Alphabetic Language

In Indo-European languages, letter position coding is particularly noisy in middle positions (e.g., judge and jugde look very similar), but not in the initial letter position (e.g., judge vs. ujdge). Here we focus on a language (Thai) which, potentially, may be more flexible with respect to letter position coding than Indo-European languages: (i) Thai is an alphabetic language which is written without spaces between words (i.e., there is a degree of ambiguity in relation to which word a given letter belongs to) and (ii) some of the vowels are misaligned (e.g., [Formula: see text]/ε:bn/ is pronounced as /bε:n/), whereas others are not (e.g., [Formula: see text]/a:p/ is pronounced as /a:p/). We conducted a masked priming lexical decision experiment with 3–4 letter Thai words (with vs. without an initial misaligned vowel) in which the prime was: (i) identical to the target, (ii) a nonword generated by transposing the two initial letters of the target, or (iii) a replacement-letter control nonword. Results showed a significant masked transposed-letter priming effect in the initial letter positions, which was similar in size for words with and without an initial misaligned vowel. These findings reflect that: (i) letter position coding in Thai is very flexible and (ii) the nature of the obtained priming effects is orthographic rather than phonological.

Position Coding

We conducted three eye movement experiments to investigate the mechanism for coding letter positions in a person’s second language during sentence reading; we also examined the role of morphology in this process with more rigorous manipulation. Given that readers not only obtain information from currently fixated words (i.e., the foveal area) but also from upcoming words (i.e., the parafoveal area) to guide their reading, we examined both when the targets were fixated (Exp. 1) and when the targets were seen parafoveally (Exp. 2 and Exp. 3). First, we found the classic transposed letter (TL) effect in Exp. 1, but not in Exp. 2 or Exp. 3. This implies that flexible letter position coding exists during sentence reading. However, this was limited to words located in the foveal area, suggesting that L2 readers whose L2 proficiency is not as high as skilled native readers are not able to extract and utilize the parafoveal letter identity and position information of a word, whether the word length is long (Exp. 2) or short (Exp. 3). Second, we found morphological information to influence the magnitude of the TL effect in Exp. 1. These results provide new eye movement evidence for the flexibility of L2 letter position coding during sentence reading, as well as the interactions between the different internal representations of words in this process. Altogether, this is helpful for understanding L2 sentence reading and visual word recognition. Thus, future L2 reading frameworks should integrate word recognition and eye movement control models.

Abstract. Three masked priming experiments investigated the effects of target word length and number of inserted letters on superset priming, where irrelevant letters are added to targets to form prime stimuli (e.g., tanble-table). Effects of one, two, three, and four-letter insertions were measured relative to an unrelated prime condition, the identity prime condition, and a condition where the order of letters of the superset primes was reversed. Superset primes facilitated performance compared with unrelated primes and reversed primes, and the overall pattern showed a small cost of letter insertion that was independent of target word length and that increased linearly as a function of the number of inserted letters. A meta-analysis incorporating data from the present study and two other studies investigating superset priming, showed an average estimated processing cost of 11 ms per letter insertion. Models of letter position coding are examined in the light of this result.

AbstractWe agree with Frost that flexible letter-position coding is unlikely to be a universal property of word recognition across different orthographies. We argue that it is particularly unlikely in morphologically rich languages like Finnish. We also argue that dual-route models are not overly flexible and that they are well equipped to adapt to the linguistic environment at hand.
