, we propose a deep learning approach to learning social behaviours from demonstration. We apply this method to two challenging social tasks for a semi-autonomous telepresence robot. Our results show that our approach outperforms gradient boosting regression and performs well against a hard-coded controller. Furthermore, ablation experiments confirm that each element of our method is essential to its success.

(2014): Executive function is associated with social competence in preschool-aged children born preterm or full term. In: Early human development 90 (6), S. 299-306. DOI: 10.1016/j.earlhumdev.2014.02.011
DOI: https://doi.org/10.1016/j.earlhumdev.2014.02.011 Abstract: BACKGROUND Executive function (EF), defined as higher-order cognitive processes used in planning and organizing actions and emotions, is often impaired in children born preterm. Few studies have assessed social competence, the processes and resources required to meet social demands and achieve social goals, in children born preterm. The relations between EF and social competence in preterm and full term preschoolers have not been well characterized. AIMS To characterize social competence and assess the relationship between EF and social competence in preschool-aged children born preterm or full term. STUDY DESIGN Cross-sectional study. SUBJECTS Study subjects had a history of preterm birth (≤34weeks of gestation) and birth weight <2500g (n=70). Controls were born full term (≥37weeks) (n=79). OUTCOME MEASURES Children completed a battery of EF tasks; a mean age-adjusted z-score for the battery was generated for each child. Parents rated child EF on one scale and child social competence on two standardized scales. RESULTS Compared to full term children, preterm children showed a lower mean EF battery z-score, poorer parent-rated EF, and poorer scores on the two social competence scales. In hierarchical multiple regression models, EF battery z-score and parent-rated EF made independent contributions to both measures of social competence. Preterm birth explained additional variance for one measure of social competence. CONCLUSIONS Standard assessment of EF skills and social competence in young preschool children, including children born preterm, may identify at-risk children for long-term social difficulties and may also provide targets for intervention.

(2011): Executive function mechanisms of theory of mind. In: JOURNAL OF AUTISM AND DEVELOPMENTAL DISORDERS 41 (5), S. 667-678. DOI: 10.1007/s10803-010-1087-7
DOI: http://www.ncbi.nlm.nih.gov/pubmed/20811770 Abstract: This study examined the relationship between Executive Function (EF) and Theory of Mind (ToM) using the Delis-Kaplan Executive Function System (D-KEFS) and three tests of ToM (Reading the Mind in the Eyes test (RMET), Strange Stories test, and Faux Pas test). Separate regression analyses were conducted, and EF predictors varied by ToM test. No EF domains accounted for significant variance in RMET scores; only estimated IQ scores were significant predictors of RMET performance. Verbal fluency and deductive reasoning were significant predictors of performance on the Strange Stories test, while verbal fluency, problem solving, and gender accounted for a significant variance in the Faux Pas test. Results suggest that the ToM tests each utilized differing cognitive mechanisms.

(2010): Compassionate liberals and polite conservatives. Associations of agreeableness with political ideology and moral values. In: Personality & social psychology bulletin 36 (5), S. 655-664. DOI: 10.1177/0146167210366854
DOI: http://www.ncbi.nlm.nih.gov/pubmed/20371797 Abstract: Political conservatism has been characterized by resistance to change and acceptance of inequality, with liberalism characterized by the polar opposite of these values. Political attitudes are heritable and may be influenced by basic personality traits. In previous research, conservatism (vs. liberalism) has been associated positively with Conscientiousness and negatively with Openness-Intellect, consistent with the association of conservatism with resistance to change. Less clear, however, are the personality traits relating to egalitarianism. In two studies, using a personality model that divides each of the Big Five into two aspects, the present research found that one aspect of Agreeableness (Compassion) was associated with liberalism and egalitarianism, whereas the other (Politeness) was associated with conservatism and traditionalism. In addition, conservatism and moral traditionalism were positively associated with the Orderliness aspect of Conscientiousness and negatively with Openness-Intellect. These findings contribute to a more nuanced understanding of personality's relation to political attitudes and values.
