Response times, accuracy and event-related potentials were measured in 24 children (mean age 7.6 years), 24 juveniles (11.4 years) and 24 adults (23.8 years) during a mental rotation task with letters. Response time and error rates increased with angular displacements for all age groups. Increasing accuracy with increasing age suggested that this task was more difficult for younger participants...

Daytime napping undergoes a remarkable change in early childhood, and research regarding its relationship to cognitive development has recently accelerated. In this review, we summarize our current understanding of this relationship focusing on children aged <5 years. First, we evaluate different studies on the basis of the experimental design used and the specific cognitive processes they inve...

The topic of this chapter is the development of temporal understanding, and in particular the question as to when children can be said to be able to grasp temporal concepts such as 'before' and 'after'. One specific idea we wish to look at is that the development of temporal understanding, and the emergence of a grasp of temporal concepts, is closely linked to developments in children's underst...

neuropsychological studies have demonstrated that preclinical dementia accompanies a decreasing trend in cognitive state a few years prior to clinical diagnosis. sudden decline in episodic memory and semantic knowledge have been found to have the capability to differentiate patients in preclinical state of dementia from those experiencing normal aging. in addition, decline in episodic memory is...

This paper aims to compare cognitive development in humans and chimpanzees to illuminate the evolutionary origins of human cognition. Comparison of morphological data and life history strongly highlights the common features of all primate species, including humans. The human mother-infant relationship is characterized by the physical separation of mother and infant, and the stable supine postur...

Cognition is a field of thought processes by which an individual processes information through skills of perception, thinking, memory, learning and attention. Zinc deficiency may affect cognitive development by alterations in attention, activity, neuropsychological behavior and motor development. The exact mechanisms are not clear but it appears that zinc is essential for neurogenesis, neuronal...
