Abstract Writing is a recently acquired skill to human behavioral repertoire, essential in industrialized societies. In the clinic, writing impairment evident one-third of stroke patients. This study aimed find out cognitive features that contribute patients two different systems (logographic and phonological). Cognitive profiles were assessed using Birmingham Screen cohorts, China (244 patient...

Native English speakers with no knowledge of Chinese were trained on 60 Chinese characters according to one of three mapping conditions: orthography to pronunciation and meaning (P + M), orthography to pronunciation (P), and orthography to meaning (M). Following the training, fMRI scans taken during passive viewing of Chinese characters showed activation in brain regions that partially overlap ...

Graphemes are commonly defined as the written representation of phonemes. For example, the word 'BREAD' is composed of the four phonemes /b/, /r/, /e/ and /d/, and consequently, of the four graphemes 'B', 'R', 'EA', and 'D'. Graphemes can thus be considered the minimal 'functional bridges' in the mapping between orthography and phonology. In the present study, we investigated the hypothesis tha...

L earning to read visual words aloud requires a novel integration of two distinct neurocognitive systems: a visual system that allows one to recognize a visual word from a crowd of letter features and a phonological language system that allows one to recognize and produce spoken words from a crowd of phonetic features (1). Integrating these two systems through the alphabetic principle bestows s...

We present the construction of a continuous time stochastic process which has moments that satisfy an exact scaling relation, including odd order moments. It is based on a natural extension of the MRW construction described in [3]. This allows us to propose a continuous time model for the price of a financial asset that reflects most major stylized facts observed on real data, including asymmet...

A study investigating the way in which people solve alphabetic analogical reasoning tasks (cf Copycat; Hofstadter & Mitchell, 1995), revealed that participants tend to use the same basic strategy, which was modelled in the cognitive architecture ACT-R. Performance evaluations indicate an average goodness of fit of 66.75% and a 100% goodness of fit on a subset of problems for which participants ...

An alphabetic binary tree formulation applies to problems in which an outcome needs to be determined via alphabetically ordered search prior to the termination of some window of opportunity. Rather than finding a decision tree minimizing ∑n i=1w(i)l(i), this variant involves minimizing loga ∑n i=1 w(i)a l(i) for a given a ∈ (0, 1). This note introduces a dynamic programming algorithm that finds...
