Whole Word

In Experiment I, two-syllable words were presented in a multi-channel tachisto-scope. The whole word (W), first syllable (S1), and second syllable (S2) were displayed independently according to various schedules of successive 50-ms exposures; the exposures were in immediate succession, with no break apparent to the subject. Accuracy of identifying the words was facilitated by presenting a syllable before or after the whole word (S1W, S2W or WS1, WS2) in comparison with presenting the whole word alone (W). Presentation of the whole word for 100 ms (WW) produced better performance than sequential presentation of the first syllable, the whole word, and the second syllable for 50 ms each (S1WS2); the whole-word presentation (WW) was also superior to the reverse sequence (S2WS1). In Experiment II, strings of random digits were presented in the formats of S1WS2, WW, and S2WS1. Unlike the results of Experiment I, performance in the sequential conditions was not different from that in the simultaneous condition. It was concluded that sequential tachistoscopic presentation does not affect identification of unrelated characters, although it does disrupt the process of word recognition. Three hypotheses to explain the disruption were discussed: distortion of phonological representation, interruption of medial letter clusters, and fragmentation of the whole word.

Better Than

Ten-year-old children who were shown pictures of objects immediately preceded by the object's name recalled the material no better than those exposed to the names of the stimuli alone. Both conditions yielded significantly poorer retention than those in which pictures alone were presented or pictures followed by their names. A second study replicated this result. In addition this demonstrated, by a picture and name recognition task, that the effects could not be due to subjects in the “name prior to picture” condition ignoring the pictorial component. These results were interpreted as contradicting the “double encoding” explanation of the superiority of pictures to names in free recall. Parallel visual and verbal encoding of a pictured object does not facilitate retention unless the verbal cue is actively elicited from the subject by the stimulus. The implications of this result for other studies which have employed either simultaneous or sequential presentation of pictures and names are briefly discussed.

Compound Word Recognition

AbstractThis study investigated the development of character transposition effects during Chinese compound word recognition via computer mouse movements instead of the conventional key presses. Empirical evidence to reveal the impacts of vocabulary knowledge, grade level, and whole word frequency on Chinese transposed-character effect is lacking. In the present study, we measured the transposed-character effect in two groups of Taiwanese children (second and fourth graders) in a mouse-tracking lexical-decision task including nonwords derived from real words by transposing two characters (e.g., “習學” from “學習” [learning]) and control nonwords in which two characters are replaced (e.g., “以修”). Our results indicate that participants showed longer mouse movement times and larger spatial attraction in recognizing transposed-character nonwords than in replaced-character nonwords, suggesting that the dominant role of whole-word representation in processing Chinese compound words. Our results also further demonstrate that how the degree of character transposition was affected by vocabulary knowledge, grade level, and word frequency.

Punjabi language is a tonal language belonging to an Indo-Aryan language family and has a number of speakers all around the world. Punjabi language has gained acceptability in the media & communication and therefore deserves to have a place in the growing field of automatic speech recognition which has been explored already for a number of other Indian and foreign languages successfully. Some work has been done in the field of isolated word speech recognition for Punjabi language, but only using whole word based acoustic models. A phone based approach has yet to be applied for Punjabi language speech recognition. This paper describes an automatic speech recognizer that recognizes isolated word speech and connected word speech using a triphone based acoustic model on the HTK 3.4.1 speech Engine and compares the performance with acoustic whole word model based ASR system. Word recognition accuracy of isolated word speech was 92.05% for acoustic whole word model based system and 97.14% for acoustic triphone model based system whereas word recognition accuracy of connected word speech was 87.75% for acoustic whole word model based system and 91.62% for acoustic triphone model based system.

The Visual Word Form Area (VWFA) is a cortical region that adapts to support fluent word recognition. Surprisingly, the region of ventrolateral occipitotemporal cortex that becomes VWFA is specialized for processing the motion of inanimate objects that change shape. Such motion is neurally analyzed as a temporal sequence of shape 'snapshots'. We have proposed that the VWFA develops in this region because letter representations are serially activated in occipitotemporal cortex during typical reading acquisition. Therefore, the region that analyzes inanimate shape sequences is recruited to recognize letter sequences. We discuss the implications of this account for developmental dyslexia. In particular, inability to focus attention down to a single letter may preclude the serial letter selection that typically drives VWFA formation. Such a deficit would also interfere with acquisition of cortical letter-phoneme connections. Instead, compensated dyslexics employ the ventromedial object-recognition system for whole-word recognition, and the subcortical procedural system for phonological decoding.

Six experiments are reported which examine the assertion that phonological recoding for the purpose of lexical access in visual word recognition is prevented or impaired by concurrent articulation (“articulatory suppression”). The first section of this paper selectively reviews the literature, and reports two experiments which fail to replicate previous work. The third experiment contrasts performance with visually presented words and with non-words. Latency measures show an effect of suppression that is specific to words, whilst error rates show an effect common to both words and non-words. The fourth experiment shows that if the task is changed from a judgement of rhyme (BLAME-FLAME) to one of homophony (AIL-ALE), the suppression effect seen in the latency data is eliminated, whilst error effects remain. It is suggested that, in addition to producing error effects that are not easily interpretable, suppression prevents or impairs a phonological segmentation process operating subsequent to the retrieval of whole word phonology (a process that is needed for rhyme judgement but not for one of homophony). Experiment V shows that while suppression has no effect on the time taken to decide if printed non-words sound like real words (e.g. PALLIS), error rates increase. Experiment VI shows that suppression has no effect on either RT or errors in the same task if subjects suppress at a slower rate than in Experiment V. It is suggested that there are at least two different phonological codes. Buffer storage and/or maintenance of phonologically coded information derived from print is affected by suppression; phonological recoding from print for the purpose of lexical access can be carried out without any interference from suppression.
