The perception of spatial and successive contexts of auditory information develops during human ontogeny. We compared event-related potentials (ERPs) recorded in 5- to 6-year-old children (N = 15) and adults (N = 15) in response to a digital series with omitted digits to explore age differences in the perception of successive auditory information. In addition, ERPs in response to the sound of falling drops delivered binaurally were obtained to examine the spatial context of auditory information. The ERPs obtained from the omitted digits significantly differed in the amplitude and latency of the N200 and P300 components between adults and children, which supports the hypothesis that the perception of a successive auditory structure is less automated in children compared with adults. Although no significant differences were found in adults, the sound of falling drops presented to the left ears of children elicited ERPs with earlier latencies and higher amplitudes of P300 and N400 components in the right temporal area. Stimulation of the right ear caused increasing amplitude of the N100 component in children. Thus, the observed differences in auditory ERPs of children and adults reflect developmental changes in the perception of spatial and successive auditory information.
The article reveals an attempt of the author to analyze the development of personality and its main components in ontogenesis using the system-structural approach. We regard these psychological phenomena as multidimensional, multilevel holistic formations, the origin of which, further development and functioning are characterized by distinct heterochrony. Our study of time phenomenon in personality evolution is based on B. Ananyev's definition of the person's age not only as ontogenetic phase succession but also as social life of a person, as well as the history of personality formation in a particular society at a certain stage of its historical development. As a methodological basis for this analysis of personality and its ontogenetic development we use the system approach and time phenomenon as an integral characteristic of person's evolution according to B. Ananyev.
