Book Description
In several experiments, masked repetition priming in the lexical decision task was greater when prime validity, defined as the proportion of repetition versus unrelated primes, was high (.8 vs. .2), even though primes were displayed for only 45 or 60 ms. A similar effect was also found with masked semantic primes. Prime validity effects are not predicted on a lexical entry-opening account of masked priming nor are they consistent with the use of prime validity effects as a marker for the consciously controlled use of primes. Instead, it is argued that episodic traces are formed even for masked primes, are available as a resource that can aid word identification, and are generally more likely to be recruited when their validity is high. However, prime validity effects did not obtain when targets varied markedly from trial to trial in how easy they were to process. Here, it appears that trial-to-trial discrepancies made the lexical decision task more difficult, causing an increase in prime recruitment, at least when prime validity was low. Consistent with this claim, prime validity effects emerged when these trial-to-trial discrepancies were minimized.

Book Description
Masked priming has a short and somewhat controversial history. When used as a tool to study whether semantic processing can occur in the absence of conscious awareness, considerable debate followed, mainly about whether masked priming truly tapped unconscious processes. For research into other components of visual word processing, however - in particular, orthographic, phonological, and morphological - a general consensus about the evidence provided by masked priming results has emerged. This book contains thirteen original chapters in which these three components of visual word processing are examined using the masked priming procedure. The chapters showcase the advantages of masked priming as an alternative to more standard methods of studying language processing that require comparisons of matched items. Based on a recent conference, this book offers up-to-date research findings, and would be valuable to researchers and students of word recognition, psycholinguistics, or reading.

Book Description
Correct word identification and processing is a prerequisite for accurate reading, and decades of psycholinguistic and neuroscientific research have shown that the magical moments of visual word recognition are short-lived and markedly fast. The time window in which a given letter string passes from being a mere sequence of printed curves and strokes to acquiring the word status takes around one third of a second. In a few hundred milliseconds, a skilled reader recognizes an isolated word and carries out a number of underlying processes, such as the encoding of letter position and letter identity, and lexico-semantic information retrieval. However, the precise manner (and order) in which these processes occur (or co-occur) is a matter of contention subject to empirical research. There’s no agreement regarding the precise timing of some of the essential processes that guide visual word processing, such as precise letter identification, letter position assignment or sub-word unit processing (bigrams, trigrams, syllables, morphemes), among others. Which is the sequence of processes that lead to lexical access? How do these and other processes interact with each other during the early moments of word processing? Do these processes occur in a serial fashion or do they take place in parallel? Are these processes subject to mutual interaction principles? Is feedback allowed for within the earliest stages of word identification? And ultimately, when does the reader’s brain effectively identify a given word? A vast number of questions remain open, and this Research Topic will cover some of them, giving the readership the opportunity to understand how the scientific community faces the problem of modeling the early stages of word identification according to the latest neuroscientific findings. The present Research Topic aimed to combine recent experimental evidence on early word processing from different techniques together with comprehensive reviews of the current work directions, in order to create a landmark forum in which experts in the field defined the state of the art and future directions. We were willing to receive submissions of empirical as well as theoretical and review articles based on different computational and neuroscience-oriented methodologies. We especially encouraged researchers primarily using electrophysiological or magnetoencephalographic techniques as well as eye-tracking to participate, given that these techniques provide us with the opportunity to uncover the mysteries of lexical access allowing for a fine-grained time-course analysis. The main focus of interest concerned the processes that are held within the initial 250-300 milliseconds after word presentation, covering areas that link basic visuo-attentional systems with linguistic mechanisms.

Book Description
There are now extensive behavioral and neuropsychological evidence to indicate that semantic information of a word can be activated without conscious awareness. However, semantic activation alone may not be sufficient for observing semantic priming effects in masked lexical decision task. In the following study, two tasks were used: lexical decision and semantic categorization. Conscious awareness of the prime was systematically manipulated by varying the duration of the prime and by varying the placement of the mask in the prime-target presentation sequence. Priming effects were observed in the semantic categorization task at prime durations of 42 milliseconds but no semantic priming was observed for the same prime duration in the lexical decision task. However, semantic priming effects began to emerge in lexical decision at the longer prime durations (55 & 69 ms) and under the least effective prime-mask presentation sequences. It is proposed that semantic activation alone is not sufficient for semantic priming effects in the lexical decision task but that central executive involvement is necessary, if only at the lowest level, for facilitatory effects to be observed. Furthermore, no such central executive involvement appears to be required for the semantic categorization task. The priming effects obtained in this task is interpreted in terms of a"decision priming"effect.

Book Description
The other volume looks at the processes of recognizing a word visually and the performance of word-based tasks. Here the focus widens, and psychologists consider such recognition as a link to semantics and concepts, cognitive individual differences, reading prose, and learning to read. Their topics include meaning-based influences on visual word recognition, eye movements and word recognition during reading, bilingual visual word recognition in sentence context, the effect of lexical quality on individual differences in skilled visual word recognition and reading, and how visual word recognition is affected by developmental dyslexia.
