Learning behavioural responses and adapting them based on feedback is crucial from a young age, continuing to develop into young adulthood. This study examines the development trajectory and contributing factors from childhood to adulthood using a reversal learning paradigm. We tested 202 participants aged 10 to 22 in an online study, where they…

Both humans and non-human animals exhibit sensitivity to the approximate number of items in a visual array, as indexed by their performance in numerosity discrimination tasks, and even neonates can detect changes in numerosity. These findings are often interpreted as evidence for an innate 'number sense'. However, recent simulation work has…

This dissertation addresses the question of how structured out-of-school-time settings, such as afterschool programs and summer camps, are positioned to support children's engagement and learning in science. This study addresses a gap in the research literature that does not fully specify the nature of the out-of-school-time (OST) setting and that…

In this book, the author describes the complexity of the Self as the source of all human behavior. She will try to outline the structure of the Self, its normal growth and development, and the role of interaction with other living things in this process. Ms. Roeper sees the Self as a unit within us, which includes input from the brain and all…

This study examines object construction and the ages at which children developing under various environmental conditions achieve five of the landmarks in the Uzgiris-Hunt (1974) scale of object permanence. (Author)

Suggests that learning is a process undergoing change from infancy to adulthood and that the more consciously aware the learner is of the process, the more the learner can be in control. Presents the Performance Pathfinder Plan as a model of appropriate adult learning. (Author/DC)

Research programs of the human learning and behavior branch of the National Institute of Child Health and Human Development (NICHHD) are described in five sections of this document. The specific programs conducted in the areas of learning and cognitive development, development of communicative abilities, biological bases of behavioral development,…
