Background. Prosocial behavior is the key component of social and interpersonal relations. One of the elements of prosociality is helping behavior, which emerges already in early childhood. Researchers have identified several domains of helping behavior: instrumental helping, comforting another person, and sharing resources with others. The development of helping behavior can depend on a number of factors: children’s age, the social situation of development, communication skills, and the ability to understand the feelings and needs of another person.

Objective. In Study 1, the main goal was to determine the effects of age and cognitive, language, and motor development on instrumental helping skills in early childhood. The goal of Study 2 was to estimate the effects of rearing in an adverse social environment by comparing the capacity for instrumental helping in family-raised and institutionalized children.

Design. The authors examined toddlers’ (N = 198) ability to initiate spontaneous helping and the factors that may influence it. Cognitive, language, and fine motor skills were measured by the Bayley Scales of Infant and Child Development, 3rd edition. Children’s instrumental helping behavior was assessed according to the procedure presented by Warneken and Tomasello, with a few modifications.

Results. Study 1 demonstrated that children’s ability to initiate helping was dependent on their age: the non-helpers were significantly younger than the helpers. Children’s language skills also played a significant role in their helping behavior. The children with higher language skills helped the adult more often and more quickly. Study 2 demonstrated that institutional placement per se was not related to toddlers’ ability to initiate helping. Language ability was associated with helping behavior both in institution- and family-reared toddlers.

Conclusion. Instrumental helping in early childhood is related to children’s age, language skills, and rearing conditions.

Background. Early childhood is a critically important period of development for the formation of personality. Many studies provide convincing proof that elements of moral behavior are observable already in the early stages of ontogenesis. Of particular interest for psychophysiologists is the question of whether the capacity for moral evaluation in younger children can be reflected in specific EEG patterns characteristic of them.

Objective. To establish specific patterns of EEG oscillations, including the frontal alpha-rhythm asymmetry, in young children who are prone to evaluate differently the behaviors of “helping” and “hindering” puppets.

Design. Fifty-six children aged 16 to 42 months participated in the study. To measure the level of moral evaluation in children, we used the method designed by B. Kenward and M. Dahl, with some modifications. The EEG was recorded when children distributed resources among the puppet-actors.

Results. When deciding how to distribute resources among the puppets, the children with a higher moral evaluation index demonstrated an overall higher alpha rhythm amplitude, as well as a specific pattern of theta rhythm amplitude. The moral evaluation indices correlated with alpha asymmetry in the EEG loci F7 and F8.

Conclusions. 1. Significant differences in EEG patterns were found between the children who showed different levels of moral evaluation. Children with higher indices of moral evaluation showed a higher alpha rhythm amplitude when deciding how to distribute resources among the puppets, depending on the puppets’ “helping” or “hindering” behavior. 2. The theta rhythm oscillation patterns differed significantly between the samples of children with different moral evaluation indices. 3. Alpha asymmetry in the dorsolateral prefrontal cortex (loci F7, F8) was correlated with the moral evaluation indices, indicating an increased activation in the prefrontal regions of the left hemisphere in children with a more developed understanding of moral behavior.
