One astonishing capability of humans is to recognize thousands of different objects visually, and to learn the semantic association between those objects and words referring to them. This work is an attempt to build a computational model of such capacity, simulating the process by which infants learn how to recognize objects and words through exposure to visual stimuli and vocal sounds. One of ...

The Object Naming Service (ONS) is a central lookup service of the EPCglobal Network. Its main function is the address retrieval of manufacturer information services for a given Electronic Product Code (EPC) identifier. This allows dynamic and globally distributed information sharing for items equipped with RFID tags compatible to EPCglobal standards. However, unlike in the DNS system, the ONS ...

Using longitudinal data on the Boston Naming Test ( Kaplan, Goodglass, & Weintraub, 1983) collected over 20 years from healthy individuals aged 30 to 94, we examined change in lexical retrieval with age, gender, education, and their interactions. We compared results between random-effects longitudinal and traditional cross-sectional models. Random-effects modeling revealed significant linear an...

PURPOSE This study tested the hypothesis that depth of semantic representation influences toddlers' word retrieval. METHOD Nineteen toddlers participated under 3 word learning conditions in this longitudinal study. Gestures cued attention to object shape (SHP) or function (FNC) in the experimental conditions. No semantic cue was provided under a control condition (CTL). Word learning conditio...

Much research has demonstrated a shape bias in categorizing and naming solid objects. This research has shown that when an entity is conceptualized as an individual object, adults and children attend to the object's shape. Separate research in the domain of numerical cognition suggest that there are distinct processes for quantifying small and large sets of discrete items. This research shows t...

Cognitive mechanisms underlying repetition priming in picture naming were decomposed in several experiments. Sets of encoding manipulations meant to selectively prime or reduce priming in object identification or word production components of picture naming were combined factorially to dissociate processes underlying priming in picture naming. Experiments 1, 2, and 3 were conducted with Spanish...

Most people find it profoundly difficult to name familiar smells. This difficulty persists even when perceptual odor processing and visual object naming are unimpaired, implying deficient sensory-specific interactions with the language system. Here we synthesize recent behavioral and neuroimaging data to develop a biologically informed framework for olfactory lexical processing in the human bra...

Rather than having universal linguistic categories for sets of common objects, languages develop their own, idiosyncratic naming patterns for them. Accounting for these patterns requires reference not only to the understanding of stimulus properties by individual speakers of a language, but also to the linguistic and cultural histories of the language they speak. To better understand how these ...

Patterns of object naming often differ between languages, but bilingual speakers develop convergent naming patterns in their two languages that are distinct from those of monolingual speakers of each language. This convergence appears to reflect interactions between lexical representations for the two languages. In this study, we developed a self-organizing connectionist model to simulate seman...

Learning to name objects is no sinecure. Children’s initial word use often will not correspond to the adult use of the same word. We suggest that semantic development may continue well past the early years of language acquisition, even for names for concrete objects. We studied evolution of the use of common nouns taking place during later lexical development. Children aged 5, 8, 10, 12 and 14 ...
