The present study addresses three questions regarding age differences in working memory: (1) whether performance on complex span tasks decreases as a function of age at a faster rate than performance on simple span tasks; (2) whether spatial working memory decreases at a faster rate than verbal working memory; and (3) whether the structure of working memory abilities is different for different ...

Learners bring their unique individual perceptions, preferences, and abilities to a learning situation. The effect of individual differences on learning depends in part on how the instructional system accommodates for these differences. The current study examined the role of individual differences and structured navigation in hypertext learning. It was predicted that learning outcome would depe...

We review the concept of working memory as a short-duration system in which small amounts of information are simultaneously stored and manipulated in the service of accomplishing a task. We summarize the argument that syntactic processing in sentence comprehension requires such a storage and computati...

The genetic and environmental factor structures of intellectual abilities in 5-year-old Dutch twins were examined.

The genetic covariance structure displayed a two-common factor structure including specific factors to account for subtest residua...

In the present paper, we deal with diatheses in Czech from a lexicographic point of view. We propose a method of their description in the valency lexicon of Czech verbs VALLEX. We distinguish grammatical and semantic diatheses as two typologically different changes in verbal valency structure. In case of grammatical diatheses, these changes are regular enough to be described by formal syntactic...
