The present study investigated the role of cognitive and linguistic precursors to early numeracy skills to examine the interrelations between the development of linguistic and numeracy skills. General intelligence, working memory, phonological awareness, grammatical ability, and early numeracy skills were assessed in 75 first (mean age 6.1) and 55…

Verbal ability comprises receptive (understanding) and active (producing) facets. While the first (e.g. as literacy in PIRLS and PISA) is frequently analyzed in its relationship to further cognitive abilities and parental attributes the latter is rarely investigated. The present study using data from N=280 students aged 9 to 14 years investigated…

Emphasizing task importance, which is regarded as a way of motivating engaged behavior, may increase an individual's anxiety. The present research investigated whether academic self-efficacy could moderate the maladaptive relation between task importance and test anxiety. 1978 and 1670 Grade 9 Singaporean students participated in a survey related…

This research investigates how visuo-spatial abilities (such as mental rotation--MR--and visuo-spatial working memory--VSWM--) work together to influence the recall of environmental descriptions. We tested a mediation model in which VSWM was assumed to mediate the relationship between MR and spatial text recall. First, 120 participants were…

This study investigates the relationship between working memory and language in young children growing up in a multilingual environment. The aim is to explore whether mechanisms of short-term storage and cognitive control hold similar relations to emerging language skills and to investigate if potential links are mediated by related cognitive…

If tests of cognitive ability are repeatedly taken, test scores rise. Such retest effects have been observed for a long time and for a variety of tasks. This study investigates retest effects on figural matrix items in an educational context. A short term effect is assumed for the direct retest administration in the same test session, and a long…

The present study investigated whether the marked sex difference in the original mental rotation test (MRT) is simply a result of sex differences in response strategies. Thirty-four participants (17 males, 17 females) completed the revised Vandenberg and Kuse MRT [Peters, M., Laeng, B., Latham, K., Jackson, M., Zaiyouna, R., & Richardson, C.…

This study investigates the relationships of domain-general cognitive abilities and domain-specific verbal and mathematical abilities to students' educational characteristics when two theoretically grounded, but competing structural models are applied. In the standard model, a single latent ability causes interindividual differences in the…

This study focused on unprompted changes in children's analogical reasoning on geometric tasks and the additional effect of a short training procedure. Participants were 36 grade 1 level children (M = 6;8 years) divided over a not-trained and a trained condition. The study was a 5-sessions migrogenetic procedure, with a follow-up test session…
