An increasing number of findings suggest that cognition is grounded in sensorimotor experiences. Research suggests that fine motor skills (FMS) link to cognitive abilities. Existing studies, however, lack conceptual and methodological differentiation regarding FMS and little is known about the directional nature of links. In study 1, we measured…

First-order and advanced theory of mind (ToM and AToM), and their structures and relations were investigated in 229 children aged 5-8 years. ToM was assessed using 6 tasks from the first-order ToM scale, while AToM was measured using an 18-item battery (higher-order false-belief understanding; strange stories; faux pas test; eyes test;…

Detecting self-generated actions and imitating other-generated actions are important abilities in order to interact with others. The relationship between these domains was investigated in 6-8-month-old infants. In a contingency-preference task, infants observed their own legs on a real-time and a delayed video display. In an imitation task, the…

Children's fine motor skills (FMS) are being increasingly recognized as an important aspect of preschool development; yet, we know very little about the experiences that foster their development. We utilized a parent-administered children's fine and gross motor activities questionnaire (MAQ) to investigate links with FMS. We recruited a sample of…

Children develop linguistic competencies during interactions with more knowledgeable others. Consequently, one way to support this development is by enhancing the home literacy environment (HLE) in which children live. In this study a non-intensive intervention procedure was developed to improve HLE and linguistic competencies of 125 German…

In 19 (sub)samples from seven countries (United States, Austria, Germany, Costa Rica, Ecuador, Vietnam, Brazil), we analyzed the impact of parental education compared with wealth on the cognitive ability of children (aged 4-22 years, total N = 15,297). The background of their families ranged from poor indigenous remote villagers to academic…

Few studies have investigated how preschool and primary school interact to influence children's cognitive development. The present investigation explores German children's numeracy skills between age 3 (1st year of preschool) and age 7 (1st year of primary school). We first identified the influence of preschool experience on development while…

The present study aims to investigate the association between parenting behaviours, children's daily activities and their cognitive development. Participants were 52 Turkish-German and 65 German pre-school children and their mothers, who were matched in terms of education level (10-12 years of schooling). Children's cognitive skills were assessed…

Studies the language proficiency of the Turkish returnees from Germany who were either born in Germany or emigrated there with their parents at a young age. Results indicate that returnees have a deficit in cognitive academic language proficiency compared to control groups and that a correlation exists between language proficiency in Turkish,…
