Purpose: Two types of orthographic knowledge were examined: i) knowledge of permissible letter combinations (general orthographic knowledge) and ii) knowledge of whole words (word-specific orthographic knowledge), to gain further insights into the relationship of general and word-specific orthographic knowledge with literacy skills. Method:…

The study examines whether the average performance of the population with dyslexia in a working memory measure can be inferred dimensionally from the characteristics of the typical population. Specifically, we focused on Associative Phonological Working Memory (APWM), an ability that we predicted being impaired in dyslexia due to the relationship…

The Cattell-Horn-Carroll (CHC) or three-stratum model of intelligence envisions human intelligence as a hierarchy. General intelligence (g) is situated at the top, under which are a group of broad intelligences such as verbal, visuospatial processing, and quantitative knowledge that pertain to more specific areas of reasoning. Some broad…

In this study, we investigated developmental aspects of eye movements during reading of three languages (English, German, and Finnish) that vary widely in their orthographic complexity and predictability. Grapheme-phoneme correspondence rules are rather complex in English and German but relatively simple in Finnish. Despite their differences in…

The education of gifted children is of considerable interest. The present study focused on the effect of enriched education on intellectually gifted children's attention. In the present study, 7-12-year-old children completed seven tests of attention (alertness, focused attention, divided attention, attentional switching, sustained attention,…

The study initiated a project exploring a contribution of creative perception to creative behavior. This study investigated the factors in creative self-perception contributing to creative potential. Creative potential was operationalized as divergent thinking and measured by the Abbreviated Torrance Test for Adults. Creative self-perception was…

The present study used a sample of Chinese rural-to-urban migrants in early adolescence to examine whether emotional awareness (EA) moderated the expected association between status-based discrimination and emotional-behavioral problems and whether patterns of associations differed across informants (self-report vs. teacher-report). A total of 169…

The term "intellectually gifted rural-to-urban migrant children" refers to intellectually gifted children who are in migration from rural to urban areas. We compared performances on seven attention tasks among intellectually gifted (n = 26) and average (n = 30) rural-to-urban migrant and intellectually gifted urban children (n = 31). Our…

Dyslexia in consistent orthographies like German is characterized by dysfluent reading, which is often assumed to result from failure to build up an orthographic lexicon and overreliance on decoding. However, earlier evidence indicates effects of lexical processing at least in some German dyslexic readers. We investigated variations in reading…

The secondary symptoms of individuals with dyslexia, such as high anxiety and low self-esteem, have aroused various debates not only in the educational, but also in the clinical context. Since pro and contra arguments are supported by a more or less equal number of empirical findings, no final conclusion could be drawn for this specific…

We investigated relative clause (RC) comprehension in 44 Russian-speaking children with typical language (TD) and developmental language disorder (DLD) (M age = 10;67, SD = 2.84) and 22 adults. Flexible word order and morphological case in Russian allowed us to isolate factors that are obscured in English, helping us to identify sources of…

The aim of the present study was to investigate the associations between elementary school children's mathematical achievement and their conservation abilities, visuospatial skills, and numerosity processing speed. We also assessed differences in these abilities between children with different types of learning problems. In Study 1 (N = 229), we…

Although children with specific reading disorder (RD) have often been compared to typically achieving children on various phonological processing tasks, to our knowledge no study so far has examined whether the structure of phonological processing applies to both groups of children alike. According to Wagner and Torgesen (1987), phonological…

As empirical studies have consistently shown, low achievement in mathematics at the secondary level can often be traced to deficits in the understanding of certain basic arithmetic concepts taught in primary school. The present intervention study in middle schools evaluated whether such learning deficits can be reduced effectively and whether the…

Executive function is best measured in loosely structured, multi-component tasks that reflect real-life demands. These tasks require participants to develop a strategy, keep a plan in mind and monitor time. Errors include ignoring stated goals ("goal neglect"), over-allocation of time to one task and violating rules. Teasing apart such…
