Soltani, Amanallah; Mirhosseini, Sanaz – International Journal of Disability, Development and Education, 2020
General cognitive and specific number abilities that underlay arithmetic performance have been heavily investigated among typically developing students; however, the inquiry has rarely been applied to students with mild intellectual disability (MID). We examined whether domain-general cognitive abilities (i.e. working memory, processing speed, and…

Ashworth, Anna; Hill, Catherine M.; Karmiloff-Smith, Annette; Dimitriou, Dagmara – Developmental Science, 2017
Sleep plays an active role in memory consolidation. Because children with Down syndrome (DS) and Williams syndrome (WS) experience significant problems with sleep and also with learning, we predicted that sleep-dependent memory consolidation would be impaired in these children when compared to typically developing (TD) children. This is the first…

Zinke, Katharina; Zeintl, Melanie; Rose, Nathan S.; Putzmann, Julia; Pydde, Andrea; Kliegel, Matthias – Developmental Psychology, 2014
Recent studies suggest that working memory training may benefit older adults; however, findings regarding training and transfer effects are mixed. The current study aimed to investigate the effects of a process-based training intervention in a diverse sample of older adults and explored possible moderators of training and transfer effects. For…

Shamama-tus-Sabah, Syeda; Gilani, Nighat; Wachs, Theodore D. – International Journal of Behavioral Development, 2011
Recent findings from Western developed countries have linked home chaos to children's cognitive performance and behavioral problems. In the present paper we test whether the same pattern of associations can be replicated in a non-Western developing country. Our sample was 203 Pakistani primary school children. To assess home chaos the Confusion,…

Burns, Nicholas R.; Lee, Michael D.; Vickers, Douglas – Journal of Problem Solving, 2006
Studies of human problem solving have traditionally used deterministic tasks that require the execution of a systematic series of steps to reach a rational and optimal solution. Most real-world problems, however, are characterized by uncertainty, the need to consider an enormous number of variables and possible courses of action at each stage in…

Hubbs-Tait, Laura – 1986
A task was developed to differentiate the reasoning of elementary school students in fifth, sixth, and seventh grades. Subjects completed 16 matrices containing two, three, or four dimensions and varying in the embeddedness of the dimensions. They also solved a formal operational task assessing ability to isolate, exclude, and include variables.…
