Word frequency plays a role in reduction processes: high-frequency words undergo more reduction than low-frequency words. Pretonic schwa reduction in Dutch is susceptible to frequency effects in this way, but the well-formedness of the cluster that remains after schwa deletion also plays a role. An experiment shows that cluster well-formedness and frequency effects in fact interact with each ot...

This study investigated the impact of Chinese ESL learners’ second language (L2) proficiency on English word recognition in a lexical decision task. The study focused on the interaction among one between-participant variable (L2 proficiency) and three within-participant variables (orthographic neighborhood density, word frequency, and words/nonwords). ANOVA and two-tailed t-test indicated that:...

Accuracy in identifying a perceptually degraded word (e.g., stake) can be either enhanced by recent exposure to the same stimulus or reduced by recent exposure to a similar stimulus (e.g., stare). In the present study, we explored the mechanisms underlying these benefits and costs by examining the performance of amnesic and control groups in a forced choice perceptual identification (FCPI) task...

BACKGROUND High-frequency deep brain stimulation (DBS) of the subthalamic nucleus (STN) improves motor functions in those with Parkinson disease but may worsen frontal functions such as verbal fluency (VF). In contrast, low-frequency DBS leads to deterioration of motor functions. It is not known whether low-frequency STN DBS also has an effect on frontal functions. OBJECTIVE To examine whethe...

Judgments of frequency for targets (old items) and foils (similar; dissimilar) steadily increase as the number of times a target is studied increases, but discrimination of targets from similar foils does not steadily improve, a phenomenon termed registration without learning (D. L. Hintzman & T. Curran, 1995; D. L. Hintzman, T. Curran, & B. Oppy, 1992). The present experiment explores this phe...

Low-frequency words, esp. words occurring only once in a text corpus, are very popular in text analysis. Also many lexicographers draw attention to such words. This paper lists a detailed statistical analysis of low-frequency words. The results provides important information for many practical applications, including lexicography and language modeling.

The statistical analysis of literary texts has yielded valuable results, not least when it has treated of the frequency patterns of very common words. But, whereas particular frequency patterns have usually been examined as discrete phenomena, it is possible to correlate the frequency profiles of all the very common words, to subject the resulting correlation matrix to eigen analysis, and to pr...

Abdollaahi, Ph.D. A perusal of the ministerial documents at the Iranian Ministry of Education during the past 100 years was undertaken in order to clarify how the general and professional qualifications required for the post of high school master have evolved over the c...

Zipf’s law states that the frequency of word tokens in a large corpus of natural language is inversely proportional to the rank. The law is investigated for two languages English and Mandarin and for ngram word phrases as well as for single words. The law for single words is shown to be valid only for high frequency words. However, when single word and n-gram phrases are combined together in on...
