Repetition enhancement and perceptual processing of visual word form
The current study investigated the cerebral basis of word perceptual repetition priming with fMRI during a letter detection task that manipulated the familiarity of perceptual word form and the number of repetitions. Some neuroimaging studies have reported increases, instead of decreases, in brain activations (called "repetition enhancement") associated with repetition priming of unfamiliar sti...
متن کاملThe suppression of repetition enhancement: a review of fMRI studies.
Repetition suppression in fMRI studies is generally thought to underlie behavioural facilitation effects (i.e., priming) and it is often used to identify the neuronal representations associated with a stimulus. However, this pays little heed to the large number of repetition enhancement effects observed under similar conditions. In this review, we identify several cognitive variables biasing re...
متن کاملRepetition probability does not affect fMRI repetition suppression for objects.
Previously several functional magnetic resonance imaging (fMRI) studies point toward the role of perceptual expectations in determining adaptation or repetition suppression (RS) in humans. These studies showed that the probability of repetitions of faces within a block influences the magnitude of adaptation in face-related areas of the human brain (Summerfield et al., 2008). However, a current ...
متن کاملMedial temporal lobe-dependent repetition suppression and enhancement due to implicit vs. explicit processing of individual repeated search displays
Using visual search, functional magnetic resonance imaging (fMRI) and patient studies have demonstrated that medial temporal lobe (MTL) structures differentiate repeated from novel displays-even when observers are unaware of display repetitions. This suggests a role for MTL in both explicit and, importantly, implicit learning of repeated sensory information (Greene et al., 2007). However, recen...
متن کاملEnumeration Schemes for Words Avoiding Patterns with Repeated Letters
In this paper, we discuss the enumeration of words avoiding patterns with repeated letters. More specifically, we find recurrences (i.e. enumeration schemes) counting words avoiding any pattern of length 3 and words avoiding any monotone pattern.
