ACCURATELY DIAGNOSING AUTISM SPECTRUM DISORDER AMONG A COMORBID POPULATION

Two of the most common neurodevelopmental disorders, attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), are diagnosed in early childhood. The two disorders share similar impairments across domains, are highly comorbid, and have many overlapping symptoms. Studies have shown that among this comorbid population, children receive an ASD diagnosis a few years after their initial ADHD diagnosis, which leads to many negative consequences, including a delay in treatment. The focus in this study was on the early indicators of ASD that are present prior to the age of 3 years in order to educate others on these symptoms. In an effort to help professions better understand ASD symptoms, a checklist was created using information gathered from internet-based databases as well as published questionnaires with a focus on the symptoms of ADHD, ASD, and comorbid ADHD and ASD. The checklist contains early indicators and impairments found across the domains of language functioning, social functioning, emotional functioning, motor functioning, restrictive and repetitive behaviors, and general behaviors. Future studies would benefit from more extensive research regarding early indicators of the comorbid diagnosis of ASD and ADHD

Groupness in Preverbal Infants: Proof of Concept

Infant sociability is generally conceived in terms of dyadic capacities and behaviors. Recently, quantitative evidence has been published to support arguments that infants achieve a criterion for groupness: the capacity to interact simultaneously with two others. Such studies equate this capacity with alternating dyadic acts to the two other members of an interacting trio. Here we propose a stricter threefold criterion for infant groupness, of which the crux is whether the social behavior of an infant at time B is shown to be influenced by what two or more group-members were previously doing at time A. We test the viability of this conceptualization: (a) through its justification of the novel laboratory procedure of studying infant sociability in infant–peer quartets (rather than trios); and, (b) in an analysis of a pilot study of gaze-behavior recorded in 5-min interactions among two quartets of infants aged 6–9 months. We call this a ‘proof of concept’ because our aim is to show that infants are capable of groupness, when groupness is conceptualized in a supra-dyadic way—not that all infants will manifest it, nor that all conditions will produce it, nor that it is commonplace in infants’ everyday lives. We found that both quartets did achieve the minimum criterion of groupness that we propose: mutual gaze predicting coordinated gaze (where two babies, A and B, are looking at each other, and B is then looked at by C, and sometimes D) more strongly than the reverse. There was a significant absence of ‘parallel mutual gaze,’ where the four babies pair off. We conclude that, under specific conditions, preverbal infants can manifest supra-dyadic groupness. Infants’ capacities to exhibit groupness by 9 months of age, and the paucity of parallel mutual gaze in our data, run counter to the assumption that infant sociability, when in groups, is always generated by a dyadic program. Our conceptualization and demonstration of groupness in 8-month-olds thus opens a host of empirical, theoretical, and practical questions about the sociability and care of young babies.The collection of data was funded through a grant from the British Academy: Is Group-Membership Basic to Infant Mental Health?

Decoding Nonverbal Ability: A Theoretical Model for the Acquisition of Nonverbal Decoding Skill

Nonverbal communication adds multiple layers of meaning to social interaction above that conveyed by words. The comprehension of these nonverbal messages depends on individual ability which varies greatly between individuals. Variation in nonverbal communication ability and the variables of influence that have been associated with it over decades of research are the topic of this research project. Variables that have been correlated to nonverbal communication skill were used to develop a theory for the development of this skill and construct an evidence-based theoretical model that provides an explanation for nonverbal skill acquisition and variability. This model was also analyzed for further implications about related theory and research

Eye quietness and quiet eye in expert and novice golf performance: an electrooculographic analysis

Quiet eye (QE) is the final ocular fixation on the target of an action (e.g., the ball in golf putting). Camerabased eye-tracking studies have consistently found longer QE durations in experts than novices; however, mechanisms underlying QE are not known. To offer a new perspective we examined the feasibility of measuring the QE using electrooculography (EOG) and developed an index to assess ocular activity across time: eye quietness (EQ). Ten expert and ten novice golfers putted 60 balls to a 2.4 m distant hole. Horizontal EOG (2ms resolution) was recorded from two electrodes placed on the outer sides of the eyes. QE duration was measured using a EOG voltage threshold and comprised the sum of the pre-movement and post-movement initiation components. EQ was computed as the standard deviation of the EOG in 0.5 s bins from –4 to +2 s, relative to backswing initiation: lower values indicate less movement of the eyes, hence greater quietness. Finally, we measured club-ball address and swing durations. T-tests showed that total QE did not differ between groups (p = .31); however, experts had marginally shorter pre-movement QE (p = .08) and longer post-movement QE (p < .001) than novices. A group × time ANOVA revealed that experts had less EQ before backswing initiation and greater EQ after backswing initiation (p = .002). QE durations were inversely correlated with EQ from –1.5 to 1 s (rs = –.48 - –.90, ps = .03 - .001). Experts had longer swing durations than novices (p = .01) and, importantly, swing durations correlated positively with post-movement QE (r = .52, p = .02) and negatively with EQ from 0.5 to 1s (r = –.63, p = .003). This study demonstrates the feasibility of measuring ocular activity using EOG and validates EQ as an index of ocular activity. Its findings challenge the dominant perspective on QE and provide new evidence that expert-novice differences in ocular activity may reflect differences in the kinematics of how experts and novices execute skills

Shared Perception in Human-Robot Interaction

Interaction can be seen as a composition of perspectives: the integration of perceptions, intentions, and actions on the environment two or more agents share. For an interaction to be effective, each agent must be prone to “sharedness”: being situated in a common environment, able to read what others express about their perspective, and ready to adjust one’s own perspective accordingly. In this sense, effective interaction is supported by perceiving the environment jointly with others, a capability that in this research is called Shared Perception. Nonetheless, perception is a complex process that brings the observer receiving sensory inputs from the external world and interpreting them based on its own, previous experiences, predictions, and intentions. In addition, social interaction itself contributes to shaping what is perceived: others’ attention, perspective, actions, and internal states may also be incorporated into perception. Thus, Shared perception reflects the observer's ability to integrate these three sources of information: the environment, the self, and other agents. If Shared Perception is essential among humans, it is equally crucial for interaction with robots, which need social and cognitive abilities to interact with humans naturally and successfully. This research deals with Shared Perception within the context of Social Human-Robot Interaction (HRI) and involves an interdisciplinary approach. The two general axes of the thesis are the investigation of human perception while interacting with robots and the modeling of robot’s perception while interacting with humans. Such two directions are outlined through three specific Research Objectives, whose achievements represent the contribution of this work. i) The formulation of a theoretical framework of Shared Perception in HRI valid for interpreting and developing different socio-perceptual mechanisms and abilities. ii) The investigation of Shared Perception in humans focusing on the perceptual mechanism of Context Dependency, and therefore exploring how social interaction affects the use of previous experience in human spatial perception. iii) The implementation of a deep-learning model for Addressee Estimation to foster robots’ socio-perceptual skills through the awareness of others’ behavior, as suggested in the Shared Perception framework. To achieve the first Research Objective, several human socio-perceptual mechanisms are presented and interpreted in a unified account. This exposition parallels mechanisms elicited by interaction with humans and humanoid robots and aims to build a framework valid to investigate human perception in the context of HRI. Based on the thought of D. Davidson and conceived as the integration of information coming from the environment, the self, and other agents, the idea of "triangulation" expresses the critical dynamics of Shared Perception. Also, it is proposed as the functional structure to support the implementation of socio-perceptual skills in robots. This general framework serves as a reference to fulfill the other two Research Objectives, which explore specific aspects of Shared Perception. For what concerns the second Research Objective, the human perceptual mechanism of Context Dependency is investigated, for the first time, within social interaction. Human perception is based on unconscious inference, where sensory inputs integrate with prior information. This phenomenon helps in facing the uncertainty of the external world with predictions built upon previous experience. To investigate the effect of social interaction on such a mechanism, the iCub robot has been used as an experimental tool to create an interactive scenario with a controlled setting. A user study based on psychophysical methods, Bayesian modeling, and a neural network analysis of human results demonstrated that social interaction influenced Context Dependency so that when interacting with a social agent, humans rely less on their internal models and more on external stimuli. Such results are framed in Shared Perception and contribute to revealing the integration dynamics of the three sources of Shared Perception. The others’ presence and social behavior (other agents) affect the balance between sensory inputs (environment) and personal history (self) in favor of the information shared with others, that is, the environment. The third Research Objective consists of tackling the Addressee Estimation problem, i.e., understanding to whom a speaker is talking, to improve the iCub social behavior in multi-party interactions. Addressee Estimation can be considered a Shared Perception ability because it is achieved by using sensory information from the environment, internal representations of the agents’ position, and, more importantly, the understanding of others’ behavior. An architecture for Addressee Estimation is thus designed considering the integration process of Shared Perception (environment, self, other agents) and partially implemented with respect to the third element: the awareness of others’ behavior. To achieve this, a hybrid deep-learning (CNN+LSTM) model is developed to estimate the speaker-robot relative placement of the addressee based on the non-verbal behavior of the speaker. Addressee Estimation abilities based on Shared Perception dynamics are aimed at improving multi-party HRI. Making robots aware of other agents’ behavior towards the environment is the first crucial step for incorporating such information into the robot’s perception and modeling Shared Perception

Investigation of Mirror Image Bias: Evidence For the Use of Psychophysiological Measures as Indicators of Cognitive Heuristics

The Mirror Imaging Bias (MIB) is gaining attention as a prominent quality factor in analysts\u27 performance. MIB is an irrationality in which analysts perceive and process information through the filter of personal experience. As evidenced by notable historical events, the consequences of this bias can be dramatic. A way to understand MIB in humans is sought. How analysts analyze data, are trained, and interact with biases is explored. An experiment testing for the appearance of MIB was designed and completed. Measures from an eye tracker as well as physiological measures were collected. Results show a significant correlation between pupil diameter and the appearance of MIB. There is a significant correlation between response time as well as the number of fixations and the viewpoint of the question. These results support that MIB is used as a shortcut to minimize mental workload in decision making in uncertain situations

Participatory sense-making in psychotherapy

250 p.La presente tesis propone un enfoque enactivo de la psiquiatría y la psicoterapia que va más allá de una concepción puramente ¿mentalista¿ de la empatía y la alianza terapéutica hacia una perspectiva de segunda persona, destacando el papel constitutivo de la interacción corporal pre-reflectiva entre terapeutas y pacientes en el proceso terapéutico. La tesis se cimienta en la teoría de la intersubjetividad entendida como participatory sense-making, que describe la coordinación de actividades intencionales y no intencionales como vehículo de la emergencia de significados compartidos en las interacciones interpersonales. Se presentan tres trabajos aplicando el marco enactivo a la investigación en psicoterapia: (1) un comentario sobre estudios correlacionales de coordinación no verbal y resultado psicoterapéutico, donde se sugieren nuevas hipótesis de trabajo e interpretaciones de datos empíricos, (2) un análisis interpretativo-fenomenológico de los mecanismos intercorporales pre-reflectivos implicados en la transición de la terapia presencial al formato online, y (3) un análisis y clasificación fenomenológico-enactivo de las intervenciones corporales en los procesos terapéuticos. Estos trabajos demuestran que el marco enactivo promueve una forma particular de investigar psicoterapia
