INTRODUCTION In this brief essay, I seek to demonstrate the significance of exploratory behavior for understanding cognitive development. Historically, organisms were thought to act solely in the service of achieving biologically significant goals, such as satisfying thirst, hunger, and reproductive drives. However, it became apparent that both animals and humans engage in behavior where the ad...

Oogenesis in Drosophila was initially studied as a model system to investigate the patterning of embryonic axis, however, it has since become a powerful model system for investigating various aspects of cellular, molecular and developmental biology. Oogenesis in Drosophila melanogaster is a complex developmental process which involves extensive cellular remodeling and communication [1-3]. The e...

The investigation of global developmental delay in preschool children varies between centres and between paediatricians. Following a literature search and review of the evidence base, guidelines were developed to assist in the assessment and management of such children presenting to secondary level services. Evidence supporting the use of genetic and biochemical investigations on a screening ba...

Cerebral palsy (CP) is the most severe physical disability within the spectrum of developmental delay. CP is an umbrella term describing a group of motor disorders, accompanied by many associated impairments. The disability is a result of injuries to the developing brain occurring any time from the first trimester of pregnancy through to early childhood. However, for the great majority, their f...

It is often assumed that similar domain-specific behavioural impairments found in cases of adult brain damage and developmental disorders correspond to similar underlying causes, and can serve as convergent evidence for the modular structure of the normal adult cognitive system. We argue that this correspondence is contingent on an unsupported assumption that atypical development can produce se...

BACKGROUND Although successful aging is most often defined by the absence of disease and disability, older adults consistently report aging successfully even in the presence of chronic illness and functional limitations. A more holistic way of looking at old age suggests transcendence may be an important missing criterion for successful aging. AIM Transcendence, a late life developmental proc...

Recent studies of developmental biology have shown that the genes controlling phenotypic characters expressed in the early stage of development are highly conserved and that recent evolutionary changes have occurred primarily in the characters expressed in later stages of development. Even the genes controlling the latter characters are generally conserved, but there is a large component of neu...

The Modern Synthesis of Darwinism and genetics regards non-genetic factors as merely constraints on the genetic variations that result in the characteristics of organisms. Even though the environment (including social interactions and culture) is as necessary as genes in terms of selection and inheritance, it does not contain the information that controls the development of the traits. S. Oyama...
