Actual problems of Internet-addiction




A. E. Voiskounsky

Cand. sci. (psychology), head res. ass., Department of psychology, Moscow State University, Moscow

Contemporary problems of psychology of addiction related to attempts to define behavioral patterns of addiction are discussed. The analysis is made on the data of Internet-addiction. Different viewpoints on the named problem are presented: qualification of Internet-addiction as a behavioral addiction that has little in common with clinical addiction as a behavioral phenomenon, as psychologists' misconception who mistakenly present this phenomenon as a kind of addiction.

Key words: addiction, Internet, behavioral addiction.

REFLECTION OF STIMULUS DURATION IN CHARACTERISTICS OF EVOKED POTENTIAL (PART 1)

There were investigated the mechanisms of perception of short duration stimuli in complex psychophysic and electroencephalographic study. Visual and auditory stimuli of different duration (200 - 1000 ms) were presented; EEG and subjective evaluation of stimulus duration were recorded in the experiment. Evoked potentials (EP) at F4, C4, T4, P4, F8 and C3 averaged from stimulus offset were analyzed. It was fond that amplitude of EP positive component (with latency of 300 ms for visual stimuli and 250 for auditory ones) was linearly correlated with subjective evaluation of stimulus duration for visual stimuli and as V-shape function - for auditory. This positive component is not sensitive to changing of stimulus duration if there is no instruction to evaluate it. The data obtained prove the role of frontal and central areas in the process of perception and evaluation of time interval.

Key words: evoked potentials, stimulus duration, evaluation of time interval.
