DeCaro, Marci S.; Rittle-Johnson, Bethany – Journal of Experimental Child Psychology, 2012
Both exploration and explicit instruction are thought to benefit learning in many ways, but much less is known about how the two can be combined. We tested the hypothesis that engaging in exploratory activities prior to receiving explicit instruction better prepares children to learn from the instruction. Children (159 second- to fourth-grade…

Mann, Anne; Moeller, Korbinian; Pixner, Silvia; Kaufmann, Liane; Nuerk, Hans-Christoph – Journal of Experimental Child Psychology, 2012
The development of two-digit number processing in children, and in particular the influence of place-value understanding, has recently received increasing research interest. However, place-value influences leading to decomposed processing have not yet been investigated for multi-digit numbers beyond the two-digit number range in children.…

Geary, David C.; Hoard, Mary K.; Nugent, Lara – Journal of Experimental Child Psychology, 2012
Children's (N = 275) use of retrieval, decomposition (e.g., 7 = 4+3 and thus 6+7 = 6+4+3), and counting to solve additional problems was longitudinally assessed from first grade to fourth grade, and intelligence, working memory, and in-class attentive behavior was assessed in one or several grades. The goal was to assess the relation between…

Moret-Tatay, Carmen; Perea, Manuel – Journal of Experimental Child Psychology, 2011
The lexical decision task is probably the most common laboratory visual word identification task together with the naming task. In the usual setup, participants need to press the "yes" button when the stimulus is a word and the "no" button when the stimulus is not a word. A number of studies have employed this task with developing readers;…

Vukovic, Rose K.; Lesaux, Nonie K. – Journal of Experimental Child Psychology, 2013
This longitudinal study examined how language ability relates to mathematical development in a linguistically and ethnically diverse sample of children from 6 to 9 years of age. Study participants were 75 native English speakers and 92 language minority learners followed from first to fourth grades. Autoregression in a structural equation modeling…

Hecht, Steven A.; Vagi, Kevin J. – Journal of Experimental Child Psychology, 2012
The purpose of this study was to explore individual patterns of strengths and weaknesses in children's mathematical knowledge about common fractions. Tasks that primarily measure either conceptual or procedural aspects of mathematical knowledge were assessed with the same children in their fourth- and fifth-grade years (N = 181, 56% female and 44%…

Boyer, Ty W.; Levine, Susan C. – Journal of Experimental Child Psychology, 2012
The current experiments examined the role of scale factor in children's proportional reasoning. Experiment 1 used a choice task and Experiment 2 used a production task to examine the abilities of kindergartners through fourth-graders to match equivalent, visually depicted proportional relations. The findings of both experiments show that accuracy…

LeFevre, Jo-Anne; Berrigan, Lindsay; Vendetti, Corrie; Kamawar, Deepthi; Bisanz, Jeffrey; Skwarchuk, Sheri-Lynn; Smith-Chant, Brenda L. – Journal of Experimental Child Psychology, 2013
We examined the role of executive attention, which encompasses the common aspects of executive function and executive working memory, in children's acquisition of two aspects of mathematical skill: (a) knowledge of the number system (e.g., place value) and of arithmetic procedures (e.g., multi-digit addition) and (b) arithmetic fluency (i.e.,…

Kuhn, Deanna; Katz, Jared – Journal of Experimental Child Psychology, 2009
We present evidence suggesting that the effect of self-explanations on learning is not always beneficial and, in fact, in some contexts has a detrimental effect. Over eight sessions, fourth-graders engaged in investigation of a database with the goal of identifying causal effects. In a separate task, children in one condition also generated…

Caviola, Sara; Mammarella, Irene C.; Cornoldi, Cesare; Lucangeli, Daniela – Journal of Experimental Child Psychology, 2012
The involvement of working memory (WM) was examined in two types of mental calculation tasks: exact and approximate. Specifically, children attending Grades 3 and 4 of primary school were involved in three experiments that examined the role of verbal and visuospatial WM in solving addition problems presented in vertical or horizontal format. For…

Liu, Phil D.; Chung, Kevin K. H.; McBride-Chang, Catherine; Tong, Xiuhong – Journal of Experimental Child Psychology, 2010
Among 30 Hong Kong Chinese fourth graders, sensitivities to character and word constructions were examined in judgment tasks at each level. There were three conditions across both tasks: the real condition, consisting of either actual two-character compound Chinese words or real Chinese compound characters; the reversed condition, with either the…

Popliger, Mina; Talwar, Victoria; Crossman, Angela – Journal of Experimental Child Psychology, 2011
Children tell prosocial lies for self- and other-oriented reasons. However, it is unclear how motivational and socialization factors affect their lying. Furthermore, it is unclear whether children's moral understanding and evaluations of prosocial lie scenarios (including perceptions of vignette characters' feelings) predict their actual prosocial…

Jimenez, Juan E.; Rodriguez, Cristina; Ramirez, Gustavo – Journal of Experimental Child Psychology, 2009
This study was designed to examine the prevalence, cognitive profile, and home literacy experiences in subtypes of Spanish developmental dyslexia. The subtyping procedure used comparison with chronological-age-matched and reading-level controls on reaction times and accuracy responses to high-frequency words and pseudowords. Using regression-based…

McBride-Chang, Catherine; Chung, Kevin K. H.; Tong, Xiuhong – Journal of Experimental Child Psychology, 2011
Because Chinese character learning typically relies heavily on rote character copying, we tested independent copying skill in third- and fourth-grade Chinese children with and without dyslexia. In total, 21 Chinese third and fourth graders with dyslexia and 33 without dyslexia (matched on age, nonverbal IQ, and mother's education level) were given…

Hattikudur, Shanta; Alibali, Martha W. – Journal of Experimental Child Psychology, 2010
This study investigated whether instruction that involves comparing the equal sign with other relational symbols is more effective at imparting a relational interpretation of the equal sign than instruction about the equal sign alone. Third- and fourth-grade students in a comparing symbols group learned about the greater than, less than, and equal…
