Phonemic codes are accorded a privileged role in most current models of immediate serial recall, although their effects are apparent in short-term proactive interference (PI) effects as well. The present research looks at how assumptions concerning distributed representation and distributed storage involving both semantic and phonemic codes might be operationalized to produce PI in a short-term...
Phonetic transcriptions are often manually encoded in a pronunciation lexicon. This process is time consuming and requires linguistic expertise. Moreover, it is very difficult to maintain consistency. To handle these problems, we present a model that produces Korean pronunciation variants based on morphophonological analysis. By analyzing phonological variations frequently found in spoken Korea...
We consider problems in sequence enumeration suggested by Stockhausen’s problem, and derive a generating series for the number of sequences of length k on n available symbols such that adjacent symbols are distinct, the terminal symbol occurs exactly r times, and all other symbols occur at most r − 1 times. The analysis makes extensive use of techniques from the theory of symmetric functions. E...
The simple deterministic grammar (s-grammar) is the standard form grammar in which the handles of the Z-rules are distinct for each nonterminal symbol Z. The language generated by an s-grammar is called the simple deterministic language (s-language). It is known that the s-languages have the the prefix property and that their equivalence problem is solvable. (Korenjak and Hopcroft, 1966). Using...
The purpose of this study was to investigate the role of the cerebellum in the executive control of word generation using a phonemic and semantic fluency task. Phonemic fluency tasks require novel strategy to organize verbal output, and are more effortful than semantic fluency tasks. The number of category switches made between subcategories of words is a measure of mental flexibility, and is g...
This study focuses on the early cerebral base of speech perception by examining functional lateralization in neonates for processing segmental and suprasegmental features of speech. For this purpose, auditory evoked responses of full-term neonates to phonemic and prosodic contrasts were measured in their temporal area and part of the frontal and parietal areas using near-infrared spectroscopy (...
In Japanese, vowel duration can distinguish the meaning of words. In order for infants to learn this phonemic contrast using simple distributional analyses, there should be reliable differences in the duration of short and long vowels, and the frequency distribution of vowels must make these differences salient enough in the input. In this study, we evaluate these requirements of phonemic learn...
Categorical perception is a pervasive phenomenon in phonemic identification and has been demonstrated in the last decades through behavioral experiments and, more recently, in neurophysiological studies. However, the precise neural mechanisms underlying the transformation of continuous physical properties into discrete phonemic units is still largely unknown. This paper presents a study that ai...
Four experiments used the psychological refractory period logic to examine whether integration of multiple sources of phonemic information has a decisional locus. All experiments made use of a dual-task paradigm in which participants made forced-choice color categorization (Task 1) and phoneme categorization (Task 2) decisions at varying stimulus onset asynchronies. In Experiment 1, Task 2 diff...
