Positron emission tomography data (Madden, Langley, et al., 2002) were analyzed to investigate adult age differences in the relation between neural activation and the lexical (word frequency) and sublexical (word length) components of visual word identification. The differential influence of these components on reaction time (RT) for word/nonword discrimination (lexical decision) was generally similar for the two age groups, with word frequency accounting for a greater proportion of lexical decision RT variance relative to word length. The influence of word length on RT, however, was relatively greater for older adults. Activation in regions of the ventral occipito-temporal cortex was related to the RT changes associated with word frequency and length for older adults, but not for younger adults. Specifically, older adults' frequency effects were related to activation in both anterior (Brodmann's area [BA] 37) and posterior (BAs 17 and 18) regions of the occipito-temporal pathway, whereas word length effects were only associated with posterior activation (BA 17). We conclude that aging affects the neural mechanisms supporting word identification performance although behavioral measures of this ability are generally constant as a function of age.

Our current understanding of visual word identification is difficult to extend to text reading—both experiments and theories focus primarily, if not exclusively, on out-of-context individual words. Here, we try to fill this gap by studying cross-word semantic and morphological priming within sentences in a natural reading, eye tracking experiment. We find that words are skipped more when they are preceded in the sentence by semantically related primes. Also, cross-word semantic priming manifests itself in later (e.g., gaze duration), but not in earlier (e.g., first-of-many fixations) indexes of eye movement on the target words. We also find that semantic priming is not modulated by the morphological agreement between primes and targets; and that morphological agreement does not yield any priming per se. These results point to independent lexical-semantic and morphological processing during sentence reading, and suggest cross-word reset for the latter, but not for the former.

Morphologically complex words are processed through their constituent morphemes during visual word recognition. While this has been primarily established through the stem priming paradigm, the role of shared affixes is more controversial. Also, most evidence on affix priming comes from derivation, while inflectional priming remains largely unaddressed. Here we present two lexical decision, masked priming experiments filling this gap. Taking advantage of the rich inflectional pattern of Slovene, we assessed inflectional suffix priming (mestam–HALJAM), and compared it to the well-established stem priming effect (haljov–HALJAM): while the latter is solid as expected, the former seems to be weak to non–existing. Results further indicate that there is no interaction between sharing a stem and sharing an inflectional suffix—neither stem nor suffix priming is boosted when primes and targets also share the other morpheme. These data indicate an important difference between stems, derivational affixes and inflectional affixes, which we consider in the context of models of visual word identification and information theory.
