The delay of gratification (DoG) in children is widely investigated with an experimental procedure originally called the “marshmallow test,” whereas the studies on self-regulation (SR) in adolescents and adults usually use self-report questionnaires. Delay discounting (DD) measures simplify the DoG procedure and focus on monetary rewards. The aim of this study was to investigate age differences in DoG and DD from childhood to old age using a test that is suitable for both children and adults. Furthermore, investigations were conducted on the association between DoG/DD and two future orientation constructs [future time perspective (FTP) and episodic future thinking (EFT)] as well as age differences in these constructs. Participants from five age groups (9–14, 18–25, 35–55, 65–80, 80+) participated in the study (N = 96). While we found no age difference for DoG, DD was the lowest [i.e., self-control (SC) was the highest] in young/middle adults; however, it was the highest (i.e., SC was the lowest) in children and old/oldest adults. Furthermore, we found significant age differences for DD and FTP. As predicted, there were strong correlations between DoG and FTP and between DD and FTP, but not between DoG/DD and EFT. These results indicate that age differences in SR vary across the measures used. Individuals who generally think and act in a future-oriented manner have a stronger ability to delay gratification.

The goal of this study was to examine whether a subject’s emotional competence correlates to attachment styles and parenting styles in children and their parents. The study was conducted with fifty children (9–11 years old) and their parents, both of whose emotional competence (EKF) and parenting style (PAQ) were measured. The attachment styles of parents and children were measured with the Adult Attachment Scale (AAS) and the Bochumer Bindungstest (BoBiTe), respectively. The findings provide initial support to the assumption that attachment is related to emotional competence in parents. This relationship, however, was not significantly correlated in children. In addition, authoritative parenting and permissive parenting were significantly associated with emotional competence in parents. Emotional competence in children showed to be associated with an authoritative parenting style.
