A ubiquitous characteristic of human cortical networks is their tendency to rapidly change their response properties upon repetition. While this phenomenon has been amply documented using simple sensory-motor tasks, it is still unclear to what extent brain activations change on a short time scale when we are engaged in high level, complex tasks. Here, we examined this question using three types...

In mathematics, the task of interpolating observed data has a long history. Recently, this task has gained even more attention, also from a statistical point of view, as there are many data situations, where either there is no random error (e.g. computer experiments) or the underlying data generating process is very precise such that a repetition will yield the same numerical result. Here we pr...

Time redundancy is a fault tolerance technique in which a task -either computation or communication -is performed multiple times on the same hardware. This technique is cheaper than other fault tolerance solutions that require some form of hardware redundancy, because it does not require replicated hardware. However, fault coverage may be lower with time redundancy as it only captures certain c...

The amnesic patient E.P. has demonstrated normal levels of repetition priming and at-chance recognition performance (S. B. Hamann & L. R. Squire, 1997), suggesting that the sense of familiarity used to make a recognition memory judgment is not based on the same mechanism responsible for repetition priming. However, the recognition tests previously used may have discouraged the use of familiarit...

UNLABELLED When learning a new language, we build brain networks to process and represent the acquired words and syntax and integrate these with existing language representations. It is an open question whether the same or different neural mechanisms are involved in learning and processing a novel language compared with the native language(s). Here we investigated the neural repetition effects ...

Compared to words that are new to a discourse, repeated words are produced with reduced acoustic prominence. Although these effects are often attributed to priming in the production system, the locus of the effect within the production system remains unresolved because, in natural speech, repetition often involves repetition of referents and lexical items simultaneously. Therefore, repetition r...

A growing body of research has documented effects of phonotactic probability on young children's nonword repetition. This study extends this research in 2 ways. First, it compares nonword repetitions by 40 young children with phonological disorders with those by 40 same-age peers with typical phonological development on a nonword repetition task in which the frequency of embedded diphone sequen...

Previous research has shown that when the targets of successive visual searches have features in common, response times are shorter. However, the nature of the representation underlying this priming and how priming is affected by the task remain uncertain. In four experiments, subjects searched for an odd-sized target and reported its orientation. The color of the items was irrelevant to the ta...

Recent event-related potential research has reported a N200 response or a negative deflection peaking around 200 ms following the visual presentation of two-character Chinese words. This N200 shows amplitude enhancement upon immediate repetition and there has been preliminary evidence that it reflects orthographic processing but not semantic processing. The present study tested whether this N20...

Three experiments investigated the cognitive mechanisms underlying the restart cost and mixing cost in task switching. To this aim, the predictability of task order was varied (unpredictable in Experiment 1 and predictable in Experiments 2 and 3) across experiments, which employed a multiple-trial paradigm. Verbal cues for color and shape matching tasks were presented before a run of four trial...
