objective : the major objective of this study was to determine the means and 95% confidence interval of normal 6 years old children's motor-verbal skills. based on the results of this study we could develop a measure to diagnose abnormal motor skills. in addition, in this follow-up study, we compared the first-graders' motor-verbal skills to their own skills one year earlier. method: ...

It has been suggested that repeated stimuli have shorter subjective duration than novel items, perhaps because of a reduction in the neural response to repeated presentations of the same object. Five experiments investigated the effects of repetition on time perception and found further evidence that immediate repetition reduces apparent duration, consistent with the idea that subjective durati...

Differences in vocabulary size among children can be explained in part by differences in parents' language input, but features of caregivers' input can be more or less beneficial depending on children's language abilities. The current study focused on a specific feature of infant-directed speech: parents' repetition of words across utterances. Although previous work with infants showed a positi...

Repetition of any number of cognitive processes can facilitate subsequent performance (i.e., repetition priming). In this study, we explored several candidate mechanisms that could account for repetition priming on a word generation task. In Experiment 1, we examined whether repetition of semantic processing is necessary for priming on this task. In Experiment 2, we examined whether repetition ...

Corneal ultrastructural changes induced by an argon fluoride excimer laser using different parameters were investigated. Twenty-eight rabbit corneas were ablated at light doses per pulse and repetition rates ranging from 25-800 mJ/cm2 and 1-100 Hz, respectively, at four different total light doses (25-150 J/cm2). Transmission electron microscopy showed that corneal ablations done at subthreshol...

We prove an impossibility result for a randomness-efficient parallel repetition. Our result is motivated by an early result of Feige and Kilian (STOC’95), who proved an impossibility result for randomness-efficient parallel repetition for two prover games with small degree, i.e., when each prover has only few possibilities for the question of the other prover. In recent years, there have been i...

This quasi-experimental study aimed to investigate the effect of task repetition under four conditions on the three dimensions of oral production (accuracy, complexity and fluency) and grammatical knowledge gain of learners of English as a Foreign Language (EFL). 40 young learners of English as a Foreign Language in four classes were randomly assigned into one of the following groups: repetitio...

Introduction: Although chronic ankle instability (CAI) is a condition characterized by numerous ankle sprains and the recurring sensation of ankle instability, which result in activity limitations and participation restrictions. Repetition based balance training protocols on type of the balance exercises may improve the deficits often associated with CAI. The objective of this study was to dete...

Detection of regularities (e.g., symmetry, repetition) can be used to investigate object and shape perception. Symmetry and nearby lines may both signal that one object is present, so moving lines apart may disrupt symmetry detection, while repetition may signal that multiple objects are present. Participants discriminated symmetrical/irregular and repeated/irregular pairs of lines. For vision,...

A previous time-series study showed that rapidly repeating a single-word version of a negative self-referential thought reduced the discomfort and the believability associated with that thought. The present parametric study examined whether durations of word repetition were differentially effective in altering the discomfort and believability of negative self-referential thought. In two studies...
