One of the difficulties in teaching Turkish, which is a phonetically rich language, to foreigners, is that similar sounds are often confused with each other. Since even a single punctuation mark is crucial for writing and reading Turkish letters (i-i, o-ö, u-ü, c-ç, g-g, s-s, etc.), students who use the Arabic alphabet have great difficulty…

The current study highlights the importance of inhibitory ability in facilitating performance in mathematics. To understand the role of inhibition in mathematical knowledge, this study tested 102 college students on a series of standardized complex math exercises. Inhibition tasks varied by task and stimuli (letters, numbers, and arrows). The…

Most orthographies contain both accented and non-accented vowels. But are they processed as variants of the same letter unit or as separate abstract units? Recent research in French has revealed that accented vowels seem to be processed as separate units. Here we examined whether this phenomenon is universal or language-specific. We chose Spanish…

This research pursued a fine-grained analysis of the acquisition of a procedural skill. In two experiments (n = 29 and n = 27), adults practiced 12 alphabet arithmetic problems (e.g., C + 3 = C D E F) in two sessions with 20 practice blocks in each. If learning reflected speed up of a counting algorithm, response time (RT) speed up should be…

Using Chinese characters, we investigated how stroke count and frequency of use influence attention and short-term memory (STM) encoding in Mainland Chinese speakers. To isolate specific components of attention we employed the Theory of Visual Attention (TVA), which allowed estimates of STM capacity, processing speed, and the threshold of visual…

It is well-established that allographs like the uppercase and lowercase forms of the Roman alphabet (e.g., a and A) map onto the same "abstract letter identity," orthographic representations that are independent of the visual form. Consistent with this, in the allograph match task ("Are 'a' and 'A' the same letter?"), priming…

This study examined whether different cognitive correlates are associated with spelling of different target types, such as phonologically consistent and inconsistent syllables, of Korean Hangul among 94 five-year-old first language (L1) Korean children and 41 foreign language (FL) learners who are Hong Kong Chinese college students. Korean…

Procedures for identifying the gifted often make use of tests of general intelligence, among other assessments. Robert J. Sternberg recently suggested that identification of the gifted should further involve assessment of what he refers to as adaptive intelligence--the ability to adapt to real-world environments. Such a conception of intelligence…

Three experiments using a spelling error detection task investigated the extent to which morphemes and pseudomorphemes affect word processing. We compared the processing of transparent compound words (e.g., doorbell), pseudocompound words (e.g., carpet), and matched control words (e.g., tomato). In half of the compound and pseudocompound words,…

It is generally agreed that first language (L1) morphological awareness, the ability to reflect upon, analyze and manipulate morphemes and morphological structure of words, can transfer and facilitate second language (L2) reading subskill acquisition. However, the facilitative role of L1 morphological awareness is unclear in the literature…

We examined whether the first letter advantage that has been reported in the Roman script disappears, or even reverses, depending on the characteristics of the orthography. We chose Thai because it has several "nonaligned" vowels that are written prior to the consonant but phonologically follow it in speech (e.g., ??? <e:fn> is…

Previous research has revealed conflicting results with regard to the role of the magnocellular visual system in reading and dyslexia. In order to investigate this further, the present study examined the relationship between performance on two magnocellular tasks (temporal gap detection and coherent motion), reading rate (oral and silent), and…

The purpose of this study was to examine different hypotheses in relation to RAN deficits in dyslexia. Thirty university students with dyslexia and 32 chronological-age controls were assessed on RAN Digits and Colors as well as on two versions of RAN Letters and Objects (one with five items repeated 16 times and one with 20 items repeated four…

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…

Transition effects in task-cuing experiments can be partitioned into task switching and cue repetition effects by using multiple cues per task. In the present study, the author shows that cue repetition effects can be partitioned into perceptual and conceptual priming effects. In 2 experiments, letters or numbers in their uppercase/lowercase or…
