A foundational mechanism underlying human cooperation is reciprocity. In the context of repeated interactions with others, it is not always clear the degree to which in-kind responses reflect responsiveness to partners' prior behaviors ("reactive" responses), an interest unrelated to the partner ("nonreactive" responses), or…

Background: Self-regulation has frequently been shown to be context-sensitive, suggesting the influence of different cultural contexts on its development. However, up until now, self-regulation has been mainly studied in Western countries with similar cultural contexts. Objective: Thus, with the present study we compared self-regulation of…

Delay of gratification tasks have an impressive predictive value for various outcomes and are designed to measure self-regulation. Since many behavioural and psychological conditions in children are related to limitations in self-regulation, the extent to which delay tasks can be used as a screening for the detection of psychopathology is…

Research Findings: Prosocial behavior in early childhood can be assessed by various informants and methodologies, but the information each provides may differ in meaningful ways. The present study measured and compared young children's (N = 486; age: M = 48.51 months, SD = 8.22) prosocial behavior based on parent reports, teacher reports, and…

Findings from previous cross-sectional studies showed that while toddlers around their first birthday imitate selectively, that is, they systematically omit some kinds of target action steps or they copy only the goal, but not the means of the modeled actions, older toddlers imitate more exactly. The aim of the present article is to provide…

From a young age, children in Western, industrialized societies overimitate others' actions. However, the underlying motivation and cultural specificity of this behavior have remained unclear. Here, 3- to 8-year-old children (N = 125) from two rural Namibian populations (Haillom and Ovambo) and one urban German population were tested in two…

Research Findings: A successful transition from preschool to elementary school requires a high level of behavioral adaptation. The aim of our study was to analyze child-related factors in preschool that facilitate a positive behavioral adaptation in the transitional period to elementary school. A cluster analysis was conducted with the data from…

This cross-cultural study investigates how maternal task assignment relates to toddlers' requested behavior and helping between 18 and 30 months. One hundred seven mother-child dyads were assessed in three different cultural contexts (rural Brazil, urban Germany, and urban Brazil). Brazilian mothers showed assertive scaffolding (serious and…

Unmet mental health needs are common in young children. Recent research on mental health care utilization has focussed mainly on parental perspectives. This study seeks to determine which types of behaviours exhibited by children predict the perceived need for action among both parents and daycare teachers. Parents and daycare teachers reported on…

The present article aims to show how to model longitudinal change in cohort sequential data applying latent true change models using Mplus' multi-group approach. The underlying modeling ideas are described and explained in this article. As an example, change in internalizing problem behaviors between the age of 8 and 13 years is modeled and…

The present study investigated a direct assessment of behavioral self-regulation (the Head-Toes-Knees-Shoulders; HTKS) and its contribution to early academic achievement among young children in Germany and Iceland. The authors examined the psychometric properties and construct validity of the HTKS, investigated gender differences in young…

The present longitudinal study aimed to investigate the influence of ADHD symptoms on reading development in elementary schoolchildren. To this end, repeated assessments of ADHD symptoms (teacher ratings of inattention, hyperactivity, and impulsivity) and reading achievement (standardized tests of decoding speed and text comprehension) were…

Research Findings: Behavior regulation, including paying attention, remembering instructions, and controlling action, contributes to children's successful adaptation to and functioning in preschool and school settings. This study examined the development of behavior regulation in early childhood and its potential contribution to individual…

Teacher-child relationships in early childhood are a crucial prerequisite for children's emotional, social and academic development. Therefore, it is important to be able to measure accurately the quality of interactions among them. The Student-Teacher Relationship Scale (STRS) is a widely accepted instrument in measuring the quality of…

In all human cultures, people gesture iconically. However, the evolutionary basis of iconic gestures is unknown. In this study, chimpanzees and bonobos, and 2- and 3-year-old children, learned how to operate two apparatuses to get rewards. Then, at test, only a human adult had access to the apparatuses, and participants could instruct her about…
