GENETIC LIMITS OF INTELLIGENCE

This study investigates how factors like age, education, training, sex, and emotional state affect the decision-making process, particularly in visual recognition tasks. By measuring the minimum information required to recognize visual images, correlations are drawn between anxiety levels and the number of contour fragments necessary for recognition. The findings indicate that higher levels of anxiety hinder visual signal recognition and decision acceptance. This suggests that emotional factors play a critical role in the integrative analysis of sensory information in the brain.

  1. GENETIC LIMITS OF INTELLIGENCE V V Lavrov, V.B.Valtzev, A.V.Rudinsky I.P.Pavlov Institute of Physiology, Russian Academy of Sciences, nab. Makarova 6, 199034 St.Petersburg, Russia Fax: +7 812 3280501; E-mail:lavr@infran.ru)

  2. A purpose of the first part of presented study was to investigate whether age, education, training, sex and emotional state influence on process of acceptance of the decision. This was done by measuring a minimal amount of information which is required to recognize a visual image depending on the level of different factors.

  3. Correlation between number of contour fragments needed for recognition of a visual scene (triangles) and trait anxiety score (circles)

  4. Thus, it was stated that the increasing of level of anxiety obstructs the recognition of visual signals and the acceptance of decision. We assume that emotional factor mainly reveals itself at the step of integrative analysis of flows of external and internal information. It is known that qualitative parameters of integrative processes are controlled by the nonspecific systems of the brain. So, the reported difficulty in recognition of visual signals can be explained by the negative influence of a mechanism of nonspecific regulation on the integration of sensory and memorable (bolted in memories) information under conditions of increasing anxiety.

  5. Thus:

  6. Integration of neurons in brain and connection of brain and psyche
