[Human cognitive activity during adaptation to short-term weightlessness]. / Poznavatel'naia deiatel'nost' lichnosti pri adaptatsii k kratkovremennoi nevesomosti

The differences in subjective sensations during the first exposure to short-term weightlessness are analyzed on the basis of the pattern of cognitive activity of test subjects and the scope of information they have received previously. The subjects with objective and productive types of cognitive behavior showed the most adequate and rapid adaptation to weightlessness. The subjects with a subjective and unproductive type of cognitive tactics exhibited great problems in adapting themselves to weightlessness, showing unusual psychic states like the "world peril" syndrome and psychic estrangement. Anticipation of the weightless environment based on the objective information previously obtained facilitated orientation and self-control in weightlessness.
