Research Challenge

An important research challenge in Human Machine Systems (HMS) is to create machines that are able to better understand human behavior so that the overall efficiency of the HMS can be enhanced through increased productivity and reduced safety risk. The research question posed in this paper is the following: Can an understanding of physiological behavior of humans be combined with statistical machine learning theory to develop predictive models that are able to accurately predict the cognitive difficulty experienced by humans? In this paper, we answer this question in the affirmative by demonstrating the use of two physiological measurements, pupil dilation and eye-gaze patterns, as indices of cognitive workload. Specifically, we demonstrate the possibility of cognitive context detection through machine learning and classification using eye-tracking data from NRL’s Supervisory Control Operations User Testbed (SCOUTTM), a flexible simulation environment that represents the tasks that a future UAS operator would engage in, while controlling multiple UAS.

Perceptual notation in the Russian folk fairy-talePerceptual notation captures information received from different sense organs but predicated by the same consciousness of “a perceived human being”. In the cognitive context semantics of sensory nominations reflects elements of the perceptual concept. The fact that the verbalization of its facultative elements depends not only on the type of discourse folklore, genre a tale, but also on its subtype a fairy-tale is claimed to be a hypothesis of this research. It settles that in the Russian folk fairy-tale the semantics of perceptual notation is predicated by the opposition “real — irreal world” and the semantics element “fabulous, belonging to the other world” is a basis of the semantic content of the perceptual notation. Besides that, the perceptual semantics in this type of fairy tales correlates with the aesthetical, axiological views of the folklore community on nature and human beings, reconstructing the folk ideal or ant-ideal. Перцептивне означення у російській народній чарівнiй казціПерцептивне означення фіксує інформацію, що надходить від різних органів чуттів, але обумовлену єдиною свідомістю «людини сприймаючої». У когнітивному плані семантика номінацій сенсорики відображає ознаки перцептивного концепту. Те, що вербалізація його факультативних ознак залежить не тільки від типу дискурсу фольклор, жанру казка, але і від підвиду жанру чарівна казка, становить гіпотезу даного дослідження. Встановлюєть­ся що в російській народній чарівній казці семантика перцептивної номінації обумовлена опозицією «реальний- ірреальний світ» і семантична ознака ‘чудовий, що належить іншому світу’ є основою змісту перцептивного означення. Крім того, в даній групі казок перцептивна семантика співвідноситься з естетичними, аксіологічними поглядами фольклорного соціуму на природу і людину, реконструюючи народний ідеал або антиідеал.

Social Learning Processes

The complexity of Stone Age tool-making is assumed to have relied upon cultural transmission, but direct evidence is lacking. This paper reviews evidence bearing on this question provided through five related empirical perspectives. Controlled experimental studies offer special power in identifying and dissecting social learning into its diverse component forms, such as imitation and emulation. The first approach focuses on experimental studies that have discriminated social learning processes in nut-cracking by chimpanzees. Second come experiments that have identified and dissected the processes of cultural transmission involved in a variety of other force-based forms of chimpanzee tool use. A third perspective is provided by field studies that have revealed a range of forms of forceful, targeted tool use by chimpanzees, that set percussion in its broader cognitive context. Fourth are experimental studies of the development of flint knapping to make functional sharp flakes by bonobos, implicating and defining the social learning and innovation involved. Finally, new and substantial experiments compare what different social learning processes, from observational learning to teaching, afford good quality human flake and biface manufacture. Together these complementary approaches begin to delineate the social learning processes necessary to percussive technologies within the Pan – Homo clade.

Complicated Conditions

This article considers the dichotomy between theory and life, treating it as a reflection of the process of subjectivization of discourse of the anthropological variety. In accord with the accepted premise, scientific theories do not emerge on their own but as result of complicated conditions at the meeting point of subjective-individual experience and the language of theory, leading to a close connection between the maker of given theory and the theory itself. In such a cognitive context, legitimacy is achieved by analytical-interpretative tasks, which consist in seeking meanings and discovering the sense of manifold signs of the presence of the human being in theory (thus someone real, who situates himself openly or covertly in the constructed descriptions of the world) and the theory in the human being, that is, the conceptual or otherwise indicated manifestations of self-understanding. An instructive exemplification of such analytical and interpretative work is the scientific autobiography of an outstanding Polish anthropologist, Czesław Robotycki, a scholar developing the contemporary theory of culture while taking into account cultural paradoxes and the attitude of anthropological distancing which were personally important to him.

Insight Into

Negative prefixing has always been an important and intriguing morphological process, through which adjectives are formed in many different languages. However, there are limits to negative prefixing. In this study, we introduce the novel concept of Polarity Flexibility, through which the limitations for the negative prefixing are accounted for. Furthermore, we conducted an experiment to investigate whether the PF is an active cognitive process. The results of the experiment confirm our hypothesis and the fact that Polarity Flexibility does indeed influence the cognitive processing. In our study, we introduce the notion of the syntactic arrangement which influences the negative prefixing. Therefore, we compare Russian, Persian, Spanish and English in negative prefixing to show how much the cognitive processes are influenced by the syntactic formations. Russian as a representative of Slavic languages brings an important insight into the way syntax plays role in the semantic-cognitive context.
