Humanoid Cognitive Robots That Learn by Imitating: Implications for Consciousness Studies.
2018
While the concept of a conscious machine is intriguing, producing such a machine remains controversial and challenging. Here we describe how our work on creating a humanoid cognitive robot that learns to perform tasks via imitation learning relates to this issue. Our discussion is divided into three parts. First, we summarize our previously-detailed framework for advancing the understanding of the nature of phenomenal consciousness. This framework is based on identifying computational correlates of consciousness. Second, we describe a cognitive robotic system that we recently developed that learns to perform tasks by imitating human-provided demonstrations. This humanoid robot uses cause-ef…
Immersion revisited:A review of existing definitions of immersion and their relation to different theories of presence
2016
The term immersion continues to be applied inconsistently within and across different fields of research connected with the study of virtual reality and interactive media. Moreover, immersion is oftentimes used interchangeably with the terms presence and engagement. This article details a review of existing definitions of immersion originating within the study of video games, virtual environments, and literary works of fiction. Based on this review, a three-dimensional taxonomy of the various conceptualizations of immersion is proposed. That is, the existing definitions of immersion may be broadly divided into three categories, each representing a dimension of the taxonomy: immersion as a p…
Bone-Healing Pattern on the Surface of Titanium Implants at Cortical and Marrow Compartments in Two Topographic Sites: an Experimental Study in Rabbi…
2018
This study evaluates the bone-healing patterns on the surface of titanium implants at the cortical and marrow compartments of bicortically-installed implants in the diaphysis and metaphysis of rabbit tibiae. In 27 New Zealand rabbits, two implants, one for each macro-design and with equal resorbable blasted media (RBM) implant surfaces, were randomly implanted in the diaphysis or metaphysis of each tibia. The flaps were sutured to allow submerged healing. The animals were sacrificed after two, four, or eight weeks, with nine weeks used for the period of healing. Ground sections were prepared and analyzed. No statistically significant differences were found between the two groups for newly f…
Check in, check out! : käyttäytymisen tehostettua tukea lähikoulussa
2018
Finnish schools struggle with problem behaviour and need new interventions which are effective, acceptable, and can be implemented with high fidelity in general classrooms. The aim of this study was to examine the effects of Check in check out (CICO) support in decreasing the disruptive behaviours of general education primary school pupils. CICO can be regarded as an intensified level of support in Finnish schools, and its key features are brief morning and afternoon meetings with a CICO coach, the use of a Daily Report Card (DRC), regular positive feedback during the day by the classroom teacher, and parental involvement. The specific aims of the study were threefold: first, to pilot the i…
Statements About the Pervasiveness of Behavior Require Data About the Pervasiveness of Behavior
2020
Despite recent close attention to issues related to the reliability of psychological research (e.g., the replication crisis), issues of the validity of this research have not been considered to the same extent. This paper highlights an issue that calls into question the validity of the common research practice of studying samples of individuals, and using sample-based statistics to infer generalizations that are applied not only to the parent population, but to individuals. The lack of ergodicity in human data means that such generalizations are not justified. This problem is illustrated with respect to two common scenarios in psychological research that raise questions for the sorts of the…
Sentience and the Origins of Consciousness: From Cartesian Duality to Markovian Monism
2020
This essay addresses Cartesian duality and how its implicit dialectic might be repaired using physics and information theory. Our agenda is to describe a key distinction in the physical sciences that may provide a foundation for the distinction between mind and matter, and between sentient and intentional systems. From this perspective, it becomes tenable to talk about the physics of sentience and &lsquo

La emergencia viral como consecuencia de la interacción entre las variabilidades genéticas del virus y huésped
2015
La variabilidad genética en las poblaciones de huéspedes para la susceptibilidad al patógeno es esencial para la propagación de un virus emergente. Los modelos matemáticos predicen que la tasa de difusión del patógeno se frena a medida que aumenta la frecuencia y la diversidad de alelos de resistencia en la población huésped148,230. Sin embargo, las pruebas experimentales de esta hipótesis son escasas. Por ese motivo, este trabajo aborda la cuestión de cuánta heterogeneidad genética del huésped es necesaria para el cambio del destino evolutivo del virus. El modelo de patosistema experimental utilizado en este trabajo está compuesto por el Virus del grabado del tabaco (TEV), aislado At17b (T…
Action-Depicting Gestures and Morphosyntax: The Function of Gesture-Speech Alignment in the Conversational Turn
2021
The current study examines the role of action-depicting gestures in conversational turns by focusing on their semantic characteristics and temporal position in relation to their verbal affiliates (action verbs or more complex verb phrases). The data are video recordings of naturally occurring interactions in multilingual construction sites in Norway. The analysis distinguishes two modes of action depiction: generic depictions, which represent the action as a general type, and contextualized depictions, which in addition include deictic references to the spatio-material environment or iconic representations of the specific manner of action performance. These two modes typically occupy differ…
