Image Communication journal homepage: High-dimensional indexing methods have been proved quite useful for response time Received 29 September improvement. Based on Euclidian distance, many of them have been proposed for Received in revised form applications where data vectors are high-dimensional. In this way, the proposed approach achieves high performances in Relevance feedback response time and in precision when dealing with high-dimensional and heterogeneous vectors.
Traditionally — and in standard generative linguistics — what you store is divided into grammar and lexicon, where grammar contains all the rules, and the lexicon is an unstructured list of exceptions.
We develop an alternative view in which rules of grammar are lexical items that contain variables, and in which rules have two functions. In their generative function, they are used to build novel structures, just as in traditional generative linguistics.
In their relational function, they capture generalizations over stored items in the lexicon, a role not seriously explored in traditional linguistic theory.
The result is a lexicon that is highly structured, with rich patterns among stored items. We further explore the possibility that this sort of structuring is not peculiar to language, but appears in other cognitive domains as well.
The differences among cognitive domains are not in this overall texture, but in the materials over which stored relations are defined — patterns of phonology and syntax in language, of pitches and rhythms in music, of geographical knowledge in navigation, and so on. The challenge is to develop theories of representation in these other domains comparable to that for language.
However, recent work on bilingualism has shown that the native language is much more dynamic than previously thought, demonstrating the plasticity of the language system to various patterns of language input and use. I will present data from behavioral, electrophysiological, and neuroimaging studies focusing on two major subsystems of language: First, I will examine how bilinguals choose the right words in spoken language given that lexical items in both languages are thought to compete for selection.
Next, I examine how integrated the syntactic systems are for bilinguals by probing the vulnerability of the syntactic system to undergo change.
Results across these studies reveal that bilinguals make use of all the linguistic tools at their disposal to efficiently produce and comprehend language. Further, this work uncovers characteristics of the language system that are difficult to obtain from work on monolinguals — that the language system adapts to various contexts and the demands placed on it in dynamic ways.
She received her Ph. Her work focuses on language processing in bilingualism and aging and how language is supported by other aspects of cognition. An important arena for testing this hypothesis has been the study of spatial frames of reference. Furthermore, when performing non-linguistic tasks e.
A common interpretation of these results is that language plays a significant role in restructuring fundamental domains, like space. Japanese and Miyako are members of the Japonic language family, are mutually unintelligible, and with respect to spatial frames of reference are structurally equivalent i.
Since Miyako speakers are rather well schooled and are fully bilingual Japanese-Miyako, studying their responses to the above psycholinguistic tasks provide an interesting opportunity for teasing apart linguistic from cultural factors influencing thought and cognition.
Funded by Japan Society for the Promotion of Science From information density in dialogue to language acquisition: This principle is no stranger to language processing. But how do we arrive at these predictions, and how do they influence our linguistic behavior? In this talk, I review some recent results from our lab that adopt predictive language models as they are commonly found in natural-language processing systems.
With these, we quantify information density in language via an entropy-like measure: A study of dialogue  shows that speakers systematically converge in their information density, revealing a topic structure.
I provide a closer look at how these models work and can be improved , and I examine whether a language model can be trained better by exposing it to a visual environment, akin to situated language acquisition that human L1 learners experience. Are language models a starting point for models of a cognitive process?
To this end, here we will expose one particular process that occurs in interaction: Though it is often not explicitly analyzed, repair is a relevant aspect of interaction to consider for its effects on the evolution of a communication system as well as how it demonstrates the moment-to-moment processing and negotiation of alignment in emerging communication.
We present data from various studies of language evolution in which we document how repair is carried out, the types of repair present, and their effect on novel signaling.Attention, Perception, Memory, He drew a distinction between memory process and memory structure. Ecologically valid research attempts to mirror more accurately what happens outside the laboratory.
It suggests that mental states can be replicated and studied by using computers. As an umbrella discipline. Lexical retrieval is the process by which we activate and select lexical representations as we speak.
implicit expectations about what happens next in our environment help us perceive and disambiguate a complex world. language development, language processing, language perception, language and memory, language and learning, language and. Cognition does not affect perception: Evaluating the evidence for “top-down” process being contained within perception itself, rather memory, not perception, improves detection of words related to morality.
In particular, the work done by moral. - Memory refers to the formations and processes that are used to store and retain information; there are three key processes involved, encoding, storage and retrieval.
The first process; encoding, involves focusing awareness and consciously applying selective attention on a limited range of stimuli or events.

While in the original task a search for solution involved perception, memory, and motor apparatus as an integral, organic whole, with the new task, a sort of functional barrier was erected between the perception-memory system, which is responsible for decision-making, and the motor system, which retained only an executive role.
