Understanding reading is a central issue for psychology, with major societal implications. Over the past five decades, a simple letter-detection task has been used as a window on the psycholinguistic processes involved in reading. When readers are asked to read a text for comprehension while marking with a pencil all instances of a target letter, they miss some of the letters in a systematic way known as the missing-letter effect. In the current article, we review evidence from studies that have emphasized neuroimaging, eye movement, rapid serial visual presentation, and auditory passages. As we review, the missing-letter effect captures a wide variety of cognitive processes, including lexical activation, attention, and extraction of phrase structure. To account for the large set of findings generated by studies of the missing-letter effect, we advanced an attentional-disengagement model that is rooted in how attention is allocated to and disengaged from lexical items during reading, which we have recently shown applies equally to listening.

Multiple Languages

Multilink developed by Dijkstra et al. (2018) is a computational model of monolingual and bilingual lexical access in comprehension and production. The non-selective activation of a bilingual's two languages is handled in the model by assuming that bilinguals have an integrated lexicon and that orthographic overlap between the input and the lexical representation drives lexical activation. Hence, an orthographic unit such as the letter T may activate words from multiple languages that contain the letter, resulting in simultaneous activation of multiple languages. This basic mechanism for explaining non-selective activation is similar between Multilink and its predecessors BIA and BIA+.

Lexical Activation

The chapter starts with a definition and models of mental dictionary. It then builds on the bilingual lexical activation models and goes on to discuss formulaic language (collocations in particular). After explaining the basics of formulaic language processing, the author attempts to address the issue of lexical and collocational priming theory by Hoey, which has its roots in cognitive linguistics and usage-based language models. Last but not least, some suggestions for future research are provided in an attempt to address the needs of the lexical research literature in the Turkish setting.

Spoken word recognition models incorporate the temporal unfolding of word information by assuming that positional match constrains lexical activation. Recent findings challenge the linearity constraint. In the visual world paradigm, Toscano, Anderson, and McMurray observed that listeners preferentially viewed a picture of a target word’s anadrome competitor (e.g., competitor bus for target sub) compared with phonologically unrelated distractors (e.g., well) or competitors sharing an overlapping vowel (e.g., sun). Toscano et al. concluded that spoken word recognition relies on coarse grain spectral similarity for mapping spoken input to a lexical representation. Our experiments aimed to replicate the anadrome effect and to test the coarse grain similarity account using competitors without vowel position overlap (e.g., competitor leaf for target flea). The results confirmed the original effect: anadrome competitor fixation curves diverged from unrelated distractors approximately 275 ms after the onset of the target word. In contrast, the no vowel position overlap competitor did not show an increase in fixations compared with the unrelated distractors. The contrasting results for the anadrome and no vowel position overlap items are discussed in terms of theoretical implications of sequential match versus coarse grain similarity accounts of spoken word recognition. We also discuss design issues (repetition of stimulus materials and display parameters) concerning the use of the visual world paradigm in making inferences about online spoken word recognition.

We examined how linguistic context influences the nature of bilingual lexical activation. We hypothesized that in single-word context, form-related words would receive the strongest activation while, in sentence context, semantically related words would receive the strongest activation. Spanish–English bilinguals performed a semantic verification task on English target words preceded by a prime. On critical trials, the prime and target words were paired based either on a form-mediated relationship through the native language (L1), [e.g., bark (barco): BOAT] (Experiment 1) or on a semantically-mediated relationship [e.g., boat (barco): BARK] (Experiment 2). The prime word was presented either in isolation or after a sentence context. In Experiment 1 interference was observed in the single word condition only. In Experiment 2 interference was observed in both single-word and sentence contexts. The findings demonstrate that the context in which words are embedded has an impact on the type of lexical competitors that become active.
