First-order theory of mind (ToM) development has shown to conform to a Guttman scale, with desire reasoning developing before belief reasoning. There have been attempts to test for internal consistency and scalability in advanced ToM, but not over a broad age range and only with a limited set of tasks. This 2-year longitudinal study (N = 155;…

Metacognitive control is an important factor for successful learning and has been shown to increase across childhood and adolescence. Only few studies have attempted to investigate the cognitive processes and psychological mechanisms that subserve metacognitively-based control and the development thereof. Accordingly, the aim of the current study…

This study examined longitudinal relations between early measures of prosocial action in infancy as well as cognitive and social-cognitive abilities, and the sharing behaviour of preschool children. The results reveal relations between delay-of-gratification at 24 months and inhibitory control at 30 months, and children's sharing at 5 years.…

Investigated four to six year olds' understanding of cognitive cuing in two experiments that used a strategic interaction paradigm. (PCB)

Four experiments studied 4- to 6-year-old children's understanding of inferential reasoning as a source of knowledge. To assess understanding that knowledge of relevant premises leads to knowledge of the conclusion, children had to judge the knowledge of another person, who was presented to the child as being aware of two premises.

Children were tested at ages four and six for recall of clusterable objects under play and sort conditions. Conceptual clustering predicted recall performance of six-year olds in both conditions and of four-year olds in the sort condition. The stability of memory variables was low with the exception of free recall. (BC)

Investigated relationships among metamemory, memory behavior, and memory performance of children aged 4 to 6 in two experiments. Results indicated an increase in preschoolers' ability to establish relationships between cues and targets even if these were not highly associated. (RWB)

Tested 32 4-year-olds and 32 6-year-olds for free and cued recall following either play-and-remember or sort-and-remember instructions and assessed them for their metamemory of the efficacy of conceptual and perceptual sorting strategies. Younger children recalled more items under sort-and-remember, whereas no recall differences were found for the…
