Beyond decomposition: Processing zero-derivations in English visual word recognition
2019
Four experiments investigate the effects of covert morphological complexity during visual word recognition. Zero-derivations occur in English in which a change of word class occurs without any change in surface form (e.g., a boat-to boat; to soak-a soak). Boat is object-derived and is a basic noun (N), whereas soak is action-derived and is a basic verb (V). As the suffix {-ing} is only attached to verbs, deriving boating from its base, requires two steps, boat(N) > boat(V) > boating(V), while soaking can be derived in one step from soak(V). Experiments 1 to 3 used masked priming at different prime durations to test matched sets of one- and two-step verbs for morphological (soaking-SOA…
How functional coupling between the auditory cortex and the amygdala induces musical emotion: a single case study.
2013
Music is a sound structure of remarkable acoustical and temporal complexity. Although it cannot denote specific meaning, it is one of the most potent and universal stimuli for inducing mood. How the auditory and limbic systems interact, and whether this interaction is lateralized when feeling emotions related to music, remains unclear. We studied the functional correlation between the auditory cortex (AC) and amygdala (AMY) through intracerebral recordings from both hemispheres in a single patient while she listened attentively to musical excerpts, which we compared to passive listening of a sequence of pure tones. While the left primary and secondary auditory cortices (PAC and SAC) showed …
Explorations on interactive interfaces using cuteness
2007
The experience of interactive systems can be a rather complex set of events. The perceptions appeal to the user's senses including visual, auditory, tactile, olfactory, and gustatory. Taken from a human factors approach, the sensitivity of the senses can be measured very closely and units of measurement arise from the "just noticeable difference." These differences can be mapped to the physics behind the stimuli and computer controlled systems very accurately provide sensation to the user through various user interfaces. The human mind also plays an important role in making sense of the experience not only from a physiological standpoint, but from a psychological and cultural reference poin…
Cloning and training collective intelligence with generative adversarial networks
2021
Industry 4.0 and highly automated critical infrastructure can be seen as cyber‐physical‐social systems controlled by the Collective Intelligence. Such systems are essential for the functioning of the society and economy. On one hand, they have flexible infrastructure of heterogeneous systems and assets. On the other hand, they are social systems, which include collaborating humans and artificial decision makers. Such (human plus machine) resources must be pre‐trained to perform their mission with high efficiency. Both human and machine learning approaches must be bridged to enable such training. The importance of these systems requires the anticipation of the potential and previously unknow…
Systems thinking and adult cognitive development
2020
This chapter explores the links between scientific systems approaches and adult cognitive development. First, it describes the premises and basic concepts of systems thinking. It then continues to give an overview of the history of systems approach and the development of the main models and theories from its roots, which lie in the natural sciences. This is followed by an examination of the three systems paradigms, namely, Closed Systems, Open Systems, and Dynamic Systems and their implications to research and operational interests, in addition to their explanatory power in today’s world. Second part of the chapter focuses on describing the intersections between the Dynamic Systems paradigm…
Prefix Stripping Re-Re-Revisited: MEG Investigations of Morphological Decomposition and Recomposition
2019
We revisit a long-standing question in the psycholinguistic and neurolinguistic literature on comprehending morphologically complex words: are prefixes and suffixes processed using the same cognitive mechanisms? Recent work using Magnetoencephalography (MEG) to uncover the dynamic temporal and spatial responses evoked by visually presented complex suffixed single words provide us with a comprehensive picture of morphological processing in the brain, from early, form-based decomposition, through lexical access, grammatically constrained recomposition, and semantic interpretation. In the present study, we find that MEG responses to prefixed words reveal interesting early differences in the la…
University Students´ Knowledge Construction during Face to Face Collaborative Writing
2014
Collaborative writing combines social processes of writing with cognitive knowledge construction processes, and thus may lead to deeper learning than individual working. This study examined students’ knowledge construction during face-to-face collaborative writing. University students (n = 21) prepared themselves for the collaborative task by reading about developmental theories in a course book and writing individual summaries of them. In small groups, the students discussed each others’ summaries and wrote a joint essay on one of the theories. The data comprise the students’ individual summaries (n = 21), the students’ discussions during the essay writing (8177 speech turns), and the stud…
Precise mapping of the Goodpasture epitope(s) using phage display, site-directed mutagenesis, and surface plasmon resonance.
2013
Goodpasture disease is an autoimmune disorder mediated by circulating autoantibodies against the noncollagenous-1 (NC1) domain of the alpha 3 chain of type IV collagen (alpha 3(IV)NC1). The structure of Goodpasture epitope(s) has been previously mapped into two main binding regions (E-A and E-B) of the alpha 3(IV)NC1 domain using a residue mutation approach on the highly related alpha 1(IV)NC1 domain. Here we combined phage display and surface plasmon resonance technology to more precisely localize the pathogenic binding sites. Peptides mimicking the Goodpasture epitope(s) were used to identify residues involved in autoantibody binding and found involvement of eight residues previously unre…
Generalized Braid Groups and Mapping Class Gropus
1997
Given a chord system of D2, we associate a generalized braid group, a surface and a homomorphism from this braid group to the mapping class group of the surface. We disprove a conjecture stated in an article by Perron and Vannier by showing that generally this homomorphism is not injective.
