It has been shown that while multiple unrelated meanings of a word (e.g. bank) increase processing latency, polysemy, that is multiple related word senses (e.g. paper) produce faster responses (Rodd, Gaskell & Marslen-Wilson, 2002; Klepousniotou, 2002). The goal of this study was to explore the effect of polysemy on word processing in Serbian. The outcomes of three lexical decision experiments have shown that polysemous words are processed faster. In addition, lemma frequency and number of related senses did not interact. Finally, a measure that combines lemma frequency and number of related senses into a single metric is proposed. This measure is information residual, initially applied on derivational morphology (Moscoso del Prado Mart?n, Kostic & Baayen, 2004). In this study the information residual is a difference between the amount of information (bit) derived from lemma frequency and the entropy of a polysemic cluster. Since relative frequencies of different word senses of a given word in Serbian are currently not available, maximum entropy (log N) was used as an approximation. The outcome of this study indicates that cognitive system is sensitive not only to the entropy of derivational clusters, but polysemic clusters as well.

Mean Reaction Time

Processing of inflected Serbian verbs was investigated in two lexical decision experiments. Specifically, the following issues were addressed: a. does the adjectival system contain syntactic functions and meanings, and b. are adjectival gender and case cognitively relevant properties. Each of the above issues could be expressed in terms of alternative equations that generate the amount of information carried by inflected form of an adjective. The informational values were correlated with mean reaction time to inflected adjectival forms. The outcome of the two experiments indicated that number of syntactic functions/meanings is the obligatory term in the equation that generates the amount of information carried by an adjectival inflected form. However, unlike nouns, where the amount information was specified in terms of ratio between a. sum of frequencies of inflected cases encompassed by a given inflected form and b. sum of its functions/ meanings, equation for adjectives includes sum of frequency by number of syntactic functions/meanings ratios for cases encompassed by a given inflected adjectival form. This, on the other hand, suggests that cognitive system when processing inflected adjectives is to some extent sensitive to adjectival case. It was also demonstrated that cognitive system is not sensitive to adjective gender.

Verb Tense

Processing of Serbian inflected verbs was investigated in two lexical decision experiments. In the first experiment subjects were presented with five forms of future tense, while in the second experiment the same verbs were presented in three forms of present and future tense. The outcome of the first experiment indicates that processing of inflected verb is determined by the amount of information derived from the average probability per congruent personal pronoun of a particular verb form. This implies that the cognitive system is not sensitive to verb person per se, nor to the gender of congruent personal pronoun. Results of the second experiment show that for verb forms of different tenses, presented in the same experiment, the amount of information has to be additionally modulated by tense probability. Such an outcome speaks in favor of cognitive relevance of verb tense.

Overwhelming Evidence

A great bulk of research in the psycholinguistic literature has been dedicated to hemispheric organization of words. An overwhelming evidence suggests that the left hemisphere is primarily responsible for lexical processing. However, non-words, which look similar to real words but lack meaningful associations, is underrepresented in the laterality literature. This study investigated the lateralization of Turkish non-words. Fifty-three Turkish monolinguals performed a lexical decision task in a visual hemifield paradigm. An analysis of their response times revealed left-hemispheric dominance for non-words, adding further support to the literature. The accuracy of their answers, however, were comparable regardless of the field of presentation. The results were discussed in light of the psycholinguistic word processing views.

Cross Language

Three experiments using a priming lexical decision paradigm were conducted to examine whether cross-language activation occurs via decomposition during the processing of derived words in Korean–English bilingual readers. In Experiment 1, when participants were given a real derived word and an interpretable derived pseudoword (i.e., illegal combination of a stem and a suffix) in Korean as a prime, response times for the corresponding English-translated stem were significantly faster than when they had received an unrelated word. In Experiment 2, non-morphological ending pseudowords (i.e., illegal combination of a stem and an orthographic ending) were included, and this did not show a priming effect. In Experiment 3, non-interpretable derived pseudowords also yielded a significant priming effect just as the interpretable ones. These results together suggest that cross-language activation of morphologically complex words occurs independently of lexicality and interpretability.

Entropy Principle

The maximum entropy approach operating with quite general entropy measure and constraint is considered. It is demonstrated that for a conditional or parametrized probability distribution f(x|μ), there is a "universal" relation among the entropy rate and the functions appearing in the constraint. This relation allows one to translate the specificities of the observed behavior θ(μ) into the amount of information on the relevant random variable x at different values of the parameter μ. It is shown that the recently proposed variational formulation of the entropic functional can be obtained as a consequence of this relation, that is from the maximum entropy principle. This resolves certain puzzling points that appeared in the variational approach.

Swedish Data

A multiple methods approach was applied to the study of morphology on the processing of lexical items in Swedish. Data from slips-of-the-tongue, agrammatic speech production, agrammatic oral reading, and lexical decision experiments were used. The results indicate that whole word processing as well as morphological processing takes place in the different types of tasks. The type of processing seems to vary along a continuum, with whole word processing as the most commonly applied type in automatized and relatively simple processing (such as lexical decision for common Swedish words), whereas signs of morpheme-based processing appear less often, and perhaps in less automatized tasks (such as agrammatic speech production).

The effectiveness of an informing system is based upon several factors that include the perceptual limitations of the person receiving the information. This paper examines the perceptual limitation of the amount of information that may be processed by the human cognitive system when this information is displayed in parallel through multiple windows. The experiments show that a sequential presentation of information is more effective than a parallel one in information transfer of large amounts of information or highly complex information in cognitively demanding subjects like mathematics. These conclusions are informative to educational system designers of complex subjects.

Length Effects

Although it is well established that beginning readers rely heavily on phonological decoding, the overlap of the phonological pathways used in visual and auditory word recognition is not clear. Especially in transparent languages, phonological reading could use the same pathways as spoken word processing. In the present study, we report a direct comparison of lexical decision performance in the visual and auditory modality in beginning readers of a transparent language. Using lexical decision, we examine how marker effects of length and frequency differ in the two modalities and how these differences are modulated by reading ability. The results show that both frequency and length effects are stronger in the visual modality, and the differences in length effects between modalities are more pronounced for poorer readers than for better readers. This suggests that visual word recognition in beginning readers of a transparent language initially is based on phonological decoding and subsequent matching in the phonological lexicon, especially for poor readers. However, some orthographic processing seems to be involved already. We claim that the relative contribution of the phonological and orthographic route in beginning readers can be measured by the differences in marker effects between auditory and visual lexical decision.

Word Senses

A word in natural language can be polysemous, having multiple meanings, as well as synonymous, meaning the same thing as other words. Word sense induction attempts to find the senses of polysemous words. Synonymy detection attempts to find when two words are interchangeable. We combine these tasks, first inducing word senses and then detecting similar senses to form word-sense synonym sets (synsets) in an unsupervised fashion. Given pairs of images and text with noun phrase labels, we perform synset induction to produce collections of underlying concepts described by one or more noun phrases. We find that considering multi-modal features from both visual and textual context yields better induced synsets than using either context alone. Human evaluations show that our unsupervised, multi-modally induced synsets are comparable in quality to annotation-assisted ImageNet synsets, achieving about 84% of ImageNet synsets' approval.
