The aim of this study was to establish cognitive profiles of dyslexic adults on tests developed within the three main theories of developmental dyslexia: phonological, visual magnocellular and cerebellar and to investigate which theory can account for these profiles. The sample consisted of 15 Polish university students or alumni with a formal diagnosis of(More)
Historically, the concepts of field-independence, closure flexibility, and weak central coherence have been used to denote a locally, rather globally, dominated perceptual style. To date, there has been little attempt to clarify the relationship between these constructs, or to examine the convergent validity of the various tasks purported to measure them.(More)
57 Polish-speaking children aged from 2;4, to 4;8 and 16 adult controls participated in a nonce-word inflection experiment testing their ability to use the genitive, dative and accusative inflections productively. Results show that this ability develops early: the majority of two-year-olds were already productive with all inflections apart from dative(More)
We report a dissociation between higher order mathematical ability and language in the case of a man (SO) with severe aphasia. Despite severely impaired abilities in the language domain and difficulties with processing both phonological and orthographic number words, he was able to judge the equivalence of and to transform and simplify mathematical(More)
This paper investigates whether people with Williams syndrome (WS) have prosodic impairments affecting their expression and comprehension of four main uses of intonation. Two adolescent males with WS were assessed using the PEPS-C battery, which considers prosodic abilities within a psycholinguistic framework, assessing prosodic form and function in both(More)
We explored the role of phonological representations of number words in exact calculation. The reaction times and accuracy of responses in multidigit addition problems were compared across three groups of participants (young healthy, older healthy, and 3 patients with severe aphasia) and two types of addition problems: phonologically long in English(More)
The development of phonological awareness (PA), the ability to reflect on the sound structure of words independent of their meaning, has been extensively explored in English-speaking children. However, this is not the case for other languages. The aim of this study was to develop a comprehensive PA test battery for German-speaking preschool children,(More)
We describe a lexical database consisting of morphologically and phonetically tagged words that occur in the texts primarily used for language arts instruction in the Czech Republic, Poland and Slovakia in the initial period of primary education (up to grade 4 or 5). The database aims to parallel the contents and usage of the British English Children’s(More)
The aim of this work was to study the effects of valence and age on visual image recognition memory. The International Affective Picture System (IAPS) battery was used, and response time data were analyzed using analysis of variance, as well as an ex-Gaussian fit method. Older participants were slower and more variable in their reaction times. Response(More)
Two competing approaches to the analysis of the phonological structure of Mandarin syllables have been put forward. The first and more traditional approach is that a syllable can be segmented into initial consonant, medial glide, nucleus plus coda and tone. The second approach does not distinguish the non-compulsory medial glide as an independent element.(More)
