The invention provides a modular neurocognitive function test method for drug addiction evaluation, and belongs to the field of addiction assessment. The problem that existing evaluation standards are not uniform is solved. The modular neurocognitive function test method comprises the following steps of S1, inputting external stimulation; S2, carrying out modularized neurocognitive function test; S3, carrying out behavior reaction output, wherein the step S2 comprises the following steps of S2.1, executing a function test; S2.2, carrying out negative emotion testing; S2.3, carrying out a reward motivation test; the step S2.1 comprises the following sub-steps of S2.1. 1, paying attention to a control test; S2.1.2, carrying out a reaction inhibition test; S2.1. 3, carrying out a plan processing test; S2.1. 4, carrying out a work memory test; S2.1. 5, carrying out a pre-estimation decision test; the step S2.2 comprises the following steps of S2.2. 1, carrying out a negative emotion behavior test; S2.2. 2, carrying out a negative emotion scale test; S2.2. 3, carrying out a negative emotion nerve image test; and the step S2.3 comprises the following steps of S2.3. 1, performing a reward motivation behavior test; S2.3. 2, carrying out a reward motivator scale test; and S2.3. 3, carrying out a reward motivator nerve image test. The method has the advantage of unified standard.
