Cognitive development in infancy essay


cognitive development in infancy essay

behaviour that result as a consequence of acquiring perceptual or motor expertise. Some developmental psychologists argue that the human infant is born with innate modules and core knowledge relevant to the physical and social world. The obvious importance of social information processing, and the evidence for specialization of the adult brain for language and face processing, has led some to speculate that there are pre-specified modules within the infant brain to process socially relevant information. Although converging evidence for this claim comes from associations with resting frontal electroencephalographic responses and impairments in children with a neurochemical deficit in the prefrontal cortex resulting from Phenylketonuria, as yet no direct functional imaging on human infants during such object retrieval tasks has been. Researchers have also investigated the development of working memory in infants. Advertisements: For example, whereas there is a rapid increase in synaptogenesis around the time of birth for all cortical areas studied, the most rapid burst of synapse formation and the peak density of synapses occur at different ages in different areas. Synaptogenesis starts at the same time in the prefrontal cortex, but the density of synapses increases much more slowly and does not reach its peak until well after the first year. The extent of the parallels between adult perceptual expertise and infant perceptual development remains unclear. This biased sampling of the visual environment over the first days and weeks of life might ensure the appropriate specialization of later developing cortical circuitry. However, as with the processing of inanimate objects, there is now an emerging consensus centred on the middle-ground, namely that infants are born with biases to attend to and process certain stimuli differently, and that these biases shape subsequent learning and plasticity. A major challenge to the developing perceptual system is to segment parts of the visual input into separate objects.

Extending this idea to development means that we should observe changes in the response properties of cortical regions during ontogeny as regions interact and compete with each other to acquire their roles in new computational abilities. At these stage infants are generally attracted to bright colors, and show response to sound by turning towards the direction of the sound. For example, when event-related potentials are recorded during passive exposure to faces, the resulting component that is sensitive to upright human faces (the N170) in adults is much more broadly tuned in infants. Others propose that many of the changes in behaviour observed during infancy are the result of general mechanisms of learning and plasticity. 1892 Words 8 Pages, this paper is going to carry out a literature review on cognitive development in infants. There is a continuing rise in overall resting brain metabolism (glucose uptake) after the first year of life, with a peakabout 150 of adult levelsat around 4-5 years of age for some cortical areas. Studies have indicated that infants between the ages of three and seven phd accounting thesis weeks have the ability to recognize shapes and pictures of human faces (Goswami, 1994,. Studies have indicated that cognitive development in infants starts before they are born. In another example, maturation within the frontal lobes has been related to advances in the ability to reach for desirable objects towards the end of the first year.
