A key developmental task of childhood is to gain autonomy and independence from parents and caregivers. Critical to this individualization process is the development of prospective memory (PM), the capacity to remember to carry out future intentions. In recent studies, children's PM performance has been associated with executive functions (EF). A closer inspection of the literature, however, suggests a differential impact of the three EF (updating, inhibition, and shifting) across different PM task types. The current study examined EF and PM capacities of 212 6-to 11year-old children, examining for the first time both focal and nonfocal event-based PM tasks as well as a time-based PM task in a single sample. Results show that age-differences did not persist above and beyond age differences in children's executive resources. Specifically, updating predicted children's performance on all PM tasks, inhibition predicted performance on both eventbased PM tasks, whereas shifting was specifically deployed by the nonfocal event-based task. Supplementary analyses of the time-based PM task illustrate how children monitor the progression of time and how preparatory processes support PM task performance. In sum, the current study presents the first comprehensive look at the specific role of age and three core EF in school-aged children's PM performance.

The present study targeted the question of whether focal versus nonfocal prospective memory (PM) can be distinguished on a construct level, and if so, to what extent individual differences in these two constructs are related to individual differences in facets of controlled attention and episodic memory. 315 individuals (aged 20-68 years) were administered focal and nonfocal PM tasks as well as indicators measuring updating, inhibition, shifting, and episodic memory. Latent variable modeling revealed that focal and nonfocal PM were two distinguishable but related constructs. Furthermore, analyses showed that focal PM was more strongly related to inhibition, while nonfocal PM was more strongly related to shifting. Present data support the conceptual hypothesis that focal and nonfocal PM should be conceptualized as two distinguishable but related constructs. Moreover, they suggest that both have some but distinct associations to controlled attention.

Objective: To quantify goal-directed behavior and ADHD symptoms in naturalistic conditions, we developed a virtual reality task, EPELI (Executive Performance in Everyday LIving), and tested its predictive, discriminant and concurrent validity. Method: We collected EPELI data, conventional neuropsychological task data, and parent-ratings of executive problems and symptoms in 38 ADHD children and 38 typically developing controls. Results: EPELI showed predictive validity as the ADHD group exhibited higher percentage of irrelevant actions reflecting lower attentional-executive efficacy and more controller movements and total game actions, both indicative of hyperactivity-impulsivity. Further, the five combined EPELI measures showed excellent discriminant validity (area under curve 88 %), while the correlations of the EPELI efficacy measure with parent-rated executive problems (r = .57) and ADHD symptoms (r = .55) pointed to its concurrent validity. Conclusion: We provide a proof-of-concept validation for a new virtual reality tool for ecologically valid assessment of ADHD symptoms.

The interplay of cognitive abilities that constitute the process of ‘remembering to remember' is referred to as prospective memory. Prospective memory is an essential ability to meet everyday life challenges across the life span, constitutes a key element of autonomy and independence and is especially important in old age with increasing social and health-related prospective memory demands. The present paper first presents major findings from the current state of the art in research on age effects in prospective memory. In a second part, it presents four focus areas for future research outlining possible conceptual, methodological, and neuroscientific advancements.
