Our study on 328 five- to six-year-old kindergarteners (mainly White European living in France, 152 girls) shows that children who do not count on their fingers and undergo finger counting training exhibit drastic improvement in their addition skills from pre-test to post-test (i.e., accuracy from 37.3% to 77.1%) compared to a passive control…

Several studies have previously investigated the effects of sticky mittens training on reaching and grasping development. However, recent critique casted doubts on the robustness of the motor effect of this training. The current study presents a pre-registered report that aimed to generalize these effects to Swedish infants. Three-month-old…

This study investigated the influence of first language (L1) phonology on second language (L2) early reading skills in Sylheti-English bilinguals (N = 58; 48% girls; British Bangladeshi) and their monolingual-English peers (N = 43; 45% girls; 96% White British, 4% multiethnic British) in a diaspora context.

Mothers of 821 children of the Copenhagen Perinatal Cohort recorded 20 developmental milestones at a 3-year examination, and all…

This study trained children to master logical fallacies and examined how learning is related to processing efficiency and fluid intelligence (gf). A total of one hundred and eighty 8- and 11-year-old children living in Cyprus were allocated to a control, a limited (LI), and a full instruction (FI) group. The LI group learned the notion of logical…

This report investigates tool learning and its relations to executive functions (EFs) in toddlers. In Study 1 (N = 93), 18-, 20-, 22-, and 24-month-old children learned equally well to choose a correct tool from observation, whereas performance based on feedback improved with age. Knowledge transfer showed significant progress after 22 months of…

Investigates the relative efficacy of three training procedures in improving serial recall in kindergarten children who either showed no tendency to rehearse or rehearsed inconsistently at a serial recall pretest. Self-instructional training, an induced rehearsal procedure, and a practice control condition comprised the three training procedures.…

Confirms the existence of a right-hemisphere advantage in the process of discriminating between face stimuli. The advantage was weaker in females than in males. No hemispheric transfer of learning was observed. Subjects were 18 infants of 42 weeks who were presented with an operant conditioning situation in which they discriminated between their…

Three methods for training communication skills, social-conflict method, modeling, and conflict-modeling, were devised to correct specific deficiencies in children's communication behavior. Subjects were 40 kindergarten, first-, second-, and third-grade children. (CM)
