Previous literature suggests that children with attention-deficit/hyperactivity disorder (ADHD) exhibit a positive bias (PB), defined as an over-estimation of one's own ability as compared with actual ability. However, it is possible that the larger discrepancy (i.e., PB) in children with ADHD is accounted for by lower competence levels rather…

The present study evaluated: (1) the effects of two training programs designed for promoting Theory of Mind (ToM) skills in children aged 7/8; and (2) the relations between second-order recursive thinking (II-order-RT), advanced-ToM (Adv_ToM) and metacognition. Ninety-one 7- to 8-year-old children were assigned to one of three training conditions:…

Effective communication requires an understanding of the interlocutor's perspective. Being able to infer someone else's knowledge about a situation is a critical skill in any communication and social interaction. These abilities are part of Theory of Mind (ToM) skills and are known to be impaired in Down syndrome (DS). It therefore makes sense to…

Three hundred and forty-one children (M[subscript age] = 9,0 years) engaged in a series of science tasks in collaborative, same-sex pairs or did not interact. All children who collaborated on the science tasks advanced in basic-level understanding of the relevant task (motion down an incline). However, only boys advanced in their conceptual…

This study investigated potential differences in inductive behavioural and verbal strategy-use between children (aged 6-8 years) from indigenous and non-indigenous backgrounds. This was effected by the use of an electronic device that could present a series of tasks, offer scaffolded assistance and record children's responses. Children from…

We tested whether mental rotation training improved math performance in 6- to 8-year-olds. Children were pretested on a range of number and math skills. Then one group received a single session of mental rotation training using an object completion task that had previously improved spatial ability in children this age (Ehrlich, Levine, &…

Determining which dimensions of social classification are culturally significant is a developmental challenge. Some suggest this is accomplished by differentially privileging intrinsic visual cues over nonintrinsic cues (Atran, 1990; Gil-White, 2001), whereas others point to the role of noun labels as more general promoters of kind-based reasoning…

The present study tested the "interference hypothesis"-that learning and using more advanced representations and strategies requires the inhibition of prior, less advanced ones. Specifically, it examined the relation between inhibitory control and number line estimation performance. Experiment 1 compared the accuracy of adults' (N = 53)…

A test-intervention-test study was conducted investigating the role of intelligence on four parameters of strategy competence in the context of a numerosity judgment task. Moreover, the effectiveness of two feedback types on these four parameters was tested. In the two test sessions, the choice/no-choice method was used to assess the strategy…

The present study investigated interpretation bias and reduced evidence for danger (RED) bias in 49 children with social phobia and 49 nonsocially anxious children between the ages of 8 and 14 years, using an ambiguous stories task. A posttreatment and follow-up measure was included for 26 of the socially phobic children to examine whether there…

Aims: This study sought to explore the use of a novel approach that incorporates dynamic testing and tangible electronics in the assessment of children's learning potential and strategy use. Sample: A total of 77 children with a mean age 8.9 years participated in the study; half of them were dynamically tested using graduate prompt techniques; the…

This investigation used an ABAB withdrawal design to determine the effect of self-monitoring using the MotivAider® (MotivAider, 2000) on percentage of intervals of on-task behavior by an 11-year old male with a moderate intellectual disability who attended a rural middle school. The MotivAider® is a small device, the size of a pager, which can be…

Many educational Randomized Controlled Trials (RCTs) collect baseline versions of outcome measures (pretests) to be used in the estimation of impacts at posttest. Although pretest measures are not necessary for unbiased impact estimates in well executed experimental studies, using them increases the precision of impact estimates and reduces sample…

This study aimed to isolate the effects of the two input activities in Processing Instruction: referential activities, which force learners to focus on a form and its meaning, and affective activities, which contain exemplars of the target form and require learners to process sentence meaning. One hundred and twenty 12-year-old Taiwanese learners…
