Biological Foundations

• Basic Information Processing speed (Jensen, Eysenck)
  • Inspection Time
  • Reaction Time (mean and variability)
  • Eysenck: string length, neuronal error, transmission speed
  • Myelinization as the cause of transmission speed and efficiency
• Brain volume (total, white & grey matter volume, cortical thickness, corpus callosum, specific brain areas)
• White matter integrity (Penke)
• Post synaptic density (Hill)
• Fronto-Parietal Integration Theory (Jung & Haier)
• Electrical (magnetic) activity on the scull
  • Power in different frequency bands
  • Event-related potentials as markers of speed and information processing (P300, MMN, N100 etc)
