Sun, Meng; Zhang, Xiaorong; Wang, Jiangmeng; Liu, Hailan; Zhang, Qin; Cui, Lixia – SAGE Open, 2020
This study explored whether the color of letters could influence letter discrimination task performances and whether this effect of color could be modulated by processing level (global vs. local) and attention level of color (color-attended vs. color-unattended). We used the Navon letters in red, green, or white as stimuli at a relatively small…

Kim, Young-Suk Grace; Petscher, Yaacov; Treiman, Rebecca; Kelcey, Benjamin – Grantee Submission, 2020
To expand our understanding of script-general and script-specific principles in the learning of letter names, we examined how three characteristics of alphabet letters -- their frequency in printed materials, order in the alphabet, and visual similarity to other letters -- relate to children's letter-name knowledge in four languages with three…

Lochy, Aliette; Schiltz, Christine – Child Development, 2019
The emergence of visual cortex specialization for culturally acquired characters like letters and digits, both arbitrary shapes related to specific cognitive domains, is yet unclear. Here, 20 young children (6.12 years old) were tested with a frequency-tagging paradigm coupled with electroencephalogram recordings to assess discrimination responses…

Jordan, Timothy R.; McGowan, Victoria A.; Kurtev, Stoyan; Paterson, Kevin B. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2016
When reading from left to right, useful information acquired during each fixational pause is widely assumed to extend 14 to 15 characters to the right of fixation but just 3 to 4 characters to the left, and certainly no further than the beginning of the fixated word. However, this leftward extent is strikingly small and seems inconsistent with…

Chetail, Fabienne; Drabs, Virginie; Content, Alain – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2014
According to a recent hypothesis, the CV pattern (i.e., the arrangement of consonant and vowel letters) constrains the mental representation of letter strings, with each vowel or vowel cluster being the core of a unit. Six experiments with the same/different task were conducted to test whether this structure is extracted prelexically. In the…

Hobbs, L. Jon; Overby, Melanie – Grantee Submission, 2017
UPSTART is a federally funded i3 validation project that uses a computer-based program to develop the school readiness skills of preschool children in rural Utah. Researchers used a randomized control trial design to evaluate the impact of the program in advancing children's early literacy skills. Preschoolers in the experimental group were…

Zhaoping, Li; Frith, Uta – Journal of Experimental Psychology: Human Perception and Performance, 2011
It is harder to find the letter "N" among its mirror reversals than vice versa, an inconvenient finding for bottom-up saliency accounts based on primary visual cortex (V1) mechanisms. However, in line with this account, we found that in dense search arrays, gaze first landed on either target equally fast. Remarkably, after first landing,…

Guzman-Martinez, Emmanuel; Grabowecky, Marcia; Palafox, German; Suzuki, Satoru – Journal of Experimental Psychology: Human Perception and Performance, 2011
Visual spatial attention can be exogenously captured by a salient stimulus or can be endogenously allocated by voluntary effort. Whether these two attention modes serve distinctive functions is debated, but for processing of single targets the literature suggests superiority of exogenous attention (it is faster acting and serves more functions).…

Ratcliff, Roger; Smith, Philip L. – Journal of Experimental Psychology: General, 2010
The authors report 9 new experiments and reanalyze 3 published experiments that investigate factors affecting the time course of perceptual processing and its effects on subsequent decision making. Stimuli in letter-discrimination and brightness-discrimination tasks were degraded with static and dynamic noise. The onset and the time course of…

Tolchinsky, Liliana; Levin, Iris; Aram, Dorit; McBride-Chang, Catherine – Reading and Writing: An Interdisciplinary Journal, 2012
Preschoolers' metalinguistic and visual capabilities may be associated with the writing system of their culture. We examined patterns of performance in phonological awareness, naming of letters, morphological awareness, and visual-spatial relations, in 5-year-old native speakers of Spanish (n = 43), Hebrew (n = 40), and Cantonese (n = 63) and the…

Ziegler, Johannes C.; Pech-Georgel, Catherine; Dufau, Stephane; Grainger, Jonathan – Developmental Science, 2010
Visual-attentional theories of dyslexia predict deficits for dyslexic children not only for the perception of letter strings but also for non-alphanumeric symbol strings. This prediction was tested in a two-alternative forced-choice paradigm with letters, digits, and symbols. Children with dyslexia showed significant deficits for letter and digit…

Kolinsky, Regine; Verhaeghe, Arlette; Fernandes, Tania; Mengarda, Elias Jose; Grimm-Cabral, Loni; Morais, Jose – Journal of Experimental Psychology: General, 2011
To examine whether enantiomorphy (i.e., the ability to discriminate lateral mirror images) is influenced by the acquisition of a written system that incorporates mirrored letters (e.g., b and d), unschooled illiterate adults were compared with people reading the Latin alphabet, namely, both schooled literate adults and unschooled adults…

Woodrome, Stacey E.; Johnson, Kathy E. – Reading and Writing: An Interdisciplinary Journal, 2009
Two studies were conducted to evaluate the extent to which visual discrimination (VisD) skills play a role in developing letter identification abilities, which are essential in learning to read. Results from a correlational analysis of 73 4- and 5-year-olds revealed a significant association between VisD and letter identification abilities, which…

Samuels, S. Jay – 1970
A laboratory and a classroom study were conducted to determine if verbal association learning would be facilitated by visual discrimination training. Kindergarten children who could not recognize the letters used were the subjects for both studies. In the laboratory study, 90 subjects were randomly assigned to the experimental group (E) which got…
