This paper introduces a revised model for the development of basic computation skills. The model draws on four key phases, which have proven to be important for the development of calculation strategies and stresses the use of gestures and the verbalisation of concrete and mental images. This seems to be of crucial importance for children with…

Latent growth models were applied to data on multitrial verbal and spatial learning tasks from two independent studies. Although significant individual differences in both initial level of performance and subsequent learning were found in both tasks, age differences were found only in mean initial level, and not in mean learning. In neither task…

Based on the theory that the human left brain hemisphere processes verbal-sequential data and that the right hemisphere processes visual-spatial data, this article presents a teaching strategy for stimulating both hemispheres. It also describes the study that contributed to this strategy. (DS)

A variable time delay naming latency paradigm was used to investigate the processing of noun-verb lexical ambiguities (e.g., "watch") in syntactic contexts that biased either the noun or the verb reading. Results support a two-stage model in which all reading of ambiguous words are initially accessed, followed by suppression of…

Two experiments investigated the relationship of verification to the answering of yes-no questions. Subjects verified simple statements or answered simple questions. Various proposals concerning the relative difficulty of answering questions and verifying statements were considered, and a model was proposed. (SW)

Five experiments were conducted that illustrate microprocesses of discourse comprehension related to foregrounding. An intermediate case in which prior memories exist but must be reinstated to active memory was studied in detail. (SW)

A phoneme confusion matrix consisting of 1,620 spontaneous speech errors was analyzed. It is shown that there is no tendency for linguistically unmarked consonants to replace marked consonants and that sound segment errors almost always involve the movement of unitary segments and not the movement of component distinctive features. (SW)

Used a variance-partitioning procedure to identify age-related and age-invariant components of verbal and spatial memory span in 6- to 12-year olds. Concluded that verbal and spatial short-term memory appear to rely on similar processes when serial recall is required and that development in span is closely tied to increases in processing speed.…

The assessment profiles of 30 school-age children identified with either nonverbal or language-based learning disabilities were examined using a self-organizing systems paradigm. Results suggest that overflow into areas not typically associated with each disability subtype may occur. Concerns regarding ways of determining discrepancy for…

Three treatments based on the model of memory proposed by R.M. Gagne and R.T. White were compared in their effects on eighth- and ninth-graders' learning and retention of geographical facts and skills. The first treatment had an active excursion, the second had a passive excursion, and the third had no excursion. (Author/PN)

The main objective of the Goteborg Project on Non-Verbatim Learning was to arrive at a commensurable description of the process and outcome of non-verbatim learning, also referred to as meaningful verbal learning. Such a description was thought to be a necessary presupposition for any explanatory models both in experiments on learning and in the…
