Orthographic Consistency Affects Spoken Word Recognition at Different Grain-Sizes

A number of previous studies found that the consistency of sound-to-spelling mappings (feedback consistency) affects spoken word recognition. In auditory lexical decision experiments, words that can only be spelled one way are recognized faster than words with multiple potential spellings. Previous studies demonstrated this by manipulating feedback consistency of rhymes. The present lexical decision study, done in English, manipulated the spelling of individual vowels within consistent rhymes. Participants recognized words with consistent rhymes where the vowel has the most typical spelling (e.g., lobe) faster than words with consistent rhymes where the vowel has a less typical spelling (e.g., loaf). The present study extends previous literature by showing that auditory word recognition is affected by orthographic regularities at different grain sizes, just like written word recognition and spelling. The theoretical and methodological implications for future research in spoken word recognition are discussed.     

Feedforward and feedback consistency effects for high- and low-frequency words in lexical decision and naming

In three experiments, we examined feedforward and feedback consistency effects in word recognition. Feedforward consistency is the degree to which a word's pronunciation is consistent with that of similarly spelled words, and feedback consistency refers to whether there is more than one way to spell a pronunciation. Previously, Stone, Vanhoy, and Van Orden (1997) reported feedforward and feedback consistency effects for low-frequency words in a lexical decision task. We investigated the effect of feedforward and feedback consistency for both high- and low-frequency words in lexical decision and naming. In both tasks, we found that feedforward and feedback inconsistent words were processed more slowly than consistent words, regardless of word frequency. These findings indicate that both types of consistency are involved in visual word recognition.     

Naming multisyllabic words

The process of reading multisyllabic words aloud from print was examined in 4 experiments. Experiment 1 used multisyllabic words that vary in terms of the consistency of component spelling-sound correspondences. The stimuli were regular, regular inconsistent, and exception words analogous to the monosyllabic items used in previous studies. Both regular inconsistent and exception words produced longer naming latencies than regular words. In Experiment 2 these differences between word types were found to be limited to lower frequency items. Experiment 3 showed that effects of number of syllables on naming latency are also limited to lower frequency words when the stimulus display forced subjects to use syllabic units. Thus, frequency modulates the effects of two aspects of lexical structure-consistency of spelling-sound correspondences and number of syllables. The results suggest that the naming of multisyllabic words draws on some of the same knowledge representations and processes as monosyllabic words; however, naming does not require syllabic decomposition. The results are discussed in the context of current models of naming.     

Additive and interactive effects of word frequency and masked repetition in the lexical decision task

In previous studies, additive effects of masked repetition and word frequency on lexical decision latency have been reported. This additive pattern was replicated in Experiment 1 with the use of lowfrequency words (range, 1–7 per million) selected at random. In contrast, in Experiment 2, in which low-frequency words known to be familiar to the subjects were used, the masked repetition priming effect was greater for low-frequency than for high-frequency words. It is suggested that the absence of an interaction between masked repetition and frequency observed in previous studies and in the present Experiment 1 was due to the fact that very-low-frequency words often have an unstable representation in the subjects’ lexicon and, consequently, sometimes fail to produce repetition priming effects in full.

Searching for a word in Chinese text: insights from eye movement behaviour

Locating relevant information in text is an important aspect of the reading process, however relatively few studies have examined this, especially for logographic languages such as Chinese. The present study examines eye movement behaviour during search for a target word in Chinese sentences, compared with reading the sentences for comprehension. Although there were clear effects of word frequency during reading for comprehension, the study shows no evidence for an influence of the word frequency of non-target words on eye movement behaviour during target word search. The results are in line with previous research undertaken in English (Rayner, K., & Fischer, M. H. (1996). Mindless reading revisited: Eye movements during reading and scanning are different. Perception & Psychophysics, 58, 734–747.), such that during search for a target word, eye movement behaviour for non-target words is largely driven by superficial processing of those words. The study also highlights the prevalence of word skipping, indicating that words are often sampled only in visually degraded parafoveal vision during target word search in Chinese.     

汉字亚词汇部件语音加工的P200效应

亚词汇加工是词汇识别研究中的一个重要领域,本研究考察了早期ERP成分P200如何受到汉字亚词汇部件语音信息的影响。在ERP实验中,被试对顺序呈现的启动字和目标字对进行语义判断。实验中“启动字-目标字”字对共享一个共同的可发音或不可发音的部件（如“吹-砍”、“扬-场”）。对目标字的P200效应分析显示：与部件不发音的目标字相比,部件可发音的目标字所诱发的P200显著增强。这种增强的ERP效应表明P200对汉字识别中亚词汇部件的语音加工非常敏感,其效应变化受到亚词汇语音的单独调节,同时也表明在汉字识别的早期阶段亚词汇部件语音信息就已被激活并在汉字加工中起重要作用。     

Absence of syllable effects: multisyllabic [correction of monosyllabic] words are easier than monosyllabic [correction of multisyllabic] words.

The role of syllables using the conventional lexical task of naming was examined with 107 college students. Equal numbers of four- and six-letter mono syllabic and multisyllabic words were presented for naming. There were significant syllable effects for 4-letter words as in previous studies but not for 6-letter words. In stead, monosyllabic words take more time to process than multisyllabic words. Most monosyllabic words are exceptional words with irregular correspondence of letter to sound. These results confirm that letter-to-sound consistency is more important in word recognition than the number of syllables.     

The locus of word frequency effects in skilled spelling-to-dictation

In spelling-to-dictation tasks, skilled spellers consistently initiate spelling of high-frequency words faster than that of low-frequency words. Tainturier and Rapp's model of spelling shows three possible loci for this frequency effect: spoken word recognition, orthographic retrieval, and response execution of the first letter. Thus far, researchers have attributed the effect solely to orthographic retrieval without considering spoken word recognition or response execution. To investigate word frequency effects at each of these three loci, Experiment 1 involved a delayed spelling-to-dictation task and Experiment 2 involved a delayed/uncertain task. In Experiment 1, no frequency effect was found in the 1200-ms delayed condition, suggesting that response execution is not affected by word frequency. In Experiment 2, no frequency effect was found in the delayed/uncertain task that reflects the orthographic retrieval, whereas a frequency effect was found in the comparison immediate/uncertain task that reflects both spoken word recognition and orthographic retrieval. The results of this two-part study suggest that frequency effects in spoken word recognition play a substantial role in skilled spelling-to-dictation. Discrepancies between these findings and previous research, and the limitations of the present study, are discussed.     

How are number words mapped to approximate magnitudes?

How do we map number words to the magnitudes they represent? While much is known about the developmental trajectory of number word learning, the acquisition of the counting routine, and the academic correlates of estimation ability, previous studies have yet to describe the mechanisms that link number words to nonverbal representations of number. We investigated two mechanisms: associative mapping and structure mapping. Four dot array estimation tasks found that adults' ability to match a number word to one of two discriminably different sets declined as a function of set size and that participants' estimates of relatively large, but not small, set sizes were influenced by misleading feedback during an estimation task. We propose that subjects employ structure mappings for linking relatively large number words to set sizes, but rely chiefly on item-by-item associative mappings for smaller sets. These results indicate that both inference and association play important roles in mapping number words to approximate magnitudes.     

Norms of subjective frequency of use and imagery for a sample of 1,916 French nouns.

Norms of rated subjective frequency of use and imagery on seven-point scales are reported for 1,916 French nouns. Subjective frequency was defined as the rated frequency of occurrence of words in spoken French, and imagery was defined as the rated case with which a word aroused a mental image. The mean, standard deviation, and percentile rank of the frequency and imagery ratings for each item are presented in the Appendix together with their objective frequency of occurrence in Baudot's (1992) dictionary. Interjudge reliability was assessed by calculating the correlation between the mean ratings of items repeated in the booklet, between the mean ratings obtained from odd-numbered and even-numbered respondents, and by computing the Cronbach alpha statistic for each page of the booklet. These reliability estimates were equal to or greater than .92 for frequency and for imagery, confirming the high level of interjudge consistency. Although the estimates provided by female and male participants were highly correlated (r = .97), the former gave a slightly higher frequency rating to the word sample but a slightly lower imagery rating than the latter did. Moreover, female respondents gave slightly more extreme ratings on the frequency and imagery scales. An analysis of the absolute difference between female and male ratings revealed a discrepancy of one half point or more on 20% of the word sample for frequency and 13% for imagery. On both scales, the mean absolute difference between male and female ratings was larger than that obtained by chance alone. This finding highlights the possibility that some words may not be equally familiar to women and men or may not evoke imagery with the same ease in these groups. Validity estimates for the frequency and imagery ratings were derived from correlations with scale values drawn from other normative studies. These correlation coefficients were equal to or greater than .78 for frequency and .86 for imagery, confirming the high level of consistency between this and other studies. An analysis of the relationship between subjective frequency and imagery ratings indicated that these variables are generally uncorrelated but exceptions occur. In the present study the coefficient of the correlation between subjective frequency and imagery was .24. However, when items with extreme mean frequency were excluded from the calculation, the correlation coefficient dropped to .04 and was no longer significant. Imagery ratings from five independent studies were all positively and significantly correlated with Vikis-Freibergs's (1974) frequency estimates, which were obtained from a free-association task. This finding suggests that word association, as a form of cued recall, may be influenced by several stimulus attributes including prior frequency of association and imagery-evoking value. The pattern of correlation between imagery ratings and text-based frequency estimates is not coherent. It reveals significant correlations only in select cases and no consistent polarity of linear relationship. The main contribution of this research is to provide reliable estimates of subjective frequency and imagery value for a word sample that is larger than those included in previous studies. A close examination of the linear relationship among the various sources of frequency and imagery data underscores the risk of confounding these variables in the selection of lexical stimuli for research.

Feedback consistency effects in visual and auditory word recognition: where do we stand after more than a decade?

The role of phonology-to-spelling consistency (i.e., feedback consistency) was investigated in 3 lexical decision experiments in both the visual and auditory modalities in French and English. No evidence for a feedback consistency effect was found in the visual modality, either in English or in French, despite the fact that consistency was manipulated for different kinds of units (onsets and rimes). In contrast, robust feedback consistency effects were obtained in the auditory lexical decision task in both English and French when exactly the same items that produced a null effect in the visual modality were used. Neural network simulations are presented to show that previous demonstrations of feedback consistency effects in the visual modality can be simulated with a model that is not sensitive to feedback consistency, suggesting that these effects might have come from various confounds. These simulations, together with the authors' results, suggest that there are no feedback consistency effects in the visual modality. In contrast, such effects are clearly present in the auditory modality. Given that orthographic information is absent from current models of spoken word recognition, the present findings present a major challenge to these models.     

Age changes in the missing-letter effect revisited

When participants search for a target letter while reading, they make more omissions if the target letter is embedded in frequent function words than in less frequent content words. Reflecting developmental changes in component language and literacy skills, the size of this effect increases with age. With adults, the missing-letter effect is due to both word function and word frequency. With children, it is unclear whether the growing size of the missing-letter effect across development is due to a larger effect of word function, word frequency, or both because previous studies with children seeking to isolate the influence of word frequency and word function suffer from important methodological limitations. With these methodological limitations eliminated (Experiments 1 and 2), performance in a letter detection task was assessed for children in Grades 1, 2, 3, 4, and 7 as well as for undergraduate students. The results revealed that the influence of word function increases with age, whereas the effect of frequency is fairly stable across ages. Furthermore, normative predictability data collected in Experiment 3 revealed that third graders and undergraduate students were equally good at predicting function slots in a sentence.     

The Project Method of Teaching Psychology: A Rejoinder to Dr. Cason

Unlike word frequency counts—e.g., Thorndike and Lorge—or nonsense syllable norms, the total number of different words scaled in extant norms with free associations is limited, although some words were repeatedly scaled. In order to remedy this situation and broaden the word pool for future research, a new norm for 48 words was obtained by means of free associations in the present study (N = 58 men and women undergraduate students in psychology). Discrete normative free associations were procured for 10 words for the first time by the current norm. For the words previously scaled, whereas there were some noticeable differences, overall substantial consistency was observed between the present and earlier results. Further, a survey of previously available word association norms disclosed useful information and interesting trends in this field.     

Comparison of Different Feedback Procedures in Second Language Vocabulary Learning

Research into the learning of Second Language (SL) vocabulary by beginning learners has indicated that the simultaneous presentation of the First and Second Language words results in blocking of the learning process by the familiar First Language (FL) word. Previous research also suggests that blocking by the First Language can be eliminated by bringing it in as informative feedback (either as a written or spoken word). Our experiments were designed to further extend this research. The use of a picture, either as feedback or simultaneously presented with its equivalent, along with the aural feedback and the conventional procedures were investigated in Experiment 1. Results revealed that pictures blocked the learning process less than the written FL word when both were presented with their SL referent. When used as feedback, however, pictures were not as good as the spoken FL word. Experiment 2 demonstrated that aural feedback was the best type of feedback when compared with the picture and written FL presentations, and that the picture feedback was better than the written feedback. Taken together, the results of these two studies showed that all forms of feedback overcame the problem of blocking created by simultaneous presentation of the FL and SL words, and that aural feedback was the most effective feedback procedure. It was suggested that the superiority of aural feedback was likely to be a consequence of the use of a different input channel to that of the visually presented written SL word.     

Parafoveal-on-foveal interactions in word recognition

An experiment is reported in which participants read sequences of five words, looking for items describing articles of clothing. The third and fourth words in critical sequences were defined as "foveal" and "parafoveal" words, respectively. The length and frequency of foveal words and the length, frequency, and initial-letter constraint of parafoveal words were manipulated. Gaze and refixation rate on the foveal word were measured as a function of properties of the parafoveal word. The results show that measured gaze on a given foveal word is systematically modulated by properties of an unfixated parafoveal word. It is suggested that apparent inconsistencies in previous studies of parafoveal-on-foveal effects relate to a failure to control for foveal word length and hence the visibility of parafoveal words. A serial-sequential attention-switching model of eye movement control cannot account for the pattern of obtained effects. The data are also incompatible with various forms of parallel-processing model. They are best accounted for by postulating a process-monitoring mechanism, sensitive to the simultaneous rate of acquisition of information from foveal and parafoveal sources.     

Perceived frequency of concrete and abstract words

Studies are reported which show that concrete and abstract words of equal objective frequency (based on available , word counts) are not perceived as being equal. The abstract word has greater perceived frequency than the concrete word. The judged variety of contexts in which a word appears correlates very highly with perceived frequency. The results have relevance to the design of learning studies in which concrete and abstract words are used. and also to the interpretation of such experiments.     

Investigating word class effects in first and second languages

According to Zyzik in 2009, only a few recent studies have investigated similarities in use of words in comprehension of first languages (L1) and second languages (L2). Furtner, Rauthmann, and Sachse showed a rank order of word classes by frequency of eye-gaze regression when reading other difficult words: nouns, adjectives, closed-class words, verbs. The hypothesis was that a L1-L2 word-class similarity effect between German (L1) and English (L2) would occur, and this was tested with jumbled word reading of English text (wherein letters within words Shave been jumbled) and eye-tracking by 141 participants. Analyses of regressive fixations from one word class to others showed that nouns were regressed most often and there was a rank order of importance among the word classes apparently used to enhance comprehension of other difficult words (nouns, adjectives, verbs, dosed-class words). Thus, previous findings for L1 were largely replicated. Findings are discussed regarding language acquisition.
