Contextual diversity is a main determinant of word identification times in young readers.
2013
Recent research with college-aged skilled readers by Adelman and colleagues revealed that contextual diversity (i.e., the number of contexts in which a word appears) is a more critical determinant of visual word recognition than mere repeated exposure (i.e., word frequency) (Psychological Science, 2006, Vol. 17, pp. 814-823). Given that contextual diversity has been claimed to be a relevant factor to word acquisition in developing readers, the effects of contextual diversity should also be a main determinant of word identification times in developing readers. A lexical decision experiment was conducted to examine the effects of contextual diversity and word frequency in young readers (child…
Lexical and grammatical development in children at family risk of dyslexia from early childhood to school entry: a cross-lagged analysis.
2019
AbstractThe aim of this study was to examine (a) the development of vocabulary and grammar in children with family-risk (FR) of dyslexia and their peers with no such risk (NoFR) between ages 1;6 and 6;0, and (b) whether FR-status exerted an effect on the direction of temporal relationships between these two constructs. Groups were assessed at seven time-points using standardised tests and parental reports. Results indicated that although FR and NoFR children had a similar development in the earlier years, the FR group appeared to perform significantly more poorly on vocabulary at the end of the preschool period. Results showed no significant effect of FR status on the cross-lagged relations…
Does visual letter similarity modulate masked form priming in young readers of Arabic?
2018
Available online 19 January 2018 Supplementary data associated with this article can be found, in the online version, at https://doi. org/10.1016/j.jecp.2017.12.004. Supplementary data associated with this article can be found, in the online version, at https://doi. org/10.1016/j.jecp.2017.12.004. We carried out a masked priming lexical decision experiment to study whether visual letter similarity plays a role during the initial phases of word processing in young readers of Arabic (fifth graders). Arabic is ideally suited to test these effects because most Arabic letters share their basic shape with at least one other letter and differ only in the number/position of diacritical points (e.g.…
Contextual diversity facilitates learning new words in the classroom.
2017
Published: June 6, 2017 In the field of word recognition and reading, it is commonly assumed that frequently repeated words create more accessible memory traces than infrequently repeated words, thus capturing the word-frequency effect. Nevertheless, recent research has shown that a seemingly related factor, contextual diversity (defined as the number of different contexts [e.g., films] in which a word appears), is a better predictor than word-frequency in word recognition and sentence reading experiments. Recent research has shown that contextual diversity plays an important role when learning new words in a laboratory setting with adult readers. In the current experiment, we directly mani…
Computer game as a tool for training the identification of phonemic length.
2013
Computer-assisted training of Finnish phonemic length was conducted with 7-year-old Russian-speaking second-language learners of Finnish. Phonemic length plays a different role in these two languages. The training included game activities with two- and three-syllable word and pseudo-word minimal pairs with prototypical vowel durations. The lowest accuracy scores were recorded for two-syllable words. Accuracy scores were higher for the minimal pairs with larger rather than smaller differences in duration. Accuracy scores were lower for long duration than for short duration. The ability to identify quantity degree was generalized to stimuli used in the identification test in two of the childr…
Masked Translation Priming Effects With Highly Proficient Simultaneous Bilinguals
2010
One essential issue for models of bilingual memory organization is to what degree the representation from one of the languages is shared with the other language. In this study, we examine whether there is a symmetrical translation priming effect with highly proficient, simultaneous bilinguals. We conducted a masked priming lexical decision experiment with cognate and noncognate translation equivalents. Results showed a significant masked translation priming effect for both cognates and noncognates, with a greater priming effect for cognates. Furthermore, the magnitude of the translation priming was similar in the two directions. Thus, highly fluent bilinguals do develop symmetrical between…
Differences Between Young and Old University Students on a Lexical Decision Task: Evidence Through an Ex-Gaussian Approach
2013
This work compared two common variants of a lexical decision task (LDT) through two different analysis procedures: first, the classical ANOVA method, and second, by fitting the data to an ex-Gaussian distribution function. Two groups of participants (old and young university students) had to perform, blocks of go/no-go and yes/no tasks. Reaction times and error rates were much lower in the go/no-go task than in the yes/no task. Changes in the ex-Gaussian parameter related to attention were found with word frequency but not with the type of LDT tasks. These findings suggest that word frequency shows an attentional cost that is independent of age.
Constituent priming effects: Evidence for preserved morphological processing in healthy old readers
2009
How elderly adults process morphologically complex words is still a matter of controversy. The present study explored whether compound word recognition is affected by ageing. A group of young adults and a group of older healthy adults were tested on a lexical decision task. Compound words were presented primed by their first constituent (book-BOOKSHOP), their second constituent (shop-BOOKSHOP), or by an unrelated word (house-BOOKSHOP). Results revealed that morphological processing is fully preserved in advanced age and that the magnitude of the constituent priming effect was similar for young and older adults.
Lexical Aspect and Motion Event Encoding in Homeric Greek: A Case Study - poster
2017
Lexical Aspect and Motion Event Encoding in Homeric Greek: A Case Study This paper aims to investigate the role that lexical aspect (Aktionsart) plays in motion event encoding in Homeric Greek. In particular, the role of telicity as an inherent semantic property of the verb has been recently re-evaluated within the verbal system of early Indo-European languages (Bartolotta 2016). On the basis of textual analysis of the Iliad and the Odyssey, I will argue how Homeric Greek motion verbs appear to be compatible with the entailment of the arrival of the Figure to the Ground according to their inherent telicity (see Bartolotta forthcoming). Specifically, I will focus on the Homeric verbs for ̔ru…
Lexical aspect and motion event encoding in homeric greek: a case study
2017
This paper aims to investigate the role that lexical aspect (Aktionsart) plays in motion event encoding in Homeric Greek. In particular, the role of telicity as an inherent semantic property of the verb has been recently re-evaluated within the verbal system of early Indo-European languages (Bartolotta 2016). According to Talmy (1985; 2000), a translational motion event consists of an object (Figure) that moves (Motion) through a path (Path) with respect to another reference object (Ground).On the basis of textual analysis of the Iliad and the Odyssey, I will argue how Homeric Greek motion verbs turn out to be compatible with the entailment of the arrival of the Figure to the Ground accordi…
