Task  repetition  is  now  considered  as  an  important  task-based  implementation  variable  which can affect complexity, accuracy, and fluency of L2 speech. However, in order to move towards theorizing  the  role  of  task  repetition  in  second  language  acquisition,  it  is  necessary  that individual variables be taken into account. The present study aimed to investigate the way task r...

The neural response to stimulus repetition is not uniform across brain regions, stimulus modalities, or task contexts. For instance, it has been observed in many functional magnetic resonance imaging (fMRI) studies that sometimes stimulus repetition leads to a relative reduction in neural activity (repetition suppression), whereas in other cases repetition results in a relative increase in acti...

In this study, we investigated whether there is a repetition benefit in mental rotation that is independent of stimulus repetition (i.e., due to increased efficiency in postencoding processing). Three experiments were conducted, in which different conditions of stimulus repetition (different letters on consecutive trials in Experiment 1, letters of different orientations on consecutive trials i...

Repetition is avoided in countless human languages and at a variety of grammatical levels. In this dissertation I ask what it is that makes repetition so bad. I propose that at least three distinct biases against repetition exist. First, repetition of articulatory gestures is relatively difficult. This difficulty results in phonetic variation that may lead to categorical phonological avoidance....

Repetition normally enhances memory. While in some cases the benefit of added repetition may be incremental, few would expect that massed repetition could actually reverse the benefits of brief repetition. Here we report two experiments that document a clear example of a paradoxical effect of massed repetition. Subjects first repeated words (e.g., "sheep") aloud one at a time for 0, 5, 10, 20, ...

This study examined how aging affects the spatial patterns of repetition effects associated with perceptual priming of unfamiliar visual objects. Healthy young (n = 14) and elderly adults (n = 13) viewed four repetitions of structurally possible and impossible figures while being scanned with blood oxygenation level-dependent functional magnetic resonance imaging. Although explicit recognition ...

Although it has been well documented that the spatial inhibitory effect induced by repetition of location (i.e., spatial inhibition of return, or IOR) occurs cross-modally, we do not yet know whether nonspatial (e.g., color-based) repetition-induced inhibition occurs in a cross-modal fashion as well. In the present study, a novel cross-modal paradigm with regard to color-based repetition was ad...

OBJECTIVES To understand how commonly diminution of verbal repetition was a goal of treatment in patients with Alzheimer disease (AD), how commonly that goal was achieved, whether goal attainment might be attributable to galantamine treatment, and whether change in verbal repetition is a marker of the overall treatment response. METHODS This is a secondary analysis of the Video-Imaging Synthe...

Activation decay functions were examined in two different tasks: lexical decision and word recognition. Activation (amount of facilitation) was measured both for item repetition and for priming between newly learned associates. Results indicate that there are at least three different components of activation: a short-term component that decays with one or two intervening items and that appears ...
