We show that the minimal proportion of one letter in an n-th power-free binary word is asymptotically 1=n. We also consider a generalization of n-th power-free words deened through the notion of exponent: a word is x-th power-free for a real x, if it does not contain subwords of exponent x or more. We study the minimal proportion of one letter in an x-th power-free binary word as a function of ...

The current study explored statistical learning processes in the acquisition of orthographic knowledge in school-aged children and skilled adults. Learning of novel graphotactic constraints on the position and context of letter distributions was induced by means of a two-phase learning task adapted from Onishi, Chambers, and Fisher (Cognition, 83 (2002) B13-B23). Following incidental exposure t...

Incidental recognition memory for faces previously exposed as task-irrelevant distractors was assessed as a function of the attentional load of an unrelated task performed on superimposed letter strings at exposure. In Experiment 1, subjects were told to ignore the faces and either to judge the color of the letters (low load) or to search for an angular target letter among other angular letters...

This paper reports the results of a content analysis of comment letters submitted to the Financial Accounting Standards Board in response to the Board’s Comprehensive Income Reporting Exposure Draft (FASB, 1996). Although comment letters are an integral component of the FASB’s standard setting process, little is known about their content and the types of arguments made by letter writers. In thi...

We review the recent progress in the investigation of powerfree words, with particular emphasis on binary cubefree and ternary squarefree words. Besides various bounds on the entropy, we provide bounds on letter frequencies and consider their empirical distribution obtained by an enumeration of binary cubefree words up to length 80.
