Abstract
Phobia treatment using a counter conditioning approach. This study is based in the believe that a kind of pavlovian conditioning is involved in phobias, and then, fear response is generalised to similar stimuli configurations. Treatment here described is based in counterconditioning effect. We worked with a canine subject that showed a strong fear in presence of high noises. We tried to produce an incompatible reaction to fear conditioned response. We used a reversion temporal series design (A-B-A) to prove treatment efficacy. Data treatment (visual analysis to detect presence-not presence of level changes, tendencies and tendency changes; and traditional statistic analysis) shows significant differences in dog behaviour between phases.
