Previous studies demonstrated that dual-task impairments are higher in children than in young adults. A previous study systematically assessed the sources of these larger dual-task impairments by identifying age-related differences in capacity limitations during dual-task processing. Capacity limitations in central cognitive processes were present…

The architecture of sleep undergoes distinct changes during childhood and early adolescence. Slow wave sleep is involved in memory processing and may support active consolidation of newly encoded representations to support the formation of abstracted "gist" memories. Here, we examined sleep and overnight memory formation in German school…

It has been suggested that due to functional similarity, sortal object individuation might be a primordial form of psychological essentialism. For example, the relative independence of identity judgment from perceived surface features is a characteristic of essentialist reasoning. Also, infants engaging in sortal object individuation pay more…

Several studies have demonstrated that individual differences in processing speed fully mediate the association between age and intelligence, whereas the association between processing speed and intelligence cannot be explained by age differences. Because measures of processing speed reflect a plethora of cognitive and motivational processes, it…

The significant interplay between self-efficacy, autonomy support and approaches to learning in adolescent students is widely recognized. However, less is known about whether substantial differences exist between early and middle adolescent students from schools with different environments. To close this research gap, this study used latent mean…

Delay-induced forgetting refers to the finding that memory for studied material typically decreases as the delay between study and test is increased. The results of 3 experiments are reported designed to examine whether this form of forgetting is primarily caused by interference effects or contextual drift effects when people engage in neutral…

Little is known about how children generate options for taking action in familiar situations or how they select which action option to actually perform. In this article, we explore the interplay between option generation and selection from a developmental perspective using sports as a testbed. In a longitudinal design with four measurement waves,…

The inclusion of human-like shapes like arms or faces in rather abstract pictures triggers the tendency of anthropomorphism, which is defined as the attribution of human characteristics to nonhuman objects. Anthropomorphism-triggering features in digital learning materials were found to enhance the performance of students. However, the probability…

The experiment analyzed reactions of 115 first- to fourth-graders after realizing that they performed worse than they expected in a computer game. Based on the VIOLEX model of expectation violation, we assessed immunization against achievement feedback, assimilation (striving to increase performance), and accommodation (willingness for expectation…

This study examines the discourse basis for referent accessibility and its relation to the choice of referring expressions by children with Autism Spectrum Disorder (ASD) and typically developing children. The aim is to delineate how the linguistic and extra-linguistic context affects referent accessibility to the speaker. The study also examines…

Hindsight bias is the tendency to overestimate one's prior knowledge of a fact or event after learning the actual fact. Recent research has suggested that age-related differences in hindsight bias may be based on age-related differences in inhibitory control. We tested whether this explanation held for 3 cognitive processes assumed to underlie…

Creativity is a broad and complex construct, difficult to define and to quantify, assumed to introduce new impulses into science education (STEM), and leading to better acceptance of science by adolescents. Therefore, increasing efforts are being undertaken to integrate traditional creativity (Arts), in modifying STEM to STEAM. Consequently, a…

The main goal of this study was to examine whether different types of verbal labeling can influence age-related changes in the dynamic control of behavior by inducing either a proactive or reactive mode of control. Proactive control is characterized by a strong engagement in maintaining task-relevant information to be optimally prepared while…

This large-scale study examined the development of time-based prospective memory (PM) across childhood and the roles that working memory updating and time monitoring play in driving age effects in PM performance. One hundred and ninety-seven children aged 5 to 14 years completed a time-based PM task where working memory updating load was…

Two studies were conducted to investigate effects of domain knowledge on metacognitive monitoring across the life span in materials of different complexity. Participants from 4 age groups (3rd-grade children, adolescents, younger and older adults) were compared using an expert-novice paradigm. In Study 1, soccer experts' and novices'…
