Context specificity of both acquisition and extinction of a Pavlovian conditioned response
2016
It is widely held that the extinction of a conditioned response is more context specific than its initial acquisition. One proposed explanation is that context serves to disambiguate the meaning of a stimulus. Using a procedure that equated the learning histories of the contexts, we show that the memory of an appetitive Pavlovian association can be highly context specific despite being unambiguous. This result is inconsistent with predictions of the Rescorla–Wagner model of learning but in line with configural accounts of contextual control of behavior. We propose an explanatory model in which context serves to modulate the gain of associative strength and which expands upon the configural …
Contextual neural-network based spectrum prediction for cognitive radio
2015
Cognitive radio is the technique of effective electromagnetic spectrum usage important for future wireless communication including 5G networks. Neural networks are nature-inspired computational models used to solve cognitive radio prediction problems. This paper presents the use of contextual Sigma-if neural network in prediction of channel states for cognitive radio. Our results indicate that Sigma-if neural network confirms better predictions than Multilayer Perceptron (MLP) network and decreases sensing time for the benefit of the increase of the effectiveness of e-m spectrum usage.
Analysis of Socio-Spatial Differences in Germany for the Definition of Online Milieus
2017
This research paper is part of a research project that analyses the influence of socioeconomic variables on the usage of online social networks to provide quality ensured social media supported business transactions. The research in this paper contains the analysing of the online milieu groups from the Responsibility-Driven Individuals and the Digital Vanguards, which were defined 2012 as milieu groups for online users in Germany. Both target groups are part of the in Germany well-established approach of lifeworlds and milieus for the differentiation of groups in the society. With such a distinguishing of customer groups, the communication with agents in social media communication will be m…
Gestural Attributions as Semantics in User Interface Sound Design
2010
This paper proposes a gesture-based approach to user interface sound design, which utilises projections of body movements in sounds as meaningful attributions. The approach is founded on embodied conceptualisation of human cognition and it is justified through a literature review on the subject of interpersonal action understanding. According to the resulting hypothesis, stereotypical gestural cues, which correlate with, e.g., a certain communicative intention, represent specific non-linguistic meanings. Based on this theoretical framework, a model of a process is also outlined where stereotypical gestural cues are implemented in sound design.
Graphic syntax and representational development
2008
International audience; This chapter focuses specifically on the relationships between syntax and cognitive development, particularly representational development. Vinter, Picard and Fernandes promote the take-home message that changes in drawing behaviour during development result from changes in the size of the cognitive units or mental representations used to plan behaviour, and in the capacity to manage part-whole relationships. This hypothesis is first illustrated by reviewing studies in which children's adherence to the graphic rules when they copy elementary or complex figures is assessed. The authors also examine children's syntactical behaviour at a more global level, characterizin…

Multimodality: Art as a Meaning-Making Process
2021
AbstractThe authors of the book see multimodality as intrinsic to human communication and texts, and as consisting of a multiplicity of signs. This chapter discusses how this applies in educational settings, to examine how different modes of communication are intertwined and utilized in learning, including children’s creative learning practices. In this, the authors use the semiotic concepts that operate in all communicative contexts: Field, tenor, and mode. Through them, the authors view the CLLP as a space that enables social activities, exploration of cultural, social, and societal contents and topics, and the development of social relationships. All this occurs through various communica…
The meaning of biological signals.
2020
We introduce the virtual special issue on content in signalling systems. The issue explores the uses and limits of ideas from evolutionary game theory and information theory for explaining the content of biological signals. We explain the basic idea of the Lewis-Skyrms sender-receiver framework, and we highlight three key themes of the issue: (i) the challenge of accounting for deception, misinformation and false content, (ii) the relevance of partial or total common interest to the evolution of meaningful signals, and (iii) how the sender-receiver framework relates to teleosemantics.
La identidad de la diversidad funcional en la comunicación mediada por la tecnología
2017
El objeto de estudio de la investigación que a continuación se presenta gravita sobre el cambio ontológico que impone la tecnología en el ser humano. En concreto, el desarrollo de tecnologías de ayuda aplicadas a Sistemas Alternativos de Comunicación representa un interesante ejemplo de cómo dichos soportes actúan en la base de las interacciones sociales, la comunicación y, cómo esta mediación modifica la propia autoimagen e imagen social de la persona que la emplea. El presente estudio se centra en las personas con parálisis cerebral o enfermedad degenerativa neuronal y en la transformación identitaria que padecen al poderse comunicar con soportes autónomos de alta tecnología. La hipótesis…
