The Impact of Sonority on Onset-Rime and Peak-Coda Lexical Decision and Naming of Lexical Items by Children with Different Spelling Ability

The present study used the lexical decision (making YES/NO decision) and the vocalization (naming) paradigms in two reaction time experiments to examine the cohesiveness of onset-rime and peak-coda in the syllable structure of English lexical items. The aim was to study the effect of sonority hierarchy of liquids, nasals and obstruents on the accurate and rapid identification and naming of CCVCC words and pseudowords in relation to the spelling performance of 222 grades 4, 5 and 6 students. In the onset-rime lexical decision and naming tasks nasals were processed faster than the liquids and the obstruents. In the peak-coda lexical decision and naming the obstruents were processed faster than the liquids and nasals. The reaction time results suggest relationship with the spelling of English words even though the significant main effects of grade, spelling performance, mode of response and lexicality of the stimulus items need to be interpreted in the context of statistical interactions.     

The Differential Influence of Lexical Parameters on Naming Latencies in German. A Study on Noun and Verb Picture Naming

The present study investigates the effects of word category (nouns versus verbs) and their subcategories on naming latencies in German, with a focus on the influence of lexical parameters on naming performance. The experimental material met linguistic construction criteria and was carefully matched for age of spontaneous production, frequency, and name agreement. Additional lexical parameters (objective age-of-acquisition, word length, visual complexity, imageability) were obtained. The results demonstrated a clear effect of word category on naming latencies. This effect was supported by two different observations. First, there was evidence for category and subcategory effects in naming: nouns were named faster than verbs, and intransitive verbs were named faster than transitive verbs. Second, while objective age-of-acquisition (naming age) turned out to be an important predictor of reaction times for both word categories, naming latencies for nouns and verbs were affected differentially by other lexical parameters. The results are discussed with respect to current controversies on the noun-verb-asymmetry.     

起始音素的特点对命名反应时记录的影响

通过对344个汉语单字词26名被试的平均命名反应时分析发现,起始音素不同的词的命名反应时之间存在差异,而且此差异在排除字频、获得年龄(Age of acquisition)、规则性、一致性、可表象性、笔画数、书面学习年龄、声旁成字频率等因素作用后仍然存在。起始音素为元音和浊辅音的字词比清辅音的字词反应时短,清辅音当中塞擦音反应时最长。讨论了这种差异的可能原因,并对字词命名实验提出了相关建议。     

Visual rapid naming and phonological abilities: different subtypes in dyslexic children

One implication of the double-deficit hypothesis for dyslexia is that there should be subtypes of dyslexic readers that exhibit rapid naming deficits with or without concomitant phonological processing problems. In the current study, we investigated the validity of this hypothesis for Portuguese orthography, which is more consistent than English orthography, by exploring different cognitive profiles in a sample of dyslexic children. In particular, we were interested in identifying readers characterized by a pure rapid automatized naming deficit. We also examined whether rapid naming and phonological awareness independently account for individual differences in reading performance. We characterized the performance of dyslexic readers and a control group of normal readers matched for age on reading, visual rapid naming and phonological processing tasks. Our results suggest that there is a subgroup of dyslexic readers with intact phonological processing capacity (in terms of both accuracy and speed measures) but poor rapid naming skills. We also provide evidence for an independent association between rapid naming and reading competence in the dyslexic sample, when the effect of phonological skills was controlled. Altogether, the results are more consistent with the view that rapid naming problems in dyslexia represent a second core deficit rather than an exclusive phonological explanation for the rapid naming deficits. Furthermore, additional non-phonological processes, which subserve rapid naming performance, contribute independently to reading development.     

Prior sensitivity in theory testing: An apologia for the Bayes factor

A commonly voiced concern with the Bayes factor is that, unlike many other Bayesian and non-Bayesian quantitative measures of model evaluation, it is highly sensitive to the parameter prior. This paper argues that, when dealing with psychological models that are quantitatively instantiated theories, being sensitive to the prior is an attractive feature of a model evaluation measure. This assertion follows from the observation that in psychological models parameters are not completely unknown, but correspond to psychological variables about which theory often exists. This theory can be formally captured in the prior range and prior distribution of the parameters, indicating which parameter values are allowed, likely, unlikely and forbidden. Because the prior is a vehicle for expressing psychological theory, it should, like the model equation, be considered as an integral part of the model. It is argued that the combined practice of building models using informative priors, and evaluating models using prior sensitive measures advances knowledge.     

TDQ-60 – a color picture-naming test for adults and elderly people: validation and normalization data

Word-finding difficulties are usually assessed with picture-naming tests. In this article, we present the TDQ-60, a new test designed to assess acquired lexical access deficits, taking into account semantics and psycholinguistic variables. The article includes three studies. Study 1 describes the development phase of the TDQ-60. In study 2, healthy control participants and individuals with a diagnosis of the semantic variant of primary progressive aphasia were assessed to establish the convergent and discriminant validity of the TDQ-60. Finally, in Study 3, a group of 305 young and elderly French-speaking adults from Quebec were assessed in order to provide normative data. The results demonstrate that the TDQ-60 has good convergent validity and good discriminant validity. This study also provides normative data in which were considered the effect of age and education.The TDQ-60 is a new valid picture-naming test, controlled for psycholinguistic variables and designed to identify the influence of semantics on lexical access in spoken production.     

Letter Writing: A Creative Tool for School Counselors Working with Adolescents

Letter writing is a therapeutic tool used in many helping professions with many populations. In school counseling, letter writing can be a useful way for school counselors to build relationships and assess student needs. Letter writing may appeal to students who are more introspective and prefer less direct forms of communication (France, Cadieax, & Allen, 1995). Evidence to support school counselors’ use of letter writing with students is underdeveloped. Citing conceptual, empirical, and theoretical support, the authors propose prompting students to write Letters About Themselves (LAT) at the beginning, middle, and end phases of the school year. Considerations for school counselors using letter writing with adolescents are explored.     

Developmental changes in neural letter‐selectivity: A 1‐year follow‐up of beginning readers

The developmental course of neural tuning to visual letter strings is unclear. Here we tested 39 children longitudinally, at the beginning of grade 1 (6.45 ± 0.33 years old) and 1 year after, with fast periodic visual stimulation in electroencephalography to assess the evolution of selective neural responses to letter strings and their relationship with emerging reading abilities. At both grades, frequency‐tagged letter strings were discriminated from pseudofont strings (i.e. letter‐selectivity) over the left occipito‐temporal cortex, with effects observed at the individual level in 62% of children. However, visual words were not discriminated from pseudowords (lexical access) at either grade. Following 1 year of schooling, letter‐selective responses showed a specific increase in amplitude, a more complex pattern of harmonics, and were located more anteriorly over the left occipito‐temporal cortex. Remarkably, at both grades, neural responses were highly significant at the individual level and correlated with individual reading scores. The amplitude increase in letter‐selective responses between grades was not found for discrimination responses of familiar keyboard symbols from pseudosymbols, and was not related to a general increase in visual stimulation responses. These findings demonstrate a rapid onset of left hemispheric letter selectivity, with 1 year of reading instruction resulting in increased emerging reading abilities and a clear quantitative and qualitative evolution within left hemispheric neural circuits for reading.     

Reading and related skills in Grades 6, 7, 8 and 9: French normative data from EVALEC

IntroductionTo appropriately assess reading difficulties, tests designed according to an appropriate theoretical framework and based on normative data are required.ObjectiveWe used EVALEC (Sprenger-Charolles, Colé, Béchennec, & Kipffer-Piquard, 2005) to collect data on the word-level reading skills and reading-related skills (phonemic awareness, phonological short-term memory, and rapid naming) of middle school children (Grades 6 to 9, about 80 in each grade).MethodIn the tests focused on word-level reading skills, the effects of regularity (regular vs. irregular words), lexicality, and length (short vs. long irregular words and pseudowords) were examined. Accuracy and processing times were recorded for all tests.ResultsThe effects of both regularity and lexicality were significant, whatever the measure and independently of grade. Both accuracy and speed were lower for longer pseudowords, whereas length did not have a significant effect on irregular word latencies and, surprisingly, long irregular words were read more accurately than short ones. Reading level as assessed by a standardized test (Lefavrais, 2005) was not predicted by phonological short-term memory; rapid naming (color names) and phonemic awareness were both predictors but, in both cases, only response times predicted reading level.ConclusionThese results, and particularly those from the reading tasks, are discussed in relation to models of written-word recognition developed to account for the reading of multisyllabic items (Perry, Ziegler, & Zorzi, 2010) in orthographies shallower than English (Perry, Ziegler, & Zorzi, 2014).     

The effects of thematic relations on picture naming abilities across the lifespan

A picture–word interference paradigm tracked patterns of activation during picture naming in 87 individuals (age range 17–80 years old). Distractor words were presented at stimulus onset asynchronies (SOAs) of ?200, ?100, and 0 ms bearing a has a-, location, or no relationship to the picture. Analyses of group naming reaction times revealed significant facilitation effects for both semantic relation types for all age groups. Analyses of temporal patterns of activation revealed significant effects primarily at SOAs of ?200 and ?100 ms. These findings provide evidence that both thematic relations are particularly salient in how semantic knowledge is organized, and that the patterns of effects from these semantic relations remain the same as one ages.
