Studies assessing how bilinguals recognize and process language(s) have mainly used visual or auditory word recognition paradigms using words that can belong to either language. Representations in the orthographic lexicon can then activate information about their respective sounds and/or meanings. Main Content. A developmental, interactive activation model of the word superiority effect. Semantic Priming Paired Presentation- read first item of pair Make lexical decision to second … Measuring Lexical Similarity The decisions which lead to the identification of a word entry are the result of a forced selection process, which assigns as default the entry which best matches the available cues. successful model of visual word recognition needs to incorporat e the assumption of “inter-activity,” that is, that the various components of the visual word recognition system (i.e., orthographic, phonological, semantic) mutually activate and inhibit each other while a word is being processed (see also Van Orden & Kloos, this volume). The major theories of visual word recognition posit that word recognition is achieved when a unique representation in the orthographic lexicon reaches a critical level of activation (Coltheart et al., 2001; Grainger & Jacobs, 1996; Perry et al., 2007). Introduction to the Logogen model and the Interactive Activation ModelA story made with Moovly, an easy and powerful online video animation tool. According to the dual route models, there are lexical and sublexical routes in word recognition. Scherf et al. The different levels interact such that representations at one level can activate or inhibit representations at other levels. This model is used to explain the word superiority effect (WSE) which refers to a phenomenon where people recognize letters more easily if presented within words as compared to isolated letters, and to letters presented within non-word (orthographically illegal, unpronounceable letter array) strings.

Instead, Klatt suggested that spoken words could be recognized directly from an analysis of the input power spectrum using a large network of diphones combined with a “backward beam search” technique like the one originally incorporated in HARPY that eliminated weak lexical candidates from further processing (Klatt, 1979). Written numerals may also recruit temporal areas involved in. These findings support nonselective access during word recognition. Moreover, although irregular words were associated with longer naming latencies than regular ones, this regularity effect was much stronger when irregular words (e.g., frost) had a low summed frequency of friends (e.g., cost, whose word body has an identical pronunciation to the experimental word) and a high summed frequency of enemies (e.g., most, whose word body has a different pronunciation from the experimental word). Figure 1. Dehaene proposes that retrieval of rote verbal arithmetic facts may be retrieved from a corticostriatal loop through the left basal ganglia, which is thought to store other linguistic material such as rhymes. The central feature of this model assumes that the processing of information during reading consists of series of levels corresponding to visual features, letters and words. The fact that similar written forms map onto disparate phonological forms makes mapping difficult, and in fact words that contain such inconsistent mappings between spelling and sound are more difficult to read than words that contain entirely consistent mappings. a curved shape for "C", horizontal and … The central feature of this model assumes that the processing of information during reading consists of series of levels corresponding to visual features, letters and words. Word shape The word recognition model, which says that words are recognised as complete units, is the oldest model in the psychological literature. Human behavior is highly variable and IAC models as described thus far are completely deterministic. … Spelling-to-sound correspondence is represented as different weightings on connections between these units. It failed to specify precisely the perceptual units used to map acoustic phonetic input onto logogens or how different sources of linguistic information are combined together to alter the activation levels of individual logogens. Rene Jaime-rivas. Some researchers have argued that written words have to be transformed into a sound representation in order to access semantic and syntactic information about the word. Furthermore, the baseline activation of a word affects how easily it is recognized. Instead, this theoretical approach emphasizes patterns of activation and connection among “nodes” in the network that encode orthographic and phonological units of given languages. 3.3.1 The interactive-activation model; 3.3.2 Neighborhood (N) effects; 3.3.3 Masked form priming effects; 3.4 Word recognition and the reading system. Although the earliest theories of visual word recognition claimed that words were recognized as wholes on the basis of their shapes (Cattell, 1886), there is a strong consensus among modern theories that words are recognized in a hierarchical manner on the basis of their constituents, as in the interactive-activation model (McClelland & Rumelhart, 1981; Rumelhart & McClelland, 1982) shown in Figure 21.1 and its subsequent variants (Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001; Grainger & Jacobs, 1996; Perry, Ziegler, & Zorzi, 2007). The sublexical route involves the GPC rules, and yields successful naming of regular words (e.g., mint) or pseudowords (e.g., fint), but would fail in naming of irregular words (e.g., pint). However, closer consideration of the data indicates that the N400 continues to be influenced by processes that precede the analysis of the conceptual/semantic content retrieved from long-term memory. In addition, the BIA model proposes top-down inhibition from the language node back to the word node. However, when bilinguals need to indicate whether a string of letters is an existing word in a specific language, these homographs are usually processed more slowly (e.g., Dijkstra et al., 1998). Some, such as Korean and Serbo-Croatian, employ perfectly regular mappings from spelling to sound, such that each sound in the language is represented by a single character. One example of a hybrid model of SWR is Klatt’s Lexical Access From Spectra (LAFS) model (Klatt, 1979), which relies extensively on real-speech input in the form of power spectra that change over time, unlike other models of SWR that rely on preprocessed coded speech signals as input.
