Study: NCT01501812

Intervention type: BEHAVIORAL
Intervention: Generalization pattern
Description: During evaluation a conditioning of a tone (conditioning stimulus) and aversive sound (metal scratch) will conduct (another tone which will be un-conditioning stimulus for control). Generalization patterns will be evaluated, by measuring the differentiation capability between different tones (neutral and aversive) before and after the conditioning, and after extinction phase. The generalization will also be measured by the generalization curve that plotted from displaying tones, different from the original tones, and asked the subject whether the current tone is original or new
