Pathways to Arithmetic Fact Retrieval and Percentage Calculation in Adolescents
Peer reviewed Peer reviewed
Direct linkDirect link
Träff, Ulf; Skagerlund, Kenny; Olsson, Linda; Östergren, Rickard – British Journal of Educational Psychology, 2017
Background: Developing sufficient mathematical skills is a prerequisite to function adequately in society today. Given this, an important task is to increase our understanding regarding the cognitive mechanisms underlying young people's acquisition of early number skills and formal mathematical knowledge. Aims: The purpose was to examine whether…

Namkung, Jessica M.; Fuchs, Lynn S. – Grantee Submission, 2015
The purpose of this study was to examine the cognitive predictors of calculations and number line estimation with whole numbers and fractions. At-risk 4th-grade students (N = 139) were assessed on 7 domain-general abilities (i.e., working memory, processing speed, concept formation, language, attentive behavior, and nonverbal reasoning) and…

Counting and RAN: Predictors of Arithmetic Calculation and Reading Fluency
Peer reviewed Peer reviewed
Direct linkDirect link
Koponen, Tuire; Salmi, Paula; Eklund, Kenneth; Aro, Tuija – Journal of Educational Psychology, 2013
This study examined whether counting and rapid automatized naming (RAN) could operate as significant predictors of both later arithmetic calculation and reading fluency. The authors also took an important step to clarify the cognitive mechanisms underlying these predictive relationships by controlling for the effect of phonological awareness and…

Working Memory Does Not Dissociate between Different Perceptual Categorization Tasks
Peer reviewed Peer reviewed

Lewandowsky, Stephan; Yang, Lee-Xieng; Newell, Ben R.; Kalish, Michael L. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2012
Working memory is crucial for many higher level cognitive functions, ranging from mental arithmetic to reasoning and problem solving. Likewise, the ability to learn and categorize novel concepts forms an indispensable part of human cognition. However, very little is known about the relationship between working memory and categorization. This…

Mathematical Development: The Role of Broad Cognitive Processes
Peer reviewed Peer reviewed
Direct linkDirect link
Calderón-Tena, Carlos O. – Educational Psychology in Practice, 2016
This study investigated the role of broad cognitive processes in the development of mathematics skills among children and adolescents. Four hundred and forty-seven students (age mean [M] = 10.23 years, 73% boys and 27% girls) from an elementary school district in the US southwest participated. Structural equation modelling tests indicated that…

3-D Interpolation in Object Perception: Evidence from an Objective Performance Paradigm
Peer reviewed Peer reviewed
Direct linkDirect link
Kellman, Philip J.; Garrigan, Patrick; Shipley, Thomas F.; Yin, Carol; Machado, Liana – Journal of Experimental Psychology: Human Perception and Performance, 2005
Object perception requires interpolation processes that connect visible regions despite spatial gaps. Some research has suggested that interpolation may be a 3-D process, but objective performance data and evidence about the conditions leading to interpolation are needed. The authors developed an objective performance paradigm for testing 3-D…
