Q

Habituation vs Adaptation

A

Adaptation

  • purely physiological; neurons = NO CONSCIENCE
  • constant stimuli frequency, varying intensities
  • feeling of shirt disappearing
  • forgetting the smell of home

Habituation

  • stop paying attention
  • accustom to loud noises
  • increased freq / high freq exposure = decrease response !!!
  • non-associative learning
