Summary

In this study, the subconscious memory extinction therapy based on very brief exposure is used to intervene to reduce the alcohol craving of alcohol-dependent patients, prevent relapse, and observe the psychological craving, heart rate, skin conductance, and pupil diameter changes of the patients during the brief exposure extinction. The main questions it aims to answer are:

1. Whether subconscious extinction intervention would reduce psychological craving and alcohol relapse?
2. What is the mechanism of subconscious extinction intervention in alcohol dependence?

Conditions

Interventions

BEHAVIORAL

Very brief extinction

The very brief extinction presents a very short (33ms) repetitive sequence of alcohol cues, followed by a "masking" stimulus(117ms), which masks the alcohol cues. In the case of repeated exposure to alcohol stimulation, the response to the stimulation is desensitized at the level of unconscious processing.

BEHAVIORAL

Clearly visible extinction

The clearly visible extinction presents a repetitive sequence of alcohol cues(150ms) without a "masking" stimulus. In the case of repeat exposure to alcohol stimulation, the response to the stimulation is desensitized at the level of conscious processing.

BEHAVIORAL

Very brief neutral extinction

The very brief neutral extinction presents a very short (33ms) repetitive sequence of neutral cues, followed by a "masking" stimulus(117ms), which masks the neutral cues. In the case of repeated exposure to neutral stimulation, the response to the stimulation is desensitized at the level of unconscious processing.
