Abstract
A study was conducted with the aim of evaluating the effect of systematic desensitization and the zero-contingency procedure on phobic responses to hole-pattern figures in an individual with trypophobia. A psychology student from UDF Santa María who reported experiencing a phobia of hole-pattern figures participated in the study. The procedure followed a simple experimental design with reversal, in which systematic desensitization and the zero contingency procedure were implemented. A series of hole-pattern images were presented, and the frequency of phobic responses was recorded. The results showed a decreasing trend in the frequency of phobic responses to the stimulus presentation, suggesting that the combined techniques constitute an effective procedure for reducing trypophobia.
