Evidence for early effects of sentence context on word segmentation
نویسندگان
چکیده
The present paper focuses on the segmentation of two-word phrases containing two closely competing lexical hypotheses. It is hypothesized that the bottom-up information, which also includes a mechanism called the Possible-Word Constraint, is explored first in segmenting these phrases. Non-sensory sentential information influences this process at a later stage and only shows an effect if the bottom-up information does not lead to one dominating interpretation. The results of the present experiment show that listeners can and do make use of contextual information at a relatively early moment, at which the two possible segmentations are both still active and the bottom-up information has not yet suppressed the acoustically inconsistent interpretation. Hence, it was concluded that both sensory and non-sensory information is employed to affect activation levels of competing lexical hypotheses at an early moment.

First Language Activation during Second Language Lexical Processing in a Sentential Context
Lexicalization-patterns, the way words are mapped onto concepts, differ from one language to another. This study investigated the influence of first language (L1) lexicalization patterns on the processing of second language (L2) words in sentential contexts by both less proficient and more proficient Persian learners of English. The focus was on cases where two different senses of a polys...

A cross-modal naming experiment was conducted to further verify the effects of context and other lexical information in the processing of Chinese homophones during spoken language comprehension. In this experiment, listeners named aloud a visual probe as fast as they could, at a pre-designated point upon hearing the sentence, which ended with a spoken Chinese homophone. Results further support ...

Phoneme recognition is one of the fundamental phases of automatic speech recognition. Coarticulation which refers to the integration of sounds, is one of the important obstacles in phoneme recognition. In other words, each phone is influenced and changed by the characteristics of its neighbor phones, and coarticulation is responsible for most of these changes. The idea of modeling the effects o...
متن کاملEvent-related brain potential evidence for early effects of neighborhood density in word recognition.
Orthographic neighborhood density (ND) has been shown to play an important role in lexical access. In this study, event-related potentials were recorded as participants read sentences terminating in a high or low ND word, which was either congruent or incongruent with the sentence context. High ND words elicited a significantly more positive-going waveform at 150-300 ms poststimulus onset than ...

Thisstudy sought to evaluate the learners' achievements with the visual learning style when exposed to the sentence making and word list approaches. On that account, 45 basic level participants who studied at the Iran Language Institute (ILI), Bushehr, took part in this research study. At the outset, the learners were given Barsch learning style inventory (1991) to determine the learners' learn...
